Hidradenitis Suppurativa: An Underdiagnosed Skin Condition That Needs Better Imagry

The Condition Nobody's Heard Of — And Why Publishers Need to Change That

It affects up to 4% of the population. It's more common than multiple sclerosis. It causes painful, recurring lesions in some of the most sensitive areas of the body, can burrow beneath the skin creating tunnels, and leaves lasting scars — yet most people have never heard its name. Hidradenitis suppurativa, mercifully shortened to HS, is arguably the most underrepresented chronic inflammatory skin disease in medical publishing relative to how many people actually live with it. It also goes by another name — acne inversa — not because it's related to acne, but because it appears in the inverse locations: the skin folds rather than the face. For publishers, educators, and pharmaceutical communicators working in health communications, the gap between HS's prevalence and its visibility in medical media represents both a challenge and a significant opportunity. Science Source has the licensable imagery to help close it.

What Is Hidradenitis Suppurativa?

HS is a chronic inflammatory condition affecting the apocrine glands — specialized sweat glands concentrated in the armpits, groin, under the breasts, and inner thighs. When these glands and their surrounding hair follicles become blocked and inflamed, the result is painful, recurring abscesses that can rupture, tunnel beneath the skin, and cause significant scarring over time.

It is not caused by poor hygiene — a persistent and deeply damaging misconception that contributes to the stigma patients carry along with the condition itself. HS is an immune-mediated disease, driven by an overactive inflammatory response rather than anything a patient did or didn't do.

Clinicians categorize HS using the Hurley staging system, which describes three progressive levels of severity:

• Hurley Stage I — single or multiple abscesses without tunneling or significant scarring

• Hurley Stage II — multiple abscesses with the beginning of tunneling and scarring

• Hurley Stage III — extensive abscesses, advanced tunneling, and deep scarring across large areas of the body

That progression — from isolated lesions to a complex landscape of tunnels and scars — is one of the most important visual stories in dermatology, and one that demands more than a single image to tell.

HS in Context: The Most Underdiagnosed Condition in Dermatology

Despite its prevalence, patients with HS wait an average of seven to ten years for a correct diagnosis. In that time, they are frequently told they have recurring boils, infected ingrown hairs, or even sexually transmitted infections — misdiagnoses that delay treatment and compound the condition's psychological toll.

HS disproportionately affects women and people with darker skin tones, two groups historically underrepresented in dermatology photography and clinical research alike. The condition also carries an outsized psychosocial burden — chronic pain, wound care, scarring in intimate body areas, and persistent stigma around a condition many patients are too embarrassed to discuss with anyone, including their doctors.

Growing patient advocacy is beginning to shift that silence. Awareness campaigns, patient communities, and increasing media coverage are driving demand for model-released imagery that reflects who actually lives with HS — across genders, skin tones, and stages of disease. For medical publishers and medical affairs teams alike, that demand is both a responsibility and a market signal.

The pharmaceutical market for HS treatments was valued at $1.2 billion in 2024 and is projected to nearly double by 2033 — a growth curve that will generate sustained demand for pharmaceutical communications, promotional medical education, and continuing medical education resources, all of which require accurate, rights-managed imagery that picture researchers can license with confidence.

A Treatment Landscape Finally Catching Up

For most of its documented history, HS was managed with antibiotics, retinoids, and surgery — approaches that helped manage symptoms but rarely resolved the underlying inflammatory process. The past decade has brought a fundamental shift in understanding, and with it, a new generation of targeted therapies.

The science begins with the immune system. In HS, the body's inflammatory response goes into overdrive, driven by specific proteins called cytokines that signal immune cells to attack. Two cytokines in particular — TNF-alpha and members of the interleukin-17 (IL-17) family — have emerged as central drivers of the chronic inflammation that causes HS lesions to form, persist, and recur.

Biologic therapies work by targeting these specific proteins directly. TNF-alpha inhibitors bind to and neutralize the TNF-alpha protein, interrupting the inflammatory signal before it can trigger a flare. IL-17 inhibitors work along a different but related pathway — blocking the IL-17 proteins that activate immune cells, recruit neutrophils, and drive the cascade of inflammation that leads to abscess formation and tunneling. Some of the most recent biologics target both IL-17A and IL-17F simultaneously, blocking the inflammatory signal at two points in the pathway rather than one.

For patients who don't respond to biologics, a newer class of oral medications — JAK inhibitors — offers an alternative approach, interrupting inflammatory signaling at an earlier stage within the immune cell itself. Each of these mechanisms has a distinct visual story — from molecular pathway diagrams and immune cascade illustrations to clinical photography documenting treatment response — and pharma marketing and medical journal publishers increasingly need imagery that explains not just what these treatments do, but how they work at the cellular level.

Why Accurate HS Imagery Is So Hard to Find — And So Important

HS presents unique challenges for publishers and picture researchers that go beyond the clinical complexity of the condition itself.

The condition affects intimate body areas, which means photography requires careful patient recruitment, significant sensitivity, and clinical expertise that most generalist photographers simply don't have. Stigma compounds the problem — patients who have spent years being misdiagnosed are understandably reluctant to participate in medical photography projects.

The result is a chronic shortage of quality HS imagery in most stock libraries, at precisely the moment when demand is accelerating. Publishers covering the new wave of biologic approvals, patient advocacy organizations producing awareness campaigns, and pharmaceutical companies developing educational materials for healthcare providers are all searching for imagery that most agencies cannot supply.

Staging matters enormously. Hurley Stage I looks nothing like Hurley Stage III, and publishers need the full spectrum. Skin tone representation is particularly critical, given the condition's disproportionate impact on people with darker skin. And medical illustration is essential alongside photography — staging diagrams, anatomical cross-sections showing tunneling beneath the skin, body location maps, and immune pathway illustrations are all in active demand for clinical and pharmaceutical publishing.

What Science Source Brings to the Table

Science Source has built one of the most comprehensive HS collections available for licensing — developed specifically to serve the needs of picture researchers and publishers working in a space where accurate imagery is scarce and the stakes are high.

The collection includes rights-managed clinical photography across Hurley stages and body locations, including model-released images of underarm, breast, and groin presentations. Medical illustrations document the three progressive stages of the condition with clinical accuracy, including cutaway diagrams showing the tunneling beneath the skin that defines more advanced disease. Body silhouette illustrations map affected areas clearly — ideal for patient education materials, health communications campaigns, and pharmaceutical communications that need to convey complex information accessibly.

Skin tone diversity is represented across the collection, reflecting the real patient population that lives with this condition and the publishing industry's growing commitment to inclusive medical imagery.

Whether you are producing a pharma marketing campaign, a promotional medical education module, a clinical dermatology journal feature, or a continuing medical education resource, Science Source has the depth, the range, and the scientific accuracy to support that work.

COVID-19 and Cardiovascular Risk

Conventional wisdom holds that COVID-19 is a respiratory disease — a virus that colonizes the lungs and, for most patients, stays there. The epidemiological picture emerging several years into the pandemic complicates that view considerably. A substantial and expanding body of population-level research now links SARS-CoV-2 infection to elevated cardiovascular risk: heart attack, stroke, and related vascular events. Persisting well beyond the acute phase of illness. The mechanism, as it turns out, begins not in the lungs but at a single cell-surface receptor.

View our featured gallery: COVID-19 and Cardiovascular Disease →

It Starts With a Receptor, Not the Lungs

The link between SARS-CoV-2 and cardiovascular pathology begins with angiotensin-converting enzyme 2 (ACE2), a protein expressed on the surface of cells throughout the body, where it normally helps regulate blood pressure. ACE2 also happens to be the virus's entry point: the spike protein binds to it with notable specificity, in essentially a lock-and-key fashion.

The lungs draw the most clinical attention because alveolar cells are especially rich in ACE2 and tend to be where infection first becomes symptomatic. But ACE2 is expressed just as prominently on the endothelial cells lining blood vessels throughout the circulatory system — which is precisely what reframes this from a purely respiratory illness into a systemic vascular one.

A small etymological aside, for anyone who appreciates one: "corona" is Latin for crown, a reference to the ring of spike proteins studding the viral envelope, which under electron microscopy genuinely does resemble a coronet. A fitting name, given how much of the pathology traces back to that structure.

What Happens to Blood Vessels During Infection

Blood vessels are lined by a single layer of cells, the endothelium, which is, remarkably, thinner than a sheet of paper yet performs an outsized physiological role: keeping blood flowing smoothly, regulating clotting, and controlling what passes into surrounding tissue.

When SARS-CoV-2 infects or provokes inflammation in endothelial cells, the resulting condition, endothelial dysfunction, alters vessel behavior in several consequential ways:

• Increased endothelial "stickiness," raising the likelihood of platelets and clotting factors adhering to vessel walls

• A broader systemic inflammatory response, which further irritates vascular tissue

• Disruption of the normal balance between clot formation and clot breakdown

None of this occurs in isolation. It's the underlying reason COVID-19 has been associated with elevated rates of clotting events — not only during acute infection, but for months afterward.

Who's Most at Risk?

Cardiovascular risk following COVID-19 isn't uniformly distributed across a population. Several well-established factors appear to compound it, and readers with any familiarity with cardiovascular health will recognize most of them immediately:

• Age: older adults carry elevated risk both during acute infection and in its aftermath.

• Obesity: independently associated with more severe COVID-19 illness and, separately, with cardiovascular risk generally.

• Diabetes: a known contributor to vascular damage on its own, which appears to compound COVID-related vascular stress rather than merely coexist with it.

• Hypertension: among the most frequently observed comorbidities in COVID patients who go on to experience cardiac or cerebrovascular events.

• Pre-existing cardiovascular disease: a prior heart attack, stroke, or diagnosed cardiac condition raises baseline risk considerably.

• Smoking: a well-documented contributor to endothelial damage that appears to layer onto, rather than operate independently of, COVID-related vascular effects.

None of these risk factors are unique to COVID-19; they're the same variables that appear in cardiovascular health conversations more broadly. What's notable is how consistently they recur across COVID-cardiovascular research specifically — suggesting the virus may be amplifying existing vulnerabilities rather than introducing an entirely new risk pathway.

Stroke, Heart Attack, and the Long Tail of "Long COVID"

The cardiovascular effects of COVID-19 show up in more than one form, and across more than one timeline.

Ischemic stroke — the result of a blood clot obstructing blood flow to the brain — is the subtype most consistently associated with COVID-19, consistent with the virus's broader tendency to promote clotting. Stroke medicine has a well-known saying, "time is brain," reflecting how quickly neural tissue is affected once blood flow is interrupted — part of why any stroke symptoms warrant immediate emergency evaluation.

Cardiac involvement extends well beyond stroke:

• Heart attack (myocardial infarction): resulting from blocked coronary blood flow, via the same clotting mechanism implicated in ischemic stroke.

• Myocarditis: inflammation of the heart muscle, reported at elevated rates following SARS-CoV-2 infection.

• Arrhythmia: irregular heartbeat, another effect linked to post-COVID inflammatory processes.

• Deep vein thrombosis and pulmonary embolism: clotting conditions affecting the legs and lungs, respectively, both consistent with COVID-19's broader effect on clotting.

Timing is a meaningful variable here. Some events occur during or shortly after acute infection, while hospitalized patients are already under close monitoring. Others manifest considerably later, often discussed under the "long COVID" umbrella, underscoring that cardiovascular risk isn't confined to the acute or most severe phase of illness.

A Story Best Told With the Right Imagery

None of this is visible to the unaided eye: a spike protein engaging a receptor, an inflamed vessel wall, a clot forming inside an artery. That's where strong imagery does what prose can't.

Our collection covers this topic in full: micrographs of clots and damaged endothelium, precise illustrations of stroke and heart attack, and diagnostic imaging of real clinical presentations, all backed by accurate metadata. With more than sixty years sourcing and vetting science and medical imagery, we're also glad to help track down exactly what a piece needs — free of charge, as part of the research support we offer every client.

Chemistry Experiment Images That Teach Science Well

Here's something chemistry teachers have known for decades: students remember the day something caught fire. Not the equation on the board, but the magnesium ribbon burning with an intense white light. Not the definition of surface tension, but the paper clip somehow floating on water.

Chemistry is one of the few sciences that can consistently get an audible reaction from an audience. Yet it's also one of the sciences most often illustrated with generic lab photos—a gloved hand holding a flask, a beaker of brightly colored liquid, or a periodic table hanging on the wall. For publishers, that disconnect is a real challenge. The right image doesn't just fill space on a page; it helps explain the science.

Gallery of Stock Chemistry Experiment Images

At Science Source, we've built our collection of chemistry experiments with that goal in mind. A well-chosen photograph can do more than illustrate a reaction—it can help readers understand the underlying principle. In this article, we'll look at some of our most-licensed chemistry experiment images, what makes them effective, and why publishers, educators, and science communicators continue to rely on them.

Classic Chemistry Experiment Photography: Reactions That Teach

Certain chemistry demonstrations have been classroom favorites for generations because they make invisible chemical principles easy to see. Our high-speed photography captures these reactions in ways that standard lab photography cannot, freezing the split-second moments that help explain what's actually happening. Some of our most frequently licensed images in this category include:

• Rubidium reacting with water: isolates the ignition moment that makes alkali metals react dramatically, illustrating ionization energy.

• Nitrogen triiodide explosion: one of the most contact-sensitive reactions in chemistry, captured at high speed.

• Magnesium ribbon burning: the brilliant white flame of combustion, a classroom classic.

• Hydrogen balloon exploding: used extensively to illustrate combustion, gas properties, and energy release.

Even simple demonstrations have strong educational value. Reactions such as lemon juice and baking soda, beet juice or red cabbage pH indicators, and the classic vinegar and baking soda experiment are staples of introductory chemistry because they clearly illustrate fundamental concepts. We photograph these experiments with the same attention to scientific accuracy as our more dramatic reaction photography. The color changes are genuine, the reactions are authentic, and the images accurately represent the chemistry taking place.

Crystal Formation, Precipitation, and the Visual Side of Chemistry

Some of our most-licensed chemistry images aren't dramatic reactions at all. Instead, they reveal the structure and behavior of matter in ways that are both scientifically informative and visually striking. For art directors, these images work equally well as compelling visuals and as accurate scientific illustrations.

• Precipitation of lead iodide — a sudden yellow cloud forming as two clear solutions meet. As close to visual poetry as chemistry gets.

• Crystal growth in a supersaturated solution — the geometry of matter organizing itself in real time.

• Iodine crystals sublimating — solid to vapor, with no liquid phase, captured as a still.

• Dispersion of white light — the spectrum emerging from a prism, accurate in its wavelength rendering.

• Food coloring diffusing in water — slow, deliberate, and deeply useful for illustrating diffusion and entropy.

One of the best examples is our surface tension series, including the classic paper clip floating on water and step-by-step photographs of the experiment. It illustrates a concept that seems to defy common sense, using real photography rather than a diagram to show what's happening.

Everyday Chemistry Experiments: Stock Images for Introductory Publishing

Not every chemistry image a publisher needs features bubbling beakers or colorful reactions. Much of our collection focuses on chemistry in everyday life—the science behind familiar materials, foods, household products, and common phenomena. These images are especially useful for introductory textbooks, science journalism, and general-interest publications that want to make chemistry relatable while remaining scientifically accurate.

• Denaturation of protein through egg cooking — a legitimate biochemistry demonstration in a domestic setting.

• Boyle's Law with marshmallows in a vacuum — a real experimental demonstration of gas behavior under pressure, not a simplification.

• Viscosity comparison between liquids — clean, comparative, and immediately useful for physical chemistry contexts.

• Potato battery — electrochemistry made tangible for younger audiences or introductory publishing.

• Food science experiment — bridges chemistry and biology for nutrition, health, and consumer science publishers.

Our historical chemistry collection serves a different purpose. Images such as 18th-century engravings of Henry Cavendish's experiments on "factitious air" and illustrations from the 1856 Chemistry of Combustion and Illumination help publishers place modern chemistry in its historical context. They are frequently used in textbooks and articles covering the development of the scientific method, the history of chemistry, and the transition from alchemy to modern chemical science.

Why Scientific Accuracy in Chemistry Stock Photography Matters

Chemistry is one of the disciplines where an inaccurate image can do more than weaken a page—it can mislead the reader. Publishers, educators, and science communicators need visuals that accurately represent the science, not just the look of a laboratory. That means paying attention to details such as:

• The color of a flame test, which identifies the element being tested.

• The stage of a reaction being photographed, since timing can affect what the image represents.

• Laboratory apparatus that reflects an actual experimental setup rather than a stylized prop.

• Current and correctly assigned chemical hazard pictograms.

Our photographs of Hoffman's apparatus are among our most frequently licensed chemistry images because they accurately depict electrolysis for textbooks, digital learning platforms, and reference publications. The same is true of our series of chemical equilibrium experiments and our hazard pictogram imagery, including potassium dichromate and nickel nitrate.

For picture researchers and art directors, the question isn't simply, "Does this look like chemistry?" It's, "Does it represent the chemistry correctly?" That's where scientifically accurate image collections make a difference.

License Scientifically Accurate Chemistry Images

Many classic chemistry demonstrations remain popular because they clearly illustrate fundamental scientific principles. The iodine clock reaction, for example, is widely used to demonstrate chemical kinetics. After a predictable delay, the solution suddenly turns deep blue, providing a memorable visual example of how reaction rates can be controlled and measured.

The same philosophy guides our chemistry collection. Whether documenting a dramatic reaction, a simple classroom experiment, or historical laboratory equipment, our goal is to provide images that are both visually engaging and scientifically accurate. The collection is used by textbook publishers, educational media, science journalists, and corporate communicators who need chemistry imagery they can trust.

If you're developing a chemistry textbook, educational resource, article, or digital learning platform, we'd be happy to help you find the right images for your project.

Eczema: The Itch That Rewrites Daily Life and the Images That Tell Its Story

If you've ever watched a baby scratch relentlessly at their own skin, or seen an adult with raw, cracked hands try to explain why they can't simply "stop itching," you already understand something essential about eczema: it is far more disruptive than it looks, and it looks different on everyone. Formally known as atopic dermatitis, eczema affects an estimated 230 million people worldwide — making it one of the most prevalent chronic skin conditions on the planet. And yet, for all its reach, it remains one of the most visually underserved topics in medical publishing. That gap is closing fast, and the demand for accurate, diverse, clinically credible imagery has never been greater.

Eczema — Atopic Dermatitis Stock Images

What Is Eczema? The Short Version

• Chronic inflammatory skin condition characterized by dry, itchy, inflamed skin that flares and remits over time

• Not contagious, caused by a combination of genetic, immune, and environmental factors that compromise the skin's barrier function

• Approximately 50% of cases begin during the first year of life and 85% by age five, but it can develop or persist at any age, including in older adults

• Affects all skin tones, ages, and body types, but presents very differently depending on skin tone, age, and body location

• Common presentation sites include the inner elbows, backs of knees, hands, face, neck, and scalp, though it can appear anywhere

• Part of the "atopic triad": eczema frequently occurs alongside asthma and allergic rhinitis, reflecting its systemic immune roots

• Symptoms range from mild dryness and irritation to severe, widespread inflammation that disrupts sleep, work, and quality of life

Eczema in Context: Who Gets It and Why It's Undercovered

• Prevalence rates in the US are estimated at 8% to 18% in children and up to 10% in adults, making it one of the most common conditions a medical publisher will ever need to illustrate

• Disproportionately affects urban populations and higher-income countries, though the reasons remain an active area of research

• Despite its prevalence, eczema has been chronically underrepresented in medical imagery, particularly in children and across diverse skin tones

• On darker skin, eczema may appear brown, violet, or gray rather than the classic red, and lichenification (skin thickening from chronic scratching) can be more pronounced, distinctions that are clinically meaningful and visually distinct

• Significant stigma around visible skin conditions, combined with the particular sensitivity around photographing infants and children, has historically made quality eczema photography scarce

• Growing patient advocacy and regulatory pressure for diverse representation in medical education are driving urgent demand for imagery that reflects real patient populations

A Treatment Revolution — Still in Progress

Eczema was once managed almost exclusively with moisturizers, topical corticosteroids, and broad immunosuppressants that had significant long-term side effects. The past decade has brought a remarkable transformation:

• Dupilumab (approved 2017) — the first biologic approved for atopic dermatitis, targeting the IL-4 and IL-13 pathways, it changed the standard of care for moderate to severe disease and opened the door to a new era of targeted therapy

• Lebrikizumab (approved 2024) — an IL-13 inhibitor with a monthly maintenance dosing schedule after an initial loading phase, making it the most convenient long-term biologic option currently available

• Nemolizumab (approved December 2024) — the first biologic to specifically target IL-31, the key cytokine responsible for the intense itching that is often more debilitating than the visible rash itself

• JAK inhibitors — oral and topical options (abrocitinib, upadacitinib, ruxolitinib) providing additional pathways for patients who don't respond to biologics

• Ongoing clinical trials continue to identify new immune targets, making atopic dermatitis one of the most active areas in all of dermatology publishing

Each new approval generates a fresh wave of pharmaceutical communications, patient education materials, continuing medical education content, and journal coverage — all of which require current, accurate, licensable imagery.

Why Accurate Eczema Imagery Matters for Publishers

Eczema is deceptively difficult to illustrate well. The condition is highly variable and deeply personal, carrying an emotional weight that generic imagery consistently fails to capture.

Childhood Eczema Gallery

• Age range is critical: eczema in infants looks nothing like eczema in adults, and pediatric imagery requires particular care around model releases and sensitivity

• Skin tone diversity is non-negotiable: the clinical presentation differs significantly across skin tones, and educational materials that show only one presentation do a disservice to patients and clinicians alike

• Body location matters: inner elbows and knees are the classic teaching images, but hands, face, scalp, and eyelids are all common sites with distinct visual and editorial needs

• Severity spectrum: mild, moderate, and severe presentations serve entirely different publishing contexts, from consumer health magazines to clinical dermatology journals to pharmaceutical approval submissions

• The itch is invisible: medical illustration plays an essential role in explaining the immune cascade, skin barrier dysfunction, and nerve pathway involvement that drives the itch-scratch cycle; photography alone cannot tell this story

• Complications require their own imagery: eczema herpeticum (a serious viral complication), infected eczema, and contact dermatitis overlapping with atopic dermatitis all represent distinct clinical scenarios with real publishing demand

What Science Source Brings to the Table

Science Source offers one of the most extensive eczema and atopic dermatitis collections available for licensing, built specifically to serve the needs of medical publishers, pharmaceutical communicators, and healthcare educators.

• Clinical photography spanning infants, children, and adults — including model-released images across a range of ages, skin tones, and body locations

• Images documenting mild through severe presentations, including eczema herpeticum and other complications

• Diverse skin tone representation, including clinical photography on darker skin tones where the condition's presentation differs meaningfully from textbook imagery

• Medical illustrations explaining skin barrier dysfunction, immune pathway involvement, and the mechanisms targeted by modern biologic therapies

• A knowledgeable picture research team is available to help you find exactly what your project needs. No obligation

A Comprehensive Resource for Psoriasis Visuals

For more than 2,500 years, physicians have been trying to understand psoriasis. Ancient Egyptian medical texts described skin conditions that may have been psoriasis. Greek physicians later gave the disease its name, derived from psora, meaning itch. For centuries, psoriasis was confused with other skin disorders, including leprosy, reflecting just how little was known about the condition.

Today, psoriasis is recognized as a chronic immune mediated disease that affects an estimated 125 million people worldwide. Yet despite its prevalence, psoriasis remains widely misunderstood. It is often dismissed as a cosmetic issue when, in reality, it can affect multiple body systems, impact mental health, and significantly reduce quality of life.

As awareness grows and treatment options continue to expand, publishers, healthcare communicators, educators, and pharmaceutical companies need visual content that accurately reflects the many faces of psoriasis. A single image cannot tell the whole story.

What Is Psoriasis?

Psoriasis is a chronic autoimmune disease that causes the immune system to mistakenly accelerate skin cell production. Instead of shedding and renewing over the course of several weeks, skin cells accumulate in just a few days, creating thickened areas of inflamed skin known as plaques.

The condition is not contagious and can affect people of all ages, genders, and ethnic backgrounds.

There are five major forms of psoriasis, each with a distinct appearance:

• Plaque psoriasis: The most common form, characterized by raised, scaly patches that often appear on the elbows, knees, scalp, and lower back.

• Guttate psoriasis: Small, drop shaped lesions that frequently develop after infections such as strep throat.

• Inverse psoriasis: Smooth, inflamed patches found in skin folds, including the underarms and groin.

• Pustular psoriasis: White pustules surrounded by reddened skin.

• Erythrodermic psoriasis: A rare but serious form that can affect large areas of the body and may require urgent medical care.

Psoriasis typically follows a cycle of flare ups and periods of remission. Symptoms may improve for months or even years before returning.

The disease also extends beyond the skin. Up to 30 percent of people with psoriasis develop psoriatic arthritis, an inflammatory joint condition that can cause pain, stiffness, swelling, and long term joint damage. For many patients, psoriasis is a systemic disease rather than simply a skin disorder.

Psoriasis affects an estimated 125 million people worldwide, including about 8 million people in the United States. While it can develop at any age, it is most often diagnosed during two peak periods, in a person’s 20s and again in their 50s.

Despite its prevalence, psoriasis has historically been underrepresented in medical media and educational imagery. Stigma surrounding visible skin conditions can make patients less likely to participate in photography and awareness campaigns. Dermatology photography has also long lacked representation across diverse skin tones, even though psoriasis may appear quite differently on darker skin, often presenting as violet, gray, or brown rather than red.

As publishers, healthcare organizations, and advocacy groups work to address these gaps, demand is growing for more accurate, inclusive, and compassionate visual representation. Better imagery not only reflects the diversity of patients living with psoriasis, it also supports improved education, awareness, and diagnosis.

A New Era of Psoriasis Treatment

The treatment landscape for psoriasis has changed dramatically over the past two decades.

Traditional therapies such as topical corticosteroids, moisturizers, phototherapy, and systemic medications continue to play important roles in treatment. However, advances in immunology have transformed care for many patients with moderate to severe disease.

Biologic therapies have been particularly significant. These injectable medications target specific components of the immune system, including TNF alpha, IL 17, and IL 23 pathways. By focusing on precise immune mechanisms, biologics can dramatically reduce symptoms while improving long term disease management.

Newer oral medications, including JAK inhibitors and other targeted therapies, are providing additional options for patients, especially those with psoriatic arthritis.

For healthcare communicators, this rapid pace of innovation creates a constant need for current, scientifically accurate visual content.

Why Accurate Psoriasis Imagery Matters

Psoriasis presents unique challenges for publishers because there is no single image that represents the condition.

A patient education brochure, a dermatology textbook, a pharmaceutical marketing campaign, and a clinical journal article may all require very different visual approaches.

Skin Tone Representation

Psoriasis can appear differently depending on skin tone. While inflammation often appears red on lighter skin, it may appear violet, gray, brown, or darker than the surrounding skin in people with more melanin. Diverse clinical photography helps ensure that educational materials accurately reflect real patient populations.

Disease Severity

The visual appearance of mild psoriasis differs dramatically from severe disease. Publishers often need imagery spanning a broad spectrum of presentations, from localized plaques to extensive body involvement.

Body Location

Psoriasis affects many areas of the body, including the scalp, nails, hands, feet, face, and skin folds. Different locations create different visual and educational needs.

Psoriatic Arthritis

As awareness grows regarding the systemic nature of psoriasis, demand is increasing for imagery that illustrates joint involvement. Clinical photographs, diagnostic imaging, and anatomical illustrations help tell a more complete story of the disease.

Psoriatic Arthritis Photography and Medical Illustrations

Medical Illustration

Photography alone cannot explain the complex immune processes underlying psoriasis. Medical illustrations remain essential for textbooks, patient education materials, pharmaceutical communications, and scientific publications. Cross sections of skin, immune pathway diagrams, and treatment mechanism illustrations help make complex concepts accessible.

Historical Context

For academic publishing, long form journalism, and documentary projects, historical medical illustrations and archival photography provide valuable context. These materials help trace how understanding and treatment of psoriasis have evolved over time.

A Comprehensive Resource for Psoriasis Visuals

Science Source offers a broad collection of psoriasis and psoriatic arthritis imagery for healthcare, educational, and publishing projects. The collection includes clinical photography across a range of disease severities, body locations, skin tones, and patient demographics, along with diagnostic imaging, medical illustrations, and historical artwork. From patient education materials and clinical journals to pharmaceutical communications and medical textbooks, these visuals help accurately represent the many ways psoriasis affects the body. Science Source provides the depth, diversity, and scientific accuracy needed to tell a more complete story of this complex disease.

Visualizing Fragile X Syndrome

Under the microscope, it appears as a thread on the verge of breaking. A narrow constriction near the tip of the X chromosome's long arm. This distinctive chromosomal feature, known as a "fragile site," gave Fragile X syndrome its name and provided one of the earliest visual clues to a disorder that would transform our understanding of genetics, neurodevelopment, and inherited intellectual disability.

Today, Fragile X syndrome remains the most common inherited cause of intellectual disability and one of the most common known single gene causes of autism spectrum disorder. While diagnosis has moved from the cytogenetics laboratory to molecular genetic testing, visual representations of the disorder continue to play a vital role in medical education, scientific publishing, and patient communication.

What Is Fragile X Syndrome?

Fragile X syndrome is an X-linked genetic disorder caused by an expansion of CGG trinucleotide repeats within the FMR1 (Fragile X Messenger Ribonucleoprotein 1) gene on the X chromosome. In unaffected individuals, the gene typically contains fewer than 45 CGG repeats. When the repeat expansion exceeds approximately 200 copies, a full mutation, the gene becomes hypermethylated and transcriptionally silenced.

The loss of FMR1 expression results in a deficiency of fragile X messenger ribonucleoprotein (FMRP), an RNA-binding protein essential for synaptic development, neuronal plasticity, and normal cognitive function. Without sufficient FMRP, neural circuits develop differently, contributing to the cognitive, behavioral, and developmental features associated with the condition.

Fragile X syndrome affects an estimated 1 in 4,000–7,000 males and approximately 1 in 6,000–11,000 females worldwide. Because males possess only one X chromosome, they are generally more severely affected, whereas females often exhibit a broader range of clinical outcomes due to X-chromosome inactivation.

Gallery of Fragile X Syndrome visuals available for licensing.

The Challenge of Visualizing a Variable Disorder

Fragile X syndrome presents with remarkable clinical variability. Some individuals experience mild learning disabilities, while others have significant intellectual impairment, developmental delays, autism spectrum features, anxiety, attention deficits, sensory sensitivities, or social communication challenges.

Medical literature frequently describes characteristic physical findings, including an elongated face, prominent ears, a high-arched palate, and, after puberty in males, macroorchidism. Yet no single photograph can fully represent the diversity of people living with Fragile X syndrome.

More Information

This variability highlights the importance of scientifically accurate medical illustrations, infographics, and educational graphics. Well-designed visuals can communicate core clinical and genetic concepts without implying that every individual shares the same appearance or experiences the same symptoms.

From Cytogenetics to Molecular Genetics

The syndrome's name originates from a striking cytogenetic observation. When cells were cultured under specific laboratory conditions, researchers observed a constriction or apparent break at Xq27.3, the chromosomal location of the FMR1 gene. For many years, identifying this fragile site was an important diagnostic technique.

Today, molecular testing has largely replaced cytogenetic methods. DNA based assays can determine CGG repeat number, identify methylation patterns, and distinguish between normal, intermediate, premutation, and full-mutation alleles with far greater accuracy.

As diagnostic technologies have evolved, so too have the images used to explain the disorder. Contemporary educational materials increasingly rely on molecular diagrams, chromosome illustrations, gene maps, repeat-expansion graphics, and pathway based visualizations that help readers understand the underlying biology.

Why High-Quality Fragile X Visuals Matter

More Information

For publishers, educators, and healthcare communicators, Fragile X syndrome presents a unique visual challenge: conveying complex genetic mechanisms while accurately representing a highly variable human condition.

Medical textbooks require imagery that reflects current scientific understanding. Continuing education materials benefit from graphics that clarify inheritance patterns and molecular mechanisms. Genetic counseling resources rely on visuals that make abstract genomic concepts more accessible to patients and families.

The most effective imagery does more than illustrate a diagnosis. It provides context, communicates scientific accuracy, and supports learning without oversimplification or sensationalism.

Sourcing Scientifically Accurate Fragile X Syndrome Imagery

When selecting visual content, accuracy should extend beyond aesthetics. Chromosomal diagrams should correctly identify the FMR1 locus at Xq27.3. Molecular illustrations should accurately depict CGG repeat expansion and gene silencing. Clinical imagery should be accompanied by an appropriate context that reflects the condition's broad phenotypic spectrum.

For scientific publishers, healthcare organizations, and educational institutions, the professionally curated stock imagery at Science Source offers an efficient alternative to unverified online sources. Carefully reviewed medical illustrations, infographics, and research-based visual assets help ensure consistency, accuracy, and compliance with publication standards.

As our understanding of Fragile X syndrome continues to evolve, the need for precise, evidence-based visual communication grows alongside it. Whether illustrating a chromosome, a molecular pathway, or the lived experience of affected individuals, high-quality imagery remains an essential tool for translating complex genetics into meaningful understanding.

Grace Hopper and the First Computer Bug: A Legendary Legacy

Did you know that the first instance of “debugging” a computer involved an actual insect? In 1947, engineers working on the Mark II computer at Harvard University discovered a moth trapped in a relay, causing a malfunction. Grace Hopper, a pioneering computer scientist, recorded the incident in the logbook—coining the now-famous term “debugging.” Ever since, “debugging” has become a standard part of computer science vocabulary.

Grace Hopper, affectionately known as “Amazing Grace,” achieved numerous milestones in computer science. She was the first to use a compiler to translate English into computer code, making programming more accessible. Hopper invented COBOL, one of the first and most influential programming languages still in use today, and she played a key role in developing the UNIVAC—the first commercially produced computer designed for business and data processing.

Gallery of Grace Hopper Images

Hopper’s academic journey was equally impressive. She earned her Ph.D. in mathematics and mathematical physics from Yale University and taught at Vassar College. During World War II, she sought to join the WAVES, the women’s branch of the U.S. Naval Reserve. Though her mathematical talents were deemed too valuable for typical service, she was granted a special commission and assigned to the Bureau of Ships Computation Project at Harvard as a lieutenant, junior grade.

Grace Hopper’s distinguished career continued for decades. She finally retired at the age of 79 as a Rear Admiral, making her the oldest active-duty officer in the U.S. Navy at the time. Her groundbreaking work was recognized with many honors, including the Presidential Medal of Freedom.

From the first computer “bug” to revolutionizing how we communicate with machines, Grace Hopper’s legacy continues to inspire generations of scientists, engineers, and innovators.

CAR T-Cell Therapy: Engineering the Immune System to Fight Cancer

What if your own immune cells could be trained to recognize and destroy cancer?

This is no longer a futuristic idea—it’s happening right now.

In 2017, the U.S. Food and Drug Administration approved CAR T-cell therapy, a groundbreaking treatment often described as a “living drug.” Since then, more than 35,000 patients have received it, offering new hope where traditional therapies have failed.

How It Works

View Preview

CAR T-cell therapy harnesses the power of your immune system in a highly personalized way:

First, doctors collect a blood sample and isolate T-cells—white blood cells that play a central role in immune defense. In the lab, these cells are genetically modified to produce Chimeric Antigen Receptors (CARs), which allow them to recognize specific cancer cells.

Once reprogrammed, the cells are multiplied and infused back into the patient’s body. From there, they actively seek out and destroy cancer cells with precision.

A Targeted Approach

A cancer patient's own blood is drawn, modified in a lab, and returned weeks later as a living treatment. It sounds like something out of a near-future film. It's actually standard practice at cancer centers around the world, and it's been since 2017, when the FDA approved the first chimeric antigen receptor (CAR) T-cell therapy, tisagenlecleucel, for a form of pediatric leukemia.

Today there are seven FDA-approved CAR T-cell therapies on the market, covering several types of leukemia, lymphoma, and multiple myeloma. For publishers covering oncology, immunology, or biotechnology, it's one of the more visually compelling stories in modern medicine — and one that depends heavily on good imagery to explain, since the mechanism is almost entirely invisible to the naked eye.

What CAR T-Cell Therapy Actually Does

The "CAR" in CAR T-cell therapy stands for chimeric antigen receptor — chimeric meaning made of parts from different sources, much like the mythological chimera that lent the term its name. That's a fitting description, because the receptor itself is an engineered hybrid: part antibody, part T-cell signaling machinery, stitched together to give an ordinary immune cell a new and very specific job.

The process starts with leukapheresis, a procedure that filters T-cells out of a patient's blood. Those T-cells are sent to a lab, where a disarmed virus is used to insert the gene for the CAR into the cell's DNA. The receptor that results is built to recognize a particular protein on the surface of cancer cells — CD19 on many leukemias and lymphomas, BCMA on multiple myeloma. Once the modified cells are grown into the millions and infused back into the patient, they circulate through the body, latch onto cancer cells displaying that target protein, and trigger their destruction.

It's worth noting how different this is from chemotherapy, which works by killing rapidly dividing cells broadly, healthy and cancerous alike. CAR T-cells are trained for one target. That precision is the whole point, and it's also why the therapy is often called a "living drug" — it isn't a compound that clears the body in hours, but a population of cells that can persist and keep working for years.

A Surprisingly Durable Effect

View Preview

One of the more striking findings to come out of long-term CAR T-cell follow-up studies is just how durable remission can be. Patients in some of the earliest trials, treated more than a decade ago, still have detectable CAR T-cells circulating in their blood and remain cancer-free. That kind of staying power was not a given — many immune therapies fade over time as the engineered cells die off or the body clears them.

Researchers are still working out why some patients respond this way and others don't, which has made CAR T-cell biology one of the more active corners of cancer research. It also explains why this therapy, originally developed for blood cancers, is now being tested far beyond them — in early trials for solid tumors such as glioblastoma and pancreatic cancer, and even in autoimmune diseases like lupus, where the same "seek and destroy" logic is being redirected at malfunctioning immune cells rather than cancer cells.

Why This Story Is Hard to Tell Without the Right Images

CAR T-cell therapy is a genuinely difficult subject to illustrate. There's no tumor to photograph shrinking on a scan, no visible wound, no obvious before-and-after. The actual event being described — a re-engineered T-cell recognizing and binding to a cancer cell — happens at a scale measured in microns. For editors and writers working on this topic, that creates a real gap between the science and what a reader can see.

This is where electron micrographs and medical illustration do work that prose alone can't. A scanning electron micrograph showing a T-cell physically attached to a cancer cell makes the abstract idea of "targeted immune attack" concrete in a way no diagram of arrows and labels really can. A well-rendered 3D illustration of the receptor itself helps readers understand that a CAR isn't a drug in the traditional sense, but a piece of engineered molecular architecture sitting on the surface of a living cell.

Because this is a fast-moving field — new approvals, new targets, expansion into solid tumors and autoimmune disease — publishers also need imagery that won't read as dated or oversimplified next to the current science. Generic "cells under a microscope" stock photography tends to flatten a nuanced mechanism into something generic. Accurate labeling, correct cell morphology, and captions that reflect current terminology matter more here than in most science topics, simply because so few readers (or writers) have a strong mental picture of what a T-cell or a chimeric receptor actually looks like to begin with.

A Field Still Being Written

CAR T-cell therapy isn't a finished story. New CAR designs are in trials that aim to reduce side effects like cytokine release syndrome, "off-the-shelf" allogeneic versions are in development to make treatment faster and cheaper, and researchers are racing to crack the solid-tumor problem that has so far limited this approach mostly to blood cancers. Each of those threads will need its own visual vocabulary as the science evolves — which is part of why an imagery collection in this space needs to be maintained as carefully as the science itself.

How Marie Curie Saved Lives, Women's History Month

She Developed Mobile X-Rays to Save Lives in World War I

When people think of Marie Curie, they often think of her Nobel Prize–winning discoveries in radioactivity. But one of her most impactful contributions came during World War I, when she helped bring X-ray imaging directly to the battlefield.

At the time, doctors struggled to locate bullets and shrapnel in wounded soldiers. Surgery was often slow, imprecise, and life-threatening.

Curie changed that.

GALLERY OF MARIE CURIE STOCK HISTORY CONTENT

She developed mobile radiography units— later known as “Little Curies”—that could travel to field hospitals. These vehicles allowed doctors to see inside the body in real time, dramatically improving treatment and survival rates.

A Mother and Daughter on the Front Lines

Curie’s work became a family mission. Her daughter, Irène Joliot-Curie, joined her in operating the X-ray units and training others.

Together, they established radiology programs, equipped over 200 units, and trained technicians—many of them women—to use this new technology under wartime conditions.

It’s estimated that more than a million soldiers benefited from these mobile X-ray services.

A Lasting Medical Legacy

Today, X-ray imaging is a standard diagnostic tool around the world. Curie’s wartime innovation helped transform it from a scientific discovery into a practical, life-saving medical technology.

Her legacy is not only in what she discovered—but in how she applied science to save lives.

The Vagus Nerve: Hype, Science, and Clinical Reality

The vagus nerve has recently become a popular topic in wellness media and social platforms, often promoted as a newly discovered key to health and longevity. But what is the vagus nerve, and what does medical science actually say about its role in human health?

The brain contains 12 pairs of cranial nerves, which emerge directly from the brain and brainstem. Most cranial nerves serve sensory or motor functions in the head and neck such as vision, hearing, smell, and facial movement. The vagus nerve is different.

GALLERY OF VAGUS NERVE STOCK IMAGES

Extending from the brainstem into the chest and abdomen, the vagus nerve plays a central role in regulating the autonomic nervous system (ANS). This system controls involuntary body functions such as:

• Heart rate

• Breathing

• Blood pressure

• Digestion, including enzyme secretion and peristalsis

• Communication between the gut and brain

The autonomic nervous system has two primary branches:

• The sympathetic nervous system (SNS), often described as the “fight-or-flight” response

• The parasympathetic nervous system (PNS), which supports “rest-and-digest” functions

The vagus nerve is the primary driver of parasympathetic activity, helping maintain internal balance, or homeostasis.

Vagus Nerve Stimulation: Evidence-Based Applications

Despite sweeping wellness claims suggesting vagus nerve stimulation (VNS) is a cure-all, clinical applications are more limited.

Physicians have used implantable vagus nerve stimulators, devices similar in appearance to cardiac pacemakers, for decades. These devices deliver controlled electrical impulses to the nerve and are typically prescribed when conventional treatments have proven insufficient.

Currently, VNS therapy is most commonly used for:

• Drug-resistant epilepsy

• Treatment-resistant depression

• Stroke rehabilitation support

Ongoing research continues to explore its broader therapeutic potential, but its clinical use remains carefully regulated and condition-specific.

Medical Imaging for Emerging Therapies

As conversations around neuromodulation and autonomic regulation continue to grow, access to accurate, high-quality medical imagery is essential for educators, publishers, and healthcare communicators.

Science Source offers extensive medical and scientific stock photography—from traditional healthcare procedures to advanced treatments, including implantable vagus nerve stimulators and neurological therapies.

The Science of the Measles

The first written description of measles appeared in the 9th century, recorded by Persian physician Muhammad ibn Zakariya al-Razi.

This highly contagious viral infection originated from a mutation of a bovine disease called rinderpest. Through global vaccination efforts, rinderpest was eradicated in 2011.

While cattle are now safe, humans remain vulnerable to the measles virus.

With global travel, measles spread rapidly across continents, leaving illness and death in its wake.

GALLERY OF MEASLES STOCK IMAGES

Those infected typically develop a high fever, cold-like symptoms, and a rash. Most recover within a few weeks, but some develop pneumonia or encephalitis. Pregnant women face the risk of severe complications, including harm to their unborn child.

The worst U.S. outbreak occurred before the vaccine was developed, causing nearly 500 deaths and over half a million infections.

The measles vaccine, developed in 1963 and widely available by 1971, is 97% effective. Yet some still put children—and others—at risk by avoiding vaccination. Even a mild case can transmit the virus to infants, older adults, or those with weakened immune systems, leading to serious illness or death.

In rare cases, measles can lead to a fatal complication known as subacute sclerosing panencephalitis (SSPE).

Everyone has the choice to vaccinate, but it’s vital that decisions are based on accurate medical information.

Authentic Sickle Cell Disease Visual Content for Healthcare, Education, and Publishing

Understanding Sickle Cell Disease

Sickle cell disease (SCD) is one of the world's most common inherited blood disorders, affecting millions of people globally. In the United States, approximately 100,000 individuals live with the disease, with sickle cell disease occurring in about 1 in 365 Black or African American births. The condition is also prevalent in regions where malaria has historically been common, including sub-Saharan Africa, the Middle East, India, and parts of the Mediterranean.

Stock Image Preview

Caused by a genetic mutation in hemoglobin, sickle cell disease transforms normally flexible red blood cells into rigid, crescent-shaped cells that can block blood flow and reduce oxygen delivery throughout the body. These blockages can lead to severe pain crises, anemia, infections, organ damage, stroke, and other life-threatening complications.

Advances in Treatment and Research

Recent advances in treatment have transformed patient care. New medications, improved supportive therapies, stem cell transplantation, and emerging gene-editing approaches offer hope for improved outcomes and, in some cases, a potential cure. Yet many patients continue to face significant health challenges, disparities in care, and limited access to advanced treatments.

As researchers continue to explore innovative therapies, clear and accurate communication remains essential for patients, healthcare professionals, educators, and the public.

Psychology in Pictures

About fifty percent more people receive mental health treatment in the US today than twenty years ago. Psychiatric drug use has gradually increased since the 1980’s and the phrase ‘mental health’ has been used to solve problems as diverse as homicides and depression.

While its origins can be traced back to ancient times, modern psychology begins with Sigmund Freud attempting to understand the subconscious with his famous concepts of the id, ego and superego.

Psychology stock image and video gallery

Following him, Jean Piaget created his own stages of human development and discovered the milestone of object permanence among young children. Pavlov began behaviorism with his famous experiments with dogs.

The'“midlife crisis” appeared first in Carl Jung’s theory of archetypes connecting human experience with ideal structures called archetypes present in the myths of cultures all around the world.

With the rise of modern medicine, psychiatric drugs became widely used in the 20th century. Today 1 in 6 Americans use drugs to treat mental disorders ranging from ADD to bipolar disorder. Anti-depressant use has increased, showing some effectiveness among people with severe depression. Other patients may be affected by the “placebo effect” or the belief that something is working when it is not, adding yet another feature to the world of psychology.

As the study of the mind grows, photographers and illustrators are coming up with new ways of representing it with images.

Myasthenia Gravis, an Autoimmune Disease

Myasthenia Gravis is a rare disease - fewer than 200,000 cases per year in the United States.

GALLERY OF MEDICAL ILLUSTRATIONS OF MYASTHENIA GRAVIS

It is one of the numerous autoimmune diseases. There is no cure, but medications or surgery may help with the condition. The symptoms may last a year or a lifetime.

Visually obvious symptoms are a partial or full paralysis of the face. usually on one side. Droopy eyelids, lack of control of the eye, drooping mouth and lips. Additional common symptoms include weakness of arm or leg muscles, double vision, and difficulties with speech, chewing, swallowing, and breathing.

The cause is a malfunction of the nervous system. Often antibodies block the proper communication in the nervous system.

Experts believe the thymus gland is the source of these antibodies. People with Myasthenia gravis often have an enlarged thymus gland. Fatigue, stress, illness, surgery, and other factors play a role in the onset of symptoms.

In severe cases, the person may need assistance eating or breathing. If detected early, most people can regain enough strength to lead normal or almost normal lives.
