Reprogramming the Body to Fight Cancer: The Promise of CAR T-Cell Therapy

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

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

First, doctors collect a sample of your blood 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

Unlike chemotherapy, which can damage healthy cells along with cancerous ones, CAR T-cell therapy is designed to target only cancer cells. This precision reduces collateral damage and can lead to more effective outcomes.

The therapy has shown particular success in treating blood cancers such as leukemia and lymphoma—especially in patients who have not responded to standard treatments.

Long-Term Impact

One of the most exciting aspects of CAR T-cell therapy is its potential durability. Many patients experience remission lasting three to four years, with some cases extending up to nine years and beyond.

With advances in CRISPR, these therapies are becoming increasingly precise and effective. Researchers are now expanding their use beyond blood cancers to target solid tumors such as breast, prostate, and sarcomas, with ongoing development for challenging conditions including glioblastoma, melanoma, liver cancers, and even certain autoimmune diseases.

A New Era in Cancer Treatment

CAR T-cell therapy represents a fundamental shift in how we approach cancer—from broadly attacking the disease to precisely engineering the body’s own defenses.

What was once rapidly fatal can now, in some cases, be managed for years—or even decades.

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.

Explore the Story Through Visual History

At Science Source, we offer a vast collection of scientific, medical, and historical stock imagery that brings stories like this to life.

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.

Sickle cell anemia is the most common inherited blood disorder worldwide. In the United States, it primarily affects people of African descent, with 1 in 365 African American births impacted. Globally, the disease is more prevalent in regions such as sub-Saharan Africa, the Middle East, and South Asia, where malaria is endemic.

Despite advances in treatment—such as bone marrow and stem cell transplants and promising gene therapies—access to a cure remains limited. Patients often face lifelong complications, including chronic pain, anemia, frequent infections, stroke, and even leukemia. Clear, accurate communication about the dangers and treatments of this disease is more important than ever.

At Science Source, we provide authentic medical stock photography, illustrations, and video content—never AI-generated. Our robust captions and accurate metadata make our collection of medical scans, micrographs, and educational visuals ideal for use in publishing, healthcare communication, and educational projects.

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.

Monkeypox Now in the United States, the UK and Europe

The world is just beginning to feel the Coronavirus pandemic loosen it grip when we have a new disease to be concerned with: Monkeypox.

What is Monkeypox? It is a viral infection - related to smallpox - that was first noticed in 1958 in research monkeys. The Democratic Republic of Congo recorded the first human case in 1970.

GALLERY OF MONKEYPOX STOCK PHOTOS AVAILABLE TO LICENSE

Up until now, only cases appeared in people in or who had traveled from the DRC. who had traveled to the DRC. Now in May of 2022, new cases are coming to light - in people that have no connection to international travel.

In the past human to human transmission was extremely rare. The disease causes a skin rash with multiple large oozing blisters. Transmission could occur with the contact of the body fluids or linens contaminated with these fluids.

Animal transmission could occur through a bite, scratch or eating bush meat.

Scientists are now investigating whether the recent infections were transmitted from one human to another via sexual activity.

On the positive side, there is already a vaccine that is currently available to people who are at high risk of exposure, such as medical workers. And like the Coronavirus the best ways to prevent infection are to avoid contact with an infected person, infected animals, or any materials handled by an infected person or animal.

And wash your hands!

American Heart Month: How the Heart Works

Did you know that your body houses millions of vessels that are circulating blood at this very moment? In fact, if all the blood vessels in the average adult were connected in one line from beginning to end, they would stretch 100,000 miles. The circulatory (or cardiovascular) system carries blood all throughout your body to transport nutrients, allow for essential body functions like breathing, and maintain an overall homeostasis.

Arteries, veins and capillaries are the three different types of blood vessels that make blood circulation possible. Veins transport deoxygenated or waste-rich blood that will eventually be filtered, and arteries carry the filtered, oxygenated blood. Capillaries are the middle man of blood circulation, as they enable the exchange of blood between arteries and veins.

Heart images stock gallery

There are two types of blood circulation: pulmonary and systemic. Pulmonary circulation is the transportation of blood to the lungs so that the blood becomes oxygenated and can return to the heart. This oxygenated blood is then used within systemic circulation.

During systemic circulation, the heart pumps oxygenated blood out to the rest of the body through the arteries. Capillaries deoxygenate the blood by swapping out the oxygen with carbon dioxide, and they then deliver the deoxygenated blood to the veins. The veins carry the deoxygenated blood back to the heart to start the pulmonary cycle over again.

This intricate and elegant system is happening constantly within your body. Without it, you would have no digestive system or immune system, and even your hormones wouldn't be able to be expressed.

American Heart Month is a time for looking after our heart health. Staying healthy, hydrating, and exercising regularly can help ensure your heart stays healthy and everything in the bloodstream is flowing smoothly.

Isaac Newton and Understanding Color

Newton was so devoted to understanding color that he poked himself in the eye one day - on purpose. He hoped to better understand the optics of colors and light.

He eventually figured out a safer and better means. He used a prism.

GALLERY OF IMAGES: ISAAC NEWTON AND OPTICS

In a dark room, he directed a ray of sunlight through a prism and saw that seven colors of light were transmitted out through the other side.

He then passed those through a second prism and saw that they did not divide further. He thus ascertained that white light was made up of seven colors.

POSTERS AND T-SHIRTS OF SIR ISAAC NEWTON

Isaac Newton (December 25, 1642 - March 20, 1727) was an English physicist, mathematician, astronomer, natural philosopher, alchemist, and theologian. His monograph "Philosophiae Naturalis Principia Mathematica", published in 1687, lays the foundations for most of classical mechanics.
