Because many different types of cancer cells overexpress programmed death-ligand 1 (PD-L1), this cell surface protein is a major target of cancer immunotherapy.

Meta and Google-owned YouTube were accused Monday of pushing highly addictive apps on children as a landmark social media trial began in earnest in a California court.

A new study conducted at the Gray Faculty of Medical and Health Sciences and the Sylvan Adams Sports Science Institute at Tel Aviv University reveals a clear conclusion: strength (resistance) training is the most effective tool for achieving "high-quality" weight loss, reducing body fat while preserving, and even increasing, muscle mass.

On April 20, 2023, a juvenile great white shark (Carcharodon carcharias) measuring approximately 210 cm and weighing between 80 and 90 kg was incidentally caught by local fishermen off the coast of the eastern peninsula within the Spanish Exclusive Economic Zone.

Health care workers have an intense workload and often experience mental distress during resuscitation and other critical care procedures.

New research led by the University of Michigan is painting a more comprehensive picture of how noise pollution is impacting birds around the world.

Scientists have uncovered new DNA-binding proteins from some of the most extreme environments on Earth and shown that they can improve rapid medical tests for infectious diseases.

Researchers at WashU Medicine have identified a potent pathway that begins in the brain and leads to loss of all body fat without reducing food intake.

Aerobic exercise, such as running, swimming, and dancing, may be most effective for relieving the symptoms of depression and anxiety, finds an overarching (umbrella) review and data synthesis of the available evidence, published online in the British Journal of Sports Medicine.

A Dartmouth study finds that molecular hitchhikers living within bacteria can make their hosts extra resistant to medical treatment by corralling them into tightly packed groups.

If you've ever watched a glass blower at work, you've seen a material behaving in a very special way. As it cools, the viscosity of molten glass increases steadily but gradually, allowing it to be shaped without a mold.

Nearly 30 years ago, researchers began studying the gene Astn1, which encodes the cell adhesion protein astrotactin 1 in mice, and its role in brain development.

Water is made of hydrogen and oxygen, and sometimes these atoms are slightly heavier than usual. These heavier forms are called isotopes.

Progressive multifocal leukoencephalopathy (PML) is a rare but serious brain infection. It gradually destroys brain tissue and often leads to death within a few weeks.

Edward (Ed) Waldner had no idea why he didn't feel well, but he knew he didn't feel like himself. At 55 years of age, he felt exhausted all the time.

First names in Western countries today are more diverse than they were before early modern states evolved. This difference started to emerge in the 17th century in response to a change that took place in the naming system in large parts of Europe and the English-speaking world.

A new international study reveals the unexpected importance of acoustic communication in the evolution of boxfishes. This discovery offers new perspectives on the role of acoustic communication in the evolutionary history of numerous fish groups.

Ehlers–Danlos syndromes (EDS) are inherited conditions that affect the body's connective tissue, which provides strength and support to the skin, joints, and blood vessels.

In a lab-grown cell study focused on potential new treatment targets for halting the spread of most pancreatic cancers, Johns Hopkins Medicine scientists report they have found that a gene called KLF5 (Krueppel-like factor 5) fuels the growth of such spreading tumors, not by acquiring abnormal changes in the cancer cells' DNA code itself, but by altering chemical changes and organization of DNA, or epigenetics, that turns genes on and off.

Researchers at the University of North Carolina at Chapel Hill have uncovered how chronic inflammation disrupts the immune system's ability to heal the body, offering new insight into diseases associated with inflammation such as cancer, diabetes, heart disease, and neurological disorders.

A century ago, the section of U.S. federal law governing public health and welfare was relatively small and loosely connected to the rest of the legal system.

Age-related memory decline and neurodegenerative diseases like Alzheimer's are often thought of as irreversible. But the brain is not static; neurons continually adjust the strength of their connections, a property called "synaptic plasticity," and this flexibility is the basis of memory and learning.

Radiation therapy is highly effective at killing cancer cells, but it often harms healthy skin around the treatment area, a common side effect experienced by up to 95% of cancer patients undergoing treatment.

Neural crest cells are a population of stem cells that invade the embryo in early development. They play a big role in what you look like: the pigments of your eyes, of your skin, and the bone structure of your face are all neural crests.

When food is scarce, stress hormones direct the immune system to operate in "low power" mode to preserve immune function while conserving energy, according to researchers at Weill Cornell Medicine.
