A toxicologist's guide to poison ivy's itch and bee stings' burning pain: Two examples of nature's chemical warfare

About 49% of people are unaware of one or more vaccines recommended for them. Further, 86% have not received one or more of these vaccines.

Hunger exists on a spectrum. On the one end is food insecurity, where people are forced to adjust to fewer meals. As food becomes scarce, the body consumes its own reserves. The journey from hunger to starvation starts with a drop in energy levels, then the body breaks down fat, then muscle. Eventually, critical organs begin to fail.

Many major cancers, including those of the lung, breast and prostate gland, spread to the bones as they progress. These bone metastases are often debilitating, even deadly. They are also notoriously resistant to all kinds of treatment, including immunotherapy.

A drug already FDA-approved for asthma was found to nearly eliminate life-threatening allergic reactions to food allergens in mice—a breakthrough that could lead to new protection for millions of people living with food allergies, reports a new Northwestern Medicine study.

Talking therapy offered by the NHS for people with depression or anxiety appears to be less effective for people aged 16–24 than those aged 25–65, according to a new study led by UCL researchers.

Americans still get most of their calories from ultra-processed foods, but consumption is trending down among both adults and children, official data showed Thursday.

Recent research shows that lipoedema and its painful, difficult-to-lose fat hurts less when patients are on a low-carb diet.

Imagine hammering a nail into a wall: Your dominant hand swings the hammer while the other holds the nail steady. In a new theory, Cornell psychology scholars propose that everyday tasks like this are responsible for a fundamental aspect of perception in the brain: why one side is specialized to process high-frequency visual information, and the other low frequencies.

Nearly a third of cancer-related deaths are caused by cachexia, a currently incurable metabolic syndrome that involves substantial weight loss, including depletion of muscle mass and body fat. Researchers from the Weizmann Institute of Science and the University of Texas MD Anderson Cancer Center have discovered that one of the reasons for this loss is disrupted communication between the brain and the liver.

Over the past two centuries, vaccines have been critical for preventing infectious diseases. The World Health Organization estimates that vaccination prevents between 3 million and 5 million deaths annually from diseases like diphtheria, tetanus, influenza, measles and, more recently, COVID-19.

Longer, darker lashes are having a moment. For those avoiding the risk or expense of lash extensions, serums can seem like a safer, more affordable option. But not all lash serums are created equal—and some come with hidden side-effects.

Even after more than three decades of global efforts to promote inclusive sexual and reproductive health policies, many women with disabilities in Africa still face serious challenges. Their rights are often overlooked, and they have limited access to contraception and other essential services.

People with type 2 diabetes are up to four times more likely to have heart attacks, strokes, anginas and other coronary heart diseases than healthy people. Therefore, biomarkers that help us understand which individuals are at risk of being affected are needed.

Scientists have developed a new compound that could offer a breakthrough in the global fight against tuberculosis, history's deadliest infectious disease.

The last few weeks of summer, heading into Labor Day weekend, can sometimes mean vacations and driving more miles on the road for all people, including teens.

A new study by researchers at Simon Fraser University is shedding light on how the brain's wiring in early childhood lays the foundation for attention skills—a key step toward characterizing healthy developmental patterns that could help identify young children at risk for attention-related challenges like ADHD.

A team of researchers led by a Brown University cancer biologist found that when they introduced mutated blood cancer cells into mice and tracked them over time, the cancer cells affected not only non-mutated cells, but also the entire blood-forming system.

A new study by the Menzies-led DIABETES Across the LIFECOURSE: Northern Australia Partnership (the Partnership) has identified seven co-designed recommendations for schools to better support Aboriginal and Torres Strait Islander young people living with type 2 diabetes.
