Lung cancer cells, shown in green, growing in a mouse heart

Cancer Is Somehow Rare in the Heart. Turns Out, the Organ’s Rhythmic Beat Might Keep the Disease at Bay, a Mouse Study Finds

Less than 1 percent of cancers start in the heart, and disease that begins elsewhere seldom spreads to the blood-pumping organ. New research suggests mechanical force might have a protective role

An illustration of lymphocytes, or white blood cells in the immune system, which include T cells and other disease-fighting cells

You’ve Been Told to ‘Feed a Cold.’ Turns Out, Eating May Truly Boost Your Immune System Cells, According to a New Study

T cells, which target infection and disease, can become more effective after a meal. The finding might help improve cancer-fighting therapies and optimize our response to vaccines

The A.I. model outperformed two doctors when presented with data from dozens of real E.R. patients.

A.I. Outperformed Doctors at Diagnosing Real-World E.R. Patients in a New Study. That Doesn’t Mean Computers Will Replace Clinicians

One of OpenAI’s large language models did better than physicians in several experiments, hinting that A.I.-assisted emergency medical care could be around the corner

Two Athletes Smashed a Marathon Milestone, Running 26.2 Miles in Under Two Hours. Here’s the Science Behind Their Achievements

An intense training regimen, good weather conditions, physiology and lightweight shoes probably played a role in their astounding performances during the London Marathon on Sunday

The Tees Transporter Bridge was a feat of engineering but has been closed due to structural concerns since 2019.

These Are the Top Ten ‘Endangered’ Buildings and Bridges in England and Wales—and They Tell Us a Lot About Life in the Victorian Era

Structures remaining from the height of the British Empire reveal changing economic, medical and education trends from the 1800s and early 1900s. But their legacy is at risk as they fall into disrepair

Newborns usually go through tests to determine whether they have hearing problems. Undiagnosed issues can delay developmental milestones.

The FDA Approves the First-Ever Gene Therapy for Deafness, Which Aims to Restore Hearing in Kids With a Rare Inherited Condition

The agency’s decision is based on results from a clinical trial in which the treatment improved hearing in 80 percent of the pediatric participants. However, Deaf community advocates worry about the push to cure hearing loss

Some cancer patients ring a bell to signal the end of their treatment and their return to normal life. But many would benefit from specialized long-term medical care to manage the ongoing effects of the disease and its treatments.

Cancer Survivors Are Living Longer but Still Have Complex Needs. That’s Why Doctors and Advocates Want Post-Treatment Care Plans

Survivors have a heightened risk of developing cardiovascular disease, pain, insomnia, psychosocial distress and new cancers. Many, patient advocates say, are not receiving adequate long-term care

More than 50 million people suffer from epilepsy around the world, making it one of the most common and severe neurological disorders globally.

These Young Innovators Have Created a ‘Fitbit’ to Predict Epileptic Seizures

Truman Pierson and Christopher Fitz are developing behind-the-ear EEG patches and an accompanying app that issues an alert if the user is at high risk for a seizure in the next hour

Scientists now think humans settled South America in three waves.

A New Big Database of DNA From Indigenous Americans Shakes Up Scientists’ Theories About Human Settlement of South America

Genomic data provides evidence for a previously unknown wave of migration, with Indigenous groups living in central and southern Mexico spreading into South America and the Caribbean starting around 1,300 years ago

The federal government is reclassifying medical marijuana as a less dangerous drug.

State-Licensed Medical Marijuana Has Been Reclassified as a Less-Dangerous Drug. Here’s What That Means

The move should make it easier for researchers to study the substance and give tax breaks to licensed medical marijuana dealers

The researchers studied neural activity in 16 participants with epilepsy who had electrodes in their brains.

We Use Many of the Same Brain Cells to See and to Imagine Objects, a Study Suggests. The Findings Provide a New Window Into Memory

While past research has hinted at an overlap in relevant brain regions, the new work drills down to the cellular level. The discovery could help improve treatments for memory disorders, such as dementia, and certain psychiatric conditions, like schizophrenia

The McDougall Creek wildfire burns in the hills of British Columbia, Canada, on August 17, 2023. Evacuation orders were put in place for areas near Kelowna, as the fire threatened the city of around 150,000.

Ancient Humans Mastered Fire. Now, Burning Fossil Fuels and Blazing Landscapes Threaten to ‘Undo the World’

Intensifying wildfires across the continent are spewing air pollution, putting human health at risk, particularly Americans living with chronic illnesses

The hallucinogenic mushroom Psilocybe pelliculosa, which contains psilocybin

How Do Different Psychedelics Affect the Brain? Scientists Analyzed More Than 500 Neural Scans to Find Out

A new study suggests that four psychoactive compounds work in surprisingly similar ways, and that they break down the separation between how we think internally and how we perceive the outside world

The clitoris is larger than most people think, and much of the organ is internal.

Scientists Just Made the Most Complete Map of the Clitoris’s Sensory Nerve Network. Here’s What They Found

Cultural taboos around female sexuality have hindered research on the organ. But a new study provides pivotal insights that can inform important surgeries and health care

Traffic fatalities increased by about 15 percent on major album release days, according to a new study.

On Major Music Release Days, Stay Extra Vigilant While Driving. Car Crash Deaths Seem to Spike When Top Artists Drop New Albums

A new study found a correlation between big album release days and traffic fatalities. While the research can’t prove the new music caused the accidents, the work hints at a major distractor while driving

An artificially colored human B cell, the type of immune cell that caused all three autoimmune diseases in the patient

In a First, This Personalized Cell Therapy Treated Three Life-Threatening Autoimmune Diseases in One Patient

The patient was bedridden and needed daily blood transfusions, and she had tried nine different therapies that didn’t bring lasting effects. So, researchers modified some of her immune cells so they would attack her faulty cells

More than 95 percent of the world’s bergamot oil production is concentrated in Southern Italy’s Calabria region. But harsh conditions driven by climate change threaten that supply.

Earth’s Smells Are Disappearing Because of Climate Change, and It’s a Vast Cultural Loss

A triple threat of pollution, extinction and warming temperatures is altering the way the planet smells. Scientists are only beginning to understand the stakes for humans

Tobacco plants make a lot of the amino acid tryptophan, the basis of many psychoactive compounds.

Scientists Engineered Tobacco Plants to Produce Five Mind-Altering Psychedelic Compounds

The substances have been used by Indigenous peoples for thousands of years, but they’ve recently become popular as possible therapeutics for mental health conditions

Becoming an expert birder might support brain health, according to a new study.

Becoming an Expert Birder Can Reshape Your Brain and Might Help Protect It From Aging, New Research Suggests
