Sarcopenia, a decline in skeletal muscle in older people, contributes to loss of independence.

Mathematician Sir Michael Atiyah claimed he solved the "most important open problem" in maths, the Riemann hypothesis. At a lecture in Germany on Monday he...

Americans under the age of 45 have found a novel way to rebel against their elders: They’re staying married. New data show younger couples are approaching relationships very differently from baby boomers, who married young, divorced, remarried and so on.

More people are working for ride-sharing and delivery companies but on average they’re making less.

Millions of Americans struggle with substance abuse and tens of thousands die each year, according to the American Society of Addiction Medicine. Though treating addiction has become a vast (and at times abusive) industry, the underlying causes of drug or alcohol dependency—and how to successfully treat these debilitating conditions—are still poorly understood by science. Now, researchers think they’ve found the germ of an answer in our genetic past.

Starting schools before 8:30 a.m. shows a tragic disregard for both the mental health of children and for science.

Ahmet Hergune was killed during the conflict between Greek Cypriots and Turkish Cypriots in 1974

Scientists say they have taken a potentially important — and possibly controversial — step toward creating human eggs in a lab dish. A team of Japanese scientists turned human blood cells into stem cells, which they then transformed into very immature human eggs. The eggs are far too immature to be fertilized or make a baby. And much more research would be needed to create eggs that could be useful — and safe — for human reproduction.

New research from USC has uncovered a previously unknown genetic risk factor for Alzheimer’s disease and related dementias. The study provides insights on how these conditions, and other diseases of aging, might one day be treated and prevented. The research from the Cohen Lab at the USC Leonard Davis School of Gerontology sheds new light on the protective role of a naturally occurring mitochondrial peptide, known as humanin.

Sufficient sleep has been proven to help keep the body healthy and the mind sharp. But it’s not just an issue of logging at least seven hours of Z’s. A new study on sleep patterns suggests that a regular bedtime and wake time are just as important for heart and metabolic health among older adults. In a study of 1,978 older adults published online Sept. 21 by the journal Scientific Reports, researchers at Duke Health and the Duke Clinical Research Institute found people with...

After falling past the event horizon — the point of no return — nothing can escape a black hole. While the depths of black holes may forever remain a mystery, astronomers can observe the regions around them. In a paper published September 3 in the Monthly Notices of the Royal Astronomical Society, a team of researchers reported, for the first time, spotting a clump of matter falling directly into a distant black hole at nearly one-third the speed of light.

'There haven’t been any new drugs last 15 years, so it’s very promising to have uncovered a reason why some of that research may have failed'

A new study shows that the breakdown of water molecules trapped in ancient Martian rocks likely produced enough chemical energy to sustain microorganisms for hundreds of millions of years beneath the Red Planet’s surface.

Obesity is set to overtake smoking as the biggest preventable cause of cancer in UK women by 2043, a Cancer Research UK report predicts. Currently, 12% of cancers in women are linked to smoking, and 7% to being overweight and obese. But with the number of smokers falling and obesity rates projected to rise, the charity estimates that gap will disappear in 25 years time. The figures assume that current trends will continue.

Oval-shaped Dickinsonia lifeform existed at least 20m years before the ‘Cambrian explosion’ of animal life

Acute respiratory tract infections (ARTIs), including the common cold, influenza, and pneumonia, are quite common in children. On average, kids experience between three and six of these infections every year. Most cases resolve without any serious harm, but tens of millions of these infections require hospitalization each year across the globe. In fact, ARTIs account for a quarter of deaths in children under age five, with pneumonia by far inflicting the most casualties.

Did the octopus evolve its unique intelligence by playing fast and free with the genetic code? Elizabeth Finkel investigates.

Salvia is best known as somewhat of a meme—the goofy, over-the-counter psychedelic prevalent in head shops, notorious for its uncomfortable, short-lived hallucinogenic trip. Pretty much harmless, but a way that many young psychonauts get their toes wet. But the herb Salvia divinorum carries great cultural significance in some parts of the world, and research into …

Physicists took a deeper look at the Leidenfrost effect, which you’ve likely experienced when you’ve dripped water into a pan to test its temperature.

Mammals are unique in many ways. We're warm-blooded and agile in comparison with our reptilian relatives. But a new study, funded by the National Science Foundation (NSF) and led by Harvard University researchers Stephanie Pierce and Katrina Jones, suggests we're unique in one more way -- the makeup of our spines. The researchers describe their finding in a paper published this week in the journal Science.

A study in mice hints at a new approach for thwarting neurodegenerative diseases—but many questions remain.

The evidence is in. A mysterious creature that lived on Earth over half a billion years ago has now been proven an animal. A fossil from 558 million years ago was so well preserved, it still had fat molecules.

The sociologist Margaret Hagerman spent two years embedded in upper-middle-class white households, listening in on conversations about race. By Joe Pinsker. (Sept. 4, 2018)

New sorting algorithm yields more robust, replicable results than other methods.

​Diets like intermittent fasting are proving wildly popular for their rapid weight-loss effects, but scientists are also starting to uncover how they might benefit the body in other ways. A molecule produced during fasting has now been found to apply the brakes to aging of the vascular system.

The first simple blood test to identify your body’s precise internal time clock as compared to the external time has been developed by Northwestern Medicine scientists. The test, TimeSignature – which requires only two blood draws – can tell physicians and researchers the time in your body despite the time in the external world. For instance, even if it’s 8 a.m. in the external world, it might be 6 a.m. in your body.

New study: Ingesting even a single piece of plastic exposes sea turtles to a 20% chance of death.

Scientists agree that the story of the universe began 13.8 billion years ago, when everything — all the matter and energy and even space itself — emerged from the extraordinarily hot, dense cauldron known as the Big Bang. But ask a scientist what came before that first moment, and you’re likely to get a shrug. To many, thinking about a time before the beginning of time makes no sense.

Someday doctors may prescribe sugar pills for certain chronic pain patients based on their brain anatomy and psychology. And the pills will reduce their pain as effectively as any powerful drug on the market, according to new research. Northwestern Medicine scientists have shown they can reliably predict which chronic pain patients will respond to a sugar placebo pill based on the patients’ brain anatomy and psychological characteristics.

Wasps are being wiped out as quickly as bees - and their disappearance will be just as disastrous, according to new research. But the plight of wasps is going under the radar compared to that of their close cousins - because of their unpopularity. Nature's unloved insects are best known for ruining picnics - and leaving a painful sting when we try to swat them away.

History and literature are filled with warnings about the danger of seeking eternal life. But in the latest episode of Crazy/Genius, some scientists say that a dramatic expansion of human lifespans is within reach.

In a few idyllic parts of Queensland grows the idiot fruit, a tall tree with intricate flowers and some of the largest seeds in Australia.

A new paper has taken a ingenious route towards treating cocaine addicted mice – by developing a CRISPR-powered skin grafts that produce an anti-cocaine enzyme.

We love to categorize ourselves and others into personality types. Maybe you’re a “Type A.” Or maybe the Meyers-Briggs Type Indicator, versions of which many have taken on Facebook, labels you a “Protector” (ISFJ). But how distinct are these types? Is everyone clearly Type A or Type B, with no one in between? Or do people fall on a spectrum? If there’s a spectrum, are there two clumps with a few people between, or one clump in the middle with a few people at the extremes?
