Human 'Brain Cell Atlas' Brings New Insight Into Brain Health, Illness

After a massive five-year effort, researchers have unveiled an “atlas” that gives an unprecedented look at the intricacies of the human brain.

The atlas, which will be available to researchers everywhere, can be seen as similar to the atlases we all know: a book of maps.

But this one catalogues human br...

Scientists Discover Secrets of the Cat's Purr

Anyone with a cat knows the calm, low rumble of purring, but how does such a small animal make such a low sound?

New research suggests it boils down to a pad embedded in feline vocal cord folds.

That's different than previously thought, which was that purring happened through a special mechanism, with cyclical contraction and relaxation of the muscles in the vocal folds within the ...

Music Lovers' Physiology 'Synchronizes' at Classical Music Concerts

New research suggests that concert goers may synchronize their breathing and more as they listen to the intricacies of a classical symphony performance.

Previous studies have shown that music may be able to induce synchronization in listeners, but the authors of this study said there has been little investigation into whether concert audiences actually become synchronized.

This new ...

Exercise Can Preserve Astronauts' Heart Health on Long Space Flights

Extensive exercise regimens are keeping astronauts healthy and protecting their hearts during extended space missions, new research finds.

A study from scientists at UT Southwestern Medical Center in Dallas found no loss of heart mass or output, and no loss of function in the heart's ventricles, during flights that can last up to six months.

The findings could have implications...

Growing Up Poor May Rewire a Child's Brain: Study

Growing up in poverty may harm the structural wiring of a child's brain, a new study claims.

Researchers from Washington University School of Medicine in St. Louis found a link between both neighborhood and household poverty and the brain's white matter tracts. These let the brain communicate between its regions and are important for processing information.

“White matter integrity...

Space Travel Might Weaken Immune System

Space travel appears to weaken astronauts' immune systems, and researchers believe changes in gene expression are the culprit.

These immune deficits aren't permanent. They disappear when back on Earth, often within weeks, according to new research published June 22 in Frontiers in Immunology.

“Here we show that the expression of many genes rel...

Long Space Flights Could Take Toll on Astronauts' Brains

Astronauts spending six months or longer in space should stretch their time between trips to three years, warns new research on the impact of space travel on the brain.

To study this, researchers examined the brain scans of 30 astronauts, looking at scans that depicted their brains both before and after their missions.

The research team included missions that were two weeks long, si...

You May Have Neanderthals to Thank for Your Nose

The influence of Neanderthals is evident right in the center of the faces of modern humans.

New research finds that genetic material inherited from Neanderthals affects nose shape. A particular gene made the nose taller from top to bottom.

This may have been necessary as ancient humans adapted to colder climates.

“In the last 15 years since the Neanderthal genome has been s...

Concussion's Effect on Brain Can Last 6 Months or More

A significant number of patients take far longer to recover from a concussion than expected, and they may not be getting the care they need, according to a new study.

Researchers from the United Kingdom who studied concussion patients found that almost half had changes in how regions of the brain communicate with each other. This may cause long-term symptoms, including fatigue, and impair...

Digestive Organs Vary Widely Between People, Study Finds

People are often reminded that they are their own unique person — and a new study says that's particularly true of the digestive tract.

Dissections of a few dozen deceased individuals revealed striking differences in gastrointestinal anatomy, even among a small group of people.

Some livers were larger, some intestines and colons were longer. Crucial discrepancies were observed bet...

How Round Is Your Heart? It Might Matter for Health

Assessing heart roundness may be a new way to diagnose cardiovascular conditions, new research suggests.

While doctors now use measures like heart chamber size and systolic function to diagnose and monitor cardiomyopathy and other related heart issues, cardiac sphericity (how round the heart is) may be another good tool.

“Roundness of the heart isn't necessarily the problem per se...

Stranded Dolphins' Brains Show Alzheimer's-Like Changes

Groups of whales, dolphins and porpoises are regularly stranded in shallow waters around the coasts of the United Kingdom.

Researchers wanted to understand why, so they studied the brains of 22 toothed whales — or "odontocetes" — that were stranded in Scottish coastal waters.

The study includ...

People Are Still Evolving, Creating New Genes

Humans have continued to evolve after splitting from chimpanzee ancestors nearly 7 million years ago, according to a new study that found 155 new genes unique to humans that suddenly arose from tiny sections of DNA.

Some of the new genes date back to the ancient origin of mammals, according to the researchers. They suspect a few of these “microgenes” have links to hum...

Kidney Disease Is Tougher on Men Than Women, and Researchers Now Know Why

Women tend to be better able than men to recover from kidney injury, but why?

Apparently women have an advantage at the molecular level that protects them from a form of cell death that occurs in injured kidneys, a new study in mice has discovered.

“Kidney disease afflicts more than 850 million people worldwide every year, so it's important to understand why female kidneys are mor...

Could Your Blood Type Raise Your Odds for Stroke?

The risk of suffering a stroke at an early age may depend partly on a person's blood type, a large study suggests.

When it comes to the risk of ischemic stroke — the kind caused by a blood clot — studies have hinted that blood type plays a ...

Want That Pill to Work Fast? Your Body Position Matters

If you need to take a pill, you might want to take it lying down -- on your right side, that is.

Researchers studying how body positioning affects the absorption of pills found that one taken when a person was lying on the right side speeded pills to the deepest part of the stomach. That pill could then dissolve 2.3 times faster than if the person was upright.

"We were very surprise...

Pig Hearts Successfully Transplanted Into 2 Brain-Dead Patients

Genetically altered pig hearts could soon become a viable transplantation alternative for people with life-threatening heart disease, new experiments show.

    No 'Fall Back'? Sleep Experts Argue Against Daylight Standard Time

    Most folks groan when the time comes to either "spring forward" or "fall back" an hour, with the waxing and waning of daylight saving time.

    But that one-hour time shift -- which occurs at 2 a.m. Sunday -- is more than just a minor annoyance, sleep experts say.

    Research has shown that deliberately messing with our internal clock twice a year increases our risk of accident, illness an...

    Gender-Affirming Mastectomies Give Boost to Patients' Mental Health

    Gender-affirming breast removal (mastectomy) can greatly enhance a patients' mental well-being, a new study finds.

    Gender-affirming mastectomy is the most common type of gender-confirming surgery, but there's "not a lot of information out there about how exactly these types of surgeries help people," said study co-author Dr. Megan Lane. She is a plastic surgery resident at Michigan Medic...

    Shape, Size of Brain Arteries May Predict Stroke Risk

    The size and shape of the blood vessels in your brain may help predict your risk of an often-fatal type of stroke, called an aneurysm, a new study finds.

    "It is something of a treacherous subject to navigate," said lead researcher Michael Fe...

    Could Your Child Have a Heart Defect? Know the Warning Signs

    Heart defects are often - but not always - detected at birth, so it's important to pay attention when a child gets dizzy, passes out or says her heart is "beeping."

    These and other warning signs, such as an apparent change in fitness, shouldn't be overlooked, an expert says.

    Evaluating a child who has these symptoms is important to ensure nothing is missed that could become li...

    Some Folks Do Age Slower Than Others

    People really do vary in how fast they age, and the divergence starts in young adulthood, a new study suggests.

    The researchers found that by the tender age of 45, people with a faster pace of "biological aging" were more likely to feel, function and look far older than they actually were. And that relative sprint toward old age began in their 20s.

    The findings, the study authors sa...

    Scientists Create First Lab Model of Human 'Pre-Embryo' for Research Purposes

    Research into miscarriages, infertility and birth defects is now primed to undergo revolutionary advances, thanks to the creation in the lab of an early stage of human embryos by two separate international teams of scientists.

    Women's Menstrual Cycles Tied to Moon's Phases: Study

    There have long been theories that women's menstrual cycles align with the moon, and now a new study suggests there's some truth to that.

    Using years of records kept by 22 women, researchers found that for many, menstrual cycles "intermittently" synced up with the phases of the moon.

    The link happened only about one-quarter of the time for women aged 35 or younger, and just 9% of th...

    Discovery Could Explain Why Black Americans More Prone to Colon Cancer

    New research reveals why Black Americans might be more vulnerable to colon cancer than white people are.

    The researchers examined age-related "epigenetic" changes in colon tissue. These changes affect how genes work.

    The investigators found that in both Black and white people, one side of the colon ages biologically faster than the other. But the side that ages faster is different, ...

    Human Biology Appears to Have Two Seasons, Not Four: Study

    The human body apparently disagrees with Mother Nature on how many seasons there are.

    Instead of four seasons, human biology appears to have two, according to a team of Stanford University researchers.

    "We're taught that the four seasons -- winter, spring, summer and fall -- are broken into roughly equal parts throughout the year, and I thought, 'Well, who says?' " said Mich...

    In Rare Case, COVID-19 Test Caused Spinal Fluid Leak

    Doctors stress that it's a very rare occurrence, but one woman's pre-surgery COVID-19 nasal swab test appears to have triggered a release of cerebrospinal fluid into her upper nasal cavities.

    The incident was tied to a tiny gap in the bones of the woman's skull -- an encephalocele.

    "The [COVID-19 test] swab itself did not result in a violation of the bony skull base, but rat...

    Even If Hips, Legs Slim Down, Belly Fat Remains a Health Danger

    Gaining weight around your mid-section may be the makings of much more than a wardrobe crisis: It may also signal the start of a serious health crisis.

    So warns a team of Canadian and Iranian researchers who conducted an extensive review of 72 studies involving more than 2.5 million patients from all over the globe.

    "We found that excess fat in the abdomen -- called central...

    Do Fatter Legs Mean Lower Blood Pressure?

    People with fatter legs appear less likely to have high blood pressure, new research suggests.

    The researchers suspect that measuring leg fat could help guide blood pressure prevention efforts. Those with bigger legs may not need to worry as much about high blood pressure -- a contributor to heart attack and stroke.

    "Distribution of fat matters. Even though we think that f...

    A New 'Spin' on How Sperm Swim

    If you ever had a sex-ed class in school, you have probably seen a visual of sperm swimming with a wagging tail. Now, high-tech tools have shattered that view of how sperm move.

    More than 300 years ago, a Dutch scientist used an early microscope to observe human sperm in motion. He saw that they appeared to swim using a tail that moved from one side to the other.

    But scient...
