Up to half of older adults may have sleep apnea, a condition in which breathing and sleep are briefly interrupted many times a night. A new study shows that this chronic tiredness can have serious implications for road safety.

Scientists describe novel methods for inferring the movement of human brain cells during fetal development by studying healthy adult individuals who have recently passed away from natural causes.

One of the most important molecules in the brain doesn't work quite the way scientists thought it did, according to new work.

A beautiful sunset over the Atlantic off the Florida coast, or an orangey glow in the Texas sky at dusk may be caused by dust from West Africa, according to researchers who are looking at the paths of particulate matter in the skies over the Sahara desert and the semi-arid Sahel.

Fun and games could be a solution to serious problems like preeclampsia and hypertension among pregnant people and holds promise for significant progress, according to a new study. Researchers found that gamification—broadly defined as the use of specially engineered games to stimulate learning and behavioral change—could generate greater levels of exercise in postpartum individuals who...

The new analysis suggests that misinterpretation of archaeological evidence at certain sites in North and South America might be responsible for theories that humans arrived long before 13,000-14,200 years ago.

Researchers have found that the KLF4 gene is reprogrammed at the onset of acute promyelocytic leukaemia (APL), an aggressive type of blood cancer that is responsible for 5-15% of all types of leukemia. Overexpressing KLF4 suppressed the self-renewal traits of cancerous cells and reversed the effects caused by the actions of oncofusion events that cause the disease. The findings pave the way for...

The antibody function known as antibody dependent cellular cytotoxicity (ADCC) and the ADCC sensitivity of HIV strains may influence the transmission of HIV from mother to child during breastfeeding. These data imply that enhancing ADCC, through a vaccine, for example, may not be sufficient to prevent transmission because chronically infected individuals can harbor ADCC-resistant strains. The...

In proof-of-concept experiments, scientists say they have successfully cultivated human muscle stem cells capable of renewing themselves and repairing muscle tissue damage in mice, potentially advancing efforts to treat muscle injuries and muscle-wasting disorders in people.

Two new studies provide insights into what additional limits on abortion care could mean, particularly for those who will have to travel across state lines. Distance to care will increase substantially and access barriers will be inequitable, researchers say.

When U.S. couples have their first child, mothers' earnings still drop substantially relative to fathers', and new research demonstrates the stubborn, decades-old pattern isn't changing despite broad increases in other aspects of gender equality.

A survey of veterinarians in the U.S. and Canada highlights mounting cases of cannabis poisoning among pets and sheds new light on symptoms, treatments, and outcomes.

From 2003 through 2020, as opioid-related mortality in Ontario, Canada increased five-fold, the age distribution also shifted downward -- with rates now peaking for people in their mid-30s -- according to a new study.

Over time, using antidepressants is not associated with significantly better health-related quality of life, compared to people with depression who do not take the drugs, according to a new study.

Stones that were incised with artistic designs around 15,000 years ago have patterns of heat damage which suggests they were carved close to the flickering light of a fire, a new study has found.

New research on mice shows for the first time that the microbes in animals' guts influence what they choose to eat, making substances that prompt cravings for different kinds of foods.

Scientists have demonstrated that molecular robots are able to accomplish cargo delivery by employing a strategy of swarming, achieving a transport efficiency five times greater than that of single robots.

Portable MRI machines, an emerging technology that makes medical imaging accessible even in remote locations, detected ischemic strokes, or strokes caused by clotting, in 90% of patients scanned, according to a new study.

Scientists have used computer model simulations to find that climate change is altering the mechanics of surface ocean circulations, making them become faster and thinner.

Using a newly developed model, astrophysicists present a new theory to explain fast blue optical transients, a new class of transients that has boggled researchers since their discovery in 2018. In the new study, astrophysicists find that FBOTs could result from the actively cooling cocoons that surround jets launched by dying stars.

Palaeontologists have discovered remarkable new evidence that pterosaurs, the flying relatives of dinosaurs, were able to control the color of their feathers using melanin pigments.

Intermediate-mass black holes are notoriously hard to find but a new study indicates there may be some at the center of dense, star clusters located throughout the universe. A study now sheds new light on when and where black holes of about 100-100,000 solar masses could form and how they came into being.

The new cells, which the scientists have dubbed killer innate-like T cells, differ in several notable ways from the conventional target of many immunotherapies.

Researchers have developed global forecasts that can provide up to a year's notice of marine heatwaves, sudden and pronounced increases in ocean temperatures that can dramatically affect ocean ecosystems.
