Astronomers have discovered a large reservoir of hot gas in the still-forming galaxy cluster around the Spiderweb galaxy — the most distant detection of such hot gas yet. Galaxy clusters are some of the largest objects known in the Universe and this r…

The largest-yet analysis of ancient DNA in Africa, which includes the first ancient DNA recovered from members of the medieval Swahili civilization, has now broken the stalemate about the extent to which people from outside Africa contributed to Swahil…

Nuclear physicists may have finally pinpointed where in the proton a large fraction of its mass resides. A recent experiment has revealed the radius of the proton’s mass that is generated by the strong force as it glues together the proton’s building b…

Overdose mortality among people age 65 and older quadrupled over 20 years, suggesting the need for greater mental health and substance use disorder policies addressed at curbing the trend.

Antarctic circulation could slow by more than 40 per cent over the next three decades, with significant implications for the oceans and the climate.

The advantages of living in cities for children and adolescents’ healthy growth and development are shrinking across much of the world, according to a new global analysis of trends in child and adolescent height and body mass index (BMI).

The digestive tract of fruit flies remodels itself to accommodate beneficial microbiome species and maintain long-term stability of the gut environment, according to new research.

Everyone is talking about the newest AI and the power of neural networks, forgetting that software is limited by the hardware on which it runs. But it is hardware become ‘the bottleneck.’ New collaborators might change that. They believe that they have…

Being able to withstand hurricane-force winds is the key to a long life for many buildings on the Eastern Seaboard and Gulf Coast of the U.S. Determining the right level of winds to design for is tricky business, but support from artificial intelligenc…

Much like how wind plays a key role in life on Earth by sweeping seeds, pollen and more from one place to another, galactic winds — high-powered streams of charged particles and gases — can change the chemical make-up of the host galaxies they form i…

Researchers have advanced our understanding of the circadian clock, the biological cycle that synchronizes with light-dark exposure. They recently developed a method to study how the circadian clock synchronizes with the environment in real time, revea…

A new mouse study has identified a gene-enzyme interaction that appears to play a key role in how the brain forms memories. The findings provide insights into how PDE inhibitor medications may help diseases like Alzheimer’s.

The McCloud River redband trout, or O. mykiss calisulat, is newly identified as its own distinct subspecies of rainbow trout in a new study. It was named in consultation with the Winnemem Wintu tribe.

In an analysis of over 65,000 infants from Japan, children exposed to pet cats or indoor dogs during fetal development or early infancy tended to have fewer food allergies compared to other children.

A new analysis shows that, compared to similarly high-income European countries, the United States continues to have substantially higher death rates at all but the oldest ages, resulting in more ‘excess deaths,’ and this gap widened during the COVID-1…

Ancient 2m-long amphibians swam like crocodiles long before true crocodiles existed, according to a new study.

Life comes in all shapes in sizes, but some sizes are more popular than others, new research has found. A survey of body sizes of all Earth’s living organisms has uncovered an unexpected pattern. Contrary to what current theories can explain, our plane…

Traces of ancient empires that stretched across Africa remain in the DNA of people living on the continent, reveals a new genetics study.

Deep brain stimulation (DBS) is a promising therapy for treatment-resistant obsessive-compulsive disorder (OCD). A new study has found that mapping neural connections in the brains of OCD patients offers key insights that explain the observed improveme…

Moths are more efficient pollinators at night than day-flying pollinators such as bees, finds new research.
