Billions of years ago, water flowed on the surface of Mars. But scientists have an incomplete picture of how the Red Planet’s water cycle worked. That could soon change after two graduate…

The largest sample of galaxy groups ever detected has been presented by a team of international astronomers using data from the James Webb Space telescope (JWST) in an area of the sky…

Astronomers have discovered nearly 100 examples of massive black holes shredding and devouring stars, almost all of them where you’d expect to find massive black holes: in the star-dense cores of massive…

A new study published in the journal Coral Reefs reveals that heat-tolerant symbiotic algae may be essential to saving elkhorn coral (Acropora palmata) — a foundational species in Caribbean reef ecosystems —…

Wearable technologies are revolutionizing health care, but design limitations in adhesive-based personal monitors have kept them from meeting their full potential. A new University of Arizona study, published in Nature Communications, describes…

Every living creature on Earth needs to protect itself from things that would do it harm. Bacteria are no different. And despite their relative simplicity, they deploy remarkably savvy defensive strategies against…

Researchers at Washington University School of Medicine in St. Louis have upended decades-old dogma of how connections between brain cells are rearranged during states of heightened vigilance or attention. The team found…

Around the world, 20 percent of children are not fully immunized, leading to 1.5 million child deaths each year from diseases that are preventable by vaccination. About half of those underimmunized children…

An often-ignored type of cell in the brain plays a dynamic and surprisingly complex role in our ability to process information, according to new research from Oregon Health & Science University. The…

It started as a low, haunting roar building in the distance. It grew into a deafening thunder that drowned out all else. The sky turned an unnatural shade of green, then black….

A transient ischemic attack, also known as a mini-stroke, is typically defined as a temporary blockage of blood flow to the brain that causes symptoms that go away within a day, but…

With coral reefs in crisis due to climate change, scientists have engineered a bio-ink that could help promote coral larvae settlement and restore these underwater ecosystems before it’s too late. In a…

Biologists and chemists have a new programming language to uncover previously unknown environmental pollutants at breakneck speed — without requiring them to code. By making it easier to search massive chemical datasets,…

About 15 per cent of all couples of reproductive age are involuntarily childless. A major reason why so many need assisted reproduction is that nowadays more and more people are putting off…

Flamingos standing serenely in a shallow alkaline lake with heads submerged may seem to be placidly feeding, but there’s a lot going on under the surface. Through studies of Chilean flamingos in…

From a small California winery to a large-scale energy project in China, floating photovoltaics — or “floatovoltaics” — are gaining in popularity. Commonly installed over artificial water bodies, from irrigation ponds and…

Millions of kilometres of rivers around the world are carrying antibiotic pollution at levels high enough to promote drug resistance and harm aquatic life, a McGill University-led study warns. Published in PNAS…

Researchers at McGill University, in collaboration with Polytechnique Montréal, pioneered a new way to create hydrogels using ultrasound, eliminating the need for toxic chemical initiators. This breakthrough offers a faster, cleaner and…

New research led by Irish scientists has uncovered how lipid-rich fluid in the abdomen, known as ascites, plays a central role in weakening the body’s immune response in advanced ovarian cancer. The…

For the first time, scientists have discovered fossil evidence of an endangered, living tropical tree species. The unprecedented find was made in Brunei, a country on the large island of Borneo, and…

Chimpanzees are capable of complex communication: The human capacity for language may not be as unique as previously thought. Chimpanzees have a complex communication system that allows them to combine calls to…

MIT engineers are getting in on the robotic ping pong game with a powerful, lightweight design that returns shots with high-speed precision. The new table tennis bot comprises a multijointed robotic arm…

Imagine if doctors could precisely print miniature capsules capable of delivering cells needed for tissue repair exactly where they are needed inside a beating heart. A team of scientists led by Caltech…
