A study has used advanced genetic and genomic techniques to offer a major step forward in understanding and diagnosing infectious intestinal diseases. The large-scale study analyzed more than 1,000 stool samples from people with diarrheal illness to harness…

Using synchrotron X-ray nanotomography with detailed 3D imaging and in-situ mechanical testing, researchers are peering inside shark skeletons at the nanoscale, revealing a microscopic 'sharkitecture' that helps these ancient apex predators withstand extreme…

Photovoltaic systems are increasingly being installed not only on roofs but also on open land. This does not always meet with citizens' approval. What is known as agrivoltaics (Agri-PV), however, is viewed more favorably, as researchers have now been able to…

Imagine drawing on something as delicate as a living cell -- without damaging it. Researchers have made this groundbreaking discovery using an unexpected combination of tools: frozen ethanol, electron beams and purple-tinted microbes. By advancing a method…

A novel analysis suggests more than 3,500 animal species are threatened by climate change and also sheds light on huge gaps in fully understanding the risk to the animal kingdom.

Humpback whales are not always born in tropical waters, new research has shown -- challenging long-held assumptions about their breeding and migration behaviors, while raising new questions for marine conservation.

The average energy project costs 40% more than expected for construction and takes almost two years longer than planned, finds a new global study. One key insight: The investment risk is highest for nuclear power plant construction and lowest for solar. The…

Historically, most human mpox infections have resulted from zoonotic transmission --m eaning from animals to humans -- and these spillovers have rarely led to human-to-human transmission. But during the 2022 global outbreak, mpox began spreading readily…

Scientists have elucidated the molecular mechanism by which LEM-3 cuts DNA bridges during cytokinesis.

A study has become the first in the world to unravel the immediate effects of a high-fat diet on our gut health.

New research reveals mountain glaciers across the globe will not recover for centuries -- even if human intervention cools the planet back to the 1.5 C limit, having exceeded it.

Underwater or aerial vehicles with dimples like golf balls could be more efficient and maneuverable, a new prototype has demonstrated.

A team was able to show that swimming movements are possible even without a central control unit. This not only explains the behavior of microorganisms, it could also enable nanobots to move in a targeted manner, for example to transport drugs to the right…

Nanoplastics are everywhere. These fragments are so tiny they can accumulate on bacteria and be taken up by plant roots; they're in our food, our water, and our bodies. Scientists don't know the full extent of their impacts on our health, but new research…

Researchers have shown that mice use chemical cues, including odors, to detect the social rank of an unfamiliar mouse and compare it to their own, using this information to determine their behavior.

Animal abduction: Biologists documented five male capuchin monkeys carrying at least eleven different infant howler monkeys -- a behavior never before seen in wild primates. Rise and spread: The sightings were remotely recorded by over 85 camera traps, which…

Newly discovered weapons of bacterial self-defense take different approaches to achieving the same goal: preventing a virus from spreading through the bacterial population.

New research suggests that the negative effects of the ozone hole on the carbon uptake of the Southern Ocean are reversible, but only if greenhouse gas emissions rapidly decrease. The study finds that as the ozone hole heals, its influence on the ocean carbon…

A new study reveals that heat-tolerant symbiotic algae may be essential to saving elkhorn coral (Acropora palmata) -- a foundational species in Caribbean reef ecosystems -- from the devastating impacts of marine heatwaves and coral bleaching.

Researchers have shown in mice that brain cells known as astrocytes are required for a signaling chemical called norepinephrine to modify brain activity, changing the textbook understanding that norepinephrine acts directly on neurons.
