Researchers have discovered that extracts from plants used by the Kwakwaka'wakw First Nations peoples in their traditional botanical medicine practices are able to rescue the function of ion channel proteins carrying mutations that cause human Episodic Ataxia.

Critical insights into why airborne viruses lose their infectivity have been uncovered. The findings reveal how cleaner air kills the virus significantly quicker and why opening a window may be more important than originally thought. The research could shape future mitigation strategies for new viruses.

Researchers detected elevated PFAS levels in the blood of pet dogs and horses from Gray's Creek, N.C. -- including dogs that only drank bottled water.

A team of scientists has observed past episodic intraplate magmatism and corroborated the existence of a partial melt channel at the base of the Cocos Plate. Situated 60 kilometers beneath the Pacific Ocean floor, the magma channel covers more than 100,000 square kilometers, and originated from the Galápagos Plume more than 20 million years ago, supplying melt for multiple magmatic events -- and persisting today.

The face of a 16-year-old woman buried near Cambridge (UK) in the 7th century with an incredibly rare gold and garnet cross (the 'Trumpington Cross') has been reconstructed following analysis of her skull. The striking image is going on public display for the first time on 21st June, with new scientific evidence showing that she moved to England from Central Europe as a young girl, leading to an intriguing change in her diet.

A detailed, high-resolution map of the rusty patched bumble bee's genome has been released, offering new approaches for bringing the native pollinator back from the danger of extinction. Putting together the rusty patched bumble bee genome is part of the Beenome 100 project, a first-of-its-kind effort to create a library of high-quality, highly detailed genome maps of 100 or more diverse bee species found in the United States.

In the face of the biodiversity crisis, and alarming data showing a 69% decline in global animal populations since 1970, researchers are banking on a cool solution to help save species from extinction. Much like egg-freezing is used to preserve human fertility options for a later date, the cryo-freezing of genetic samples taken from animals may play an essential role in curbing species extinctions. A new study sheds light on the immense potential of living cell banks, also known as cryobanks, to contribute to global conservation priorities.

Researchers have demonstrated how carbon dioxide can be captured from industrial processes -- or even directly from the air -- and transformed into clean, sustainable fuels using just the energy from the Sun.

In the age of dinosaurs, many marine reptiles had extremely long necks compared to reptiles today. While it was clearly a successful evolutionary strategy, paleontologists have long suspected that their long-necked bodies made them vulnerable to predators. Now, after almost 200 years of continued research, direct fossil evidence confirms this scenario for the first time in the most graphic way imaginable.

Genome Architecture Mapping captures complex, multi-way interactions in the genome. This is different than the workhorse technique of 3D genomics, which sees mostly two-way contacts, finds a new study.

A team of researchers has developed a new method for controlling lower limb exoskeletons using deep reinforcement learning. The method enables more robust and natural walking control for users of lower limb exoskeletons. "Robust walking control of a lower limb rehabilitation exoskeleton coupled with a musculoskeletal model via deep reinforcement learning" is available open access.

Scientists discover shattered chromosomal fragments are tethered together during cell division before being rearranged; destroying the tether may help prevent cancerous mutations.

A team or researchers reports the first Aging Fly Cell Atlas (AFCA), a detailed characterization of the aging process in 163 distinct cell types in the laboratory fruit fly. Their in-depth analysis revealed that different cell types in the body age differently, each cell type following a process involving cell type-specific patterns. AFCA provides a valuable resource for researchers in the fruit fly and aging communities as a reference to study aging and age-related diseases and to evaluate the success of anti-aging strategies.

When intermittent fasting became all the rage among Hollywood celebrities, skeptics balked at the idea of skipping meals. But new research suggests the celebs might not have been that far off. The review found that a specific type of restricted eating may reduce the chances of developing Type 2 diabetes and improve your overall health. Known as time-restricted eating, this type of fasting means having regular but fewer meals, cutting out late-night snacks and not eating for 12 to 14 hours (often overnight).

Digital modelling of legendary fossil's soft tissue suggests Australopithecus afarensis had powerful leg and pelvic muscles suited to tree dwelling, but knee muscles that allowed fully erect walking.
