New findings significantly alter the prevailing understanding of how marine life influences clouds and may change the way scientists predict how cloud formation responds to changes in the oceans.

Researchers uncover mechanism that underlies the exquisite sensitivity of certain skin surfaces. The analysis, conducted in mice, reveals that the higher sensitivity of certain regions of the skin stems from a greater number of and stronger connections between neurons in these regions and corresponding brain areas that receive signals from them. The findings set the stage for better understanding...

Mechanical engineering researchers have developed a lightweight powered exoskeleton that helps lower-limb amputees walk with much less effort. The device uses motors, microprocessors and advanced algorithms to aid users in walking, much like an e-bike helps riders pedal uphill.

New research has shown how a synthetic self-made fibers can guide molecular movement that can be fueled by light over long distances, a discovery that could pave the way for new ways to use light as a source of sustainable energy.

Scientists have found a way to decode the brain activity associated with individual abstract scientific concepts pertaining to matter and energy, such as fermion or dark matter.

Older adults around the world are more willing to donate to charity than younger people, but will prioritize charitable organizations operating within their own country, new research finds.

The Scandinavian winter swimming culture combines brief dips in cold water with hot sauna sessions -- and now, a study of young men who participate regularly in these polar plunges finds that winter swimming may allow the body to adapt to extreme temperatures. The findings suggest that routinely alternating swims or dips in chilly water with sauna sessions might affect how brown fat, also known as...

A commonly available, FDA-approved oral diuretic pill may be a potential candidate for an Alzheimer's disease treatment for those who are at genetic risk, according to new findings.

People without immunity against COVID-19 were at considerably lower risk of infection and hospitalization as the number of family members with immunity from a previous infection or full vaccination increased, according to a new study from Sweden.

A massive prospective spill from a deserted oil tanker in the Red Sea could lead to catastrophic public health effects in war-torn Yemen and neighboring countries unless urgent action is taken, according to a new study.

Using the world's most powerful radio antenna, scientists have discovered stars unexpectedly blasting out radio waves, possibly indicating the existence of hidden planets.

Events of jaguars predating on and attacking dogs are poorly documented throughout the Americas. Researchers from Mexico and Germany report in detail jaguar attacks on 20 dogs at a tourist site in the Mexican Caribbean. In addition, they describe an initiative proposed by locals as well as national and international NGOs to prevent human-jaguar conflicts due to pet predation.

Fraudulent practices in food production, especially false claims of geographical origin, cause billions of dollars in economic damage every year. Botanists have now developed a model that can be used to determine the origin of food in an efficient and low-cost manner.

A new study, which finds an increased risk of poorer outcomes for the new-borns and symptomatic women with COVID-19, adds further weight to the argument for pregnant women to be vaccinated for the virus.

A new automated numerical scheme is proposed for upper tropospheric cyclones (cutoff lows) and their earlier development stage as troughs (preexisting troughs). The proposed scheme has the capacity of early stage detection and can extract locations with transitions that are as smooth as possible and estimate their intensities, sizes, and even the local background flows behind them in a consistent...

A class of materials that once looked as if it might revolutionize everything from solar cells to frying pans -- but fell out of favor in the early 2000s -- could be poised for commercial resurrection, new findings suggest.

Using cutting-edge cryptographic techniques (multiparty homomorphic encryption), a new platform called FAMHE will act as a game-changer towards precision, personalized medicine.

Researchers have identified molecules in the blood that can indicate impending dementia. Their findings are based on human studies and laboratory experiments. The biomarker is based on measuring levels of so-called microRNAs. According to the study data, microRNAs could potentially also be targets for dementia therapy.
