Smaller-bodied ruminants forage primarily for the highest energy intake, while equids -- which tend to be larger -- choose to forage in areas close to surface water, with less attention to forage condition.

While it is well known that fighting over money can lead couples to divorce court, new research finds that differences in risk preferences, especially when it comes to financial matters, are likely a root cause of marital separation.

Positive trends in global education access are expected to decrease dementia prevalence worldwide by 6.2 million cases by the year 2050. Meanwhile, anticipated trends in smoking, high body mass index and high blood sugar are predicted to increase prevalence by nearly the same number: 6.8 million cases.

Researchers have for the first time demonstrated a direct link between the decrease in the Dead Sea's water table, evaporation and land subsidence.

A new study has found plastic accumulation in foods may be underestimated. There is also concern these microplastics will carry potentially harmful bacteria such as E. coli, which are commonly found in coastal waters, up the food chain.

New research has uncovered an essential mechanism coordinating the processes of cell division and adhesion within humans. This discovery has profound potential for advancing understanding of cell adhesion signalling in cancerous tumor progression and metastasis.

For decades, a key brain area has been thought to merely regulate locomotion. Now, a research group has shown that the region is involved in much more than walking, as it contains distinct populations of neurons that control different body movements. The findings could help to improve certain therapies for Parkinson's disease.

Magnetic fields around black holes decay quickly, researchers report. This finding backs up the so-called 'no-hair conjecture' predicted by Einstein's general relativity.

How do you control ice formation on a plane, even when it's in flight? Engineers are developing an approach using ice itself. They created a de-icing method that exploits how frost grows on pillar structures to suspend ice as it forms into a layer that's easier to remove.

In nature, the interaction of molecules at the boundary of different liquids can give rise to new structures. These self-assembling molecules make cell formation possible and are instrumental to the development of all life on Earth. They can also be engineered to perform specific functions -- and now, a team of researchers has leveraged this opportunity to develop a material that could remove...

A new study shows that over the course of five years, patients who had bariatric and metabolic surgery to treat uncontrolled type 2 diabetes reported greater physical health, more energy, less body pain, and less negative effects of diabetes in their daily lives, compared with patients who had medical therapy alone for their diabetes.

The devastating bushfires in Australia had a larger impact on the world's 2020 climate than the pandemic-related lockdowns, as plumes of smoke cooled global temperatures and pushed tropical thunderstorms northward. New research indicates that regional wildfires can have far-reaching climatic effects that are comparable to a major volcanic eruption.

Anyone who has ever failed to throw a beer mat into a hat should take note: physicists have discovered why this task is so difficult. However, their study also suggests how to significantly increase accuracy and range.

A new type of wireless charger can charge multiple devices simultaneously, researchers report. The device transfers energy with 90 percent efficiency within 20-centimeter charging range.

The fruit fly has multiple taste organs throughout its body to detect chemicals, called tastants, that signal whether a food is palatable or harmful. It is still unclear, however, how individual neurons in each taste organ act to control feeding. To explore this question, a team used the fly pharynx as a model to study whether taste information regulates sugar and amino acid consumption at the...

A model using simple changes in microbe growth curves could predict how drug resistance evolves in response to different antibiotic combinations, doses and sequences.

International drilling efforts over the last decades into the seafloor have provided increasing evidence for the existence of an extensive deep biosphere below the seafloor. There, circulating fluids in the sub-seafloor deliver chemical compounds from which energy is produced to fuel microbial life in such deep ecosystems. Our understanding of the role of such chemolithotrophic microbes in the...

A team of scientists has leveraged artificial intelligence to train computers to keep up with the massive amounts of X-ray data taken at the Advanced Photon Source.

In a recent study of Black American women, low levels of vitamin D appeared to be related to increased incidence of COVID-19 infection.

Several forms of public messages can increase vaccination intentions, but messaging that emphasizes personal health benefits has the largest impact.

Subtle differences in perception during late-teen years can predict the development of hallucinations, delusions, and, in some instances, psychosis later in life, according to new research.

Madagascar is renowned for its unique and varied biodiversity, which spans dry grasslands, wet rain forests, mangroves and deserts. This variety, combined with the island's isolation and size, has fostered distinctive assemblages of plants and animals, including the country's famous lemurs and baobab trees.

Hydrogen peroxide reacts with copper to produce hydroxyl radicals with strong antibacterial properties. However, this requires high copper concentrations because two copper atoms have to come close together, which occurs by chance. Now, scientists have engineered a long polymer with copper-containing side units that create regions with locally high copper density, boosting the antibacterial...

Every year, 3.5 million metric tons of sodden diapers end up in landfills.
