A new report by artificial intelligence (AI) and foreign policy experts predicts that deepfakes technology is on the brink of being used much more widely, including in targeted military and intelligence operations. The experts make recommendations to security officials and policymakers for how to handle the unsettling new technology, including a call to develop a code of conduct for governments'...

Researchers have developed a new method to look at the cerebellum in detail.

Physicists have once again gained a deeper understanding of the mechanism behind superconductors. This brings researchers one step closer to their goal of developing the foundations for a theory for superconductors that would allow current to flow without resistance and without energy loss. The researchers found that in superconducting copper-oxygen bonds, called cuprates, there must be a very...

A promising approach to control Staphylococcus aureus bacterial colonization in people -- using a probiotic instead of antibiotics -- was safe and highly effective in a Phase 2 clinical trial. The new study found that the probiotic Bacillus subtilis markedly reduced S. aureus colonization in trial participants without harming the gut microbiota, which includes bacteria that can benefit people.

A diverse immune response hinges on naive B cells mingling with high affinity ones in the late-stage germinal center. Whether that helps or hinders, however, depends on the virus.

Tropical forests are crucial for sucking up carbon dioxide from the atmosphere. But they're also subject to intense storms that can cause 'windthrow' -- the uprooting or breaking of trees. A new study finds that more extreme thunderstorms from climate change will likely cause a greater number of large windthrow events in the Amazon, which could impact the rainforest's ability to serve as a carbon...

We've all been there. You made a promise you couldn't keep. Or something came up, and you didn't follow through on what you said you'd do. It turns out children pay attention to what we say when we don't deliver. A new study shows that by the time they reach preschool, kids understand that some reasons for reneging are more defensible than others.

Researchers studied human colon cancer tissue samples and animal models and found that exposure to salmonella was linked with colon cancers that developed earlier and grew larger.

Researchers have found new evidence that vitamin D may be metabolized differently in people with an elevated body mass index (BMI). The study is a new analysis of data from the VITAL trial, a large nationwide clinical trial that investigated whether taking vitamin D or marine omega-3 supplements could reduce the risk of developing cancer, heart disease, or stroke.

Studying wolves at the pack level is important because most previous research has focused on population numbers. This study assessed the effects of human-caused mortality on wolf pack social dynamics, a novel approach of analyzing impacts to species based on their group structure.

A simple nasal spray significantly reduced snoring and breathing difficulties in children and halved the number needing to have their tonsils removed, according to a new study.

Is the inside of a plant cell more like a liquid or a solid? While this may sound like an odd question, new research demonstrates it can be either, depending on how much light you shine on it. Chloroplasts within plant cells constitute an active form of matter that undergoes dramatic phase transitions.

Bees may be at risk from exposure to glyphosate -- an active ingredient in some of the EU's most commonly used weedkillers -- via contaminated wildflower nectar, according to new research. Residues of glyphosate have previously been found in nectar and pollen collected by bees foraging on plants that have been selectively targeted with weedkiller, but this time it has been reported in unsprayed...

Scientists have discovered a rare lead compound (named lead formate) in Rembrandt's masterpiece The Night Watch. This rare discovery provides new insight into 17th-century painting technique and the conservation history of the painting.

Living in a greener environment has an impact on the composition of oligosaccharides in mother's breastmilk, which in turn may affect the infant's health. A study showed that greater diversity and proportion of green environments in the residential area were associated with increased diversity in the composition of the oligosaccharides in breastmilk.

Research into how echidnas might respond to a warming climate has found clever techniques used by the animal to cope with heat, including blowing bubbles to wet its nose tip, with the moisture then evaporating and cooling its blood.

Chemists have developed a tool for noninvasive brain imaging that can help illuminate hard-to-access structures and processes. Their small-molecule dye is the first of its kind that can cross the blood-brain barrier, allowing researchers to differentiate between healthy brain tissue and a glioblastoma tumor in mice.

Aging and related diseases are associated with alterations in oxidative status and low-grade inflammation, as well as a decreased endoplasmic reticulum (ER) unfolded protein response (UPR). UPR is a functional mechanism by which cells attempt to protect themselves against ER stress. Researchers analyzed these proteins in peripheral blood mononuclear cells of elderly subjects and used computer...

Capturing the potential profits and jobs offered by a growing hydrogen industry may need as much innovation in regulatory agencies as it does in the research laboratories, according to new research.

Strict-sounding teachers are worse at inspiring the classroom than their kind colleagues, research has revealed. A ground-breaking psychological study of hundreds of children showed 'controlling sounding voices' didn't gain cooperation from 10-16-year-olds.

Artificial intelligence (AI) may help improve care for patients who show up at the hospital with acute chest pain, according to a new study.

Climate change presents a mismatch for some breeding songbirds, finds a new study using a decade of nestbox data.

Separation leads to a significant but temporary increase in gender inequalities in parent-child time, according to new research.

Accurate linking of an individual's medical records from disparate sources within and between health systems, known as patient matching, plays a critical role in patient safety and quality of care, but has proven difficult to accomplish in the United States, the last developed country without a unique patient identifier. In the U.S., linking patient data is dependent on algorithms designed by...
