An international research team has pioneered a new technique to identify and characterize atomic-scale defects in hexagonal boron nitride (hBN), a two-dimensional (2D) material often dubbed 'white graphene' for its remarkable properties. This advance could accelerate the development of next-generation electronics and quantum technologies. Read more ›

A research team has used nitrogen isotope analysis to demonstrate that 385 million years old corals from the Eifel and Sauerland regions had symbionts. This finding represents the earliest evidence of photosymbiosis in corals. Photosymbiosis might explain why ancient coral reefs grew to massive sizes despite being in nutrient-poor environments.

Changing precipitation patterns in the Neotropics, one of Earth's most biodiverse regions, could threaten two-thirds of the area's bird species by the year 2100 if climate change goes unchecked, according to research. This would represent a dramatic loss, as the region is home to 30% of all bird species globally. Read more ›

Scientists modeled the number of 'outdoor days' -- with comfortable temperatures for outside activities -- that U.S. regions will experience as climate warms. States in the Southeast will lose a significant number of outdoor days, while the Northwest should see a slight increase. Read more ›

In a study, researchers use neuroimaging methods to examine brain resilience in regions of the brain linked to language and aging. They found that the hippocampus in bilinguals with Alzheimer's disease was noticeably larger than those who were monolingual when matched for age, education, cognitive function and memory, which suggests that there may be some form of brain maintenance related to bilingualism.

A new artificial intelligence-based system can accurately assess the chromosomal status of in vitro-fertilized (IVF) embryos using only time-lapse video images of the embryos and maternal age, according to a new study. Read more ›

Chemists have developed a new theoretical framework for more accurately predicting the behavior of catalysts. The study reveals how conditions such as temperature and pressure can change a catalyst's structure, efficiency, and even the products it makes -- and can potentially be used to control reaction outcomes.

The noses of many mammals, such as dogs, ferrets and cows, feature grooves forming a multitude of polygons. A team has analyzed in detail how these patterns form in the embryo using 3D imaging techniques and computer simulations. The researchers discovered that differential growth of the skin tissue layers leads to the formation of domes, which are mechanically supported by the underlying blood vessels. This work describes for the first... Read more ›

Whether we're staring at our phones, the page of a book, or the person across the table, the objects of our focus never stand in isolation; there are always other objects or people in our field of vision. How that visual 'clutter' affects visual processing in the brain, however, is not well understood. In a study, researchers show that this clutter alters how information flows in the brain, as does...

Disc golf is a sport growing in popularity, but there hasn't been much research into the best techniques -- until now. Researchers and disc golf enthusiasts have determined the best thumb position on a disc to maximize angular and translational speeds. Read more ›

Flathead catfish -- native to the Mississippi River basin -- were first detected in the Susquehanna River in Pennsylvania in 2002, according to the U.S. Geological Survey. In the two decades since then, the invasive species has spread throughout the river basin. The impact of the large predator on the waterway's food webs and ecology was unknown, but now a research team is beginning to understand what Susquehanna flatheads are... Read more ›

The emergence of quantum entanglement is one of the fastest processes in nature. Scientists show that using special tricks, this can be investigated on an attosecond scale. Scientists have managed to analyze ulrafast processes which up until now were considered to be 'instantaneous': When a laser pulse hits an atom with two electrons, one electron may be ripped out of the atom, while the other electron stays close to the...

Polar bears in some parts of the high Arctic are developing ice buildup and related injuries to their feet. The changes appear to be an unexpected consequence of climate change, related to changing conditions in a warming Arctic. Read more ›

Expanding access to new, highly effective weight-loss medications could prevent more than 40,000 deaths a year in the United States, according to a study. The findings highlight the critical need to remove existing barriers that are hindering people's access to effective weight loss treatments and impeding public health efforts to address the national obesity crisis, the researchers said. According to the U.S. Centers for Disease Control and Prevention, about 74%... Read more ›

Researchers describe the full molecular structure of the phage DEV. DEV infects and lyses Pseudomonas aeruginosa bacteria, an opportunistic pathogen in cystic fibrosis and other diseases. DEV is part of an experimental phage cocktail developed to eradicate P. aeruginosa infection in pre-clinical studies. Bacterial viruses, known as phages, are the most abundant biological entities on the planet and are increasingly used as biomedicines to eradicate antibiotic-resistant pathogenic bacteria.

Having happy intimate partners might not only lift our moods, but it also helps us manage stress, especially as we age, according to new research. When comparing individuals' self-reported emotional states and relationship satisfaction with their levels of cortisol, researchers observed that older couples have lower levels of the stress hormone when their partners feel positive emotions. This effect was even stronger for people who reported higher satisfaction in their... Read more ›
