The latest findings forecast that global life expectancy will increase by 4.9 years in males and 4.2 years in females between 2022 and 2050. Increases are expected to be largest in countries where life expectancy is lower, contributing to a convergence of increased life expectancy across geographies. The trend is largely driven by public health measures that have prevented and improved survival rates from cardiovascular diseases, COVID-19, and a range... Read more ›

A lack of detailed record-keeping in clinics and emergency departments may be getting in the way of reducing the inappropriate use of antibiotics, a pair of new studies suggests. In one of the studies, about 10% of children and 35% of adults who got an antibiotic prescription during an office visit had no specific reason for the antibiotic in their record. Read more ›

The basis of the marine food web in the Arctic, the phytoplankton, responds to heatwaves much differently than to constantly elevated temperatures. This has been found by the first targeted experiments on the topic. The phytoplankton's behavior primarily depends on the cooling phases after or between heatwaves. Read more ›

Scientists have discovered that a protein responsible for the synthesis of a key plant material evolved much earlier than suspected. This new research explored the origin and evolution of the biochemical machinery that builds lignin, a structural component of plant cell walls with significant impacts on the clean energy industry.

The sweet-taste receptor might be the first stop in a metabolic surveillance system for sugar. The receptor is also expressed in certain intestinal cells, where it may facilitate glucose absorption and assimilation, as part of this system. A team found that stimulation and inhibition of the sweet receptor helps regulate glucose metabolism in humans and may have implications for managing such metabolic disorders as diabetes. Read more ›

The new technique will map the top of the aquifer, called the 'water table,' spanning areas as large as hundreds of kilometers using a radar mounted on a high-altitude aircraft. According to the researchers, Desert-SEA will measure the variabilities in the depth of the water table on a large scale, allowing water scientists to assess the sustainability of these aquifers without the limitations associated with in-situ mapping in harsh and...

Thermoelectric materials could play an important role in the clean energy transition, as they can produce electricity from sources of heat that would otherwise go to waste. Researchers report a new approach to efficiently predict when thermoelectric materials will have improved performance in converting heat into electricity. Read more ›

Large language model-based chatbots can't effectively recognize users' motivation when they are hesitant about making healthy behavior changes, but they can support those who are committed to take action, say researchers. Read more ›

To date, approaches to treatments for Alzheimer's disease have not addressed the contribution of protein insolubility as a general phenomenon, instead focusing on one or two insoluble proteins. Researchers have recently completed a systematic study in worms that paints an intricate picture of the connections between insoluble proteins in neurodegenerative diseases and aging. Furthermore, the work demonstrated an intervention that could reverse the toxic effects of the aggregates by boosting... Read more ›

Important brain structures that are key for signaling in the brain are narrower and less dense in females, and more likely to be damaged by brain injuries, such as concussion. Long-term cognitive deficits occur when the signals between brain structures weaken due to the injury. The structural differences in male and female brains might explain why females are more prone to concussions and experience longer recovery from the injury than... Read more ›

A new sensor is giving researchers the best look yet at ATP levels inside living cells, enabling scientists to study in greater detail than ever before how fluctuations in this cellular currency affect the cell and contribute to disease. Read more ›

In an important step toward more effective gene therapies for brain diseases, researchers have engineered a gene-delivery vehicle that uses a human protein to efficiently cross the blood-brain barrier and deliver a disease-relevant gene to the brain in mice expressing the human protein. Because the vehicle binds to a well-studied protein in the blood-brain barrier, the scientists say it has a good chance at working in patients. Read more ›

Sea otters are one of the few animals that use tools to access their food, and a new study has found that individual sea otters that use tools -- most of whom are female -- are able to eat larger prey and reduce tooth damage when their preferred prey becomes depleted. Read more ›

Perceiving something -- anything -- in your surroundings is to become aware of what your senses are detecting. Today, neuroscientists identify, for the first time, brain-cell circuitry in fruit flies that converts raw sensory signals into color perceptions that can guide behavior. Read more ›

Celiac disease is a chronic autoimmune condition that occurs in around one per cent of the world's population. It is triggered by the consumption of gluten proteins from wheat, barley, rye and some oats. A gluten-free diet protects celiac patients from severe intestinal damage. Read more ›

Many people are concerned about residues of chemicals, contaminants or microplastics in their food. However, it is less well known that many foods also contain toxins of completely natural origin. These are often chemical compounds that plants use to ward off predators such as insects or microorganisms. These substances are found in beans and potatoes, for example, and can pose potential health risks. Read more ›

Perfluoroalkyl and polyfluoroalkyl substances, also known as PFAS or 'forever chemicals,' have become persistent pollutants in the air, water and soil. Because they are so stable, they can be transported throughout the water cycle, making their way into drinking water sources and precipitation. Precipitation introduces similar amounts of PFAS into each of the Great Lakes; however, the lakes eliminate the chemicals at different rates. Read more ›
