A three-year study of nearly 4,000 adults ranging from age 19 to 94 found that brain health can improve at any age, challenging the common belief that mental sharpness must decline as we get older. Participants spent just a few minutes a day on brain-training activities, and researchers found measurable gains across multiple aspects of brain health, including thinking clarity, emotional well-being, and sense of purpose.

Researchers have discovered how a parasite that causes malaria when transmitted through a mosquito bite can hide from the body's immune system, sometimes for years. It turns out that the parasite, Plasmodium falciparum, can shut down a key set of genes, rendering itself 'immunologically invisible.' Read more ›

Taste, pain, or response to stress -- nearly all essential functions in the human body are regulated by molecular switches called G protein-coupled receptors (GPCRs). Researchers have uncovered the fundamental mechanism how such a GPCR works. Using a method similar to the earth satellite GPS, they could track the motions of a GPCR and observe it in action. Their findings provide guidance for designing drugs. Read more ›

Scientists have decoded the atomic structure of Photosystem I from a 3-billion-year-old cyanobacteria lineage, offering a unique look at early oxygen-producing photosynthesis. The ancient nanodevice, purified from Anthocerotibacter panamensis, shows a remarkably conserved three-leaf-clover architecture for light absorption despite billions of years of evolution. The findings suggest that the fundamental design for harnessing sunlight was established very early in the history of life on Earth, predating the. Read more ›

New research from an international group looking at ancient sediment cores in the North Atlantic has for the first time shown a strong correlation between sediment changes and a marked period of global cooling that occurred in the Northern Hemisphere some 3.6 million years ago. The changes in sediments imply profound changes in the circulation of deep water currents occurred at this time. This crucial piece of work, which showed... Read more ›

Engineers have developed a groundbreaking computational model to study the movement of granular materials such as soils, sands and powders. By integrating the dynamic interactions among particles, air and water phases, this state-of-the-art system can accurately predict landslides, improve irrigation and oil extraction systems, and enhance food and drug production processes.

Investigators are developing a new type of auditory brainstem implant that is designed to be soft, and flexible and address limitations of models currently in use. These implants may one day benefit people who can't receive a cochlear implant, such as those with Neurofibromatosis type 2 (NF2) and other severe inner ear abnormalities. In a new preclinical study, researchers report on benefits in large animal models, and based on the... Read more ›

Researchers have found that wild orangutans vocalize with a layered complexity previously thought to be unique to human communication, suggesting a much older evolutionary origin. Read more ›

While Alzheimer's disease is mostly considered a disorder of the brain, emerging evidence suggests that the condition also affects other organs of the body. Working with the laboratory fruit fly, researchers provide a new understanding of how Alzheimer's disease affects different tissues across the entire body. The findings reveal new insights into brain-body communication in neurodegeneration and pave the way for identifying novel biomarkers and therapeutic targets for Alzheimer's disease. Read more ›

Intakes of dietary fiber and high-quality carbohydrates in midlife are linked to increased likelihood of healthy aging and other positive health outcomes in older women. Higher intakes of refined carbohydrates and starchy vegetables were associated with lower odds of healthy aging. Read more ›

Molecules like DNA are capable of storing large amounts of data without requiring an energy source, but accessing this molecular data is expensive and time consuming. Researchers have now developed an alternative method to encode information in synthetic molecules, which they used to encode and then decode an 11-character password to unlock a computer. Read more ›

In the natural world -- where predators pounce, prey flee, and group members feed and sleep in solidarity -- animal behavior is glorious in its variety. Now, new research suggests there may be an underlying architecture that orders the movements of animals as they go about their very different lives. And it's more widespread than previously imagined.

Humans perceive and navigate the world around us with the help of our five senses: sight, hearing, touch, taste and smell. And while scientists have long known that these different senses activate different parts of the brain, a new study indicates that multiple senses all stimulate a critical region deep in the brain that controls consciousness. The study sheds new light on how sensory perception works in the brain and... Read more ›

Until now, most research has used either generalized cell samples or organoids made from just one type of tropical fruit bat, and only from a single organ. But a breakthrough has arrived: a research team has now created the world's most comprehensive bat organoid platform. These 'mini-organs' are grown from five common bat species found across Asia and Europe and represent four different organs -- airway, lungs, kidneys, and small... Read more ›

That fit people have a reduced risk of premature death from various diseases is a recurring result in many studies. New research shows that people with high fitness levels in their late teens also have a reduced risk of dying from random accidents. This suggests that the associations seen in previous studies have probably been misleading. Read more ›

Using new observations with the ALMA telescope array in Chile, researchers have compiled the most precise map of three regions in the Milky Way's Central Molecular Zone to date, providing valuable information on how stars form in that region. Read more ›
