Many people take vitamin D supplements to support their bone and immune health and meet the…
Mangoes are among the world’s most popular tropical fruits, valued for their sweet flavor and rich nutritional content. But once harvested, mangoes continue to ripen quickly, making them highly vulnerable to softening, moisture loss, and spoilage during storage and transport. Now, researchers from Hainan University have uncovered why storing mangoes…
Demand for lithium is soaring as automakers ramp up electric vehicle production and energy companies build larger battery systems to support wind and solar power. But producing lithium remains a slow and environmentally costly process. Current extraction methods work best with high quality deposits found in only a limited number…
A new study suggests that Wegovy, the popular weight loss drug, may carry a higher risk of a rare eye condition that can lead to sudden vision loss compared with other semaglutide medications. The condition, called ischemic optic neuropathy (ION), occurs when blood flow to the optic nerve is reduced…
Researchers at Helmholtz Munich, Ludwig Maximilians University Munich (LMU), and several partner institutions have created an artificial intelligence (AI) system capable of mapping disease-related changes throughout an entire mouse body at cellular-level detail. Using the new platform, known as MouseMapper, the team discovered widespread inflammation and previously unknown nerve damage…
NASA’s Psyche spacecraft made a close pass by Mars on May 15, flying within 2,864 miles (4,609 kilometers) of the planet’s surface as it continued its long journey through deep space. During the encounter, the spacecraft captured a series of images, including a striking view of the double-ring Huygens crater…
When NASA scientists first picked up a radio burst coming from the Sun in August 2025, the signal initially appeared routine. Solar radio bursts are fairly common and usually fade within hours or, in some cases, a few days. This event turned out to be anything but ordinary. Instead of…
Scientists have identified a massive new species of mosasaur, a marine reptile that lived alongside the dinosaurs and dominated prehistoric oceans. The newly described predator, named Tylosaurus rex (or T. rex), measured up to 43 feet long and ranks among the largest mosasaurs ever discovered. The research was led by…
Researchers in Germany are warning that ordinary WiFi networks could become a powerful new form of invisible surveillance. Using standard wireless signals and artificial intelligence, they demonstrated a system capable of identifying people with striking accuracy, even if those individuals are not carrying an active device. “By observing the propagation…
More people are paying close attention to what they eat, often tracking calories, exercising daily, and filling their plates with foods that seem naturally healthy, including fruits and vegetables. Yet even nutritious foods can carry hidden chemical concerns. Some contaminants can enter food from the environment, while others can form…
More than 135 million adults in the United States either have type 2 diabetes (T2D) or face an elevated risk of developing the condition, increasing the demand for reliable nutrition guidance backed by scientific research. A newly published randomized controlled trial (RCT) found that eating 6 to 7 ounces of…
Since their discovery in the 1950s, metallocenes have played a major role in organometallic chemistry. These compounds feature a metal atom positioned between two carbon rings, giving them a distinctive “sandwich” structure. Over the decades, scientists have explored their use in catalysts, advanced materials, energy technologies, sensors, and drug delivery…
Wormholes are often imagined as tunnels through space or time — shortcuts across the universe. But this image rests on a misunderstanding of work by physicists Albert Einstein and Nathan Rosen. In 1935, while studying the behavior of particles in regions of extreme gravity, Einstein and Rosen introduced what they…
Vitamin B12 is best known for helping the body make DNA, red blood cells, and healthy nerve tissue. But research suggests that simply meeting the current minimum standard may not always be enough, especially for older adults. A UCSF led study found that healthy older people with lower vitamin B12…
Nearly one in four adults over 40 lives with painful osteoarthritis, a condition that can make everyday movement difficult and is one of the major causes of adult disability. The disease gradually wears down the cartilage that cushions joints. Once that damage occurs, doctors currently cannot reverse it. Treatment usually…
Scientists have adapted a chemistry technique used in traditional glassmaking to improve a futuristic material known as metal-organic framework (MOF) glass. These materials are made from metal atoms connected by organic molecules and are valued for their ability to trap gases such as carbon dioxide and hydrogen, and even capture…
A team of researchers in South Korea has uncovered evidence that could shed new light on how Earth’s atmosphere first became rich in oxygen, one of the most important turning points in the planet’s history. Scientists from the Korea Institute of Geoscience and Mineral Resources (KIGAM) discovered stromatolites, layered rock…
Sea level rise is one of the clearest and most persistent consequences of human caused climate change. As global temperatures increase, oceans expand from the heat while melting glaciers and ice sheets add even more water to the seas. Scientists say the process is extremely difficult to stop and will…
Arthritis covers a wide range of joint disorders, including inflammatory conditions such as rheumatoid arthritis and psoriatic arthritis, as well as osteoarthritis, the most common form of the disease. Many people living with arthritis struggle with pain, stiffness, and reduced mobility that can significantly affect daily life. Current treatments mainly…
Aging research is entering a new phase as scientists rethink one of the body’s most mysterious cell types: senescent cells, often nicknamed “zombie cells.” While these aging cells have long been viewed as harmful drivers of inflammation and disease, new findings suggest the story is far more complicated. In some…
On certain nights in Japan, people may notice a faint red glow spreading low across the horizon. The dim crimson haze can be easy to overlook, but it is created by powerful activity taking place far above Earth. Streams of charged particles from the Sun travel toward our planet and…
Astronomers using NASA’s James Webb Space Telescope (JWST) have taken a close look at the atmosphere of a rare giant planet with temperatures surprisingly similar to those on Earth. The Saturn sized world, known as TOI-199b, contains methane in its atmosphere, according to a new study. The discovery stands out…
Researchers are offering a new way to understand why aging is so closely connected to chronic illness. In a review published in Aging-US titled “Aging as a multifactorial disorder with two stages,” scientists from University College London and Queen Mary University of London describe a model suggesting that diseases linked…
Language learning is often a daunting prospect. Many of us wish we had learned a language to a higher level at school. But even though adults of all ages can do well in acquiring a new language, fear – or the memory of struggling to memorize grammar at school –…
Children who regularly eat high-fat, high-sugar foods may experience lasting changes in the brain that continue long after their diets improve, according to a new study from University College Cork (UCC). Researchers also found that beneficial gut bacteria and prebiotic fibers could help reduce some of these long-term effects and…
New research suggests that GLP-1 weight loss medications may provide major long-term benefits for heart health in addition to helping people lose weight and manage blood sugar.

A recent study has identified a concerning connection between prenatal exposure to chlorpyrifos (CPF), a common insecticide, and lasting changes in brain structure as well as reduced motor function in children and adolescents. These findings, published in the journal JAMA Neurology, offer the first evidence of widespread, enduring impacts on…
Diseases such as cancer and neurodegenerative disorders often begin with genetic mistakes. But even after scientists identify the genes involved, turning that knowledge into effective treatments has remained extremely difficult. Many of these diseases are linked to hundreds of mutations spread across different biological pathways, making it hard to understand…
For decades, shrinking photonic devices has been far more difficult than miniaturizing electronic components. The challenge comes down to physics. Light cannot easily be confined into extremely small spaces because the uncertainty principle links its confinement to its wavelength. In visible and near infrared light, that wavelength can be up…
An international team of researchers, including a scientist from Aston University, has developed a new mathematical framework that explains the strange behavior of so called “breather” laser pulses. The breakthrough unites two very different types of laser dynamics under a single model for the first time. Ultrafast lasers generate incredibly…
