Millions of people live with chronic nerve pain that can make even the lightest touch feel intense and unbearable. Scientists have long believed that this kind of pain may begin when mitochondria, the tiny structures that produce energy inside cells, stop working properly in damaged nerves. Now, researchers at Duke…
Popular weight loss and diabetes medications such as semaglutide and tirzepatide have transformed treatment for obesity and blood sugar control. Now, researchers at the University of Pennsylvania say artificial intelligence may also help uncover side effects that patients are discussing online but that are not always fully reflected in clinical…
Three years ago, scientists detected something extraordinary deep beneath the Mediterranean Sea: the most energetic cosmic neutrino ever observed. The particle carried an astonishing energy of around 220 PeV, more than ten times greater than previously detected high energy neutrinos, and researchers still do not know exactly where it came…
An international team of researchers has directly observed how angular momentum moves through a crystal lattice for the first time, revealing an unexpected quantum effect that causes the direction of rotation to reverse. The discovery, made using intense terahertz laser pulses, gives scientists a new view into the fundamental origins…
Scientists may have uncovered a hidden biological switch that helps control how quickly the body ages. Research published in PLOS Biology suggests that declining levels of a brain protein called Menin can trigger inflammation, memory decline, and other age-related changes throughout the body. In experiments with mice, restoring the protein…
Taking vitamin D2 might lower the body’s levels of the more efficient form of vitamin D, vitamin D3, according to new research from the University of Surrey, John Innes Centre and Quadram Institute Bioscience. 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…
