Often called "the window to the soul," the eyes may also offer clues about something less poetic but just as important: the health of the brain. A new study of tens of thousands of patients has revealed that cheap, simple and common photographs of the retina at the back of the eye can accurately predict many of the most common risk factors associated with developing Alzheimer's disease.
Inflammatory bowel disease (IBD) and other intestinal disorders affect millions of people worldwide, often causing lasting damage to the lining of the gut. In severe cases, this damage can become irreversible, leaving surgery as one of the few remaining treatment options. In recent years, however, regenerative medicine has emerged as a promising alternative approach, raising the possibility that damaged tissues could one day be repaired using a patient's own cells. Central to this vision are tiny three-dimensional replicas of human organs known as "organoids," which are grown from stem cells and can mimic important features of real tissues.

A paper on new research into the cause of death of Simonetta Vespucci, model for the world-renowned Birth of Venus by Sandro Botticelli, has been published by researchers at Queen Mary University of London, Universita Campus Bio-Medico di Roma and the University of California in the journal Endocrinology, Diabetes & Metabolism.
University of Queensland researchers have examined taste and smell genes to help determine whether specific foods cause or are linked to disease. People who like the taste and smell of onions are more likely to have lower blood pressure and risk of type 2 diabetes, they have found. The findings are published in the journal BMC Medicine.
Female chickadees living in monogamous mating systems will proactively seek out males that have better cognitive skills than their nest mate, according to new findings.
Paywalls are essential to the financial sustainability of news organizations, yet little is known about how readers respond when they encounter one. Do they subscribe, continue reading free content, look for ways around the paywall or leave the site altogether?
New research has found signs that may help researchers better understand why some babies are born early. Some signs are present as early as the first trimester.
One well-done gas giant, coming right up! That’s the latest from researchers analyzing NASA’s James Webb Space Telescope’s observations of HD 80606 b, an exoplanet four times the mass of Jupiter with an extremely elliptical orbit that sweeps close by its Sun-like star. The research team is presenting their study and preliminary findings Tuesday at […] The post NASA’s Webb Catches Exoplanet Getting Roasted appeared first on NASA Science.
Life on Earth has evolved under an uninterrupted rhythm of day and night. While light provides the energy that powers countless molecular processes, periods of darkness often allow biological systems to reorganize, recover and transform that energy into functional outcomes. Inspired by this natural balance, an international team led by Javier Montenegro at the Center for Research in Biological Chemistry and Molecular Materials (CiQUS) of the Universidade de Santiago de Compostela has demonstrated that the same principle can govern the behavior of simple synthetic molecular systems.
Orforglipron is beneficial for blood glucose control in individuals with type 2 diabetes using metformin or taking insulin glargine, according to two studies published online June 8 in The Lancet and the JAMA to coincide with the annual meeting of the American Diabetes Association, held from June 5 to 8 in New Orleans.
A study led by Georgia Institute of Technology's Associate Professor Costas Arvanitis takes a major step toward safer and more effective treatment and diagnosis of brain diseases. His team's research, published in Advanced Science, shows how combining artificial intelligence (AI) with focused ultrasound can safely deliver therapies and improve diagnostic interventions to the brain.
Many quantum effects can be observed only when a small number of particles is studied—individual atoms, molecules or photons, for example, carefully shielded from the rest of the world. But what about macroscopic objects, consisting of an unimaginably large number of particles? Can they, too, display effects that provide a direct glimpse into the quantum world?
A new study published in the journal Nature Conservation reveals that threatened amphibian species are being inadvertently or illegally sold under incorrect names in digital marketplaces. Using DNA barcoding, researchers discovered that frogs traded online as a widely farmed species, the Chinese edible frogs (Hoplobatrachus chinensis), were actually Chinese spiny frogs (Quasipaa spinosa), a species classified as Vulnerable by the IUCN.
A Yale-led team of astronomers has found a third galaxy devoid of dark matter—located alongside the other two in a formation that has never been seen before. Astronomers have followed a faint, cosmic trail of gas to a third galaxy that has no dark matter.
U.S. National Science Foundation-supported professor Kevin Minbiole discusses his work using artificial intelligence systems to discover new compounds to fight drug resistant bacteria...
Description NASA astronaut Jessica Meir inspects optical fibers while installing hardware updates to the agency’s Cold Atom Lab, or CAL, aboard the International Space Station on May 8, 2026. About the size of a minifridge and operated from Earth, CAL chills atoms to temperatures below minus 459 degrees Fahrenheit (minus 273.15 degrees Celsius), so close […] The post Astronaut Jessica Meir Assists With Hardware Updates for NASA’s Cold Atom Lab appeared first on NASA Science.
Hot and dry conditions have become synonymous with the risk of extreme wildfires. But a new paper argues that such conditions are not, by themselves, sufficient for blazes, and most warm years do not result in the burning of exceptionally large areas.
It is a common misperception that electrocardiograms (ECGs) simply contain data about heart activity. However, modern ECGs enhanced with artificial intelligence (AI) can contain data about a patient's sex, age, race and even exact identity derived from ECG signals, raising fresh privacy concerns. To address these worries, researchers from the University of Kansas have developed a privacy-preserving AI model called (PP-VAE) to protect personally sensitive data.
When living cells grow, divide or respond to drugs, they give off tiny amounts of heat that offer information about what the cells are doing. But because these heat signals are so vanishingly small, they have traditionally been impossible to measure directly. Researchers in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a calorimeter—a device that measures the heat transfer between a living system and its environment—that can detect metabolic heat signals on the order of 100 picowatts, or trillionths of a watt, in living cells.
