A new way to spot type‑2 diabetes is coming from an unexpected source: your own spit. Scientists have found that tiny particles in saliva, called extracellular vesicles, carry the same clues about insulin problems that doctors look for in blood. These particles are packed with proteins, fats and tin
A recent study looked at a big group of people in Iran to see if how religious they are could explain why some people with antisocial traits also use drugs. Researchers started by collecting data from thousands of participants, noting their level of religious belief and how often they used illega
The Hormel Institute at the University of Minnesota runs a summer program that sends undergraduates into research labs. Students get hands‑on work and training for future careers in biomedical science. One intern, Noah Zimmerman, started a project that ended up in a peer‑reviewed journal. Zimmerman
The University of Florida’s wildlife team, called “Croc Docs, ” spends most nights in the Everglades hunting two dangerous species: alligators that need health checks and Burmese pythons that threaten native life. Instead of waiting for the sun, they launch airboats under moonlight and use radio
A team of scientists has found a clever trick for putting single nickel atoms inside special tiny cages called zeolites. Zeolites are like honeycomb structures that can trap molecules and help chemical reactions happen faster. The new method keeps the nickel atoms from clumping together, which is a
A team of researchers tried a fresh approach to clean up the nasty chemical cyanide that often ends up in mining wastewater. They mixed a special material called bismuth vanadate (BiVO₄) with ozone gas and exposed the mixture to light. The goal was to break down cyanide that is stuck inside metal‑cy
Lead pollution hurts barley plants in many ways. It slows growth, damages the photosynthetic machinery, and lowers key minerals like calcium and potassium. The plants also suffer from more cell damage, shown by higher levels of harmful molecules such as MDA and hydrogen peroxide. In a separate group
Jean‑Martin Charcot, a key figure in early neurology, is remembered this year as part of his 200th birthday. He worked in Paris and helped shape modern brain study, while also becoming a friend of writer Alphonse Daudet. Their friendship later soured because Daudet, who had a serious nerve disease,
A recent study from several hospitals across Japan looked at how two different kinds of PET scanners perform when used for breast imaging. The first type is a “ring‑shaped” machine that surrounds the patient, while the second uses an “opposite‑type” design that places detectors on opposite sides. Re
Fungi can change their shape on the fly. When the outside world shifts, they switch between cell forms to survive or infect. Scientists know a lot about the genes that trigger these changes, but they have not looked closely at what fuels them. A new study shows that the sugar‑processing rou
