Colistin, a last-resort antibiotic, is losing its power due to rising resistance—and the culprits might be hiding in your seafood dinner. A University of Georgia research team discovered colistin-resistance genes in bacteria found in imported shrimp and scallops from markets in Atlanta. These genes can hop between bacteria via plasmids, potentially turning once-curable infections into deadly threats.

A simple blood test could reveal which early Alzheimer’s patients are most at risk for rapid decline. Researchers found that people with high insulin resistance—measured by the TyG index—were four times more likely to experience faster cognitive deterioration. The study highlights a major opportunity: a common lab value already available in hospitals could help guide personalized treatment strategies. This discovery also uncovers a unique vulnerability in Alzheimer’s disease to metabolic stress, offering new possibilities for intervention while the disease is still in its early stages.

These are the first public images collected by the Chile-based observatory, which will begin a decade-long survey of the southern sky later this year.

The Proba-3 spacecraft succeed at creating solar eclipses, kicking off a two-year mission to study the sun’s mysterious outer atmosphere, the corona.

The whales use quick body movements to tear pieces of bull kelp for use as tools, perhaps the first known toolmaking by a marine mammal.

With genetic tweaks, E. coli turned 92 percent of broken-down plastic into acetaminophen, charting a path to upcycle plastic waste sustainably.

The huge market for stolen smartphones means that thieves will continue to snatch them, but is there anything we can do to put a stop to this crime wave?

Quantum computers have been hyped as machines that can solve almost any problem. Yet it is becoming clearer that their near-term utility will be narrower

There is mounting evidence that even surprisingly simple animals, like invertebrates, have a level of consciousness – but not in the way you might think
