Straight from the heart: Mysterious lipids may predict cardiac problems better than cholesterol
Stephanie Blendermann, 65, had good reason to worry about heart disease. Three of her sisters died in their 40s or early 50s from heart attacks, and her father needed surgery to bypass clogged arteries. She also suffered from an autoimmune disorder that results in chronic inflammation and boosts the odds of developing cardiovascular illnesses. “I have an interesting medical chart,” says Blendermann, a real estate agent in Prior Lake, Minnesota. Yet Blendermann’s routine lab results weren’t alarming. At checkups, her low-density lipoprotein (LDL), or “bad,” cholesterol hovered around the 100 milligrams-per-...

Scientists use AI to decipher words and sentences from brain scans
A technique based on artificial intelligence (AI) can translate brain scans into words and sentences, a team of computational neuroscientists reports. Although in the early stages and far from perfect, the new technology might eventually help individuals with brain injuries or paralysis regain the ability to communicate, researchers say. The study “shows that, using the right methods and better models, we can actually decode what the subject is thinking,” says Martin Schrimpf, a computational neuroscientist at the Massachusetts Institute of Technology who was not involved in the work. Other research teams hav...

These ants are ballooning with microbe-killing honey
Buried deep underneath the red, sunbaked soil of Australia’s deserts are hidden treasure troves of honey. It’s not the delicacy produced by bees, but rather the only type of honey made by ants. It’s also, a new study confirms, a potentially powerful medicine with antimicrobial properties. Australia’s Indigenous peoples have long used honey from honeypot ants ( Camponotus inflatus ) to treat a variety of maladies, from sore throats to infected wounds. Now, Western scientists are finally getting up to speed. In a study published today in PeerJ , researchers show that the honeypot ant’s honey has...
