Testing for'Bad Cholesterol' Doesn't Tell the Whole Story So why don't more doctors use it? For decades, assessing cholesterol risk has been built around a simple idea: Lower "bad" cholesterol, lower your chance of a heart attack . The test at the center of that approach measures how much low-density lipoprotein, or LDL cholesterol, is circulating in part of the blood. It has shaped everything from clinical guidelines to the widespread use of statins, medications that reduce LDL. Lowering LDL cholesterol reduces heart attacks, strokes, and early death.

Researchers have developed three new antibiotics from scorpion venom and habanero peppers to combat tuberculosis and other drug-resistant pathogens. Researchers from the National Autonomous University of Mexico (UNAM) have identified new ways to combat tuberculosis and reduce bacterial resistance, developing three new antibiotics derived from scorpion venom and habanero peppers. A team led by Lourival Domingos Possani Postay, from the Institute of Biotechnology's Morelos campus, created two drugs that demonstrated efficacy against the bacterium, responsible for tuberculosis, as well as against, a microorganism that in hospital environments can cause various clinical complications, from skin infections to potentially fatal diseases such as pneumonia, meningitis, septicemia, and endocarditis. The antibiotics were derived from the venom of the scorpion, native to the state of Veracruz. The team was able to isolate two colorless molecules called benzoquinones--heterocyclic compounds that do not contain amino acids--from the arachnid's toxin.

New research suggests that reliance on AI assistants can have a negative impact on people's ability to think and problem solve. Using AI chatbots for even just for 10 minutes may have a shockingly negative impact on people's ability to think and problem-solve, according to a new study from researchers at Carnegie Mellon, MIT, Oxford, and UCLA. Researchers tasked people with solving various problems, including simple fractions and reading comprehension, through an online platform that paid them for their work. They conducted three experiments, each involving several hundred people. Some participants were given access to an AI assistant capable of solving the problem autonomously.
