Tubulin prevents toxic brain protein clumps linked to Alzheimer’s and Parkinson’s

Scientists at Baylor College of Medicine may have uncovered a promising new way to combat Alzheimer’s and Parkinson’s disease. Instead of trying to stop Tau and alpha-synuclein proteins from gathering into tiny droplets inside brain cells, the researchers found that tubulin—the protein that builds the cell’s internal transport network—can redirect these proteins away from forming toxic clumps and toward healthy, productive work.

Major review finds vaping likely causes lung and oral cancer

Researchers have concluded that nicotine vapes are likely to cause lung and oral cancers, based on evidence ranging from human biomarkers to animal and laboratory studies. The findings challenge the idea that vaping is a harmless alternative to smoking and suggest health risks may be emerging much sooner than many expected.

Scientists May Have Found What Really Triggers Alzheimer’s Disease

Scientists may have uncovered a hidden trigger behind Alzheimer’s disease. Instead of plaques being the root cause, amyloid beta appears to interfere with tau, a protein that helps keep neurons functioning properly. This disruption could set off the damage that eventually leads to the disease’s most recognizable brain changes.

Ancient DNA reveals plague was already killing humans 5,500 years ago

Plague was already a deadly killer 5,500 years ago, long before cities, farming, or the rat-infested conditions usually linked to historic outbreaks. By analyzing ancient DNA from hunter-gatherer cemeteries in Siberia, researchers discovered early plague strains in nearly 40% of the individuals studied and found evidence of rapid family-based outbreaks that wiped out many children and young teenagers.

A surprising discovery reveals the kidney has a secret backup system

Scientists at Mayo Clinic have uncovered a surprising new way the kidneys conserve water, revealing a hidden backup system that works independently of the hormone long believed to control the process. The discovery emerged when researchers testing an old drug called probenecid expected it to worsen polycystic kidney disease (PKD) but found it actually slowed cyst growth instead.

Common plastic chemical linked to lifelong anxiety in new study

Exposure to a common plastic chemical before and shortly after birth may have lasting effects on behavior. Researchers found that male rats exposed early in life to DEHP—a plasticizer used in products ranging from medical devices to toys—showed significantly higher anxiety as adults, even long after exposure had ended. The animals were more hesitant to explore open spaces and spent more time frozen in place, classic signs of anxiety in rodents.

Scientists say most of what’s in your food is still a mystery

Scientists are beginning to explore a hidden world of thousands of food chemicals that go far beyond the nutrients listed on nutrition labels. This “nutritional dark matter” may hold the key to understanding disease risk, healthy aging, and why different diets affect people in dramatically different ways.

Your brain was never designed for this much bad news

Humans evolved to pay close attention to danger, but today that instinct is being overwhelmed by an endless supply of bad news from around the world. Researchers say the answer isn’t to stop following current events—it’s to build healthier habits around how, when, and where we get our news.
