Scientists discover that cranberry juice may help fight tooth decay
Cranberry juice may offer an unexpected benefit beyond its reputation for helping prevent urinary tract infections: protecting teeth from decay. Researchers at the University of Illinois Chicago discovered that pure, unsweetened cranberry juice slowed the regrowth of dental plaque bacteria and reduced their production of acids that damage tooth enamel. The secret may lie in naturally occurring compounds called proanthocyanidins, which interfere with harmful bacteria.
Your blood pressure could be dangerous even when your numbers look normal
Researchers have discovered a small group of brain cells that prevents dangerous blood pressure swings, even when average readings appear normal. The finding reveals a hidden source of cardiovascular risk and could open the door to new treatments that protect the heart and brain.
Scientists discover a hidden reason why muscles weaken with age
Scientists have uncovered a hidden defense mechanism in aging muscles that sacrifices strength to protect cells from damage. In mice, partially restoring a crucial molecule reversed signs of muscle wasting and prevented premature death, raising hopes for new treatments for age-related muscle decline.
Common drugs may help dangerous viruses spread through the body
A surprising discovery reveals that widely used anti-inflammatory drugs may unintentionally help dangerous viruses spread through the body. Scientists found that JAK inhibitors, prescribed for rheumatoid arthritis and other inflammatory diseases, can weaken a crucial immune defense against influenza, COVID-19, and other infections. By suppressing genes that normally fight viruses, these medications may leave patients more vulnerable to infection.
A simple liquid can stop cavities without drilling, major study confirms
A simple liquid painted onto teeth in seconds can stop cavities without drilling, injections, or anesthesia, according to a major clinical trial involving young children. The inexpensive treatment could spare thousands of children painful dental procedures and surgery while paving the way for broader FDA-approved use.
