- This emerging treatment is helping people avoid knee replacement surgeryon June 23, 2026 at 3:04 am
A minimally invasive treatment called GAE is helping people with chronic knee pain get back to gardening, cycling, and other activities without undergoing knee replacement surgery. Early studies suggest the procedure can provide years of relief by reducing inflammation inside the joint.
- Scientists say most people need more protein than current guidelines suggeston June 23, 2026 at 1:44 am
A new review suggests that doing more exercise and eating more protein than current minimum recommendations may help people stay stronger, sharper, and more independent as they age. The goal isn’t building a beach body—it’s extending healthspan and maintaining the ability to fully enjoy life for decades longer.
- A common vitamin could help fight one of the deadliest brain cancerson June 22, 2026 at 12:23 pm
A clinical trial is exploring whether high doses of vitamin B3 could give patients with glioblastoma a better chance against the aggressive brain cancer. Scientists found that niacin may help revive immune cells that tumors shut down, allowing them to attack cancer more effectively. Early results have been promising, with patients showing significantly better progression-free survival than expected.
- Butterfly that barely ages could help unlock longevity secretson June 22, 2026 at 10:30 am
Scientists discovered that Heliconius butterflies have evolved an extraordinary lifespan, living several times longer than closely related species. Even more surprising, some show little sign of physical decline as they age. Their unusual pollen-feeding lifestyle may play a role, but the research suggests deeper evolutionary changes are also helping them stay healthy for longer.
- Ebola and hantavirus can start like the flu but turn deadly faston June 22, 2026 at 6:30 am
Two dangerous viruses are back in the spotlight, reminding health officials how quickly infectious diseases can become serious threats. Hantavirus, often linked to rodents, can cause severe heart and lung complications and has no specific treatment or vaccine, while certain strains can even spread between people. Ebola remains one of the world’s most feared diseases, with some outbreaks killing up to half of those infected, although vaccines and antivirals have improved outcomes for some strains.
- One common fat may fuel type 2 diabetes while another helps fight iton June 22, 2026 at 12:25 am
Not all fats affect your body the same way. Researchers found that palmitic acid, a saturated fat common in many foods, may contribute to insulin resistance and type 2 diabetes by triggering inflammation, toxic fat buildup, and cellular stress. In contrast, oleic acid—the heart-healthy fat abundant in olive oil—appears to help protect insulin function and may even counter some of the harmful effects of palmitic acid.
- Long-lived families reveal a rare genetic clue to healthy agingon June 21, 2026 at 2:57 pm
A study of long-lived families has identified rare genetic variants that may help people stay healthier for much longer as they age. One standout mutation appears to temper inflammation, potentially delaying disease and extending years of healthy living.
- Tubulin prevents toxic brain protein clumps linked to Alzheimer’s and Parkinson’son June 21, 2026 at 1:08 pm
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.
- Yale study finds nearly half of older adults improved with ageon June 21, 2026 at 10:02 am
A long-term Yale study is challenging one of the biggest myths about aging. Nearly half of adults over 65 improved physically, mentally, or both over time, despite the common belief that aging means constant decline. Researchers found that people with more positive attitudes about getting older were significantly more likely to show these gains.
- Scientists discover neurons must break their DNA to build the brainon June 21, 2026 at 6:30 am
As newborn neurons make their way through the developing brain, they must squeeze through incredibly tight spaces to reach their final destinations. Researchers discovered that this physical journey routinely causes some of the most severe forms of DNA damage—double-strand breaks—yet the young brain has evolved an impressive ability to repair the damage almost immediately.
