| Unexpected Hormone Discovery Could Change How We Treat Arthritis |
|
|
2026-04-28 20:32:41 +00:00
Researchers have uncovered a previously unobserved presence of the GLP-1 hormone in the joints of arthritis patients. Arthritis is not a single disease but a broad category of joint disorders that includes autoimmune conditions like rheumatoid arthritis and psoriatic arthritis, as well as degenerative diseases such as osteoarthritis. Despite their differences, many forms share common [...]

| Scientists Supercharge “Natural Killer” Cells To Break Through Cancer’s Defenses |
|
|
2026-04-28 19:57:51 +00:00
 A new strategy to strengthen the body’s natural immune defenses against cancer is showing early promise, particularly for patients with limited treatment options. Scientists have developed a new way to strengthen the cancer-fighting ability of natural killer (NK) cells, which serve as an early defense in the immune system. These cells can identify and destroy [...]

| Simple “Gut Reset” May Prevent Weight Gain After Ozempic or Wegovy |
|
|
2026-04-28 19:22:32 +00:00
 A quick “gut reset” may help keep weight off after Ozempic. A new outpatient procedure could help people avoid regaining weight after stopping popular medications like Ozempic and semaglutide, according to research to be presented at Digestive Disease Week (DDW) 2026. Experts estimate that about 70% of people who discontinue these drugs regain much of [...]

| Ancient DNA Study Reveals Human Evolution Is Happening Faster Than We Thought |
|
|
2026-04-28 14:27:57 +00:00
 New research challenges long-standing assumptions about human evolution, revealing that natural selection has been more active—and more recent—than once believed. A sweeping analysis of ancient DNA from nearly 16,000 people is reshaping how scientists understand human evolution. By tracking genetic changes across more than 10,000 years in West Eurasia, researchers found that natural selection has [...]

2026-04-28 11:48:56 +00:00
 Memory has limits but can be improved with focus, chunking, and spaced repetition. Testing recall and reducing distractions are key to remembering more effectively. Research suggests that improving memory may be less about ability and more about subtle shifts in daily habits. A handful of science-backed techniques, ranging from reducing distractions to rethinking how we [...]

2026-04-28 03:51:02 +00:00
 New research suggests that many planets previously considered promising for life may, in fact, be far less hospitable. A distant planet might sit in the perfect orbit for life, with temperatures just right for liquid water. But if that world is too dry, it could still be completely uninhabitable. New research suggests that many so-called [...]
