| Scientists Uncover Fatal Weakness in “Zombie Cells” Linked to Cancer |
|
|
2026-05-03 00:04:10 +00:00
 A newly identified weakness in “zombie” cells may open the door to more precise cancer treatments by turning their own survival strategy against them. A new class of drugs takes advantage of a recently discovered weakness in “zombie-like” or senescent cells, opening the door to potential treatments for cancer and age-related diseases. Researchers from the [...]

| Scientists Debunk 100-Year-Old Belief About Brain Cells, Rewriting Textbooks |
|
|
2026-05-02 21:53:46 +00:00
 New evidence suggests axons may not be uniform tubes but dynamic, pearl-like structures. Johns Hopkins Medicine researchers say one of biology’s most familiar textbook images may be wrong, challenging a view of neuron structure that has persisted for more than a century. Axons, the long extensions neurons use to send signals, may not be smooth, [...]

| This Simple Home Device May Boost Brain Power in Adults Over 40 |
|
|
2026-05-02 21:18:26 +00:00
 HEPA air purifiers can slightly boost brain function in adults 40+, potentially reducing pollution-related cognitive decline. Using a HEPA air purifier for one month may modestly improve cognitive performance in adults over 40, particularly in areas like mental flexibility and executive function. The study, conducted in a high-traffic urban area, suggests that reducing exposure to [...]

| Ancient Roman Ship Coating Reveals Secrets Hidden for 2,200 Years |
|
|
2026-05-02 16:47:51 +00:00
 A new study of a 2,200-year-old Roman shipwreck reveals that ancient sailors used sophisticated organic coatings to waterproof their vessels. Since the earliest seafaring journeys, people have needed ships that could resist saltwater, stay watertight, and endure damage from marine organisms such as worms. Despite this long history, research into non-wood materials used in ship [...]

| Enormous Prehistoric Insects Puzzle Scientists |
|
|
2026-05-02 16:12:59 +00:00
 The true reason ancient insects grew so huge just got a lot more mysterious. Three hundred million years ago, Earth looked nothing like it does today. The continents were joined into a single landmass called Pangaea. Around the equator, vast coal-swamp forests dominated the landscape. Oxygen levels in the atmosphere were much higher than they [...]

| The Most Effective Knee Arthritis Treatments Aren’t What You Expect |
|
|
2026-05-02 12:58:19 +00:00
 A sweeping analysis of nearly 10,000 patients challenges assumptions about how best to treat knee osteoarthritis. For many people with knee osteoarthritis, relief may not require medication. A large new analysis suggests that simple physical treatments can ease pain and improve movement, often more effectively than some high-tech options. Knee osteoarthritis is one of the [...]

| Popular Weight-Loss Drugs Found To Cut Heart Attack and Stroke Risk |
|
|
2026-05-02 11:47:23 +00:00
 A large-scale analysis suggests that GLP-1 receptor agonists may do more than manage weight or blood sugar. New research suggests that GLP-1 weight loss drugs may provide lasting protection against heart attacks, strokes, and early death. Scientists at Anglia Ruskin University analyzed data from more than 90,000 patients across large international studies. They found that [...]
