 Microlithic projectile points from Uzbekistan may link Central Asia to a revised story of Homo sapiens’ early expansion into Europe. Researchers have identified tiny triangular projectile points at the Obi Rakhmat site in Uzbekistan by studying the marks left when they struck targets. Found in the site’s oldest occupation layers, the points date back 80,000 [...]

| Archaeologists Discover Evidence of “Brands” 3,200 Years Before Modern Capitalism |
|
|
2026-08-30 10:48:23 +00:00
 Researchers found that brands existed long before modern capitalism. Long before modern corporations and capitalism, craftspeople may already have been producing goods with a recognizable identity that traveled far beyond their place of origin. An international team led by Marta Luciani of the University of Vienna has found evidence that distinctive painted pottery made in [...]

| “Zombie” Cells Reveal a Surprising New Driver of Chronic Inflammation |
|
|
2026-08-30 01:51:47 +00:00
 Dysfunctional mitochondria may drive age-related inflammation by helping switch on inflammatory genes, and blocking SLC25A1 reduced that activity. As people age, senescent cells accumulate in the body. These so-called “zombie” cells have stopped dividing but remain metabolically active, releasing inflammatory molecules that can contribute to persistent inflammation associated with frailty, cardiovascular disease, cancer, neurodegeneration, and [...]

| The Rare Vision Side Effect of Ozempic and Wegovy You Should Know About |
|
|
2026-08-30 00:36:28 +00:00
 Rutgers researchers say the risk is low, but patients should still be aware of the possible association. GLP-1 medications have become widely used for Type 2 diabetes and obesity, with drugs such as semaglutide, sold as Ozempic and Wegovy, and tirzepatide, sold as Mounjaro and Zepbound, among the best-known examples. The drugs can also reduce [...]

 NASA’s Roman Space Telescope will combine a panoramic view of the cosmos with powerful tools for probing dark energy and hidden worlds. NASA’s Nancy Grace Roman Space Telescope is just one day from launch, and it is built to see the universe in a way no major space telescope has before. Roman will combine Hubble-like [...]

| Hidden Deep Beneath Mars, Scientists Find Evidence of a Vast Magmatic System |
|
|
2026-08-29 20:11:36 +00:00
 Mars may have built a surprisingly complex crust through large magmatic systems without the plate tectonics long thought necessary. Mars has no moving tectonic plates, yet deep beneath its surface may lie evidence of the kind of vast, interconnected magmatic systems once thought to require them. Researchers from the University of Oxford have found signs [...]

| One Tiny Chemical Difference in RNA Could Help Explain the Origins of Life |
|
|
2026-08-29 16:57:39 +00:00
 A tiny chemical difference makes RNA better than DNA at forming liquid-like droplets under high temperatures and acidic conditions. One of the biggest puzzles in origin of life research comes before the first cells even existed: How could RNA molecules gather in one place, interact, and help produce early life without cellular compartments to hold [...]

| Your Gut Microbiome May Be Contagious, Scientists Discover |
|
|
2026-08-29 15:42:36 +00:00
 In addition to diet and medication, person-to-person transmission can also play an important role in shaping the microbiome. The human gut contains a vast community of trillions of microorganisms (the microbiome) that helps shape digestion, immune function, and metabolism. A team led by the University of Vienna used a method called ‘reverse ecology’ to show [...]

| New Drug Combination Shows Promise Against Advanced Prostate Cancer |
|
|
2026-08-29 12:23:25 +00:00
 Researchers identified a promising approach to slowing treatment-resistant prostate cancer by targeting two key cancer pathways at the same time. Prostate cancer is diagnosed in about one in eight men during their lifetime. Many survive the disease, but for some, it eventually spreads beyond the prostate and becomes metastatic. In the United States, prostate cancer [...]

| Scientists Find a Troubling Effect of Sitting That Exercise Couldn’t Prevent |
|
|
2026-08-29 11:08:02 +00:00
 Improved fitness did not prevent prolonged sitting from impairing blood-vessel function in the legs. Long hours of sitting are often treated as something a good workout can offset. But new research from Dalhousie University suggests the cardiovascular effects of prolonged inactivity may be harder to undo. Published in the European Journal of Applied Physiology, the [...]

| FDA Clears First-of-Its-Kind Nonmedication Treatment for PTSD |
|
|
2026-08-29 00:14:14 +00:00
 The FDA has cleared a system that uses brain activity data to personalize magnetic stimulation for PTSD, adding a new nonmedication treatment option. Every day in the United States, approximately 17.5 veterans die by suicide, while 7% of veterans are diagnosed each year with post-traumatic stress disorder (PTSD). Against this backdrop, researchers at Texas A&M [...]
