• Virginia scientists discover the cues black bears use for hibernation

  30-08-2026 16:31 via popsci.com
  
  Researchers have long assumed that the timing of American black bear (Ursus americanus) annual hibernation mostly depends on temperature. However, new research indicates that how the bears know it’s time to hibernate might be more complicated than they once thought. A team from Virginia Tech investigated how temperature and daylight hours interact to influence the species’ hibernation behavior. To do so, the team followed the activity of four wild, pregnant female bears througho

• Can apps really make you fluent in another language?

  30-08-2026 14:03 via popsci.com
  
  For the last five months, I’ve had a daily date with a little green owl. It cheers me on when I finish a language lesson and sends passive-aggressive reminders when I put it off. A few months in, I was thrilled to realize I could follow bits of a German conversation I happened to overhear. But I still wondered: If I keep using this app, will I actually be able to understand entire conversations and express myself clearly? So I asked some experts.What language apps do wellApps like Duo

• Archaeologists Discover Evidence of “Brands” 3,200 Years Before Modern Capitalism

  30-08-2026 12:48 via scitechdaily.com
  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

  30-08-2026 03:51 via scitechdaily.com
  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

  30-08-2026 02:36 via scitechdaily.com
  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 [...]

• Hidden Deep Beneath Mars, Scientists Find Evidence of a Vast Magmatic System

  29-08-2026 22:11 via scitechdaily.com
  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 [...]

• How gross is wearing your shoes inside?

  29-08-2026 19:00 via popsci.com
  
  Do you take your shoes off when you enter your home? If not, I think you’re disgusting (sorry, not sorry, I’m Canadian)! Jokes aside, there is a real cultural divide around whether you take your shoes off when entering a home. The practice varies internationally. It’s the norm in much of Asia, for example. In the United States, however, the practice varies. A 2018 YouGov poll found that only 31 percent of Americans “always” take off their shoes at home, but mos

• One Tiny Chemical Difference in RNA Could Help Explain the Origins of Life

  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 [...]

  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 [...]

  Mountain yellow-legged frogs used to be the kings of the mountain. Specifically, the Sierra Nevada mountains, where they were once the region’s most common amphibians only. But their reign has since plummeted dramatically. Now 92 percent of their historic range is void of the colorful animal.“These frogs used to be quite abundant.

  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 [...]

• Why you shouldn’t trust everything you find in an AI web search

  One of the many ways that AI chatbots like ChatGPT and Gemini can help you is in searching the web. Indeed, if you load up the Google website these days, AI search is pretty much forced on you—the traditional, ranked list of blue links is some way down the page, if it appears at all.This new type of information retrieval can feel more natural and convenient—like having a conversation with an expert rather than diving through pages and pages of results—but is it actually any mor

  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 [...]

• Why the AI Capability Multiplier Has Compressed to 3.1 Months From 3.5

  28-08-2026 23:06 via technocracy.news
  
  I have been tracking the progress of AI since January 2025, since Trump’s inauguration. Initially, starting at one, I pegged the doubling factor at 3.5 months; then I adjusted it lower to 3.3 on August 17th. After further research, I am settling it back to 3.1, which is 13.43 weeks. This is the time it takes for AI to double in raw ability, breadth, and the ability to create useful work.
  Today, that number stands at 52. Think about it. AI is 52 times more capable today than 20 months ago.
