A Penn State-led research team has unraveled the long-standing mystery of how lightning begins inside thunderclouds. Their findings offer the first quantitative, physics-based explanation for lightning initiation—and a glimpse into the stormy heart of Earth’s atmosphere.
Scientists just solved the 9-million-year mystery of where potatoes came from
About 9 million years ago, a wild interspecies fling between tomato-like plants and potato relatives in South America gave rise to one of the world’s most important crops: the potato. Scientists have now traced its roots to a rare natural hybridization that created the tuber, a storage organ that allowed...
4,000-year-old teeth reveal the earliest human high — Hidden in plaque
Scientists have discovered the oldest direct evidence of betel nut chewing in Southeast Asia by analyzing 4,000-year-old dental plaque from a burial in Thailand. This breakthrough method reveals invisible traces of ancient plant use, suggesting psychoactive rituals were part of daily life long before written records.
Did drunk apes help us evolve? New clues reveal why we digest alcohol so well
Ape behavior just got a name upgrade — “scrumping” — and it might help explain why humans can handle alcohol so well. Researchers discovered that African apes regularly eat overripe, fermented fruit off the forest floor, and this habit may have driven key evolutionary adaptations. By naming and classifying this...
Drones reveal 41,000-turtle nesting mega-site hidden in the Amazon
A team at the University of Florida used drones and smart modeling to accurately count over 41,000 endangered turtles nesting along the Amazon’s Guaporé River—revealing the world’s largest known turtle nesting site. Their innovative technique, combining aerial imagery with statistical correction for turtle movement, exposes major flaws in traditional counting...
How AI is supercharging plant immunity to fight deadly bacteria
Scientists have used artificial intelligence to upgrade plant immune systems, potentially revolutionizing how crops like tomatoes and potatoes can defend against harmful bacteria. By reengineering plant receptors that recognize bacterial threats, they are enhancing plant resistance and preparing for a future of more resilient crops.
Clockwork from scratch: How scientists made timekeeping cells
Scientists at UC Merced have engineered artificial cells that can keep perfect time—mimicking the 24-hour biological clocks found in living organisms. By reconstructing circadian machinery inside tiny vesicles, the researchers showed that even simplified synthetic systems can glow with a daily rhythm—if they have enough of the right proteins.
400-million-year-old fish exposes big mistake in how we understood evolution
A fish thought to be evolution’s time capsule just surprised scientists. A detailed dissection of the coelacanth — a 400-million-year-old species often called a “living fossil” — revealed that key muscles believed to be part of early vertebrate evolution were actually misidentified ligaments. This means foundational assumptions about how vertebrates,...
Digital twins are reinventing clean energy — but there’s a catch
Researchers are exploring AI-powered digital twins as a game-changing tool to accelerate the clean energy transition. These digital models simulate and optimize real-world energy systems like wind, solar, geothermal, hydro, and biomass. But while they hold immense promise for improving efficiency and sustainability, the technology is still riddled with challenges—from...
Did humans learn to walk in trees?
In the quest to understand how and why early humans started walking on two legs, scientists are now looking to chimpanzees living in dry, open savannah-like environments for clues. A new study reveals that these chimpanzees, despite the open terrain, still frequently climb trees to gather fruit and other foods...
