Long before evolution equipped them with the right teeth, early humans began eating tough grasses and starchy underground plants—foods rich in energy but hard to chew. A new study reveals that this bold dietary shift happened 700,000 years before the ideal dental traits evolved to handle it.

Between 2003 and 2021, Earth saw a net boost in photosynthesis, mainly thanks to land plants thriving in warming, wetter conditions—especially in temperate and high-latitude regions. Meanwhile, ocean algae struggled in increasingly stratified and nutrient-poor tropical waters. Scientists tracked this global energy shift using satellite data, revealing that land ecosystems...

A jaw-dropping 515-mile lightning bolt lit up the skies from Texas to Kansas City, smashing previous records and reshaping our understanding of extreme weather. Thanks to advanced satellite tech, scientists like Randy Cerveny and Michael Peterson are uncovering the mechanics of "megaflash" lightning—rare, colossal discharges that span hundreds of miles...

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.

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...

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.

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...

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...

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.

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.
