Aug. 15, 2025 Weaver ants have cracked a teamwork puzzle that humans have struggled with for over a century — instead of slacking off as their group grows, they work harder. These tiny architects not only build elaborate leaf nests but also double their pulling power when more ants join in. Using a “force ratchet” system where some pull while others anchor, they outperform the efficiency of human teams ...

Aug. 12, 2025 Scientists have discovered a parasite that can sneak into your skin without you feeling a thing. The worm, Schistosoma mansoni, has evolved a way to switch off the body’s pain and itch signals, letting it invade undetected. By blocking certain nerve pathways, it avoids triggering the immune system’s alarms. This stealth tactic not only helps the worm survive, but could inspire new kinds of ...

Aug. 7, 2025 Deep beneath the ocean's surface, a groundbreaking DNA study reveals that the deep sea is far more globally connected than once thought. By analyzing thousands of brittle stars preserved in museum collections, scientists discovered these ancient creatures have silently migrated across the planet's seafloor for millions of years, forming a vast evolutionary network from Iceland to ...

Aug. 22, 2025 As the ozone layer recovers, it’s also intensifying global warming. Researchers predict that by 2050, ozone will rank just behind carbon dioxide as a driver of heating, offsetting many of the benefits from banning ...

Aug. 19, 2025 Scientists found that Great Salt Lake’s chemistry and water balance were stable for thousands of years, until human settlement. Irrigation and farming in the 1800s and a railroad causeway in 1959 created dramatic, lasting changes. The lake now behaves in ways unseen for at least 2,000 ...

Aug. 9, 2025 Deep beneath the Antarctic seas lies a hidden network of 332 colossal submarine canyons, some plunging over 4,000 meters, revealed in unprecedented detail by new high-resolution mapping. These underwater valleys, shaped by glacial forces and powerful sediment flows, play a vital role in transporting nutrients, driving ocean currents, and influencing global climate. Striking differences between ...

July 11, 2025 Scientists have uncovered DNA from 214 ancient pathogens in prehistoric humans, including the oldest known evidence of plague. The findings show zoonotic diseases began spreading around 6,500 years ago, likely triggered by farming and animal domestication. These ancient infections may still influence us today, and help guide the vaccines of ...

July 3, 2025 When Siberian volcanoes kicked off the Great Dying, the real climate villain turned out to be the rainforests themselves: once they collapsed, Earth’s biggest carbon sponge vanished, CO₂ rocketed, and a five-million-year heatwave followed. Fossils from China and clever climate models now link that botanical wipe-out to runaway warming, hinting ...

June 3, 2025 Collapse of the West Antarctic Ice Sheet could be triggered with very little ocean warming above present-day, leading to a devastating four meters of global sea level rise to play out over hundreds of years according to a new study. However, the authors emphasize that immediate actions to reduce emissions could still avoid a catastrophic ...

June 3, 2025 A new study has finally confirmed the theory that the cause of extraordinary global tremors in September -- October 2023 was indeed two mega tsunamis in Greenland that became trapped standing waves. Using a brand-new type of satellite altimetry, the researchers provide the first observations to confirm the existence of these waves whose behavior is entirely ...
