Scientists discovered true teeth growing on the head of the spotted ratfish, a distant shark relative. The toothed structure, called a tenaculum, helps males hold onto females during mating. Genetic evidence shows these head teeth share the same origins as oral teeth, overturning assumptions that teeth only evolve in jaws....
A giant asteroid hit Earth, but its crater is missing
Researchers discovered a new field of ancient tektites in South Australia, revealing a long-forgotten asteroid impact. These 11-million-year-old glass fragments differ chemically and geographically from other known tektites. Although the crater remains missing, the find exposes a massive event once thought unrecorded, offering clues to Earth’s tumultuous past and planetary...
Forged in fire: The 900°C heat that built Earth’s stable continents
New research reveals that Earth’s continents owe their stability to searing heat deep in the planet’s crust. At more than 900°C, radioactive elements shifted upward, cooling and strengthening the landmasses that support life. This ancient heat engine also distributed valuable minerals, giving scientists new clues for exploration and for spotting...
This tiny worm uses static electricity to hunt flying insects
A parasitic worm uses static electricity to launch itself onto flying insects, a mechanism uncovered by physicists and biologists at Emory and Berkeley. By generating opposite charges, the worm and insect attract, allowing the leap to succeed far more often. High-speed cameras and mathematical modeling confirmed this “electrostatic ecology” in...
A 151-million-year-old fly just changed what we know about evolution
Scientists have uncovered a 151-million-year-old midge fossil in Australia that challenges long-held views about insect evolution. Named Telmatomyia talbragarica, the fossil shows freshwater adaptations previously thought to exist only in marine species. This discovery suggests that Chironomidae may have originated in Gondwana, offering new insight into ancient biogeographical patterns.
Earth’s climate just crossed a line we can’t ignore
Humanity has reached the first Earth system tipping point, the widespread death of warm-water coral reefs, marking the beginning of irreversible planetary shifts. As global temperatures move beyond 1.5°C, the world risks cascading crises such as ice sheet melt, Amazon rainforest dieback, and ocean current collapse. Scientists from the University...
Ancient humans in Italy butchered elephants and made tools from their bones
Researchers in Italy discovered 400,000-year-old evidence that ancient humans butchered elephants for food and tools. At the Casal Lumbroso site near Rome, they found hundreds of bones and stone implements, many showing impact marks from butchery. The findings reveal a consistent prehistoric strategy for resource use during warmer Middle Pleistocene...
California’s next big one could be faster and far more destructive
Supershear earthquakes, moving faster than seismic waves, could cause catastrophic shaking across California. USC researchers warn that many faults capable of magnitude 7 quakes might produce these explosive ruptures. Current construction standards don’t account for their directional force. Stronger monitoring and building codes are urgently needed.
Closest alien civilization could be 33,000 light years away
Complex, intelligent life in the galaxy appears vanishingly rare, with the nearest possible civilization perhaps 33,000 light-years distant. Yet despite the odds, scientists insist that continuing the search for extraterrestrial intelligence is essential — for either outcome reshapes our understanding of life itself.
Scientists unearth a 112-million-year-old time capsule filled with ancient insects
Researchers have unearthed South America’s first amber deposits containing ancient insects in an Ecuadorian quarry, offering a rare 112-million-year-old glimpse into life on the supercontinent Gondwana. The amber, found in the Hollín Formation, preserved a diverse range of insect species and plant material, revealing a humid, resin-rich forest teeming with...
