Footprints found in the ancient lakebeds of White Sands may prove that humans lived in North America 23,000 years ago -- much earlier than previously believed. A new study using radiocarbon-dated mud bolsters earlier findings, making it the third ...

Scientists have uncovered a surprising new way that urea--an essential building block for life--could have formed on the early Earth. Instead of requiring high temperatures or complex catalysts, this process occurs naturally on the surface of tiny .. ...

Parts of New Orleans are sinking at alarming rates -- including some of the very floodwalls built to protect it. A new satellite-based study finds that some areas are losing nearly two inches of elevation per year, threatening the effectiveness of .. ...

Beneath the Afar region in Ethiopia, scientists have discovered pulsing waves of molten rock rising from deep within the Earth -- a geological heartbeat that could eventually split Africa in two. These rhythmic surges of mantle material are helping . ...

For over half a billion years, Earth's magnetic field has risen and fallen in sync with oxygen levels in the atmosphere, and scientists are finally uncovering why. A NASA-led study reveals a striking link between deep-Earth processes and life at the ...

At current emission rates, we re just over three years away from blowing through the remaining carbon budget to limit warming to 1.5 C. This new international study paints a stark picture: the pace of climate change is accelerating, seas are rising . ...

Remove the top male spotty fish and, within minutes, the next-in-line female morphs into the tank s new tyrant charging and nipping rivals while her body quietly begins a weeks-long transition to male.

A groundbreaking study suggests that the famous Cambrian explosion--the dramatic burst of diverse animal life--might have actually started millions of years earlier than we thought. By analyzing ancient trace fossils, researchers uncovered evidence . ...

Zooplankton like copepods aren't just fish food--they're carbon-hauling powerhouses. By diving deep into the ocean each winter, they're secretly stashing 65 million tonnes of carbon far below the surface, helping fight climate change in a way ...

At Flinders University, scientists have cracked a cleaner and greener way to extract gold--not just from ore, but also from our mounting piles of e-waste. By using a compound normally found in pool disinfectants and a novel polymer that can be reused ...
