A Disturbing Process Has Been Accelerating in Freshwater Lakes Worldwide, Study Finds

On top of intensifying algal blooms and depleting oxygen, a new study reveals Earth's bodies of freshwater are also evaporating at a greater rate than we realized. What's more, "lake evaporation plays a larger role in the hydrological cycle than previously thought," says ecologist Gang Zhao who was at Texas A&M University during the study. This process thus has a substantial impact on our climate and weather modeling.

Mars Has So Much Radiation, Any Signs of Life Would Be Buried Six Feet Under

The search for life on Mars may have just gotten a whole lot more complicated. While rovers such as Curiosity and Perseverance scour the surface looking for traces of ancient life, new evidence reveals we may have to dig much deeper to find them. Any evidence of amino acids left over from a time when Mars may have been habitable are likely buried at least 2 meters (6.6 feet) under the ground. That's because Mars, with its lack of magnetic field, and flimsy atmosphere, is subject to a much higher dose of cosmic radiation on its surface than Earth is. We know...

'Cradle of Humankind' Fossils May Be a Million Years Older Than Previously Thought

Multiple ancient hominin remains from caves in South Africa may be much, much older than previous estimates suggested. The Sterkfontein limestone cave system, not far from Johannesburg, has yielded so many ancient bones from the hominin genus Australopithecus over the last century that its location has been dubbed the Cradle of Humankind – deeply important to the study of human evolution.

Voids Made by Dying Stars Have Been Detected in Our Galaxy's Interstellar Gas

It often feels like when people die, they leave a void behind. In the case of massive stars, that happens to be physically true. A new analysis of the tenuous gas that drifts between the stars in the Milky Way galaxy has revealed the imprint of bubbles that expand into space when a massive star goes supernova at the end of its life. These ghostly traces, scientists say, record a history of star death and the rotation of the Milky Way.

The Deep Ocean Might Store Way Less Carbon Than We Hoped

The oceans are one of our planet's most important carbon sinks, with currently around 39,000 gigatons of carbon dioxide locked away – that's around 50 times more than what's circulating in the atmosphere right now. However, we can't rely on this carbon capture and storage to solve our climate...

These Toadlets Are So Tiny They Can't Balance Anymore, And The Footage Is Ridiculous

Being tiny can certainly have its advantages. You need less food, don't take up as much space, and are harder for predators to spot. But researchers have just discovered there's a limit to how small a backboned animal can get, while still retaining the ability to balance. Pumpkin toadlets (Brachycephalus) have miniaturized well beyond this limit, resulting in hilariously awkward acrobatics whenever they try to leap.
