In many rivers, only a small amount of streamflow remains for nature after water is diverted for hydropower production. In light of climate change and biodiversity loss, this is having increasingly serious consequences. Researchers from WSL,...
Scientists have identified what could be the oldest rocks on Earth from a rock formation in Canada. The Nuvvuagittuq Greenstone Belt has long been known for its ancient rocks—plains of streaked gray stone on the eastern shore...

New unified theory shows how past landscapes drove the evolution of Earth’s rich diversity of life

Earth's surface is the living skin of our planet—it connects the physical, chemical and biological systems. Over geological time, this surface evolves. Rivers fragment the landscape...

How old is the universe exactly? A new theory suggests that it’s been around for twice as long as believed

Early universe observations by the James Webb Space Telescope (JWST) cannot be explained by current cosmological models. These models estimate the universe to be...

Scientists unveil a unified theory for rocky planet formation

A new theory for how rocky planets form could explain the origin of so-called "super-Earths"—a class of exoplanets a few times more massive than...

New theory concludes that the origin of life on Earth-like planets is likely

Does the existence of life on Earth tell us anything about the probability of abiogenesis—the origin of life from inorganic substances—arising elsewhere? That's a...

String theory: NASA Mars rover discovers mystery object

Is it tumbleweed? A piece of fishing line? Spaghetti? A tangled object discovered by NASA's Mars Perseverance rover has intrigued space watchers, leaving some musing...

Dark matter: Our review suggests it’s time to ditch it in favor of a new theory of gravity

We can model the motions of planets in the Solar System quite accurately using Newton's laws of physics. But in the early 1970s, scientists...

Martian meteorite upsets planet formation theory

A new study of an old meteorite contradicts current thinking about how rocky planets like the Earth and Mars acquire volatile elements such as...
