Three billion years ago, Earth's life relied on a rare metal

A collaborative team of scientists has discovered that life on Earth over three billion years ago relied on the metal molybdenum, which was incredibly scarce in the environment at the time. The study, published in Nature ...

Under crushing hypergravity, fruit flies adapt—and recover

Expose an animal to extreme physical stress, and the expectation is simple: It will break down. But when UC Riverside scientists subjected fruit flies to forces many times stronger than Earth's gravity—a condition called ...

Astronomers find an exo-Jupiter, and it seems to have clouds

A team of astronomers led by Elisabeth Matthews at the Max Planck Institute for Astronomy (MPIA) has made a discovery that highlights the limits of most current models of exoplanet atmospheres: water-ice clouds on a distant ...

Which types of civilizations collapse and which can endure?

Human history is littered with expired civilizations, and scholars and archaeologists have made a determined effort to understand why and how civilizations collapse. They've found that symptoms like a growing wealth gap and ...

New device aims to protect the Earth from Martian microbes

The possibility of life on other planets is one of the biggest mysteries in science. But what would happen if we actually found it? Our scientists are preparing for this possibility by helping to develop a new system that ...

How resilient fungus might survive Mars and space

Scientists have long known that fungi are resilient, but a new study suggests that some strains might survive every step of the long, brutal trip to Mars. In a paper published in Applied and Environmental Microbiology, researchers ...

'Bathtub ring' hints at ancient Martian ocean

Caltech researchers have identified geological features on Mars that could point to the existence of a long-dried ocean that once covered a third of the Red Planet's surface. The research was conducted by former Caltech postdoctoral ...
