How asteroids may have sparked life on Earth

Ancient asteroid impacts may have done more than reshape Earth's surface—they could have helped spark life itself. New computer models show the collisions created enormous underground hydrothermal systems by cracking the planet's crust and allowing hot water to flow through it. T

Sightings of humpback whales surge in Rio de Janeiro, fueling demand for whale-watching tr

Sightings of humpback whales off Rio de Janeiro's coast are surging as they recover from decimation due to commercial whaling, prompting an acceleration in the demand for whale-watching excursions to spot the huge marine creatures during their annual migration.

Voyage to the end of the world: floating lab to explore life in Arctic adrift in ice

An eight-month expedition will set off soon from Norway on a mission to find new species before the climate crisis and pollution changes the northern ocean for everSix scientists and six crew will travel next month to Kirkenes, a remote Arctic town in Norway near the Russian bord

Harsh UVB bursts leave tadpoles with more DNA damage than longer exposure

Sunburn is a serious problem in the Southern Hemisphere, where depleted ozone provides less protection from UVB. Tadpoles are at particular risk because they are growing rapidly, making them vulnerable to UVB DNA damage. Niclas Lundsgaard of The University of Queensland (UQ), Aus

AI could bring satellite crop monitoring to the world's most vulnerable farms

Small farms grow much of the world's food, but from space they are nearly invisible. Their fields are tiny and ill-defined, and the satellite tools built to track crops were designed for the large, uniform fields of industrial agriculture, not the sub-hectare plots that feed many

Comet from another star has a composition unlike anything else in our solar system

Astronomers have revealed new details about the makeup and age of a visiting comet that was born around a distant star. They conclude that the composition of 3I/Atlas is strikingly different from any object found in our solar system.

Dynamic black holes may obey Hawking-style thermodynamics with an alternative entropy meas

Of the known things in the universe, black holes are among the most extreme. They pack huge amounts of mass densely into a small area, producing gravity that is so strong that even light cannot escape. To describe their properties, physicists have relied on complex equations from

MOF thin films reveal hidden dense packing, challenging decades of porous assumptions

Due to their high porosity, metal-organic frameworks (MOFs) are regarded as promising materials for innovative applications, which is why the Nobel Prize in Chemistry was awarded in 2025 for their discovery. They are used, for example, to store gases, to capture CO2 and for the t

How giant tropical trees transport water 70 meters to stay as drought-resilient as smaller

The giant trees of tropical forests are important allies in the fight against climate change because of their ability to store carbon, yet they are still poorly understood by science. However, a study published in the journal Science reveals a crucial survival mechanism: These tr

Deliberate slow growth could explain bacteria survival strategies

Escherichia coli (E. coli) are mostly harmless bacteria that live in the intestines of animals and humans. They are the most well-studied bacteria and, often, when scientists discover something about E. coli, they extrapolate that discovery across all bacteria. So when scientists

A WRAP for biology's greasiest problem

Embedded in the boundary between the inside and outside of each cell are membrane proteins. They act as first responders by sensing signals, regulating which molecules enter and leave the cell, and enabling cells to quickly adapt to changes in their environment.
