Credit: Pixabay/CC0 Public Domain Discoveries of aquifers—underground earth formations that hold water—often create excitement around their ability to ease water scarcity in a region. For instance, about 10 years ago a large aquifer was discovered in Kenya’s Turkana region. This is one of the hottest, driest parts of Kenya and it frequently suffers from drought. […]

Lab experiments suggest oxygen in early Earth’s atmosphere may have come from rocks

Two proposed mechanisms for H2O2 generation at quartz–water interfaces. (A) Stress-induced cleavage of Si–O bonds. Applied force is represented by a linear falling potential (dashed line), which is added to the Morse potential of the unstretched Si–O bond (dotted line), thus resulting in a force-deformed Morse potential (solid line). The new dissociation energy D′ is […]

Astronomers analyze first results from ESO telescopes on the aftermath of DART’s asteroid impact

This series of images, taken with the MUSE instrument on ESO’s Very Large Telescope, shows the evolution of the cloud of debris that was ejected when NASA’s DART spacecraft collided with the asteroid Dimorphos. The first image was taken on 26 September 2022, just before the impact, and the last one was taken almost one […]

Molecular teamwork makes the organic dream work

Credit: Pixabay/CC0 Public Domain The virus responsible for E. coli infection has a secret weapon: teamwork. Always scrappy in its bid for survival, the virus alights on an unassuming host cell and grips the surface with the business end of its tubular tail. Then, the proteins in the tail contract in unison, flattening its structure […]

How the ‘marsupial sabertooth’ thylacosmilus saw its world

A reconstruction of Thylacosmilus atrox. Credit: © Jorge Blanco A new study investigates how an extinct, carnivorous marsupial relative with canines so large they extended across the top of its skull could hunt effectively despite having wide-set eyes, like a cow or a horse. The skulls of carnivores typically have forward-facing eye sockets, or orbits, […]

Scientists make ‘disturbing’ find on remote island: plastic rocks

A ‘plastic rock’ found by Brazilian scientists on Trindade Island,one of the most remote places on the planet. There are few places on Earth as isolated as Trindade island, a volcanic outcrop a three- to four-day boat trip off the coast of Brazil. So geologist Fernanda Avelar Santos was startled to find an unsettling sign […]
