Combining atomic-scale sample analysis and models simulating likely conditions in the nascent solar system, the study revealed clues about the origin of crystals that formed more than 4.5 billion years ago. The findings provide insights into the fundamental processes underlying the formation of planetary systems, many of which are still shrouded in mystery.

For the study, the team developed a new type of framework, which combines quantum mechanics and thermodynamics, to simulate the conditions to which the grain was exposed duri...

A new study suggests that unrepaired DNA damage can increase the speed of aging. Every day, our bodies face a bombardment of UV rays, ozone, cigarette smoke, industrial chemicals and other hazards.

This exposure can lead to free-rad...

Scientists have used a compound made from a starch derivative and baking soda to help convert mechanical to electrical energy. The approach, developed by scientists at Daegu Gyeongbuk Institute of Technology (DGIST), with colleagues in Korea and India, is cost-effective and biocompatible, and can help charge low-energy electronics like calculators and watches. The details were published in the journal Advanced Functional Materials.

“Triboelectric nanogenerators harvest mechanical energy and convert it into an electric current,” explains DGIST robotics engineer Hoe Joon Kim...

A new analysis of Venus’ surface shows evidence of tectonic motion in the form of crustal blocks that have jostled against each other like broken chunks of pack ice. The movement of these blocks could indicate that Venus is still geologically active and give scientists insight into both exoplanet tectonics and the earliest tectonic activity on Earth.

“We’ve identified a previously unrecognized pattern of tectonic deformation on Venus, one that is driven by interior motion just like on Earth,” sa...
