Researchers have found a clever new way to map a part of Earth’s upper atmosphere that is notoriously difficult to observe. Using orbital data from roughly 1,200 Starlink satellites, they reconstructed changes in atmospheric density about 500 kilometers above Earth. The approach could sharpen satellite tracking and help reduce the growing risk of collisions in increasingly crowded orbits.

Claim that science is becoming less disruptive challenged after years-long publication delay

A widely cited Nature cover article from 2023 claimed that scientific innovation has significantly declined in recent decades. This finding was based on a citation analysis of large sets of metadata concerning scientific papers and patents. Researchers from Vrije Universiteit Brussel (VUB) and KU Leuven have found that incomplete reference data account for most of the alleged decline in scientific disruption. Their article is also published in the journal Nature.

Microbes turn CO₂ into protein and vitamin B9 at commercially viable prices

Researchers are developing biotechnological processes that enable microbes to produce proteins and vitamins for human consumption using basic chemical ingredients, such as carbon dioxide, hydrogen and oxygen—entirely bypassing livestock farming and agriculture. Because these methods also require energy input, they are popularly called "power-to-protein" and "power-to-vitamin" processes.
