Little red dots have puzzled astronomers since their discovery in James Webb Space Telescope (JWST) data from the universe's deep past. Their "powering engines" might resemble a newly discovered phenomenon dubbed a "black hole star"—an early, rapidly growing black hole wrapped in dense gas. This object, described in a study published today in Nature by researchers at the Institute of Science and Technology Austria (ISTA) and international collaborators, may help explain how billion-solar-mass black holes formed so soon after the Big Bang.

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.
