More than 60 years after it was first spotted, Cygnus X-1 — the first confirmed black hole — is still full of surprises. Researchers have finally measured the energy output of this behemoth’s “dancing jets,” and the results could help answer wider questions about the extreme behavior of black holes, experts say. Cygnus X-1 is…
CAPE CANAVERAL, Fla. (AP) — For the first time, scientists have measured the instantaneous mind-blowing power of jets blasting from a black hole. The jet power from this relatively close black hole-star system is equivalent to 10,000 suns, an international research team reported Thursday. They also tracked the jet speed: roughly 355 million mph (540…
Research has shed important new light on the enemies-turned-allies that allow bacteria to exchange genes, including those linked to antimicrobial resistance (AMR). The insights, which expand our understanding of the major global health threat of AMR, came as John Innes Center researchers investigated the curious phenomena of gene transfer agents (GTAs).

Madeleine Finlay sits down with co-host and science editor Ian Sample to discuss three eye-catching stories from the week, including a review into the effectiveness of a new class of Alzheimer’s drug that was once hailed as a game-changer in slowing the progress of the disease. Also on the agenda is the news that the…
Ammonia pollution hotspots have been identified in areas with some of the greatest numbers of intensive pig and poultry farms in Britain, research has revealed. A new map for the first time reveals the most severe concentrations of ammonia emissions are clustered in Lincolnshire, Herefordshire and Norfolk. These regions all have a high density of…
Red foxes and birds regularly cross between human-dominated and natural ecosystems. For this reason, they may be heralds of spreading antibiotic resistance into ecosystems unexposed to antibiotic pressures, a study done in Italy showed. Results indicated that the share of K. pneumoniae isolates resistant to third-generation cephalosporins—a key group of hospital antibiotics—was about five times…
Proceedings of the National Academy of Sciences, Volume 123, Issue 15, April 2026. <br/>SignificanceThe drug delivery efficiency of engineered nanocarriers depends critically on their stability in biological media. Here, we introduce the stabilization enthalpy concept to describe experimentally determined thermodynamic stability relations of … Source: Read Full Article
In a remote part of northern Mauritania on the Adrar Plateau lies a desert landscape rich in human history. This region of northwestern Africa is sprinkled with Paleolithic stone tools, Neolithic cave paintings, and the remains of medieval towns once used by caravans crossing the Sahara Desert. When viewed from space, the landscape appears to…
Humans like to think we sit at the top of the evolutionary ladder, largely because we have language, which is a system so flexible and expressive that it’s often taken as proof of our intelligence. However, whales may complicate that assumption. Researchers have suspected for years that whales might be using a far more sophisticated…
