Biologists Sequence Iberian Ribbed Newt Genome at High Resolution
Aquatic, tailed amphibians called newts have large genomes harboring many repeat elements. How these elements shape the genome and relate to newts’ unique regeneration ability remains unknown. In new research, scientists from Karolinska Institute and elsewhere produced a chromosome-scale genomic sequence for the Iberian ribbed newt (Pleurodeles waltl). Brown et al. present the chromosome-scale assembly
Repeating Fast Radio Burst Traced to Outskirts of Quiescent Elliptical Galaxy
The source of the newly-detected fast radio burst, FRB 20240209A, is in the distant outskirts of an ancient elliptical galaxy, which is located 2 billion light-years from Earth and has a mass of more than 100 billion solar masses. Young stellar remnants that theorists think produce such bursts of radio waves should have disappeared long

GPT-Fabricated Scientific Papers Flood Google Scholar, Scientists Say
In a new study published in the Harvard Kennedy School Misinformation Review, researchers from the University of Borås, Lund University and the Swedish University of Agricultural Sciences found a total of 139 papers with a suspected deceptive use of ChatGPT or similar large language model applications; out of these, 19 were in indexed journals, 89
New Species of Ankylosaur Identified in China
A new genus and species of ankylosaurid dinosaur has been identified from the fossilized material found at Kangdailiang Mountain (1,262 m above sea level) in China. Two ankylosaurs.
