cGAS-Deficient Mice Show Premature Aging Linked to LINE1 Derepression and
1+ hour, 7+ min ago (752+ words) A new study published in Nature Aging reports that mice lacking the enzyme cGAS develop signs of premature aging, accompanied by the abnormal activation of repetitive genetic sequences known as LINE1 elements and a rise in inflammation....
Koala Populations Show Geographic Variation in Toll-Like Receptor Diversity
5+ hour, 42+ min ago (733+ words) Koalas may carry more genetic variation in a crucial first line of immune defence than previously recognised, according to a new study of 413 wild animals sampled across eastern Australia....
Plant Cross-Incompatibility Limits Genome Exchange and Gene Pool
9+ hour, 3+ min ago (878+ words) Crop wild relatives may hold the genetic tools needed to help agriculture withstand drought, heat, salinity, emerging diseases and increasingly unstable growing conditions. Yet the same evolutionary distance that preserved these valuable traits often prevents breeders from moving them into…...
East German Plant Genetics Pioneer Thomas Börner Celebrates 80th Birthday
9+ hour, 11+ min ago (684+ words) A scientist who conducted molecular genetics research behind the Iron Curtain, built international collaborations before German reunification, and helped reveal how chloroplasts communicate with the cell nucleus is being celebrated as one of Germany’s pioneering plant geneticists. Professor Thomas Börner,…...
Pepper Study Links Ultra-Long Centromere Haplotypes to Evolution and
13+ hour, 32+ min ago (54+ words) Pepper plants may be hiding some of their most consequential genetic variation in regions long treated as difficult, repetitive stretches of DNA. A study published in Nature Ecology & Evolution reports that ultra-long haplotypes surrounding pepper centromeres can extend across tens…...
Scientists characterize genetic variants across the human intrinsically
13+ hour, 55+ min ago (656+ words) Variant effect prediction has entered a new phase, but one of biology’s largest blind spots remains stubbornly difficult to resolve. Computational tools have become increasingly effective at estimating the consequences of missense variants in folded protein domains, where amino-acid positions…...
Neuromorphic bionic eye with dense waveguide pixels enables tunable-depth

Hypercontractile embryos from older female mice experience implantation
18+ hour, 30+ min ago (550+ words) A hidden mechanical failure inside the earliest stages of life may help explain why fertility declines so sharply as females enter their mid-30s. A study published in Nature Cell Biology reports that embryos from reproductively aged female mice are not simply…...
Single-cell RNA sequencing maps gonadal changes during sex reversal in
20+ hour, 23+ min ago (606+ words) A single-cell transcriptomic study of the orange-spotted grouper, Epinephelus coioides, is offering an unprecedented view of how a fish gonad reorganizes itself during hormone-induced sex reversal. The research focuses on a remarkable biological system: this species is a protogynous hermaphrodite,…...
Scientists Create Polycaprolactone-Based 2D Platelets Through Living
23+ hour, 39+ min ago (593+ words) A new polymer-assembly protocol is turning a familiar biodegradable polyester into precisely shaped two-dimensional nanomaterials. In a study published in Nature Protocols, Xia, Xiao, Yadav and colleagues describe how to prepare ultrathin poly(ε-caprolactone), or PCL, platelets whose lateral dimensions…...
