Protein Assembly, Not Abundance, Explains Why Cells Behave So Differently
1+ day, 12+ hour ago (689+ words) For decades, biologists have treated protein abundance as the closest available proxy for what a cell is actually doing. Measure how much of each protein a cell produces, the reasoning went, and you have a reasonable snapshot of its functional…...
First NAM Population in Italian Ryegrass Pinpoints Genes Behind Seed
1+ day, 17+ hour ago (651+ words) Italian ryegrass (Lolium multiflorum Lam.) is one of the most important forage grasses in temperate agriculture, prized for its rapid growth, high digestibility and adaptability to intensive grazing and cutting systems. Yet behind its agronomic value lies a stubborn problem…...
Cryo-EM Captures Hidden Pre-Active State That Switches On the Brain’s
1+ day, 18+ hour ago (663+ words) For decades, neuroscientists have marveled at the sheer speed of communication in the brain, and much of that speed depends on a single family of proteins known as AMPA receptors....
Bird Guts Are a Dead End for Stick Insect Eggs, Digestion Experiments
2+ day, 7+ hour ago (793+ words) Stick and leaf insects are among the most accomplished masters of disguise in the animal kingdom, but their most remarkable imitation may be the one nobody watches happen. The eggs of many phasmid species look uncannily like plant seeds, complete…...
New Model Maps Brain Reaction Networks with Anatomical Precision
4+ day, 5+ hour ago (54+ words) In a development that could reshape how neuroscientists model the way external stimuli ripple through the brain, a new study published in the journal Neuroinformatics introduces a method that does something unusually ambitious: instead of assuming a fixed brain network…...
Plant Cross-Incompatibility Limits Genome Exchange and Gene Pool
2+ week, 5+ day 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…...
Pepper Study Links Ultra-Long Centromere Haplotypes to Evolution and
2+ week, 5+ day 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…...
Schisandrin Lignans Stabilize GPX4 to Suppress Ferroptosis in Drug-Induced
3+ week, 6+ day ago (57+ words) Drug-induced liver injury, one of the most unpredictable complications of modern pharmacotherapy, may be driven by a molecular failure that scientists are now learning to prevent. A study by Lan, Zheng, Li and colleagues reports that schisandrin lignans—bioactive compounds…...
