Collagen Switch Turns Fish Fins Into Limb-Like Structures

just now (83+ words) When the first fish lineage crawled onto land some 375 million years ago, its fins had to be remodeled into limbs capable of bearing weight. Evolutionary biologists have long focused on the genes that pattern the skeleton—Hox clusters, Sonic hedgehog,…...

Google's mapped fruit fly brain has played Doom more than 6,000 times and still hasn't beaten it

12+ hour, 1+ min ago (168+ words) Google mapped the complete brain and central nervous system of an adult male fruit fly, reconstructing more than 166,000 individual neurons. Google's fully mapped fruit fly brain is barely a week old, and it's already been put to work doing what…...

New Rust Toolkit Supercharges Sex Determination Studies in Non-Model

1+ hour, 9+ min ago (628+ words) A new open-source software package promises to transform how biologists hunt for the genetic switches that separate males from females in species with no reference genome....

Mole-Rat Genes Evolving Faster Than Expected Reveal Secrets of Subterranean

1+ hour, 32+ min ago (568+ words) Beneath the sun-baked soils of eastern and southern Africa, a family of rodents has quietly rewritten the rules of mammalian life. Naked mole-rats resist cancer, tolerate near-anoxic conditions and barely age. Damaraland mole-rats dig elaborate tunnel networks and live in…...

SIRT1 Silences Jumping Genes by Stabilizing Heterochromatin Complexes

1+ hour, 40+ min ago (55+ words) Deep within the human genome lies an ancient threat. Long interspersed elements-1, known as LINE-1 or L1, are the only autonomous transposable elements still active in our DNA, making up roughly 17 percent of the genome. When these genetic parasites leap to…...

Nanoparticles Emerge as a Powerful New Weapon Against Cellular Aging

2+ hour, 16+ min ago (87+ words) Cellular senescence, one of the most closely studied hallmarks of aging, has long been a paradox in biology. On the one hand, it protects organisms by halting the division of damaged cells that might otherwise become cancerous. On the other,…...

Scientists Discover CD55 Is the Hidden Switch That Powers Natural Killer

2+ hour, 27+ min ago (680+ words) Natural killer cells have long been celebrated as the swift, unsung assassins of the immune system, capable of detecting and destroying tumor cells without the elaborate priming that T cells require....

Protein Assembly, Not Abundance, Explains Why Cells Behave So Differently

3+ hour, 6+ min 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…...

Goji Berry Polysaccharide Stabilizes Wheat Protein Foams in a

3+ hour, 45+ min ago (55+ words) Plant-based foods are booming, but one humble challenge keeps tripping up the industry: bubbles. The foams that give bread, cakes, plant-based whipped toppings, and cappuccino-style drinks their lightness are thermodynamically unstable dispersions of gas in liquid, and without animal-derived proteins…...

Orphan Bitter Taste Receptors Found on Cell Surfaces, Hinting at Hidden

3+ hour, 45+ min ago (83+ words) Bitterness is often dismissed as a nuisance of the dinner plate, the flavor note that makes children push away Brussels sprouts and coffee drinkers reach for sugar. Yet for evolutionary biologists and physiologists, the ability to detect bitter compounds is…...
