Collagen Switch Turns Fish Fins Into Limb-Like Structures
2+ hour, 51+ min ago (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,…...
Mussel Brains Reveal How Nervous Systems Survive Oxygen Starvation and
9+ hour, 35+ min ago (671+ words) When the tide recedes from a rocky Mediterranean shore, the mussels clinging to the stones simply close their shells and wait. Inside those shells, oxygen levels plummet, carbon dioxide accumulates, and the entire body shifts into a biochemical holding pattern…...
Ichthyosaurs Had Surprisingly Dense Ribs, New Study Finds | Sci.News
1+ day, 12+ hour ago (267+ words) New research from the Natural History Museum at the University of Oslo suggests ichthyosaurs’ rib cages may have done a job modern whale ribs don’t: acting as ballast to help them dive....
Global Team Boosts Radiocarbon Dating with Marine Fossils
2+ day, 2+ hour ago (643+ words) Sedimentation is more important than other factors in the 'time averaging' of marine fossils The investigators analysed more than 7,500 fossils, which were collected from a variety of oceanic environments around the world ANSTO has contributed to a large international study…...
How can deep-sea organisms survive under extreme pressure?
2+ day, 12+ hour ago (180+ words) A research team, led by Professor Gaku Fukuhara of Kyushu University’s Institute for Materials Chemistry and Engineering (IMCE), investigated this biological phenomenon. They focused on PoXeR, a protein from a deep-sea bacterium. Using a custom-built apparatus, they subjected the protein…...

Under pressure: How a deep-sea protein adapts to an extreme environment
2+ day, 14+ hour ago (510+ words) Researchers uncover the molecular strategy that enables PoXeR, a light-driven protein found in deep-sea microorganisms, to adapt to extreme pressure A research team, led by Professor Gaku Fukuhara of Kyushu University’s Institute for Materials Chemistry and Engineering (IMCE), investigated this…...
Nearly Destroyed DNA Reveals Two Extinct Giant Tortoise Lineages
3+ day, 3+ hour ago (119+ words) Using a new computational toolkit, Yale researchers recovered evolutionary clues from highly degraded DNA and identified two extinct lineages of giant tortoises....
Scientist stumbles across massive ancient tooth while surveying a San Mateo County preserve
3+ day, 6+ hour ago (402+ words) A scientist accidentally discovered a jaw-dropping Ice Age fossil –– an ancient molar tooth –– while conducting field surveys in San Mateo County. Brigid Lynch, a geomorphologist with Balance Hydrologics, was working on a project in a Midpeninsula Regional Open Space preserve…...
