Crocodile evolution rebooted by Ice Age glaciations
Crocodiles are resilient animals from a lineage that has survived for over 200 million years. Skilled swimmers, crocodiles can travel long distances and live in freshwater to marine environments. But they can't roam far overland. American crocodiles.....»»

Green hydrogen: MXenes show talent as catalyst for oxygen evolution reaction
The MXene class of materials has many talents. An international team led by HZB chemist Michelle Browne has now demonstrated that MXenes, properly functionalized, are excellent catalysts for the oxygen evolution reaction in electrolytic water splitti.....»»
Angiosperms study provides insights into genome evolution after whole-genome duplications
Whole-genome duplication (WGD, or polyploidy) is a common and frequent occurrence in plants, providing raw genetic material for evolution. Homoeologs (duplicate genes from a WGD) often diverge in expression levels, while some still maintain similar (.....»»

Double-peaked supernovae offer clues to pre-supernova outbursts
New research helps in understanding the evolution and final stages of massive stars, the role of binary interactions, and the mechanisms behind mass loss, which ultimately affect the properties of the resulting supernova and its remnant. This work al.....»»
Tuberculosis under the sea: A marine sponge microbe provides insights into the bacterium"s evolution
The surprising discovery of a bacterium in a marine sponge from the Great Barrier Reef with striking similarity to Mycobacterium tuberculosis, the pathogen responsible for tuberculosis (TB), could unlock and inform future TB research and treatment st.....»»
Spectroscopy study reveals electrons in cocatalyst periphery drive photocatalytic hydrogen evolution
Synchronizing periodic excitations of photocatalysts with a Michelson interferometer on operando FT–IR spectroscopy, researchers led by Toshiki Sugimoto succeeded in observing and identifying the reactive electron species for photocatalytic hydroge.....»»
Larger ant colonies drive the evolution of worker castes: Division of labor is key to life"s complexity, says study
Just like human societies, ant societies have a division of labor. Within a colony, some individuals feed the young while others are soldiers who protect the colony from intruders. New research across 794 ant species, published in Nature Ecology & Ev.....»»
Land-sea "tag-team" devastated ocean life millions of years ago, reveal scientists
Scientists have revealed how a "tag-team" between the oceans and continents millions of years ago devastated marine life—and altered the course of evolution on Earth......»»
Ancient sea cow that was attacked by both a primeval crocodile and shark sheds new light on prehistoric food chains
A new study showing how a prehistoric sea cow was preyed upon by not one, but two different carnivores—a crocodilian and a shark—is revealing clues into both the predation tactics of ancient creatures and the wider food chain millions of years ag.....»»
From rhino horn snuff to pangolin livestock feed: A half-century of patents reveals the wildlife trade"s evolution
