Trout living in rivers polluted by metal from old mines across the British Isles are genetically “isolated” from other trout, new research shows.
Historic iceberg surges offer insights on modern climate change
A great armada entered the North Atlantic, launched from the cold shores of North America. But rather than ships off to war, this force was a fleet of icebergs. And the havoc it wrought was to the ocean current itself. The future of the Atlantic circulation will be determined by...
People are altering decomposition rates in waterways
Humans may be accelerating the rate at which organic matter decomposes in rivers and streams on a global scale, according to a new study. That could pose a threat to biodiversity in waterways around the world and increase the amount of carbon in Earth's atmosphere, potentially exacerbating climate change. The...
‘Ugly’ fossil places extinct saber-toothed cat on Texas coast
This fossil looks like a lumpy, rounded rock with a couple of exposed teeth that are a little worse for wear, having been submerged and tumbled along the floor of the Gulf of Mexico for thousands of years before washing up on a beach. But when it was X-rayed a...
Researchers Improve Satellite Surveillance of Emperor Penguins
Monitoring the global population of emperor penguins is a major challenge.
Tornado Damage in Greenfield
In one of the busiest U.S. tornado seasons in years, National Weather Service meteorologists have confirmed 875 tornadoes as of May 28.
Improving Air Quality Increases Forest Fires
If we want cleaner air, fewer forest fires, and less severe climate change, a new UC Riverside study shows we must reduce aerosol pollution and greenhouse gases like carbon dioxide at the same time.
Musankwa sanyatiensis, a new dinosaur from Zimbabwe
Fossils found on the shoreline of Lake Kariba in Zimbabwe represent a completely new dinosaur species. This remarkable find, named Musankwa sanyatiensis, marks only the fourth dinosaur species named from Zimbabwe.
Editing without ‘cutting’: Molecular mechanisms of new gene-editing tool revealed
New research has determined the spatial structure of various processes of a novel gene-editing tool called 'prime editor.' Functional analysis based on these structures also revealed how a 'prime editor' could achieve reverse transcription, synthesizing DNA from RNA, without 'cutting' both strands of the double helix. Clarifying these molecular mechanisms...
Grow the skin you’re in: In vivo generation of chimeric skin grafts
Researchers found that mutated mouse embryos showing an abnormal epidermal differentiation and injected with mouse pluripotent stem cells grew large patches of mature epidermis derived from the donor cells that survived transplantation to adult mice and grew natural-looking fur. Injecting the embryos with human keratinoctyes produced sheets of semi-humanized skin,...
