Making uniform decisions to justify the decommissioning of offshore artificial structures at the end of their lives could pose significant environmental challenges, a new study has said.
Evidence of Ice Age human migrations from China to the Americas and Japan
Scientists have used mitochondrial DNA to trace a female lineage from northern coastal China to the Americas. By integrating contemporary and ancient mitochondrial DNA, the team found evidence of at least two migrations: one during the last ice age, and one during the subsequent melting period. Around the same time...
Kangaroo Island ants ‘play dead’ to avoid predators
They're well known for their industrious work, but now a species of ant on Kangaroo Island is also showing that it is skilled at 'playing dead', a behavior that researchers believe is a recorded world first.
UC Irvine, NASA JPL Researchers Discover a Cause of Rapid Ice Melting in Greenland
While conducting a study of Petermann Glacier in northwest Greenland, researchers at the University of California, Irvine and NASA’s Jet Propulsion Laboratory uncovered a previously unseen way in which the ice and ocean interact.
Poor Mental Health in Medicine About More Than Just Doctors and Nurses, U of G Finds
In the early months of COVID-19, the nightly refrain of people banging pots and pans to drum up support for doctors and nurses on the frontlines of what would become a full-blown pandemic echoed around the world, a familiar sound of gratitude at a time when so much was unknown.
Tracking Whales as They Cruise the Arctic
Fibre-optic cables line the coasts of the continents and criss-cross the oceans, carrying signals that are the backbone of communication in the modern world.
Viruses could reshuffle the carbon cycle in a warming world
The roles microbes play in ecosystems are changing with global warming. Microbes are also affected by infection by viruses, but scientists know relatively little about how these viral infections could change how microbes react to warming. In this study, scientists describe different ways that increasing temperatures could affect viruses and...
Cleanup of inactive Gulf of Mexico wells estimated at $30 billion
A new article examines the cost to plug 14,000 wells that are inactive, have not produced for five years and are unlikely to be reactivated in the Gulf of Mexico region, which is the epicenter of U.S. offshore oil and gas operations.
Scientists develop gene silencing DNA enzyme that can target a single molecule
Researchers have developed a DNA enzyme -- or DNAzyme -- that can distinguish between two RNA strands inside a cell and cut the disease-associated strand while leaving the healthy strand intact. This breakthrough 'gene silencing' technology could revolutionize the development of DNAzymes for treating cancer, infectious diseases and neurological disorders.
Pollen Production Could Impact Climate Change by Helping Clouds Form
For millions of people with seasonal allergies, springtime means runny noses, excessive sneezes and itchy eyes.
