Extreme events wipe out entire forests, dramatically eliminating complex ecosystems as well as local communities.
How T cells combat tuberculosis
Scientists have uncovered important clues to how human T cells combat Mycobacterium tuberculosis, the bacterium that causes TB.
Extra fingers and hearts: Pinpointing changes to our genetic instructions that disrupt development
Scientists can now predict which single-letter changes to the DNA within our genomes will alter genetic instructions and disrupt development, leading to changes such as the growth of extra digits and hearts. Such knowledge opens the door to predictions of which enhancer variants underlie disease in order to harness the...

A new species of pterosaur from specimens found on the Isle of Skye, Scotland, has been announced.
In a warming world, climate scientists consider category 6 hurricanes
For more than 50 years, the National Hurricane Center has used the Saffir-Simpson Windscale to communicate the risk of property damage; it labels a hurricane on a scale from Category 1 (wind speeds between 74 -- 95 mph) to Category 5 (wind speeds of 158 mph or greater). But as...
Study challenges the classical view of the origin of the Antarctic Circumpolar Current and warns of its vulnerability
The Circumpolar Current works as a regulator of the planet's climate. Its origins were thought to have caused the formation of the permanent ice in Antarctica about 34 million years ago. Now, a study has cast doubt on this theory, and has changed the understanding of how the ice sheet...
Number of shark bites consistent with recent trends, with small spike in fatalities
There was an increase in the number of unprovoked shark attacks worldwide and an uptick in fatalities in 2023 compared to the previous year. A scientific database of global shark attacks, confirmed 69 unprovoked bites in 2023. Although this is higher than the most recent five-year average of 63 attacks,...
Currently Stable Parts of East Antarctica May Be Closer to Melting Than Anyone Realized
Stanford researchers have found large thawed or close-to-thawed areas under coastal portions of the ice sheet that holds back glaciers in the Wilkes Subglacial Basin.
Longitudinal Study Links PFAS Contamination With Teas, Processed Meats and Food Packaging
Researchers from the Keck School of Medicine of USC studied how dietary patterns relate to levels of so-called forever chemicals in the body over time.
Vitamin B12 Adaptability in Antarctic Algae Has Implications for Climate Change
Vitamin B12 deficiency in people can cause a slew of health problems and even become fatal.
