Phys.org / Southern Ocean intermediate waters may hold key to Earth's carbon dioxide history
Researchers at National Taiwan University and partner institutions have uncovered new evidence that Antarctic Intermediate Water (AAIW)—a distinct layer sitting 500–1,500 meters below the ocean surface—played a pivotal role ...
Phys.org / Worker bumble bees help determine which baby bee will become queen
Every bumble bee colony has a queen, but a new study led by researchers at Penn State suggests the process of determining which baby bee reigns supreme may be less monarchal than the royal title suggests. The study, published ...
Phys.org / 370 billion crickets are farmed for food every year. Scientists have discovered they may feel pain
You're cooking dinner, distracted, and your hand brushes a hot pan. Nerve signals race to your spinal cord and back to yank your arm away in a fraction of a second, with no thought required.
Phys.org / White hydrogen discovered in billion-year-old Canadian Shield rock points to potential new energy source
Within the Canadian Shield, hydrogen gas is steadily building up naturally among some of the oldest rocks on Earth. Now, for the first time, geochemists at the University of Toronto and the University of Ottawa have measured ...
Phys.org / Ancient Arctic fossils uncover three mammal species that survived months of darkness
Today's Arctic may feel remote and desolate, but more than 70 million years ago, it was a surprisingly lively place for some of Earth's ancient mammals.
Phys.org / AI-generated fake citations are flooding scientific literature across publications, scientists warn
The citations at the end of a research paper should represent a solid foundation of existing knowledge about a particular field, a pool of peer-reviewed sources built over years of research and study. However, with the increasing ...
Phys.org / Neanderthals gathered shellfish using the same strategies as modern humans, study finds
Neanderthal populations in southern Europe collected shellfish throughout the year, with a marked preference for the colder months, according to a new international study led by researchers from the Institute of Environmental ...
