A new study from the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science and the Marine Megafauna Foundation finds that young Caribbean manta rays (Mobula yarae) often swim with groups of other ...
Phys.org / New biomolecular technique uncovers millet in medieval Ukrainian dental calculus
A study has, for the first time, identified minute traces of broomcorn millet consumption directly from human dental calculus, offering an unprecedented window into medieval diets and expanding the toolkit available to archaeologists ...
Phys.org / Recent H5N1 bird flu variants show increased ability to infect dairy cattle
The H5N1 avian influenza virus—commonly known as bird flu—has been causing outbreaks in dairy cows in the United States since March 2024. Now, scientists studying the adaptation of the avian H5N1 viruses to cows have ...
Phys.org / Molecules as switches for sustainable light-driven technologies
Metal nanostructures can concentrate light so strongly that they can trigger chemical reactions. The key players in this process are plasmons—collective oscillations of free electrons in the metal that confine energy to ...
Phys.org / Climate shapes arms race between ants and their social parasites
Two new studies show how climate influences behavior, communication, and genome evolution—driving adaptation in a long-running conflict.
Phys.org / Nanoscale magnetic mazes could transform data center communications
A collaborative team has developed a new way to create magnetic optical materials, one that removes a long-standing design bottleneck and could boost the speed and efficiency of data-center communications. Using an ion beam ...
Phys.org / The Alps set to lose a record number of glaciers in the next decade, study warns
Glaciers are melting worldwide. In some regions, they could even disappear completely. Looking at the number of glaciers disappearing, the Alps could reach their peak loss rate as early as 2033 to 2041. Depending on how sharply ...
Phys.org / Bayeux Tapestry could have been originally designed as mealtime reading for medieval monks
New research by a historian from the University of Bristol offers an intriguing suggestion about one of history's biggest mysteries—the original purpose of the world-famous Bayeux Tapestry.
Phys.org / Interstellar comet keeps its distance as it makes its closest approach to Earth
A stray comet from another star swings past Earth this week in one last hurrah before racing back toward interstellar space.
Phys.org / Amazon could lose over a third of forest cover by century's end
A new LMU study estimates that land use changes in conjunction with climate change could lead to the loss of up to 38% of the Amazon rainforest by the end of the 21st century.
Phys.org / Social connections slow aging in dolphins, echoing patterns seen in humans
Male bottlenose dolphins that form friendships age more slowly than loners, new research shows.
Phys.org / Study uncovers new drug target for huge class of viruses
A study from the University of Maryland, Baltimore County (UMBC), published in Nature Communications, reveals how enteroviruses—including pathogens that cause polio, encephalitis, myocarditis, and the common cold—initiate ...
