Phys.org / Heat and cold alter how animals fight disease. As the climate changes, this knowledge may be vital
Each animal species has an optimal temperature at which it can metabolize food and its immune system can best fight off pathogens.
Phys.org / RNA-built droplets create customizable organelles inside living cells
Just as the human body relies on organs such as the heart or liver for essential functions, cells depend on their own tiny organs, or organelles, to carry out vital tasks, including transporting nutrients, removing waste, ...
Phys.org / Lithium in the Appalachians could replace imports for a century or more, estimates suggest
The southern Appalachians hold an estimated 1.43 million metric tons of lithium oxide, concentrated in the Carolinas, and the northern Appalachians hold an estimated 900,000 metric tons, concentrated in Maine and New Hampshire, ...
Phys.org / Kangaroos chart 'upside-down' evolution
New research led by Flinders University argues thick tooth enamel helped kangaroos chart an unconventional evolution story, compared to the animals of other continents. A 50-million-year natural "experiment" among Australia's ...
Phys.org / Medieval images may have triggered imagined soundscapes, reshaping how viewers experienced saints
In cathedrals, such as Canterbury Cathedral in England, colorful stained glass and illustrated hagiographies tell the stories of saints through vivid visual narratives, inviting viewers into richly detailed scenes. Sometimes, ...
Phys.org / Rare Tyrian purple reveals elite Roman infant burials in York
Two infants buried in Roman York were laid to rest in costly purple cloth normally reserved for emperors and members of the aristocracy, new research reveals. The babies were wrapped in a fine textile of Tyrian purple embellished ...
Phys.org / One overlooked mineral may have quietly powered a crucial step toward life on early Earth
Manganese dioxide can convert amino acids into hydrogen cyanide (HCN) without requiring methane, a finding that solves a long-standing puzzle about the origin of this key prebiotic molecule on early Earth. Although HCN is ...
Phys.org / Massive reef expansion 20 million years ago may explain modern coral life's origins
New research published in Science Advances reveals that the largest expansion of coral reefs in the past 100 million years happened about 20 to 10 million years ago, between Australia and Southeast Asia.
Phys.org / Fungi utilize ancient antimicrobial proteins to attack hosts and their microbiomes, plant researchers discover
An international research team led by Cologne-based plant scientist Professor Dr. Bart Thomma from the Institute for Plant Sciences, the Collaborative Research Center MiBiNet and the CEPLAS Cluster of Excellence for Plant ...
Phys.org / Snow cover on Greek mountains has more than halved in four decades, study finds
Snow cover in the mountains of Greece—an important water source for communities, agriculture and natural ecosystems during the dry summer months—has more than halved over the past four decades, a study has found.
Phys.org / Malaria parasite sneaks mRNA into immune cell nuclei, disrupting defenses
RNA technology is regarded as one of the newest frontiers in medicine, but in fact a primordial innovator got there way before we did. The malaria parasite, an ancient single-celled organism, has been using sophisticated ...
Phys.org / Light-activated protein illuminates when embryos can cope with disruptions to cell division
Cell division during the early stage of embryo development is a trade-off between speed and accuracy; the cells need to divide quickly to enable rapid growth, but it's important not to introduce errors that could be fatal ...
