Phys.org / Feeding shift may have steered 55 pilot whales toward Scotland mass stranding
New research, focused on the feeding behavior of long-finned pilot whales, has shed light on one of Scotland's largest mass stranding events. The study, led by the Scottish Marine Animal Stranding Scheme (SMASS) based at ...
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 / 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 / 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 / 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 / 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 / Hidden 3D atomic structure of relaxor ferroelectrics revealed for first time
Materials called relaxor ferroelectrics have been used for decades in technologies like ultrasounds, microphones, and sonar systems. Their unique properties come from their atomic structure, but that structure has stubbornly ...
Phys.org / Captured mid-reaction, RNA polymerase reveals universal blueprint for gene transcription
The enzyme RNA polymerase (RNAP) carries out transcription, copying DNA into RNA. It's the first step in gene expression, and a process fundamental to all life. But the inner workings of this essential enzyme have long baffled ...
Phys.org / A hidden food boom across Central Africa is pushing wildlife and rural diets toward a precarious edge
The total annual biomass of wild meat consumed across Central Africa has increased from an estimated 0.73 million metric tons in 2000 to 1.10 million metric tons in 2022. This increase is threatening wildlife populations ...
Phys.org / Hemp-based thermoplastic offers a greener alternative to plastic packaging
As the global pollution crisis caused by manufacturing and disposing of single-use plastics continues to grow, researchers have developed a non-toxic plastic alternative derived from the hemp plant—a non-psychoactive type ...
Phys.org / How mass extinctions helped termites become essential engineers of today's tropical ecosystems
Tropical ecosystems rely on the infrastructure provided by termites. These insects supply plants with vital nutrients by breaking down organic waste, bringing water to the roots by aerating the soil through tunneling, and ...
Phys.org / Western US is fending off more fires before they start—and still getting hit by its biggest blazes yet
The number of wildfires burning in the Western United States each year dropped roughly 28% over the past three decades, even as annual burned area and damage from wildfires have soared. A decline in fires accidentally sparked ...
