Phys.org / LHAASO discovers new extreme particle accelerator in the Milky Way
The Large High Altitude Air Shower Observatory (LHAASO) has made a breakthrough in exploring the extreme universe. For the first time, the LHAASO collaboration has detected ultra-high-energy (UHE) gamma rays—with energies ...
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 / CRISPR speed patterns can identify multiple viruses and variants simultaneously
As the spread of infectious diseases accelerates, technologies that can accurately distinguish multiple viruses in a single test are becoming increasingly important. KAIST and an international research team have developed ...
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 / 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 / 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 / Tiny fossil shells hold two chemical signals that could skew past ocean temperatures
Tiny plankton shells used to reconstruct past polar ocean temperatures may contain two different chemical stories, a new study by iC3 researchers has found. The work shows that Neogloboquadrina pachyderma, a key species in ...
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 / 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 / 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.
