Phys.org / Scientists find molecular-level evidence for two structures in liquid water
A study published in Nature Physics provides new molecular-level evidence from simulations that liquid water is not a single uniform substance, but a constantly shifting mixture of two distinct microscopic structures.
Phys.org / Swiss glaciers have exhausted their snow reserves
From June 29 onward, Switzerland's glaciers will have exhausted their snow reserves. Every liter of meltwater now causes them to lose mass—this is Glacier Loss Day. Between the extreme years of 2003 and 2022 alone, 200 square ...
Medical Xpress / Intracellular mechanisms promote tumor survival during hypoxia
Northwestern Medicine scientists have, for the first time, described the underlying mechanisms that regulate how cells rapidly change gene expression in response to hypoxia, a key feature of many treatment-resistant tumors, ...
Phys.org / Thirsty desert lizards inspire a new water-harvesting system
When the desert horned lizard (Phrynosoma platyrhinos) is thirsty, it cannot just lap up water or scoop it up like a bird because it lives in environments where water is extremely scarce. Typically, it's found in damp soil ...
Phys.org / Beetle-like borings in 70-million-year-old titanosaur fossils reshape Lo Hueco fossil story
Traces or perforations caused by living organisms after an animal's death can be found on various dinosaur bone remains. These perforations, known as bioerosion structures, provide information that helps us understand relationships ...
Phys.org / Unknown 4,000-year-old stone circle in Belfast uncovered by archaeologists
Archaeologists have uncovered an unknown stone circle that dates back at least 4,000 years to the Late Neolithic or Early Bronze Age and was most likely used for ritual activities.
Phys.org / Evidence identifies ancient Aboriginal mining in the Riverland
Flinders University researchers, in partnership with the River Murray and Mallee Aboriginal Corporation, have found evidence that points to 7,000 years of Aboriginal mining of stone at Sugarloaf Hill in South Australia's ...
Phys.org / Clean crystal surface lets single molecules hit ultimate quantum limit
Scientists at the Max Planck Institute for the Science of Light (MPL) have developed a technique for interrogating molecules on surfaces with spectroscopic precision, thereby reaching the ultimate quantum limit for the first ...
Phys.org / Quantum waves reveal one-sided motion marking elusive critical states
Sound waves, light waves and other types of waves, generally spread freely through space and over time. In 1958, physicist Philip W. Anderson first described a phenomenon via which irregularities or other sources of disorder ...
Phys.org / When a pool or pond turns green with algae, don't reach for chemicals—nature has better solutions
When the Lincoln Memorial Reflecting Pool turned green with algae just days after a US$15 million renovation, the U.S. government scrambled for chemicals and expensive technical solutions to fix the iconic landmark.
Phys.org / Lavatory shaft reveals the cost of 17th‑century vanity in Germany
Four goose skulls were pulled from a former toilet shaft in Brandenburg, Germany, each of them riddled with strange holes. As it turns out, these holes were the telltale signs of fancy feathered crests, making them the first ...
Medical Xpress / Uneven cerebellum aging may partly explain why some older adults stay mentally sharp
Scientists may have discovered a new role for the cerebellum, the part of the brain that sits at the base of the skull. A new paper published in the journal Nature Neuroscience reports that different parts of the cerebellum ...
