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 / 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 / How the Ampelomeryx grew: Discovering the life history of a giraffe relative that lived in Catalonia
A research team from the Institut Català de Paleontologia Miquel Crusafont (ICP-CERCA) has led the paleohistological study of Ampelomeryx ginsburgi, a giraffomorph ruminant from the Middle Miocene recovered at the Els Casots ...
Phys.org / Frozen in dry ice, hydrogen reveals a surprisingly simple way to control quantum behavior
A new study by University of Maryland chemical physicists demonstrates how to control the nuclear spin of molecular hydrogen (H2) by simply freezing it in dry ice. This new technique, published in the journal Physical Review ...
Medical Xpress / Experimental KRAS G12D drug slows cancer growth, shrinks tumors in early test
A first-in-human clinical trial led by an international team of researchers and published in the New England Journal of Medicine found that setidegrasib, an investigational targeted therapy drug designed to eliminate a key ...
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 ...
Tech Xplore / Solar photoreforming turns plastic waste into clean fuel at low temperatures
Scientists are advancing a promising solution to two of the world's biggest challenges—plastic pollution and clean energy—by transforming waste plastics into valuable fuels using sunlight.
Phys.org / Early human embryonic cells may be vulnerable to SARS-CoV-2 infection
A University of California, Riverside study reports that cells in the earliest stages of human development could be susceptible to infection by SARS-CoV-2, which causes COVID-19, offering new insight into how the virus interacts ...
Phys.org / Immigrants help address the US eldercare shortage, analysis shows
Good caregivers are often in short supply, but after the COVID-19 pandemic hit the U.S. in early 2020, staff levels at nursing homes dropped by 10%. What was a simple personnel shortage has moved closer to being a nursing-care ...
Phys.org / Room-temperature vibrations could transform how industry makes graphene
Researchers have demonstrated a new technique for creating 2D materials that runs at room temperature and increases production rates tenfold over current methods, without using toxic solvents. Scientists led by Dr. Jason ...
Phys.org / Light can now be shaped in empty space, and it could simplify sensing and boost data links
Scientists at the University of East Anglia have uncovered a hidden property of light that allows it to twist, spin and behave differently—without mirrors, materials or special lenses. In a breakthrough that could transform ...
Medical Xpress / Brazilian tree compounds block SARS-CoV-2 at multiple stages, lab tests show
A study has revealed that galloylquinic acids extracted from the leaves of Copaifera lucens Dwyer, a tree endemic to Brazil primarily found in the Atlantic Forest, have a multi-targeted effect against SARS-CoV-2, the virus ...
