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 / 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 / Buried in soil, a 100-million-year-old bacterial toxin could reshape pest control and antibiotic discovery
In every backyard, park, and playground on Earth, the ground is teeming with a type of bacteria called Streptomyces—one of the most abundant organisms on the planet. While these dirt-dwelling microbes are known for producing ...
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 / Standardized runoff dataset could improve forecasts of urban microplastic pollution
As rain falls, lurking within stormwater runoff are hidden microplastics, polluting the water sources they drain into. Even though microplastics originate in urban environments such as cities, existing data sets focus on ...
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 / 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 / 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 ...
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 / 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 / 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 / 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 ...
