Phys.org / Webb and Hubble reveal the history of a relic of Milky Way's formation
Researchers using two of humanity's most powerful observatories—NASA's James Webb and Hubble Space Telescopes—have definitively shown that Terzan 5 is not a globular star cluster, as it was once classified, offering new insight ...
Phys.org / Santa Cruz trail study reveals how mountain lions and outdoor recreation can safely share spaces
California's iconic Santa Cruz Mountains are an outdoor recreation wonderland. With a world-class network of hiking, mountain biking and equestrian trails, they draw millions of visitors each year from neighboring Santa Cruz, ...
Phys.org / Physicists identify upper limit to resistivity in a pure metal
Experimental atomic physicists have discovered there is a maximum amount of electrical resistance, or resistivity, that can result from collisions between electrons.
Phys.org / Intensive nickel mining has transformed microbial biodiversity of Thio Lagoon in New Caledonia
A study carried out by scientists from Ifremer, IRD, the universities of Western Brittany (UBO) and Bordeaux, CNRS, and the University of Tartu (Estonia) reveals the impact of nickel mining on the coastal ecosystems of New ...
Phys.org / New method enables accurate sequencing of short peptides hidden in food and human body
Our food and our bodies are full of tiny protein fragments called peptides. These small chains of amino acids act as biological messengers, influencing processes ranging from sensory perception to physiological functions.
Dialog / Slaughter in the water: Can the Ramsar Convention protect African waterbirds?
The Ramsar Convention is the world's longest-standing international treaty for wetland and waterbird protection. Signed in Ramsar, Iran, in 1971, the Convention on Wetlands of International Importance Especially as Waterfowl ...
Phys.org / Cockatoos learn when touchscreen rewards 'die,' then apply rule to new contexts
For humans, death is surrounded by culture, emotion, ritual and language. But the question can be framed in a much more basic way: What would an animal have to understand in order to recognize that someone has died?
Phys.org / Why one famous predator shrank two ways: Fossils reveal distinct growth strategies in early Permian Dimetrodon
The sail-backed predator Dimetrodon is one of the most iconic animals of the early Permian—long before dinosaurs dominated Earth. Most known species of this early relative of mammals reached large body sizes, sometimes up ...
Phys.org / A flexible graphene-based neural interface can 'speak and listen' to the brain
Neural interfaces are devices that can detect or modulate neuronal activity when placed in contact with the brain. They are already used to treat various conditions related to the nervous system. However, current technologies ...
Phys.org / RNA barcoding approach reveals previously unknown virus–host relationships
An interdisciplinary team of Rice University researchers has uncovered previously unknown relationships between bacteriophages—viruses that infect bacteria—and their bacterial hosts, offering a powerful new tool for next-generation ...
Phys.org / A new explanation for the mystery death of Botticelli's Birth of Venus model, Simonetta Vespucci
A paper on new research into the cause of death of Simonetta Vespucci, model for the world-renowned Birth of Venus by Sandro Botticelli, has been published by researchers at Queen Mary University of London, Universita Campus ...
Phys.org / Genome-wide analysis uncovers clues to Faroese ancestral history
Genome sequencing has revealed insights into how current-day residents of the Faroe Islands can trace their ancestry to a North Atlantic founder population and how evolutionary forces have shaped their genomes since. The ...
