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 / 'Geriatric' butterfly species lives nearly three times as long as their relatives
A tropical butterfly has evolved an ingenious anti-aging strategy by delaying the aging process, enabling it to live far longer than its closest relatives, according to a new University of Bristol-led study published in Nature ...
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 / Third time's the charm for a row of faint galaxies without dark matter
A Yale-led team of astronomers has found a third galaxy devoid of dark matter—located alongside the other two in a formation that has never been seen before. Astronomers have followed a faint, cosmic trail of gas to a third ...
Phys.org / When glaciers vanish, so does the hidden life they support
We often hear about glacier melting and predictions of what climate change could do. But very little is mentioned about the effects on ecosystems or the animals that call them home. To redress some of this imbalance, an international ...
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 / 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 / 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 / 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 / Random deformation lets glassy materials store precise mechanical memories, simulations reveal
Amorphous materials such as glass are solids whose internal structure lacks a repeating pattern. Their molecules are arranged in a random and irregular way. Surprisingly, these disordered materials can "remember" past mechanical ...
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 / Young disk around WRAY 15-1880 may contain a primitive planetary system
Italian astronomers have used the Very Large Telescope (VLT) to perform polarimetric observations of the star WRAY 15-1880 and its young circumstellar disk. Results of the new observations, presented June 10 on the arXiv ...
