Phys.org / Oldest known sewn hide and other artifacts from Oregon caves shed light on early clothing in harsh climates
In 1958, an amateur archaeologist named John Cowles excavated the Cougar Mountain Cave in Oregon and retained many of the artifacts found there. Upon his death in the 1980s, these items were transferred to the Favell Museum ...
Phys.org / Subaru observations suggest an intrinsic gap in NGC 5466's tidal stream
Astronomers from the National Astronomical Observatory of Japan (NAOJ) and elsewhere have used the Subaru Telescope to perform deep imaging observations of a distant globular cluster known as NGC 5466. The observational campaign ...
Phys.org / Scientists say genetic analysis could greatly speed restoration of iconic American chestnut
Billions of American chestnut trees once covered the eastern United States. They soared in height, producing so many nuts that sellers moved them by train car. Every Christmas, they're called to mind by the holiday lyric ...
Phys.org / It takes three types of thinking to be smart
Do you know what it means to be smart? It's a more complicated question than it may seem. There are several ways to think about intelligence—as the well-known "book-vs.-street smart" binary illustrates. By most people's ...
Phys.org / Nanolaser on a chip could cut computer energy use in half
Researchers at DTU have developed a nanolaser that could be the key to much faster and much more energy-efficient computers, phones, and data centers. The technology offers the prospect of thousands of the new lasers being ...
Phys.org / Fossil discovery suggests giant pythons once roamed Taiwan
Pythons are a common sight across much of Asia, especially in the tropical jungles and wetlands of countries like Vietnam, Thailand and Indonesia. But one curious exception has been the main island of Taiwan, where there ...
Phys.org / Where'd you get that frog? Study traces illicit online amphibian trade
Keeping amphibians as pets offers hobbyists an opportunity to connect with the non-human world, often increasing interest in conserving animals in the wild. But there's a dark side to the amphibian trade, according to a study ...
Phys.org / Machine learning reveals hidden landscape of robust information storage
In a new study published in Physical Review Letters, researchers used machine learning to discover multiple new classes of two-dimensional memories, systems that can reliably store information despite constant environmental ...
Phys.org / Physicists develop new protocol for building photonic graph states
Physicists have long recognized the value of photonic graph states in quantum information processing. However, the difficulty of making these graph states has left this value largely untapped. In a step forward for the field, ...
Phys.org / 600 Florida green sea turtles stranded amid cold plunge
Cold air and frigid waters have caused more than 600 young green sea turtles to wash ashore on Florida's beaches this month—and more are turning up every day.
Phys.org / Building blocks of life discovered in Bennu asteroid rewrite origin story
Amino acids, the building blocks necessary for life, were previously found in samples of 4.6-billion-year-old rocks from an asteroid called Bennu, delivered to Earth in 2023 by NASA's OSIRIS-REx mission. How those amino acids—the ...
Phys.org / Oldest known reptile skin impressions dated to 298 million years found in Germany
An international research team led by Dr. Lorenzo Marchetti from the Museum für Naturkunde Berlin has described the oldest known impressions of reptile skin from the Thuringian Forest in central Germany. Particularly remarkable ...
