Phys.org / World's oldest rock art holds clues to early human migration to Australia
A hand stencil on the wall of a cave in Indonesia has become the oldest known rock art in the world, exceeding the archaeologists' previous discovery in the same region by 15,000 years or more.
Phys.org / Stingrays inspire smarter ocean robots: The physics of fin motion
Using robotic fins, researchers at the University of California, Riverside have learned how stingrays are able to swim with impressive control. These insights could help underwater vehicles avoid disastrous ground collisions.
Tech Xplore / New heat-shrinking method integrates electronic circuits on irregular shapes
Most electronics are built on flat, stiff boards, which makes it incredibly difficult to fit them onto curved and irregular shapes we find in the real world, such as human limbs or curved aircraft wings. While flexible electronics ...
Phys.org / Resurrected ancient enzyme offers new window into early Earth and the search for life beyond it
By resurrecting a 3.2-billion-year-old enzyme and studying it inside living microbes, researchers at the University of Wisconsin–Madison have created a new way to improve our understanding of the origins of life on Earth ...
Phys.org / Entangled atomic clouds enable more precise quantum measurements
Researchers at the University of Basel and the Laboratoire Kastler Brossel have demonstrated how quantum mechanical entanglement can be used to measure several physical parameters simultaneously with greater precision.
Phys.org / Study reveals why light-driven chemical reactions often lose energy before bond-breaking
Florida State University researchers have discovered a pathway within a certain type of molecule that limits chemical reactions by redirecting light energy. The study could enable development of more efficient reactions for ...
Phys.org / Arctic cloud and ice formation affected by Russian river runoff as region studied for first time
Organic matter carried in rivers to the Russian part of the Arctic Ocean may be creating more clouds and keeping the region cooler, a new study has found.
Phys.org / Space station crew credits ultrasound machine for handling in-orbit health crisis
The astronauts evacuated last week from the International Space Station say a portable ultrasound machine came in "super handy" during the medical crisis.
Phys.org / Nash equilibria: The hidden math behind predator–prey behaviors
Animal survival depends on effective attack and defense strategies, yet how these behaviors arise remains unclear. Addressing this question, a recent study shows that predator and prey behaviors emerge naturally as stable ...
Phys.org / Single enzyme streamlines production of all four RNA building blocks
A single enzyme that can generate all four nucleoside triphosphates, the building blocks of ribonucleic acid (RNA), has been identified by researchers at the Institute of Science Tokyo. The study was published online in the ...
Phys.org / AI model that found 370 exoplanets now digs into TESS data
Scientists have discovered over 6,000 planets that orbit stars other than our sun, known as exoplanets. More than half of these planets were discovered thanks to data from NASA's retired Kepler mission and NASA's current ...
Phys.org / Copper-carrying compound targets and kills MRSA bacteria by mimicking iron
A research team at the University of Arizona College of Medicine–Tucson is developing a drug that works in combination with copper to kill bacteria, including those that cause MRSA, a type of staph infection that is resistant ...
