Phys.org / AI uncovers hidden rules of some of nature's toughest protein bonds
Imagine tugging on a Chinese finger trap. The harder you pull, the tighter it grips. This counterintuitive behavior also exists in biology. Certain protein complexes can form catch-bonds, tightening their grip when force ...
Phys.org / Circuits invisible to the naked eye: New technique shrinks microchips beyond current size limits
Johns Hopkins researchers have discovered new materials and a new process that could advance the ever-escalating quest to make smaller, faster and affordable microchips used across modern electronics—in everything from ...
Tech Xplore / Humans sense a collaborating robot as part of their 'extended' body
Researchers from the Istituto Italiano di Tecnologia (IIT) in Genoa (Italy) and Brown University in Providence (U.S.) have discovered that people sense the hand of a humanoid robot as part of their body schema, particularly ...
Phys.org / Newly dated 85-million-year-old dinosaur eggs could improve understanding of Cretaceous climate
In the Cretaceous period, Earth was plagued by widespread volcanic activity, oceanic oxygen depletion events, and mass extinctions. Fossils from that era remain and continue to give scientists clues as to what the climate ...
Phys.org / Nano-switch achieves first directed, gated flow of excitons
A new nanostructure acts like a wire and switch that can, for the first time, control and direct the flow of quantum quasiparticles called excitons at room temperature.
Phys.org / New dinosaur from Wales identified in museum drawer
Paleontologists at the University of Bristol have officially identified a new species of dinosaur from Triassic fossil beds in South Wales, near Penarth—more than 125 years after the specimen was initially reported.
Phys.org / Southeast Pacific sediment cores are an 8-million-year-old climate archive of temperature effects on the ocean
Under the lead of the Leibniz Institute for Baltic Sea Research Warnemünde (IOW), a sediment core from the Southeast Pacific was examined that reflects the last 8 million years of Earth's history.
Phys.org / Volcanic emissions of reactive sulfur gases may have shaped early climate of Mars, making it more hospitable to life
While the early climate of Mars remains an open question, a new study suggests that its atmosphere may have been hospitable to life due to volcanic activity that emitted sulfur gases that contributed to a greenhouse warming ...
Phys.org / How interstellar objects similar to 3I/ATLAS could jumpstart planet formation around infant stars
Interstellar objects like 3I/ATLAS that have been captured in planet-forming disks around young stars could become the seeds of giant planets, bypassing a hurdle that theoretical models have previously been unable to explain.
Phys.org / The Hofstadter butterfly: Twisted bilayer graphene reveals two distinct strongly interacting topological phases
Magic-angle twisted bilayer graphene (MATBG) is a material created by stacking two sheets of graphene onto each other, with a small twist angle of about 1.1°. At this "magic angle," electrons move very slowly, which can ...
Phys.org / eDNA alone may mislead tracking of marine species' shifting ranges, study finds
Traces of DNA in the environment can tell us how species' ranges are changing as a result of increasing sea temperatures.
Phys.org / Archaeologists uncover rare beetle ornament in ancient Hallstatt cremation burial
In a recent study, Dr. Agata Hałuszko and colleagues discovered an ornament made from beetles in a cremation grave in Domasław, Poland. The work is published in the journal Antiquity.
