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 ...
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 / 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 / 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.
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 / Clocks created from random events can probe 'quantumness' of universe
A newly discovered set of mathematical equations describes how to turn any sequence of random events into a clock, scientists at King's College London reveal. The paper is published in the journal Physical Review X.
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.
Medical Xpress / Rapamycin linked to DNA damage resilience in aging human immune cells
University of Oxford-led research finds low-dose rapamycin functions as a genomic protector in aging human immune cells, lowering DNA damage.
Tech Xplore / OpenAI reaches new agreement with Microsoft to change its corporate structure
OpenAI has reached a new tentative agreement with Microsoft and said its nonprofit, which technically controls its business, will now be given a $100 billion equity stake in its for-profit corporation.
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 / Seaweed cells could give solar panels a boost
Seaweed growing along the world's coastlines could help to inspire new materials. Millions of years of evolution have shaped how seaweeds control light and color, which could offer new approaches for designers to explore.
Tech Xplore / US electric grids under pressure from energy-hungry data centers are changing strategy
With the explosive growth of Big Tech's data centers threatening to overload U.S. electricity grids, policymakers are taking a hard look at a tough-love solution: bumping the energy-hungry data centers off grids during power ...
