Phys.org / A new 'molecular switch' for inborn immunity identified
Innate immune sensors—known as pattern recognition receptors (PRRs)—detect specific molecular components of bacterial or viral intruders. The PRRs forward the signals which results in the production of interferons, which ...
Phys.org / Overshoot reshapes climate strategies—but the path to net zero remains unchanged
Temporary overshoot of global temperature targets—particularly the 1.5°C goal of the Paris Agreement—is no longer just a modeling concept. New research, published in Nature Climate Change and led by the Euro-Mediterranean ...
Phys.org / Large area MoS₂ reduces energy loss in magnetic memory films
Scientists at the University of Manchester have discovered that placing magnetic films on atomically thin molybdenum disulfide (MoS₂) fundamentally changes how they lose energy, a finding that could bring 2D‑material ...
Phys.org / The 'Great Texas Freeze' killed thousands of purple martins: Biologists worry recovery could take decades
Thousands of birds, including beloved purple martins, died in "The Great Texas Freeze" of 2021. A study published in Nature Ecology & Evolution led by biologists at the University of Massachusetts Amherst, reveals not only ...
Phys.org / Recreating the forms and sounds of historical musical instruments
What if there were a way to create accurate replicas of ancient and historical instruments that could be played and heard?In late 2024, senior MIT postdoc Benjamin Sabatini wrote MIT Professor Eran Egozy to ask just that, ...
Phys.org / X-raying rocks reveals their carbon-storing capacity
To avoid the worst effects of climate change, many billions of metric tons of industrially generated carbon dioxide will have to be captured and stored away by the end of this century. One place to store such an enormous ...
Phys.org / Light-guided 'optovolution' evolves proteins that switch states on schedule
EPFL researchers have developed a light-based method that can produce proteins that switch states, respond to signals, and even compute, using light and the cell cycle.
Phys.org / How old is the universe? The oldest stars give us a clue
Researchers from the University of Bologna and the Leibniz Institute for Astrophysics Potsdam (AIP) along with other institutes have proposed a new way to address the Hubble tension by comparing estimates of the universe's ...
Phys.org / Toward practical laser-driven light sails using photonic crystals
Most space missions rely on chemical rockets for propulsion. Rockets must carry fuel, which increases spacecraft mass and limits their speed and travel distance. For decades, researchers have explored light sails as an alternative. ...
Phys.org / Missing technosignatures? Turbulent plasma may blur ultra-narrow signals before they leave their home star systems
A new study by researchers at the SETI Institute suggests that stellar "space weather" could make radio signals from extraterrestrial intelligence harder to detect. Stellar activity and plasma turbulence near a transmitting ...
Phys.org / Scientists create a hexagonal diamond that could be even harder than the real thing
To misquote a famous song, "Diamonds are industry's best friend." Cubic diamond is the hardest mineral on Earth and is used in everything from precision cutting tools to high-performance semiconductors as well as expensive ...
Phys.org / Neutrons reveal magnetic signatures of chiral phonons
Physicists in China have uncovered new evidence that chiral phonons and magnons can interact strongly inside magnetic crystals. Using neutron spectroscopy, a team led by Song Bao at Nanjing University mapped magnetic signatures ...
