Phys.org / Plug-and-play single-photon source can work at room temperature
The Korea Research Institute of Standards and Science (KRISS) has developed a room-temperature single-photon source built into a compact 19-inch rack-mounted device that operates without cryogenic cooling. Designed as a plug-and-play ...
Phys.org / Could 'Trojan horse'-type microorganisms that exploit symbiotic systems be candidates for new biological pesticides?
Researchers at National Institute of Advanced Industrial Science and Technology (AIST), in collaboration with researchers from The University of Electro-Communications (UEC) and Akita Prefectural University, have discovered ...
Phys.org / Italy displays paintings from an ancient Etruscan tomb, its latest cultural acquisition
Italy on Tuesday put on display one of the best known examples of Etruscan painting, panels from a tomb that it acquired for 15 million euros ($17 million) in the Culture Ministry's buying spree of big-ticket pieces of the ...
Tech Xplore / Giving drones a sense of 'pain' could help them predict instability before it happens
Imagine you're running and you sprain your ankle. The pain makes you gingerly limp the rest of the way home. This is a great example of how nature adapts to failures in a system. The pain tells you: "If you continue running ...
Phys.org / Orbitronics clears key hurdle with direct orbital currents, boosting signals 100-fold
Researchers at Johannes Gutenberg University Mainz (JGU) are the first to directly utilize orbital currents without the need for conversion of the orbital current into a spin current.
Medical Xpress / BCG vaccine may rewire brain immunity, shift Alzheimer's markers over 12 months
New research led by Mass General Brigham investigators suggests that the Bacillus Calmette-Guérin (BCG) vaccine—which is delivered through the skin to prevent tuberculosis—may remodel the human brain's immune environment, ...
Phys.org / Earliest Americans specialized in megafauna hunting from Alaska to South America, analysis of 50 sites reveals
New research led by a University of Alaska Fairbanks archaeologist reveals that the earliest Native Americans had highly specialized diets, primarily hunting the largest animals on the landscape, and they targeted these megafauna ...
Phys.org / Unexpected pathway turns water and CO₂ into climate‑neutral methane on nickel–zirconia
Natural gas still plays an important role in many industrial sectors, but it is a climate-damaging fossil fuel. TU Wien and the University of Innsbruck have now discovered an unexpected reaction pathway that makes it possible ...
Phys.org / Purine-heavy DNA sequences protect Bacillus subtilis genes from Rho termination
In the study of bacteria, a longstanding dogma has held that two molecular machines—RNA polymerase, which leads the way in transcribing DNA into RNA, and ribosomes, which bring up the rear translating RNA into proteins—worked ...
Phys.org / Hidden role of garnet reveals how Earth's 660-km seismic boundary forms
Nearly 660 kilometers (410 miles) beneath Earth's surface lies one of the planet's most important internal boundaries. Known as the 660-km seismic discontinuity, it separates the mantle transition zone from the lower mantle ...
Tech Xplore / Blame the model, not the machine—better data helps 3D-printed metamaterials match predictions
Additive manufacturing, such as 3D printing, provides an excellent opportunity to design metamaterials: materials with an engineered structure that leads to desired properties such as, for instance, resistance to vibrations. ...
Tech Xplore / Data centers may emit 57% more CO₂ than expected in 2025, study finds
Data centers, whose expansion is being fueled dramatically by the artificial intelligence boom, have a far bigger carbon footprint than previously estimated, a study said Tuesday.
