Phys.org / Young 'sun' caught blowing bubbles by Chandra
For the first time, a much younger version of the sun has been caught red-handed blowing bubbles in the galaxy by astronomers using NASA's Chandra X-ray Observatory. The bubble—called an "astrosphere"—completely surrounds ...
Phys.org / Globe-trotting ancient 'sea-salamander' fossils rediscovered from Australia's dawn of the Age of Dinosaurs
Around 250 million years ago, what is today scorching desert in remote northwestern Australia was the shore of a shallow bay bordering a vast prehistoric ocean. Fossils recovered from this region over 60 years ago, and almost ...
Phys.org / Turning high-emissions waste into fertilizer: Catalyst boosts urea production by coupling CO₂ with nitrogen pollutants
UNSW engineers have tackled a longstanding problem at the heart of global agriculture: how to make urea for fertilizer without the intensity of emissions associated with fossil-fuel-powered factories. The solution is outlined ...
Phys.org / Scientists deliver new molecule for getting DNA into cells
Researchers from Tokyo Metropolitan University have created a new molecule which carries DNA into biological cells, to treat or vaccinate against illnesses. Many existing options rely on molecules with a strong positive charge, ...
Phys.org / Between the Pampa and Patagonia: New clues about how ancient hunter-gatherers fed themselves
An archaeological study reveals how ancient hunter-gatherer groups lived—and survived—more than a thousand years ago in the transition zone between the Pampas and Patagonia in Argentina. The research, carried out by Martínez ...
Phys.org / System isolates single extracellular vesicle surface proteins to map function
Extracellular vesicles (EVs) are tiny biological bubbles that carry nucleic acids and proteins between cells, playing an essential role in tissue repair, neuroprotection and immune health. By isolating the surface proteins ...
Phys.org / Why the planet doesn't dry out all at once: Scientists solve a global climate puzzle
Researchers at the Indian Institute of Technology Gandhinagar (IITGN), in collaboration with international partners, have shown that ocean temperature patterns help limit the global spread of droughts. Published in Communications ...
Phys.org / Alloy-engineered valleytronics: Microscopic mechanism gives scientists precise control over how excitons behave
Scientists have observed a new microscopic mechanism enabling precise control of the magneto-optical properties of excitons in alloys of two-dimensional semiconductors. This discovery opens up tangible prospects for technological ...
Phys.org / Auroras on Ganymede and Earth share striking similarities
New observations of Ganymede reveal a striking similarity between the auroras on the largest moon in the solar system and those on Earth. The international team of astrophysicists, led by researchers from the University of ...
Phys.org / Animal muscles inspire biomaterial design for agriculture, fabrics and medicine
Natural muscle fibers are made up of spring-like proteins that can contract and stretch without losing their original form, dissipate mechanical energy as heat and maintain incredible tensile strength for all sorts of physical ...
Phys.org / Tuning in to fluorescence to farm smarter: Monitoring plant light use saves indoor farm energy costs
Plant owners with a so-called green thumb often seem to have a more finely tuned sense of what their plants need than the rest of us. A new "smart lighting" system for indoor vertical farms grants this ability on a facility-wide ...
Phys.org / Ultra-efficient optical sensors can keep light circulating longer inside a microscopic chip
CU Boulder researchers have built high-performing optical microresonators, opening the door for new sensor technologies. At its simplest form, a microresonator is a tiny device that can trap light and build up its intensity. ...
