Phys.org / Mysterious 'red dots' in early universe may be 'black hole star' atmospheres
Tiny red objects spotted by NASA's James Webb Space Telescope (JWST) are offering scientists new insights into the origins of galaxies in the universe—and may represent an entirely new class of celestial object: a black ...
Phys.org / An exploding black hole could reveal the foundations of the universe
Physicists have long believed that black holes explode at the end of their lives, and that such explosions happen—at most—only once every 100,000 years. But new research published in Physical Review Letters by physicists ...
Phys.org / Physicists devise an idea for lasers that shoot beams of neutrinos
At any given moment, trillions of particles called neutrinos are streaming through our bodies and every material in our surroundings, without noticeable effect. Smaller than electrons and lighter than protons, these ghostly ...
Phys.org / Atomic-level engineering enables new alloys that won't break in extreme cold
Navigating the extreme cold of deep space or handling super-chilled liquid fuels here on Earth requires materials that won't break. Most metals become brittle and fracture at such low temperatures. However, new research is ...
Phys.org / 'Potential biosignatures' found in ancient Mars lake
A new study suggests a habitable past and signs of ancient microbial processes on Mars. Led by NASA and featuring key analysis from Imperial College London, the work has uncovered a range of minerals and organic matter in ...
Phys.org / Is space worth the cost? Accounting experts say its value can't be found in spreadsheets
Since the early days of human space exploration, the endeavor has been haunted by a very good question: why spend so much on space when there are so many urgent problems here on Earth?
Phys.org / New metrics indicate habitat fragmentation has increased in over half the world's forests over the last 20 years
Deforestation is a well-known issue affecting biodiversity and carbon storage, but the fragmentation of forests is also a driving factor in the reduction of the world's biodiversity and carbon-storing abilities.
Phys.org / A pollution paradox: Wildfires in the western United States may improve air quality
Climate change is driving more frequent and more intense wildfires around the world, including in the United States. These huge blazes cause a range of problems that affect health, the environment, property and the economy. ...
Phys.org / Hawking and Kerr black hole theories confirmed by gravitational wave
Scientists have confirmed two long-standing theories relating to black holes—thanks to the detection of the most clearly recorded gravitational wave signal to date.
Tech Xplore / EU to fast-track review of 2035 combustion-engine ban
The EU pledged Friday to fast-track a review of its plans to end combustion-engine vehicle sales by 2035, after pressure from Europe's embattled carmakers.
Medical Xpress / Phase I trial finds topical PXS-6302 generally well tolerated in established skin scars
University of Western Australia's Burn Injury Research Unit with the Fiona Wood Foundation reports that topical pan-lysyl oxidase inhibition with PXS-6302 was generally well tolerated over three months and altered extracellular ...
Phys.org / Pro-climate sentiments are more common than you think
While Sandra Geiger was at a conference as a doctoral student, the keynote speaker asked the audience a question: What percentage of people do you think are skeptical of climate change? Some said 30%. Others 50%. But the ...
