Phys.org / Multiwavelength monitoring reveals distant blazar OP 313's behavior
An international team of astronomers has analyzed the data from long-term multiwavelength monitoring of a distant blazar known as OP 313. Results of the new study, published January 18 on the arXiv preprint server, shed more ...
Phys.org / Webb pushes boundaries of observable universe closer to Big Bang
The NASA/ESA/CSA James Webb Space Telescope has topped itself once again, delivering on its promise to push the boundaries of the observable universe closer to cosmic dawn with the confirmation of a bright galaxy that existed ...
Phys.org / Just the smell of lynx can reduce deer browsing damage in recovering forests
New research shows that the mere smell of predators is enough to change deer behavior and limit browsing damage to tree saplings. The findings, published in the Journal of Applied Ecology, offer a potential tool for forest ...
Phys.org / Asteroid that wiped out dinosaurs had limited impact on sharks and rays, study shows
A new study using advanced artificial intelligence (AI) has revealed that the asteroid strike that wiped out the dinosaurs 66 million years ago caused only a modest decline in shark and ray species. The findings, published ...
Phys.org / A possible ice-cold Earth discovered in the archives of the retired Kepler Space Telescope
Scientists continue to mine data gathered by NASA's Kepler Space Telescope, retired in 2018, and continue to turn up surprises. A new paper reveals the latest: a possible rocky planet slightly larger than Earth, orbiting ...
Phys.org / Beyond polymers: New state-of-the-art 3D micro and nanofabrication technique overcomes material limitations
Building things so small that they are smaller than the width of a human hair was previously achieved by using a method called two-photon polymerization, also known as 2PP—today's state-of-the-art in 3D micro- and nanofabrication. ...
Phys.org / Essential oils may provide a natural remedy for antibiotic resistance
Thyme, rosemary, and lavender have long been associated with natural medicine. Today, however, these aromatic plants are increasingly being studied by researchers. "In an era of ever-increasing microbial resistance to antibiotics, ...
Phys.org / A protein thought to play a supporting role in DNA replication actually facilitates the whole process
Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its code and build new strands. ...
Phys.org / Chip-sized optical amplifier can intensify light 100-fold with minimal energy
Light does a lot of work in the modern world, enabling all types of information technology, from TVs to satellites to fiber-optic cables that carry the internet across oceans. Stanford physicists recently found a way to make ...
Phys.org / Great white sharks grow a whole new kind of tooth for slicing bone as they age
A great white shark is a masterwork of evolutionary engineering. These beautiful predators glide effortlessly through the water, each slow, deliberate sweep of the powerful tail driving a body specialized for stealth, speed ...
Phys.org / Massive runaway stars in the Milky Way: Observational study explores origins and ejection process
Researchers from the Institute of Cosmos Sciences of the University of Barcelona (ICCUB) and the Institute of Space Studies of Catalonia (IEEC), in collaboration with the Institute of Astrophysics of the Canary Islands (IAC), ...
Phys.org / Small-scale farmers produce more of the rich world's food than previously thought
Who grows our food? This seemingly simple question is getting harder to answer in a world where our food crosses borders to get to our plate.
