Phys.org / Volcano myths unravel, from 'smoke' plumes to Yellowstone catastrophe claims
Volcanoes emit smoke. Beneath a volcano lies a huge chamber filled with liquid magma. A series of earthquakes means an eruption is imminent. And if a "supervolcano" like Yellowstone were to awaken, a global catastrophe would ...
Phys.org / 3D-printed ceramic waveguide lasers could surpass the power of glass fiber lasers by 10 times
At the bottom of the ocean, optical fibers transmit telecommunications and internet data around the world. Waveguides make that feat possible by channeling and amplifying the light—and therefore the data within—over enormous ...
Phys.org / Oases in the desert of Arabia created 'brands' in the Bronze Age
Did brands exist before modern society, in noncapitalist economies? An international team led by Marta Luciani of the University of Vienna has made unexpected discoveries about Bronze Age trade: Yes, brands did indeed exist ...
Phys.org / Search in strange quark sector reveals new particle possibilities
Despite science's best efforts to classify the vast menagerie of subatomic particles discovered over the past few decades, some exotic varieties defy explanation. Now, nuclear physicists at the U.S. Department of Energy's ...
Phys.org / Reusing liquid pickle waste to produce omega-3 fatty acids
Docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are omega-3 fatty acids known to have beneficial effects and are popular as functional foods and dietary supplements. They are polyunsaturated fatty acids (PUFAs); ...
Phys.org / Evolutionary process behind live birth in lizards uncovered
Scientists studying one of nature's greatest reproductive innovations have discovered how some lizards evolved from laying eggs to giving birth to live young. The new research is the first to reveal the evolutionary process ...
Phys.org / A viral 'loose cannon' enzyme helps phages shut down bacterial defenses
As antimicrobial resistance grows around the world, novel therapies to counter it become increasingly important. Phages—viruses that infect bacteria—are an exciting avenue of research in this regard, providing a means to ...
Phys.org / Supramolecular nanofibers paired with nanohole substrate improve exciton transport in organic solid
Self-assembling, anthracene-based supramolecular nanofibers can enable excitons to migrate hundreds of nanometers, according to a new experimental finding by researchers at Science Tokyo. Coupling these nanofibers with a ...
Phys.org / New lipid nanoparticle delivers capped circular RNA for longer-lasting gene expression
Researchers at Nagoya University in Japan in collaboration with FUJIFILM have developed a novel way of delivering circular RNA (cirRNA) into cells, paving the way for longer-lasting mRNA-based therapeutics including cancer ...
Phys.org / Were Denisovans tall compared to other ancient humans? We should be skeptical
Take a walk in London's Trafalgar Square this summer, and people of all body sizes—some tall, some short—will be wilting in the heat: a real mix of sizes.
Phys.org / 'Disarming' discovery could help scientists fight deadly fungal infections
Researchers from Monash University, in collaboration with the University of Warwick, have discovered how the bacterial antibiotic "gladiolin" can disarm Candida albicans, one of the leading causes of life-threatening fungal ...
Phys.org / Too much RNA can starve cells of energy, study finds
A new study from researchers at the Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS) has uncovered a previously unknown consequence of viral infection: Too much RNA inside a cell can disrupt its ability ...
