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 / 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 / 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 / Antarctica's brief rebound was caused by climate variability, not a 'new normal'
Between 2021 and 2023, Antarctica appeared to be growing. Heavy snowfall fueled by wetter weather caused parts of the continent to gain mass, leading some to question whether climate change is really causing the ice to melt. ...
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 / A 100-year-old mystery in the cat kidney may be linked to scent communication
Many animals obtain information about others from scent marks left in the environment, including urine. Because these marks remain after the sender has left, they allow animals to communicate across space and time. But odor ...
Phys.org / Fastest known Milky Way star offers new test of supermassive black hole's spin
Astronomers have discovered the fastest known star in our galaxy, the Milky Way, orbiting the black hole at its center. The star, named S301, was detected with the European Southern Observatory's Very Large Telescope Interferometer ...
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 / AI screens 100,000+ membrane combinations, predicting carbon capture performance within seconds
Reducing carbon dioxide emissions from industrial processes and energy production remains one of the major technological challenges in addressing climate change. Membrane-based gas separation offers an energy-efficient alternative ...
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 / Beijing's isoprene-emitting trees highlight ozone risks in greener, hotter cities
Amid current heat waves, urban greening is once again moving to the center of public debate. Greener cities are generally expected to have cleaner air because trees capture airborne particles, absorb gaseous pollutants and ...
