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 / 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 / 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 / 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 / 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 / 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 ...
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 ...
Phys.org / Peru's highest mountain confirms tropics were a major methane source before the industrial era
A new analysis of ice cores collected from the Andes in Peru has produced the first global record of historical tropical methane, filling a critical gap in our understanding of the origins of Earth's greenhouse gases.
Phys.org / Foreign tariffs made U.S. whiskey cheaper... depending on where you live
A new study finds that one side effect of Trump-era trade wars has been cheaper whiskey in much of the United States. But if you live in whiskey hubs Kentucky or Tennessee, your prices actually went up.
Phys.org / Archaeologists unveil skeletal remains believed to be ritual offering in Peru
Archaeologists on Tuesday unveiled the skeletal remains of an adult they believe was buried as an offering near the base of Huaca Pucllana, an ancient adobe pyramid in Peru's capital of Lima.
Phys.org / Neutron capture experiment sheds light on ancient stardust
Niobium-94, an isotope of niobium with 41 protons and 53 neutrons, is a critical crossroads in the complex nuclear processes that forge heavy elements under the intense pressures and temperatures of dying stars. In an article ...
