Phys.org / Scourge of satellites lighting up the sky could be mitigated with help of ultra-black coating
Astrophysicists working to tackle the growing impact of satellite constellations have pioneered a new ultra-black coating as one possible way to mitigate the problem.
Phys.org / Could 'Trojan horse'-type microorganisms that exploit symbiotic systems be candidates for new biological pesticides?
Researchers at National Institute of Advanced Industrial Science and Technology (AIST), in collaboration with researchers from The University of Electro-Communications (UEC) and Akita Prefectural University, have discovered ...
Phys.org / Orbitronics clears key hurdle with direct orbital currents, boosting signals 100-fold
Researchers at Johannes Gutenberg University Mainz (JGU) are the first to directly utilize orbital currents without the need for conversion of the orbital current into a spin current.
Phys.org / Quiet outings linked to more frequent dangerous wildlife encounters
The more people expand into previously natural areas, the more wildlife and humans step on each other's toes, leading to more interactions that may result in conflict. This includes national parks, where people flock to recuperate ...
Phys.org / Purine-heavy DNA sequences protect Bacillus subtilis genes from Rho termination
In the study of bacteria, a longstanding dogma has held that two molecular machines—RNA polymerase, which leads the way in transcribing DNA into RNA, and ribosomes, which bring up the rear translating RNA into proteins—worked ...
Phys.org / Hidden role of garnet reveals how Earth's 660-km seismic boundary forms
Nearly 660 kilometers (410 miles) beneath Earth's surface lies one of the planet's most important internal boundaries. Known as the 660-km seismic discontinuity, it separates the mantle transition zone from the lower mantle ...
Phys.org / Diffractive networks enable optical information transfer through random and unknown diffusers
The transmission of optical information through random scattering media is a major challenge in optics, biomedical imaging, telecommunications and remote sensing. When light passes through a turbid or diffusive medium, such ...
Phys.org / Instant digital rewards may make hard thinking feel less worthwhile
Imagine opening a difficult book in a quiet room. The first page is dense. You read one paragraph, then reread it. Nothing "clicks" yet. Your brain is doing what learning often requires: spending effort before the reward ...
Phys.org / Quantum properties of multimode light observed despite extreme losses
Quantum properties of light are extremely delicate. When researchers attempt to measure them, even small losses on the way to a detector can make them invisible, limiting their use outside carefully controlled environments. ...
Phys.org / Brown leaves before fall could signal lasting heat damage, researchers warn
Due to increasing heat and drought, forests are turning brown more often before autumn, when leaf senescence normally occurs. It is often unclear whether the trees are actively shedding foliage to avoid a breakdown in water ...
Phys.org / New biosensor reveals rare lipid gathers in membrane hotspots during cell stress
Inside every cell are lipid molecules that make up cellular membranes, helping organelles communicate and respond to stress. Researchers have struggled to observe lipids in action because current detection tools lack sufficient ...
Phys.org / Prescribed burns may generate over 20% of fine particle pollution in southeastern US
Prescribed fires are vital for reducing wildfire risk and sustaining forest biodiversity. But they also contribute significantly to air pollution and smoke exposure, according to new research from the University of Georgia. ...
