Phys.org / Catching light in air: Programmable Mie voids boost light matter interaction
Atomically thin semiconductors such as tungsten disulfide (WS2) are promising materials for future photonic technologies. Despite being only a single layer of atoms thick, they host tightly bound excitons—pairs of electrons ...
Phys.org / Tech upgrade reveals even finer transcription detail inside cells
In 2021, a technology developed at the University of Michigan, called Seq-Scope, revolutionized the ability to map gene activity within intact tissue at microscopic resolution, enabling researchers to measure all expressed ...
Phys.org / Scared of spiders? The real horror story is a world without them
Members of the arachnid class—think spiders, scorpions and harvestmen (daddy long legs)—are often the targets of revulsion, disgust and fear. Yet, they are crucial for ecosystems to thrive. Given the crash in worldwide ...
Dialog / Built to withstand, or built to worry? Housing and disaster risk perception
I have always been interested in how people make decisions under uncertainty—especially decisions about safety. But it was not until I began studying housing conditions and disaster risk that I realized how deeply our built ...
Phys.org / How flatworms keep their regeneration powers on track
Scientists have discovered a key biological safeguard that helps one of nature's most impressive regenerators, the planarian flatworm, correctly rebuild its organs. The new research, published in Nature Communications, illuminates ...
Phys.org / Antarctica has lost 10 times the size of Greater Los Angeles in ice over 30 years, satellite data reveal
A comprehensive 30-year study led by University of California, Irvine glaciologists has produced a circumpolar ice grounding line migration map of Antarctica. An amalgamation of three decades of satellite data compiled and ...
Phys.org / Ultrasound-activated 'nanoagents' kill superbugs hiding in biofilms
Scientists have designed nanoagents that act like smart drug-delivery capsules—carrying an antibiotic deep into bacterial infection sites and releasing it only when activated by gentle ultrasound. Delivering antibiotics ...
Phys.org / MeerKAT discovers record-breaking cosmic laser halfway across the universe
Astronomers using the MeerKAT radio telescope in South Africa have discovered the most distant hydroxyl megamaser ever detected. It is located in a violently merging galaxy more than 8 billion light-years away, opening a ...
Phys.org / A crystal that 'comes alive': Heat-driven bubbles push it forward while it changes fluorescence color
In a study published in Angewandte Chemie International Edition, researchers from National Taiwan University report that a seemingly solid, nonporous organic crystal can undergo dramatic structural and mechanical transformations ...
Phys.org / Smart fluorescent molecules provide cheaper path to sharper microscopy images
Multiphoton microscopy is used in biomedical research to study cells and tissues. Today, so-called two-photon microscopy is used to study processes within cells, but the technique has limitations in terms of image resolution. ...
Phys.org / New 2D membrane reactor improves photocatalytic synthesis
Chinese researchers have developed a photocatalytic membrane reactor that dramatically improves the synthesis of imines—a class of compounds essential to the production of pharmaceuticals, agrochemicals, and advanced synthetic ...
Phys.org / Survival training in a safe space—how staged risk helps young predators learn dangerous prey
Adaptation is essential for survival. Across species, it occurs over many generations through evolution and natural selection. Individual animals, however, can also adapt within their own lifetimes—through learning. For ...
