Phys.org / Photocatalysis enables direct coupling of native sugars and N-heteroarenes
Researchers from the National University of Singapore (NUS) have developed a "capping-and-coupling" strategy to transform naturally occurring (native) sugars directly into compounds known as C-heteroaryl glycosides. This ...
Phys.org / Scientists develop high-performance Hg-based crystal for mid-far infrared birefringence
Mid- and far-infrared birefringent crystals are key functional materials for polarization control, laser technologies, and infrared photonics. However, existing materials generally suffer from limited infrared transparency, ...
Phys.org / How plants respond to changing environments for better reproductive success
Once a seed germinates, it is committed to one location. Plants are sessile—stuck where they started out—forced to cope with whatever conditions arrive next. The only way out of trouble is to rebuild themselves in place.
Phys.org / Flying gurnard grunts and flares fins to communicate, camera study confirms
Researchers have just published a study demonstrating that the flying gurnard (Dactylopterus volitans) emits sounds while simultaneously performing movements to communicate—a discovery that enriches our knowledge about ...
Phys.org / Caribbean heat waves intensify over five decades, study finds
A new study led by climatologists at the University at Albany has found that extreme heat waves across the Caribbean are becoming significantly more frequent, longer and severe. This study examined extreme summer heat waves ...
Phys.org / Collective intelligence: How to incentivize problem solving in groups
When a crowd gets something right, like guessing how many beans are in a jar, forecasting an election, or solving a difficult scientific problem, it's tempting to credit the sharpest individual in the room. But new research ...
Phys.org / Refractive-index microscope measures a sample's optical properties with pinpoint accuracy
By combining two fundamentally different microscopy techniques, researchers can now measure the optical properties of a sample with pinpoint accuracy. The original goal was to investigate biological samples on a molecular ...
Phys.org / 'Jerk' volcano early warning method uses single seismometer to detect magma movement
Forecasting volcanic eruptions in time to alert authorities and populations remains a major global challenge. In a study published in Nature Communications, researchers and engineers from the Institut de Physique du Globe ...
Phys.org / Male or female? How one frog gene 'hijacked' sex determination about 20 million years ago
Early in development, many animals pick a team—male or female—based on their genetics, and, with time, acquire the characteristics to match. New research from the Marine Biological Laboratory (MBL) explores how one species ...
Phys.org / Programmable terahertz vortices enable dual electric and magnetic skyrmion modes
Researchers have created an optical device that can generate both electric and magnetic vortex-ring-like light patterns. These structured light vortices, known as skyrmions, are highly stable and resistant to disturbances, ...
Phys.org / King's Trough: How a shifting plate boundary and hot mantle material shaped an Atlantic mega-canyon
The King's Trough Complex is a several-hundred-kilometer-long, canyon-like system of trenches on the North Atlantic seafloor. Its formation was long thought to be the result of simple stretching of the oceanic crust. An international ...
Phys.org / Crosstalk inside cells helps pathogens evade drugs, study finds
Biologists have uncovered a new mode of communication inside cells that helps bacterial pathogens learn how to evade drugs. Their findings, published in the journal Nature Communications, describe how these mechanisms drive ...
