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 / 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 / Bacterial 'brains' operate on the brink of order and disorder
The sensory proteins that control the motion of bacteria constantly fluctuate. AMOLF researchers, together with international collaborators from ETH Zurich and University of Utah, found out that these proteins can jointly ...
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 / 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 / Cleaner ship fuel changed clouds, but not their climate balance
To reduce air pollution associated with ocean transport, the International Maritime Organization tightened restrictions on sulfur content in ship fuel, resulting in an 80% reduction in emissions by 2020. That shift created ...
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 / Svalbard polar bears show improved fat reserves despite sea ice loss
The body conditions of polar bear (Ursus maritimus) populations around the Norwegian island of Svalbard have improved despite sea ice losses, according to new findings. The findings differ from previously published observations ...
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 / 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 ...
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 / 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 ...
