Phys.org / A nanomaterial flex—MXene electrodes help OLED display technology shine, while bending and stretching
The organic light-emitting diode (OLED) technology behind flexible cell phones, curved monitors, and televisions could one day be used to make on-skin sensors that show changes in temperature, blood flow, and pressure in ...
Phys.org / Fire on ice: The Arctic's changing fire regime
The number of wildland fires burning in the Arctic is on the rise, according to NASA researchers. Moreover, these blazes are burning larger, hotter, and longer than they did in previous decades.
Phys.org / Scientists measure cellular membrane thickness inside cells for the first time
Scientists have long known that cellular membranes vary in thickness, but measuring those differences inside actual cells has been out of reach.
Phys.org / Plants use bacterial-like gene to make alkaloids, offering new route for sustainable medicines
Plants make substances called alkaloids to protect themselves, and humans have long taken advantage of these chemicals, using them in painkillers, treatments for disease and household products such as caffeine and nicotine.
Phys.org / Avocadoes may become easier to grow in India—but not if global emissions remain high
A new study suggests that with low to moderate levels of global greenhouse emissions in coming decades, more of India could become suitable for growing avocadoes. However, with high enough emissions, growing zones could shrink ...
Phys.org / A CRISPR fingerprint of pathogenic C. auris fungi for precision diagnostics
Infection with the pathogenic yeast fungus Candida auris (C. auris) can wreak havoc on the health of hospital patients and residents of nursing homes, especially those who are already weakened by other illnesses. The pathogen ...
Phys.org / Hydrogel cilia set new standard in microrobotics
Cilia are micrometer-sized biological structures that occur frequently in nature. Their characteristic high-frequency, three-dimensional beating motions (5–40 Hz) play indispensable roles inside the body.
Phys.org / Can a bat catch prey on a mirror? A bat's expert foraging skills revealed using a robot
Scientists built a robot to help explain how a tropical bat spots insects perched on leaves using echolocation, a highly sophisticated behavior that requires precise, split-second decision making on the part of the hunting ...
Phys.org / Crop droughts set to worsen—even as rainfall increases
Europe and western North America will experience more frequent and severe crop droughts as Earth warms, even in places where yearly rainfall increases.
Phys.org / Polyamines guide cellular decisions by altering the phosphoproteomic landscape, study finds
Polyamines are small molecules naturally present in all cells and are critical in guiding cellular decisions, whereas an alteration in the abundance of these metabolites is invariably observed in pathological scenarios such ...
Phys.org / Measuring movement creates a new way to map indoor air pollution
University of Birmingham scientists have developed a new way of measuring and analyzing indoor air pollution that—in initial trials—has established a clear link between office occupancy, physical activity, and air quality.
Phys.org / Enthusiasts used their home computers to search for ET—scientists are homing in on 100 signals they found
For 21 years, between 1999 and 2020, millions of people worldwide loaned UC Berkeley scientists their computers to search for signs of advanced civilizations in our galaxy.
