Symbiotic and pathogenic fungi may use similar molecular tools to manipulate plants      (via sciencedaily.com)     Original source 

Symbiotic and pathogenic fungi that interact with plants are distantly related and don't share many genetic similarities. Comparing plant pathogenic fungi and plant symbiotic fungi, scientists at the Sainsbury Laboratory Cambridge University (SLCU) have discovered that these remote relatives are using a similar group of proteins to manipulate and live within plants.

The 'breath' between atoms -- a new building block for quantum technology      (via sciencedaily.com)     Original source 

Researchers have discovered they can detect atomic 'breathing,' or the mechanical vibration between two layers of atoms, by observing the type of light those atoms emitted when stimulated by a laser. The sound of this atomic 'breath' could help researchers encode and transmit quantum information.

Thermal energy stored by land masses has increased significantly      (via sciencedaily.com)     Original source 

There are many effects of climate change. Perhaps the most broadly known is global warming, which is caused by heat building up in various parts of the Earth system, such as the atmosphere, the ocean, the cryosphere and the land. 89 percent of this excess heat is stored in the oceans, with the rest in ice and glaciers, the atmosphere and land masses (including inland water bodies). An international research team has now studied the quantity of heat stored on land, showing the distribution of land heat among the continental ground, permafrost soils, and inland water bodies. The calculations show that more than 20 times as much heat has been stored there since the 1960s, with the largest increase being in the ground.

A nanocrystal shines on and off indefinitely      (via sciencedaily.com)     Original source 

Optical probes have led to numerous breakthroughs in applications like optical memory, nanopatterning, and bioimaging, but existing options have limited lifespans and will eventually 'photobleach.' New work demonstrates a promising, longer-lasting alternative: ultra-photostable avalanching nanoparticles that can turn on and off indefinitely in response to near-infrared light from simple lasers.

Chemical and environmental engineering scientists have identified two species of bacteria found in soil that break down a class of stubborn 'forever chemicals'-- per- and poly-fluoroalkyl substances, or PFAS, that have contaminated groundwater below industrial and military sites throughout the nation. The discovery gives hope for low-cost biological cleanup of these pollutants.

Color-changing material shows when medications get too warm      (via sciencedaily.com)     Original source 

Some foods and medicines, such as many COVID-19 vaccines, must be kept cold. As a step toward a robust, stable technique that could indicate when these products exceed safe limits, researchers report a class of brilliantly colored microcrystals in materials that become colorless over a wide range of temperatures and response times. As a proof of concept, the team packaged the color-changing materials into a vial lid and QR code.

Hidden in plain sight: Windshield washer fluid is an unexpected emission source      (via sciencedaily.com)     Original source 

Exhaust fumes probably come to mind when considering vehicle emissions, but they aren't the only source of pollutants released by a daily commute. Researchers report that alcohols in windshield washer fluid account for a larger fraction of real-world vehicle emissions than previous estimates have suggested. Notably, the levels of these non-fuel-derived gases will likely remain unchanged, even as more drivers transition from gas-powered to electric vehicles.

To overcome global energy challenges and fight the looming environmental crisis, researchers around the world investigate new materials for converting sunlight into electricity. Some of the most promising candidates for high-efficiency low-cost solar cell applications are based on lead halide perovskite (LHP) semiconductors. Despite record-breaking solar cell prototypes, the microscopic origin of the surprisingly excellent optoelectronic performance of this material class is still not completely understood. Now, an international team of physicists and chemists has demonstrated laser-driven control of fundamental motions of the LHP atomic lattice.
