Detecting the impact of drought on plants with user-friendly and inexpensive techniques      (via sciencedaily.com) 

Climate change is aggravating the impact of droughts -- one of the factors that only affect plant physiology -- on all plant ecosystems worldwide. Although new tools have been developed to detect and assess drought stress in plants -- transcriptomic or metabolomic technologies, etc. -- they are still difficult to apply in natural ecosystems, especially in remote areas and developing countries.

Feedback loops make climate action even more urgent, scientists say      (via sciencedaily.com) 

Researchers have identified 26 global warming accelerators known as amplifying feedback loops that the researchers say aren't being properly included in climate models. They note that the findings add urgency to the need to respond to the climate crisis and provide a roadmap for policymakers aiming to avert the most severe consequences of a warming planet.

Scientists engineer a 'self-charging' electrostatic face mask for prolonged air filtration, reducing the environmental burden      (via sciencedaily.com) 

Researchers have engineered an electrostatic face mask that can 'self-charge' through the user's breathing and continuously replenish its electrostatic charge as the user wears and breathes through the mask. This significantly increase the filtering performance in prolonged use of the mask for up to 60 hours, compared to four hours for a conventional surgical mask. This also benefits the environment.

Keeping drivers safe with a road that can melt snow, ice on its own      (via sciencedaily.com) 

Slipping and sliding on snowy or icy roads is dangerous. Salt and sand help melt ice or provide traction, but excessive use is bad for the environment. And sometimes, a surprise storm can blow through before these materials can be applied. Now, researchers ave filled microcapsules with a chloride-free salt mixture that's added into asphalt before roads are paved, providing long-term snow melting capabilities in a real-world test.

Atom-thin walls could smash size, memory barriers in next-gen devices      (via sciencedaily.com) 

For all of the still-indistinguishable-from-magic wizardry packed into the three pounds of the adult human brain, it obeys the same rule as the other living tissue it controls: Oxygen is a must. So it was with a touch of irony that a scientists offered his explanation for a technological wonder -- movable, data-covered walls mere atoms wide -- that may eventually help computers behave more like a brain. 'There was unambiguous evidence that oxygen vacancies are responsible for this,' Tsymbal said.

Fighting climate change: Ruthenium complexes for carbon dioxide reduction to valuable chemicals      (via sciencedaily.com) 

Excessive use of fossil fuels leads to undesired carbon dioxide (CO2) generation, accelerating climate change. One way to tackle this is by converting CO2 into value-added chemicals. On this front, researchers have recently utilized a novel redox couple, for the purpose.

Endangered Bahamas bird may be lost from island following hurricane      (via sciencedaily.com) 

The endangered Bahama Warbler may be surviving on just one island following Hurricane Dorian's devastation in 2019, according to researchers. A new study shows the bird's distribution and ecology on Grand Bahama before the hurricane struck. But the team says that the warbler may now only survive on neighboring Abaco island, after hurricane Dorian destroyed the bird's forest habitat on Grand Bahama. The research comes from the same team that found what is thought to have been the last living Bahama Nuthatch, previously thought to have been extinct.

Severe weather straining electrical grids: New research mitigates demand surges, increasing grid reliability and reducing costs      (via sciencedaily.com) 

Concerns are mounting among policymakers and utility companies amid the impact of severe weather on the nation's electrical grids. In recent months, electrical grids in Texas have been tested to the point of near failure. So it seems like perfect timing that new research identifies a new method that provides the best way to utilize 'direct load control contracts' to mitigate electricity demand surges, increase grid reliability and reduce electricity cost. All of this right down to the individual household.

More frequent atmospheric rivers hinder seasonal recovery of Arctic sea ice      (via sciencedaily.com) 

The Arctic is rapidly losing sea ice, even during winter months when temperatures are below freezing and ice should be recovering from the summer melt. A new study found powerful storms called atmospheric rivers are increasingly reaching the Arctic in winter, slowing sea ice recovery and accounting for a third of all winter sea ice decline, according to a team led by Penn State scientists.
