Bacteria-coated nanofiber electrodes digest pollutants

Cornell materials scientists and bioelectrochemical engineers may have created an innovative, cost-competitive electrode material for cleaning pollutants in wastewater.

Ozone recovery may be delayed by unregulated chemicals

Recent increases in an unregulated ozone-depleting substance, could delay recovery of Antarctic ozone levels by 5–30 years, depending on emissions scenarios.

The findings, published in Nature Communications, suggest that a previously ignored chemical called dichloromethane may now be contributing to ozone depletion and should be considered to improve future ozone predictions.

NASA Looks at Rainfall from Tropical Storm Dora

Now a tropical storm, Hurricane Dora has been skirting southwestern Mexico’s coast since it formed and has transported tropical moisture onshore that has produced some heavy rain showers. The Global Precipitation Measurement mission or GPM core satellite has analyzed those rainfall rates.

Image analysis and artificial intelligence (AI) will change dairy farming

A group of researchers led by Osaka University developed an early detection method for cow lameness (hoof disease), a major disease of dairy cattle, from images of cow gait with an accuracy of 99% or higher by applying human gait analysis. This technique allows early detection of lameness from cow gait, which was previously difficult. It is hoped that a revolution in dairy farming can be achieved through detailed observation by AI-powered image analysis.

Ruthenium rules for new fuel cells

Rice University scientists have fabricated a durable catalyst for high-performance fuel cells by attaching single ruthenium atoms to graphene.

Catalysts that drive the oxygen reduction reaction that lets fuel cells turn chemical energy into electricity are usually made of platinum, which stands up to the acidic nature of the cell’s charge-carrying electrolyte. But platinum is expensive, and scientists have searched for decades for a suitable replacement.

The trouble with being a handsome bird

Male birds often use brightly coloured plumage to be attractive to females. However, such eye-catching trimmings may also attract unwanted attention from predators. Now, a new study led by Monash University has found that showy males indeed perceive themselves to be at a greater risk of predation.

Injectable Plant-based Nanoparticles Delay Tumor Progression

Researchers from Case Western Reserve University School of Medicine in collaboration with researchers from Dartmouth Geisel School of Medicine and RWTH Aachen University (Germany) have adapted virus particles—that normally infect potatoes—to serve as cancer drug delivery devices for mice. But in a recent article published in Nano Letters, the team showed injecting the virus particles alongside chemotherapy drugs, instead of packing the drugs inside, may provide an even more potent benefit.

Cheap, Energy-Efficient and Clean Reaction To Make Chemical Feedstock

They are all around you! Most plastics, conductive polymers, and even medicines derive from molecules with a double bond between two carbon atoms, C=C. These molecules are called olefins and are mainly produced from fossil fuels through an energy-intensive and polluting process known as steam cracking. It requires temperatures of 800°C and produces the greenhouse gas carbon dioxide. Needless to day, alternatives to this process which could bring environmental and economic benefits are highly sought after.

Fish living in extreme environments adapt ability to see

Cell biologists at the University of Toronto have discovered animals can adapt their ability to see even with extreme changes in temperature.

The researchers looked deeply into the eyes of catfish living in cold-water streams at altitudes of up to nearly three kilometres in the Andes Mountains to find out how. Their findings are published in Proceedings of the National Academy of Sciences.

Lake Harvests are Likely More Fruitful than We Knew

Harvests from freshwater fisheries such as the Great Lakes could total more than 12 million tons a year globally and contribute more to global food supplies and economies than previous estimates indicate, according to a study published today by Michigan State University and the U.S. Geological Survey.
