Electrochemical catalysts used in water splitting often show poor performance due to low electrical conductance of (oxy)hydroxide species produced in situ. To overcome this challenge, researchers have now designed an electrode with Schottky Junction formed at the interface of metallic Ni-W5N4 and semiconducting NiFeOOH. The proposed electrode shows excellent catalytic activity and can facilitate industrial seawater splitting continuously for 10 days.

Recently, morning omelets and holiday dinners have gotten more expensive. One likely cause is bird flu, outbreaks of which led to the deaths of millions of chickens and turkeys from infection or culling in 2022, according to the U.S. Department of Agriculture, and which still demands rigorous monitoring of wild populations. Now, researchers have developed a method that detected infectious bird flu virus in wetlands frequented by waterfowl.

Newly discovered iron storage 'ferrosomes' inside the bacterium C. diff -- the leading cause of hospital-acquired infections -- are important for infection in an animal model and could offer new targets for antibacterial drugs. They also represent a rare demonstration of a membrane-bound structure inside a pathogenic bacterium, upsetting the biological dogma that bacteria do not contain organelles.

From the depths of the seas to snow on mountains and even the air above cities, microplastics are turning up increasingly often. Now, researchers have analyzed microplastics in clouds above mountains. They suggest that these tiny particles could play a role in cloud formation and, in turn, affect weather.

Researchers present evidence of previously unknown luminosity in 10 deep-sea species, suggesting underestimated diversity. These new discoveries include a member of the order Molpadia, which was previously thought not to be luminescent. The authors stress the importance of considering the ecological role of bioluminesence and the need for conservation.

As the world continues to warm, Antarctica is losing ice at an increasing pace, but the loss of sea ice may lead to more snowfall over the ice sheets, partially offsetting contributions to sea level rise.

Researchers have found that the deadly deformed wing virus (DMV) in bees may have evolved to be less deadly in at least one U.S. forest. The findings could have implications for preventing or treating the virus in managed colonies, researchers said.

It's one of the most famous taglines in film history, immortalizing sharks as ruthless predators. But beyond the horror generated by Spielberg's Jaws series, a persistent fear of sharks remains, with consequences that extend into reality.

Naturalized species, which are not native but have established themselves in new locations, have the potential to spread even further to suitable habitats in many parts of the world, reports a new study.

Exposure to ultrafine particles from traffic alters the expression of many genes in human olfactory mucosa cells, a new study shows. The study is the first to combine an analysis of emissions from different diesel fuels and exhaust after-treatment systems with an examination of their effects in a human-derived cell model of the olfactory mucosa.
