Less is more: Why an economical iridium catalyst works so well
Iridium-based catalysts are needed to produce hydrogen using water electrolysis. Now, a team at HZB has shown that the newly developed P2X catalyst, which requires only a quarter of the iridium, is as efficient and stable over time as the best commer.....»»
Unlike other insects, desert ants may use polarity of geomagnetic field for navigation
Desert ants of the Cataglyphis nodus species use the Earth's magnetic field for spatial orientation, but these tiny insects rely on a different component of the field than other insects, a research team led by Dr. Pauline Fleischmann from the Univers.....»»

Beaver survey aims to show the urban benefits of Chicago"s "ecosystem engineers"
As the boat zipped down the Chicago River on a nippy November morning, Sammie Clark stood up and pointed at a creature swimming in the water, its brown fur slick and its head bobbing just above the surface. It kept close to the edge, a sheet metal wa.....»»
MAUVE: An ultraviolet astrophysics probe mission concept
For the past 30 years, NASA's Great Observatories—the Hubble, Spitzer, Compton, and Chandra space telescopes—have revealed some amazing things about the universe. In addition to some of the deepest views of the universe provided by the Hubble Dee.....»»
Biodegradable polymers show promise for nutrient encapsulation and replacing microbeads in beauty products
Microplastics are an environmental hazard found nearly everywhere on Earth, released by the breakdown of tires, clothing, and plastic packaging. Another significant source of microplastics is tiny beads that are added to some cleansers, cosmetics, an.....»»
Copenhagen takes on its biggest climate threat—water

3D scans of giant hailstones reveal surprising discoveries that could help predict future storms
Hailstones are formed during thunderstorms, when raindrops are propelled into very cold parts of a cloud, where they freeze. Once the particles are heavy enough, gravity pulls them back towards Earth. As they plummet, they grow into hailstones, which.....»»
Developing a cyclic molecule that captures phosphate in harmony with water molecules
Researchers at University of Tsukuba, Osaka University, and Kitasato University developed a novel amide cyclodextrin (cyclic oligosaccharide) that can selectively capture phosphate ions in water. In addition, the researchers revealed the mechanism by.....»»
UN report: Invest in nature to cut billion-dollar costs of droughts
As droughts fueled by human destruction of the environment are projected to affect 3 in 4 people by 2050, investing in sustainable land and water management is essential to reduce their costs, which already exceed $307 billion per year globally, acco.....»»
Environmental pollutant decreases by half after passing through digestive tract of marine worm in Japan, study finds
Dr. Atsuko Nishigaki and their research team from Toho University, discovered that the marine worm Marphysa sp. E, an annelid living in the tidal flat sediments of Tokyo Bay, rapidly decreased the concentration of polycyclic aromatic hydrocarbons (PA.....»»
Social media platforms are throttling access to news—with far-reaching implications for democracy
