“This warming trend is alarming,” said NASA Administrator Bill Nelson. “Our warming climate is already making a mark: Forest fires are intensifying; hurricanes are getting stronger; droughts are wreaking havoc and sea levels are rising. NASA is deepening our commitment to do our part in addressing climate change. Our Earth System Observatory will provide state-of-the-art …

Most importantly, they unveiled the interfacial dynamics of solid-solid (between halide perovskite molecules) and solid-liquid (between a halide perovskite and an electrolyte) interfaces during photoelectrochemical hydrogen production. The latest findings open up an avenue to develop a more efficient solar-driven method for producing hydrogen fuel in the future. Hydrogen is considered to be a better …

That is one key finding of a new study from MIT researchers that explored the potential energy consumption and related carbon emissions if autonomous vehicles are widely adopted. The data centers that house the physical computing infrastructure used for running applications are widely known for their large carbon footprint: They currently account for about 0.3 …

Even the precursors to birds — extinct bird-like dinosaurs — benefited from folding their wings during the upstroke, as they developed active flight. Among flying animals alive today, birds are the largest and most efficient. This makes them particularly interesting as inspiration for the development of drones. However, determining which flapping strategy is best requires …

The Institute for the Ocean and Fisheries at UBC, British Columbia Ministry of Agriculture and Food, and Fisheries and Oceans Canada scientists analyzed tissue samples from six southern resident killer whales and six Bigg’s whales stranded along the coast of B.C. from 2006 to 2018, according to a recent study. They discovered that chemical pollutants …

When clothing made from plastic fibers, such as polyester and nylon, are laundered, the fabric sheds microscopic fibers that eventually end up in wastewater and the environment. Though researchers have investigated the amount and types of microplastic fibers shed while laundering clothing, most studies have focused on washing machines. In many countries, however, it is …

“Those same reasons that make sound so advantageous for animals to use also make them susceptible to disturbance from noise in the environment,” says first author Pernille Sørensen of the University of Bristol, Bristol, UK. “Within the last couple of decades, we’ve seen a dramatic increase in human-made noise, and noise pollution in the oceans …

While studies have shown that noise pollution affects cognitive performance in some animal species including birds, a study by Florida Atlantic University is the first to test whether exposure to this noise has any effects on a bird’s beak. For the study, researchers tested a songbird — the zebra finch (Taeniopygia guttata). Males have a …

The genetic variations linked to urbanization underlie physical differences in the urban lizards, including longer limbs and larger toe pads that show how these lizards have evolved to adapt to city environments. Urbanization has dramatically transformed landscapes around the world — changing how animals interact with nature, creating “heat islands” with higher temperatures, and hurting …

Missing Plastic Paradox Since the mass production of plastics began in the 1950s, a significant portion of plastic waste has made its way to the ocean via rivers, blown of from land by winds or directly dumped from ships. But the amount of plastic that is actually found in the ocean is only a fraction …
