Researchers at SLAC National Accelerator Laboratory captured one of the fastest movements of a molecule called ferricyanide for the first time by combining two ultrafast X-ray spectroscopy techniques. They think their approach could help map more complex chemical reactions like oxygen transportation in blood cells or hydrogen production using artificial photosynthesis.
The air pollutant secondary organic aerosol (SOA) forms when ammonia and amines react with oxygenated species. When ammonia is present when alkenes react with ozone, SOA increases in size and numbers. This may be due to Criegee intermediates. New research found that a particular amine, dimethylamine, reacts 34,000 times faster with one version of the Criegee intermediate acetaldehyde oxide than with another version of the same compound.

A recent study by scientists at The University of Texas at Austin and collaborators found that many of the fossils from Germany’s Posidonia shale do not get their gleam from pyrite, commonly known as fool’s gold, which was long thought to be the source of the shine. Instead, the golden hue is from a mix of minerals that hints at the conditions in which the fossils formed.

Ammonia (NH3) is one of the most widely produced chemicals in the world, with a production of over 187 million tons in 2020. About 85% of it is used to produce nitrogenous fertilizers, while the rest is used for refining petroleum, manufacturing a wide range of other chemicals, and creating synthetic fibers such as nylon.
Rutgers study used a pioneering technique to deliver endocrine-disrupting aerosolized micro-nano-plastics to female lab rats.
Bacterial spores can survive for years, even centuries, without nutrients, resisting heat, UV radiation, and antibiotics. How inert, sleeping bacteria — or spores — spring back to life has been a century-long mystery.
Among families with children diagnosed with autism spectrum disorder, Johns Hopkins University researchers say they have found a link between chemical “marks” on DNA in the sperm of fathers and autistic traits in their 3-year-old children.
The researchers focused on 66 PFAS compounds for their study. These can be grouped into three categories: 1) PFAS groups that have been regulated for some time; 2) new PFAS that industry uses as substitutes for regulated PFAS; and 3) precursors that can degrade to other, more persistent PFAS.
For the rational design of new material compounds, it is important to understand the mechanisms underlying their synthesis.

Artificial intelligence.
A novel system uses the discovery that the actinide berkelium, when oxidized, does not form negatively charged ions in solutions of high nitric acid, as other actinides do. This means an anion exchange column can separate berkelium by absorbing other actinides with negatively charged ions. The new method is much faster than the previously used approach, and is easier, cleaner, and yields purer product.

Weight regains is a common problem for weight loss individuals. A number of studies have shown that weight loss in overweight people results in a reduction in whole-body energy expenditure. This reduction in energy expenditure is disproportionate across tissues, known as energetic mismatch which primarily originates from lean tissue, thus increasing weight regain risk.
