Flamingoes get their color from their food, but then also convert some of the relevant substances before depositing them in their feathers. The reddish-pink color of marine organisms such as freshwater algae, shrimp, lobster, and salmon mainly comes from astaxanthin. Flamingos eat algae and brine shrimp, thus taking up astaxanthin. Then, some of this astaxanthin is converted into a similar molecule, canthaxanthin, in their livers, in a reaction that chemically can be described as a reductive dehydroxylation (the hydroxyl groups at two carbon atoms are converted into hydrogen). This is catalyzed by carotenoid dehydrogenases/oxidases. The canthaxanthin is then deposited into the feathers of the flamingos, which is the main contributor to the pink color…...

20+ hour, 55+ min ago (696+ words) Researchers in Finland have shown that simple molecules related to everyday oils, plus visible light, can dissolve silver without relying on harsh chemicals." The same chemistry can pull silver from waste and then return it as solid metal ready for reuse. Today, only around one fifth of global silver supply comes from recycling. This is despite the fact that demand keeps rising in electronics and solar panels." Scientists call this urban mining, recovering metals from discarded products instead of digging new ore. The new chemistry helps make that recovery even more practical. Work on the new recycling route was led by postdoctoral researcher An'e Zupanc at the University of Helsinki. His research focuses on using simple organic molecules as tools for cleaner metal recovery. For more than a century, many mines have used cyanide leaching to pull metals from crushed…...

1+ day, 12+ hour ago (667+ words) A new study has found that many everyday chemicals can harm the good bacteria living in your gut. These bacteria are important for keeping your body healthy, but researchers have discovered that 168 different human-made substances can stop these microbes from growing properly. Many of these chemicals are found in food, drinking water, and the environment, but until now, they were not believed to affect gut bacteria. The study was done by scientists at the University of Cambridge. They tested over 1,000 different chemicals to see how they affected 22 common types of gut bacteria in a lab setting. These chemicals included pesticides like herbicides and insecticides used on crops, and industrial chemicals found in plastics and flame retardants. Our gut is home to thousands of different kinds of bacteria that help with digestion, the immune system, mental health, and more. If something…...

1+ day, 12+ hour ago (428+ words) A rocky exoplanet outside the Earth's solar system may have an atmosphere, according to new evidence gathered by NASA researchers. The exoplanet's low density has surprised and baffled scientists, NASA said. It may have an unusual composition from planets in Earth's solar system. It could also be surrounded by a thick atmosphere, which would not be expected on an exoplanet with these features. But the James Webb Space Telescope helped scientists gather data that showed that unlikely scenario might be the case. Researchers used the telescope's Near-Infrared Spectrograph to measure the exoplanet's dayside temperature. If the exoplanet has no atmosphere, scientists estimated its dayside temperature would be about 4,900 degrees Fahrenheit. But the spectrograph found TOI-561b's temperature closer to 3,200 degrees Fahrenheit, far cooler than expected. Just determining the temperature of the exoplanet doesn't confirm if there is an atmosphere there,…...
