I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Study pinpoints process that might have led to first organic molecules” Credit: CC0 Public Domain New research led by the American Museum of Natural History and funded by NASA identifies a process that might have been key in producing the first organic molecules on Earth about 4 billion years ago, before the origin of life….
“#IBM announces AI based chemistry lab: RoboRXN” Credit: Pixabay/CC0 Public Domain IBM has announced on its blog page the development of an AI/cloud-based chemistry lab named RoboRXN. Its purpose is to help chemists develop new materials in a faster and more efficient way than the current trial-and-error process. For thousands of years, humans have devised…
“#Sulfur-scavenging bacteria could be key to making common component in plastic” Scientists have discovered how microbes in waterlogged soils produce high levels of ethylene, which can adversely affect agricultural crops and bioenergy feedstocks like switchgrass. This new knowledge can be used to develop treatments for healthier crops. Credit: Andy Sproles/ORNL, U.S. Dept. of Energy Scientists…
“#Bacterial enzymes ‘hijacked’ to create complex molecules normally made by plants” Credit: CC0 Public Domain Chemists at Scripps Research have efficiently created three families of complex, oxygen-containing molecules that are normally obtainable only from plants. These molecules, called terpenes, are potential starting points for new drugs and other high-value products—marking an important development for multiple…
“#Stopping listeria reproduction ‘in its tracks’” Electron micrograph of a flagellated Listeria monocytogenes bacterium, Magnified 41,250X. Credit: CDC/public domain Listeria contaminations can send food processing facilities into full crisis mode with mass product recalls, federal warnings and even hospitalization or death for people who consume the contaminated products. Destroying the bacterium and stopping its spread…
“#Researchers quantify, characterize and identify functions of collagen, its subtypes” Credit: University of California, Irvine Found in cartilage, bones, blood vessels, skin, and other connective tissues, collagens are the most abundant proteins by weight in the human body. In an article published recently in Nature Reviews Materials, UCI biomedical engineering researchers provide an exhaustive description…
“#Miami chemists’ breakthrough technique enables design at the interface of chemistry and biology” A synthetic polymer (teal tube) conjugated to a protein. The purple sleeve on the polymer is a reporting group, the key to Konkolewicz and Page’s technique.

“#Scientists stick to spider silk for biodegradable alternative to traditional glue” Credit: Pixabay/CC0 Public Domain Scientists have successfully produced synthetic spider silk to create a new biodegradable glue alternative. The Manchester University-based researchers found that their homemade synthetic spider silk glue works as well as commercially available adhesives without being environmentally harmful. The glue was…
“#Chemists develop bioinspired strategy for the controlled synthesis of polyenes” Light-driven flip of alkene geometry. Credit: Ryan Gilmour They occur in nature, are reactive and play a role in many biological processes: polyenes. It is no wonder that chemists have for a long time been interested in efficiently constructing these compounds—not least in order to…
“#Membrane technology could cut emissions and energy use in oil refining” New membrane technology could reduce carbon emissions and energy intensity associated with refining crude oil. Georgia Tech Associate Professor Ryan Lively shows a module containing the new membrane material, while Professor M.G. Finn holds vials containing some of the other polymers used in this…
