Researcher proposes paradigm shift in enzyme biochemistry
Although you may never have heard of the cytochrome P450 superfamily of enzymes, these proteins play diverse and critical roles in humans through the metabolic processing of drugs, pesticides, fatty acids, fat-soluble vitamins, and chemical carcinoge.....»»
Variable star V708 Car has an unusual chemical composition, study finds
An international team of astronomers has performed spectroscopic observations of a variable star known as V708 Car. Results of the observational campaign, reported in a paper published February 20 on the pre-print server arXiv, indicate that this sta.....»»
Nanotweezers manipulate bacteriophages with minimal optical power, a breakthrough for phage therapy
Scientists at EPFL have developed a game-changing technique that uses light to manipulate and identify individual bacteriophages without the need for chemical labels or bioreceptors, potentially accelerating and revolutionizing phage-based therapies.....»»
AI-driven lab speeds catalysis research
Researchers have developed a "self-driving" lab that uses artificial intelligence (AI) and automated systems to provide in-depth analyses of catalytic reactions used in chemical research and manufacturing. The new tool, called Fast-Cat, can provide m.....»»
