Researchers used a novel phosphate-activation reagent, 2-MeImIm-Cl, in an improved coupling reaction to increase the yield of ADP- or ATP-containing molecules. Unlike traditional reactions, the modified coupling reaction does not require protecting groups, is simple to perform and exhibits high reproducibility.

Kilpatrick This NASA/ESA Hubble Space Telescope image treats viewers to a wonderfully detailed snapshot of the spiral galaxy NGC 3430 that lies 100 million light-years from Earth in the constellation Leo Minor. Several other galaxies, located relatively … Read more

A new system for forecasting weather and predicting future climate uses artificial intelligence (AI) to achieve results comparable with the best existing models while using much less computer power, according to its creators. In a paper published in Nature, a team of researchers from Google, MIT, Harvard and the European Center for Medium-Range Weather Forecasts … Read more

The findings bring hope and urgency for World Mangrove Day, offering a pathway to recovery and highlighting the critical need … Read more

In problem 1, the flow around a blunt body subjected to the supersonic flow is solved. Problem 2 presents the shock wave reflection on the wall involving complex interaction phenomena. For both problems, this hybrid method shows accurate solutions without serious errors. Credit: Yokohama National University A team of scientists has developed a novel hybrid … Read more
