  Washington DC (SPX) Aug 20, 2021 The full Moon of Sunday, August 22nd, will be a "Blue Moon" according to the original - but not the most popular - definition of the phrase. In modern usage, "Blue Moon" has come to refer to the second full Moon in a month (the last of these occurred on October 31, 2020) - but that hasn't always been the case. This colorful term is actually a calendrical goof that worked its way into the pages of Sky and Telescope in March 1946 and spread around the world from there.

 Tokyo, Japan (SPX) Aug 16, 2021 
Precise metal nanoclusters (NCs) are ideal for developing practical catalysts for chemical reactions. However, their catalytic activity is reduced either due to protective molecules called "ligands" surrounding them or aggregation resulting from ligand removal. In a new study, scientists from Japan elucidate the ligand removal mechanism for gold NCs and irradiate them with UV light to prevent ag ... more |
