Sensing ultraviolet light with the help of molecular switches
The old saying "the dose makes the poison" also holds true for ultraviolet (UV) light. While UV light is essential for vitamin D production, it is also important in phototherapy, several industrial processes, and plant growth. It also has harmful eff.....»»
AI-powered optical detection to thwart counterfeit chips
The semiconductor industry has grown into a $500 billion global market over the last 60 years. However, it is grappling with dual challenges: a profound shortage of new chips and a surge of counterfeit chips, introducing substantial risks of malfunct.....»»
The winner in China"s panda diplomacy: the pandas themselves
China's panda diplomacy may have one true winner: the pandas themselves. Decades after Beijing began working with zoos in the U.S. and Europe to protect the species, the number of giant pandas in the wild has risen to 1,900, up from about 1,100 in th.....»»
