Scientists have devised a new method for mapping the spottiness of distant stars by using observations from NASA missions of orbiting planets crossing their stars’ faces. The model builds on a technique researchers have used for decades to study star spots. By improving astronomers’ understanding of spotty stars, the new model — called StarryStarryProcess — can help discover more about planetary atmospheres and potential habitability using data from telescopes like NASA’s upcoming Pandora mission.

Harvard researchers have created an electro-optic digital-to-analog converter that bridges electronic and photonic signals for efficient photonic computing and signal processing.

Indoles, which form the backbone of many bioactive compounds, are valuable in drug development but are difficult to modify at certain positions. Researchers at Chiba University have developed a cost-effective method using a copper-based catalyst to selectively attach alkyl groups to the C5 position, which has been especially challenging to target. This approach simplifies the synthesis of indole-based precursors and is expected to lead to the development of novel drug candidates in the future.
