Astronomers took this image as they were observing an extraordinary exploding star – a supernova – near the galaxy’s central yellow core! The star rapidly evolved from a supernova containing very little hydrogen to one that is hydrogen-rich — in just one year. This rarely observed metamorphosis was luminous at high energies and provides unique insight into the poorly understood final phases of massive stars. By studying similar galaxies we hold a scientific mirror up to our own, allowing us to build a better understanding of our galactic environment, which we cannot always observe, and of galactic behavior and evolution as a whole.

The death penalty, abortion, gun legislation: There’s no shortage of controversial topics that are hotly debated today on social media. These topics are so important to us because they touch on an essential underlying force that makes us human, our morality.

Researchers in Brazil have developed and analyzed three models that can describe the morality of individuals based on the language they use. The results were published last month in IEEE Transactions on Affective Computing.

“I’ve never seen a better time for this industry,” said Mark Edelstone. “Chips are cool again.”

Edelstone, who is chairman of global semiconductor investment banking for Morgan Stanley, and has some 30 years of experience in the chip business, was speaking on a panel at the annual semiconductor forum held (virtually this year) by startup incubator Silicon Catalyst. He was not alone in his assessment.
