It’s no secret that caffeine helps boost concentration skills in the short term. But, until recently, most scientists thought that caffeine offered little benefit for remembering information in the long term. A new study published in the journal Nature Neuroscience challenges the assumption that caffeine doesn’t do much for memory. In short, caffeine enhances memory for information learned a day earlier and, like many things, moderation is key—too little caffeine and there are no memory benefits, too much caffeine doesn’t give you that much bang for your buck either.
Autumn Radtke, a 28-year-old American CEO of bitcoin exchange firm First Meta, was found dead in her Singapore apartment on Feb. 28.
Local media are calling it a suicide, but Singapore officials are waiting for toxicology test results.
Radtke formerly worked with Apple and other Silicon Valley tech firms on developing digital payment systems.
Radtke’s death brings the number of questionable financial-sector deaths this year to eight.
