The International Space Station (ISS) National Laboratory highlighted the rapid growth of space-based R&D in its annual report, released today by the Center for the Advancement of Science in Space® (CASIS®). Over the past fiscal year, the ISS National Lab sponsored more than 100 payloads delivered to the orbiting laboratory—the second-highest annual total to date. Also this year, ISS National Lab-related results were published in 51 peer-reviewed articles—the most ever in a year—underscoring the vital role of the ISS National Lab in advancing scientific discovery and innovation.

A new study published today in JAMA Network Open explores the effects of both recent and lifetime cannabis use on brain function during cognitive tasks.

The study, the largest of its kind ever to be completed, examined the effects of cannabis use on over 1,000 young adults aged 22 to 36 using brain imaging technology. The researchers found that 63% of heavy lifetime cannabis users exhibited reduced brain activity during a working memory task, while 68% of recent users also demonstrated a similar impact.

This decline in brain activity was associated with worse performance on working memory - the ability to retain and use information to perform tasks. For example, working memory allows a person to follow instructions they’ve just been given or to mentally visualize and manipulate information, like solving a math problem.
