Within the next 12 months, as many as 10 million laptop computers will be distributed to children in Argentina, Brazil, Libya, Nigeria, Pakistan, Rwanda, and Uruguay. Countless youngsters who live in remote villages, perhaps without electricity, who may not have access to clean water or health care, will suddenly have computing power pretty close to that of businesspeople and college students.

–Mayo Clinic researchers have developed an artificial intelligence algorithm that can detect weak heart pump functioning from a single-lead electrocardiogram (ECG) on the Apple Watch. They say early results indicate it is as accurate as a medically-ordered treadmill stress test, but could be performed anywhere.

The single-lead AI algorithm was adapted from an existing algorithm that works by analyzing ventricular pumping data from a 12-lead ECG already in clinical use under an Emergency Use Authorization from the U.S. Food and Drug Administration (FDA).

Dr. Paul Friedman, chair of the clinic’s department of cardiovascular medicine, said the new technology could signal a new era for patients for whom making repeated trips to a hospital or cardiologist’s office are, at the least, inconvenient, and possibly health-threatening.

The next time humans land on the moon, they intend to stay awhile. For the Artemis program, NASA and its collaborators want to build a sustained presence on the moon, which includes setting up a base where astronauts can live and work.

One of the crucial elements for a functioning lunar base is a power supply. Sandia National Laboratories, a research and development lab that specializes in building microgrids for military bases, is teaming up with NASA to design one that will work on the moon.
