“This paper discusses the physics, engineering and mission architecture relating to a gram-sized interstellar probe propelled by a laser beam. The objectives are to design a fly-by mission to Alpha Centauri with a total mission duration of 50 years travelling at a cruise speed of 0.1c. Furthermore, optical data from the target star system is to be obtained and sent back to the Solar system. The main challenges of such a mission are presented and possible solutions proposed. The results show that by extrapolating from currently existing technology, such a mission would be feasible. The total mass of the proposed spacecraft is 23g and the space-based laser infrastructure has a beam power output of 15GW. Rurther exploration of the laser — spacecraft tradespace and associated technologies are necessary.”

The Associated Press is launching a series of stories called Future of Work that explore how workplaces across the U.S. and the world are being transformed by technology and global pressures. As more employers move, shrink or revamp their work sites, many employees are struggling to adapt. At the same time, workers with in-demand skills or knowledge are benefiting. Advanced training, education or know-how is becoming a required ticket to the 21st-century workplace.
Three Chinese internet majors have set up what is claimed to be the one of the largest open databases for artificial intelligence (AI) in the world, aimed at helping global talent advance AI research by harnessing the huge data pool generated by China’s 750 million internet users.
The platform wants to empower AI researchers and developers to advance their research without constraints of data resources, say its backers.

(SpaceX) SpaceX launched 6,400 pounds of supplies to the International Space Station on Monday afternoon, and the roughly 100,000 people watching the live video online got to experience a rare shot of the reusable portion of the rocket sticking its landing in real time.
It was SpaceX’s 40th Falcon 9 mission and 11th rocket launch this year.

In the study, 22-month-old rats — who were considered old — received stem cells from four-month-old rats.
Across the board, all of them experienced improved heart function, improved their exercise capacity by an average of 20 percent, and regrew hair faster than rats that didn’t receive the cells.
They also demonstrated longer heart cell telomeres.
