Robert Downey Jr. is famous for being a beloved Hollywood actor, but now he is adding "robotics environmentalist" to his list of good qualities. Earlier this week, the Iron Man actor took to the stage at the Amazon Re: Mars conference in Las Vegas to announce the creation of his new foundation which will use nanotechnology (纳米技术) and robotics as a means of cleaning up the planet.
Downey Jr. did not show many details on how the organization will begin its clean-up job, but a website went live shortly after the actor's announcement. As of right now, the website only includes a sign-up sheet for future newsletters and latest news, but Downey Jr. says that he will be spending the next 11 months working together with UN experts and building up the organization so the group can get to work by April 2020.
After that, Downey Jr. says that "between robotics and nanotechnology we could probably clean up the planet noticeably, if not entirely, within a decade." Downey Jr. also explained how his failure to look after the environment in the past is now inspiring him to take action, "I have this quiet sense of crisis (危机)," he said, according to reporters. "I'm a person who spends a lot of energy on things like plane trips, but I want to change." Regardless of the actor's plan, Downey Jr's net worth is about $81 million-more than enough to start tidying up the planet.
The Re: Mars conference, which stands for "Machine learning, Automation, Robotics and Space", hosted a lot of speakers who gave lectures on the benefits of artificial intelligence. In addition to announcing the start of his organization, Downey Jr. also talked about how he and his wife Susan will be the managing producers of a new documentary series on the wonders of AI.

Smiling really can make people feel happier, according to a new study. American psychologists (心理学家) looked at nearly 50 years of data testing whether facial expressions can lead people to feel the emotions related to those expressions. They found smiling made people feel happier; frowning (皱眉) made them feel angrier or sadder.
However, the effects are not so strong, and the researchers warn this should hardly be held up as a way to offset weak mental health conditions like depression. Lead researcher Nicholas Coles said: "Ordinary wisdom tells us that we can feel a little happier if we simply smile. Or that we can get ourselves in a more serious mood if we frown. But psychologists have actually disagreed about this idea for over 100 years."
The research team says the disagreements became more pronounced in 2016, when 17 teams of researchers failed to copy a well-known experiment showing that the physical act of smiling can make people feel happier. Coles said: "Some studies have not found evidence that facial expressions can influence emotional feelings. But we can't focus on the results of any one study. Psychologists have been testing this idea since the early 1970s, so we wanted to look at all the evidence."
Using a data technique called meta-analysis (荟萃分析), the team collected data from 138 studies testing more than 11, 000 people from all around the world. The results of the meta-analysis suggest that facial expressions have a small influence on feelings.
Coles added: "We don't think that people can smile their way to happiness. But these findings are exciting because they provide evidence about how the mind and the body affect each other to shape our experience of emotion. We still have a lot to learn about these effects, but this meta-analysis put us a little closer to understanding how emotions work."
