If you want to build a fully functional nanosized robot, you need to incorporate a host of capabilities, from complicated electronic circuits and photovoltaics to sensors and antennas.
But just as importantly, if you want your robot to move, you need it to be able to bend.

Sam Altman, the co-founder and president of San Francisco-headquartered tech nonprofit OpenAI, says AI will generate enough wealth to pay each adult $13500 a year.
Today on the Science Talk podcast, Noam Slonim speaks to Scientific American about an impressive feat of computer engineering: an AI-powered autonomous system that can engage in complex debate with humans over issues ranging from subsidizing preschool and the merit of space exploration to the pros and cons of genetic engineering.
In a new Nature paper, Slonim and colleagues show that across 80 debate topics, Project Debater’s computational argument technology has performed very decently—with a human audience being the judge of that. “However, it is still somewhat inferior on average to the results obtained by expert human debaters,” says Slonim.

‘Skybrators’ generate clean energy without environmental impact of large windfarms, say green pioneers.
“The research is part of an explosion of new techniques and ideas for studying early development. Today, in the same issue of Nature, two other research groups are reporting a leap forward in creating ”artificial” human embryos.
Those teams managed to coax ordinary skin cells and stem cells to self-assemble into look-alike early human embryos they call ”blastoids,” which they grew for about 10 days in the lab. Several kinds of artificial models of embryos have been described before, but those described today are among the most complete, because they possess the cells needed to form a placenta. That means they are a step closer to being viable human embryos that could develop further, even until birth.
Scientists say that they would never try to establish a pregnancy with artificial embryos—an act that would be forbidden today in most countries.

Dr James Desmond, DVM, Co-Founder, Liberia Chimpanzee Rescue & Protection (LCRP), discussing his work at LCRP, as well as his zoonotic disease surveillance work with EcoHealth.
Liberia Chimpanzee Rescue & Protection (LCRP — https://www.liberiachimpanzeerescue.org/) is the first and only chimpanzee sanctuary and conservation center in Liberia rescuing chimpanzees who are victims of the illegal bush meat and pet trades. The organization has over 40 orphaned chimpanzees, nearly all under the age of five, currently under their care.

A theoretical way to create a sub-light warp drive has been described that does not require negative mass. This could enable fast travel through our Solar System and onwards to distant star systems.
As technology for manipulating embryonic life accelerates, researchers want to get rid of their biggest stop sign.
