Science: NASA’s First Moon Mission In 50 Years, Robots That Look, Act Like People

Staff Writer Paul Voosen talks with host Sarah Crespi about plans for NASA’s first visit to the Moon in 50 years—and the quick succession of missions that will likely follow. 

Next, Eileen Roesler, an engineering psychologist at the Technical University of Berlin, discusses the benefits of making robots that look and act like people—it’s not always as helpful as you would think.

Science: What Is CRISPR And How Does It Work?

This revolutionary gene-editing system has taken science by storm. CRISPR is the basis of a revolutionary gene editing system. One day, it could make it possible to do everything from resurrect extinct species to develop cures for chronic disease.

CRISPR is a family of DNA sequences found in the genomes of prokaryotic organisms such as bacteria and archaea. These sequences are derived from DNA fragments of bacteriophages that had previously infected the prokaryote. They are used to detect and destroy DNA from similar bacteriophages during subsequent infections. 

Science Podcast: Rural U.S. Sanitation Crisis, Manta Rays & Magnetic Muons

The lack of adequate sanitation in parts of the rural US, and physicists reassess muons’ magnetism.

00:45 How failing sanitation infrastructure is causing a US public health crisis

In the US, huge numbers of people live without access to adequate sanitation. Environmental-health advocate Catherine Coleman Flowers tells us about her new book looking at the roots and consequences of this crisis, focusing on Lowndes County, Alabama, an area inhabited largely by poor Black people, where an estimated 90% of households have failing or inadequate waste-water systems.

10:13 Reassessing muons’ magnetic moment

A decade ago, physicists measured the ‘magnetic moment’ of the subatomic muon, and found their value did not match what theory suggested. This puzzled researchers, and hinted at the existence of new physics. Now, a team has used a different method to recalculate the theoretical result and see if this discrepancy remains.

Science: Computer AI That Debates, Sea Slugs Regrow Entire Bodies (Podcast)

A computer that can participate in live debates against human opponents.

In this episode:

00:43 AI Debater

After thousands of years of human practise, it’s still not clear what makes a good argument. Despite this, researchers have been developing computer programs that can find and process arguments. And this week, researchers at IBM are publishing details of an artificial intelligence that is capable of debating with humans.
