Earlier this month NPR health correspondent Rob Stein introduced us to Victoria Gray, the woman at the center of a groundbreaking medical treatment using CRISPR, the gene-editing technique. This week, Rob reports exclusively for NPR on the first results of that closely-watched experiment. Follow host Maddie Sofia on Twitter @maddie_sofia. Email the show at shortwave@npr.org.

Happy World Toilet Day! Flushing toilets can consume a lot of water, so Tak-Sing Wong, a biomedical engineer at Penn State University, is trying to minimize how much is needed. Wong developed a slippery coating for the inside of a toilet bowl. It can potentially move human waste more efficiently, leaving a cleaner bowl and using less water.

Can machines read our minds? We go in search of the latest efforts to connect brains to computers. We learn how researchers are combining brain scans with machine learning to generate large amounts of information. We explore how this technology might be used to help people with serious medical conditions like locked-in syndrome. And discover there are many hurdles to overcome along the way – for example how can scientist develop implants that can access the brain without causing long-term damage? Our listener Daniel wants to know whether we might finally be on the cusp of enabling machines to meld with our minds.

For decades science fiction has been imagining the incredible ways that machines might interact directly with our minds, from enabling telepathic communication to controlling robotic suits, solely using the power of thought. Getting computers to interface directly with the human brain has proven extremely challenging, but rapidly advancing computer technology is changing the landscape. CrowdScience listener Daniel wonders if we might finally be on the cusp of enabling machines to meld with our minds. To find out, presenter Alex Lathbridge goes in search of the latest efforts to connect brains to computers. He learns how researchers are combining brain scans with machine learning and gets to test whether an fMRI machine can decode his emotions. He then meets someone with a brain implant but discovers there are many hurdles to overcome before these become mainstream in clinical practice – for example, how can scientists develop implants that won’t damage the brain? With tech companies like Facebook and Elon Musk’s Neuralink starting to invest in this sector, many experts believe it is only a matter of time before thoughts are ‘readable’. Whilst currently this technology is focussed on helping people with serious medical conditions, other potential applications for it are raising ethical considerations. Could it be possible to read someone's mind against their will? Might this be used in warfare? Listener Daniel wonders how far this technology might go, leading Alex to ask an ethicist what mind-reading technology might do to society.

While doing field work in Central America in the 1990's, biologist Karen Lips noticed the frogs she was studying were disappearing. Scientists in other parts of the world had documented the same thing - frogs and amphibians dying at an alarming rate. For years no one knew what was killing the animals until, finally, a bit of good luck helped solve the mystery. Follow host Maddie Sofia on Twitter @maddie_sofia.

The private space company run by Elon Musk launched 60 satellites into orbit this week. Science correspondent Geoff Brumfiel explains why astronomers worry that kind of traffic — if it continues unabated — could permanently alter their ability to observe the night sky.

NPR science correspondent Dan Charles explains why most of the dairy cows in America are descended from just two bulls, creating a lack of genetic diversity that can lead to health problems. He also visits a lab at Penn State University where scientists are trying to change that. Follow reporter/host Emily Kwong on Twitter @emilykwong1234. Email the show at shortwave@npr.org.
