With the help of cat owners, a new project investigates cats’ biology and aims to link some of their behaviors to their genes.Calling all cat people: This one’s for you. Despite humans’ long history of welcoming felines into their homes and delis, research on cats lags far behind research on dogs. Now, scientists behind the project Darwin’s Ark are working to close the cat gap by enlisting cat caretakers from across the country to submit a tuft of fur and answer a few questions about their feline’s appearance, personality, and behaviors.Host Flora Lichtman talks about the project, as well as what we do and don’t know about cat genetics, with Dr. Elinor Karlsson, chief scientific officer at Darwin’s Ark, and director of the Vertebrate Genomics Group at the Broad Institute of MIT and Harvard Universities.Transcript for this segment will be available after the show airs on sciencefriday.com.

An evolving technology is changing the lives of people with paralysis: brain-computer interfaces (BCI). These are devices that are implanted in the brain and record neural activity, then translate those signals into commands for a computer. This allows people to type, play computer games, and talk with others just by thinking, allowing more freedom to communicate.For decades, this technology has looked like a person controlling a cursor on a screen. But this work has advanced, and in a recent breakthrough, a person with paralysis in all four limbs was able to move a virtual quadcopter with extreme precision by thinking about moving it with their fingers.Another area of BCI research involves speech. Recent work has shown promise in allowing people with vocal paralysis to “speak” through a computer, using old recordings to recreate the person’s voice from before their paralysis.Joining Host Flora Lichtman to discuss the state of this technology, and where it may be headed, are Dr. Matthew Willsey, assistant professor of neurosurgery and biomedical engineering at the University of Michigan, and Dr. Sergey Stavisky, assistant professor of neurosurgery and co-director of the Neuroprosthetics Lab at the University of California, Davis.Transcript for this segment will be available after the show airs on sciencefriday.com.

In Connecting Dots: A Blind Life, inventor Josh Miele recounts his life story and path to becoming an accessibility designer.When inventor and scientist Josh Miele was 4 years old, a neighbor poured sulfuric acid on his head, burning and permanently blinding him. In his new book Connecting Dots: A Blind Life, Miele chronicles what happened afterwards, growing up as a blind kid, and how he built his career as an inventor and designer of adaptive technology.Host Flora Lichtman talks with Dr. Joshua Miele, an Amazon Design Scholar and MacArthur Fellow, or “Genius Grant” recipient. They talk about the inspiration for the book, how he grew into his career, and how disabled people need to be included in the technology revolution.Transcript for this segment will be available after the show airs on sciencefriday.com.  Subscribe to this podcast.
