Users Are Suing Fitbit Over Inaccurate Heart Monitors
In a world’s first, researchers from the US and UK have created an impression of a submerged human as recorded by a dolphin’s echolocation. To do it, a team led by Jack Kassewitz of SpeakDolphin.com used an imaging system known as a Cymascope . The system, developed by John Stuart Reid (who also assisted with the project), made it possible to record and isolate dolphin echolocation sounds directed onto specific objects, and then create 2D images from those sounds. A computer then converted those images into 3D, which allowed the researchers to 3D-print robust, real-world models. “We’ve been working on dolphin communication for more than a decade, ” noted Kassewitz in a release. “When we discovered that dolphins not exposed to the echolocation experiment could identify objects from recorded dolphin sounds with 92% accuracy, we began to look for a way for to see what was in those sounds.” Read more…

Last year, scientists in China used a gene-editing technique to produce pint-sized pigs for medical research. Now they want to sell them as pets. Critics say the precedent could lead to bizarre versions of cats and dogs, while at the same time preventing biologists from focusing on more important research. Read more…
