"Revolutionizing Home Appliances: The Magnetohydrodynamic Drive Takes Over the Kitchen Sink"

Originally Published 2 years ago — by Hackaday

A YouTuber named Jay Bowles has successfully experimented with a magnetohydrodynamic (MHD) drive, a propulsion technology that uses magnets and electrodes to silently propel a craft through water. By using a pair of electrodes and a single magnet, he achieved measurable results with just a standard bench supply. Through various experiments, he found that the MHD drive is forgiving in terms of design specifics, with more power and bigger magnets resulting in higher velocity. However, the brass electrodes showed signs of wear and tear, raising questions about the drive's long-term durability.

Injectable Brain Implants: The Next Frontier in Neuroscience

Originally Published 2 years ago — by WIRED

Scientists have developed a gel that, when injected into bodily tissue, solidifies into an electrically conductive polymer, which could be used to create soft, flexible electrodes that can be implanted into the brain. The electrodes formed by the gel are just as soft and movable as the brain tissue around it, and the gel is apparently harmless. The team has tested the material in living zebra fish and dead leeches, and the electrodes seem safe. However, the electrodes might be able to successfully conduct electrical signals, but the team doesn’t have a solution for getting those signals out of the brain so that scientists can actually see them, or for sending in current so the electrodes can be used for brain stimulation.
