Leadless pacemakers are devices that are as small as a capsule and are small enough to allow the generator to be placed within the heart, therefore avoiding the need for pacing leads. [11] As pacemaker leads can fail over time, a pacing system that avoids these components offers theoretical advantages.
The physiology of plant memory is documented in many studies and is understood to have four main physiological mechanisms that work together in synchrony to provide the plant with basic memory functions, and are thought to be precursors to advanced memory functions found in animals. These four mechanisms are the storing and recalling ...
Plant communication encompasses communication using volatile organic compounds, electrical signaling, and common mycorrhizal networks between plants and a host of other organisms such as soil microbes, [2] other plants [3] (of the same or other species), animals, [4] insects, [5] and fungi. [6]
Pacemakers and other electronic implants are a pain to keep running -- patients need surgery to replace batteries, and body-powered generators aren't currently strong enough to charge these devices.
An artificial cardiac pacemaker (or artificial pacemaker, so as not to be confused with the natural cardiac pacemaker) or just pacemaker is an implanted medical device that generates electrical impulses delivered by electrodes to the chambers of the heart either the upper atria, or lower ventricles to cause the targeted chambers to contract and ...

Plant intelligence (also known as plant cognition or plant neurobiology) is a field of plant biology which aims to understand how plants process the information they obtain from their environment. [ 2 ] [ 3 ] [ 4 ] Plant neurobiological researchers claim that plants possess abilities associated with cognition including anticipation, decision ...
St. Jude Medical was founded in 1976 to further develop bi-leaflet artificial heart valves, which were originally created in 1972 at the University of Minnesota. [4] [5] St. Jude Medical's bi-leaflet valve was developed in large part by Dr. Demetre Nicoloff of the University of Minnesota and St. Jude Medical employee Don Hanson.
