Link between insomnia and obesity

A possible link between lack of sleep (insomnia) and obesity has been traced to hypocretin/orexin cells in the hypothalamus region of the brain that are easily excited and sensitive to stress, Yale School of Medicine researchers report in the April issue of Cell Metabolism.

Cryoablation may be safer alternative for stopping abnormal electrical patterns

Freezing abnormal electrical pathways in the hearts of young patients may be a safer alternative to zapping them with powerful radiofrequency probes in order to treat tachycardias and other arrhythmias, according to a new study in the April 5, 2005, issue of the Journal of the American College of Cardiology.

Bionic eyes from Stanford

Stanford physicists and eye doctors have teamed up to design a "bionic eye," of sorts. On Feb. 22 in the Journal of Neural Engineering, Daniel Palanker, Alexander Vankov and Phil Huie from the Department of Ophthalmology and the Hansen Experimental Physics Laboratory and Stephen Baccus from the Department of Neurobiology published a design of an optoelectronic retinal prosthesis system that can stimulate the retina with resolution corresponding to a visual acuity of 20/80
