Mayo Clinic researchers discover cancer cells may move via wave stimulation
.... Wave Basics Waves are circular ruffled surface structures on the exterior plasma membrane of a cell that can be observed through a conventional light microscope. They form in response to stimulation from EGF and exist for 10 to 20 minutes before disappearing. Waves intrigue researchers because wave-based in...Kids behave and sleep better after tonsillectomy, study finds
...alled adenotonsillectomy when both the tonsils and structures called adenoids are removed, is now performed on a few hundred thousand children a year. Nearly half of them have the surgery because enlarged tonsils and adenoids block the flow of air through their throat and impair their ability to breathe, and mo...The $6 billion (hu)man is becoming reality, as bionics restores or expands humans' abilities
