Liquid antennas turn seawater into signal
Liquid antennas turn seawater into signal
The US Navy has created a device which turns a jet of sea water into an impromptu liquid antenna, creating a powerful, high frequency broadcast tower for ships, emergency situations and easy transportation.
Created by SPAWAR System Center Pacific, the sea water antenna uses the magnetic induction properties of salt to make ordinary ocean water transmit and receive radio signals. As the pillar of water is squirted through the current probe, a magnetic field is created and signal comes through to a hooked-up communication device.
Plus, depending on the height of the stream of water, you can get UHF, VHF and HF broadcasts, all from the same jet of H2O. You can even set up multiple jets of water, at different heights, to broadcast on different bands simultaneously. Handy.

Canadian scientists transform human skin into blood

Canadian scientists have transformed pinches of human skin into petri dishes of human blood — a major medical breakthrough that could yield new sources of blood for transfusions after cancer treatments or surgery.
The discovery, by researchers at McMaster University in Hamilton, Ont., could one day potentially allow anyone needing blood after multiple rounds of surgery or chemotherapy, or for blood disorders such as anemia, to have a backup supply of blood created from a tiny patch of their own skin — eliminating the risk of their body’s immune system rejecting blood from a donor.
