What is LIFI technology (vs WIFI)?

                                   
                 

I just watched on the TV the BBC feature on Create, Innovate, its feature on LIFI, another alternative and solution to crowded broadband at WIFI.  Lifi uses light vs rf of WIFI.  It uses LED light, a semiconductor that can turn on and off at billionths of a second (nanosecond) and thus gives it a capacity of 1 Gigabit vs. traditional wifi that peaks at 100 mbits.

It is a major breakthrough for the connected community and internet community that rely on wireless broadband connection.  It a product of 4 years of research at University of Versailles and conform to WIFI 802.11 Standards

Others say as BBC that it was discovered at Scotland by Martin Dawson and Harold Haas, in Universtiy of Strathclyde ,

Manufactured blood soon a reality?

Repost from bio News | June 3, 2013

Using blood donations in surgery or anemia could be sometimes dangerous.  They may contain viruses that are deadly, and they are of different ages causing the transfusion to be sometimes useless. The blood donation/transfusion is useful for patients with thessalimia  -  body does not synthesize its own blood. 

At Scottish Center for Regenerative Medicine  in Scotland scientists led by by Professor Marc Turner are close synthesizing blood from stem cells.

There is a problem though with scaling up of production.

What do you think of this technology?
