Smartphones have a new role in medicine
I am sorry but I am not aware of a way to eliminate the advertisement before the video:
Gravity light
The people at deciwatt.org wanted to develop a device that
would provide free light in developing countries. They asked for $55,000 in support donations
at indiegogo.com. The pledges have
amounted to $400,000.
It is basically a device that works by suspending a bag full
of rocks and letting gravity turn a small generator which powers an LED. Current production cost is about $10 per unit
and with continued R&D they hope to bring the cost down to $5.
Lighting in rural areas of developing nations is largely
provided by kerosene. This is an
expensive proposition as well as being dangerous and unhealthy. The cost of a gravity light can be returned
in cost savings over kerosene in about three months.

King Richard III found
A skeleton found under a Leicester car park has been confirmed as that of English King Richard III. Compelling evidence reinforces earlier speculation that they had found the 500 year old grave. They should have that team work on finding Jimmy Hoffa.
Read the whole story at the BBC site.
