Sheryl WuDunn: Our century's greatest injustice

Sheryl WuDunn's book "Half the Sky" investigates the oppression of women globally. Her stories shock. Only when women in developing countries have equal access to education and economic opportunity will we be using all our human resources.

About Sheryl WuDunn
Sheryl WuDunn and her husband, Nick Kristof, won a Pulitzer for their New York Times coverage of the 1989 Tiananmen Square protests. Their joint reporting work in China and other developing nations convinced them both that, just as slavery was the moral issue of the 19th century, sex trafficking, gender-based violence and other abuses make women's rights the moral issue of the 21st.
In their book Half the Sky: Turning Oppression into Opportunity for Women Worldwide, WuDunn and Kristof make the case for empowering women as a means of development. Women tend to spend more on education, nutrition and business, the economic engines of growth in a community. And if we can find ways to develop the untapped potential of the millions of women who are now left uneducated, denied basic rights, oppressed and threatened -- we'll turn on a firehose of economic power that could transform the developing world.

MIT Inventors Create Robot Swarm for Mopping Up Oil Spills

Forget skimmer ships, top kill, and any gibberish that came out of James Cameron's mouth: MIT researchers have invented a super-absorbent robot that can lap up oil faster than you can say Deepwater Horizon.

Crap, where were these guys a few months ago?



Seaswarm, as they call it, basically works like a maxi pad. A patented hydrophobic nanofabric devours as much as 20 times its own weight in oil without collecting water. To capture the oil, the nanofabric's draped over a conveyor belt that's then dispatched on the surface of the ocean like "a rolling carpet," to quote Assaf Biderman, associate director of MIT's Senseable City Lab. The robot's entirely autonomous; it swims along, powered by a pair of solar panels.



Senseable City Lab is unveiling the first prototype at the Venice Architecture Biennale on Saturday. The hope's to produce a whole fleet of Seaswarms that'll be able to attack oil spills like, yes, a swarm of bees.

Scientists create 'dry water

The substance resembles powdered sugar and could revolutionise the way chemicals are used.

Each particle of dry water contains a water droplet surrounded by a sandy silica coating. In fact, 95 per cent of dry water is ''wet'' water.

Scientists believe dry water could be used to combat global warming by soaking up and trapping the greenhouse gas carbon dioxide.

Tests show that it is more than three times better at absorbing carbon dioxide than ordinary water.

Dry water may also prove useful for storing methane and expanding the energy source potential of the natural gas.

Dr Ben Carter, from the University of Liverpool, presented his research on dry water at the 240th National Meeting of the American Chemical Society in Boston.

He said: ''There's nothing else quite like it. Hopefully, we may see dry water making waves in the future.''
