The meeting of CEOs and world leaders aims to come up with specific, profitable ways to address humanitarian issues and spur economic growth

An implant that instructs the immune system to fight cancer

CANCER is deadly because it comes from within and evades the body’s natural defences. Attempts to train the immune system to recognise and attack cancers have so far failed. But a new technique that uses doped implants is showing promise.

Understanding precisely how fluid boils in tiny "microchannels" has led to formulas and models that will help engineers design systems to cool high-power electronics in electric and hybrid cars, aircraft, computers and other devices.

Allowing a liquid to boil in cooling systems dramatically increases how much heat can be removed, compared to simply heating a liquid to below its boiling point, said Suresh Garimella, the R. Eugene and Susie E. Goodson Professor of Mechanical Engineering at Purdue University.

As companies move to trim off-site costs, Toyota uses StarCite event-planning software to manage more than 400 annual face-to-face gatherings

A world with fewer people would emit less greenhouse gases

FAMILY planning is five times cheaper than conventional green technologies in combating climate change. That is the claim made by Thomas Wire, a postgraduate student at the London School of Economics, and highlighted by British medics writing in the Lancet on September 19th.

The air inside aircraft could soon be cleaner and more comfortable to breathe

Imagine a car that runs on hydrogen from solar power and produces water instead of carbon emissions. While vehicles like this won't be on the market anytime soon, University of Wisconsin-Madison researchers are making incremental but important strides in the fuel cell technology that could make clean cars a reality.
