Waiting an hour for your clothes to dry could be worrisome when you need something in a rush, but an Indian-American researcher has found a way out. Viral Patel and his team of researchers at Oak Ridge National Laboratory in Tennessee have developed a dryer that could make doing laundry much quicker.

Called the ultrasonic dryer, it's expected to be up to five times more energy efficient than most conventional dryers and can dry a large load of clothes in half the time. It uses piezoelectric transducers to remove moisture. Basically, the dryer shakes the water out of the clothes, speeding up the process.

Biz tycoon offers cheaper Heathrow expansion plans
A UK-based Indian-origin business tycoon has drafted proposals for the expansion of London's Heathrow Airport, which he claims will be billions of pounds cheaper than the scheme for upgrade of one of the world's busiest airports.

Surinder Arora, founder and chairman of Arora Group of Hotels, has drawn up plans for a third runway at Heathrow, which he believes could be cheaper by £6.7 billion and less disruptive than the scheme cleared by the government last year.

Willie Walsh, chief executive of International Airlines Group which owns British Airways, described the plans as a "welcome alternative".

Professor's handheld device can screen cervical cancer
An Indian-American professor and her team have developed a new handheld, low-cost device that will soon check cervical cancer without using a painful speculum.

Nimmi Ramanujam and her team from Duke University in North Carolina said the 'pocket colposcope', which can connect to a laptop or mobile phone, could even lead to women being able to self-screen.

Ramanujam's "all-in-one device" resembles a pocket-sized tampon. Her team asked 15 volunteers to try the new integrated design and more than 80 per cent said they were able to get a good image.
