Washington, Sept 20 : Researchers at the Massachusetts Institute of Technology (MIT) have created a device that would lighten the burden for soldiers and others who carry heavy packs and equipment.

Their invention, known as an exoskeleton, can support much of the weight of a heavy backpack and transfer that weight directly to the ground, effectively taking a load off the back of the person wearing the device.

Washington, September 20 : A new study conducted at two universities in Manchester has revealed that microwaves, which are used for zapping instant meals, can also be used to determine the fat and salt content of supermarket food.

Sing Kwei Ng, a student of PhD and one of the researchers behind the study, has won a top industry prize for his work to determine the amount of fat in beef.

Washington, Sept 20 : Geochemists at Rensselaer Polytechnic Institute have challenged the commonly held ideas about how gases are expelled from the Earth.

The team, lead by Prof E. Bruce Watson, has found strong evidence that argon atoms are tenaciously bound in the minerals of Earth’s mantle and move through these minerals at a much slower rate than previously thought.
