London, Mar 23 : A robot's eyes may not be the windows to its soul, but they can certainly help humans guess the machine''s intentions, according to a new study.

Researchers led by Bilge Mutlu at Carnegie Mellon University, Pittsburgh, have demonstrated that robots "leak" non-verbal information through eye movements when interacting with humans.

Mutlu said that humans constantly give off non-verbal cues and interpret the signals of others, without realising it at a conscious level.

Washington, March 23 : Scientists working with the Fermilab atom smasher in Illinois, US, have discovered an unexpected new subatomic particle, which may break all known rules for creating matter.

It's long been accepted that six different "flavors" of particles called quarks combine to form larger subatomic particles.

Washington, March 20 : A team of scientists has confirmed the origin of supernovae as being produced from dying red supergiant stars.

The scientists are from the Dark Cosmology Centre at the Niels Bohr Institute, University of Copenhagen and from Queens University, Belfast.

A star is a large ball of hot gas and in its incredibly hot interior hydrogen atoms combine to form helium, which subsequently forms carbon, other heavier elements and finally iron.

When all the atoms in the centre have turned to iron the fuel is depleted and the star dies.

Washington, March 20 : An international team of scientists has come a step closer to understanding the Universe with the discovery of a fundamental building block of nature.

The recent discovery of a single top quark at the U. S. Department of Energy’s Fermi National Accelerator Laboratory near Chicago is a major breakthrough in understanding matter and energy.
