Scientists investigating mysterious dark matter

University of Houston scientists are helping to develop a technology that could hold the key to unraveling one of the great mysteries of science: what constitutes dark matter? Scientists believe dark matter makes up 85 percent ...

Predicting a new phase of superionic ice

Scientists predicted a new phase of superionic ice, a special form of ice that could exist on Uranus, Neptune, and exoplanets. This new type of ice, called P21/c-SI phase, occurs at pressures greater than those found inside ...

Powerful new device for studying puzzling process

A millisecond burst of light on a computer monitor signaled production of the first plasma in a powerful new device for advancing research into magnetic reconnection—a critical but little understood process that occurs ...

Hawking, the man whose brain transcended disability

Living with motor neurone disease for more than 50 years, Stephen Hawking transcended his disability to becoming one of science's brightest stars, harnessing technology to once again give voice to his ideas.

World mourns British scientist and cultural icon Hawking

World dignitaries, celebrities and academics on Wednesday mourned Stephen Hawking, the British physicist who died aged 76 after a cosmic career in which his mental genius transcended his physical disability to probe the secrets ...
