NASA's Mars Curiosity has debuted the first recorded human voice that traveled from Earth to another planet and back. The voice playback was released along with new telephoto camera views of the varied Martian landscape.

Frankenstein programmers test a cybersecurity monster

Posted: 27 Aug 2012 02:59 PM PDT

To catch a thief, you have to think like one. Computer scientists are trying to stay one step ahead of cyberattackers by creating their own monster. Their monster can cloak itself as it steals and reconfigures information in a computer program.

Cooled coal emissions would clean air and lower health and climate-change costs

Posted: 27 Aug 2012 11:21 AM PDT

Refrigerating coal-plant emissions would reduce levels of dangerous chemicals that pour into the air -- including carbon dioxide by more than 90 percent -- at a cost of 25 percent efficiency, according to a simple math-driven formula.

Controlling superconductors with light

Posted: 27 Aug 2012 09:25 AM PDT

By shining a light on a thin layer of molecules coating a material, scientists have been able to control the critical temperature at which the material can act as a superconductor. This method might be used to develop more powerful computing devices able to save data and run continuously without generating heat and wasting energy.

Laser beam as a '3-D painter' to grow biological tissue or to create micro sensors

Posted: 27 Aug 2012 04:41 AM PDT

With laser beams, molecules can be fixed at exactly the right position in a three dimensional material. The new method can be used to grow biological tissue or to create micro sensors.
