You don't even have to say something. Just a laser beam, and the doc tells you what you have and ever have had. A new study, made at the National Institute of Standards and Technology and the University of Colorado at Boulder, and published in the journal Optics Express, shows how molecules from the breath, mark... |

The biggest problem with computer chip minimization today is that the fabrication process of semiconductor chips only allows components larger than the laser light wavelength used in the photoresist process. Any attempts to create smaller structures than the light's wavelengths will ultimately result in the use ... |

Black holes are some of the most mysterious objects in the whole universe. Except a handful of properties, almost nothing is known about what lies beyond their event horizon, whether it's a wormhole, a ultra-dense singularity or some other structure we have no knowledge about. And here is the worst part of the p... |
