These give out a continuous spectrum of light, and thus affect a wide range of frequencies that are of interest to astronomers.

Users can simply mount the entire flashlight and charger as a unit by doorways and entryways to hazardous locations, thus providing a highly convenient and fully charged portable light source whenever it is needed.

These results thus shed light on why, in a series of clinical trials conducted last autumn, leptin treatment did not prove uniformly effective (let alone miraculous).

In a process similar to printing a photograph, engineers beam high-powered light through a masklike image of the chip, thus creating a duplicate on a silicon wafer.

But during the trial Astra brought in a drug-delivery expert from the University of Nottingham who analyzed Andrx's pellets under a microscope with infrared and ultraviolet light and concluded they contain a third layer after all, thus infringing Astra's patents.

FORBES: Hard to Swallow

One way to control this process is to use two beams that, when they cross, double the amount of light in a spot, and thus cause the liquid to solidify faster.

Just last month, scientists announced they had found a planet very likely to have liquid oceans (and thus the potential for life) 22 light years from the Earth.

Holiness thus doesn't require a change in external circumstances, but a change in attitude, seeing everything anew in the light of one's supernatural destiny.
