CURRENT MOON

The phases of the moon are caused by the relative positions of the earth, sun, and moon. The moon goes around the earth, on average, in 27 days 7 hours 43 minutes.

The sun always illuminates the half of the moon facing the sun (except during lunar eclipses, when the moon passes thru the earth's shadow). When the sun and moon are on opposite sides of the earth, the moon appears "full" to us, a bright, round disk. When the moon is between the earth and the sun, it appears dark, a "new" moon. In between, the moon's illuminated surface appears to grow (wax) to full, then decreases (wanes) to the next new moon.

The edge of the shadow (the terminator) is always curved, being an oblique view of a circle, giving the moon its familiar crescent shape. Because the "horns" of the moon at the ends of the crescent are always facing away from the setting or rising sun, they always point upward in the sky. It is fun to watch for paintings and pictures which show an "impossible moon" with the horns pointed downwards.

Laser Light Can Detect Potential Diseases Via Breath Samples
By blasting a person's breath with laser light, scientists have shown that they can detect molecules that may be markers for diseases like asthma or cancer. Just as bad breath can indicate dental problems, excess methylamine may signal liver and kidney disease, ammonia may be a sign of renal failure, elevated acetone levels can indicate diabetes and nitric oxide levels can be used to diagnose asthma, Ye said.

Ultrafast Lasers Uncover Electronic Behavior
Researchers have used ultrafast lasers to uncover a previously unseen type of collective electronic behavior in semiconductors, findings which may impact the design of new optoelectronic devices.

Quantum Dot Lasers: One Dot Makes All The Difference
Physicists have built micron-sized solid-state lasers in which a single quantum dot can play a dominant role in the device's performance. These highly efficient optical devices could one day produce the ultimate low-power laser for telecommunications, optical computing and optical standards.

Hexagonal boron nitride semiconductors enable cost-effective detection of neutron signals
Researchers have developed an alternative material -- hexagonal boron nitride semiconductors -- for neutron detection. This material fulfills many key requirements for helium gas detector replacements and can serve as a low-cost alternative in the future.
