The University of Chicago has combined small angle and wide angle x-rays with a laser to watch quick reactions in protein. The different types of rays show both the overall shape (small angle) and more detailed information (wide angle) of the molecule. Just how quick of reactions does this machine track? The rays began hitting [...]

stereoscopes revealed
June 1st, 2010 · No Comments · Physics
A kids’ toy that we all know and love, is the stereoscope.This preschool toy makes a flat image into a 3D image you may have always have wondered how this works. It is actually made of two pictures. Each picture is taken from a slightly different viewpoint that corresponds closely to the spacing of the [...]

Lasers Help Researchers Predict Birds’ Preferred Habitat
June 1st, 2010 · 1 Comment · Biology
Scientists have wondered for about fifty years now, where migratory birds, like the Black-throated Blue Warbler, will nest in the American forests. Now they can with a device by a NASA funded research team. The device remotely senses and predicts where birds will nest. The machine sends laser lights down from an airplane to the [...]

Longest-Lasting Light Bulb
June 1st, 2010 · 1 Comment · Physics, Uncategorized
The longest-lasting light bulb is the Centennial light. It is located in Livermore, California. It is still giving off light in the Livermore-Pleasanton Fire Department. It is 109 years old and has been turned off a small amount of times. Part of the reason why light bulbs burn out is caused by the turning them [...]

First off, what is a attosecond? It is one quintillionth (10^-18) of a second. Lasers can now generate light pulses down to 100 attoseconds which will allow real time measurements on ultrashort time scales. Light has a very high frequency. It is also an electromagnetic wave. The domain where we can see one oscillation of [...]

Scientists use stem cells in dental implants to grow teeth
June 1st, 2010 · 1 Comment · Biology
This article is about: Scientists use stem cells in dental implants to grow teeth. Teeth are one the most important part of our body system. We use our teeth everywhere. To eat food, to drink and etc. But as the age grow up, people will lose their teeth. It’s not because of unhealthy, but the [...]

Light Switch
June 1st, 2010 · No Comments · Biology, Physics
At the University of Wisconsin scientists have recently discovered how sunlight triggers plant growth. In which case the phytochrome acts as a “light switch” to trigger plant growth. This could be very useful in biological studies and human growth possibly. http://www.sciencedaily.com/releases/2010/05/100531155423.htm
