On this day in 1947, William Shockley, John Bardeen and Walter Brattain at Bell labs built the first practical point-contact transistor. You could argue that the entire semiconductor industry arose from this research.

Their experiment, consisted of a block of germanium, a semiconductor, with two very closely spaced gold contacts held against it by a spring. The germanium had a surface layer with an excess of electrons. When an electric signal traveled in through the gold foil, it injected holes (points which lack electrons). This created a thin layer which had a scarcity of electrons. A small positive current applied to one of the two contacts had an influence on the current which flowed between the other contact and the base upon which the block of germanium was mounted.

The point-contact transistor was commercialized and sold by Western Electric and others but was soon superseded by the bipolar junction transistor, which was easier to manufacture and more rugged.

You can read more about it in this 1992 article from our archive http://dx.doi.org/10.1063/1.881336 .

For the first time, scientists have built artificial enzymes using lab-grown genetical material called XNA. The experiment bolsters the idea that life could evolve without what we thought to be the fundamental building blocks of life - DNA and RNA....

Crystals owe their beautiful shapes to the highly structured pattern of bonds between atoms. Negative crystals are the same but they are the inverse of the crystal - they form around a void: http://bit.ly/1qXjqlX via New Scientist

It looks like some kind of alien virus, but that's a snowflake magnified 50,000 times. And those weird hair-like things on the end? Those are crystallised, supercooled cloud droplets.
