Most snowflakes are hexagons because of the arrangement of hydrogen bonds in the water molecule. But the new study, appearing online at arxiv.org (http://arxiv.org/abs/0911.4267) and in an upcoming issue of The Microscope, suggests that after hexagonal flakes, oddball triangular flakes are the most prevalent.
Study coauthors Kenneth Libbrecht and Hannah Arnold of Caltech in Pasadena propose an aeronautical reason for the triangular geometry. The results help solve the very old puzzle of how the unexpected flakes form, Libbrecht says.
Snowflake enthusiasts — such as Libbrecht, who photographs snowflakes — have spotted triangular snowflakes in the wild. The snowflake scientific literature, which goes back almost two centuries, is thick with such sightings, Libbrecht adds, but no one has explained why. “People have noticed them for hundreds of years.”

Snowflakes in Interest Thursday, December 3, 2009 at 9:41AM Inventor Dean Kamen unveils the Segway Personal Transporter, a two-wheeled, self-balancing scooter, on Good Morning America.
The Segway PT made its debut after months of hype and rampant press speculation during which it was known only by its code name, “Ginger,” or sometimes just “It.” Kamen’s reputation as a brilliant inventor and businessmen opened doors, and the cleverness of his design convinced backers they were onto something hot.
Amazon founder Jeff Bezos and legendary venture capitalist John Doerr were early and enthusiastic investors, and Apple co-founder Steve Jobs even predicted that cities would be redesigned around the device and that it would be even more significant than the personal computer.
And then the cover came off, and the Segway was revealed to be... a scooter.

Wednesday, December 2, 2009 at 6:30PM PETA is one of the most controversial activist groups operating today. The group's contentious media campaigns, undercover operations, infamous advertising, and high profile demonstrations have made them perhaps the most notorious--and most polarizing--nonprofit organization there is. But are they terrorists? According to the US Department of Agriculture, they are now.
And right when PETA was about to be able to call it quits, too. The USDA has just released a new security profile form (pdf), which it distributes to animal experimentation facilities. The form reveals that PETA has been classified as a terrorist threat by the US government--potentially opening up its members to prosecution as terrorists.
