The Week In Numbers: Sneaky Penguin Cars, Bullets For 3-D Printed Guns, And The Birth Of A Planetary System
Plus a taste of crunchy crickets
Solar system comparison
450: Distance, in light years, star HL Tau is from Earth. HL Tau, also known as HL Tauri, was photographed in the first high-resolution image of a planetary system’s birth.
0.314: Caliber of bullets machinist Michael Crumling designed to be specially used in 3-D printed guns.

891: People traced and monitored for Ebola symptoms for 21 days in Nigeria in order to halt the spread of the deadly disease in that country. Nigeria was declared Ebola-free (for now) on October 20.
54: Test flights Virgin Galactic SpaceShipTwo successfully completed before disaster struck on October 31. One pilot died and the other severely wounded when the spaceship disintegrated over the Mojave dessert during a test flight.

250: Ballots needed to be counted per state to know whether or not an election was rigged.
$912 million: Cost of the world’s newest and most powerful particle accelerator set to start working on Long Island by the end of 2014.
Two Accelerators, Long Island, New York, July 2013
150: People who suggested the winning name of Agilkia for Rosetta’s comet landing site. It only seems fitting because Rosetta’s lander, Philae, and Agilkia are both named after Egyptian islands in the Nile River.
8: Vibrating motors built into a high-tech harness that allows for dogs and humans to communicate via computer. Dogs can be trained to correlate specific commands with unique combinations of vibrations.

0.11: Inches the sea level in Boston is rising by each year, which puts the coastal city in a particularly precarious position with large storms like Hurricane Sandy. Boston is considering implementing a Venice-like canal system to deal with rising waters.
11: Daring Popular Science staffers who taste-tested cricket protein bars.
Crunchy, yet satisfying?
3: Penguins per second that a scientist-controlled penguin car can scan. The car disguised as a baby penguin was invented so scientists can infiltrate penguin colonies with minimal stress to the tagged animals when collecting information with a remote-controlled RFID reader.
