In 1860, the man in the center of this photo, Albert Myer, became the first-ever signal officer of the U.S. Army. (He's seen here some months later during the Peninsula campaign of the Civil War.) While the government liked Myer's ideas on signaling well enough to establish the U.S. Army Signal Corps at that time, the early years of the undertaking faced any number of challenges--ungainly technology, bureaucratic infighting, lack of funding and staffing. But the seed was planted in those early days, and the Signal Corps has now been around for 150 years (making this year the sesquicentennial), at the forefront of technologies from the telegraph to radio, radar, and satellite communications.

Spirit's right-front wheel, visible in this October 2009 image, has not worked since 2006. It is the least-stuck of the rover's six wheels at the current location, called "Troy." NASA/JPL-Caltech 
This new copepod, Ceratonotus steiningeri, was first discovered 5,400 metres deep in the Angola Basin in 2006. It was also collected in the southeastern Atlantic, as well as some 13,000 kilometres away in the central Pacific Ocean. Scientists are puzzled about how it achieved such widespread distribution and avoided detection for so long. Credit: Jan Michels
Each time a cell divides, the protective "caps" at the tip of chromosomes (red and green dots) erode a little bit further. As telomeres wear down, their DNA undergoes massive changes in the way it is packaged. These changes likely trigger what we call "aging."

To celebrate the 50th Anniversary of the word “cyborg,” Tim Maly of Quiet Babylon is running a 50-post tumblr of quotations and articles about, well, cyborgs. The first post gives us the space-oriented (and rather wordy) origin of the term:
For the exogenously extended organizational complex functioning as an integrated homeostatic system unconsciously, we propose the term “cyborg”.
