    Thomas J. Johnson, the creator of the modern Schmidt-Cassegrain telescope and the founder of Celestron, died early this morning (March 13, 2012), according to Celestron president and CEO Joe Lupica. Johnson was 89. He ranked among the most important figures shaping the last half century of amateur astronomy.

Why some genes are silenced: Researchers find clue as to how notes are played on the 'g... - 0 views

  •  
    ScienceDaily (May 13, 2011) - Japanese and U.S. scientists in the young field of epigenetics have reported a rationale as to how specific genes are silenced and others are not. Because this effect can be reversed, it may be possible to devise therapies for cancer and other diseases using this information.

Laser, electric fields combined for new 'lab-on-chip' technologies | KurzweilAI - 0 views

  •  
    Researchers from Purdue University and colleagues are developing new technologies that combine a laser and electric fields to manipulate fluids and tiny particles such as bacteria, viruses, and DNA molecules for a wide range of potential applications, including medical diagnostics, testing food and water, crime-scene forensics, and pharmaceutical manufacturing.. This "hybrid optoelectric manipulation in microfluidics" technology could allow for innovative sensors and analytical devices for "lab-on-a-chip" applications, or miniature instruments that perform measurements normally requiring large laboratory equipment, the researchers said. The technology works by first using a red laser to position a droplet on a platform specially fabricated at Purdue. Next, a highly focused infrared laser is used to heat the droplets, and then electric fields cause the heated liquid to circulate in a "microfluidic vortex." This vortex is used to isolate specific types of particles in the circulating liquid, like a micro centrifuge. Particle concentrations replicate the size, location and shape of the infrared laser pattern. The technology can also be used in nanomanufacturing because it shows promise for the assembly of suspended particles (colloids), the researchers said. Ref.: Steven T. Wereley, et al., Hybrid opto-electric manipulation in microfluidics-opportunities and challenges, Lab on a Chip, 2011; 11 (13): 2135 [DOI: 10.1039/C1LC20208A]

Face Recognition Moves From Sci-Fi to Social Media - NYTimes.com - 0 views

    And this technology is spreading. Immersive Labs, a company in Manhattan, has developed software for digital billboards using cameras to gauge the age range, sex and attention level of a passer-by. The smart signs, scheduled to roll out this month in Los Angeles, San Francisco and New York, deliver ads based on consumers' demographics. In other words, the system is smart enough to display, say, a Gillette ad to a male passer-by rather than an ad for Tampax.
