Radio telescopes capture best-ever snapshot of black hole jets An international team, including NASA-funded researchers, using radio telescopes located throughout the Southern Hemisphere has produced the most detailed image of particle jets erupting from a supermassive black hole in a nearby galaxy. "These jets arise as infalling matter approaches the black hole, but we don't yet know the details of how they form and maintain themselves," said Cornelia Mueller, the study's lead author and a doctoral student at the University of Erlangen-Nuremberg in Germany. The new image shows a region less than 4.2 light-years across -- less than the distance between our sun and the nearest star. Radio-emitting features as small as 15 light-days can be seen, making this the highest-resolution view of galactic jets ever made.

The First Few Minutes After Death A three-year study will explore the nature of death and consciousness Dr. Sam Parnia: "When you study mind and brain, you see that, although in many circumstances this practical model we have developed -- mind and brain are the same thing -- is fine, when you go to an extreme environment like during a cardiac arrest…they don't seem to apply anymore," says Parnia.

Fear the Beard: Everything You Ever Wanted to Know About Facial Hair (Infographic) Ever wonder if growing facial hair has a purpose beyond making it easier to play “Spot the Hipster” at trendy urban coffee houses? Apparently it does. While modern may might grow a beard to intimidate opposing batters, prehistoric men grew beards to keep warm, intimidate enemies and protect their faces from punches. Plus, ancient civilizations saw beards as a sign of honor, and women today — while admitting they find bearded men to be 67% as attractive as clean shaven men — consider guys with full facial hair to be more respected, powerful and of higher status. Barcode Yourself by Scott Blake Barcode Yourself is a complete, interactive experience in the series of barcode art, created using the personalized data of participants. Enter an individual's gender, weight, height, age and location, and the barcode is formed using real-world data. The individualized barcode can then be printed, mapped, scanned, even depicted on a t-shirt or coffee mug. Uber-geeks can even test out their barcodes on their next grocery run. It is in scanning a barcode that the project reveals its humor, like a banner that reads: Disclaimer!
Video Courses on Academic Earth Astronomers use tools like telescopes, cameras and spectrographs to study interactions between materials and energy within the universe. These scientists learn about galaxies, solar systems, planets and stars through careful observation and measurement recording. Astronomers also refer to natural sciences and mathematics to form and test theories. An integral part of a student’s astronomy experience is the quality of equipment and facilities they have access to. What is an Operating System Not all computers have operating systems. The computer that controls the microwave oven in your kitchen, for example, doesn't need an operating system. It has one set of tasks to perform, very straightforward input to expect (a numbered keypad and a few pre-set buttons) and simple, never-changing hardware to control. For a computer like this, an operating system would be unnecessary baggage, driving up the development and manufacturing costs significantly and adding complexity where none is required.
ACR & Balancing Retouching Webinar "Straight out of the camera, I've got this ordinary digital capture without enough tonal contrast in my model, flat and dull colors, and overall no "wow" factor. The image just doesn't pop. I can't post it as is, it needs to be post-processed…" If I had a nickel for every time I'd said or read something like that.
