 AWA: When Machines Rule July 24 2008
from Are We Alone? - SETI Science and Skepticism
July 24, 2008
REPEAT Every year, computing machines become more powerful, a fact that hasn't escaped the notice of anyone who occupies an office. Many experts now agree that within a few decades, your laptop will be smarter than you are. Not only that, but your computer will be in touch with its byte-busting brethren. When that happens, the machines will "wake up." But what takes place next? Can we stop the machines from turning us into protoplasmic peons in a world in which they are the top intellectual dogs? Seth and Molly go to the Singularity Summit in San Francisco, and talk to some far-sighted humans who are preparing for the next generation of brainiacs - and they won't be your offspring! Guests: Eliezer Yudkowsky - Research fellow and co-founder of the Singularity Institute for Artificial Intelligence Everett Sherwood - Former research member at Motorola Labs Brad Templeton - Board member, Foresight Nanotech Institute, and Chair, Electronic Frontier Foundation Charles Harper - Senior Vice President, John Templeton Foundation

 Infrared Photography - Cheap and Easy
from popular posts - blip.tv (beta)
July 23, 2008
On my website are some instructions for converting a web cam to for cheap, easy infrared photography. Basically, all digital cameras are capable of detecting infrared radiation just outside of the visible spectrum. That is to say light with a longer wavelength than the red end of the spectrum. With some slight modification we can filter out the visible light and let through the infrared light. This will not allow you to do thermal imaging, which is done in the far infra red.The web cam I used was designed for use in low light. It includes six IR LEDs. More importantly, since it was designed to work with IR LEDs it lacks the IR filter that most digital cameras include. The IR filter found in digital cameras helps keep colors more consistent at all light levels. Consequently it blocks most of the light we're interested in for this project. A quick Google Search will reveal several places that sell the exact same camera I used (some for under $10).

 TERRA 438 PREVIEW: Trouble in the Tropics: Invasive Lionfish
from TERRA: The Nature of Our World
July 23, 2008
The invasive lionfish--venomous and voracious--has reached the tropical western Atlantic, where its reproductive rate is soaring. Invasive species expert, Lad Akins, of the Reef Environmental Education Foundation; along with College of the Bahamas marine science intern, Everton Joseph; and specimen collector for the Bermuda Aquarium, Chris Flook, team up in the waters of the Bahamas, where they dive, collect, tag and dissect, to better understand the invader in its new home. They'll run key field experiments, to identify potential controls, and assess the likely impacts of the invasion, on fragile reef ecosystems and ocean-based economies.

Credits:A film by Semiconductor: Ruth Jarman & Joe GerhardtPhotographed and Recorded at the Space Sciences Laboratory UC BerkeleySpace Physicists in order of appearance: Janet Luhmann, Bill Abbett, David Brain, Stephen MendeVLF Radio Recordings Stephen P McGreevySynopses:Natural magnetic fields are revealed as chaotic, ever-changing geometries.Scientists from NASA's Space Sciences Laboratory excitedly describe their discoveries.Natural magnetic fields are revealed as chaotic, ever-changing geometries as scientists from NASA's Space Sciences Laboratory excitedly describe their discoveries.The secret lives of invisible magnetic fields are revealed as chaotic, ever-changing geometries. All action takes place around NASA's Space Sciences Laboratory, UC Berkeley, to recordings of space scientists describing their discoveries. Actual VLF audio recordings control the evolution of the fields as they delve into our inaudible surroundings, revealing recurrent 'whistlers' produced by fleeting electrons. Are we observing a series of scientific experiments, the universe in flux, or a documentary of a fictional world?

AWA: Genes That Fit July 21 2008
from Are We Alone? - SETI Science and Skepticism
July 21, 2008
Remember Mr. Potato Head? You changed his look by snapping in plastic mustaches, googly eyes and feet. Now imagine doing the same with a living cell: inserting the genes you want to create the organism you want. Welcome to the world of synthetic biology. It has potential to create new bio-fuels and life-saving drugs. It also ushers in a host of ethical and safety concerns. We examine both when we discuss this emerging science of mix and match genes. Plus, does doing an end run around Mother Nature challenge the essence of life itself? Guests: Jay Keasling - professor of chemical engineering and biological engineering at UC Berkeley and founder of Amyris Biotechnologies Jonathan Eisen - biologist at UC Davis Jim Thomas - researcher at ETC group in Ottawa, Canada Ed Regis - science writer and author of What Is Life: Investigating the Nature of Life in the Age of Synthetic Biology Michael Dosmann - curator of Living Collections at the Arnold Arboretum of Harvard University

 Ep. 98: Quasars
from Astronomy Cast
July 20, 2008
Last week we talked about galaxies in general, and hinted at the most violent and energetic ones out there: active galaxies. Quasars have been a mystery for half a century; what kind of object could throw out more radiation than an entire galaxy? A black hole, it turns out, with the mass of hundreds of millions of suns performs this feat. Let's trace back the history of quasars, how they were first discovered and puzzled astronomers for so long. And let's look at what we know today.

 MIT Physics Demo -- Exploding Wire
from "video" via Josh in Google Reader
July 18, 2008
A 100 uF oil-filled capacitor is charged to 3 KV. This takes approximately 15 minutes to charge, creating a charge on the capacitor that could be lethal. The capacitor is then discharged through a 12" length of 30 gauge bare iron wire.When the high voltage current flows through though high resistance wire, the bonds between iron molecules are shattered, resulting in a loud bang, a shower of sparks, and a cascade of wispy filaments floating through the air.Not all of the charge on the capacitor is disharged through the wire, so a shorting bar must be used to release the remaining charge.
