Operation Code Name 'Vanished Star'
The vast majority of stars end their lives through supernova explosions while others, more massive, are thought unable to produce such explosions simply because they implode and collapse under their own weight only to produce a black hole. Since these particular types of stellar death don't generate brilliant emissions in the electromagnetic spectrum, none has ever been witnessed. This is about to change with the initiation of a new study which has the sole purpose of watching for red giant...

Found Footage: Understanding technology's past
Author: Steven Sande
Filed under: Retro Mac, Found Footage, Apple History  When I think about a computer, I usually don't think about a 5-ton assembly of brass gears, cams, and steel rods. Yet in 1847 - 1849, Charles Babbage first created his design for the Difference Engine No. 2, a large mechanical computer that used these non-electronic components.Nathan Myrhvold, former Chief Technical Officer of Microsoft, commissioned the building of a Difference Engine No. 2 based on Babbage's design. It's on display at the Computer History Museum in Mountain View, CA, and will soon grace the living room of Myrhvold's home. What does this have to do with Apple? In this MarketWatch video, it's mentioned that Babbage had problems getting funding for a device that was considered to be ahead of its time. It kind of reminds me of Apple's Newton MessagePad. It was the progenitor of all PDAs and smartphones, but failed in the marketplace because of its price and the fact that few people understood what it was good for.The video also highlights Daniel Janisch, PowerBook Guy, who upgrades and sells antique PowerBooks (8-year old "Pismo" PowerBooks, for example). You can run Tiger on the Pismos, but they're often abandoned for the new kids on the block.Thanks to Jomo for the link!Read | Permalink | Email this | Comments

Mobile phones alter brain behavior?
Author: David Pescovitz
New research shows that the electromagnetic signals emanating from mobile phones can alter your brainwaves. Indeed, the latest studies suggest that mobile phone transmissions can even affect behavior. In one study, scientists from the Swinburne University of Technology monitored the brainwaves of folks with Nokia phones, er, strapped to their heads. They noticed that the cell phone transmissions boosted alpha waves. In a separate experiment, researchers from the Loughborough University Sleep Research Centre observed that sleep-deprived subjects with phones on their heads showed a dampening of delta waves that are markers of sleep. For hours after the phones were turned off, the test subjects exhibited difficulty falling asleep. From Scientific American:
Although this research shows that cell phone transmissions can affect a person's brainwaves with persistent effects on behavior, (Loughborough University's James) Horne does not feel there is any need for concern that cell phones are damaging. The arousal effects the researchers measured are equivalent to about half a cup of coffee, and many other factors in a person's surroundings will affect a night's sleep as much or more than cell phone transmissions.
"The significance of the research," he explained, is that although the cell phone power is low, "electromagnetic radiation can nevertheless have an effect on mental behavior when transmitting at the proper frequency." He finds this fact especially remarkable when considering that everyone is surrounded by electromagnetic clutter radiating from all kinds of electronic devices in our modern world. Cell phones in talk mode seem to be particularly well-tuned to frequencies that affect brainwave activity. "The results show sensitivity to low-level radiation to a subtle degree. These findings open the door by a crack for more research to follow. One only wonders if with different doses, durations, or other devices, would there be greater effects?"
