Video: Airborne laser test | The Daily Planet
Boeing has released videos of tests using the Advanced Tactical Laser, mounted on an airborne C-130H Hercules transport, to burn a hole in the hood of a truck. Embedding the video doesn't work so you'll have to visit the site.
Jetpacks Go Mainstream
May. 9th, 2009 08:59 amJetpacks Go Mainstream
The Martin Jetpack is capable of 30 minutes of sustained flight at up to 60 miles per hours with a ceiling of 8,000 feet. Comes with built-in parachute.
Fake feathers could take the drag out of flights - tech - 13 April 2009 - New Scientist
A University of Genoa researcher believes that adding artificial feathers to flight surfaces could reduce drag and, by extension, increase fuel efficiency. He tested the concept using a simulated wind tunnel and found that adding small, stiff bristles reduced the drag of a cylinder by about 15%. Future research would focus on demonstrating this with real systems.

Why do people have sex? Researchers explore 237 reasons - Many scientists assume people have sex for simple and straightforward reasons such as to experience sexual pleasure or to reproduce, but new research at The University of Texas at Austin reveals hundreds of varied and complex motivations that range from the spiritual to the vengeful. |
Scientists grow insulin in tobacco plants - U.S. researchers have discovered insulin grown in plants can resolve diabetes in mice -- a finding holding promise for humans afflicted with the disease. |
Fish eyes could hold clue to repairing damaged retinas in humans - A special type of cell found in the eye has been found to be very important in regenerating the retina in zebrafish and restoring vision even after extensive damage. Now, a UK team of scientists believe they may be able to use these cells – known as Müller glial cells – to regenerate damaged retina in humans, according to a study published this month in the journal Stem Cells. |

Unique Material May Allow Capacitors to Store More Energy - Imagine an electric car with the same acceleration capability as a gas-powered sports car, or ultrafast rechargeable "batteries" that can be recharged a thousand times more than existing conventional batteries. According to physicists at North Carolina State University, all of these things are possible, thanks to their research on a polymer - or plastic material - that when used as a dielectric in capacitors may allow the capacitors to store up to seven times more energy than those currently in use. |
Prevent smoking to reduce risk of erectile dysfunction - Men who smoke cigarettes run an increased risk of experiencing erectile dysfunction, and the more cigarettes smoked, the greater the risk, according to a study by Tulane University researchers published in the American Journal of Epidemiology. |
Obese girls less likely to attend college - Obese girls are half as likely to attend college as non-obese girls, according to a new study from The University of Texas at Austin. |
Robots Clear Waterways of Deadly Mines - As it slowly moves in the shallow water along a beach, the robot splashes its fins like a small child playing in the surf. But the prototype device has a serious mission: destroying mines that could kill Marines and Navy SEALs as they come on shore. Such technology is considered the future of underwater bomb detection. |
More fish oil, less vegetable oil, better for your health - Scientists have provided new evidence that using more fish oil than vegetable oil in the diet decreases the formation of chemicals called prostanoids, which, when produced in excess, increase inflammation in various tissues and organs. The results, by William L. Smith, Professor and Chair of Biological Chemistry at the University of Michigan, Ann Arbor, and colleagues, may help in designing new anti-inflammatory drugs with fewer side effects than the ones currently available. |

Nanotubes strengthen artificial muscles - BEST known as the ultra-strong material that might one day form the cables of a "space elevator" capable of raising people into Earth orbit, carbon nanotubes also have a springy side. The discovery that nanotubes keep bouncing back after being compressed repeatedly means this exotic form of carbon may be just the thing to give artificial muscles some extra strength |

Exfoliation produces lighter, cheaper solar cells - An ultra-thin solar cell that could provide a cheaper, lighter alternative to existing devices has been created by researchers in the US. James Zahler from Aonex Technologies, together with colleagues from Harry Atwater's group at the California Institute of Technology and researchers at EMCORE PhotoVoltaics made the device by replacing the relatively thick semiconductor substrate normally used in solar cells with a thin "wafer-bonded" substrate. This means the new device is considerable cheaper and lighter than conventional solar cells. |

Genetic variation may lower HIV load by 90% - A small genetic mutation in the section of human DNA that codes for immune proteins appears able to reduce the amount of HIV in the body by an average of 90%, new research suggests. Scientists say the finding points to new ways in which vaccines might one day help boost immune protection against the virus |

Moon jobs will tax mental health of workers - According to Chester Spell, an associate professor of management at the Rutgers School of Business—Camden, the lunar settlements of tomorrow – or, for that matter, the space stations of today – carry long-term implications for the mental health of employees working in isolation for extended periods. Depression and anxiety will reach new levels among those employees, creating mental and cardiovascular health problems as well as a sharp decline in productivity. |
DIY anti-satellite system - Satellite tracking software freely available on the Internet and some textbook physics could be used by any organization that can get hold of an intermediate range rocket to mount an unsophisticated attack on military or civilian satellites. |

Because I haven't posted in a while
Jun. 21st, 2007 01:51 pmI'm grinding out papers so I have no been in the mood to write summaries of tech stuff. I expect this to continue for a month or so because I'm currently in thesis-writing mode with hopes of finishing the draft before the end of July.
Meanwhile, I'm simply posting the links of things that caught my attention. There's quite a backlog, but I'll keep the list down to no more than 10 per post.

May. 7th, 2007 01:37 pmSource: New Scientist Boeing has suggested a way to increase the accuracy of weather forecasts: equip commercial and military aircraft with weather radar and have them collect the data while going about their usual business. The constantly-updated data would then be used to improve simulations on which forecasts are based. |
Source: New Scientist The US House of Representatives have recently passed the Genetic Information Nondiscrimination Act which makes it illegal for a person to lose their job or be denied insurance because they have the genetic predisposition for a particular illness. All that remains is for the President to sign it into law, a step that many are confident will take place. The only question in my mind is: does this deal with the possibility of an insurance company effectively denying coverage by making the premiums astronomical? |

Bonus fun fact from Improbable Research: The penis of a mallard duck can stretch 18 centimetres, and that of the Argentine lake duck can be as long as 42.5 centimetres. A researcher is building a transparent female duck so that she can see exactly what happens during copulation. If there are pictures or video, I don't want to see them.
