They Know Your Every Thought!
Life Sciences - Medicine
Jan 02, 2009 at 07:59 PM

New Scientist has reported on a technology is being developed that may eventually allow your dreams and thoughts to be recorded and played back.

resultsYukiyasu Kamitani at ATR Computational Neuroscience Laboratories in Kyoto, Japan is leading the development team. They use a scanner to record brain activity when a subject is shown a group of 10x10 dots. Software "learns" to associate different patterns of brain activity with different patterns.

In a paper published in the journal Neuron, Kamitani showed that by pooling the results from various volunteers it is possible to recreate the word "neuron" from the scans.

Kamitani says that higher quality images should be possible with improved brain scanners. He wants to find out if it is possible to create record images people are imagining rather than seeing.

It may eventually be possible to record dreams. This leads to all kinds of privacy and legal questions. Could such technology be used to eavesdrop on a person’s thoughts? Could your dreams become cause for divorce?

Big Brother is not only watching you, he is reading your mind ad well.

Brian Wang over at Next Big Future has edited Carnival of Space 84. Lots of interesting stuff as ever.

If you found my post "Does Obama Want the Moon?" interesting, you will find some posts looking at the future of US space policy on this carnival.

Sky Ready for 3DTV Broadcasting
Technology - Television
Dec 19, 2008 at 08:00 AM

Satellite Broadcaster BSkyB, has demonstrated its new three-dimensional television (3DTV) system. The new system can broadcast 3DTV into homes using existing high-definition TV infrastructure.

Three-dimensional viewing is on a roll. Games systems are pushing the development of 3D screens. Nvidia's newer graphics cards use Stereo Gaming technology to enhance some of the most popular PC games.

The magic specs were back in the cinema this year with 'Journey to the Centre of the Earth' and 'Beowulf' both doing well at the box office. Other 3D movies such as 'Toys Story 3' and 'Ice Age – Dawn of the Dinosaurs' are due out in 2009.

According to BSkyB 3DTV is not far behind. Sky engineers have so far broadcast sporting events and the TV show Gladiators.

The BSkyB system requires viewers to wear special 3D glasses. Technology allowing viewing of 3D shows without special glasses will be cheap enough to use in the home in five to ten years time.

The system also requires a special television set capable of converting the dual pictures sent over the satellite link, into a 3D display. Mitsubishi launched a 73-inch 3D television receiver in June 2008. Other companies are expected to follow in 2009 with prices in the £2,000 range (US$3000).

NASA and the US DOD’s Evaluation of LASIK
Life Sciences - Medicine
Dec 18, 2008 at 08:34 AM

LASIK is an acronym of Laser-ASsisted In situ Keratomileusis. It is a type of refractive laser eye surgery for correcting myopia, hyperopia, and astigmatism.

LASIK technology

The standard LASIK procedure involves three steps.

  • Creation of a flap of corneal tissue, which is then folded back.
  • Remodelling of the cornea underneath the flap with the laser.
  • Repositioning of the flap.

A modern form LASIK, known as the iLASIK™ Procedure, uses two lasers instead of one. The replacement of the hand held microkeratome blade used in older forms of LASIK increases safety. The iLASIK™ Procedure has the following steps

  • Wave-front technology maps the unique characteristics of the individual’s eyes.
  • Ultrafast, computer-guided laser creates a corneal flap.
  • The wave-front mapping data guides a second laser for vision correction.
  • Repositioning of the flap.

The combination of these advanced laser technologies creates a custom-fit procedure clinically proven to provide excellent safety and visual results.

LASIK information

In an evaluation of modern LASIK was carried out by the US military, of 100 personnel 95 achieved 20/20 vision or better. All of the naval aviators involved would recommend the procedure to their comrades.

Both NASA and the U.S. Department of Defence (DOD) now use the technology to improve the performance of mission-critical personnel. Steven Schallhorn, M.D., is a retired U.S. Navy captain and leader of clinical research and studies done for the DOD regarding the use of LASIK. "The DOD and NASA have validated the fact that today’s LASIK exceeds all established standards of safety and effectiveness," says Schallhorn.

Does Obama Want the Moon?
Space Exploration - Plans and Policies

Reports of a public row between NASA administrator Mike Griffin and Lori Garver, a member of Barack Obama’s transition team, has reignited speculation on the future of NASA’s manned Moon mission.

The Orlando Sentinel reported a "heated" 40-minute conversation between a "red-faced" Griffin and Garver at a book-publication party at NASA headquarters last week According to witnesses Griffin demanded to speak directly to Obama.

President Elect Obama has sent teams to every government agency in order to ensure smooth transition between administrations. Their job is to dig through budgets and plans to find anything that may cause problems for the incoming administration. The Bush White House has ordered full cooperation.

Griffin appears to consider this a personal insult. Witnesses to the "animated conversation" reported Garver as saying, "Mike, I don’t understand what the problem is. We are just trying to look under the hood."

"If you are looking under the hood, then you are calling me a liar," Griffin replied. "Because it means you don’t trust what I say is under the hood."

Griffon Worried

Griffin was appointed by President Bush four years ago to lead NASA in the efforts for a return Moon shot by 2020 and then on to Mars. He has overseen the selection of Constellation, with its NASA-designed Ares I rocket and Orion capsule for the job. Griffin would like to stay on under the new administration, "under the right circumstances."

Budgetary problems and technical issues with Constellation have been the subject of the transition team's scrutiny. They have asked NASA how much could be saved by cancelling the Area I rocket. They have also asked about accelerating the program. The cancellation question has obviously worried Griffin.

The Orlando Sentinel also reports Griffin is orchestrating a campaign to defend Constellation. It says Griffin is:

"...scripting NASA employees and civilian contractors on what they can tell the transition team and has warned aerospace executives not to criticize the agency’s moon program."

NASA's Chief of Strategic Communications, Chris Shank denied there was an argument or that Griffin is trying to keep information from the Garver's team. He denied that Griffin is seeking a meeting with Obama.

He did acknowledge that Griffin felt the team lack the expertise to assess some of the information they have been given. Griffin, an engineer, has said the Garver is "not qualified" to make decisions on NASA’s rocketry program.

Garver has refused to comment, but people close to her say she has confirmed "unpleasant" exchanges with Griffin and other NASA officials. Garver recently told a Washington meeting of aerospace representatives, "there will be change" to NASA policy. She hinted that there would be a new administrator soon.

Obama's Shifting Position

The situation is exasperated by Barack Obama’s lukewarm support for the Moon shot during his election campaign. His position early in the primaries was to see more NASA spending on education at the expense of the Moon landings. He shifted several times during the campaign.

Obama only came out firmly in support of the new Moon shot when if became obvious that the loss of jobs in important battleground states such as Florida could derail his bid for the Presidency.

However, these pledges were made when the federal budgetary considerations was very different from those today. It would not be hard to find justification for cutting NASA's budget.
