New Earth-observing satellite launch by NASA

Delayed Earth-observing satellite to launch from California early Friday

After a five-year delay, an Earth-observing satellite will be launched to test new technologies aimed at improving weather forecasts and monitoring climate change.

The $1.5 billion NASA mission comes in a year of weather extremes from the Midwest tornado outbreak to the Southwest wildfires to hurricane-caused flooding in New England.

"We've already had 10 separate weather events, each inflicting at least $1 billion in damages," said Louis Uccellini of the National Oceanic and Atmospheric Administration.

The satellite will lift off before dawn Friday from Vandenberg Air Force Base, Calif., aboard a Delta 2 rocket that will boost it into an orbit some 500 miles high.

The space agency already has a fleet of satellites circling the Earth, taking measurements of the atmosphere, clouds and oceans. But many are aging and need replacement.

The latest -- about the size of a small school bus -- is more sophisticated. It carries five different types of instruments to collect environmental data, including four that never before have flown into space.

One of the satellite's main jobs is to test key technologies that will be used by next-generation satellites set to launch in a few years.

NOAA meteorologists plan to feed the observations into their weather models to better anticipate and track hurricanes, tornadoes and other extreme weather.

The information will "help us understand what tomorrow will bring," whether it's the next-day forecast or long-term climate change, said Andrew Carson, the mission's program executive at NASA headquarters.

The satellite is part of a bigger program with a troubled history. Originally envisioned as a joint civil-military weather satellite project, ballooning costs and schedule delays caused the White House last year to dissolve the partnership.

Under the restructuring, the Defense Department is building its own military satellites while NASA is developing a new generation of research satellites for NOAA. Friday's launch is considered the first step toward that goal.

The satellite was supposed to fly in 2006, but problems during the development of several instruments forced a delay. NASA invested about $895 million in the mission while NOAA and the Air Force contributed $677 million.

For the launch, NASA invited 20 of its Twitter followers to Vandenberg, where they will receive front-row seats to view the liftoff.

Once in orbit, the satellite, built by Ball Aerospace & Technologies Corp. in Boulder, Colo., will spend the next five years circling the Earth from pole to pole about a dozen times a day. Data will be transmitted to a ground station in Norway and routed to the United States via fiber optic cable. NASA will manage the mission for the first three months before turning it over to NOAA.

Twitter may influence the spread of disease

The northern hemisphere flu season will soon be here. If you get vaccinated and tweet to your followers follow you doctor's surgery - or are they the kind of people who have booked an appointment?

American scientists have extracted Twitter for tweets that short and influenza vaccination, and found that the results of the prevalence of vaccination in parallel. Now they want to know about Twitter correct posture reflects vaccination or help distribute them.

Marcel Salathe from Penn State University in University Park, Pennsylvania, 478,000 tweets referring to the flu collected in late 2009 when the vaccine for swine flu pandemic was available in the U.S.. A team of students categorized 10 percent of tweets as for, against or neutral on vaccination. Then these tweets used to design an automated screening test that the rest classified create.

Each tweet out information about the region it came from. The team found that in areas with lower vaccination rates tend to be more negative tweets about vaccination, and vice versa.

Such mapping could help to address health information campaigns, Salathe said. "If we know where people are very poorly informed, so we know what we must do better on the information."

Echo Chambers
Salathe also uses Twitter to a number of other health problems including obesity, social attitudes that may influence the distribution of the track.

Flu Tweets flowed "echo chambers", especially among people who agree with each other. Salathe now trying to find out if it's because people talk to people who think like them or think like people who speak them. He is developing new statistical tools to do this to tease Twitter data. "Preliminary analysis shows that it is very likely that the negative opinions of vaccination is contagious on online social networks," he says.

It would be bad news if the number of people who refuse to be vaccinated is rising. Twitter is a rich source of data to map these attitudes, Salathe said. Efforts to change the hearts and minds, might or might not work, "but if you do not know what your problem is that you never solve."

Turn anything (even your clothes) into a touchscreen

Want the convenience of a touch screen, without the hassle of removing your phone from your pocket? Researchers at Microsoft have you covered, with two new touch-interface that allows any surface into a touch screen or control the phone from a pocket.

OmniTouch combine a pico projector and a Kinect-like depth-sensing camera in a shoulder-mounted device that can project a multitouch interface on a wall, desk or even create your own hand. Users can define the size and location of their own interfaces, or have the system determine the best choice in the display.

Chris Harrison, who worked on the project, calling it a "mega Kinect hack" and an extension of his former unit, which can just work on the skin. While the prototype unit is quite bulky, the team says it could be possible for future versions of the size of a matchbox to be.

If you prefer not to project your screen so everyone can see, touch, pocket you can manage your phone while you are in your pants. The team created a prototype device with a grid of touch sensors that finger strokes can be detected using the drug and developed a specific lock gesture reorientates screen every time you use it - avoiding the need for the phone upside down to use interface.

They found that the screen was sensitive enough to existing contact Microsoft recognition software that makes it possible to send an SMS using one character at a time, or manage your playlists with a few strokes of your thighs. Both systems will be featured this week on User Interface Software and Technology conference in Santa Barbara, California.

Robot builds its own body from sprayable foam

If a sculpture coming to life, a new type of robot body parts using spray-on foam to do. Such a construction could one day be useful in situations where the exact type of robot is not needed is known in advance, as space exploration or investigation.

By Shai Revzen and his colleagues at the University of Pennsylvania Foambot consists of a mobile "mother ship" platform along with some simple common modules are driven flexing and bending. The platform has a built-in supply of chemical reagents and a nozzle, mixing with reagents to expand in tough urethane foam. First remote platform control modules on the floor and then spray foam to connect them into the desired shape.

Software then analyzes the information of active joints, and devises a plan to coordinate the resulting bone animation.

Revzen said the system would be useful for situations where the robots have to navigate the unforeseen obstacles. A snake-like body could be better for crawling rocks, which during a four-legged friend can be better in open terrain to traverse. Since Foam Bots can return to the mother ship to be changed, they can be used to treat a wide variety of tasks.

Grave-robbing robot could revive dead satellites

  Satellites at the end of their life, often performed in a "graveyard" orbit to make room for replacements. DARPA has now proposed a desecration robot that can stitch together parts of dead satellites to these new, avoiding the enormous costs associated with the launch of components in space.

DARPA's Phoenix program aims to re-purpose ground robotic systems, such as those used by surgeons to operate on patients remotely, so that a person on earth to satellites to separate and reuse expensive components such as antennas.

The program will also develop a new type of nano-satellite hitch a ride aboard a normal satellite launcher and throws it right when it reaches orbit. The grave-robber robot can scoop up these nano and add them to an old antenna on a new low-cost communication platform to create.

Plans are in place for a first test mission in 2015 with robotic harvesting components in an existing satellite retired and reconfigure them into a new purpose. But the grave-robber will not be able to go after an old satellite - the Outer Space Treaty means that any object sent into space will remain property of the country, to launch, although it was dumped in a graveyard orbit.

Action-packed video games help solve lazy eye

Unreal Tournament has been modded to treat amblyopia (Image: Epic Games)

It sounds like a teenager's dream: to play shoot-em-up video games, a prescription.

On the American Academy of the annual meeting of Ophthalmology in Orlando, Florida, reported a team led by Somen Ghosh of microsurgical Eye Clinic in Kolkata, India, the video game therapy to improve visual acuity 10 - to 18 - year-olds with amblyopia or "lazy eye ".
This comes hot on the heels of similar findings from a study of adults with the disease, published in PLoS Biology by a team led by Roger Li and Dennis Levi from the University of California, Berkeley. Even more impressive results can be on the horizon, such as video games are combined with another approach, known as "perceptual learning".

Amblyopia occurs when the neural connections from one eye to the brain do not develop normally. Over time, the brain reacts by ignoring the fuzzy input of these "weaker" eye.

The condition can be treated in childhood by patching the good eye and visual exercises for the poor to build neural connections - but dogma until recently was that nothing can happen after about 9 years.

The idea of ​​using video games came from the discovery that expert gamers have unusually strong visual skills. Subsequent studies have shown that action games can improve contrast sensitivity in people with normal vision.

Ghosh studies in children and teenagers with amblyopia who received standard treatment of the patch, glasses and visual exercises, with or without additional treatments. Although the group receiving only the basic treatment showed some improvement after one year - but they were also asked to first-person shooter or racing game to play every day, but noticeably better.

In adults, some of the best results in the treatment of amblyopia are not using the computer, but instead educated people to faint gray patterns known as Gabor patches to distinguish. In 2004 a group led by Uri Polat of Tel Aviv University in Israel that this perceptual learning resulted in twice the improvement in patients' contrast sensitivity.

But even Polat, who recently used a similar approach to the treatment of the natural decline in near vision that occurs with age, admits that the exercises are a little boring for teenagers.

So how about combining perceptual learning with gaming? Now being tested by Levi's lab, in collaboration with a team led by Daphne Bavelier of the University of Rochester in New York.

Researchers Gabor patches embedded in a modified version of the first-person shooter Unreal Tournament, where they are tested as a treatment for amblyopia.

"You have to shoot at the patches," Bavelier out. "If you do not turn them into nasty robots that are really hard to kill.

Kodak misfires with EasyShare Max

If you fancy technology becomes increasingly complex, cameras are probably no exception. You want something that is incredibly easy to use and offers tons of zoom. You want to rely on inspiration and creativity to good pictures - no technical know-how. Unfortunately this is not so "easy" as it sounds.

Kodak EasyShare Max, also known as Z990 ($ 200 - $ 330), is an update of last year's Z981, and stands out with some new features. Schneider Optics has a new lens assembly, which extends the zoom ratio of up to 30x. The sensor was also replaced with a back illuminated CMOS, a technology that provides low light and faster improvement.

We love the idea of ​​a single shot with a 30x zoom lens, but the EasyShare Max just does not fulfill his promise. Sloppy design means photography is difficult and frustrating. Slow processing means that the operating speed slows to a crawl, interruption of photo shoots and leaves users confused. The menu system is complicated and inefficient, exacerbate the problems already slow processor. To make matters worse, every time the camera's automatic features make a bad effort, and people think orange and no custom white balance setting color accuracy is terrible in the interior.

The combination of technology and ease of use, Kodak is trying to straddle both sides of the fence, but instead slipped and landed rather painfully on the business end of the pickets. Consumers are sure to be disappointed, especially with Kodak directly at the threshold of a winning strategy. The casual market is telling a simple camera with lots of zoom, but Kodak would be better off focusing on quality, stripping the advanced features, and none of the price. Instead, Kodak market their products as the easiest to use, and then delivered a camera that is lower than the competition in quality and usability. This is not simplistic, it is simply inferior.

Kodak should take a look at the audience, and begin to connect to design dedicated to that demographic. As it is currently, Kodak EasyShare, Max is in an uncomfortable limbo land not suitable for beginners and experienced shooters alike.

TripAdvisor mobile guides smartly steer tourists

If you want some of the great cities of the world tour without having to hire a guide or drag a thick manual, TripAdvisor's new Mobile City Guides for Android smartphones and tablets now offers a delicious alternative.

You can use the free city guides download one at a time from the Android Market and discover the Self-Guided tours Free in Beijing, the best restaurants in Chicago, an interactive map that shows the most remarkable sights in Boston, and an overview of culture and architecture in San Francisco.

TripAdvisor traveler wrote on her bones hotel reviews. So each guide combines advice from TripAdvisor travelers with many hotel and restaurant reviews and ratings obtained from the global websites TripAdvisor.

There are apps in 20 cities. Each guide uses your mobile device features GPS and compass to find your location and direct you to your desired attraction.

All wizards to work offline, even without Wi-Fi, so you can avoid wireless roaming charges when traveling.

But to get guides about updates or access to the latest consumer written hotel and restaurant reviews from TripAdvisor, you need a wireless connection to type.

This TripAdvisor Mobile City Guides are comprehensive and very tourist-friendly.

The New York City guide, for example, offers 14 self-guided tours. The range of one to three hours Brooklyn Bridge walk into a half-day trip and a bakery Cupcake Crawl 10-stop Wall Street and Financial District walk.

One major gripe with the first Mobile City Guides is that they are a little predictable and light on risk appetite.

Some of New York City Self-guided tours, for example, recommend collapsible buggies for small children or carry disinfectant wipes or tote on Cupcake Crawl.

Wall Street and Financial District Tour takes place in the World Trade Center site and Trinity Church. It does not mention the nearby occupied Wall Street protests have been a quirky tourist attraction.

And if New York Macy guidance states that one of the top 100 tourist attractions, but not in detail why or give any anecdotal information - other than what people say on TripAdvisor - the place Herald Square store.

You would what city guide information from Lonely Planet, a competitive New York City Guide app for 99 cents offer to learn that Macy is time consuming "creaky old wooden elevators at the Broadway side is a must-do experience NYC."

The Point Me A feature of the Mobile City Guide TripAdvisor apps are cool. If your French is rusty and you do not want to ask for directions in Paris, press the arrow to point me to learn the distance to your destination. Of smartphone compass will guide you.

On the negative side, there are complaints from users who are online TripAdvisor city guide apps are memory pigs that SAP a smartphone memory. But New York City Guide 14.88 MB does not have this problem.

A closer look at the first Mobile City Guides:

• Overview. Free mobile apps on Android devices to 20 global cities combines tips and information from TripAdvisor travelers with ratings and reviews. Including restaurants, walks, attractions, hotels, neighborhoods, history, culture, architecture, weather and transport information.

• Pros. Comprehensive, fast, combining advice on TripAdvisor reviews. Works offline to avoid roaming charges. Interactive map and immediately gathers the best tours, attractions, restaurants on a single card, and you can toggle between a list view and map view. GPS identifies attractions nearby, and me and compass point lead there. Searches can be filtered at the restaurant, price range, cuisine and attractions.

• Cons. Do you feel like a typical tourist with little treasures and hidden spots. Counseling is mostly common sense, lack of insight. Available on Android devices. Some users refer smartphone memory overload.

• Takeaway. Impressive and easy to use, but predictable. A convenient way to travel as tourists. If you are looking for a one-of-a-kind experience, you should use a social travel site that Gogobot or Wanderfly or contact a site-local (NileGuide Ask a Nomad, Triptrotting).
