Apple’s “iPad” Tablet: It’s Here, It’s Cool, and It’s Slightly Cheaper Than Expected

submit to reddit

It has been one of the world’s worst kept secrets, but that hasn’t make the waiting any easier. Now, after years of whispers, rumors, speculation, and leaks, people can finally gawk at Apple’s latest offering–a new device the company refers to as the iPad. The thin and elegant tablet device was officially unveiled today by Apple CEO Steve Jobs in San Fransisco. The iPad “is so much more intimate than a laptop, and it’s so much more capable than a smartphone with its gorgeous screen,” Mr. Jobs crowed. “It’s phenomenal to hold the Internet in your hands” [The New York Times].

So what exactly is this tablet? The iPad, it seems, looks and acts a lot like a giant iPhone or iPod Touch. You can get your apps, play your games, store your pictures, watch your videos, and browse the Internet–but on a bigger screen and in higher definition. One addition to the tablet is that now you can read books online with Apple’s new iBooks.

At the launch, Jobs described the iPad as featuring a 9.7-inch, full capacitive multi-touch IPS display that weighs 1.5 pounds and measures just half an inch. “Thinner and lighter than any netbook,” according to Jobs [PCMag]. There’s also an on-screen keyboard for you to jab at. The tablet’s starting price is $499 for a 16 gigabyte device and goes up to $699 for the 64 GB version. If you throw in an extra $130, you’ll get 3G capability. Apple linked up with AT&T for its two 3G data plans: You can choose between paying $14.99 a month for 250 megabytes (which you could burn through pretty quickly by downloading multimedia) or $29.99 for unlimited data. In both cases, you don’t need a contract. All models feature built-in Wi-Fi, Bluetooth, an accelerometer, speaker, and microphone. It is expected to start shipping in March.

Myopia Mania: Americans More Nearsighted Than Ever

submit to reddit

eye220A new study comparing Americans’ vision today to what it was like nearly 40 years ago says that our nation’s eyesight is getting worse as myopia, or nearsightedness, continues to become more prevalent. The study, led by Susan Vitale, appears in the Archives of Ophthalmology.

Vitale and colleagues used data from the National Health and Nutrition Examination Survey (NHANES) to compare the percentage of black and white Americans aged 12 to 54 with myopia in 1971-1972 and 1999-2004 [Reuters]. In the early 1970s only a quarter of people were nearsighted, but by the study’s 1999 to 2004 window that number had shot up to 42 percent.

Is Google the Guardian Angel of Rainforests?

submit to reddit

deforestation-sat-webGoogle.org, the non-profit division of the search engine giant Google, wants to help scientists monitor deforestation by harnessing the power of its popular Google Earth and Maps applications. Its new “high-performance satellite imagery-processing engine” can process terabytes of information on thousands of Google servers while giving access to the results online. The platform, which was demonstrated on Thursday at the International Climate Change Conference in Copenhagen, would allow anyone using the tool to monitor whether or not trees were being chopped down in a given forest. It analyzes satellite images to show forest changes over a given time period [CNET].

The announcement comes at a time when delegates from around the world are attempting to negotiate a treaty to limit greenhouse gas emissions. Google debuted their new program at Copenhagen because they are hoping that their software could help countries conform to the REDD (Reducing Emissions from Deforestation and Forest Degradation in Developing Countries) program proposed by the United Nations, in which industrialized nations would pay developing nations to keep their forests standing.

Have You Consumed Your 34 Gigabytes of Information Today?

submit to reddit

stackofbooks220There’s nothing like a flashy statistic to get some attention, and scientists at the University of California, San Diego did just that by calculating the total amount of data consumed in the United States in 2008. The final tally? About 3.6 zettabytes (or 3.6 billion terabytes). That number works out to about 34 gigabytes per American per day. Put on paper, [the 3.6-zettabyte total] would be equal to 7-foot stacks of thick paperback novels placed side-by-side across the entire United States, including Alaska, said Roger Bohn, the study’s author and director of the university’s Global Information Industry Center [San Diego Union-Tribune].

Since the researchers excluded things people read for their work from the study, computers are only third in the total amount of time spent per information source. Most of this time is spent in front of screens watching TV-related content, averaging nearly five hours of daily consumption. Second is radio, which the average American listens to for about 2.2 hours a day [The New York Times]. Even without work hours, the researchers say, Americans log 1.3 trillion hours of information-gathering in a year, be it from print, online, TV, radio, or other sources.

Help a Needy Astronomer—Play the “Cosmic Slot Machine”

submit to reddit

galactic-mergersAstronomers want you… to help them match pictures of cosmic collisions, which are known as “galactic mergers.” Studying these mergers could explain why the universe has the mix of galaxy types – from those with wound-up spiral arms to compact balls of stars – that it does. And it turns out that the human eye is much better than a computer at matching up images of real mergers with randomly-selected images of simulated mergers [SPACE.com]. So naturally, astronomers want to enlist the eyes of Internet users to help them.

The website, Galaxy Zoo Mergers, features a new game that bears (it must be said) only a mild resemblance a Vegas slot machine, with a real galactic merger image in the middle and eight randomly selected images of simulated mergers in the slots around it. Players pick out the best matches and can even manipulate the number of stars they see or an image’s orientation to make a better match. Says researcher Chris Lintott: “By randomly cycling through the millions of simulated possibilities and selecting only the very best matches, they are helping to build up a profile of what kinds of factors are necessary to create the galaxies we see in the universe around us – and, hopefully, having fun, too” [SPACE.com].

This is the latest project from Galaxy Zoo to rely on crowdsourcing. Over the past two years, Galaxy Zoo has enlisted 250,000 Internet users to classify hundreds of thousands of galaxies from the Sloan Digital Sky Survey – an effort that so far has resulted in 15 scientific papers, either submitted or published [MSNBC]. This new project will focus on 3,000 merger images, including some new ones taken by the Hubble Space Telescope. The researchers say their attempts to understand the dynamics of a galactic merger is like trying to understand a car crash– they hope to find out what caused it, and what the final outcome will be for the galaxies involved.

IBM’s Billion-Neuron Simulation Can Match a Cat’s Brainpower

submit to reddit

BlueMatter220An artificial brain as powerful as a human’s remains a distant goal, but scientists are inching closer. This week IBM announced that by using a brain-simulating algorithm called BlueMatter, researchers created an artificial brain simulation that packs more brainpower than a cat.

Researchers used an IBM supercomputer at the Lawrence Livermore Lab to model the movement of data through a structure with 1 billion neurons and 10 trillion synapses, which allowed them to see how information “percolates” through a system that’s comparable to a feline cerebral cortex [San Jose Mercury News]. The team’s previous effort two years ago, modeled after a rat brain, simulated only about 55 million neurons.

The staggering surge in computing power has engineers like IBM’s Dharmendra Modha drooling over the possibilities for more brain-like computers. By reverse engineering [the] cortical structure, Modha says, researchers could give machines the ability to interpret biological senses such as sight, hearing and touch. And artificial machine brains could process, intelligently, senses that don’t currently exist in the natural world, such as radar and laser range-finding [Popular Mechanics].

It should come as no surprise that the design suggests such military applications, as DARPA provided much of the funding. But like the Internet and other technologies originally developed for the military, BlueMatter’s abilities could lead in a multitude of directions. “As our digital and physical worlds collide, there is a tsunami of information,” Modha said. “There is a need for a new kind of intelligence that can sort through, prioritize and extract the most important information, much like how the brain deals with sight, sounds, tastes, touch and smell” [San Jose Mercury News].

NASA Invites You to “Be a Martian” & Explore the Red Planet’s Terrain

submit to reddit

be-a-martianWith NASA’s manned space flight program in tumult, it’s an open question when/if human boots will tramp on Martian soil. But the space agency has provided a virtual way for humans to explore the red planet, with its new “Be a Martian” program.

The online project, a collaboration between NASA and Microsoft, enlists the power of crowdsourcing. Users are invited to sort through the hundreds of thousands of photos of Mars that have been sent back by rovers and orbiters. To convince people to spend hours pouring over pictures of dusty Martian landscapes, two tasks have been set up as games where participants can win points and badges. One game asks people to count craters in photos of Mars; the other asks people to match small, high-res photos of the Martian surface with their corresponding locations on a low-res photo taken from a higher altitude [Seattle Post-Intelligencer]. (You’ll need to have Microsoft’s Silverlight application for the games and videos on the site to work.)

By enlisting citizen scientists, NASA hopes to both interest students in space careers and to make real progress in Martian research. “We really need the next generation of explorers,” says Michelle Viotti, from the agency’s Jet Propulsion Laboratory, which oversees Mars missions. “And we’re also accomplishing something important for Nasa. There’s so much data coming back from Mars. Having a wider crowd look at the data, classify it and help understand its meaning is very important” [BBC News].

Computer Glitch Delays Airline Flights Around the Country

submit to reddit

airline220Air travelers around the country saw their flights delayed this morning, thanks to a computer glitch. The problem, which occured [sic] in the Atlanta-based computer system that provides data about flight plans, has forced air controllers to input the information manually, said Arlene Salac, FAA spokeswoman in New York [Reuters].

The Federal Aviation Administration tried to assure travelers that the problem wasn’t a safety concern; rather it fouled up ground stops and caused delays. The problems began a little after 5 a.m. Eastern time, and hit Atlanta’s busy airport the hardest. One passenger said that a Delta Air Lines gate agent had announced that the glitch prevented pilots from accessing flight plans, the Atlanta Journal-Constitution reported [The New York Times].

The computer problem has been fixed, though FAA spokeswoman Kathleen Bergen said she doesn’t know how many flights have been affected [MSNBC]. And today’s glitch was the second such one in 15 months.

How to Prevent Heart Hackers From Turning Off Pacemakers

submit to reddit

no-pacemaker-sign-webMany medical devices come equipped with wireless communication systems these days, allowing doctors to customize their operations or to see their patents’ information. But fitting pacemakers or implanted defibrillators with WiFi also opens the door to hackers‘ attacks. Hackers could potentially steal personal information, remotely drain batteries, or cause a dangerous malfunction, so researchers are working on ways to block them. The approach relies on using ultrasound waves to determine the exact distance between a medical device and the wireless reader attempting to communicate with it [Technology Review]. The plan is to only allow access to a medical device from wireless reading devices within 10 feet, and only then after a series of authentication steps. However, in the event of an emergency, the medical device would grant access to anyone within a few inches of the device. In other words, to anyone close enough to assist.

The research team also has to consider how much power their security measures will drain from the devices, which is a not-so-trivial point for a  battery-operated pacemaker. But Claude Castelluccia, who was involved with designing the security system, said that because the device won’t respond to requests that come from outside the predetermined distance, it would also be harder for an attacker to wear down the battery by forcing it to process one request after another [Technology Review]. To test their system, researchers recently implanted a medical device in the stomach of a cow, and they’re currently shopping their patented technology to potential developers.

Bankrupt Spam King Is Ordered to Pay Facebook $711 Million

submit to reddit

facebook-webThe self-proclaimed spam king of the Internet, Sam “Spamford” Wallace, was ordered to pay Facebook $711 million in civil damages for slinging spam on the social networking site. Wallace allegedly accessed Facebook accounts without obtaining permission, and used them to make bogus wall posts and spam the account holders’ friends. Those actions run afoul of the CAN-SPAM Act of 2003, which sets guidelines for commercial e-mails, which are enforced by the Federal Trade Commission (FTC) [PC World]. The judge also referred Wallace to the U.S. Attorney’s Office with a request that he be prosecuted for criminal contempt, which means he could actually face jail time if convicted.

If you’ve ever received an unsolicited email (and who hasn’t), chances are good that it came from Wallace’s company, Cyber Promotions, which was once the largest source of spam. So not surprisingly, this isn’t the first time Spamford has run afoul of the law. In May, 2008, MySpace won a $230 million judgment against Wallace for sending junk messages. Wallace was also fined $4 million by the Federal Trade Commission in 2006 for his excessive pop-up ads [CNN]. Officials at Facebook said they don’t expect to see much of the $711 million, seeing as how Wallace is bankrupt and may soon have to send out his spam as hand written letters from behind bars.

America’s Electronic Waste Is Polluting the Globe

submit to reddit

e-wasteIt seems that every day brings a new electronic gadget to the market, whether it’s a smart phone, an electronic reader, a laptop the size and weight of a magazine, or a television the size of a wall. But each advance adds to the world’s electronic waste, which is the fastest-growing component of solid waste. Much of the electronic refuse ends up in developing countries, where workers strip down the gadgets to get at the copper and other valuable metals inside, often exposing themselves to toxins in the process. Now, scientists are calling for federal regulations in the United States to stem the tide.

Although the U.S. is one the world’s largest producers of electronic waste (e-waste), it is hardly a leader in addressing this problem, given that the country has “no legally enforceable federal policies requiring comprehensive recycling of e-waste or elimination of hazardous substances from electronic products,” the researchers say [Scientific American]. Instead, e-waste policies are left to the states, not all of which have laws on the books. In the article, published in Science, the authors note that the United States has not ratified the Basel Convention, which regulates the movement of hazardous wastes across international borders and has the support of 169 of the 192 United Nations member countries [Scientific American].

Electronics can contain a host of dangerous materials, from heavy metals to toxic chemicals. Toxic e-waste shows up in forms as varied as high lead levels in the blood of children in Guiya, China, where millions of tonnes of e-waste are illegally dumped, and as fire-retardant chemicals in the eggs of California’s peregrine falcons [CBC News].

Happy 40th Birthday, Internet! (Um, Again.)

submit to reddit

ARPANETYes, in early September we sent the Internet our birthday best wishes, noting that it had been 40 years since computer scientists at the University of California, Los Angeles connected two computers via a 15-foot cable, allowing for the transmission of data between them. But it wasn’t until October 29, 1969 that the first message passed between two different computer nodes, one at UCLA and the other at Stanford University. The message that researcher Leonard Kleinrock intended to send to Stanford was “login” but Kleinrock was only able to type “lo” before the system crashed. On his second attempt, the message went through successfully [ABC News]. With that, a net was born.

The system dubbed ARPANET, which was funded by the U.S. Department of Defense, would lead directly to the Internet that we know, love, despise, and rely on utterly today. To date, over 1 billion people are online, and last year, Google announced that it had detected over 1 trillion pages [PC World].

Vinton Cerf, an Internet pioneer and the current Chief Internet Evangelist at Google says the online world will continue to evolve in ways we can barely imagine, but which serve humanity’s basic drive to communicate. “Don’t let anyone tell you that information is power…. It’s information-sharing that’s power” [LiveScience], he says.

IBM’s “DNA Transistor” Could Sequence Genomes on the Cheap

submit to reddit

IBM-DNAWhen the Human Genome Project finished sequencing the first human genome earlier this decade, the price tag for the endeavor had reached almost $3 billion. Now, IBM has announced details of its effort to bring the cost of sequencing a person’s genome down to below $1,000–and the company says it could go as low as $100. While IBM is hardly the only company racing towards these goals, the company’s chip-based approach makes it a serious contender.

The company’s technique involves drilling tiny nanometer-size holes through computer-like silicon chips, then passing DNA strands through them to read the information contained in their genetic code. “We are merging computational biology and nanotechnology skills to produce something that will be very useful to the future of medicine” [Wired.com], says IBM scientist Gustavo Stolovitzky.

Stolovitzky says the work could usher in a new era of personalized medicine, in which patients routinely have their genomes scanned to help doctors make medical decisions. “Ultimately, it could improve the quality of medical care by identifying patients who will gain the greatest benefit from a particular medicine and those who are most at risk of adverse reaction,” said Stolovitzky [InformationWeek].

And the Nobel Prize for Physics Goes to…

submit to reddit

Charles-KaoThree scientists who mastered light through technology have been awarded this year’s Nobel Prize for physics, for breakthroughs that the prize committee said “helped to shape the foundations of today’s networked societies.” Half of the $1.4 million prize goes to Charles Kao (pictured), for his work on fiber optics, while the other half will be divided between Willard Boyle and George Smith, two retired researchers from Bell Labs who invented the first imaging technology using a digital sensor instead of film, paving the way for the creation of digital cameras.

Kao’s discovery in fiber optics set the stage for the technological revolution that underpins today’s global communication systems, powering broadband internet connections and carrying data transmissions around the world. In 1966, he figured out how to transmit light for more than 100 kilometers using optical glass fibers, five times the length of the most advanced fibers then available [Bloomberg]. Fiber optics have become ubiquitous in today’s wired, networked world; the Nobel committee noted that if all the optical cables in use today were unraveled, it would equal a single thread more than a billion kilometers long, enough to circle the globe 25,000 times.

Spying Made Simple: Wi-Fi Signals Used to See Through Walls

submit to reddit

wifi-through-wallsLooking for an easy, cheap way to spy on your neighbors? Researchers are working on a device that may be just the thing, which uses a simple wireless network to “see” through a wall and detect people moving around in the room beyond. But paranoid apartment-dwellers will be glad to know that the system still has plenty of limitations. At the moment the system can only track movement within a three-foot range, and it can only sense motion–it can’t put together a picture of what or who’s moving.

The system relies on the variations of radio signals in a wireless network. The signal strength at any point in a network is the sum of all the paths the radio waves can take to get to the receiver. Any change in the volume of space through which the signals pass, for example caused by the movement of a person, makes the signal strength vary. So by “interrogating” this volume of space with many signals, picked up by multiple receivers, it is possible to build up a picture of the movement within it [Technology Review]. The paper describing the technology has been posted on the arXiv pre-print server, and has not yet been peer-reviewed.

The device could be more than a boon for voyeurs or robbers. The researchers argue that the technology could be used in search and rescue operations, with emergency teams using the same radio technology used by Wi-Fi networks to build a web of sensors around a disaster site, revealing the location of victims and survivors [Telegraph].
