Your mind: it's just another piece of hardware. Make sure you download the latest patch and upgrade to the newest operating system.That, in so many words, is the fate of humankind described by David Pescovitz
"We always want to better ourselves. And we're always looking for shortcuts, easier ways to achieve our end goal," said Timo Hannay, the head of Web publishing of the Nature Publishing Group who used to work as a neurophysiologist studying the molecular mechanisms of memory.
Current research has enabled non-human primates to play the old video game Space Invaders using nothing but their own thoughts, said Daniel Marcus, director of the Neuroinformatics Research Group at Washington University School of Medicine. Scientists measure the activity of neurons while a monkey plays Space Invaders with a joystick, and then connect the monkey's brain signals to a device that performs the functions of a joystick without requiring any physical manipulation.
"Eventually, you can take the joystick away and the monkey learns to control the video game using its own neural signals," Marcus said.
The Space Invaders experiment has been performed in at least one human trial, Marcus said in an interview after the panel discussion. Marcus isn't involved in this research himself but is excited about its potential.
"I think it has a lot of potential for quadriplegics," Marcus said. "They just want to have some sort of interaction with their environment, to be able to feed themselves, to type something into a computer and communicate. That really seems realistic to me. The idea of being able to fully control a body is a long ways off, but these are steps in that direction."
In a separate project, one brain-controlled gaming system is already being demoed, with mixed results.
Experts doubts we'll all be cyborgs 50 years from now, but says even healthy people might benefit from some sort of brain interface that connects to – well, something.
Research is limited right now. Scientists are measuring the activity of only 100 neurons or so at a time, which means that while a monkey can use its head to play Space Invaders it still needs to use its hands to play a more complicated game such as the maze-like Pac-Man, according to Marcus.
Marcus's own research involves the brain scanning technology fMRI, which pinpoints the areas of the brain that light up in response to visual stimuli or other triggers. His work analyzing Alzheimer's disease illustrates some of the dangers that might accompany any attempt to re-engineer the human brain.
When we're not doing anything, our brains switch to a default mode, which appears to have major importance and perhaps has something to do with memory. The parts of the brain most involved in this default mode are also the ones most affected in the brains of people suffering from Alzheimer's.This seems to indicate that in some humans, the normal functioning of the brain is damaging itself, and is something that has to be considered when performing any future "mind hacks"
What does it mean for you? Probably not much for now, but Pescovitz looks forward to the day when businesses have brain fitness centers for their employees, complete with vending machines loaded with pharmaceuticals and kiosks that zap your mind with magnetic waves. Goodbye, Starbucks, hello Skynet.

GiFi-Latest Research In Wireless Technology
Researchers of Melbourne University has come up with a wireless technology which promises high speed short range data transfers with speeds of upto 5 Gbps within a radius of 10 meters. The new wireless technology is named GiFi operates on the 60GHz frequency band, which is currently mostly unused. The GiFi Chip developed by the Australian researchers measures 5mm square and is manufactured using existing complementary metal-oxide-semiconductor (CMOS) technology, the same system that is currently used to print silicon chips.
The best part about this new technology is its cost effectiveness and power consumption, it only consumes 2 watts of power for its operation with antenna(1mm) included and the development of Gi-Fi chip costs approximately $10( Rs 380) to manufacture.
In theory this technology would transfers GB’s of your fav high definition movies in seconds. So GiFi can be considered as a challenger to Bluetooth rather than Wi-Fi and could find applications ranging from new mobile phones to consumer electronics.
Mass production of the technology might not start before 2009.

New Cell Phone Batteries to Last for Months
Researchers from Stanford University have discovered a new way to use silicon nanowires in rechargeable batteries that power mobile phones, laptops,
video cameras, iPods and other similar devices. The new batteries will be able to store up to ten times more electrical power than existing Li-Ion batteries. "It's not a small improvement. It's a revolutionary development", said Yi Cui, assistant professor of materials science and engineering, who lead the research for the new battery technology. Thanks to the new concept, a mobile phone that now has a stand-by time of 6 days could operate for 60 days with a single full battery charge. The same goes for laptops, video cameras and other devices – they will be able to provide a much longer operating time compared to the one they are currently capable of. A standard Li-ion battery has an electrical storage capacity limited by the amount of lithium that can be retained in the battery's anode, usually made of carbon. When made of silicon, the anode can retain much more lithium, but silicon's disadvantage is that it pulverizes during charging cycles, lowering the battery's performance and life-cycle. The Stanford research team found a way to avoid this problem, by leveraging on nanotechnology. To store lithium, they use silicon nanowires, each with a diameter one-thousandth the thickness of a paper sheet. When soaking up lithium, the nanowires grow four times their size and then come back to normality, but due to their extremely small wired shape, they don't fracture in time. Hence silicon is better than carbon after all, it only has to be used as nanowires. This expanded storage capacity that Li-ion batteries proved to be capable of could make them appropriate for electrical cars and, as Mr. Yi Cui believes, also for homes and offices, where they could be used to store electricity produced by rooftop solar panels. Although the new batteries are not yet available, the Stanford team has filed for a patent and, hopefully, the batteries will start to be manufactured in 2008. Charging your mobile phone only six times a year – imagine that!

3 TB Hard Disk planned by 2010 by Western Digital
Western Digital, a leading maker of hard disk drives, has announced that it had achieve record areal density using its perpendicular magnetic recording (PMR)/tunneling magneto-resistive (TuMR) head technology. The achievement will allow the company to product 3TB hard disk drives in about three years time.
Following WD’s growing investments in technology the past five years, the company achieved 520Gb/inch² using its own perpendicular magnetic recording (PMR)/tunneling magneto-resistive (TuMR) head technology. This level of density produces a 3.5” hard drive storing 640GB-per-platter and single hard drive capacities as large as 3TB. Based on the industry’s current density growth rate of more than 40% per year, those capacities are expected to be available in the 2010 time frame.
Earlier this month Hitachi-GST also indicated that it expected to achieve areal density of 500Gb/inch² – 1Tb/inch² using perpendicular magnetic recording and current perpendicular-to-the-plane giant magneto resistive (CPP-GMR) heads and touted 4TB hard disk drives (HDDs) in 2011.
WD demonstrated 520Gb/inch² density in its Magnetic Head Operation labs in Fremont, California, earlier this month.
“The milestone was realized using our current-technology MgO reader, illustrating the extendibility of PMR-TuMR head technology generations into the future,” said Hossein Moghadam, chief technology officer for WD.

A Robot Bride by 2050?
An artificial intelligence researcher predicts that robotics will make such dramatic advances in the coming years that humans will be marrying robots by the year 2050.
Robots will become so human-like -- having intelligent conversations, displaying emotions and responding to human emotions -- that they'll be very much like a new race of people, said David Levy, a British artificial intelligence researcher whose book, "Love and Sex with Robots," will be released on Nov. 6.
Gone, he says, will be the jerky movements and artificial-sounding voices generally associated with robots. These will be highly human-like machines that people fall in love with, becoming aides, friends and even spouses.
It may sound like science fiction, but Levy, who turned his book into an academic Ph.D. dissertation at Maastricht University in The Netherlands this fall, said it's something we've been moving toward for decades now.
"Robots started out in factories making cars. There was no personal interaction," said Levy, who also is an International Chess Master who has been developing computer chess games for years. "Then people built mail cart robots, and then robotic dogs. Now robots are being made to care for the elderly. In the last 20 years, we've been moving toward robots that have more relationships with humans, and it will keep growing toward a more emotional relationship, a more loving one and a sexual one."
Yes, Levy was quick to say that humans will have sexual relationships with robots, perhaps within five years -- sooner than most might think.
Building that kind of robot will be much simpler than building a robot that could be a good human companion, though. Levy said the biggest advancement in robotics will come in the form of enabling a robot to carry on an interesting conversation, have self-awareness and emotional capabilities.
"There are already people who are producing fairly crude personalities and fairly crude models of human emotions now," said Levy. "This will be among the harder parts of this process... Human/computer conversation has attracted a lot of research attention since the 1950s, and it hasn't made as much progress as you'd expect in 50 years. But computers are so much more powerful now and memory is so much better... so we'll see software that can have interesting, intelligent conversations. It's really essential that both sides are happy with the conversations they're having."
Levy also estimated that robots will be able to have interesting conversations -- not yet at the level of a college graduate but enjoyable -- within 15 years. In 20 or 30 years, however, he expects them to carry on sophisticated conversations.
The robot's specific knowledge, Levy says, will be up to the owner.
According to Levy, people will be able to order a customized companion, whether a friend who enjoys the arts or travel or a spouse.
"There will be different personalities and different likes and dislikes," he said. "When you buy your robot, you'll be able to select what kind of personality it will have. It'll be like ordering something on the Internet. What kind of emotional makeup will it have? How it should look. The size and hair color. The sound of its voice. Whether it's funny, emotional, conservative.
"You could choose a robot that is funny 40 percent of the time and serious 60 percent of the time," he added. "If you get fed up with your robot making jokes all the time, you can just download different software or change the settings on it. You'll be able to change the personality of the robot, its interests and its knowledge. If you're a movie buff, you can ask for a robot with a lot of knowledge about movies."
Levy said he sees great social advantages to having robotic companions. People can fill out their group of friends and shy or lonely people can have the companionship they're lacking.
So, in between watching movies with their human companion and playing Frisbee in the park, will the robots be off leading lives of their own?
Levy said he doesn't think that will happen by 2050, but it could occur by the turn of the next century. "The robot is probably sitting in the corner in your house waiting for you to decide what you'd like to do next... instead of out living a life of its own," he added. "In this time frame anyway, robots will be there when we need them, as we need them."
That, however, doesn't mean they won't become integrated into the family.
In terms of how much time people spend with their robots and how attached they become to them, Levy said robots definitely will become family members. "By mid-century, I don't think the difference between robots and humans will be any more than the difference between people who live in Maine and people who live in the bayou of Louisiana," he noted. "People will be surprised to know that robots will have emotions like ours and they'll be sensitive to our emotions and needs."
So what do researchers need to get robotics to this advanced level?
First, according to Levy, they'll need much more powerful computer hardware that can handle the complex and computational-heavy applications that will be needed to design and run conversational capabilities, along with emotions and more advanced artificial intelligence.
Once the hardware and software needs are in place, Levy said advances in robotics will quickly begin to multiply.
