iBrain: Stanford professor to hack into Stephen Hawking’s brain

Stanford University professor and CEO of Neurovigil Philip Low has developed iBrain and is working with Stephen Hawking to access the famous physicist’s brain waves. iBrain is a brain scanner that records EEG data and communicates them through a computer.

Low and his team are working on finding a way to bypass Hawking’s body and access his brain directly. Stephen Hawking, 70, has motor neurone disease and has not been able to talk for almost three decades. He used to use a clicker which enabled him to activate his voice machine but his condition worsened and he currently has to use a “cheek switch.” With this, he takes several minutes to form a message.

The iBrain does not have to be implanted into the brain; it only has to be worn. It is made up of a black head harness with a small electronics box and electrodes that will be attached to the patient’s head.

In Low’s meeting with Hawking, he asked the physicist to concentrate on imagining moving his hands and limbs while wearing the device. Low’s goal was to determine if there was any change in the impulses. There indeed was a change in the signal.

Such biomarkers mean that it is possible for intended movements to be linked to words and then converted into speech. This will enable motor neurone sufferers to communicate using tools that will depend more on the brain than on the body. As the technology progresses, it is hoped that more sophisticated brain activities will be recognized and turned into words.

Other possible medical applications of the iBrain in the future include helping doctors prescribe the right amount of medication (by studying a patient’s brainwave responses), as well as helping in the treatment of sleep problems, depression, and autism.

Canon to release mixed reality system in July 2012

Canon will be releasing a mixed reality system late next month. The system will immerse users in an interactive environment that combines physical and virtual objects. It uses high-precision, high-speed image processing to synthesize real-time images which will look as big as their real-world counterparts.

Although expected to be useful in several industries, Canon is set to initially market the augmented reality system to the industrial design sector. Here, the system can make product design and planning faster as well as cheaper since product evaluations can be done using virtual or CG data instead of physical models.

You can see the head-mounted display (HMD) and the software for moving the HMD in this video:

A stereo camera built into the HMD captures the real-world images. The camera’s optical axes are aligned with the light entering the pupil. The lens, called a free-curve prism, highly magnifies the pictures on the display, making the images look large, while keeping the system small.

If needed, motion capture sensors, markers, and gyro sensors can be used to align position. Canon also aims to offer developers an SDK to enable them to develop their own MR applications.

Smart bed makes itself — lazy people everywhere rejoice!

If you find making your bed in the morning a tedious chore, then good news for you. Spanish firm OHEA has come up with a smart bed that will make itself within 50 seconds after you get up.

How does it work? The bottom sheet is attached via Velcro to the mattress cover, keeping the sheet in place. A mechanical arm on each side of the bed includes a roller which carries the blanket to the head of the bed. The pillows are lifted as the blanket approaches, then lowered once the blanket has been placed underneath.

A switch at the foot of the bed allows the bed’s self-straightening function to be set manually or automatically. If you’re too lazy busy to manually activate the bed, you can just set it to ‘automatic’ and the bed will make itself three seconds after you get out of the bed.

For safety reasons, the self-straightening mode won’t activate if pressure is applied or if someone is still in the bed.

See OHEA’s smart bed in action:

The smart beds and their specialty beddings will be available in five sizes beginning next month. Prices will be announced later.

Personally, I don’t think this bed is for me. Sure, the novelty factor is nice. But I like sticking my feet out of the blanket, putting my feet up on a pillow, and hugging another pillow. Besides, the blanket moving by itself makes me feel as if I have a resident ghost in my bedroom. How about you?

South Korea bans virtual item trading, game bots and farms

It’s no secret that South Korea, where Internet penetration rate is above 93%, has a very active gaming culture. Whereas curfews for gaming are already in existence, the country has now officially banned the trading of virtual game items in massively multiplayer online games.

According to Kim Kap-Soo, head of the content policy division of South Korea’s Ministry of Culture, Sports and Tourism, they are implementing the ban because games are meant for entertainment and “should be used for academic and other good purposes”. The move aims to cut down the time teens waste on acquiring virtual goods, since the ministry sees the collection of virtual items for commercial gain as a hindrance to developing a healthy game culture.

The country has also banned the use of bots within games (such as Blizzard’s Diablo 3), making it illegal to farm gold and other items while the player is away from the computer.

The use of bots is already disallowed by the games themselves, but now, players caught farming, trading or botting will face quite a steep penalty — a fine of up to 50 million won (~$42,000) and a maximum jail sentence of five years.

The government’s crackdown on botting will definitely help game creators who spend a lot of time enforcing bans within the games. The ministry estimates that more than 60% of items traded virtually are collected using bots.

Scientists rehabilitate damaged spinal cord to treat paralysis

Researchers at École polytechnique fédérale de Lausanne (EPFL) have found a way to awaken a dormant spinal column and enable paralyzed rats with spinal cord injuries to walk and run again.

The brain and spinal cord possess neuroplasticity — the ability to physiologically adapt to moderate injury. However, the plasticity of the spinal cord expressed has been up until now insufficient to handle severe injury. Research led by Grégoire Courtine, who holds the International Paraplegic Foundation (IRP) Chair in Spinal Cord Repair at EPFL, demonstrates that recovery is possible, provided that the innate intelligence and regenerative capacity of the dormant spinal column is awaken first.

This is done by injecting the rats with a monoamine agonist solution. The chemicals in the solution bind to certain dopamine, adrenaline, and serotonin receptors on the spinal neurons, taking the place of neurotransmitters released by brainstem pathways in unparalyzed subjects and exciting neurons controlling leg movement.

After 5-10 minutes, electrodes implanted in the epidural space of the spinal canal electrically stimulated the spinal cord. This stimulation continuously sent electrical signals through nerve fibers to the excited neurons.

In 2009, Courtine already succeeded in restoring involuntary movement to paralyzed rats. Using a treadmill, rats with a stimulated spinal column were able to walk — the treadmill’s movement created sensory feedback and the spinal column’s innate intelligence took over, enabling the rat to walk without the need for a signal from the rat’s brain. This study convinced the scientists that voluntary movement only required a very weak brain signal.

When Courtine replaced the treadmill with a robotic harness and trained the rats using chocolate at the platform’s far end as reward, the rats’ willpower resulted in nerve fibers regrowing throughout the brain and spine. These new fibers bypassed the original spinal damage and transported brain signals to the electrochemically-awakened spine. The signal was strong enough to enable the rats to walk voluntarily towards the reward using their hind legs.

After several weeks of using the harness and electrical-chemical stimulation, the rats were voluntarily walking, sprinting, climbing up stairs and avoiding obstacles while under stimulation.

It is still unclear if such rehabilitation methods could work for humans, but lead author believes that the results give hope that new treatment methods for paralysis can be developed. Courtine hopes to begin human, phase-two trials in 1-2 years at Balgrist University Hospital Spinal Cord Injury Centre in Zurich, Switzerland. EPFL researchers, in the meantime, are working on NeuWalk, a project which involves designing a spinal neuroprosthetic system, similar to the one used with the rats, that can be implanted into humans.

Kaspersky discovers super cyberweapon called “Flame”

Experts at Kaspersky Lab have discovered an extremely complex spyware actively used as a cyber weapon in several countries. The malware is more complex than other cyber threats previously known. Called Flame (detected as Worm.Win32.Flame by Kaspersky Lab’s security products), the malicious program is designed for cyber espionage and can steal important information such as files, screenshots, contact data, network traffic, system information, and even audio conversations.

The malicious program was discovered by Kaspersky Lab while investigating another destructive malware called Wiper, which was reported by UN’s International Telecommunication Union (ITU) to be deleting computer data across the Middle East. According to preliminary analysis, Flame has been in existence since March 2010, just undetected by security software because of its high sophistication and narrowly targeted attacks.

Flame’s geography of attacks and narrow selection of target computers through the use of specific software vulnerabilities are similar to those of notorious cyberweapons Duqu and Stuxnet. These indicate that Flame belongs to the same category of these super-cyber weapons used in the Middle East for cyberwar and cyberespionage.

According to Kaspersky Lab CEO and co-founder Eugene Kaspersky, “It’s important to understand that such cyber weapons can easily be used against any country. Unlike with conventional warfare, the more developed countries are actually the most vulnerable in this case.”

Flame mainly steals information from infected machines then sends the information to a network of command-and-control servers across the globe. The fact that it can steal various kinds of information makes it one of the most complex and complete attack-toolkit ever known. This malware can replicate over a local network and removable media using several methods, such as Stuxnet’s use of printer vulnerability and USB infection.

Flame is made up of about 20 modules comprising around 20 megabytes of executable code. It is about 20 times larger than Stuxnet and its operators can later on upload new modules to expand the spyware’s functionality. Because of these, a large group of highly-experienced security experts and reverse engineers is needed to analyze this cyber threat. Running and debugging Flame is a lot more complicated since Flame consists of several DLL files loaded on system boot instead of being an ordinary executable program.

The goals of Flame’s creators are yet unknown but since the malware does not steal money from bank accounts and is different from the simple malware created by hacktivists, Kaspersky Lab suspects one or more nation states are behind it. The top 7 countries Flame affects are Iran, Israel, Sudan, Syria, Lebanon, Saudi Arabia, and Egypt.
