Genome power is about to sweep world: Nobel laureate

June 13, 2011

In a decade, we will have our genome on our smart phones and be able to routinely gain access to those of prospective boyfriends or girlfriends, says Nobel laureate Barry Marshall. People would get used to the ins and outs of knowing their genetic makeup as the benefits to their health became clear and treatment got better targeted, he says.

Marshall plans to become the first Australian to… read more

New robot face smiles and sneers

February 17, 2003

The new K-bot robot can express a full repertoire of human facial expressions and could be a useful tool for scientists researching AI.

She has 28 facial movements, including smiling, sneering, furrowing her brow and arching her eyebrows. She also has cameras in her eyes to recognize and respond to humans.

K-bot is the creation of David Hanson, a former Disney employee now working at the University of… read more

Recreating the Big Bang Inside Metamaterials

August 24, 2009

A phase transition inside a special metamaterial could lead to the sudden creation of an optical analog of the Big Bang, Igor Smolyaninov at the University of Maryland found in mathematical simulations.

A Heart Device Is Found Vulnerable to Hacker Attacks

March 12, 2008

Computer security researchers have shown they could reprogram, shut down and deliver jolts of electricity to a combination heart defibrillator-pacemaker that would potentially be fatal.

They also showed they could glean personal patient data by eavesdropping on the device, made by Medtronic.

Civilisation has left its mark on our genes

December 19, 2005

A detailed look at human DNA has shown that 1800 genes, or roughly 7 percent of the total in the human genome, have changed under the influence of natural selection within the past 50,000 years, probably in response to aspects of modern human culture such as the emergence of agriculture and the shift towards living in densely populated settlements.

Beaming Video at Speed of Light

March 4, 2003

A New Zealand company’s twist on free-space optics — which broadcasts data over visible light spectrum — promises to make wireless data transfer faster and cheaper. It can even beam high-quality video.

Bionic brain chips could overcome paralysis

September 1, 2009

An electronic bypass to a broken connection in the spinal cord may be possible in the future, research at the University of Washington and elsewhere suggests.

Electronic chips would be implanted in the relevant regions of the brain to record neural activity, a decoder would decipher the neural chatter to figure out what the brain wants the body to do, and these messages would be relayed wirelessly to electrodes… read more

‘Mind Gaming’ Could Enter Market This Year

March 17, 2008

The power of the mind may be the next big thing in video games, and it may come soon.

Emotiv says its mind-control headsets will be on shelves later this year, along with a host of novel biofeedback games developed by its partners. Several other companies–including EmSense in Monterey, California; NeuroSky in San Jose, California; and Hitachi in Tokyo–are also developing technology to detect players´ brainwaves and use them… read more

The Quest For Immortality

January 1, 2006

60 Minutes correspondent Morley Safer interviewed Dr. Aubrey de Grey, who says that sometime in the next 20 to 30 years or so, we’ll be able to recondition ourselves for the first steps towards immortality.

Power grid change may disrupt clocks

June 26, 2011

A yearlong experiment by the Federal Energy Regulatory Commission with the nation’s electric grid could mess up traffic lights, security systems, and some computers — and make plug-in clocks and appliances like programmable coffeemakers run up to 20 minutes fast.

Officials say they want to try this to make the power supply more reliable, save money, and reduce what may be needless efforts. The test… read more

Ink Changes Color at Flick of a Switch

March 17, 2003

“A new ink changes colour at the flick of a switch. It could give rise to newspapers that show shifting images, or chemical sensors that display different hues depending on what substance they detect.”

Don’t be fooled: swine flu still poses a deadly threat

September 9, 2009

As swine flu’s autumn wave begins in the northern hemisphere, the H1N1 virus mostly causes mild disease, but fewer than 1 per cent become deathly ill, very fast, and these cases could overwhelm hospitals.

Climbing robot throws its weight around

March 20, 2008

Stanford University researchers have built a four-limbed robot, designed for exploring Martian geology, that climbs vertical walls using foot- and hand-holds like a human climber.

The robot can complete four moves of its arms and legs in 30 seconds.

Cameras on its limbs will allow it to climb without knowing the location of foot- and hand-holds in advance.

A similar robot being developed at Virginia Tech University,… read more

Researchers Discover New Way to Stimulate Brain to Release Antioxidants

January 12, 2006

Burnham Institute Resesarchers and a team from Japan have discovered a novel way to treat stroke and neurodegenerative disorders by inducing nerve cells in the brain and the spine to release natural antioxidants, such as bilirubin, that protect nerve cells from stress and free radicals that lead to neurodegenerative diseases.

In stroke and various neurodegenerative disorders, such as Alzheimer’s disease and Lou Gehrig’s disease, glutamate, an amino acid found… read more

Internet is ‘victim of vicious smear campaign,’ finds report

July 5, 2011

(Credit: Nominet Trust)

A report released July 4 claims that the Internet has actually been the victim of some sort of vicious smear campaign.

Its key conclusions, compiled by neuroscientist Paul Howard Jones of Bristol University:

  • There is no neurological evidence that the Internet is more effective at “rewiring” our brains than other environmental influences.
  • The Internet is a “valuable learning resource and all forms of
