Would you use eye-tracking instead of passwords?

July 18, 2013

The prototype was built to simulate an ATM screen. In this scenario, users followed the highlighted dots with their eyes and the technology tracked their unique eye movements.

Biometric authentication technology systems for fingerprint, eye, and face recognition have failed to go mainstream to replace the unreliable password system.

University of Washington engineers are trying to figure out why. They found in a recent study, funded by the National Institute of Standards and Technology, that one of the reasons face- and eye-recognition systems haven’t taken off is because the user’s experience often isn’t factored into… read more

Would you trust a humanoid robot?

July 7, 2010

Northeastern University psychology professor David DeSteno and colleagues are conducting innovative research to determine how humans decide to trust strangers — and if those decisions are accurate.

The researchers are examining whether nonverbal cues and gestures could affect our trustworthiness judgments. “People tend to mimic each other’s body language,” said DeSteno, “which might help them develop intuitions about what other people are feeling — intuitions about whether they’ll… read more

Would you pay $68,000 to unlock the secrets of your genetic code?

May 1, 2009

Bidding kicked off last week at $68,000 on a 10-day eBay auction whose prize includes personal genome sequencing, analysis, and interpretation services provided by Cambridge, Mass.-based genetics firm Knome, Inc.

The auction’s winner also participates in a roundtable discussion with Knome’s geneticists, clinicians and bioinformaticians to review the winner’s sequence data, and a private dinner with George Church, co-Founder and Knome’s chief scientific advisor.

The auction is intended… read more

Would you have allowed Bill Gates to be born?

June 1, 2005

There is a good chance we will soon have a genetic test for detecting the risk of autism in an embryo or fetus.

The development of such a screening tool raises the possibility that parents might one day have the option of preventing the birth of a child with even a mild form of the disorder.

As genetic testing moves into the world of mental health, we are… read more

Would you give up your immortality to ensure the success of a posthuman world?

July 30, 2007

On Wednesday at TransVision 2007, Marvin Minsky puckishly suggested we could solve any population problem by uploading the minds of 10 billion people and running them on a computer that occupies a few cubic meters and costs only a few hundred dollars to run.

Ray Kurzweil claimed that longevity trends are accelerating so fast that the life expectancy will increase more than one year for each year… read more

Would you eat ‘eco-friendly’ meat created from stem cells?

May 23, 2014

cells to food

In a paper in the Cell Press journal Trends in Biotechnology, Cor van der Weele of Wageningen University in The Netherlands and coauthor Johannes Tramper describe a potential meat manufacturing process, starting with a vial of cells taken from a cell bank and ending with a pressed cake of minced meat.

Cor van der Weele  point out that the rising demand for meat around the world is… read more

Would You Buy a Car From a Robot?

December 12, 2002

Honda is using its Asimo walking-talking robot as a promotional tool, reciting information about cars in showrooms and appearing in commercials and at events.

Asimo uses the visual information from a camera to recognize ten different preprogrammed faces, follows movements, and takes direction for its movements.

Worse Than Gray Goo

February 24, 2004

“If we ever get to the point where script kiddies can release dangerous gray goo, we’re probably doomed –since it’ll surely be harder to stop goo than to stop slow-moving, slow-thinking meat robots from pushing the wrong buttons, says Center for Responsible Nanotechnology Director of Research Chris Phoenix.

“But we will have much more severe dangers to deal with before that point. Like nano-arms races with weapons much more… read more

Wormhole ‘no use’ for time travel

May 24, 2005

A new study by Stephen Hsu and Roman Buniy of the University of Oregon says the idea of building a traversable wormhole may be fundamentally unstable.

However, they also assert that “semi-classical” wormholes — in which the space-time “tube” shows only weak deviations from the laws of classical physics — are the most desirable type for time travel because they potentially allow travellers to predict where and when they… read more

Worm-inspired robot crawls through intestines

June 7, 2006

A robot designed to crawl through the human gut by mimicking the wriggling motion of an undersea worm could one day help doctors diagnose disease by carrying tiny cameras through patients’ bodies.

Worm mind control

Using precisely-targeted lasers, researchers manipulate neurons in worms' brains and take control of their behavior
September 25, 2012

CelegansGoldsteinLabUNC

In the quest to understand how the brain turns sensory input into behavior, scientists have crossed a major threshold.

Using precisely-targeted lasers, Harvard researchers have taken over an animal’s brain, instructing miniature nematode worms Caenorhabditis elegans (C. elegans) to turn in any direction they choose by manipulating neurons in the worms’ “brain.”

They even implanted false sensory information, fooling the animal into thinking food was nearby.… read more

Worm Infects Millions of Computers Worldwide

January 23, 2009

A new digital plague has hit the Internet, known as Conficker or Downadup, infecting millions of personal and business Windows-based computers in what seems to be the first step of an unknown multistage attack.

Experts say it is the worst infection since the Slammer worm exploded through the Internet in January 2003, and it may have infected as many as nine million personal computers around the world.

Worm ‘EEG’ tests neural effects of drugs

May 24, 2013

Scientists from the University of Southampton have developed a microfluidic electrophysiological device called a NeuroChip that records the neural activity in the microscopic worm Caenorhadbitis elegans  (C. elegans) — the worm equivalent of an EEG —.to help test the effects of drugs.

How to record a worm’s ‘EEG’

With the NeuroChip, you feed the  worm into a narrow, fluid-filled channel that tapers at… read more

World’s smallest, fastest nanomotor

They could one day move through the body at high speed to deliver drugs to target cells

Researchers at The University of Texas at Austin have built the “smallest, fastest, and longest-running” nanomotor  to date — an important step toward developing miniature machines that could one day move through the body to deliver drugs such as insulin for diabetics when needed, or target and treat cancer cells without harming good cells, the scientists say.

World’s smallest autopilot for micro aircraft

August 27, 2013

RTEmagicC_Fotobijkleinsteautopilot_01.jpg

Researcher Bart Remes and his team of the Micro Aerial Vehicle Laboratory at the TU Delft faculty of Aerospace Engineering have designed, built and tested the world’s smallest open source autopilot for small unmanned aircraft.

A smaller — and lighter — autopilot allows these small flying robots to fly longer, fit into narrower spaces or carry more payloads, such as cameras. That makes them more… read more
