Tasmanian tiger DNA ‘lives’ again

May 20, 2008

University of Melbourne researchers have shown that a DNA fragment taken from Tasmanian tiger samples (the thylacine, extinct for 70 years) can be added to mouse embryos, where the DNA functioned normally in making collagen.

This is the first time that genetic material from an extinct animal has functioned inside a living host. Other researchers have resurrected extinct DNA inside cell lines in the lab.

Greenpeace Wades Into Nano Debate With Report That Calls For Caution

July 28, 2003

Greenpeace has entered the debate over nanotech’s impact on the environment and society with a study that calls for the industry to “demonstrate a commitment to (environmental concerns) by funding the relevant research on a far greater scale than currently witnessed.”

Greenpeace explores the idea that “quantum dots, nanoparticles, and other throwaway nanodevices may constitute whole new classes of non-biodegradable pollutants that scientists have very little understanding of.”… read more

Neuroscientists uncover possible basis of short-term memory

December 28, 2009

The semilunar granule cells in the hypocampus have been found to sustain activity patterns for 10 seconds in mouse brain tissue in vitro, suggesting that these cells are the specific brain region that actually holds a short-term memory.

A common cortical organization among mammals

November 17, 2011

Human Mouse

A new study by researchers at the University of California, San Diego School of Medicine and colleagues using magnetic resonance imaging data of 406 adult human twins affirms the long-standing idea that the genetic basis of human cortical regionalization — the organization of the outer brain into specific functional areas — is similar to and consistent with patterns found in other mammals, indicating a common conservation… read more

Error-check breakthrough in quantum computing

June 8, 2006

An error-checking method that could prove crucial to the development of a practical quantum computer has been developed.

Physicists at the University of California, Santa Barbara, have discovered a new way to check how much the information stored inside a quantum computer has decayed. This is an impressive feat since measuring the state of a qubit normally destroys its quantum properties.

Internet to run out of addresses ‘within 3 years’

May 26, 2008

85 per cent of the 4.3 billion available Internet Protocol (IP) addresses, which identify devices connected to the net, are already in use. Within three years they will all be used up, according to a report by the OECD. “The situation is critical for the future of the internet economy,” it says.

The report urges governments and businesses to upgrade from the current version, IPv4, to IPv6, which effectively… read more

Holographic data storage: Light on the horizon

August 5, 2003

The first commercial holographic memory should be on the market next year. Theoretically, it’s possible to store a terabyte of data on a CD-sized disk, with transfer rate of a billion bits a second (at least 60 times faster than current DVDs).

2020 Vision: Why you won’t recognize the ‘Net in 10 years

January 5, 2010

The National Science Foundation’s Network Technology and Systems (NeTS) program is challenging computer scientists to create an Internet that’s more reliable, better able to manage exabytes of content, without so many security breaches, with better trust and built-in identity management, and that extends connectivity to the most remote regions of the world, perhaps to other planets.

How much do we need to know?

June 21, 2006

We should limit access to information and technologies that could put unprecedented power into the hands of malign individuals, says Bill Joy in the June 17 New Scientist magazine (subscription required).

“Rather than regulate things, we could price catastrophe into the cost of doing business,” he advises. “Right now, if you want approval for things, you go through a regulatory system. If we used insurance and actuaries… read more

A Low-Cost Multitouch Screen

May 30, 2008
(Microsoft)

Microsoft introduced a new multitouch platform, called LaserTouch, which includes hardware that’s cheap enough to retrofit any display into a touch screen.

LaserTouch is a system built on the cheap: the hardware only costs a couple hundred dollars, excluding the display–which can be a plasma television or overhead projector, for instance–and the computer that runs the software. Unlike Surface, which uses a camera within the table to… read more

Biotech a healthy market for chips

August 15, 2003

Intel is planning to develop medical devices using nanotech chips and sensing technology.

Ideas include constructing hemoglobin molecules that can carry 10 times as much oxygen, a diagnostic lab on a chip, toxin-detecting and analysis-capable bandaids, ulcer-detecting stockings for diabetics, and computer feedback systems for diagnosis and treatment of Alzheimer’s Disease.

Disconnect Between Brain Regions in ADHD

January 12, 2010

Two brain areas fail to connect when children with attention deficit hyperactivity disorder attempt a task that measures attention, according to researchers at the UC Davis Center for Mind and Brain and M.I.N.D. Institute.

Digital narcotics may be the future of drugs

December 6, 2011

Technologists will become the next drug dealers, administering narcotics through brain stimulation, suggests Rohit Talwar, the founder of Fast Future Research, speaking at Intelligence Squared’s If conference.

Scenarios:

  • Designer proteins deliver psychotropic effects triggered by electromagnetic stimulation.

Does This Mean People Turned Off, Tuned Out and Dropped In?

June 30, 2006

Speakers of Aymara, an Indian language of the high Andes, think of time differently than just about everyone else in the world. They see the future as behind them and the past ahead of them.

Molecular brakes for nanotechnology machines

June 5, 2008
(American Chemical Society)

National Taiwan University researchers and their colleagues have designed a light-driven molecular brake that could provide on-demand stopping power for nanotech machines.

The brake resembles a tiny four-bladed wheel (a rigid pentiptycene group) and contains light-sensitive molecules. The paddle-like structure spins freely when a nanomachine is in motion. Exposing the structure to light changes its shape so that the blades stop spinning.
