The most accurate clock of all time

May 19, 2005

A strontium atomic clock has set another benchmark, with an accuracy of 1 part in 10^18, 1000 times more accurate than any of its predecessors.

Pocket Printer

January 7, 2008
Polaroid printer prints photos on two-inch-by-three-inch sheets of paper, without using ink or toner, using a novel type of thermal-printing technology: a special paper contains layers of crystals that release pigment when heated. (Zink)

Polaroid spinoff Zink Imaging has unveiled the “digital instant mobile photo printer,” a Bluetooth-coupled color printer available by the summer for less than $150.

Artificial liver uses 3-D modeling

April 25, 2002

Researchers believe they have solved the problem of growing the complex networks of blood vessels that artificial organs would need to sustain themselves within the body.
The idea, so far tested in rats, involves copying the blood vessel network of a real liver and using 3D fractal computer modelling and machining to mimic its construction.

The scinentists use the model to construct a silicon-mould scaffold. They then pump a… read more

Role of mirror neurons may need a rethink

May 27, 2009

Harvard University researchers suggest that the theory that by simulating action even when just watching an act, motor neurons allow us to recognize and understand other people’s actions and intentions, is flawed.

Hubble movies provide unprecedented view of supersonic jets from young stars

August 31, 2011

The glowing, clumpy streams of material shown in these NASA/ESA Hubble Space Telescope images are the signposts of star birth. Ejected episodically by young stars like cannon salvos, the blobby material zips along at more than 700 000 kilometres per hour. The speedy jets are confined to narrow beams by the powerful stellar magnetic field. Called Herbig-Haro or HH objects, these outflows have a bumpy ride through space. When fast-moving blobs collide with slower-moving gas, bow shocks arise as the material heats up. Bow shocks are glowing waves of material similar to waves produced by the bow of a ship ploughing through water. In HH 2, at lower right, several bow shocks can be seen where several fast-moving clumps have bunched up like cars in a traffic jam. In HH 34, at lower left, a grouping of merged bow shocks reveals regions that brighten and fade over time as the heated material cools where the shocks intersect. In HH 47, at top, the blobs of material look like a string of cars on a crowded motorway, which ends in a chain-reaction accident. The smash up creates the bow shock, left. These images are part of a series of time-lapse movies astronomers have made showing the outflows’ motion over time. The movies were stitched together from images taken over a 14-year period by Hubble’s Wide Field Planetary Camera 2. Hubble followed the jets over three epochs: HH 2 from 1994, 1997, and 2007; HH 34 from 1994, 1998, and 2007; and HH 47 from 1994, 1999, and 2008. The outflows are roughly 1350 light-years from Earth. HH 34 and HH 2 reside near the Orion Nebula, in the northern sky. HH 47 is located in the southern constellation of Vela (credit: NASA, ESA, and P. Hartigan (Rice University))

An international team of scientists led by Rice University has combined two decades of Hubble observations to make unprecedented high-resolution, time-lapse movies revealing never-before-seen details of young jets, the birth pangs of new stars.

The movies reveal the motion of the speedy outflows as they tear through the interstellar environments. Never-before-seen details in the jets’ structure include knots of gas brightening and dimming… read more

Toyota Aims To Sell Service Robots By 2010

May 31, 2005

Toyota Motor Corp. aims to start selling robots that can help look after elderly people or serve tea to guests by 2010.

DNA Deletion Linked to Autism

January 10, 2008

A massive new study of the genetics of autism could lead to diagnostic tests and, eventually, to the identification of new drug targets.

Consciousness Based on Wireless?

May 21, 2002

Prof. JohnJoe McFadden argues that human consciousness is the brain’s electromagnetic field interacting with its neural circuitry.

Commonly used medications may produce cognitive impairment in older adults

June 2, 2009

Many drugs such as sleeping pills commonly prescribed to older adults for a variety of common medical conditions including allergies, hypertension, asthma, and cardiovascular disease appear to negatively affect the aging brain.

The drugs cause immediate but possibly reversible cognitive impairment, including delirium, in older adults, according to senior study author Malaz Boustani, M.D., Indiana University School of Medicine associate professor of medicine, Regenstrief Institute investigator, and research scientist… read more

Nano-stamping makes its mark

June 14, 2005

Researchers at Massachussetts Institute of Technology and Virginia Commonwealth University reckon their supramolecular nanostamping printing technique could enable the mass production of nanodevices. The method uses DNA hybridization to replicate a pattern and has a resolution of less than 40 nm.

Self-Paced Brain-Computer Interface Gets Closer to Reality

January 16, 2008

University of British Columbia researchers have developed a self-paced brain-computer interface with both a low false-positive rate and a high true-positive rate.

Improved software and other methods allows the interface to detect neurological phenomena in an environment with a very low signal-to-noise ratio.

Nanobots in the brain featured on CBS ’48 Hours’

June 17, 2002

On CBS “48 Hours” Friday night, Ray Kurzweil predicted the use of nanobots (nanorobots) to enhance brain power. Billions of nanobots will “take up positions in the brain and communicate with each other,” he said. “They’ll actually expand the human brain, add more memory, more cognitive capabilities. You’ll be able to download skills into the nonbiological portion of your intelligence… [and] do things you otherwise wouldn’t be able to do,”… read more

Tangled proteins may spread Alzheimer’s through brain

June 8, 2009

The transmission of abnormal tau proteins that form tangles in cells may explain how Alzheimer’s spreads throughout a patient’s brain, Laboratory of Molecular Biology researchers have found.

Tapping innovations in China’s industrial parks

September 14, 2011

Lux Research has published a comprehensive analysis of the more than 1,500 established industrial parks in China, based on location, technology capability, technology focus, and domestic and foreign content.

The report, titled “Seeing the Forest and the Trees: Navigating China’s Industry Park Innovation Engine,” educates technology scouts on the unique opportunities for innovation within this high growth market, and guides prospective R&D and manufacturing entrants… read more

What Other People Say May Change What You See

June 29, 2005

A new study used advanced brain-scanning technology to cast light on a topic that psychologists have puzzled over for more than half a century: social conformity.

They found evidence that other people’s views can actually affect how someone perceives the external world, implying that truth itself is called into question.
