Subtitle-Reading Glasses Make Cinema-Going for the Hard of Hearing Less, um, Hard

April 19, 2007

Madrid’s Carlos III University has developed a gadget that projects subtitles in a movie theater.

A computer in the cinema emits the subtitles to within 50 meters; a receptor in the glasses captures the signal and projects it onto the microscreen, which fits over the right-hand lens.

Subtle nervous system abnormalities may predict risk of death in older individuals

June 23, 2008

University of Florence researchers and colleagues have found that subtle but clinically detectable neurological abnormalities such as reduced reflexes or unstable posture help predict the risk of death and stroke in otherwise healthy older adults–possibly a sign of early brain damage.

These results suggest that a standard neurological exam should become a routine part of healthcare for older adults, because the exam has a predictive value similarread more

Sugar in the gas tank? It might run your car someday

February 1, 2007

Amyris Biotechnologies hopes to convert sugar directly to fuel by reprogramming microbes.

Jack Newman, PhD, Amyris Biotechnologies VP: “Why are we making ethanol if we’re trying to make a fuel? We should be making something that looks a lot more like gasoline. We should be making something that looks a lot more like diesel. And if you wanted to design, you name it, a jet fuel? We can make… read more

Sugar molecules — building blocks of RNA — found around young star

August 30, 2012

Astronomers have for the first time found glycolaldehyde molecules around a young sun-like star. Glycolaldehyde is a an important pre-biotic species, a simple sugar, consisting of carbon, oxygen and hydrogen atoms. Through observations with ALMA the researchers have shown that the molecules are located within a region with an extent corresponding to our own solar system - and thus exist in the gas from which planets possibly are formed around the young star later in its evolution. (Credit: ESO)

A team of astronomers led by researchers from the Niels Bohr Institute, have observed a simple sugar molecule in the gas surrounding a young star, proving that the building blocks of life were already present during planet formation.

They also found other complex organic molecules, including ethylene-glycol, methyl-formate and ethanol.

Sugar solution makes tissues see-through for brain imaging at unprecedented resolution

June 25, 2013


RIKEN Center for Developmental biology researchers have developed a new sugar and water-based solution that turns tissues transparent in just three days, without disrupting the shape and chemical nature of the samples.

Combined with fluorescence microscopy, this technique enabled them to obtain detailed images of a mouse brain at unprecedented resolution.

Over the past few years, teams in the USA and Japan have reported a… read more

Sugar-fuelled battery soon to juice up portable electronics

March 27, 2007

Fuel cell technology that is currently in development boasts the ability of extracting energy from virtually any sugar source to power portable electronics.

The cell operates at room temperature and uses enzymes to oxidize sugars, hence generating electricity.

Suite of chatterbox genes discovered

November 13, 2009

By combining human and chimp Foxp2 genes in a petri dish, University of California, Los Angeles neuroscientists have identified 116 genes controlled by Foxp2 that responded differently to the human version of Foxp2 than the chimp version, supporting Foxp2′s suggested role in the evolution of language and speech.

In another experiment, they found a striking overlap between the genes whose activity was different in the human brain tissue and… read more

Sun president: PCs are so yesterday

September 26, 2005

Increasingly, the personal computer is a relic, says Sun Microsystems president Jonathan Schwartz. Instead, what has become important are Web services on the Internet and the mobile phones most will use to access them.

Schwartz points to the increasing wealth and power of companies, like eBay, Google, Yahoo and, that profit from free services available over the network.

Sun supercomputer takes on IBM’s Blue Gene

June 27, 2007

Sun Microsystems Inc. is aiming to wrest the world supercomputing crown from IBM’s Blue Gene.

Sun’s Constellation, to be installed at the Texas Advanced Computing Center, provides 21 million floating-point operations per second, potentially reaching 2 PFLOPS. IBM already has a 3 PFLOP version of its Blue Gene supercomputer, but Sun could potentially hit the No. 2 spot.

Sun unleashes X6.9 class flare; Earth spared this time

August 10, 2011

An x-class flare began at 3:48 AM EDT on August 9, 2011 and peaked at 4:05 AM. The flare burst from sun spot region AR11263, before it rotated out of view. The image here was captured by NASA's Solar Dynamics Observatory (SDO) in extreme ultraviolet light at 131 Angstroms (credit: NASA)

On August 9, 2011 at 3:48 a.m. EDT, the sun emitted an Earth-directed X6.9 flare, as measured by the NOAA GOES satellite.

This was the largest flare of the current solar cycle, an R3 (Strong) Radio Blackout, alternatively classified as an X6,  according to the U.S. NOAA Space Weather Prediction Center.

These gigantic bursts of radiation can disrupt GPS and communications signals. In this case, scientists… read more

Sun-free photovoltaics powered by heat

August 1, 2011

Silicon chip micro-reactors developed by the MIT team. Each of these contains photonic crystals on both flat faces, with external tubes for injecting fuel and air and ejecting waste products. Inside the chip, the fuel and air react to heat up the photonic crystals. (Credit: Justin Knight)

A new photovoltaic energy-conversion system has been developed by researchers at MIT, powered solely by heat, generating electricity with no sunlight at all.

The researchers made a button-sized power generator fueled by butane that can run three times longer than a lithium-ion battery of the same weight. The device can then be recharged instantly, just by snapping in a tiny cartridge of fresh fuel.

Sun-powered device converts CO2 into fuel

February 19, 2009

Powered only by natural sunlight, an array of catalytic titanium dioxide nanotubes is able to convert a mixture of carbon dioxide and water vapor into natural gas at rates 20 times higher than previous methods, Pennsylvania State University researchers have found.

The process is not yet commercially viable.

Sun-Seeking Robot Bound for Arctic

April 5, 2001

A sun-seeking robot created at Carnegie Mellon University will be tested for two weeks starting July 10 on Devon Island above the Arctic Circle in Nunavut, Canada, “the closest thing we have to Mars on Earth.”

The experimental Hyperion robot prototype is part of a $1 million NASA project to develop a Mars robot that seeks sunlight that feeds a solar panel on its back.

Sunlight to Fuel Hydrogen Future

December 9, 2004

The photovoltaic cell is old news: the latest way to exploit the sun is through tiny materials that can directly convert sunlight into large amounts of hydrogen.

Hydrogen Solar of Guilford, England, and Altair Nanotechnologies are building a hydrogen-generation system that captures sunlight and uses the energy to break water molecules into hydrogen and oxygen. The company’s current project is a fuel station in Las Vegas that will soon… read more

Sun’s properties not ‘fine-tuned’ for life

May 23, 2008

There’s nothing special about the Sun that makes it more likely than other stars to host life, a new study by Australian National University scientists shows. The finding adds weight to the idea that alien life should be common throughout the universe.

They suggest that there are probably no special attributes that a star requires to have a habitable planet, other than the obvious one — the planet must… read more
