Keeping the mind young, strong

April 20, 2006

Nintendo’s Brain Age game celebrates the work of Japanese neuroscientist Ryuta Kawashima by engaging owners in a series of hands-on exercises geared to giving their gray matter a rigorous workout, including daily tests of the current age of their brains.

Nanotechnology may create new organs

July 9, 2003

Scientists have built a minute, functioning vascular system — the branching network of blood vessels which supply nutrients and oxygen to tissues — in a significant step towards building whole organs.

Using living vessels as a guide to model factors such as the angle and size ratio between branching vessels, the networks were etched on to 15 centimetre-wide silicon wafers and the paths were then used as a mould… read more

Why do the majority of people never get cancer?

February 4, 2009

George Klein, Professor Emeritus at the Microbiology and Tumor Biology Center at the Karolinska Institute in Stockholm, Sweden, has presented evidence of several biological cancer resistance mechanisms that some individuals have that seem to prevent them from developing cancer.

Sleights of Mind

August 22, 2007

Some magicians have intuitively mastered some of the lessons being learned in the laboratory about the limits of cognition and attention.

In Las Vegas, cognitive scientists such as Daniel Dennett and magicians like The Amazing Randi compare notes.

‘Cyclic universe’ can explain cosmological constant

May 5, 2006

A cyclic universe, which bounces through a series of big bangs and “big crunches,” could solve the puzzle of our cosmological constant, physicists suggest.

At every big bang, the amount of matter and radiation in the universe is reset, but the cosmological constant is not, Paul Steinhardt at Princeton University and Neil Turok at Cambridge University believe. Instead, the cosmological constant gradually diminishes over many cycles to the small… read more

Electronic Paper

July 18, 2003

Some nanotechnologists say that soon everyone could be reading off electronic paper.

Cutting Coal Use with Sunshine

February 10, 2009
These parabolic mirrors gather heat energy for a 150-megawatt hybrid solar/natural-gas power plant under construction south of Cairo. During the day, solar heat will displace a fraction of the natural gas required to drive the plant

Feeding heat from the sun into coal-fired power stations could turn out to be the cheapest way to simultaneously expand the use of solar energy and trim coal plants’ oversize carbon footprints, says the Electric Power Research Institute.

Aubrey de Grey’s ‘Ending Aging’ book published

September 4, 2007

Aubrey de Grey’s much-anticipated book, Ending Aging: The Rejuvenation Breakthroughs That Could Reverse Human Aging in Our Lifetime, co-authored by Michael Rae, was published today by St. Martin’s Press.

Dr. de Grey believes that the key biomedical technology required to eliminate aging-derived debilitation and death entirely–technology that would not only slow but periodically reverse age-related physiological decay, leaving us biologically young into an indefinite future–is now within… read more

Synthetic biologists reject controversial guidelines

May 24, 2006

Researchers in the new field of synthetic biology have pledged to develop better tools to identify anyone trying to order the DNA needed to make deadly pathogens. But at the Synthetic Biology 2.0 meeting in Berkeley, California, they decided against adopting a controversial code of conduct intended to prevent their technologies being used to make new bioweapons.

Super Soldiers

July 24, 2003

New materials and technologies could boost the mobility and safety of U.S. troops.

Scientists at DuPont are developing ways to manipulate light so soldiers could appear to disappear. EIC Laboratories is working on “electrochromic camouflage” — a chameleon fabric that would change colors instantly to blend in with its surroundings.

The new Institute for Soldier Nanotechnologies at MIT is creating new materials and devices molecule by molecule with… read more

Gadget reads users’ minds from their grip

February 17, 2009

A new “bar of soap” device by MIT researchers can predict what function its user wants from the way it is manipulated, using a three-axis accelerometer to measure its motion in 3D, and 72 sensors across its surface to track the position of the user’s fingers.

Nanoscale Inkjet Printing

September 13, 2007

A new type of inkjet printer has been developed that can precisely print dots of various materials just 250 nanometers in diameter.

The inkjet printer could make it possible to rapidly synthesize complex nanoscale structures out of a broad range of materials for manufacturing novel devices, from plastic electronics and flexible displays to photovoltaic cells and new biomedical sensors.

GNU Radio Opens an Unseen World

June 6, 2006

The Universal Software Radio Peripheral (USRP) allows for building a software-defined general radio that can receive and transmit on any frequency from DC (zero) to 2.9 GHz.

Inventor Matt Ettus paints a picture of radio bringing about a many-to-many revolution, like blogging, but for a wider segment of the world. “It enables everybody to be a broadcaster,” he says.

Student challenges basic ideas of time

August 1, 2003

A bold paper that been published in the August issue of Foundations of Physics Letters seems set to change the way we think about the nature of time and its relationship to motion and classical and quantum mechanics. The work also appears to provide solutions to Zeno’s paradoxes.

In the paper, “Time and Classical and Quantum Mechanics: Indeterminacy vs. Discontinuity”, Peter Lynds argues that “There’s no such thing as… read more

The Health Effects of Social Networking

February 25, 2009

Two British scientists have recently suggested that spending all day, and much of the night networking on a computer might in fact be bad for your body and your brain.

Susan Greenfield, a neuroscientist at the University of Oxford, said her fear is that “these technologies are infantilizing the brain into the state of small children who are attracted by buzzing noises and bright lights, who have a small… read more
