Scientists find key to avian flu in humans

January 7, 2008

MIT researchers have uncovered a critical difference between flu viruses that infect birds and humans–it can bind to one specific shape of receptor on the surface of human respiratory cells.

The discovery could help scientists monitor the evolution of avian flu strains and aid in the development of vaccines against a deadly flu pandemic.

Fujitsu Debuts Bendable Electronic Paper

July 18, 2005

Fujitsu has developed the world’s first film substrate-based bendable color electronic paper with an image memory function.

The new electronic paper features vivid color images that are unaffected even when the screen is bent, and features an image memory function that enables continuous display of the same image without the need for electricity. The thin and flexible electronic paper uses very low power to change screen images, making it… read more

WHITE PAPER GETS EXPERTS WONDERING ABOUT NANO REALITY AND HYPE

July 30, 2002

A white paper says nanotechnology will affect a wide range of industries and there are promising investments to be made, but warns about the hype.

Acid Blockers Linked to Pneumonia Risk

May 27, 2009

Use of proton pump inhibitors and other acid-suppressing drugs was associated with a 30% increased risk of hospital-acquired pneumonia in a study by researcher Shoshana J. Herzig, MD, of Beth Israel Deaconess Medical Center and Harvard School of Medicine.

Herzig and colleagues estimate that 180,000 cases of hospital-acquired pneumonia and 33,000 deaths each year may be due to their use.

Reversal Of Alzheimer’s Symptoms Within Minutes In Human Study

January 10, 2008

University of California, Los Angeles and University of Southern California researchers have found a “dramatic and unprecedented” therapeutic effect in an Alzheimer’s patient: improvement within minutes, following delivery of perispinal etanercept to reduce elevanted tumor necrosis factor-alpha(TNF), a component of the brain’s immune system.

Scientists urge caution in responding to the news that a drug commonly used to treat arthritis caused a dramatic and rapid improvement in patients with… read more

New method of growing nanotube circuits may allow for faster processors

August 1, 2005

A new semiconductor fabrication method creates nanoscale circuits by dipping semiconductor chips into liquid suspensions of carbon nanotubes, rather than growing the nanotubes directly on the circuit.

Previously, most nanotube circuits have been made by growing each nanotube on the surface of a chip, using chemical vapor deposition. Unfortunately, this method often results in a circuit comprised of both types of nanotubes, metallic and semiconducting.

Furthermore, the growth… read more

Cities Die. Should New York Be the First to Clone Itself?

August 20, 2002

New York City is creating of an immensely detailed, three-dimensional, interactive, constantly updated map of the city.

“NYCMap” will be stored on remote servers in case something more terrible than 9-11 hits.

Models’ Projections for Flu Miss Mark by Wide Margin

June 2, 2009

On May 15, the Centers for Disease Control and Prevention estimated that there were “upwards of 100,000″ cases in the U.S., compared to estimates of 2,000 to 2,500 by two rival supercomputer teams.

Food from cloned animals deemed safe in US

January 16, 2008

The FDA has announced that food from cloned animals and their offspring is safe for consumption.

However, the US Department of Agriculture urged food producers to preserve a voluntary moratorium on marketing food from cloned animals until regulators can determine how best to introduce them into the US meat
and dairy market.

Medics braced for fresh superbug

August 10, 2005

Nature reports that medical experts are concerned that if antibiotic overuse in hospitals is not curbed, drug-resistant strains of the Acinetobacter baumannii bacterium could become a serious killer in intensive-care wards worldwide.

“We have calculated that 40% of our patients who become infected with A. baumannii die because of it,” says Yehuda Carmeli, an infectious-disease physician at the Tel Aviv Sourasky Medical Center in Israel.

Controlling the magnetic properties of graphene

April 15, 2011

Graphene Magnet

Researchers at the University of Maryland have discovered a way to control magnetic properties of graphene that could lead to new applications in magnetic storage and magnetic random access memory.

The researchers found that missing atoms in graphene, called vacancies, act as tiny magnets. Vacancies have magnetic moments that interact strongly with the electrons in graphene, which carry electrical currents. This gives rise to a… read more

Nanotech’s grand challenge: energy self-sufficiency, says von Ehr

September 11, 2002

“Nanotechnology needs a ‘grand challenge’ project, and energy self-sufficiency is one that would pay huge benefits to both the USA and the world,” says James R. von Ehr II, President & CEO of Zyvex Corp.

He presented this idea at the recent White House Economic Forum, which brought together leaders from various sectors to discuss the fundamentals of the economy and the President’s agenda to increase economic growth for… read more

Roll-Up Solar Panels

June 8, 2009

Xunlight has developed a way to make large, flexible solar panels: a roll-to-roll manufacturing technique forms thin-film amorphous silicon solar cells on thin sheets of stainless steel.

Such systems could be incorporated more easily into irregular roof designs, or rolled up and carried in a backpack.

Two AI Pioneers. Two Bizarre Suicides. What Really Happened?

January 21, 2008

Chris McKinstry created a database called Mindpixel. Push Singh created a database called Open Mind Common Sense.

Both believed their programs could be used to develop machine intelligence, using massive amounts of commonsense data. Both committed suicide.

Intel Says Forget Megahertz And Gigahertz

August 24, 2005

Intel Chief Executive Paul Otellini says megahertz and gigahertz is out, and “performance per watt” is in.

The new combined measurement is more relevant to smaller, flexible devices, like notebook computers, portable media players and smart phones, because heat and power consumption have a direct impact on performance and battery life.

Using Intel’s “dual core” technology, in which computations are done within two “brains” on a single chip,… read more
