SANYO Breaks Solar Cell Record

May 22, 2009

SANYO Electric has broken its own record for the world’s highest energy conversion efficiency in practical size (100 cm2 or more) crystalline silicon-type solar cells, achieving a efficiency of 23.0% (until now 22.3%) at a research level for its proprietary HIT solar photovoltaic cells.

SARS Virus is Mutating, Fear Doctors

April 18, 2003

“A cluster of SARS patients in Hong Kong with unusual symptoms has prompted concern that the virus causing the disease is mutating….Scientists in Hong Kong are now urgently sequencing key genes from recently isolated coronaviruses to reveal any changes.”

Sasser computer worm wriggles worldwide

May 5, 2004

More than a million computers around the world have been infected by the “Sasser” computer worm or one of its variants.

Sasser does not rely on email to spread and requires no action by users to infect a machine. Each variant of the worm infects computers across a network by exploiting a bug in a part of Microsoft’s Windows XP and Windows 2000 operating systems called the Local Security… read more

Satellite could open door on extra dimension

May 31, 2006

T%here could be several thousand black holes in the solar system, say Duke University researchers, and they may soon be detected.

Their gravity should bend light passing nearby, so that light passing on one side of a black hole should take a different amount of time to go by than light passing on the other side, detectable by interference patterns during gamma-ray bursts.

Satellite quantum communication circles closer

July 30, 2010

A new quantum protocol is the first that promises to work independently of the orientation of spin on pairs of entangled photons shared between a sender and receiver, which will prove vital if quantum communications are ever to be sent via satellites (a spinning satellite’s sense of up and down changes over time, making it harder to interpret a photon’s spin and establish a key).read more

Saudi Arabia unveils grand supercomputer ambitions

September 26, 2008

Saudi Arabia plans to build a petascale supercomputer system in two years that could rank among the 10 most powerful systems in the world, and beyond that, an exascale system (1000 times as fast as petascale).

Code-named Shaheen (Peregrine Falcon), it is being built by IBM, based on the Blue Gene/P System, and will intially run at 222 teraflops. It will be located at King Abdullah University of Science… read more

Savant for a Day

June 23, 2003

Cognitive scientist Allan Snyder has found that 40 percent of test subjects undergoing transcranial magnetic stimulation (TMS) exhibited extraordinary, and newfound, mental skills.

Saving information on a computer boosts human memory resources for new information

The simple act of saving something, such as a file on a computer, may improve our memory for the information we encounter next, according to new research published in Psychological Science, a journal of the Association for Psychological Science. The research suggests that the act of saving helps to free up cognitive resources that can be used to remember new information.

“Our findings show that people are significantly better at… read more

Saving Lives with Living Machines

July 1, 2003

Hybrid devices that are part machine, part living cells offer new hope to patients with kidney problems for whom purely artificial treatments like dialysis aren’t good enough.

A “bioartificial kidney,” being developed by Nephros Therapeutics, is based on a plastic cartridge containing one billion human kidney cells thriving inside 4,000 translucent, hollow, plastic fibers. It is based on a decade of research by University of Michigan internist David Humes.… read more

Saving Lives With Tailor-Made Medication

August 29, 2006

Pharmacogenetics, a clinical discipline in which doctors use high-tech genetic testing to custom-make drugs to patients’ individual needs, will mean that we define smaller and smaller markets for every drug.

Instead of one medication for high blood pressure, a manufacturer will have to produce dozens of variants and combinations.

Saving More Lives by Building a Better Scanner

June 23, 2008

Toshiba’s new Aquilion ONE computed-tomography (CT) scanner could change the way doctors diagnose and treat such illnesses as stroke and heart attack, making many standard tests unnecessary.

The ONE does nearly everything–filming, in high-resolution, dynamic volume imagery, how organs function–in 20 minutes or less, for under $1,000 and with 80 percent fewer x-rays than other CT scanners.

A current CT machine takes pictures of organs by the slice,… read more

Saving Neurons and Memories

July 24, 2007

Harvard and MIT scientists have shown that the SIRT1 gene and resveratrol can protect against neuron degeneration of Alzheimer’s disease and amyotrophic lateral sclerosis in a mouse model.

The Harvard/MIT study could also shed light on the mechanisms behind Alzheimer’s.

Saving Skin

February 12, 2002

Bioengineered skin — grown in the lab using small samples of human cells — offers an alternative to animal testing.
Proponents argue that tissue models provide both ethical and scientific advantages. Scientists don’t have to extrapolate human responses from animal-derived data and test results are easier to reproduce from lab to lab.

While limited, bio-engineered models are finding a niche as tools to screen out drugs likely to fail… read more

Saving the Net: How to Keep the Carriers from Flushing the Net Down the Tubes

November 17, 2005

“Are you ready to see the Net privatized from the bottom to the top? Are you ready to see the Net’s free and open marketplace sucked into a pit of pipes built and fitted by the phone and cable companies and run according to rules lobbied by the carrier and content industries?

“Do you believe a free and open market should be ‘Your choice of walled garden’ or ‘Your… read more

Saving the universe

February 11, 2003

NASA is expected to announce this week that it has proved the existence of “dark energy,” a cosmic force that counteracts gravity and will keep the universe expanding forever. The announcement will effectively demolish the theory that life will be wiped out in a “big crunch” when the universe collapses, and should end decades of academic dispute.

NASA has found a pattern of “hot spots” which proves that the… read more
