Recent work in mice suggested that the immune system is involved in removing beta-amyloid, the main Alzheimer’s-causing substance in the brain. Researchers have now shown for the first time that this may apply in humans.

Scientists have discovered how the performance of a quantum computer can be affected by its surrounding environment.
The study, published in the latest issue of the journal Science, will help engineers to better understand how to integrate quantum components into a standard office computer – moving us one step closer to a future of quantum computing.
From YouTube, IPTV, and high-definition images, to “cloud computing” and ubiquitous mobile cameras, 3D games, virtual worlds, and photorealistic telepresence, the new wave is swelling into an exaflood of Internet and IP traffic.
Bret Swanson & George Gilder estimate that by 2015, U.S. IP traffic could reach an annual total of one zettabyte (1021 bytes), or one million million billion bytes.

Emotional facial expressions confer a survival advantage, University of Toronto researchers have found, using vision and breathing tests.
A fearful visage improves peripheral vision, speeds up eye movement, and boosts air flow, potentially allowing a person to more quickly sense and respond to danger. Squinty, scrunched-up disgusted faces had the opposite effect, limiting vision and decreasing air flow, ostensibly to keep out substances that might be harmful… read more

The trajectory of desktop PC performance increases of the last two years will not slow in the near future, but actually accelerate, based on an expected announcement by Intel Corp. at the International Solid State Circuits Conference. Intel will present a paper today detailing a portion of a microprocessor chip that has performed at up to 10 gigahertz at room temperature —- the fastest calculating speed yet reported… read more

Physicists at The University of Texas at Austin have built a tabletop particle accelerator that can generate energies and speeds previously reached only by major facilities that are hundreds of meters long and cost hundreds of millions of dollars to build.
“We have accelerated about half a billion electrons to 2 gigaelectronvolts (GeV) over a distance of about 1 inch,” said… read more

Google is converting the full text of millions of library books into searchable Web pages. How will libraries function in 2020 or 2050, once Google or its successors have finished digitizing the world’s printed knowledge?

On February 3, it finally happened: the stash of IPv4 Internet protocol addresses that are used to identify and locate computers connected to the Internet was exhausted.
Fortunately, engineers realized the limitations of IPv4 a long time ago and lined up a successor, called IPv6, in 1998. IPv6 uses 128 bits rather than 32, producing a pool of numbers that is staggeringly huge — some 3.4 x 10 to… read more

Google Trends allows you to check the relative popularity of any search term, to look at how it has changed over the last couple years and to see the cities where the term is most popular.
When this and other new tools get good enough, you can see how the business of marketing may start to change. As soon as a company begins an advertising campaign, it will be… read more

Wireless vehicle networks could make driving safer, more efficient, and less polluting, but the cost of deployment will be significant, MIT Technology Review reports.
This week, officials from the U.S. Department of Transportation in Washington, DC, will see the technology in action, in a demonstration organized by experts from the University of Michigan’s Transportation Research Institute and various communications equipment and car manufacturers.… read more
