The hunt for blood substances that slow brain aging

September 2, 2011

Stanford University School of Medicine scientists have found substances in the blood of old mice that make young brains act older.

The researchers connected the circulatory systems of pairs of old and young mice via a surgical procedure, which produced brain changes in  areas critical to memory and learning (like the hippocampus) in both type of mice: the older… read more

The Hypermedia Hazard

October 25, 2001

Media and political institutions responsible for providing clarity and coherent information appear to be unraveling under the stress of coping with terrorist attacks, especially the anthrax problems, casualties and resulting hysteria.

The iCub robot learns archery

September 30, 2010

iCub robot (Dr. Petar Kormushev)

The humanoid robot iCub has learned a new skill: archery. After being taught how to hold a bow and shoot an arrow, it learned for itself how to improve its aim, and was so successful it could hit a bullseye after only eight trials.

The algorithm used to teach iCub, developed by Dr. Petar Kormushev and colleagues of the Italian Institute of Technology, is called the Augmented Reward Chained Regression… read more

The immune system may protect against Alzheimer’s changes in humans

May 29, 2012


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.

Researchers at the Peninsula College of Medicine and Dentistry, University of Exeter with colleagues in the National Institute on Aging in the USA and in Italy screened the… read more

The impact of its environment on a quantum computer

April 15, 2005

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.

The Impact of Video and Rich Media on the Internet — A ‘zettabyte’ by 2015?

January 30, 2008

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.

“The U.S. Internet of 2015 will be… read more

The Importance of Being Frightened

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 Increase in Chip Speed Is Accelerating, Not Slowing

February 4, 2002

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

The incredible shrinking tabletop particle accelerator

Coming: "seeing the atomic structure of single protein molecules in a living sample"
July 1, 2013


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

The Infinite Library

April 21, 2005

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?

The Intelligent Universe author James Gardner to appear on Coast To Coast AM show

February 20, 2007

James Gardner, author of the recently published book, The Intelligent Universe, will appear on the national Coast To Coast AM radio show on Tuesday night Feb. 20 to discuss the meaning of the intelligent universe, the process of cosmic evolution, and the impact of the discovery of ETs on religion.

The Internet gets physical

December 19, 2011

The Internet of Things or the Industrial Internet is here. Across many industries, products and practices are being transformed by communicating sensors and computing intelligence.

Examples: Nest Labs (a digital thermostat), General Electric (smart hospital room), IBM (2,000 projects worldwide that fit in the Smarter Planet category).

“We’re going to put the digital ‘smarts’ into everything,” said Edward D. Lazowska, a computer scientist at the University of Washington.… read more

The Internet IS a Series of Tubes: Real-Time Mapping of the London Underground

June 22, 2010

London Train Map

The live train map for the London Underground is a nearly real-time Google Maps mashup that shows data on every train in the London Underground as they move about their subterranean travels.

The Internet Just Ran Out of Numbers

February 7, 2011

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

The Internet Knows What You’ll Do Next

July 4, 2006

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
