World’s communications network due an energy diet

January 13, 2010

The Internet and other communications networks could use one-ten-thousandth of the energy that they do today if smarter data-coding techniques were used to move information around, say Bell Labs researchers, who have launched a consortium of networking and computing firms called Green Touch that is committed to developing new power-saving technologies.

World’s business servers process 9.57 zettabyes a year

May 10, 2011

The annual amount of business-related information processed by the world’s computer servers is 9.57 zettabytes (9.57×10^21 bytes) per year, scientists at the University of California, San Diego have estimated.

This is the digital equivalent of a 5.6-billion-mile-high stack of books from Earth to Neptune and back to Earth, repeated about 20 times a year. The report complements an earlier report on information consumption, which

World’s Best Microscope Can Produce Images Less Than Diameter Of Single Hydrogen Atom

January 24, 2008

TEAM 0.5, the world’s most powerful transmission electron microscope — capable of producing images with half‑angstrom resolution, less than the diameter of a single hydrogen atom — has been installed at the Department of Energy’s National Center for Electron Microscopy at Lawrence Berkeley National Laboratory.

World’s Best Medical Care?

August 13, 2007

Many Americans are under the delusion that we have “the best health care system in the world,” as President Bush sees it.

That may be true at many top medical centers. But the disturbing truth is that this country lags well behind other advanced nations in delivering timely and effective care.

World Wide Wellness: Online Database Keeps Tabs on Emerging Health Threats

July 9, 2008

Researchers at Children’s Hospital Boston and Harvard Medical School have developed “HealthMap,” an automated data-mining project that searches web-accessible information sources to track emerging health threats worldwide.

HealthMap can often detect potential disease outbreaks in local pockets before health agencies such as the World Health Organization and the U.S. Centers for Disease Control and Prevention (CDC) realize they’re threats.

It collects an average of 300 reports per day… read more

World stocks fell Friday after credit downgrades slapped on Spanish banks unnerved investors already worried about the stability of the 17-country euro currency union.

Political turmoil in Greece has increased the likelihood that it could leave the 17-country monetary union, a move that could have ripple effects throughout Europe and the world’s financial markets.

Markets were jolted by Moody’s downgrade Thursday of 16 Spanish banks, said Jackson Wong,… read more

World record in data transmission: 26 terabits per second on a single laser beam

May 24, 2011

Scientists at Karlsruhe Institute of Technology (KIT) have succeeded in encoding data at a rate of 26 terabits per second on a single laser beam, transmitting over a distance of 50 km.

The team beat its own data rate record of 10 terabits per second (10,000 billion bits per second) set in 2010.

With their new optoelectric decoding method, the high data rate is then broken… read more

Researchers of the Fraunhofer Institute for Applied Solid State Physics and the Karlsruhe Institute for Technology have achieved wireless transmission of 40 Gbit/s over a distance of one kilometer, a new world record.

The technology may help provide future broadband access to the Internet in rural areas and places which are difficult to access.

Using a high frequency range between 200 and 280 GHz… read more

World record data density for ferroelectric recording

August 18, 2010

Scientists at Tohoku University in Japan have recorded data at a density of 4 trillion bits per square inch,  a world record for the experimental ferroelectric data storage method, and about eight times the density of today’s most advanced magnetic hard-disk drives.

The data-recording device uses a tiny cantilever tip that rides in contact with the surface of a ferroelectric material. To write data, an electric pulse is sent… read more

World first trial grows blood vessels from patient’s own skin

November 17, 2005

Scientists have successfully implanted blood vessels grown entirely from a patient’s own cells.

The veins were created in a laboratory by scientists at Cytograft Tissue Engineering before being transplanted into patients undergoing kidney dialysis to test whether they could withstand high blood pressures.

The team is now about to embark on an unprecedented trial at Papworth hospital in Cambridge, which will see lab-grown blood vessels used in heart… read more

World Energy Outlook 2011

Without a bold change of policy direction, the world will lock itself into an insecure, inefficient and high-carbon energy system, the International Energy Agency warned in the 2011 edition of the World Energy Outlook (WEO).

  • The average oil price remains high, approaching $120/barrel (in year-2010 dollars) in 2035.
  • Oil demand rises from 87 million barrels per day (mb/d) in 2010 to 99 mb/d in 2035,
