Yacht voyage yields array of new genes

March 14, 2007

A yacht voyage that genome pioneer Craig Venter took around the world has turned up a startling array of new genes and new gene families.

They have found genes that help microbes use the sun’s energy in new ways, genes that help them use nitrogen, and genes that protect organisms from ultraviolet light, and have identified more than 6 million new proteins.

Y-shaped nanotubes are ready-made transistors

August 16, 2005

Y-shaped carbon nanotubes grown with iron-titanium particles are easily made and act as remarkably efficient electronic transistors that are 100 times smaller than the transistors used in today’s microprocessors.

So they could be used to create microchips several orders of magnitude more powerful than the ones used in computers today, with no increase in chip size. The Y-shaped nanotubes measure just tens of nanometers in size. Eventually, they could… read more

XPRIZE has announced the launch of the $2 million Wendy Schmidt Ocean Health XPRIZE. It aims to spur global innovators to develop accurate and affordable ocean pH sensors that will ultimately transform our understanding of ocean acidification, one of the gravest problems associated with the rise in atmospheric carbon dioxide (CO2).

“Just as we have sensors to monitor our body’s vital signs, we… read more

Astronomers have probed closer than ever to a supermassive black hole estimated to have the mass of about 3 to 5 million solar masses, at the core of a distant active galaxy.

XML-based ‘Flare’ programming language project launched

July 24, 2001

The Singularity Institute for Artificial Intelligence has launched the Flare programming language project, headed by programmer Dmitriy Myshkin.

Flare is proposed as a fundamentally new programming language expected to be useful for AI research (among other uses). “Program objects and program code can be represented as well-formed XML, enabling a wide variety of new design patterns and language idioms,” says the announcement.

“Current programming… read more

xMax sparks low power wireless revolution

November 7, 2005

xG Technology has demonstrated wireless broadband 1000 times more efficient than WiMax, and claims the technique could also make wireless LANs that will run for years on watch batteries and could allow anyone to set up as a wireless ISP.

XKeyscore: NSA tool collects ‘nearly everything a user does on the Internet’

XKeyscore map

A top secret National Security Agency program allows analysts to search with no prior authorization through vast databases containing emails, online chats and the browsing histories of millions of individuals — its “widest-reaching” system for developing intelligence from the Internet — according to documents provided by whistleblower Edward Snowden, Guardian columnist Glenn Greenwald reported Wednesday.

The latest revelations come as senior intelligence officials… read more

Xerox touts erasable paper, smart documents

May 1, 2008

Xerox has developed paper that can be reused after printed text automatically deletes itself from the paper’s surface within 24 hours.

A single piece of paper can be reused up to 100 times for black and white printing. The paper contains specially coded molecules that create a print after being exposed to ultraviolet light emitted from a thin bar in a printer. The molecule readjusts itself within 24 hours… read more

Xerox Says New Material Will Allow Plastic Transistors

December 3, 2002

Xerox researchers are developing an experimental polymer that can be used to make organic transistors on a plastic substrate and could be easier to manufacture at lower cost.

Xerox Rolls Out Semantics-Based Search

June 21, 2007

Xerox Corp. says its new search engine based on semantics will analyze the meaning behind questions and documents to help researchers find information more quickly.

Xerox reveals transient documents

September 8, 2006

Xerox is developing “transient documents” — reusable paper that allows content to be automatically erased after a period of time, ready for fresh printing.

The paper has a photochromic compound that changes from a clear state to a colored state under ultraviolet light and will fade with time.
