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’

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.

Xerox Inkless Printer

February 26, 2007

Xerox is developing a new printing technology which does not require ink of any kind. The new technology includes reusable paper that can be printed and erased dozens of times and has the potential to revolutionize printing.

Xerox hopes plastic ink leads to printed chips

April 19, 2004

Xerox researchers have discovered a way to print plastic transistors using a semiconductive ink at room temperature, paving the way for flexible displays and low-cost RFID (radio frequency identification) chips.

The new technique builds on a polythiophene semiconductor, an organic compound that resists degradation in open air better than other semiconductor liquids and also exhibits self-assembling properties.

The researchers found a way to process this material to form… read more

Xerox Develops New Way to Print Invisible Ink

May 31, 2007

Xerox scientists have perfected a new method for printing hidden fluorescent wording using standard digital printing equipment, allowing for an additional layer of security to commonly printed materials such as checks, tickets, coupons, and other high-value documents.

Xerox Claims Printable Electronics Breakthrough

October 30, 2009

Xerox has announced a new silver ink that is apparently a breakthrough in printable electronics.

The possibilities range from printing on flexible plastic, paper and cardboard, and fabric, to printing RFID tags on almost anything.

Xbox 360 Project Natal: Full-Body Motion Control One-Ups the Wii

June 2, 2009

Microsoft’s Project Natal, a bar that sits above or below your TV, lets you control games just by moving around, using a camera, sensors and a microphone.

It lets you move through menus by swiping your hands back and forth. The camera allows for facial and voice recognition and will recognize your face and sign you in automatically.

It also tracks your full body movement in 3-D, while… read more

X-ray nanocrystallography captures 3D images of biomolecules

How to shoot 3D movies of biomolecules at atomic resolution
July 27, 2012


By outrunning a X-ray laser’s path of destruction, an international research team has created 3D images of fragile but biologically important molecules inside protein nanocrystals.

Using the Linac Coherence Light Source (LCLS), a powerful at the SLAC National Accelerator Laboratory in Menlo Park, Calif., the scientists fired femtosecond (one quadrillionth of a second) bursts of light at a stream of tumbling molecules, obliterating them as they passed — but… read more
