Natural light 'to reinvent bulbs'



A light source that could put the traditional light bulb in the shade has been invented by US scientists.

The organic light-emitting diode (OLED) emits a brilliant white light when attached to an electricity supply.

The material, described in the journal Nature, can be printed in wafer thin sheets that could transform walls, ceilings or even furniture into lights.

The OLEDs do not heat up like today's light bulbs and so are far more energy efficient and should last longer.

They also produce a light that is more akin to natural daylight than traditional bulbs.

"We're hoping that this will lead to significantly longer device lifetimes in addition to higher efficiency," said Professor Mark Thompson of the University of Southern California, one of the authors of the paper.

Proving How the Universe Was Born

Physicists announced Thursday that they now have the smoking gun that shows the universe went through extremely rapid expansion in the moments after the big bang, growing from the size of a marble to a volume larger than all of observable space in less than a trillion-trillionth of a second.

The discovery -- which involves an analysis of variations in the brightness of microwave radiation -- is the first direct evidence to support the two-decade-old theory that the universe went through what is called inflation.

It also helps explain how matter eventually clumped together into planets, stars and galaxies in a universe that began as a remarkably smooth, super-hot soup.

"It's giving us our first clues about how inflation took place," said Michael Turner, assistant director for mathematics and physical sciences at the National Science Foundation. "This is absolutely amazing."

Brian Greene, a Columbia University physicist, said: "The observations are spectacular and the conclusions are stunning."

Researchers found the evidence for inflation by looking at a faint glow that permeates the universe. That glow, known as the cosmic microwave background, was produced when the universe was about 300,000 years old -- long after inflation had done its work.

Honda Accord ADAS auto-pilot system takes the reins

Posted Jan 30th 2006 4:35PM by Paul Miller
Filed under: Transportation
We've heard of radar assisted cruise control, that has certain luxury cars running at set speeds on the highway, but slows them down or speeds them up when they get too close to a car in front or behind. Well now Honda UK is taking it to another level with their Advanced Driver Assist System (ADAS) that not only regulates your speed, but manages the turning, allowing you a full auto-pilot system for your Accord when you're out on the freeway. The Adaptive Cruise Control is your regular radar variety, but the Lane Keep Assist System keeps you headed in the right direction by using a camera on the rear-view mirror to watch the white lines and turn accordingly. Honda was quick to point out that their system isn't exactly set up for you to take a nap, since the ADAS system will beep every 10 seconds to make sure you're paying attention, requiring you to touch the steering wheel to inform the car you're still in charge, but we're sure someone is going manage an accident and an ensuing lawsuit or three out of this "convenience".

China to build world`s first "artificial sun" experimental device

HEFEI, 01/21 - A full superconducting experimental Tokamak fusion device, which aims to generate infinite, clean nuclear-fusion-based energy, will be built in March or April in Hefei, capital city of east China`s Anhui Province.

Experiments with the advanced new device will start in July or August. If the experiments prove successful, China will become the first country in the world to build a full superconducting experimental Tokamak fusion device, nicknamed "artificial sun", experts here said.

The project, dubbed EAST (experimental advanced superconducting Tokamak), is being undertaken by the Hefei-based Institute of Plasma Physics under the Chinese Academy of Sciences. It will require a total investment of nearly 300 million yuan (37 million U.S. dollars), only one fifteenth to one twentieth the cost of similar devices being developed in the other parts of the world.

The new device will be an upgrade of China`s first superconducting Tokamak device, dubbed HT-7, which was also built by the plasma physics institute, in partnership with Russia, in the early 1990s. HT-7 made China the fourth country in the world, after Russia, France and Japan, to have such a device.

New Horizons will study Pluto and Kuiper Belt

CAPE CANAVERAL — A piano-sized space probe neared the end of its countdown Tuesday for a mission to Pluto, the solar system's last unexplored planet, and to study a mysterious zone of icy objects at the outer edges of the planetary system.

Even though the scheduled afternoon liftoff was intended to make New Horizons the fastest spacecraft ever launched, the distance involved means scientists won't be able to receive data on Pluto until at least July 2015, the earliest date the mission is expected to arrive.

"To make a decision to work in the field of space science is almost the ultimate in delayed gratification," NASA administrator Michael Griffin said at a news conference Tuesday.

A successful journey to Pluto would complete an exploration of the planets started by NASA in the early 1960s with unmanned missions to observe Mars, Mercury and Venus.

"What we know about Pluto today could fit on the back of a postage stamp," Colleen Hartman, a deputy associate administrator at NASA, said earlier. "The textbooks will be rewritten after this mission is completed."

Google and Yahoo tune into television

Two ascending Internet giants, Google and Yahoo, were planning to make plain Friday that they intend to move aggressively beyond the Internet browser and onto the television screen.

The two companies, already the most popular services for searching and organizing the vast information on the Web, want to perform the same function for television, which will increasingly be delivered over the Internet.

Indeed, much of the innovation at the Consumer Electronics Show in Las Vegas, where top executives of both companies were to speak late Friday, revolves around video gadgets of all sizes that connect online to new programming services.

Both Yahoo and Google have emerged as potent threats to television networks because they are drawing ad dollars to their existing sites.

Vote for seven wonders

The Acropolis in Athens made it, as did Angkor Wat temple in Cambodia, China's Great Wall, the Colosseum in Rome, the Inca temple of Machu Picchu in Peru, Stonehenge and the Moai - the Easter Island statues.

Less immediately obvious choices in a final shortlist of 21 contenders for the New Seven Wonders of the World, announced in Switzerland yesterday, included the Kremlin in Moscow, the Eiffel Tower and the Statue of Liberty.

New Space Race: Make Extraterrestrial Travel Cheap And Safe For Ordinary People…

A plan to build the world’s first airport for launching commercial spacecraft in New Mexico is the latest development in the new space race, a race among private companies and billionaire entrepreneurs to carry paying passengers into space and to kick-start a new industry, astro tourism.

The man who is leading the race may not be familiar to you, but to astronauts, pilots, and aeronautical engineers – basically to anyone who knows anything about aircraft design – Burt Rutan is a legend, an aeronautical engineer whose latest aircraft is the world’s first private spaceship. As he told 60 Minutes correspondent Ed Bradley when he first met him a little over a year ago, if his idea flies, someday space travel may be cheap enough and safe enough for ordinary people to go where only astronauts have gone before.

More Rings Are Found Around Planet Uranus

LOS ANGELES - Astronomers aided by the Hubble Space Telescope have spied two more rings encircling Uranus, the first additions to the planet's ring system in nearly two decades.

The faint, dusty rings orbit outside of Uranus' previously known rings, but within the orbits of its large moons, said Mark Showalter, an astronomer at the SETI Institute in Mountain View, Calif., who made the discovery.

Yahoo! plans to shoot Skype with Messenger

Internet media giant Yahoo! has fired the first salvo in a pricing war with Skype with plans to introduce a new internet voice service within days.

Yahoo! is releasing an upgrade to its popular Messenger text, voice and video communications software with the addition of a feature that's familiar to Skype's 68million worldwide users.

"Phone out" will let people make calls from computers to regular telephones while "Phone in" will let computer users receive telephone calls. The service mirror's Skype's equivalent service, named "Skype in" and "Skype out."

Yahoo! said it would undercut Skype's pricing plans for the telephone services, charging just 1¢per minute to people calling the US from countries such as Russia. It will charge 2¢ a minute to call 30 other countries, including Australia, China, France, Germany, Italy, Japan and Korea.

A Yahoo! spokeswoman said it would make the Yahoo! Messenger service available in 180countries, with downloads available from http://voice.yahoo.com/, although as of late on Friday the site was yet to go live.

Google: Ten Golden Rules


Issues 2006 - At google, we think business guru Peter Drucker well understood how to manage the new breed of "knowledge workers." After all, Drucker invented the term in 1959. He says knowledge workers believe they are paid to be effective, not to work 9 to 5, and that smart businesses will "strip away everything that gets in their knowledge workers' way." Those that succeed will attract the best performers, securing "the single biggest factor for competitive advantage in the next 25 years."

At Google, we seek that advantage. The ongoing debate about whether big corporations are mismanaging knowledge workers is one we take very seriously, because those who don't get it right will be gone. We've drawn on good ideas we've seen elsewhere and come up with a few of our own. What follows are seven key principles we use to make knowledge workers most effective. As in most technology companies, many of our employees are engineers, so we will focus on that particular group, but many of the policies apply to all sorts of knowledge workers.

New entry in orbital launch business ready for first flight

EL SEGUNDO, Calif. - A newly developed rocket designed to break into the orbital launch business with low-cost service waited on a Pacific atoll Friday to make its maiden flight.

The Falcon 1 had been scheduled for launch Friday from a pad on Kwajalein Atoll in the Marshall Islands but the launch was bumped back to 1 p.m. PST Saturday because of preparations for a missile defense test launch, said El Segundo-based rocket builder SpaceX.

The rocket's payload is a satellite for the Defense Advanced Research Projects Agency and the Air Force Academy. FalconSat-2 will measure space plasma phenomena, which can impair space-based communications.

The Falcon 1 rocket is the first in what is intended to be a family of launch vehicles from SpaceX, the latest enterprise of Elon Musk, whose previous endeavors include PayPal, the online payment service now owned by eBay.

Ariane rocket launch breaks payload record

Europe's most powerful rocket blasted-off from Kourou in French Guiana on Wednesday night, carrying more than eight tonnes into orbit.

The Ariane 5 ECA launcher lifted off at 2346 GMT carrying two large telecommunications satellites. The launch was initially scheduled for 24 June 2005 but was postponed several times for technical reasons. Most recently, on 12 November, the launch was delayed following of an undisclosed technical problem with the launch platform.

The heavy-lift booster has only flown twice before. During its maiden flight in 2002 it veered off course and had to be destroyed remotely. So mission officials were eager to ensure the third flight was a success. The two telecommunications satellites it carried into space were its heaviest payload yet.

European Space Agency Launches Venus Probe

DARMSTADT, Germany Nov 9, 2005 — A European spacecraft left Earth orbit Wednesday on a five-month, 220 million-mile journey to Venus, an exploratory mission that could help spur a new space race.

The European Space Agency said the unmanned Venus Express lifted off from the Baikonur cosmodrome in Kazakhstan, and mission control in Darmstadt activated the probe's instruments and immediately picked up a signal to hearty applause in the observation room.

The Europeans then received another signal a congratulatory note from the Pasadena, Calif.,-based Planetary Society, which had monitored the launch from NASA's Jet Propulsion Lab.

The brightest stars may owe their origin to black holes


Astronomers at the Chandra X-ray Observatory are agog with findings that may very well trash traditional theories and view the bleak and enigmatic black holes of the Milky Way as originators of new stars. While older theories have held that black holes are the galaxy's destructive forces, these scientists believe that the evidence lies in disks of gas inhabit the vicinity of the black holes to support the new ”star-spawning” theory.

The enigma that surrounds the black holes has spurred numerous science fiction space adventures with the shrunken star remnant's invisible but violent pull even dragging light out of shape into its mysterious vortex. The study that was conducted by the University of Leicester's Sergei Nayakshin and Max Planck Institute's Rashid Sunyaev dwelled into the possibility of black holes playing constructive roles in the galaxies. The spiral Milky Way that supports the earth's solar system on one of its several arms radiating from its core also contains a black hole at its center surrounded by a cluster of stars.
