i had to drop some friends due to security concerns = (i am now a bot, unused accounts, and other useless lurker).... if you were kicked from my lj and give a shit (ie, "oooooooohnoez i am not a bot, a unused account or a useless lurker and i give a rats ass about db's useless blog, please re friend me!")
oh and i have added new friends! welcome!
i will follow this with a quick friends only post, as those seeing the next will know (its all good) |

| Scientists build robot that can replicate itself |
[Jun. 23rd, 2008|03:58 pm] |
FRAMINGHAM, 20 JUNE 2008 - English researchers have developed a robot that can not only create 3-D replicas of objects like shoes and door handles - it also can replicate itself.
Scientists from the University of Bath in England unveiled an open-source machine that acts like a three-dimensional printer. Instead of printing out documents or pictures on paper, this printer uses blueprints to produce 3-D plastic objects.
The machine has been dubbed RepRap, which is short for replicating rapid-prototyper.
The goal is to eventually build a robot that can produce individual processors and circuit boards so people can build their own computers, according to Zack Smith, director of the RepRap Research Foundation.
"It's a printing press for the digital age," Smith told Computerworld. "The goal is to have one on everyone's desk. If it could build circuit boards, someone could design and build their own at home. Open-source electronics is a movement that's really taking hold."
While 3D printers have been commercially available for about 25 years, RepRap is the first that can essentially create its own structural parts, said team member, Vik Olliver, in a written statement.
Smith explained that unlike a regular printer that uses ink, RepRap heats up plastic and then squeezes it out into a line. The lines are built up into usable forms as they solidify. So far, the robot has made everyday plastic objects, like door handles, sandals and coat hooks. The machine has also successfully copied all of its own structural pieces.
For a full replication of all its own parts, Smith said that might be as far away as 20 years down the road. "Being able to replicate a computer chip would take a whole lot of precision," he added. "For me, the exciting part is we're building a tool that can build other things." |

Robofish, developed at the UW.
In the world of underwater robots, this is a team of pioneers. While most ocean robots require periodic communication with scientist or satellite intermediaries to share information, these can work cooperatively communicating only with each other.

| Scientists witness start of star's explosive death |

WASHINGTON - In a stroke of cosmic luck, astronomers for the first time witnessed the start of one of the universe's most fiery events: the end of a star's life as it exploded into a supernova.
On Jan. 9, astronomers used a NASA X-ray satellite to spy on a star already well into its death throes, when another star in the same galaxy started to explode. The outburst was 100 billion times brighter than Earth's sun. The scientists were able to get several ground-based telescopes to join in the early viewing and the first results were published in Thursday's issue of the journal Nature.
"A star exploded right before my eyes," lead author Alicia Soderberg, an astrophysics researcher at Princeton University, said Wednesday in a teleconference.
She likened it to "winning the astronomy lottery. We caught the whole thing from start-to-finish on tape."

| Star explodes halfway across universe |
[Mar. 24th, 2008|10:38 pm] |
By SETH BORENSTEIN, AP Science WriterFri Mar 21, 3:01 PM ET
The explosion of a star halfway across the universe was so huge it set a record for the most distant object that could be seen on Earth by the naked eye.
The aging star, in a previously unknown galaxy, exploded in a gamma ray burst 7.5 billion light years away, its light finally reaching Earth early Wednesday.
The gamma rays were detected by NASA's Swift satellite at 2:12 a.m. "We'd never seen one before so bright and at such a distance," NASA's Neil Gehrels said. It was bright enough to be seen with the naked eye.
However, NASA has no reports that any skywatchers spotted the burst, which lasted less than an hour. Telescopic measurements show that the burst — which occurred when the universe was about half its current age — was bright enough to be seen without a telescope.
"Someone would have had to run out and look at it with a naked eye, but didn't," said Gehrels, chief of NASA's astroparticles physics lab at Goddard Space Flight Center in Greenbelt, Md.
The starburst would have appeared as bright as some of the stars in the handle of the Little Dipper constellation, said Penn State University astronomer David Burrows. How it looked wasn't remarkable, but the distance traveled was.
The 7.5 billion light years away far eclipses the previous naked eye record of 2.5 million light years. One light year is 5.9 trillion miles.
"This is roughly halfway to the edge of the universe," Burrows said.
Before it exploded, the star was about 40 times bigger than our sun. The explosion vaporized any planet nearby, Gehrels said. |
