Cutting Edge

Outgoing space station commander Frank De Winne, cosmonaut Roman Romanenko, and Canadian astronaut Robert Thirsk strapped into a Russian Soyuz capsule, undocked and fell back to Earth on Tuesday, braving icy weather in Kazakhstan to close out a 188-day stay in space.

Descending under a large orange-and-white parachute, Soyuz TMA-15 spacecraft made a rocket-assisted touchdown about 50 miles northeast of Arkalyk, Kazakhstan, at 2:15:34 a.m. EST, about three hours and 20 minutes after undocking from the International Space Station.

Recovery forces, including U.S. and Russian flight surgeons, were near the landing site to help the returning … Read more

I can understand why people are so keen to find alien life. It isn't so much a scientific fascination with what might be out there. It's more a pained hope that what is out there might be more enjoyable than what is down here.

So I am wrestled to the ground by a certain sympathy for Brad Niesluchowski.

According to the Arizona Republic, Niesluchowski was asked to resign after allegedly using his position at the Higley Unified School District to exercise his own (and our) need for an alien encounter.

This was not a case of uploading pictures … Read more

The Large Hadron Collider (LHC) is one of the most ambitious experiments of all time and following a year of shutdown, it's finally started to do its business again. So we thought we'd have a chat to someone directly involved in the experiments to get a sense of what it's like to work in geek heaven.

Paul Jackson is a particle physicist from SLAC and Stanford University, based at CERN. He's working on the Atlas experiment, looking for the Higgs boson--the so-called "God particle." Read on to find out whether he's about … Read more

The recently restarted Large Hadron Collider has become the world's most powerful particle accelerator, after setting a new record for beam intensity.

Scientists working at the particle collider successfully accelerated a beam of protons up to 1.18 tera-electron-volts (TeV) late on Sunday night, beating the previous record of 0.98 TeV, CERN has announced. In the early hours of Monday morning, both the clockwise and the anticlockwise beams were accelerated to 1.18 TeV, giving the protons a speed of approximately 0.9997 times the speed of light.

The previous record for beam intensity was 0.98 TeV, … Read more

SAN FRANCISCO--About 30 people listened intently on a recent Thursday night to short presentations on linear algebra and beer brewing, watched a demo of an iPhone cyberspace shooter game, and learned how to make a light staff (acrylic rod, LED, resistor, tape, no soldering required).

For the last talk, a speaker billed as "Dr. Baron Mikheil von Burstein, esq." explained how to pull off his interactive public art specialty--swings that hang in the aisles on the underground trains in the Bay Area Rapid Transit (BART) system.

"I installed it publicly, illegally and got away with it," … Read more

KENNEDY SPACE CENTER, Fla.--The shuttle Atlantis dropped out of a crystal clear Florida sky and glided to a "picture-perfect" landing at the Kennedy Space Center Friday to close out a successful 11-day space station mission, bringing astronaut Nicole Stott back to Earth after 91 days in space.

With commander Charles Hobaugh at the controls, Atlantis executed a sweeping right overhead turn to line up on runway 33, pilot Barry Wilmore deployed the ship's landing gear and the shuttle settled to a tire-smoking touchdown at 9:44:23 a.m. EST.

"Houston, Atlantis, wheels stopped," … Read more

The world's largest particle accelerator has performed its first collisions, and its first beam acceleration.

Progress on the giant experiment has been rapid in the four days since the Large Hadron Collider (LHC) was restarted, CERN director of communications James Gillies told ZDNet UK on Tuesday.

"These collisions are the first in the LHC at all," said Gillies. "We've been going into new territory. It's been going quite remarkably fast."

Gillies told ZDNet UK that not only had scientists recorded the first collisions of protons on Monday, but that overnight one of the … Read more

Global company IBM seems to have found a way for its employees to get past language barriers and communicate.

IBM employees are currently using text translation software that can instantly convert documents, Web pages, and even instant messages between English and 11 other languages. The software, christened "n.Fluent," is being "crowdsourced" or tested among IBM's 400,000 employees across 170 countries.

As IBMers use n.Fluent, the software learns from its mistakes and improves itself. As the entire company potentially taps into n.Fluent, volunteers within IBM refine each translated word for greater accuracy. … Read more

JOHNSON SPACE CENTER, Houston--Astronaut Randy Bresnik carried out a spacewalk Saturday awaiting word of the birth of his second child. Responding to a wake-up call from Houston early Sunday, he delivered the news that his wife, Rebecca, had given birth, saying "good morning, Houston. Good morning, Rebecca, good morning, Wyatt, and good morning to our little girl."

"I just wanted to take this opportunity to report some good news," he said later in the morning. "At 11:04 last night, Abigail Mae Bresnik joined the NASA family and momma and baby are doing very well. … Read more
