Early findings by the U.S. Department of Transportation indicate that drivers were to blame in some sudden-acceleration accidents, according to a Wall Street Journal report citing people familiar with the results.

Preliminary results show some cases of driver error, the Journal reported Wednesday. "The early results suggest that some drivers who said their Toyotas and Lexuses surged out of control were mistakenly flooring the accelerator when they intended to jam on the brakes," the Journal said.

The National Highway Traffic Safety Administration has yet to release the findings and it declined to comment about them, the Journal … Read more

GENEVA--The Large Hadron Collider is a marvel of both brute-force and sophisticated engineering.

To start, look at the mostly circular cavern, 27 kilometers in circumference, that houses the accelerator. It's got an average depth of 100 meters, but in fact it's actually horizontal: its plane is tilted 1.4 percent to keep it as shallow as possible to minimize the expense of digging vertical shafts while placing the cavern in a subterranean sandstone layer.

Tidal forces from the moon cause the Earth's crust to rise about 25cm, an effect that increases the LHC's circumference by 1mm. … Read more

GENEVA--The LHC shows science on an unusually large scale.

Thousands of researchers are involved in each of the Large Hadron Collider's major experiments, and more are there to operate the beam itself. Something like half the world's particle physicists are involved one way or another with the LHC, estimated Maria Isabel Pedraza Morales, a University of Wisconsin physicist who works on the ATLAS experiment.

The accelerator is likely to lead to hundreds of academic papers and doctoral dissertations in coming years. CERN's hallways are teeming with an international mix of senior physicists and young researchers just getting … Read more

GENEVA--There are two kinds of physicists in the world, broadly speaking: those with the equation-covered blackboards, and those with the scales, thermometers, and pressure gauges.

The theoretical physicists have had the upper hand for years, but something new has begun tilting the balance toward the experimentalists: the Large Hadron Collider.

This mammoth, $8 billion particle accelerator is housed in a ring 27km in circumference bored about 100 meters beneath a somewhat pastoral valley west of Geneva and operated by a multinational nuclear physics organization called CERN, which was founded in 1954.

The LHC is now speeding protons nearly to the … Read more

While Apple continues its aggressive campaign to call the future of Flash into doubt, Adobe has released its latest version of the content platform. Adobe Flash 10.1 is now available for Windows, Mac, and Linux.

By some estimates, Flash powers more than three-quarters of the Internet's video and games. Adobe has had release candidates out for months, going through six previous release candidate versions, not to mention multiple beta releases. The most important improvement for Windows users is that the new version offers hardware acceleration, but the feature isn't fully supported yet on Macs. Adobe plans on supporting … Read more

Chrysanth Download Manager is a simple tool that lets you manage your downloads and their respective updates simultaneously. The program doesn't offer much in terms of help; but, thankfully, it's pretty easy to navigate on its own.

The program's user interface is fairly intuitive. A menu bar resides at the top of the window, and large shortcut commands sit below it. A sidebar on the left side lets you view programs in the process of downloading, as well as any completed downloads. We quickly jumped into program and clicked the New button. A window appeared that let … Read more

With major questions still unresolved about sudden acceleration incidents in Toyotas and other vehicles, Washington is turning to NASA engineers and the broader scientific community to examine everything from mechanical defects and human error to electronic controls and electromagnetic interference.

On Tuesday, U.S. Transportation Secretary Ray LaHood announced the start of two major investigations designed to look deeper into potential causes of unintended vehicle acceleration, which have been tied to a number of accidents, including some fatal ones. The issue has blown up into a major problem for the auto industry and for Toyota especially, leading to a massive … Read more

Toyota on Monday released information that calls into question a driver's account of uncontrollable acceleration affecting his Toyota Prius in San Diego.

In a video released Monday by Toyota titled "Toyota preliminary findings of alleged runaway Prius," Toyota Motor Sales Vice President Mike Michels questioned Jim Sikes' account of uncontrolled acceleration in his Prius last week in San Diego.

On March 7, James Sikes called 911, saying the accelerator in his Prius was stuck and he couldn't slow down. The event was thought to be related to glitches that, in rare cases, may cause uncontrolled acceleration … Read more

A U.S. government agency and Toyota could not replicate an alleged runaway Prius incident in San Diego, according to an Associated Press report.

On March 7, James Sikes called 911, saying the accelerator in his Prius was stuck and he couldn't slow down. The event was thought to be related to mechanical or electronic glitches that, in rare cases, may cause uncontrolled acceleration in the Toyota Prius.

But in a memo drafted for a congressional panel, technicians with National Highway Traffic Safety Administration and Toyota were unable to replicate the problem on Sikes' car, according to the AP report.

"Every time the technician placed the gas pedal to the floor and the brake pedal to the floor, the engine shut off and the car immediately started to slow down," the report said. The memo went on to say that it would not be likely that Sikes's gas pedal would be stuck while he was slamming on the brakes at the same time.

A similar conclusion was reached by Edmunds.com on Friday, which CNET reported based on an interview with Dan Edmunds, director of vehicle testing at Edmunds. The car Web site conducted a test on a Prius in an attempt to replicate the problem that Sikes… Read more
