Cutting Edge

Shares of Tesla Motors soared nearly 8 percent today after the company disclosed it had accelerated production of its electric vehicles in the third quarter.

In a letter to shareholders, CEO Elon Musk and Chief Financial Officer Deepak Ahufa said the company had reached a "fundamental turning point" making the transition to a mass production car company that was able to pass through a proverbial "valley of death."

"Overall, I feel Tesla was really kind of past the point of high risk. Several months ago, I said I thought that the coming several months would … Read more

It's as if you've just strolled up to Curiosity on the surface of Mars and surprised the rover as -- convinced that everyone at Mission Control is on a coffee break -- it's decided to ditch the scientific research for a bit and build a martian sand castle instead.

One of the latest Curiosity images posted by NASA is a stunning self-portrait made up of 55 high-rez images taken by the rover's Mars Hand Lens Imager. The base of Mount Sharp serves as a dramatic backdrop, swooping up toward the right, and in front of the rover, you can see four hand-size holes in the ground where Curiosity had just started building its sand castle gathered scoops of martian dirt for analysis. The scoop site is poetically named "Rocknest."… Read more

Hurricane Sandy has destroyed houses, cars, and boats, and caused some $20 billion in property damage, but one robot rode out the storm at sea without a scratch, as far as its maker can tell.

Liquid Robotics said one of its Wave Glider marine robots named Mercury was 100 miles east of Toms River, N.J., when Sandy hit, but the machine continued to function.

It withstood winds of up to 70 knots and continued to transmit real-time weather data about the storm. … Read more

KENNEDY SPACE CENTER, Fla. -- By dawn's early light today, the shuttle Atlantis was hauled out of the cavernous Vehicle Assembly Building for the last time, rolling not to the launch pad but to the spaceport Visitor Complex 10 miles away, where it will go on public display next year -- the last of the iconic winged orbiters to make the transition to Earth-bound museum duty.

Mounted atop a 76-wheel transporter, Atlantis was slowly rolled out of the VAB starting at 3:30 a.m. PT, cheered on by a crowd of several hundred spaceport workers; a throng of … Read more

This Sunday, amputee Zak Vawter will stand at the foot of Chicago's Willis Tower and focus his thoughts on climbing. If all goes according to plan, his bionic leg will listen to those thoughts and he'll ascend 103 flights without a hitch.

Vawter, who lost his right leg in a motorcycle accident in 2009, will be wearing a cutting-edge, thought-controlled prosthetic that's about to make a very public debut. He'll head up the 1,451-foot skyscraper (also known as Sears Tower) as part of SkyRise Chicago, an indoor stair-climbing fund-raising event for the Rehabilitation Institute of … Read more

In the aftermath of superstorm Sandy, researchers are discovering the damage the done to one of New York University's research facilities and mourning the loss of lab animals and of scientific data that could take years to rebuild.

After the New York Daily News reported on Tuesday that flooding and power loss claimed the lives of thousands of lab mice as well as wiping out enzymes, antibodies, and DNA used in cancer and other research, the NYU Langone Medical Center confirmed in a statement released yesterday that its Smilow building was "adversely impacted" by the speed and severity of the flood surge.… Read more

Dutch designer Daan Roosegaarde thinks we drive on dumb roads. So he teamed with mega European construction company Heijmans Infrastructure to create a vision of a "smart highway" for the Netherlands -- and possibly the rest of the world.

Perhaps the most exciting aspect of these future roads is the fact that two concepts of the bunch -- glow-in-the-dark roads and dynamic paint -- should arrive by mid-2013. The group plans to introduce the rest of the concepts before 2015, giving the world a glimpse at how technology could revolutionize the way we drive by making it a safer and more sustainable experience. … Read more

Smartphone batteries may soon last twice as long -- if an MIT spinoff's power amplifier technology lives up to its promise.

The power amplifier is one of the most power-hungry pieces of hardware in a phone. It converts electricity into radio signals and consumes power in two basic modes: standby and output signal for sending out digital data. Such a chip wastes more than 65 percent of its energy, according to a report in the MIT Technology Review, and the only way to make it more efficient is by reducing the power used in standby. … Read more

British scientists have come up with a super-sensitive prototype sensor that lets doctors detect early stage diseases with the naked eye, an innovation that could prove valuable in countries that lack the resources for expensive diagnostic equipment.

The sensor, created at Imperial College London, relies on nanotechnology to analyze serum derived from blood samples.

A positive reaction to p24, a protein that indicates early HIV infection, or PSA, a protein that at certain levels can indicate prostate cancer, generates irregular clumps of nanoparticles that emit a blue color in a solution kept in a disposable container.

A negative reaction, however, … Read more
