Cutting Edge

Electronic paper is stacking up to be a high-growth market, according to a new report.

Sales of e-paper displays are projected to soar from $431 million this year to $9.6 billion in 2018, market researcher DisplaySearch said Wednesday.

The number of units sold is forecast to grow 22 million this year to 1.8 billion in 2018.

E-books are currently the main use and sales driver for e-paper. Most e-book readers, such as the Amazon Kindle and Sony Reader, use the electrophoretic display technology from E Ink. A few e-readers, such as Fujitsu's Flepia, use a different technology … Read more

The U.S. Navy may have developed a solution to hull-dwelling barnacles and slime--a "foul" problem that has plagued sailors and their ships since Noah launched the ark.

The Office of Naval Research (ONR) has developed what looks like a combination pressure washer/minisub called the Hull Bio-inspired Underwater Grooming, or Hull BUG. It's designed to prevent or suppress the growth and build-up of nuisance marine growths such as barnacles--also known as biofouling (PDF).

This could be a major breakthrough. High-performance warships and submarines rely on a clean hull for speedy acceleration and hydroacoustic stealth--things that crustaceans … Read more

KENNEDY SPACE CENTER, Fla.--The shuttle Discovery's planned launch early Wednesday on a space station resupply mission was called off during fueling Tuesday when a valve in a liquid hydrogen feedline apparently failed to close properly. Launch was tentatively reset for Friday, assuming the problem can be resolved in time.

Engineers plan to test the suspect hydrogen fill-and-drain valve Wednesday to determine if the valve or a sensor system that measures its position is to blame for the readings that forced NASA to order Discovery's second delay in a row. Bad weather blocked a launch attempt early Tuesday.… Read more

The Stanley Steamer may have finally been dethroned.

After holding onto its land speed record for 103 years, the homegrown Stanley automobile from the early days of motoring has been overtaken by a late-model import. The British Steam Car team said Tuesday that, earlier in the day, in the two runs required to be considered for the record, the Steam Car averaged 139.843 mph over a measured mile.

Tuesday's achievement still awaits official confirmation from the certifying agency, the Federation Internationale de l'Automobile.

The steam-powered mark to beat was 127 mph, set in 1906 by Fred Marriott, … Read more

KENNEDY SPACE CENTER, Fla.--Florida's hard-to-predict weather threw the shuttle Discovery's crew a curve ball early Tuesday, worsening when forecasters predicted improvement, generating unexpected lightning and offshore storms.

While conditions improved as the morning wore on, the launch team ran out of time and NASA managers were forced to order a 24-hour delay.

"Well, looks like everything else was cooperating except for our local area weather," Launch Director Pete Nickolenko said to Mike Moses, chairman of NASA's Mission Management Team, during a final hold in the countdown.

"Yep, if we had 30 more minutes … Read more

On the heels of a scientific report last month saying 63 percent of world fish stocks require rebuilding, scientists at MIT have unveiled a new robot fish that's cheap to make and ripe for mass production.

Actually, MIT engineers Kamal Youcef-Toumi and Pablo Valdivia Y Alvarado aren't aiming to replenish fisheries. They want their robot swimmers to be used for underwater monitoring of pipelines, sunken ships, and pollution. Since the fish are less than a foot long, they can maneuver into spaces that are too tight for most underwater autonomous vehicles (UAVs).

The fish--while not as pretty as these toxin-sniffing robot carp patrolling Spanish waters--are notable for their novel design. They have fewer than 10 parts, making them low-cost, and are housed in a continuous flexible polymer casing that prevents water damage.

Lacking different segments, the fish can swim more naturally, according to MIT (watch the video after the jump). A single motor in the middle initiates a wave that moves along the body and propels it forward. Real fish move in a similar fashion by contracting muscles on either side of their bodies.

Youcef-Toumi noted that the polymers allow for stiffness to be specified in different sections, adding that another application would be robotic prosthetic limbs.

The early versions of the fish, about 5 inches long, swam like bass and trout, with movement concentrated in the tail.… Read more

While unmanned air vehicles are putting pilots out of business, a new U.S. Army-funded robot could do the same for rescuers and stevedores.

The humanoid BEAR (Battlefield Extraction-Assist Robot) can locate victims in a mine shaft, battlefield, toxic spill, or earthquake-damaged structure. And then it can lift them up and then carry them over long distances to safety, according to the manufacturer Vecna Robotics. And it does this without risking any more lives (PDF).

The challenge was to enhance search and rescue while reducing the time military, police, and emergency response personnel have to risk their lives each day. … Read more

DARPA is spending millions of dollars to identify trash cans, which may have raised a few eyebrows, except these and other common urban objects could in the course of today's combat missions prove to be tactically significant.

BAE Systems received a $7.1 million contract to work on Phase II of the Urban Reasoning and Geospatial Exploitation Technology (URGENT) program, which is designed to improve the quality and timeliness of geospatial intelligence U.S. troops receive when facing enemy threats in urban environments.

This phase of the program's goal will be to "develop a 3D reasoning engine … Read more
