Hairy Hearing

Inner ear hair cells. Colored scanning electron micrograph (SEM) of sensory hair cells from the organ of corti, in the cochlea of the inner ear. These cells are surrounded by a fluid called the endolymph. As sound enters the ear it causes waves to form in the endolymph, which in turn cause these hairs to move. The movement is converted into an electrical signal, which is passed to the brain. The V-shaped arrangement of hairs lies on the top of a single cell. Magnification: x21,000 when printed 10cm wide.

Brain Array

​

Here, microwires emerging from the green and orange tubes connect to two arrays of 16 microelectrodes. Each array is embedded in a small mat of clear, rubbery silicone. The mats are barely visible in this image. These microelectrode arrays sit on the brain without penetrating it, a step toward longer-lived, less invasive versions of "neural interfaces" that in recent experiments elsewhere have allowed paralyzed people to control a computer cursor with their thoughts. The new microelectrode arrays were placed in two patients at the University of Utah who already were undergoing brain surgery for severe epilepsy. The larger, numbered, metallic electrodes are used to locate the source of epileptic seizures in the brain, so the patients allowed the microelectrodes to be placed on their brains at the same time.

Rescue Bot

Robo-Q, rescue robot of the Tokyo Fire Department, collects a mock injured man during an anti-terrorism exercise conducted by the Tokyo Metropolitan Government at Tokyo Big Sight on November 7, 2008 in Tokyo, Japan. The rescue robot is designed to collect humans from environments dangerous to firefighters. The first anti-RDD (radiological dispersal device) terrorism field training exercise on the local government level in Japan is being held to improve management abilities on RDD or 'dirty bomb' attack cases by using the latest equipment, facilities and vehicles

CCTV Tower in Beijing

CCTV's new headquarters in Beijing, wears its engineering on its sleeve. So complex is this 768-foot-tall anti-skyscraper that the architects, the Netherlands-based Office of Metropolitan Architecture, chose to show off the structural seams for visual effect.
The building is a continuous loop (resembling a twisted doughnut to some, "big shorts" to others), a shape that would normally be too stiff to stand up against the region's famously epic earthquakes. Inventive engineering provides the solution

Ares Rocket Engine Test

On Sept. 10, 2009, NASA lit up the Utah sky with the initial full-scale, full-duration test firing of the first stage motor for the Ares I rocket. The 154-foot solid rocket motor produced heat two-thirds the temperature of the sun and its 12-foot-diameter cylinder delivered 3.6 million pounds of thrust.

Robo-Thespians

Humanoid robots produced by Japan's Mitsubishi Heavy Industry, named Momoko (R) and Takeo (L) take part in a drama for the world's first robot and human experimental theatre, written and directed by Japanese playwright Oriza Hirata at Japan's Osaka University in Osaka, western Japan on November 25, 2008. The 20-minute performance was put on display for the media ahead of a possible run for the public next year.

Robotic Jellyfish​

Swimming around in their tank, these autonomous robotic jellyfish move alone or in a swarm and communicate with their brethren to avoid underwater collisions. Developed by German industrial-automation company Festo as an attention-grabbing experiment in cooperative robotics, each AquaJelly uses eight bendable “tentacles” to propel itself forward. But the AquaJelly does more than swim around and look pretty. Each is coated with conductive metal paint that draws the robot to a nearby charging station. It also has LED illumination, integrated pressure, light and radio sensors, and 11 infrared light-emitting diodes used for jelly-to-jelly communication.
Above water, the robots use a short-range radio system to signal to one another that a charging station is occupied. Markus Fischer, the head of corporate design at Festo, hopes the AquaJelly will lead to a robotic workforce that can adapt to complicated tasks. Whereas today’s robot assembly lines can produce only a single product, “there is a possibility that [someday] several autonomous robots will work together and produce personalized products.”

ATHLETE Space Rovers Practicing in California​

Two All-Terrain Hex-Legged Extra-Terrestrial Explorer (ATHLETE) rovers traverse the desert terrain adjacent to Dumont Dunes, CA. The ATHLETE rovers are being built to be capable of rolling over Apollo-like undulating terrain and "walking" over extremely rough or steep terrain for future lunar missions

Gaseous State​

Scientists measure methane at the source: In a lush pasture near Buenos Aires, this cow and its compatriots are digesting important information: how much methane—a greenhouse gas 20 times as potent as carbon dioxide—is released by the country’s 55 million bovines. Researchers from Argentina’s National Institute of Agricultural Technology connected inflatable tanks to the cows’ first stomach, where methane is made, through a small hole between their ribs.
By measuring methane production directly inside each cow, biologist Silvia Valtorta hopes to more accurately determine the country’s overall agricultural contribution to global warming. According to the data, an average cow releases more than 70 gallons of the stuff every day. But a change in diet could reduce that. Cows that eat mostly grain produce 20 to 25 percent less methane than grazing cows, and adding tannin—a bitter chemical found in wine—to the feed could lower it further.

The LHC's First Collision​

After 14 years of work and $5.5 billion, the LHC has survived faulty magnets, avian sabotage, and the threat of malevolent time travelers to finally collide its first particles.
This image shows the collision as recorded by the Compact Muon Solenoid (CMS) detector. The red and blue bars represent subatomic particles flying forth from the proton collision like atomic shrapnel. When the LHC finally ramps up to full power, the 3,600 scientists at the will witness the most powerful particle collisions ever engineered by man

Transiting the Sun​

In this tightly cropped image, the NASA space shuttle Atlantis is seen in silhouette during solar transit, Tuesday, May 12, 2009, from Florida. This image was made before Atlantis and the crew of STS-125 had grappled the Hubble Space Telescope. The photographer made this image using a solar-filtered Takahashi 5-inch refracting telescope and a Canon 5D Mark II digital camera

NASA's Super-Pressure High-Altitude Balloon​

This image, taken through a telescope, is of the newly designed super pressure balloon prototype at float altitude--during its groundbreaking flight test--over Antarctica. "This seven-million-cubic-foot super-pressure balloon is the largest single-cell, super-pressure, fully-sealed balloon ever flown. When development ends, NASA will have a 22 million-cubic-foot balloon that can carry a one-ton instrument to an altitude of more than 110,000 feet, which is three to four times higher than passenger planes fly."

Mars Parachute
​

A parachute destined for Mars experiences 81,250 pounds of drag force in the world’s largest wind tunnel at NASA Ames Research Center. Scientists went on to deploy the parachute 13 more times this past spring before deeming the 51-foot-diameter mammoth fit to land the next Red Planet rover, the Mars Science Laboratory. Cushioning a 2,000-pound rover from a supersonic descent in the thin Martian atmosphere demands special stamina. The chute gets its strength from stronger synthetic fiber, called Technora, in its suspension lines. Now a parachute identical to the one that was tested is packed and ready for the 2011 launch of the MSL mission, which will explore Mars for signs that it could have once supported life. “The parachute’s got a tough job,” says Douglas S. Adams, the MSL parachute senior engineer. “It passed [the tests] with flying colors.”

Watershed Moment​

Energy and environmentalism flow together to save the Grand Canyon: This frothy flume is what 300,000 gallons of water per second looks like. A 60-hour surge of almost 75 billion gallons, it’s part of an effort to revitalize the ecosystem of the Colorado River and the Grand Canyon. Teams from the U.S. Geological Survey, the Grand Canyon Trust and 25 other agencies have been working together since 1995 to develop a plan that will mimic natural flooding to redistribute sediment that would normally wash downriver. Moving the sediment from the central riverbed to the riverside rebuilds the sandbars downstream that serve as natural habitats and backwater nursery grounds for endangered fish species such as the humpback chub, as well as camping grounds for recreational use.
This most recent discharge was the third of its kind. The first, in 1996, washed what little sediment there was downstream past the Grand Canyon and into Lake Mead. The second, in 2004, redistributed too little sand. Definitive results on the success of this last experiment should be available within the year and will serve as a guidepost for the next flow, which is as yet unscheduled.

Kurtsystems Horse-Training Car​

A horse trots along a dirt road in Turkey, encased by the Kurtsystems Car equine training system. What may look like a complex horse-drawn carriage is actually a high-tech way to automate the delicate process of training racehorses. The horse isn’t pulling the four-and-a-half-ton, $427,000 vehicle. Rather, the vehicle keeps pace with the animal, and trainers fit the horse with equipment such as an electrocardiogram machine, oxygen masks and movement sensors to monitor its performance. They can then subtly regulate the horse’s speed for optimal training. Mehmet Kurt, the company’s founder, developed the device after his own horse died as a result of overtraining and human error. Kurt wanted a machine that would train horses to their full potential and eliminate such afflictions as lactic acidosis, by alerting trainers to muscular, circulatory and respiratory problems early.

Hearts Built to Order​

A dead heart beats again, thanks to the efforts of scientists at the University of Minnesota. To rebuild and reanimate the organ, which was harvested from a rat, scientists first stripped the old heart cells away with a detergent typically found in shampoos. That left behind a collagen matrix—the protein fibers that hold groups of cells together and help give organs their overall shape—which they then reseeded with heart cells from a newborn rat. They attached the organ to electrodes and waited. Then it happened: The heart started to beat regularly. “We were all running around like crazy, scared that it would [just stop and] never beat again,” says team member Harald Ott, a surgical resident at Massachusetts General Hospital in Boston. The reanimation technique is now being tested on pig hearts, which are much closer in structure to human hearts than are rat hearts. Organs from built-to-order collagen matrices could help treat the five million Americans who suffer from heart failure and the some 2,600 patients currently waiting for transplant donors.

Mechanical Heart​

McConkey imagines the heart as an elaborate machine, connected to the pipes and valves of brass musical instruments. The valves in this image were created from photographs of brass intruments and collaged together digitally, while the heart was converted from a pencil drawing using a computer and placed into the image.
