Crash of '29
Friday, February 27, 2009
The entry-level powerplant will be Volkswagen’s 3.6-liter six-cylinder engine with 300 horsepower. The ‘S’ model will deliver 400 hp from a 4.8-liter V8, and the Turbo variant will offer an estimated 500 horses. The Panamera S will start at $89,000, while the all-wheel-drive 4S will cost $93,800. The Turbo will ring in at $132,600, which is slightly more than a Cayenne Turbo. U.S. sales are to begin in October.

UNSOLD CARS AROUND THE WORLD
Nissan has announced plans to cut its Sunderland workforce by 1,200. Thousands of unsold cars are stored around the factory's test track
Honda is halting production at its Swindon plant in April and May, extending the two-month closure announced before Christmas to four months. Honda and Japanese rival Toyota are both cutting production in Japan and elsewhere. Pictured, Hondas await export at a pier in Tokyo
Earlier this week Jaguar Land Rover said 450 British jobs would go
The open car storage areas in Corby , Northamptonshire, are reaching full capacity
Imported cars stored at Sheerness open storage area awaiting delivery to dealers
Newly imported cars fill the 150-acre site at the Toyota distribution centre in Long Beach , California

New cars jam the dockside in the port of Valencia in Spain
Peugeot cars await shipment to Italian dealers at the port of Civitavecchia

With many manufacturers on extended Christmas shutdown, the number of cars rolling off production lines in December fell 47.5% to just 53,823
Thousands of new cars are stored on the runway at the disused Upper Heyford airbase near Bicester, Oxfordshire, on December 18, 2008.
Sales of new cars in the UK have slumped to a 12-year-low and production of cars at Honda in Swindon has been halted for a unprecedented four-month period because of the collapse in global sales and represents the longest continuous halt in production at any UK car plant. The announcement comes on a day when the EU's Industry Commissioner Guenter Verheugen warned the outlook for the European car industry was 'brutal' and predicted not all European manufacturers would survive the crisis.

Orbiting Space Junk a Growing Danger
Space flight is a risky business, but the chance of a deadly collision is increasing due to a spreading canopy of junk that's orbiting our planet. And the wreckage from a recent satellite collision is adding to the trash, making more collisions among spacecraft all but inevitable. WSJ's Robert Lee Hotz reports.

Researchers solve mystery of deep-sea fish with tubular eyes and transparent head
The barreleye (Macropinna microstoma) has extremely light-sensitive eyes that can rotate within a transparent, fluid-filled shield on its head. The fish's tubular eyes are capped by bright green lenses. The eyes point upward (as shown here) when the fish is looking for food overhead. They point forward when the fish is feeding. The two spots above the fish's mouth are olfactory organs called nares, which are analogous to human nostrils. Image: © 2004 MBARI
Researchers at the Monterey Bay Aquarium Research Institute recently solved the half-century-old mystery of a fish with tubular eyes and a transparent head. Ever since the "barreleye" fish Macropinna microstoma was first described in 1939, marine biologists have known that its tubular eyes are very good at collecting light. However, the eyes were believed to be fixed in place and seemed to provide only a "tunnel-vision" view of whatever was directly above the fish's head. A new paper by Bruce Robison and Kim Reisenbichler shows that these unusual eyes can rotate within a transparent shield that covers the fish's head. This allows the barreleye to peer up at potential prey or focus forward to see what it is eating.
Deep-sea fish have adapted to their pitch-black environment in a variety of amazing ways. Several species of deep-water fishes in the family Opisthoproctidae are called "barreleyes" because their eyes are tubular in shape. Barreleyes typically live near the depth where sunlight from the surface fades to complete blackness. They use their ultra-sensitive tubular eyes to search for the faint silhouettes of prey overhead.
Although such tubular eyes are very good at collecting light, they have a very narrow field of view. Furthermore, until now, most marine biologists believed that barreleye's eyes were fixed in their heads, which would allow them to only look upward. This would make it impossible for the fishes to see what was directly in front of them, and very difficult for them to capture prey with their small, pointed mouths.
In this image, you can see that, although the barreleye is facing downward, its eyes are still looking straight up. This close-up "frame grab" from video shows a barreleye that is about 140 mm (six inches) long.
Robison and Reisenbichler used video from MBARI's remotely operated vehicles (ROVs) to study barreleyes in the deep waters just offshore of Central California. At depths of 600 to 800 meters (2,000 to 2,600 feet) below the surface, the ROV cameras typically showed these fish hanging motionless in the water, their eyes glowing a vivid green in the ROV's bright lights. The ROV video also revealed a previously undescribed feature of these fish--its eyes are surrounded by a transparent, fluid-filled shield that covers the top of the fish's head.
Most existing descriptions and illustrations of this fish do not show its fluid-filled shield, probably because this fragile structure was destroyed when the fish were brought up from the deep in nets. However, Robison and Reisenbichler were extremely fortunate--they were able to bring a net-caught barreleye to the surface alive, where it survived for several hours in a ship-board aquarium. Within this controlled environment, the researchers were able to confirm what they had seen in the ROV video--the fish rotated its tubular eyes as it turned its body from a horizontal to a vertical position.
This face-on view of a barreleye shows its transparent shield lit up by the lights of MBARI's remotely operated vehicle Tiburon. As in the other photos, the two spots above the fish's mouth are are olfactory organs called nares, which are analogous to human nostrils.
In addition to their amazing "headgear," barreleyes have a variety of other interesting adaptations to deep-sea life. Their large, flat fins allow them to remain nearly motionless in the water, and to maneuver very precisely (much like MBARI's ROVs). Their small mouths suggest that they can be very precise and selective in capturing small prey. On the other hand, their digestive systems are very large, which suggests that they can eat a variety of small drifting animals as well as jellies. In fact, the stomachs of the two net-caught fish contained fragments of jellies.
After documenting and studying the barreleye's unique adaptations, Robison and Reisenbichler developed a working hypothesis about how this animal makes a living. Most of the time, the fish hangs motionless in the water, with its body in a horizontal position and its eyes looking upward. The green pigments in its eyes may filter out sunlight coming directly from the sea surface, helping the barreleye spot the bioluminescent glow of jellies or other animals directly overhead. When it spots prey (such as a drifting jelly), the fish rotates its eyes forward and swims upward, in feeding mode.
Barreleyes share their deep-sea environment with many different types of jellies. Some of the most common are siphonophores (colonial jellies) in the genus Apolemia. These siphonophores grow to over 10 meters (33 feet) long. Like living drift nets, they trail thousands of stinging tentacles, which capture copepods and other small animals. The researchers speculate that barreleyes may maneuver carefully among the siphonophore's tentacles, picking off the captured organisms. The fish's eyes would rotate to help the fish keep its "eyes on the prize," while its transparent shield would protect the fish's eyes from the siphonophore's stinging cells.

MBARI researchers speculate that Macropinna microstoma may eat animals that have been captured in the tentacles of jellies, such as this siphonophore in the genus Apolemia. The "head" of the siphonophore (at right) pulls the animal through the water, its stinging tentacles streaming out like a living drift net.
Robison and Reisenbichler hope to do further research to find out if their discoveries about Macropinna microstoma also apply to other deep-sea fish with tubular eyes. The bizarre physiological adaptations of the barreleyes have puzzled oceanographers for generations. It is only with the advent of modern underwater robots that scientists have been able to observe such animals in their native environment, and thus to fully understand how these physical adaptations help them survive.
