3800-year-old mummy gets a face

22 Jun 2006

Computer-generated image of mummy faceOn June 21, researchers at Waseda University's Institute of Egyptology unveiled the computer-generated facial image of an ancient Egyptian military commander that lived about 3,800 years ago. The image is based on CAT scans taken of a mummy.

Researchers claim the mummy, which was unearthed near Cairo at an archeological site in North Dashur, is from ancient Egypt's 13th dynasty (c.1756 to c.1630 BC), and according to inscriptions on the sarchophagus, it appears to be that of a military commander named Senw.

The facial image, which was created by a team of graphic artists from the Joshibi University of Art and Design, is based on bone structure data obtained from CAT scans of the mummy. The research group determined that he was a middle-aged to elderly man, and from information such as the military commander's title they hypothesized he was of mixed race. The artists worked to provide the face with strong, military commander-like features, referring to ancient Egyptian pictorial representations and sculptures.

"We had to rely on artististic imagination for the parts we did not understand," says Sakuji Yoshimura, Waseda University professor who led the research team. Several faces were generated, and the one that most resembled that of a military commander was chosen.

The face will be on display to the public beginning in July at Fukuoka City Museum.

Nasal airflow regulator amplifies whispers

21 Jun 2006

Nasal airflow regulatorOn June 20, an Okayama University team of researchers led by Professor Shogo Minagi unveiled a nasal airflow regulator designed to alleviate voice loss such as that which sometimes occurs after a stroke.

In normal speech, the soft palate (located at the back of the roof of the mouth) works to regulate the amount of air expelled through the mouth and nose. When these nerves are damaged by a stroke, for example, the soft palate may sag, preventing air from escaping through the nose. The result is the inability to pronounce speech sounds.

When inserted into the nostrils, the device forces air through the nasal passage when speaking, enabling sounds to be produced. According to the developers, the device allows people with nasal airflow problems -- even those whose speech is all but inaudible -- to be clearly heard.

Petaflops-level supercomputer to be unveiled

20 Jun 2006

MDGRAPE-3

On June 19, Japan's Institute of Physical and Chemical Research (Riken), SGI Japan and Intel announced the development of a supercomputer with a theoretical peak performance of 1 petaflops (one million billion floating point operations per second). Known as the MDGRAPE-3 (or the Protein Explorer), the computer system is designed to perform molecular dynamics simulations of such phenomena as non-bonding interactions between atoms.

The system consists of 201 units equipped with 24 of RIKEN?s MDGRAPE-3 LSI chips for molecular dynamics simulation (total of 4,808 chips), which are connected to 64 parallel servers equipped with 256 of Intel's Xeon 5000-series cores and 37 parallel servers equipped with 74 Xeon 3.2 GHz cores.

In the future, RIKEN plans to further upgrade the system with Xeon 5100-series processors (codenamed Woodcrest), and testing is now underway.

The LINPACK Benchmark, which is the standard for the Top 500 List, could not be performed on the system, so the performance cannot be compared directly with the world's other top supercomputers. However, the system's theoretical peak performance of 1 petaflops will set the computer firmly at the top of the list, with a speed about three times that of IBM's BlueGene/L at Lawrence Livermore National Laboratory (currently No.1 on the list).

The system will be unveiled to the public on June 24 at RIKEN's Yokohama laboratory.

Animatronic panda suit for rent

01 Jun 2006

Here's some welcome news for anyone not jiving with the whole 2006 "cool biz" fashion campaign that was officially launched today...

Multimedia production company Buildup Co., Ltd. has announced plans to begin renting high-quality animatronic suits in June. First up for rent will be the company?s panda suit.

The realistic-looking panda suit consists of two layers -- an inner layer of padding to reproduce the panda?s muscles and an outer layer featuring a coat of high-quality fur. The eyes, ears and mouth are equipped with a total of 14 remote control servo motors, allowing the panda to make facial expressions ranging from pleasant smiles to angry grimaces. To add to the realism, the designers eliminated the peepholes for the person inside. Instead, the performer sees by means of video goggles connected to a CCD camera system.

Although Buildup generally loans its suits to production companies, the panda suit is available for rent to individuals as well. With the rental service scheduled to begin today (June 1), the company has yet to announce the rental price. Only one panda suit is available at the moment, but Buildup is looking into expanding its lineup with suits modeled after other animals.

You can see a short video of the panda frolicking on the side of a road on Buildup's panda suit webpage.

“Living fossil” coelacanth captured on video

31 May 2006

=========================
*** Watch the VIDEO ***
=========================

On May 30, a Japanese research team videotaped a one-meter long coelacanth in its natural habitat in the waters off the coast of Indonesia's Sulawesi island. According to the announcement by Aquamarine Fukushima -- a marine science museum located in Fukushima prefecture -- this is the first video of a coelacanth in its Indonesian habitat since a German team videotaped one in 1999.

Coelacanth

Researchers at Aquamarine have been studying the coelacanth since the facility opened in 2000, and a research team has been stationed in Indonesia since last year. Researchers used a camera mounted on a remotely operated vehicle (ROV) to shoot a 10-minute video of the coelacanth. The video reportedly shows the fish lurking in a rocky cave located about 500 meters off the coast of Buol in northern Sulawesi, at a depth of about 170 meters. The museum has not indicated when the video will be shown to the public.

"The camera light caused the fish's eyes to glow green. It was there. Its body was dark blue," the research team reported to museum director Yoshitaka Abe on the telephone.

"Congratulations. Well done," Abe told the researchers. "This is a big first step in our research."

UPDATE (June 2, 2006): This translation was referenced by Loren Coleman on Cryptomundo, where you can find a lot of interesting background info about the coelacanth. He also discusses the potential significance of the reported "dark blue" color of the one caught on this video (Latimeria menadoensis, the Indonesian species, is supposed to be brown).

The German team that first filmed the coelacanth in Indonesia in 1999 was led by one Hans Fricke (See: http://www.dinofish.com/jago.html). I could not find his video of the Indonesian coelacanth online, but I came across these fantastic videos he shot of the African species (Latimeria chalumnae). In one of them, a coelacanth displays its trademark "handstand" posture.

Rainy season brings glow-in-the-dark mushrooms

24 May 2006

Glowing mushroomsWith the arrival of Japan's rainy season, a mysterious type of green, glow-in-the-dark mushroom begins to sprout in Wakayama prefecture. The Mycena lux-coeli mushrooms, known locally as shii no tomobishi-dake (literally, "chinquapin glow mushrooms"), sprout from fallen chinquapin trees. As they grow, a chemical reaction involving luciferin (a light-emitting pigment contained within the mushrooms) occurs, causing them to glow a ghostly green.

The luminescent mushrooms were long believed to be indigenous solely to Tokyo's Hachijojima Island after they were discovered there in the early 1950s. In 1995, however, mycologists found the fungus growing wild in coastal areas of the southern Kii peninsula, as well as in Kyushu and other areas.

The mushrooms thrive in humid environments, popping up during Japan's rainy season, which typically lasts from the end of May to July. The caps can grow to as large as 2 cm (about 1 inch) in diameter, but because the mushrooms are prone to dehydration, they only have a few days to live once the rain stops.

New images of disintegrating “lost comet”

12 May 2006

The National Astronomical Observatory of Japan?s (NAOJ) Subaru Telescope in Hawaii has captured new images of the Schwassmann-Wachmann 3 comet, which became known as a "lost comet" when it disappeared for 50 years after its discovery in 1930. On May 12 (today) the comet reaches the closest point to the Earth in its 5.4-year elliptical orbit around the sun.

The images show the disintegration of the comet's Fragment B. Short tails can be seen on some of the pieces, which are believed to have broken off recently.

Schwassmann-Wachmann 3, the lost cometAccording to NAOJ, the comet is disintegrating as it orbits the sun, and has broken into at least 50 pieces. The Subaru Telescope images show 13 small fragments near the bright Fragment B. The researchers plan to compare the images with observation data from other telescopes to get a better understanding of the comet's disintegration.

Fragment C, which is the brightest, is visible near the Lyra constellation in the eastern sky at around 12:00 midnight (in Japan), and Fragment B is visible near the Hercules constellation. On May 12, the comet will be 12 million kilometers (7.5 million miles) from the Earth, about 30 times the distance to the moon.
