PlanetCommand&Conquer and Defense Tech report that the United States Navy is going to sink the U.S.S. America, decommissioned since 1996, to find out what happens when the 1060-foot long carrier gets hit, hard.
Dr. Batty, who works at the Dunstaffnage marine centre near Oban, and his colleagues were looking at whether herrings could detect sounds made by predators like whales and dolphins. Using infrared lighting with video cameras and underwater microphones, they monitored the herrings behaviour round the clock. "We heard these rasping noises, which sound like high pitched raspberries, only ever at night, whenever we saw tiny gas bubbles coming from the herrings' bottoms," said Dr Batty. "We also noticed that individual fish release more bubbles the more fish are in the tank with them. In other words, it seems that herring like to fart in company," commented Dr. Wilson.
This BBC NEWS article says Scientists may have found what makes a tune catchy, after locating the brain area where a song's "hook" gets caught. A US team from Dartmouth College, reported in the journal Nature, played volunteers tunes with snippets cut out. They scanned for brain activity and found it centred in the auditory cortex -- which handles information from ears. When familiar tunes played, the cortex activity continued during the blanks - and the volunteers indeed said they still mentally "heard" the tunes.
This BBC News UK story says experts invented a mannequin with a motorised mouth to test the amount of crumbs biscuits produce.
CNN.com reports that children, who drink more milk, do not necessarily develop healthier bones, researchers said on Monday in a report that stresses exercise and modest consumption of calcium-rich foods such as tofu. The U.S. government has gradually increased recommendations for daily calcium intake, largely from dairy products, to between 800 and 1,300 milligrams to promote healthy bones and prevent osteoporosis. But the report, published in the journal Pediatrics, said said boosting consumption of milk or other dairy products was not necessarily the best way to provide the minimal calcium intake of at least 400 milligrams per day.
This CNN.com article reports that the Dodge Neon, Ford Focus, and Volkswagen New Beetle are among the small cars that got the lowest safety rating in new side-impact crash tests performed by the insurance industry, according to results released Sunday. Fourteen of the 16 cars tested earned a "poor," the lowest of four ratings, the Insurance Institute for Highway Safety said...

This Live Science article says a recent college students' study of IM-ing found that the communication was more formal â€“- in use of vocabulary and abbreviations -â€“ than might be expected in a speech-like medium. The research also uncovered significant differences in how men and women use the medium.
Hamster project shows a symbiotic exchange of hoarded energy in aiming to establish a symbiosis between a population of hamsters and a group of vehicles with intelligent steering units. It is a documentation about the development of the project. There are photographs and a few streaming Real videos. The installation was part of the "Cyberarts 1999"-exhibition in the "OK- Museum of Contemporary Art" during the "Ars Electronica 1999/ Life Science"-Festival in Linz/Austria (September 4-18).
FOXNews.com report that the distinctive "male" smell was discovered in urine from male mice. It's produced by a chemical called MTMT (methylio) methanethiol. Female mice don't make MTMT. Neither do castrated male mice, which lack sex hormones. The compound converts easily into an odoriferous gas. Many compounds in the urine are used to signal reproduction and territorial recognition, say the researchers.

CNN.com reports that Samuel W. Alderson, the inventor of crash test dummies that are used to make cars, parachutes and other devices safer, has passed away at the age of 90 (2/11/2005). He grew up tinkering in his father's custom sheet-metal shop, worked on various military technology and by 1952 had formed Alderson Research Labs. The company made anthropomorphic dummies for use by the military and NASA in testing ejection seats and parachutes. The dummies were built to approximate the weight and density of humans and hold data-gathering instruments.
Yahoo! News report that archaeologists have begun underwater excavations of what is believed to be an ancient city and parts of a temple uncovered by the tsunami off the coast of a centuries-old pilgrimage town.
I saw this on KTLA 5's morning news yesterday, but I forgot to look for an online story to post on here.
CNN reports that hot cup of coffee may do more than just provide a tasty energy boost. It also may help prevent the most common type of liver cancer. A study of more than 90,000 Japanese found that people who drank coffee daily or nearly every day had half the liver cancer risk of those who never drank coffee.
Animal studies have suggested a protective association of coffee with liver cancer, so the research team led by Monami Inoue of the National Cancer Center in Tokyo analyzed a 10-year public health study to determine coffee use by people diagnosed with liver cancer and people who did not have cancer. They found the likely occurrence of liver cancer in people who never or almost never drank coffee was 547.2 cases per 100,000 people over 10 years. But for people who drank coffee daily the risk was 214.6 cases per 100,000, the researchers report in this week's issue of the Journal of the National Cancer Institute.
The New York Times (no registration needed) report that Dr. Demaine, an assistant professor of computer science at the Massachusetts Institute of Technology and the leading theoretician in the emerging field of origami mathematics, is holding is a hyperbolic parabaloid. It is a shape well known to mathematicians -- or something very close to that -- but he wants to be able to prove this conjecture, but difficullt to do.
TheShadow (remove AQFL to e-mail) sent me an interesting PBS' documentary on how Americans, as seen and heard, through the way we speak. It was premiered on January 5th, 2005, but its Web site was still informative like:
- Words that shouldn't be -- Spambot, cybercat, etc. Are we ruining the language?
- From sea to shining sea -- Exactly how many varities are there of American English?
- What speech do we like best? -- Language expreesses who we are, and who we want to be. It can also unite or divide us.
- What lies ahead? -- Is TV making us sound alike? Will cars sound like men or women? What's ahead for American English?
