Dying Languages Archived For Future Generations

Cambridge University

From The Telegraph:

A Cambridge University project to safeguard the world's 6,000 spoken languages has been launched after it emerged half could die out within a generation.

The World Oral Literature Project aims to help cultures under threat from globalisation create lasting records of their native languages.

Still in its inaugural year, the project led by Cambridge University's Museum of Archaeology and Anthropology, has already handed out around 10 grants to tribes from Mongolia to Nigeria - and the researchers admitted traditional British languages such as Cornish and Gaelic are also at risk.

From Breitbart/AFP:

A satellite launched by South Korea's first space rocket is thought to have burnt up in the Earth's atmosphere after missing its designated orbit, officials said Wednesday.

Seoul vowed to press on with its drive to become a space technology leader despite Tuesday's setback, caused by the defective operation of a fairing covering the satellite.

The science and technology ministry said one of the two aerodynamic fairings covering the rocket's tip failed to fall away, after opening in preparation for the satellite's release.

From Science Now:

Look at an image of the Milky Way galaxy, and you can't help but notice its exquisite spiral arms. For nearly 100 years, astronomers have tried to understand how the Milky Way and other spiral galaxies formed these dramatic patterns--and now they think they finally have the answer.

Current thinking about how spiral galaxies form traces back to an idea nearly 2 millennia old, to 2nd-century Egyptian mathematician Ptolemy. Trying to describe how the five planets in the night sky followed seemingly irregular paths, Ptolemy hit upon an idea he called epicycles.

From Science Daily:

ScienceDaily (Aug. 25, 2009) — Solar cells could soon be produced more cheaply using nanoparticle “inks” that allow them to be printed like newspaper or painted onto the sides of buildings or rooftops to absorb electricity-producing sunlight.

Brian Korgel, a University of Texas at Austin chemical engineer, is hoping to cut costs to one-tenth of their current price by replacing the standard manufacturing process for solar cells – gas-phase deposition in a vacuum chamber, which requires high temperatures and is relatively expensive.

Fill Her Up! The World's Highest Garage Attendant Prepares Space Shuttle Discovery For Launch

Perched 153ft above the ground a Nasa technician prepares the liquid oxygen tank on the US space shuttle Discovery. Today's launch was scrubbed after a faulty fuel valve was detected

From The Daily Mail:

Next time you find yourself tapping your foot impatiently as you fill up your car with petrol spare a thought for Nasa engineers.

They have the task of filling the space shuttle Discovery's external fuel tank with nearly two million litres of liquid hydrogen and oxygen. The process takes the best part of a day and leaves Nasa with a hefty energy bill.

The liquid oxygen is stored in the top of the nose cone while the liquid hydrogen makes up the bottom half of the tank. They are fed through to the three main engines at an impressive speed, with oxygen pumping through at 80,000 litres a minute and hydrogen at 215,000litres a minute.

Climate Tipping Point Defined For US Crop Yields

From The New Scientist:

While news reports and disaster movies remind us about tipping points for Arctic melt and sea level rise, some things closer to home get less attention. Take food supply: new modelling studies show that there are climate tipping points here too, beyond which crop yields will collapse.

Wolfram Schlenker at Columbia University, New York, and Michael Roberts at North Carolina State University in Raleigh used a high-resolution dataset of weather patterns from 1950 to 2005 to discover how yields of three key US crops would respond to increasing temperatures.

Jessica Biel Most 'Dangerous' Celeb In Cyberspace

From CNET:

Through no fault of her own, actress Jessica Biel is now the most hazardous celebrity on the Internet.

Fans searching online for Biel have a one-in-five chance of hitting a Web site with malware, according to McAfee's third annual report listing Hollywood's most "dangerous" online celebrities.

In general, hunting for Hollywood's in-crowd poses a much greater threat than searching for just about anyone else. For example, President Obama and first lady Michelle Obama ranked No. 34 and No. 39, respectively.

Why Craigslist Is Such A Mess

From Wired News:

The Internet's great promise is to make the world's information universally accessible and useful. So how come when you arrive at the most popular dating site in the US you find a stream of anonymous come-ons intermixed with insults, ads for prostitutes, naked pictures, and obvious scams? In a design straight from the earliest days of the Web, miscellaneous posts compete for attention on page after page of blue links, undifferentiated by tags or ratings or even usernames. Millions of people apparently believe that love awaits here, but it is well hidden. Is this really the best we can do?

3 New Farm Bots Programmed To Pick, Plant And Drive

From Popular Mechanics:

Intelligent, manned machines aren’t just for warplanes and border guards—they can be found on the farm too. Increasingly, agro-bots are taking laborious tasks out of the farmer’s helper’s hands, and saving time and money in the process. Here are three robotic farm servants who may right now be working in a field near you.

Agricultural robots are already among us: mowing grass, spraying pesticides and monitoring crops. For example, instead of regularly dousing an entire apple orchard with chemicals, towed sensors find diseases or parasites with infrared sensors and cameras, and spray only the affected trees. But could a robot wholly replace a migrant worker?
