Crazy English: How China's Language Teachers Became Big Celebrities -- The Independent

This year it will be announced that China now has more English speakers than any other country in the world. And such is the demand for their services that top teachers have become big stars.

"Where are you from? Do you speak English?" It's a familiar phrase near the Forbidden City in Beijing, or along the capital's Nanjing Road, as Chinese people try a standard opening gambit to spark up a conversation with a foreigner. Many visitors baulk at being approached so baldly, and are worried that it could be a scam. Very occasionally it is a con – and tourists should be wary when some nice young people offer to bring them to a tea house – but mostly the youngsters are desperate for access to real live Anglophones who can help them improve their conversational English.

New Theory For Why We Cry

Do we cry because it makes us feel good, or because it cleanses us of stressful chemicals? Or, as Oren Hasson now theorizes, is a good cry just a way to get attention and gain acceptance? Image credit: stockxpert

From Live Science:

We shed tears when in pain, but what purpose does crying have?

A scientist now proposes a new theory for why crying evolved — tears can act as handicaps to show you have lowered your defenses.

"Crying is a highly evolved behavior," said researcher Oren Hasson, an evolutionary biologist at Tel Aviv University in Israel. "My analysis suggests that by blurring vision, tears lower defenses and reliably function as signals of submission, a cry for help, and even in a mutual display of attachment and as a group display of cohesion."

Watermelon Juice - Next Source of Renewable Energy

From Reuters:

Hundreds of thousands of tons of watermelons are tossed every year because they aren't good enough for market. A new study finds that the juice from these watermelons could easily be used to create the biofuel ethanol and other helpful products.

According to a new study to be published in the journal Biotechnology for Biofuels, 20% of the watermelon crop doesn't go to market every year due to imperfections, bad spots, or weird shapes. These watermelons are left in the field and then ploughed right back into the ground. According to the authors of the study (Benny Bruton and Vincent Russo from the USDA-ARS, South Central Agricultural Research Laboratory, and Wayne Fish), these watermelons could be used to produce the biofuel ethanol.

Funding "Exciting" Space Research

From The Atlantic:

It's not easy being a NASA researcher. You can spend years of your professional career working on a particular project, only to have it abruptly cancelled because a new Administration takes office or ... well, the country just shifts its sights and priorities. And your particular project no longer fits on the list. It's happened so many times over the agency's 50-year history that it's almost predictable. And the reasons for those shifts are numerous, and sometimes complex.

U.S. Senate Bill Will Give Control Of The Internet To The White House In The Event Of A National Security Emergency

Bill Would Give President Emergency Control Of Internet -- CNET

Internet companies and civil liberties groups were alarmed this spring when a U.S. Senate bill proposed handing the White House the power to disconnect private-sector computers from the Internet.

They're not much happier about a revised version that aides to Sen. Jay Rockefeller, a West Virginia Democrat, have spent months drafting behind closed doors. CNET News has obtained a copy of the 55-page draft of S.773 (excerpt), which still appears to permit the president to seize temporary control of private-sector networks during a so-called cybersecurity emergency.

From The Telegraph

Milk was the world’s first “superfood”, claim scientists, who believe that it helped prehistoric families inhabit harsh northern climes.

British researchers believe that humans first evolved into milk drinkers 7,500 years ago in the Balkans and used the ability to populate northern Europe, including Britain.

At the time, the north was very inhospitable, being cold and damp and covered in forests. Settlers would die if a crop failed.

Physicists Successfully Predict Stock Exchange Plunge

Predicting the drop (Image: Sipa Press/Rex Features)

From New Scientist:

WITH 20/20 hindsight, financial crashes seem inevitable, yet we never see them coming. Now a team of physicists and financiers have bucked the trend by successfully predicting a steep fall in the Shanghai Stock Exchange.

Their model, which employs concepts from the physics of complex atomic systems, was developed by Didier Sornette of the Financial Crisis Observatory in Zurich, Switzerland, and Wei-Xing Zhou of the East China University of Science and Technology in Shanghai. The idea is that if a plot of the logarithm of the market's value over time deviates upwards from a straight line, it's a clear warning that people are investing simply because the market is rising rather than paying heed to the intrinsic worth of companies. By projecting the trend, the team can predict when growth will become unsustainable and the market will crash.

From Technology Review:

The first full-scale test of the booster for NASA's Ares I rocket was called off because of a power failure.

Today NASA was supposed to conduct the first full-scale test of the motor for the first stage of its future space rocket, Ares I. The test, at NASA partner Alliant Techsystems, was in Utah at 3:00 P.M. EST and was intended to last two minutes. The goal was to obtain data on thrust, roll control, acoustics, and vibrations to aid engineers in designing Ares I. But the test was scrubbed 20 seconds before ignition of the 154-foot motor, which was anchored to the ground horizontally. The problem: failure of a power unit that drives hydraulic tilt controls for the rocket's nozzle, according to a local report. The static firing test of the motor has not yet been rescheduled.

From Science Daily:

ScienceDaily (Aug. 27, 2009) — Shell beads newly unearthed from four sites in Morocco confirm early humans were consistently wearing and potentially trading symbolic jewelry as early as 80,000 years ago. These beads add significantly to similar finds dating back as far as 110,000 in Algeria, Morocco, Israel and South Africa, confirming these as the oldest form of personal ornaments. This crucial step towards modern culture is reported this week in the Proceedings of the National Academy of Sciences (PNAS).

A team of researchers recovered 25 marine shell beads dating back to around 70,000 to 85,000 years ago from sites in Morocco, as part of the European Science Foundation EUROCORES programme 'Origin of Man, Language and Languages'. The shells have man-made holes through the centre and some show signs of pigment and prolonged wear, suggesting they were worn as jewelry.

A similar observatory in Washington State is also on the case. LIGO Scientific Collaboration

From Scientific American:

The ripples in spacetime predicted by general relativity remain one of the most sought-after prizes in physics, and new research narrows estimates of their prevalence.

Gravity waves spread through space and time like ripples on a pond, warping the fabric of the universe as they pass. The largest waves emanate from the most cataclysmic events in the universe: stellar explosions, mergers of black holes, and the violent first moments of cosmological history. Or so the venerable theory of general relativity goes—although many predictions of Albert Einstein's theory of gravity have been proved, only indirect evidence for gravity waves has been found.

Behind the Scenes With the World's Most Ambitious Rocket Makers

SpaceX propulsion chief Tom Mueller examines a spacecraft control thruster.

From Popular Mechanics:

An improbable partnership between an Internet mogul and an engineer could revolutionize the way NASA conducts missions—and, if these iconoclasts are successful, send paying customers into space

In late 2001, Tom Mueller was sacrificing his nights and weekends to build a liquid-fuel rocket engine in his garage.

Mueller, a propulsion engineer at Redondo Beach, Calif.–based aerospace firm TRW, felt like an “unwanted necessity” at his day job. His prolific ideas about engine design were lost at such a large, diverse company. To satisfy his creative impulses, he built his own engines, attached them to airframes and launched them in the Mojave Desert with fellow enthusiasts in the Reaction Research Society, America’s oldest amateur rocketry club. RRS members, many of them employees at aerospace firms, meet regularly in the Los Angeles area to build and launch the biggest and highest flying rockets they can—just as the group has done since it was founded in the early 1940s.
