From Science Daily:

ScienceDaily (Aug. 28, 2009) — University of Utah researchers used data from Portuguese water dogs – the breed of President Barack Obama's dog Bo – to help find a gene that gives some dogs curly hair and others long, wavy hair.

It was part of a National Institutes of Health (NIH) study – published online Thursday, Aug. 27 by the journal Science – showing that variations in only three genes account for the seven major types of coat seen in purebred dogs. The findings also point the way toward understanding complex human diseases caused by multiple genes.

From Time Magazine:

Like more than a billion fellow Muslims around the world, Sulley Muntari began the monthlong fasting ritual of Ramadan on Aug. 22. Abstaining from food or drink during daylight hours is challenging enough for the average person, but for the Ghana-born Muntari, a professional soccer player with Italy's Serie A team Inter Milan, running more than six miles per game on an empty stomach might have proved to be too much. In his first match after the start of Ramadan, the midfielder was removed from the game after just half an hour of play.

From Technology Review:

A breakthrough explores the challenges--and suggests the financial possibilities--of creating quantum networks.

In recent years, the Austrian physicist Anton Zeilinger has bounced entangled photons off orbiting satellites and made 60-atom fullerene molecules exist in quantum superposition--essentially, as a smear of all their possible positions and energy states across local space-time. Now he hopes to try the same stunt with bacteria hundreds of times larger. Meanwhile, Hans Mooij of the Delft University of Technology, with Seth Lloyd, who directs MIT's Center for Extreme Quantum Information Theory, has created quantum states (which occur when particles or systems of particles are superpositioned) on scales far above the quantum level by constructing a superconducting loop, visible to the human eye, that carries a supercurrent whose electrons run simultaneously clockwise and counterclockwise, thereby serving as a quantum computing circuit.

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.

From Science Daily:

Science Daily (Aug. 28, 2009) — Subtle connections between the 11-year solar cycle, the stratosphere, and the tropical Pacific Ocean work in sync to generate periodic weather patterns that affect much of the globe, according to research appearing this week in the journal Science. The study can help scientists get an edge on eventually predicting the intensity of certain climate phenomena, such as the Indian monsoon and tropical Pacific rainfall, years in advance.

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."

NASA’s Most Awesomely Weird Mission Patches


From Wired Science:

Perhaps the best thing about NASA’s military provenance is that the agency picked up the armed services’ habit of making patches.

We’ve long loved the Most Awesomely Bad Military Patches series that our sister blog, Danger Room, runs. Then, earlier this week, space collectors bid up the accidentally limited edition Stephen Colbert treadmill patch to more than $175 on eBay.

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.

My Comment: If this does not give you a cold chill down your spine .... nothing will.

In my case, I am dependent on the web for my information and communication. Any interruption will be catastrophic to me professionally as well as personally.

But I know that in the event of a national security emergency .... my concerns will be thrown out the window. I can easily the Government simply cutting off the web to the public and/or severely limiting its use. China already has some form of control over the web for its citizens, and I am sure that Iran wished it had a better handle on its access to the web. For the U.S. .... this control will become fact within a year.

Milk Was The World's First Superfood

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.
