From The Christian Science Monitor:

From Minnesota to Texas, wind power sweeps new jobs into old-tech towns.

Cedar Rapids and Estherville, Iowa

Hundreds of workers lost their jobs after the Rockwell-Goss printing press factory closed here in Cedar Rapids in 2001. The hulking empty shell sat idle on the outskirts of the city for four years.

But that was before wind power blew into town, bringing thousands of clean-tech manufacturing jobs to Iowa and the Midwest.

In many cases, the new industry is setting up shop in defunct heavy manufacturing plants, bringing new economic life and vitality to old settings.

Bob Loyd, who once oversaw crews manufacturing the last printing presses to leave the old Rockwell-Goss factory, now manages workers assembling the newest generation of giant wind turbines in the same building.

Curing Baldness Could Be A Step To Organ Regeneration

Deep roots. For a hair follicle to begin a new phase of growth, an elusive group of cells called the hair germ (bright red) must be activated. This progression of images shows that the hair germ begins proliferating (green) before other cells do, suggesting a two-step mechanism.

From The Next Big Future:

Research from Rockefeller University reveals that a structure at the base of each strand of hair, the hair follicle, uses a two-step mechanism to activate its stem cells and order them to divide. The mechanism provides insights into how repositories of stem cells may be organized in other body tissues for the purpose of supporting organ regeneration.

So understanding and fixing the stem cells and the replenishment of stem cells in hair follicles could lead to a baldness cure and also to human regeneration of organs.

Large Hadron Collider To Be Re-Started Later This Year

At Cern, the Large Hadron Collider could recreate conditions that last prevailed when the universe was less than a trillionth of a second old. Above is one of the collider's massive particle detectors, called the Compact Muon Solenoid. Valerio Mezzanotti for The New York Times

From The Telegraph:

Scientists are expected to make a decision within days on when the Large Hadron Collider, the broken "Big Bang" machine, will be re-started.

The LHC suffered a catastrophic malfunction soon after being switched on last September amid a fanfare of publicity.

Officials and scientists from the European Organization for Nuclear Research (CERN), which built the £4billion device, have been in talks this week about when to re-start it.

They have also discussed what caused the LHC to grind to a halt and how to prevent similar incidents happening in the future.

CERN have now said that they hope the machine will be up and running in time to deliver the first batch of data for experts to begin experiments by the end of the year.

A final decision on the exact date to switch it back on is expected following a meeting on Monday.

From The Guardian:

Leading scientists met last night to debate whether genetically modified crops can feed the world's hungry. The issue, it seems, is as divisive as ever

The Science Museum in London is running an exhibition until the end of May called Future Foods. It attempts to give a balanced view of the pros and cons of genetically modified crops, which are back on the agenda in the light of fears over a major food crisis. It does a good job too.

As part of the exhibition, the museum organised a debate at the Dana Centre to give the public a chance to debate GM crops and the food crisis with some key scientists. I chaired the event and picked up on a few issues I thought might be worth sharing.

Study: How Money Can Buy Happiness

From Live Science:

You've heard many times that money can't buy happiness. That probably never stopped you from shopping. But a new study suggests you might want to spend more on doing things and less on stuff.

Buying life experiences rather than material possessions leads to greater happiness for both the consumer and those around them, researchers announced today at the annual meeting of the Society for Personality and Social Psychology.

A meal out or tickets to the theater result in increased well-being because they satisfy higher order needs, specifically the need for social connectedness and vitality — a feeling of being alive, the researchers say.

"These findings support an extension of basic need theory, where purchases that increase psychological need satisfaction will produce the greatest well-being," said Ryan Howell, assistant professor of psychology at San Francisco State University.

"Noah's Flood" Not Rooted In Reality, After All?

Some believe that Noah's Ark came to rest on Turkey's Mount Ararat, above. But the ancient flood that some scientists think gave rise to the Noah story may not have been quite so biblical in proportion, a January 2009 study says. Photograph by Melik Baghdasaryan/AP/Photolur

From National Geographic:

The ancient flood that some scientists think gave rise to the Noah story may not have been quite so biblical in proportion, a new study says.

Researchers generally agree that, during a warming period about 9,400 years ago, an onrush of seawater from the Mediterranean spurred a connection with the Black Sea, then a largely freshwater lake. That flood turned the lake into a rapidly rising sea.

A previous theory said the Black Sea rose up to 195 feet (60 meters), possibly burying villages and spawning the tale of Noah's flood and other inundation folklore.

But the new study—largely focused on relatively undisturbed underwater fossils—suggests a rise of no more than 30 feet (10 meters).

From Nature:

Draft sequence opens window on human relatives.

The entire genome of a 38,000-year-old Neanderthal has been sequenced by a team of scientists in Germany. The group is already extracting DNA from other ancient Neanderthal bones and hopes that the genomes will allow an unprecedented comparison between modern humans and their closest evolutionary relative.

The three-year project, which cost about €5 million (US$6.4 million), was carried out at the Max Planck Institute for Evolutionary Anthropology in Leipzig. Project leader Svante Pääbo will announce the results of the preliminary genomic analysis at the American Association for the Advancement of Science annual meeting in Chicago, Illinois, which starts on 12 February.

Are We Bringing Our Germs to Mars?

From Time Magazine:

Star Trek fans know it as the Prime Directive: that there should be no interference with the internal affairs of other civilizations. (Given the frequency with which captains Kirk, Picard, et. al., violate it, however, the Prime Directive seems more like a Prime Suggestion.) Since human beings have yet to explore very far beyond Earth, pondering an interplanetary noninterference policy of our own may seem a little premature — at least until we've mastered warp drives and phasers.

But in fact, such a directive already exists in some form — the international Outer Space Treaty of 1967, which governs the legal framework for activities in space. Best known for banning governments from putting nuclear weapons into orbit, the treaty also requires space-faring nations to avoid "harmful contamination" of other worlds while exploring the solar system. Human beings have yet to set foot on other planets, so the risk today comes from bacteria that can hitch a ride on unmanned spacecraft like NASA's Mars Phoenix Lander, which arrived on the red planet's surface last May.

From Popular Mechanics:

As nations and regions all over the globe face too much polluted water and too little fresh water, they are turning to some of the largest, most technologically complex projects the world has ever seen. Here, we have compiled five of the biggest and most ambitious. But are they big enough to keep the taps flowing?

The dire statistics are well-known, but deserve repeating: One in six people in the world live without regular access to clean water, according to the United Nations, and one in three lacks access to decent sanitation. Even countries with good water supplies—like the U.S.—will experience trouble sustaining them in the near future, as panelists discussed at the water roundtable PM hosted last fall.

TED: Change The World With $100,000

From CBS News:

CBS Technology correspondent Daniel Sieberg is reporting from the TED conference in Long Beach, Calif.

The concept is simple; it's the execution that requires global collaboration and commitment. Not to mention some serious cash. Along those lines, TED prizes are an award of $100,000 given to a select group of recipients looking to change the world with one idea or "wish." They can use the money as they choose, and at a ceremony here Thursday night the three winners expressed their hopes for the future.

Jill Tarter, founder of SETI or the Search for Extra-Terrestrial Life, encouraged TED attendees and others to imagine ways that every "earthling" could contribute to a growing database of life beyond our planet or our "cosmic company." In real terms, Tarter wants kids to be more involved in the experience of searching or studying the universe, and improve the way information from space is stored and shared with astronomers. Her announcement was preceded by a taped introduction from Sir Richard Branson, who is actively pursuing commercial space travel through his Virgin Galactic project.

Top 5 Most Extreme Exoplanets

From Wired Science:

Searching for planets beyond our solar system is a bit like playing Goldilocks — we keep looking for that one that will be just right to host life. While astronomers haven't found a perfect fit yet, they have found plenty that are too big, too hot, too cold, too dense, too close to their star, or too distant.

The first exoplanet discovery was in 1988, though it was controversial at the time and wasn't officially confirmed until 2003. Over the years, more than 330 extrasolar planets have been found, nearly all of them using indirect methods such as detecting the wobble of a star due to the gravitational pull of an orbiting planet or the slight dimming of the star's light as a planet passes in front of it.

Key Insights Into How New Species Emerge

From Science Digest:

ScienceDaily (Feb. 6, 2009) — A team of researchers are reporting the ongoing emergence of a new species of fruit fly--and the sequential development of a new species of wasp--in the February 6 issue of the journal Science.

Jeff Feder, a University of Notre Dame biologist, and his colleagues say the introduction of apples to America almost 400 years ago ultimately may have changed the behavior of a fruit fly, leading to its modification and the subsequent modification of a parasitic wasp that feeds on it.

The result is a chain reaction of biodiversity where the modification of one species triggers the sequential modification of a second, dependent species.

"It's a nice demonstration of how the initial speciation of one organism opens up an opportunity for another species in the ecosystem to speciate in kind," said Feder. "Biodiversity in essence is the source for new biodiversity."

Reading This Will Change Your Brain

From Newsweek:

A leading neuroscientist says processing digital information can rewire your circuits. But is it evolution?

Is technology changing our brains? A new study by UCLA neuroscientist Gary Small adds to a growing body of research that says it is. And according to Small's new book, "iBRAIN: Surviving the Technological Alteration of the Modern Mind," a dramatic shift in how we gather information and communicate with one another has touched off an era of rapid evolution that may ultimately change the human brain as we know it. "Perhaps not since early man first discovered how to use a tool has the human brain been affected so quickly and so dramatically," he writes. "As the brain evolves and shifts its focus towards new technological skills, it drifts away from fundamental social skills."

How You Can Tell A Person's Class: The Wealthy Fidget, Yawn And Generally Appear Rude, Say Researchers

Photo: Body language: Those from wealthier backgrounds tend to appear more distracted than their less well off counterparts

From The Daily Mail:

Fidgeting, yawning and doodling have long been equated with boredom.

But if the person you're speaking to isn't paying attention, they may be rich rather than rude, a study has revealed.

It found that posh people fidget more - making it possible to tell a person's social class by their body language.

Researchers said those born into privilege may feel less of a need to make a good impression and so are more inclined to fidget when talking to other people.

In contrast, their poorer counterparts are anxious to make a good impression and so are more attentive.

From International Herald Tribune:

Forensic evidence that has helped convict thousands of defendants for nearly a century is often the product of shoddy scientific practices that should be upgraded and standardized, according to accounts of a draft report by the nation's pre-eminent scientific research group.

The report by the National Academy of Sciences is to be released this month. People who have seen it say it is a sweeping critique of many forensic methods that the police and prosecutors rely on, including fingerprinting, firearms identification and analysis of bite marks, blood spatter, hair and handwriting.

Britannica 2.0 Shows Wikipedia How It's Done

From Times Online:

The 240-year-old Encyclopaedia Britannica has taken a giant leap into the world of Web 2.0 with the launch of a new online version where users can contribute and edit content.

In a move that takes it head to head with Wikipedia, new features on the Britannica site will allow users to edit and contribute articles in return for the glory of having their name attached to the submission.

However, “voyeuristic” Wikipedia fans ought not to get too excited by the changes as all submissions will undergo a strict vetting process and may or may not make the cut, according to Britannica 's president, Jorge Cauz.

“We’re not trying to be a wiki - that’s the last thing we want to be,” Mr Cauz told The Times.

From China View:

SHANGHAI, Feb.1 (Xinhua) -- East Asian astronomers are building the world's largest radio telescope array to see the deep into the galaxy and black holes and more accurately determine the orbits of lunar probes such as China's Chang'e-1.

The array, called the East Asia Very Long Baseline Interferometry (VLBI) consortium, consists of 19 radio telescopes from China, Japan and the Republic of Korea (ROK) that cover an area with a diameter of 6,000 kilometers from northern Japan's Hokkaido to western China's Kunming and Urumqi.

The VLBI technology is widely used in radio astronomy. It combines the observations simultaneously made by several telescopes to expand the diameter and increase magnification.

Google Inc. and two nonprofit partners Wednesday launched a Web site that lets consumers test their Internet connections to reveal possible interference and traffic management by service providers.

The site, Measurement Lab, addresses a need among academics who want to gather data on how Internet connections work in practice. While the workings of the core Internet "highways" are well known and standardized, it's difficult to find out what happens on the network of an Internet service provider, between the "highway" and the customer's home.
