Filipinos Draw Power From Buried Heat -- Washington Post

ORMOC, Philippines -- Ferdinand Marcos, the despot who ruled here for 21 years, is remembered mainly for the staggering quantity of his wife's shoes. But there is another Marcos legacy, and it is drawing new attention at a time of high oil prices, global warming and urgent questions about the role of government in alternative energy development.

Reacting to the early 1970s oil shock, Marcos created a major government program to find, develop and generate electricity from hot rocks deep in the ground. Since then, the Philippine government has championed this form of energy.

Geothermal power now accounts for about 28 percent of the electricity generated in the Philippines. With 90 million people, about 40 percent of whom live on less than $2 a day, this country has become the world's largest consumer of electricity from geothermal sources. Billions of dollars have been saved here because of reduced need for imported oil and coal.

See A Pattern On Wall Street?

From The New York Times:

Take a look at the two blurry images below. Can you see an object hidden in each one?

Before I give the answers, here’s another question: Do you feel a certain lack of control over events right now?

These questions are not unrelated, according to a report in the new issue of Science by Jennifer Whitson and Adam Galinsky. The researchers found that when people were primed to feel out of control, they were more likely to see patterns where none exist. They would spot an object in each of the images above, even though only the image on the right contains one (the outline of Saturn and its rings). If you thought you saw something in the image on the left, don’t be too hard on yourself — your feeling may be perfectly understandable given the chaos on Wall Street.

New Jersey Grants Rights to Build a Wind Farm About 20 Miles Offshore -- New York Times

Regulators in New Jersey awarded the rights on Friday for construction of a $1 billion offshore wind farm in the southern part of the state to Garden State Offshore Energy. The rights, which include access to as much as $19 million in state grants, is part of New Jersey’s Energy Master Plan, which calls for 20 percent of the state’s energy to come from renewable sources by 2020. The decision comes on the heels of decisions by Delaware and Rhode Island to allow the installation of offshore wind farms.

Energy experts say that these approvals could prompt regulators in New York to support projects off the south shore of Long Island and New York City.

Garden State Offshore Energy is a joint venture that includes P.S.E.G. Renewable Generation, a subsidiary of P.S.E.G. Global, which is a sister company of the state’s largest utility, Public Service Electric and Gas Company.

The proposal by Garden State Offshore Energy includes the installation of 96 turbines to produce as much as 346 megawatts of electricity, enough to power tens of thousands of houses, starting in 2013. The turbines would be arranged in a rectangle about a half-mile long by one-third of a mile wide and would be placed 16 to 20 miles off the coast of New Jersey’s Atlantic and Ocean Counties, much farther out and in much deeper water than other proposed wind farms. Deepwater Wind, which will work with P.S.E.G. to build the wind farm, said it could affordably build turbines in 100 feet of water with the same technology used to build oil and gas rigs in the Gulf of Mexico and other places.

China And Smoking Go Hand In Hand

China Lung Disease 'To Kill 83m' -- BBC News

A US study has suggested that more than 80 million people in China will die in the next 25 years as a result of lung disease.

The research says the vast majority of those premature deaths are preventable.

The study focused on the devastating impact of smoking and the widespread practice of burning wood or coal at home for cooking and heating.

The Harvard School of Public Health research looked at a 30-year period, spanning the last five and the next 25.

Respiratory disease is already a leading cause of deathChi in China, but this latest study suggests a startling rise.

In the 30-year period, it calculates, about 83 million Chinese people will die prematurely of lung disease.

From Science Daily:

ScienceDaily (Oct. 3, 2008) — Supporting what many of us who are not musically talented have often felt, new research reveals that trained musicians really do think differently than the rest of us. Vanderbilt University psychologists have found that professionally trained musicians more effectively use a creative technique called divergent thinking, and also use both the left and the right sides of their frontal cortex more heavily than the average person.

The research by Crystal Gibson, Bradley Folley and Sohee Park is currently in press at the journal Brain and Cognition.

"We were interested in how individuals who are naturally creative look at problems that are best solved by thinking 'out of the box'," Folley said. "We studied musicians because creative thinking is part of their daily experience, and we found that there were qualitative differences in the types of answers they gave to problems and in their associated brain activity."

Grief: The Price of Love

Old Man Crying (Photo from Trekearth)

From Live Science:

Years ago while observing a troop of Barbary macaques for behavioral research, I was surprised to see a new mother holding on to her obviously stillborn baby. She clutched the corpse to her chest and made soft cooing sounds, obviously in distress.

More remarkable, she held on to that dead baby for more than a week as it began to decompose.

Eventually, the mother showed up alone, but then it got even sadder. She began to haunt other mothers, those with live babies. She would sit close to them and try to grab those babies and hug them, as if to make up for her loss.

I was clearly witnessing a mother in deep grief, and I felt great empathy.

After all, she had been stuck in an evolutionarily dilemma that all of us, at one time or another, experience. Monkey, apes, humans and all other social animals are born to attach to others because those connections help keep us alive and up the chances of passing on genes. But at the same time, we pay dearly for that advantage when our loved ones leave.

From Discover:

Aug. 22, 2008 -- The world's first known modern human was a tall, thin individual -- probably male -- who lived around 200,000 years ago and resembled present-day Ethiopians, save for one important difference: He retained a few primitive characteristics associated with Neanderthals, according to a series of forthcoming studies conducted by multiple international research teams.

The extraordinary findings, which will soon be outlined in a special issue of the Journal of Human Evolution devoted to the first known Homo sapiens, also reveal information about the material culture of the first known people, their surroundings, possible lifestyle and, perhaps most startling, their probable neighbors -- Homo erectus.

"Omo I," as the researchers refer to the find, would probably have been considered healthy-looking and handsome by today's standards, despite the touch of Neanderthal.

French Bees Find A Haven In Paris


From The International Herald Tribune:

Corinne Moncelli offers guests at her Eiffel Park Hotel more than a view of the Paris landmark. She serves them honey from bees she keeps on the rooftop.

There are more than 300 known colonies in the French capital, up from about 250 five years ago, according to the National Beekeepers' Association. Hives have appeared on the roof of the Opéra Garnier, on balconies and in parks.

Bees are thriving in cities because "flowers and plants are changed constantly and there aren't pesticides," said Moncelli, who co-owns the hotel with her husband, Pascal.

Old Violins Reveal Their Secrets

(Photo from Nashville Violins)

From Nature:

Acoustic measurements identify the signature of a Stradivarius.

Why do the violins made by Stradivari and Guarneri del Gesù sound so good? Countless theories have been proposed for the secret of these eighteenth-century Italian instrument-makers, but attempts to identify a unique acoustic signature have proved fruitless. Now a study has finally identified a measurable sound quality that distinguishes these old violins from cheap, factory-made instruments.

After spending ten years painstakingly measuring the acoustics of violins rated from "bad" to "excellent" by professional musicians, George Bissinger of East Carolina University in Greenville, North Carolina, says that the 'excellent' old Italian violins in his sample show a significantly stronger acoustic response in the lower octaves than do the 'bad' violins, whereas those rated merely 'good' have intermediate values1. The high-quality tone is caused by a single mode of vibration of air inside the body, which radiates sound strongly through the violin's f-holes.

The Beginning of E-Paper?

Scientists Aim To Deliver E-Paper In Full
Computerised Colour -- The Guardian


Scientists in Cambridge have launched a £12m three-year project to create the next generation of e-paper, which may herald the arrival of fully interactive, all-colour computerised newspapers and magazines.

Liquavista, spun out of the Philips Research Labs in Eindhoven two years ago, has won part of the backing from the government-funded Technology Strategy Board. The project is also backed by Plastic Logic. The US technology company last month unveiled a prototype e-paper that looks much more like a sheet of A4 than the offerings of rivals such as Amazon's Kindle and Sony eReader, which resemble paperback books.

But Plastic Logic's device is only black and white, not very flexible and its screen updates quite slowly. Liquavista is working on a full-colour flexible screen that would allow newspapers and other publications to give their audience a much more interactive product that could include video.

Tuberculosis: An Ancient Disease Continues to Thrive
-- Time Magazine


The Church of Scotland Hospital in Tugela Ferry, South Africa, sits in an arid valley among the mountains of KwaZulu-Natal. Occupying a dozen or so tin-roofed, low-slung buildings, the hospital serves its rural patients well: Women come to have babies, H.I.V. patients register to receive their medications, and those infected with tuberculosis check in for a chance to recover from an ancient scourge.

But in 2005 a physician noticed that some of those TB patients, many of whom were H.I.V.-positive, were not getting any better, despite being on anti-TB medications. Nothing he provided them seemed to control the tubercle bacillus flourishing in their bodies. Of the 53 who were sickest, 52 died, most within a month of entering the hospital.

The Miracle Machine That Turns Cheap Plonk Into Vintage Wine - In Just Half An Hour -- The Daily Mail

A device that claims to turn cheap supermarket plonk into vintage wine and banish hangovers is set to hit the high street.

Inventors say a bottle of any bargain booze can be transformed in just 30 minutes, using space-age ultrasound technology.

The £350 gadget - which looks like an ordinary ice bucket - recreates the effects of decades of aging by colliding alcohol molecules inside the bottle.

Dragons Den veteran, entrepreneur and inventor Casey Jones, 53, is the man behind the machine, which is yet to be given a retail name.

He said: 'This machine can take your run-of-the-mill £3.99 bottle of plonk and turn it into a finest bottle of vintage, tasting like it's hundreds.

'It works on any alcohol that tastes better aged. Even a bottle of paint-stripper whisky can taste like an 8-year-aged single malt.'

Mr Jones is now in talks with leisure chain Hotel Du Vin about marketing the working-titled 'Ultrasonic Wine Ager'.

Warming To Spur Potato Famine In The Andes?


From National Geographic:

When Tito Guillen Rosales was a young boy, his grandfather was a rich man, growing 50 bags of potatoes a year and sharing his surplus with community members who didn't have enough.

"But now his potatoes are covered with worms and plagues and he barely has enough to feed himself," said Rosales, 27, a farmer himself and the mayor of a Peruvian village at 11,000 feet (3,353 meters) in the Cordillera Blanca range of the Andes mountains.

"We are all becoming desperate to find a solution to the changes in the weather and climate that have brought these new pests," Rosales said.

Here in the Andean highlands scientists attribute warmer temperatures and shifting precipitation patterns to global climate change. These shifts are seriously affecting the health of tuber, or root, crops such as the potato.

Late blight, a fungus responsible for the Irish potato famine in the 1800s, appeared for the first time in Coyllurqui sometime in the last 20 years, surprising and flummoxing farmers such as Rosales and his grandfather.

Branson Wants to Help Science Save Earth

(Photo: Wired Magazine)

From Wired News:

Richard Branson has slapped the Virgin name on everything from airlines and space travel to record stores and comic books, and now he wants to add scientific research into global climate change.

The flamboyant British entrepreneur says his fledgling Virgin Galactic enterprise will use the Space Ship Two and White Knight Two (pictured) vehicles to carry research equipment to the highest levels of the atmosphere for a research project planned by the National Oceanic and Atmospheric Administration. The instruments will provide vast quantities of data regarding atmospheric conditions, particularly the level of carbon dioxide, methane and other greenhouse gases, and allow the agency to calibrate measurements made by satellites.

"We need data and observations to understand how our climate changes," Conrad Lautenbacher, the agency's administrator, said in a statement. "This affords us a new and unique opportunity to gather samples and measurements at much higher altitudes than we can usually achieve."

Such a partnership would solve one of the NOAA's biggest challenges with atmospheric research -- it doesn't have anything capable of reaching such lofty altitudes.

Ask the Brains: Why Do We Laugh When Someone Falls?

Alexander Hafemann/iStockPhoto

From Scientific America:

Why do we find it funny when some­one falls down?
—William B. Keith, Houston

William F. Fry, a psychiatrist and laughter researcher at Stanford University, explains:

Every human develops a sense of humor, and everyone’s taste is slightly different. But certain fundamental aspects of humor help explain why a misstep may elicit laughter.

The first requirement is the “play frame,” which puts a real-life event in a nonserious context and allows for an atypical psychological reaction. Play frames explain why most people will not find it comical if someone falls from a 10-story building and dies: in this instance, the falling person’s distress hinders the establishment of the nonserious context. But if a woman casually walking down the street trips and flails hopelessly as she stumbles to the ground, the play frame may be established, and an observer may find the event amusing.

The Element That Could Change The World

From Discover Magazine:

Making green energy work may depend on three unlikely heroes: an Australian engineer, a battery, and the element vanadium.

February 27, 2008, was a bad day for renewable energy. A cold front moved through West Texas, and the winds died in the evening just as electricity demand was peaking. Generation from wind power in the region rapidly plummeted from 1.7 gigawatts to only 300 megawatts (1 megawatt is enough to power about 250 average-size houses). The sudden loss of electricity supply forced grid operators to cut power to some offices and factories for several hours to prevent statewide blackouts.

By the next day everything was back to normal, but the Texas event highlights a huge, rarely discussed challenge to the adoption of wind and solar power on a large scale. Unlike fossil fuel plants, wind turbines and photovoltaic cells cannot be switched on and off at will: The wind blows when it blows and the sun shines when it shines, regardless of demand. Even though Texas relies on wind for just over 3 percent of its electricity, that is enough to inject uncertainty into the state’s power supplies. The problem is sure to grow more acute as states and utilities press for the expanded use of zero-carbon energy. Wind is the fastest-growing power source in the United States, solar is small but also building rapidly, and California is gearing up to source 20 percent of its power from renewables by 2017.

The Power Of Pond Scum

From CBS:

(CBS) Set amid cornfields and cow pastures in eastern Holland is a shallow pool that is rapidly turning green with algae, harvested for animal feed, skin treatments, biodegradable plastics - and with increasing interest, biofuel.

In a warehouse 120 miles southwest, a bioreactor of clear plastic tubes is producing algae in pressure-cooker fashion that its manufacturer hopes will one day power jet aircraft.

Experts say it will be years, maybe a decade, before this simplest of all plants can be efficiently processed for fuel. But when that day comes, it could go a long way toward easing the world's energy needs and responding to global warming.

Algae is the slimy stuff that clouds your home aquarium and gets tangled in your feet in a lake or ocean. It can grow almost everywhere there is water and sunlight, and under the right conditions it can double its volume within hours. Scientists and industrialists agree that the potential is huge.

UK Urged To Fund Climate Project

From The BBC:

The UK government has been urged to fund the next stage of a major European programme to monitor the effects of global climate change from space.

The trade body UKspace made the call ahead of a key ministerial meeting.

Britain entered Kopernikus, the world's biggest environmental monitoring project, at a quarter of the funding level preferred by industry.

UK companies are understood to have lost out on lucrative contracts as a result.

The programme will combine data from state-of-the-art satellites and hundreds of other sources to provide an accurate understanding of the land, oceans and atmosphere.

10 Future Shocks For The Next 10 Years

From InfoWorld:

As InfoWorld turns 30, a look back at the changes wrought by technology since 1978 boggles the mind. The extended InfoWorld family predicts the shocking developments we can expect between now and 2018

The past 30 years of InfoWorld's existence have seen a series of future shocks, from the ascent of the personal computer to horrifying strains of malware to the sizzling sex appeal of the iPhone. In honor of InfoWorld's 30th anniversary, we've decided to take a playful look ahead at the future shocks that could occur in the next 10 years (30 years seemed a little too sci-fi).

An all-points bulletin went out to InfoWorld contributors, the replies to which we culled into 10 future shocks -- ranging from radical changes in IT's responsibility to "1984"-ish scenarios where privacy is a quaint notion. No doubt you've considered many of these possibilities yourself. Even more likely, you have just as many interesting scenarios to bring to the party, and we urge you to share them in the comments section of this article. Dream big -- given the drama of the past 30 years, the next 10 are anyone's guess.
