Babies Know Happy From Sad Songs

(Photo from Baby Pictures Photos)

From Live Science:

Babies as young as 5 months can distinguish an upbeat tune, such as "Ode to Joy" from Beethoven's Ninth Symphony, from a lineup of gloomy tunes.

Researchers displayed an emotionally-neutral face for the baby while sad music played. When the baby looked away from the face, the music stopped and a new sad song would start. When the happier "Ode to Joy" played, the babies stared at the face three to four seconds longer, suggesting they were interested in the shift.

By 9 months old, babies can do the opposite, picking out the sorrowful sound of Beethoven's Seventh Symphony from a pack of happy pieces.

The finding is another example of how babies make sense of the world long before they can talk, said Brigham Young University psychology professor and study author Ross Flom.

Blood Test Finds Coronary Disease

(Photo from NHLBI)

From The New Observer:

A simple blood test could soon replace expensive and invasive exams to detect coronary artery disease.

The test, announced Wednesday by doctors at Duke, is being developed after the discovery of genetic markers that show the presence and intensity of blockage in coronary artery disease, said a Duke cardiologist who co-authored research on the link.

Such a blood test could save millions of dollars annually by allowing some patients to avoid risky procedures in which catheters are inserted into patients' arteries.

"I think it is a big deal," Dr. William E. Kraus, a Duke cardiologist, said in an interview Wednesday. "What we want is a test that tells us the status of your disease today and if what you have is heart disease." Kraus' research was published in the medical journal Circulation: Cardiovascular Genetics.

Current detection of the disease -- the leading cause of death in the United States and a top killer in North Carolina, with 23,610 deaths in 2006 -- can require expensive tests such as echocardiograms, stress tests and imaging techniques that use radiation.

"A blood-based test to diagnose coronary artery disease would be less invasive and risky and would prevent patients from [receiving] radiation exposure," Kraus said in a statement.

In Puppy Play, It's Ladies First

She's the Boss: During puppy play, young males sometimes put themselves in a position where they can be taken advantage of by their female playmates. The early behavior could serve them well later in life, say researchers. (Photo: From Discovery)

From Discovery:

Oct. 9, 2008 -- It may not be such a dog-eat-dog world after all, at least among puppies. A new study has found that young male dogs playing with female pups will often let the females win, even if the males have a physical advantage.

Male dogs sometimes place themselves in potentially disadvantageous positions that could make them more vulnerable to attack, and researchers suspect the opportunity to play may be more important to them than winning.

Such self-handicapping has been documented before in red-necked wallabies, squirrel monkeys, hamadryas baboons and even humans, all of which frequently take on defensive positions when playing with youngsters, in particular.

The gentlemanly dog behavior is even accompanied with a bow.

From Christian Science Monitor:

Worldwide computer grids mean even small-timers can contribute to ‘big science.’

Elizabeth City State University in North Carolina is not the first name that pops up in conversations about centers of polar science.

Tucked at the tip of a branch of Albemarle Sound, along the state’s northeast coast, the well-regarded, historically African-American university focuses largely on undergraduate education. But it’s also taking part in cutting-edge Arctic and Antarctic science as a key player in PolarGrid – a powerful, sophisticated computer network researchers use to analyze images of ice sheets in Greenland and Antarctica and model their behavior.

It’s part of the burgeoning world of e-Science – a realm where the questions are big, cutting across once-disparate disciplines. And the answers often demand enormous amounts of number crunching through networks of interconnected computing centers at universities and laboratories around the world – a process known as grid computing.

From CNN:

CAMBRIDGE, England (CNN) -- Professor Stephen Hawking, one of the world's great scientists, is looking to the stars to save the human race -- but pessimism is overriding his natural optimism.

Hawking, in an exclusive CNN interview, said that if humans can survive the next 200 years and learn to live in space, then our future will be bright.

"I believe that the long-term future of the human race must be in space," said Hawking, who is almost completely paralyzed by the illness ALS.

"It will be difficult enough to avoid disaster on planet Earth in the next 100 years, let alone next thousand, or million. The human race shouldn't have all its eggs in one basket, or on one planet. Let's hope we can avoid dropping the basket until we have spread the load."

Hawking is one of the few scientists known to a wide audience outside academia thanks to his best-selling books, a guest spot on "The Simpsons" and an ability to clearly explain the complexities of theoretical physics.

Prize Won For Subatomic Theories In Field Of Elementary Particle Physics

(AP) Two Japanese citizens and an American won the 2008 Nobel Prize in physics for discoveries in the world of subatomic physics, the Royal Swedish Academy of Sciences announced Tuesday.

American Yoichiro Nambu, 87, of the University of Chicago, won half of the prize for the discovery of a mechanism called spontaneous broken symmetry. Makoto Kobayashi and Toshihide Maskawa of Japan shared the other half of the prize for discovering the origin of the broken symmetry that predicts the existence of at least three families of quarks in nature.

In its citation, the academy said that this "year's Nobel laureates in physics have presented theoretical insights that give us a deeper understanding of what happens far inside the tiniest building blocks of matter."

Turning to Nambu, it said that his work in "Spontaneous broken symmetry conceals nature's order under an apparently jumbled surface," the academy said in its citation. "Nambu's theories permeate the Standard Model of elementary particle physics. The model unifies the smallest building blocks of all matter and three of nature's four forces in one single theory."

Three Chemists Win Nobel Prize -- New York Times

One Japanese and two American scientists won this year’s Nobel Prize in Chemistry on Wednesday for taking the ability of some jellyfish to glow green and transforming it into a ubiquitous tool of molecular biology to watch the dance of living cells and the proteins within them.

Osamu Shimomura, an emeritus professor at the Marine Biological Laboratory in Woods Hole, Mass. and Boston University Medical School, Martin Chalfie of Columbia University, and Roger Y. Tsien of the University of California, San Diego, will share the $1.4 million prize awarded by the Royal Swedish Academy of Sciences.

The green fluorescent protein, or G.F.P. for short, was observed in 1962 in the jellyfish Aequorea victoria, which drifts in the ocean currents off the west coast of North America.

Dr. Shimomura was able to identify the protein and showed that it glowed bright green under ultraviolet light.

Dr. Chalfie showed how the protein could be used as a biological identifier tag by inserting the gene that produces the protein into the DNA of an organism.

'Unbreakable' Encryption Unveiled

From The BBC:

Perfect secrecy has come a step close with the launch of the world's first computer network protected by unbreakable quantum encryption at a scientific conference in Vienna.

The network connects six locations across Vienna and in the nearby town of St Poelten, using 200 km of standard commercial fibre optic cables.

Quantum cryptography is completely different from the kinds of security schemes used on computer networks today.

These are typically based on complex mathematical procedures which are extremely hard for outsiders to crack, but not impossible given sufficient computing resources or time.

But quantum systems use the laws of quantum theory, which have been shown to be inherently unbreakable.

Asteroid Near-Miss Prompts Calls For Astronomy Funding

Scientists say the world has been 'lucky' no asteroids have crashed into the earth in recent years.
(Reuters: NASA)

From ABC News (Australia):

Astronomers have calling for more funding to watch southern skies, after an asteroid took sky-gazers by surprise and entered the earth's atmosphere over Africa yesterday.

Yesterday morning astronomers in Arizona reported seeing a tiny asteroid, which they described as a new but routine fast-moving object.

Before long, scientists at the International Astronomical Union's Minor Planet Center (MPC) in Massachusetts had calculated the object was likely to pass within one Earth's radius of the centre of the planet.

That means it would have struck the surface of the Earth if had been big enough.

Gareth Williams, associate director of the MPC, spoke to AM shortly before the asteroid entered the earth's atmosphere.

"We estimate that it's about two metres across with a probable range of one to five metres. Something that small will not survive passage through the atmosphere intact," he predicted.

DNA Could Reveal Your Surname -- Science Daily

ScienceDaily (Oct. 8, 2008) — Scientists at the Department of Genetics at the University of Leicester – where the revolutionary technique of genetic fingerprinting was invented by Professor Sir Alec Jeffreys -- are developing techniques which may one day allow police to work out someone's surname from the DNA alone.

Doctoral research by Turi King has shown that men with the same British surname are highly likely to be genetically linked. The results of her research have implications in the fields of forensics, genealogy, epidemiology and the history of surnames.

On Wednesday 8th October Dr King will present the key findings of her Ph.D. research in which she recruited over two and a half thousand men bearing over 500 different surnames to take part in the study. Carried out in Professor Mark Jobling's lab, Dr Turi King's research involved exploring this potential link between surname and Y chromosome type.

Why Tokyo Gets Bad Earthquakes

What Is Giving Tokyo A Headache? -- IOL

Paris - A massive slab of rock lurking beneath the Kanto Plain on the central Japanese island of Honshu is a major source of the earthquake threat that dogs Tokyo, scientists said on Sunday.

Around 100 kilometres wide and 25km thick, the chunk is jammed between tectonic plates that converge beneath the flat, densely-populated plain.

The giant fragment is a potent trigger for a hugely destructive kind of quake, for it wedges between two of the plates and prevents them from sliding smoothly over one other.

As a result, tensions build up until the stored energy is released catastrophically, rather than in smaller, safer movements, the experts say.

Tokyo is built atop the Eurasian plate, one of the two dozen or so tectonic plates that, like jostling pieces on a jigsaw puzzle, comprise earth's surface.

Around 100km to the northwest of the city, on the Kanto Plain, the local geology becomes complex, turning into a triple-layer subterranean sandwich.

Death, A Cultural And Historical Look

Death Rituals Reveal Much About Ancient Life -- Live Science

Cultures around the world and through time have had wildly varying ways of dealing with the dead. And since death weighs so heavy on a culture and is ultimately so mysterious, records of these practices, or "deathways," are often more abundant than other ancient cultural accounts and provide illuminating windows into other cultures.

"Deathways illuminate religious meaning and the social life of cultures about which we may know little else," says Erik Seeman, Ph.D., associate professor of history at the University at Buffalo and author of the forthcoming "Death in the New World."

Cremation, grave cairns, funeral mounds, mummification, air burial, and belief in life after death are just some of the practices which, though sacred to one culture, often seem odd or even terrifying to another, Seeman says. The Greeks, for example, were fascinated with the historian Herodotus' description of the ancient Issedonians chopping up their dead into a mixed grill and devouring them in a communal barbeque, something entirely contrary to the Greeks' treatment of their own dead.

"Much of my research looks at how deathways marked cultural self-definition and the definition of 'other' in the New World," Seeman said.

Stars Stop Forming When Big Galaxies Collide

(Photo from National Geographic)

From e! Science News:

Astronomers studying new images of a nearby galaxy cluster have found evidence that high-speed collisions between large elliptical galaxies may prevent new stars from forming, according to a paper to be published in a November 2008 issue of The Astrophysical Journal Letters. Led by Jeffrey Kenney, professor and chair of astronomy at Yale, the team saw a spectacular complex of warm gas filaments 400,000 light-years-long connecting the elliptical galaxy M86 and the spiral galaxy NGC 4438 in the Virgo galaxy cluster, providing striking evidence for a previously unsuspected high-speed collision between the galaxies. The view was constructed using the wide-field Mosaic imager on the National Science Foundation telescope at Kitt Peak National Observatory near Tucson, Arizona.

"Our data show that this system represents the nearest recent collision between a large elliptical galaxy and a large spiral galaxy," said Kenney, who is lead author of the paper. "This discovery provides some of the clearest evidence yet for high-speed collisions between large galaxies, and it suggests a plausible alternative to black holes as an explanation of what turns off star formation in the biggest galaxies."

Ozone Hole Grows In 2008 -- CNN

(CNN) -- The ozone hole over Antarctica in 2008 is larger in both size and ozone loss than last year, but not as large as in 2006, the European Space Agency said Tuesday.

The hole is a thinning area in the ozone layer over Antarctica and the size of the hole varies every year depending on weather conditions.

This year, the size of the thinned area reached about 27 million square kilometers (10.4 million square miles), compared to 25 million square kilometers (9.65 million square miles) in 2007.

In 2006, the hole was a record 29 million square kilometers (11.2 million square miles), larger than North America, the ESA said.

The ESA announced its results based on information from German and Dutch researchers who analyzed satellite data.

Depletion of ozone is caused by extreme cold temperatures at high altitude and the presence of ozone-destroying gases, such as chlorine and bromine, in the atmosphere, the ESA said.

Those gases originate from man-made products like chlorofluorocarbons, or CFCs, which were phased out under a global agreement two decades ago but continue to linger in the atmosphere.

Ozone is a protective atmospheric layer found at an altitude of about 25 kilometers (15.5 miles).

It acts as a sunlight filter, shielding life on Earth from harmful ultraviolet rays that put humans at greater risk of skin cancer and cataracts and harm marine life, the agency said.

How Much Oil is Actually Left On This Planet? Should We Care?

From Gas2.0:

According to Dr. Peter McCabe, a world-renowned scientist currently working at CSIRO in Australia, any realistic analysis of future energy sources can only conclude that, barring some complete and miraculous harmony between all the world’s economic superpowers, fossil fuels will dominate our energy mix for at least the next few decades — and we should just accept it.

To get a perspective on where Dr. McCabe is coming from, it struck me that he is a man who thinks in terms of quadrillions of BTUs and exajoules of energy. His views come from an analysis of global markets and global energy use. To him it probably seems that a grassroots coordinated global effort is beyond the reach of humanity.

Being a bit of a realistic skeptic myself, it seemed like it would be worth my while to temporarily suspend my deep held belief that not only is it possible for the U.S. and most of the rest of the world to kick its oil habit within a decade, but also a simple requirement for survival, and take Dr. McCabe at face value.

Cosmic Eye Looks Back In Time To Picture A Galaxy Forming In The Early Universe

Back in time: A young, star-forming galaxy as it appeared two billion years after the Big Bang, as pictured by the Cosmic Eye. (Photo from Daily Mail)

From The Daily Mail Online:

Scientists have used a Cosmic Eye to 'look back in time' and glimpse a galaxy formation in the early Universe.

Using gravity from a galaxy in the foreground as an enormous zoom lens, researchers were able to see into the distant Universe.

The Cosmic Eye allowed scientists to observe a young star-forming galaxy, which lies about 11 billion light years from Earth, as it appeared just two billion years after the Big Bang.

Teams from the California Institute of Technology (Caltech) in the US and Durham and Cardiff Universities in the UK believe their findings show for the first time how the galaxy might evolve to become a spiral system like the Milky Way.

The Cosmic Eye is so called because the foreground galaxy, which is 2.2 billion light years from Earth, appears in the centre of an arc created by the distant galaxy - giving it the appearance of a human eye.

Its name also derives from its resemblance to the Eye of Horus, the ancient Egyptian symbol representing the god of the sky and the ruler of the world of the living.

The distant galaxy was originally identified using the Hubble Space Telescope.

Scientists then used the 10 metre Keck telescope, in Hawaii, along with the magnifying effect of the gravitational field of the foreground galaxy to enlarge the distant galaxy by eight times.

"Deadly Dozen" Diseases Could Stem From Global Warming

(Photo from National Geographic)

Tick populations will shift as a result of climate change, bringing Lyme disease to new regions and infecting more animals and people. An October 2008 study suggests that global warming will lead to new outbreaks of other dangerous diseases as well.

From National Geographic:

A spike in deadly infectious diseases in wildlife and people may be the "most immediate consequence" of global warming, according to a new report released today.

Dubbed the "deadly dozen," sicknesses such as Lyme disease, yellow fever, plague, and avian influenza, or bird flu, may skyrocket as global shifts in temperature and precipitation transform ecosystems.

Babesia, cholera, ebola, intestinal and external parasites, red tides, Rift Valley fever, sleeping sickness and tuberculosis round out the list. (Read descriptions.)

An "early warning system" based on an international wildlife-monitoring network may be the only effective defense, said William Karesh, a report co-author and vice president of Global Health Programs at the New York-based Wildlife Conservation Society.

How Do Bloggers Make Money?

Blogging For Dollars -- Slate

Last week, the blog search engine Technorati released its 2008 State of the Blogosphere report with the slightly menacing promise to "deliver even deeper insights into the blogging mind." Bloggers create 900,000 blog posts a day worldwide, and some of them are actually making money. Blogs with 100,000 or more unique visitors a month earn an average of $75,000 annually—though that figure is skewed by the small percentage of blogs that make more than $200,000 a year. The estimates from a 2007 Business Week article are older but juicier: The LOLcat empire rakes in $5,600 per month; Overheard in New York gets $8,100 per month; and Perez Hilton, gossip king, scoops up $111,000 per month.

With this kind of cash sloshing around, one wonders: What does it take to live the dream—to write what I know, and then watch the money flow?

The region in the foreground near the right side of the imag is close to the border between darkness and daylight, so shadows are long and prominent. Two very long scarps are visible in this region, and the scarps appear to crosscut each other. The easternmost scarp also cuts through a crater, showing that it formed after the impact that created the crater.

Large Hadron Collider Broke Down Because Of Bad Soldering On A Single Connection -- Daily Telegraph

The £4.4 billion Large Hadron Collider was put out of action for months because one electrical connection out of 10,000 was badly soldered, the experiment's chief scientist said.

"It is very probable that there was a connection that wasn't good," said Lyn Evans, project leader of the 17-mile LHC, buried deep under Swiss soil at CERN, the European Nuclear Research Organisation.

The LHC, which aims to shed light on how the universe began by replicating conditions just after the Big Bang, has to operate at extremely cold temperatures.

It was switched on to great fanfare on Sep 10, but had to be turned back off nine days later because the cooling mechanism broke.

It takes weeks to rechill the machine to "superconducting" temperatures - allowing it to fire protons around a 17 mile loop of tunnels, causing them to crash into one another at close to light speed and break into even tinier particles

Mr Evans said he did not think a single fault in 10,000 connections was bad, but "it cost dearly".

Puzzling Over Pre-Humans -- Cosmic Log/MSNBC

The world’s best-known skeleton of a human ancestor - whose name, "Lucy," came from a Beatles song - now lies splayed out in Seattle's Pacific Science Center like ornaments in a glass jewelry case. Or, more aptly, like 3.2-million-year-old pieces of a jigsaw puzzle.

Anthropologists are still working on the puzzles about human origins that have been posed by Lucy and other fossils, including a major find that was made just a couple of miles away from the place where Lucy was found 34 years ago.

The long-running mystery surrounding the "First Family" - a grouping of fossil bones representing up to 17 of Lucy's kin from Ethiopia's Afar region - is just one of the many unresolved plot threads in the scientific story about our long-ago ancestors.

"Lucy's Legacy," an exhibition that began its Seattle run last weekend, recaps the story so far. The traveling exhibit made news last year when it came to the Houston Museum of Natural History, because it represented the first time the Ethiopian government allowed Lucy's skeleton to be displayed abroad. Since then, the cultural controversy has settled down - but scientific controversies continue.

From Reuters:

WASHINGTON (Reuters) - A car-sized NASA spacecraft zoomed above the surface of Mercury on Monday, viewing rocky terrain never before seen up close on our solar system's sun-baked innermost planet, scientists said.

The MESSENGER probe flew as low as 124 miles near the equator of Mercury as part of its ongoing exploration of the planet nearest the sun, said project scientist Ralph McNutt of Johns Hopkins University Applied Physics Laboratory.

Initial images sent back to Earth showed newly discovered cliffs on Mercury's surface, with the bulk of the data to be transmitted on Tuesday, McNutt said.

"This is all covering about 30 percent of the planet that has never been seen by a spacecraft before," McNutt said in a telephone interview. "As far as we can tell, everything executed just as it was supposed to."

This was the second of three scheduled encounters before MESSENGER enters into orbit around Mercury in 2011. It flew past Mercury on January 14 and will return in September 2009.

From e! Science News:

The first NASA spacecraft to image and map the dynamic interactions taking place where the hot solar wind slams into the cold expanse of space is ready for launch Oct. 19. The two-year mission will begin from the Kwajalein Atoll, a part of the Marshall Islands in the Pacific Ocean. Called the Interstellar Boundary Explorer or IBEX, the spacecraft will conduct extremely high-altitude orbits above Earth to investigate and capture images of processes taking place at the farthest reaches of the solar system. Known as the interstellar boundary, this region marks where the solar system meets interstellar space.

"The interstellar boundary regions are critical because they shield us from the vast majority of dangerous galactic cosmic rays, which otherwise would penetrate into Earth's orbit and make human spaceflight much more dangerous," said David J. McComas, IBEX principal investigator and senior executive director of the Space Science and Engineering Division at the Southwest Research Institute in San Antonio.

From Air And Space Magazine:

50 indelible images from the first 50 years of spaceflight.

On the occasion of the 50th anniversary of the National Aeronautics and Space Administration, which began its operations on October 1, 1958, we offer this list of the 50 most memorable images from NASA’s history (see all 50 in the photo gallery at right). We recognize that any such ranking is inherently subjective. The rationale for why any one image ranked two slots higher than any other combines several factors, including our attempt to balance the list between human spaceflight, satellite imaging, and planetary exploration. Many wonderful images did not make the final cut—we couldn’t convince the editors to give us 20 pages instead of 10.

The list omits significant events from space history that were not NASA achievements, such as the famous 1958 photograph of Wernher von Braun and the other architects of the Explorer 1 satellite celebrating their success by holding a model of the satellite over their heads, an event that occurred months before NASA existed. Photos from the Apollo moon program predominate, as well they should—it remains the agency’s crowning achievement. We also recognize that, even though the first “A” in NASA stands for “aeronautics,” our list is light on aeronautical breakthroughs (see Moments & Milestones, p. 84). Our only excuse is that the ranking reflects the affinity of the division of space history staff for space topics.

Can Engineers Achieve The Holy Grail Of Energy: Infinite And Clean?

fuel in place. © Eric Verdult/Kennis in Beeld

From Discover Magazine:

All they need to do is tame 200-million-degree plasma—without using too much energy.

For more than half a century, engineers have been trying to build a miniature sun in a bottle: a fusion reactor. Now an international team is embarking on the most intense effort ever to make it happen. If the group succeeds, we could soon generate nearly boundless power from an isotope of hydrogen that is plentiful in our oceans. That’s a big if, though.

In a basic fusion reaction, hydrogen atoms collide, creating helium and releasing energy. Making the reaction work requires heating the atoms to tens or hundreds or millions of degrees Fahrenheit. At these temperatures matter exists only as a plasma, a soup of negatively charged electrons and positively charged atomic nuclei. In a star like our sun, the plasma is held tightly together by gravity. On Earth, a fusion reactor needs a container—and no material is tough enough to withstand direct contact with the plasma.

The fault was probably a poor soldering job on one of the particle collider's 10,000 connections, said Lyn Evans, project leader of the Large Hadron Collider at CERN, the European Nuclear Research Organization.

Only one fault in 10,000 isn't bad, "but it cost dearly," Evans said. It will take at least two months for the repair, meaning the collider cannot be restarted until spring, after its mandatory shutdown due to high electricity costs during the winter.

Evans said he still hasn't been able to examine the damage because the collider is too cold to be opened. The machine operates at extremely cold temperatures to take advantage of superconductivity — the ability of some metals to conduct electricity without any resistance near absolute zero degrees.

No Nobel For You: Top 10 Nobel Snubs

From Scientific America:

As the 2008 laureates are announced, SciAm looks back at some of Nobel history's also-rans.

Every year, the Nobel Foundation in Stockholm, Sweden, announces up to three winners each in the scientific disciplines of chemistry, physics, and physiology or medicine. As of this morning, since 1901, 780 individuals have joined the hallowed ranks of Nobel laureates in these and other categories. And every year, there are murmurings—some louder than others—about the Nobel-worthy scientists who were overlooked. In 1974, when Jocelyn Bell Burnell was left out of the physics prize, her fellow astronomer and Nobel reject, Fred Hoyle, told reporters it was a "scientific scandal of major proportions." Physician-inventor Raymond Damadian famously took out full-page newspaper ads protesting his omission from the 2003 Nobel for MRI technology. This year, some will be asking questions about Robert Gallo, who did not share today's Nobel for medicine or physiology with Luc Montagnier and Francoise Barre-Sinoussi.

Nobel committee proceedings are notoriously shrouded in secrecy, so it's impossible to know all the details behind how each prizewinner is chosen, especially the more recent ones. But, according to Nobel historians, most award exclusions seem to relate to one or more of these criteria: limited slots available (Nobel rules limit the number of recipients to three for each category); ambiguity over who made the crucial contribution; and lack of experience and/or reputation within one's research community.

Scientist: Holographic Television To Become Reality

From CNN:

LONDON, England (CNN) -- Picture this: you're sat down for the Football World Cup final, or a long-awaited sequel to the "Sex and the City" movie and you're watching all the action unfold in 3-D on your coffee table.

It sounds a lot like a wacky dream, but don't be surprised if within our lifetime you find yourself discarding your plasma and LCD sets in exchange for a holographic 3-D television that can put Cristiano Ronaldo in your living room or bring you face-to-face with life-sized versions of your gaming heroes.

The reason for renewed optimism in three-dimensional technology is a breakthrough in rewritable and erasable holographic systems made earlier this year by researchers at the University of Arizona.

Dr Nasser Peyghambarian, chair of photonics and lasers at the university's Optical Sciences department, told CNN that scientists have broken a barrier by making the first updatable three-dimensional displays with memory.

3 Share Nobel Prize For Work On AIDS And Cancer
-- Yahoo News/AP

STOCKHOLM, Sweden - Three European scientists shared the 2008 Nobel Prize in medicine on Monday for separate discoveries of viruses that cause AIDS and cervical cancer, breakthroughs that helped doctors fight the deadly diseases.

French researchers Francoise Barre-Sinoussi and Luc Montagnier were cited for their discovery of human immunodeficiency virus, or HIV, in 1983.

They shared the award with Germany's Harald zur Hausen, who was honored for finding human papilloma viruses that cause cervical cancer, the second most common cancer among women.

U.S. researcher Dr. Robert Gallo was locked in a dispute with Montagnier in the 1980s over the relative importance of their roles in groundbreaking research into HIV and its role in AIDS. Gallo told The Associated Press that he was disappointed at not being included in the prize.

U.S. To Rely On Russia For Manned Spaceflight

From The International Herald Tribune:

STAR CITY, Russia: This place was once no place, a secret military base northeast of Moscow that did not show up on maps. The Soviet Union trained its astronauts here to fight on the highest battlefield of the Cold War: space.

Yet these days, Star City is the place for America's hard-won orbital partnership with Russia, where astronauts train to fly aboard Soyuz spacecraft. And in two years, according to the Bush administration's plans, Star City will be the only place for sending astronauts from any nation to the International Space Station.

The gap is coming: Between 2010, when the National Aeronautics and Space Administration shuts down the space shuttle program, and 2015, when the next generation of U.S. spacecraft is scheduled to arrive, NASA expects to have no human flight capacity and will depend on Russia to get to the $100 billion station, buying seats on Soyuz craft as space tourists do.

As NASA celebrates its 50th anniversary this month, the administration's plan to retire the shuttle and work on a return to the Moon has thrust the U.S. space program squarely into national politics and geopolitical controversy.

The True Costs of Renewable Energy

Beyond the Money: Mark Vargas put solar panels on his home in Santa Clara, Calif., but they get blocked by his neighbor's redwood trees. Earlier this year, Vargas asked prosecutors to press charges against his neighbors for shading the sun. But the couple next door insisted they should not have to chop down the trees to accommodate Vargas' energy demands because they planted the redwoods before he installed the solar panels in 2001.

From Live Science:

As utility costs mount ever higher, Americans now have real options to take home energy matters into their own hands with "green" systems that can pay for themselves in as little as a few years.

Among the choices: wind, solar, geothermal and a "microhydro" option that is potentially cheaper than a year's tuition at many state colleges.

Choosing the do-it-yourself route can offer the freedom of going partially or totally off the grid. And, if the energy generated exceeds your actual usage, you can even sell the excess juice to your utility company. But none of this is free. Here's how much change you should expect to kick in:

Half Of Mammals 'In Decline', Says Extinction 'Red List'
-- Breitbart/AFP

Half the world's mammals are declining in population and more than a third probably face extinction, said an update Monday of the "Red List," the most respected inventory of biodiversity.

A comprehensive survey of mammals included in the annual report by the International Union for Conservation of Nature (IUCN), which covers more than 44,000 animal and plant species, shows that a quarter of the planet's 5,487 known mammals are clearly at risk of disappearing forever.

But the actual situation may be even grimmer because researchers have been unable to classify the threat level for another 836 mammals due to lack of data.

"In reality, the number of threatened mammals could be as high as 36 percent," said IUCN scientist Jan Schipper, lead author of the mammal survey, in remarks published separately in the US-based journal Science.

The most vulnerable groups are primates, our nearest relatives on the evolutionary ladder, and marine mammals, including several species of whales, dolphins and porpoises.

"Our results paint a bleak picture of the global status of mammals worldwide," said Schipper.

From MSNBC:

Infrared and multispectral images reveal 9,000-square-mile structure.

A new remote sensing technology has peeled away layers of mud and rock near Peru's Cahuachi desert to reveal an ancient adobe pyramid, Italian researchers announced on Friday at a satellite imagery conference in Rome.

Nicola Masini and Rosa Lasaponara of Italy's National Research Council (CNR) discovered the pyramid by analyzing images from the satellite Quickbird, which they used to penetrate the Peruvian soil.

The researchers investigated a test area along the river Nazca. Covered by plants and grass, it was about a mile away from Cahuachi's archaeological site, which contains the remains of what is believed to be the world's biggest mud city.

AI Being Put The Test

'Intelligent' Computers Put To The Test' -- The Guardian

Programmers try to fool human interrogators

Can machines think? That was the question posed by the great mathematician Alan Turing. Half a century later six computers are about to converse with human interrogators in an experiment that will attempt to prove that the answer is yes.

In the 'Turing test' a machine seeks to fool judges into believing that it could be human. The test is performed by conducting a text-based conversation on any subject. If the computer's responses are indistinguishable from those of a human, it has passed the Turing test and can be said to be 'thinking'.

No machine has yet passed the test devised by Turing, who helped to crack German military codes during the Second World War. But at 9am next Sunday, six computer programs - 'artificial conversational entities' - will answer questions posed by human volunteers at the University of Reading in a bid to become the first recognised 'thinking' machine. If any program succeeds, it is likely to be hailed as the most significant breakthrough in artificial intelligence since the IBM supercomputer Deep Blue beat world chess champion Garry Kasparov in 1997. It could also raise profound questions about whether a computer has the potential to be 'conscious' - and if humans should have the 'right' to switch it off.

From The Science Blog:

The world’s largest computing grid is ready to tackle mankind’s biggest data challenge from the earth’s most powerful accelerator. Today, three weeks after the first particle beams were injected into the Large Hadron Collider (LHC), the Worldwide LHC Computing Grid combines the power of more than 140 computer centers from 33 countries to analyze and manage more than 15 million gigabytes of LHC data every year.

The United States is a vital partner in the development and operation of the WLCG. Fifteen universities and three U.S. Department of Energy (DOE) national laboratories from 11 states contribute their power to the project.

“The U.S. has been an essential partner in the development of the vast distributed computing system that will allow 7,000 scientists around the world to analyze LHC data, complementing its crucial contributions to the construction of the LHC,” said Glen Crawford of the High Energy Physics program in DOE’s Office of Science. DOE and the National Science Foundation support contributions to the LHC and to the computing and networking infrastructures that are an integral part of the project.

China Sets Sights On First Space Station

From Space Daily:

The success of China's first spacewalk on the Shenzhou 7 mission paves the way for greater things. For China, the next great task will be its first space station. Much reportage has been circulated on this, but ironically, the more we read, the more confused space analysts become. What is China really planning?

It all seemed so simple just a month ago. China would launch a space laboratory on the Shenzhou 8 mission. Despite its name, this would not be a Shenzhou capsule spacecraft, but a new type of vehicle.

This would be followed by the unmanned Shenzhou mission, a conventional Shenzhou, which would dock with it. Finally Shenzhou 10 would carry a crew of three astronauts to the Shenzhou 8-9 complex.

This report seemed reliable for a long time, but this is apparently not the real plan. China has since revealed plans for a small space laboratory module called "Tiangong 1". The name is apparently a reference to a castle or fortress in the sky.

A Future Timeline for Economics

The Futurist:

The accelerating rate of change in many fields of technology all manifest themselves in terms of human development, some of which can be accurately tracked within economic data. Contrary to what the media may peddle and despite periodic setbacks, average human prosperity is rising at a rate faster than any other time in human history. I have described this in great detail in prior articles, and I continue to be amazed at how little attention is devoted to the important subject of accelerating economic growth, even by other futurists.

The time has thus come for making specific predictions about the details of future economic advancement. I hereby present a speculative future timeline of economic events and milestones, which is a sibling article to Economic Growth is Exponential and Accelerating, v2.0.

From Science Daily:

ScienceDaily (Oct. 4, 2008) — After reaching the second-lowest extent ever recorded last month, sea ice in the Arctic has begun to refreeze in the face of autumn temperatures, closing both the Northern Sea Route and the direct route through the Northwest Passage.

This year marked the first time since satellite measurements began in the 1970s that the Northern Sea Route, also known as the Northeast Passage, and the Northwest Passage were both open at the same time for a few weeks.

"NIC analysis of ESA’s Envisat and other satellite datasets indicated that the Northern Sea Route opened when a path through the Vilkitski Strait finally cleared by 5 September," NIC Chief Scientist Dr Pablo Clemente-Colón said via email from aboard the US Coast Guard icebreaker Healy in the Arctic, where he is conducting joint mapping operations with the Canadian Coast Guard.

Big Bang or Big Bounce?: New Theory on the Universe's Birth

(Photo from Windsor Humanist Society)

From American Scientist:

Atoms are now such a commonplace idea that it is hard to remember how radical they used to seem. When scientists first hypothesized atoms centuries ago, they despaired of ever observing anything so small, and many questioned whether the concept of atoms could even be called scientific. Gradually, however, evidence for atoms accumulated and reached a tipping point with Albert Einstein’s 1905 analysis of Brownian motion, the random jittering of dust grains in a fluid.

... Physicists’ understanding of the composition of space and time is following a similar path, but several steps behind. Just as the behavior of materials indicates that they consist of atoms, the behavior of space and time suggests that they, too, have some fine-scale structure—either a mosaic of spacetime “atoms” or some other filigree work.

Material atoms are the smallest indivisible units of chemical compounds; similarly, the putative space atoms are the smallest indivisible units of distance. They are generally thought to be about 10–35 meter in size, far too tiny to be seen by today’s most powerful instruments, which probe distances as short as 10–18 meter. Consequently, many scientists question whether the concept of atomic spacetime can even be called scientific.

The Growth Of Geothermal Power

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.
