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?

Spacecraft Reveals Stunning New Views of Mercury

The features this image from MESSENGER's Oct. 6, 2008 flyby shows never-before seen terrain. 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. Other neighboring impact craters, such as in the upper left of this image, appear to be filled with smooth plains material. Credit: NASA/JHUAPL/CIW. (Photo from Live Science)

From Live Science:

A NASA probe has begun beaming back stunning new images from its successful second flyby of Mercury, the planet closest to the sun.

NASA's MESSENGER probe captured never-before-seen views of the Mercury during its encounter on Monday. The spacecraft zipped past Mercury for the second time this year and used the planet's gravity to adjust its path as it continues en route to become the first probe to orbit the planet in March 2011.

One new image shows large patterns of ray-like lines extending southward across much of the planet surface from a young, newly-imaged crater. The previously-imaged Kuiper crater and others craters also have similar webs of lines radiating outward.

One Bad Weld Shuts Down A Billion Dollar Science project

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".

From The National Geographic:

Some fake drugs are better than others, armadillos are assaulting our history, and slime mold is smarter than we think—these and other offbeat scientific triumphs were honored Thursday night at the 2008 Ig Nobel Prize ceremony.

The prizes celebrate "achievements that first make people laugh, and then make them think."

More than 1,200 people attended a raucous affair at Harvard University, dubbed the "18th First Annual Ig Nobel Prize Ceremony" in honor of this year's theme—redundancy.

William Lipscomb, who had won the Nobel Prize in chemistry in 1976, dispensed prizes to the ten honorees. He himself was the prize in the Win a Date With a Nobel Laureate contest.

The gala is thrown every year by the science/humor journal Annals of Improbable Research (AIR).

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.
