G.E.’s Breakthrough Can Put 100 DVDs On A Disc

Brian Lawrence leads G.E.’s holographic storage program.
Nathaniel Brooks for The New York Times

From The New York Times:

General Electric says it has achieved a breakthrough in digital storage technology that will allow standard-size discs to hold the equivalent of 100 DVDs.

The storage advance, which G.E. is announcing on Monday, is just a laboratory success at this stage. The new technology must be made to work in products that can be mass-produced at affordable prices.

But optical storage experts and industry analysts who were told of the development said it held the promise of being a big step forward in digital storage with a wide range of potential uses in commercial, scientific and consumer markets.

Mexican Swine Flu Spreads To Europe, Markets Edgy -- Reuters

* First European case confirmed in Spain

* Mexican death toll at 103

* Governments step up health checks at airports

* Stock markets fall, dollar and yen rise

MEXICO CITY, April 27 (Reuters) - Governments around the world acted to stem a possible flu pandemic on Monday, as a virus that has killed 103 people in Mexico and spread to North America was confirmed to have reached Europe.

While the virus has so far killed no one outside Mexico, the fact that it has proved able to spread quickly between humans has raised fears that the world may finally be facing the flu pandemic that scientists say is long overdue.

Looking At Stress—And God—In The Human Brain

Duncan (top) looks at an MRI view of his brain as neuroscientist Adam Gazzaley interprets

From Discover Magazine:

James Brewer takes a seat beside me in a café at the San Diego Convention Center, where we are both attending the largest neuroscience meeting in the world: thirty thousand brains researching brains. With his balding head, bright eyes, and baby cheeks, Brewer, a neurologist at the University of California at San Diego, looks like a large and curious toddler. An unlikely messenger, perhaps, in what for me is now a moment of truth. I had undergone a series of diagnostic procedures in his laboratory, and now, inside the laptop he has placed on the table, are the results of my brain tests.

Ancient Corals May Provide Record of Rapid Sea Level Rise

From Scientific American:

Ancient reefs recently exposed in Mexico show that sea levels can rise by as much as 10 feet in half a century

With Greenland's glaciers melting and on the move while vast ice sheets in Antarctica continue to shatter, the proportion of water in the seas continues to grow. And with the climate at the poles expected to continue to warm rapidly in coming decades, many researchers are trying to determine how much and how quickly sea levels might rise. Now newly excavated reefs in Mexico may have provided an answer: high and fast.

From Science Daily:

ScienceDaily (Apr. 26, 2009) — Two of the most important climate change gases increased last year, according to a preliminary analysis for NOAA’s annual greenhouse gas index, which tracks data from 60 sites around the world.

Researchers measured an additional 16.2 billion tons of carbon dioxide (CO2) — a byproduct of fossil fuel burning — and 12.2 million tons of methane in the atmosphere at the end of December 2008. This increase is despite the global economic downturn, with its decrease in a wide range of activities that depend on fossil fuel use.

Basis For Male Promiscuity Questioned

From Live Science:

Males are promiscuous and females are selective when choosing a mate, biologists have said for decades. But a new study finds it might not be that simple.

The study, published in this month's issue of the journal Trends in Ecology and Evolution, evaluated data on 18 populations – from Pitcairn Islanders to the Dogon of Mali – and found that on average, the variance in the number of children is greater for men than for women. This is about what you'd expect on the basis of long-time theory.

Internet Users 'Could Suffer Brownouts Due To YouTube And iPlayer'

Increased use of video-on-demand websites could hinder the internet's reliability Photo: Bloomberg

From The Telegraph:

Internet users will endure slower and less reliable connections from next year as websites such as YouTube and the BBC's iPlayer cause online traffic to double, experts warn.

Computers will freeze and drop offline with increasing regularity as the web's outdated infrastructure struggles to cope with the surging popularity of bandwidth-hungry video sites, it is claimed.

Analysts are warning that the internet will cease to function as an effective tool of communication – becoming merely an "unreliable toy" for casual users – unless networks are upgraded.

US Declares Public Health Emergency For Swine Flu -- Yahoo News/AP

WASHINGTON – The U.S. is declaring a public health emergency to deal with the emerging new swine flu.

The precautionary step doesn't signal a greater threat to Americans. But it allows the federal and state governments easier access to flu tests and medications.

Homeland Security Secretary Janet Napilotano says roughly 12 million doses of the drug Tamiflu are being released from a federal stockpile so that states can get it if needed.

Wind Power’s Dirty Little Secret

From The Infrastructurist:

There’s a wonderful article in the current issue of Insight, the energy journal published by Platts, called “The Unbearable Lightness of Wind.”

The author, Ross McCracken, tackles the question that nobody has posed yet – what are the economic consequences going to be of putting up all these wind turbines with government subsidies, mandates and “feed-in tariffs” that tell the utilities, “Buy it whatever it costs”?

“The conundrum,” McCracken writes, “lies in the fact that wind does not directly displace fossil fuel generating capacity, but will make this capacity less profitable to maintain.”

Swine Flu Found In Mexican Outbreak -- The Washington Post

An unusual strain of swine flu has been detected among victims of a large outbreak of a severe respiratory illness in Mexico, prompting global health officials, fearful of a potential flu pandemic, to scramble yesterday to try to contain the virus.

At least 1,004 people have been sickened and at least 68 have died, primarily in the sprawling capital of Mexico City, triggering officials to close all schools and universities, museums and libraries and to begin screening air travelers for symptoms before they leave the country.

Officials warned millions of residents to stay home, avoid public places and take other protective measures, such as resisting greeting people with handshakes or kisses. Drugstores reported being inundated with customers seeking face masks, and some subway riders were spotted wearing rubber gloves.

The Geomagnetic Apocalypse — And How to Stop It

From Wired Science:

For scary speculation about the end of civilization in 2012, people usually turn to followers of cryptic Mayan prophecy, not scientists. But that's exactly what a group of NASA-assembled researchers described in a chilling report issued earlier this year on the destructive potential of solar storms.

Entitled "Severe Space Weather Events — Understanding Societal and Economic Impacts," it describes the consequences of solar flares unleashing waves of energy that could disrupt Earth's magnetic field, overwhelming high-voltage transformers with vast electrical currents and short-circuiting energy grids. Such a catastrophe would cost the United States "$1 trillion to $2 trillion in the first year," concluded the panel, and "full recovery could take four to 10 years." That would, of course, be just a fraction of global damages.

Antarctica’s Bipolar Disorder

From Watts Up With That?

Two days ago I questioned how Antarctic ice could be both “melting faster than expected” and “expanding” at the same time. Yet (as WUWT has noted before) the answer is obvious - according to NASA, most of Antarctica is both cooling rapidly and heating rapidly at the same time.

Since nearly the entire continent is both cooling and heating simultaneously, it makes perfect sense (using AGW logic) that the ice would be rapidly expanding and rapidly retreating simultaneously. In 2004, NASA thought that Antarctica was cooling by as much as 15 degrees C per century. But after three more years of cooling, they changed the map to show a warming trend in 2007.

The Story Of X: Evolution Of A Sex Chromosome

The X has remained about the same size as the fly's other chromosomes, though its genes are in the process of adapting to the Y's degeneration. (Credit: Doris Bachtrog/UC Berkeley)

From Science Daily:

In the first evolutionary study of the chromosome associated with being female, University of California, Berkeley, biologist Doris Bachtrog and her colleagues show that the history of the X chromosome is every bit as interesting as the much-studied, male-determining Y chromosome, and offers important clues to the origins and benefits of sexual reproduction.

"Contrary to the traditional view of being a passive player, the X chromosome has a very active role in the evolutionary process of sex chromosome differentiation," said Bachtrog, an assistant professor of integrative biology and a member of UC Berkeley's Center for Theoretical Evolutionary Genomics.

Nicotine Takes Edge Off Anger

From Live Science:

Smoking to relieve stress is nothing new, but now a brain imaging study shows just how nicotine can blunt our anger response.

People who received half a nicotine patch dose proved less likely to rise to provocation, compared to when they took a placebo. This may support the idea that angry or stressed-out individuals can more easily become addicted to cigarettes, researchers say.

"The findings suggest that people in anger provoking situations may be more susceptible to the effects of nicotine," said Jean Gehricke, a psychiatry researcher at the University of California in Irvine.

This also represents the first study to identify a brain system that is most reactive to nicotine and has the strongest connection with anger response, Gehricke told LiveScience.

Could Food Shortages Bring Down Civilization?

From Scientific American:

The biggest threat to global stability is the potential for food crises in poor countries to cause government collapse

One of the toughest things for people to do is to anticipate sudden change. Typically we project the future by extrapolating from trends in the past. Much of the time this approach works well. But sometimes it fails spectacularly, and people are simply blindsided by events such as today’s economic crisis.

2009 Space Oddity: 'Blob' 12.9Billion Light Years Away Baffles Astronomers

Unknown entity: The size and substance of the Lyman-alpha
blob 'Himiko' are a mystery to astronomers.

From The Daily Mail:

You'd think that astronomers would have a more scientific term for such a discovery, but the 'blob' in this image is so far away that its contents remain a mystery.

One of the most distant objects in our universe, the blob is 12.9billion light years away, and 55,000 light years wide, making it nearly ten times the mass of galaxies of a similar age.

The Lyman-alpha blob, named 'Himiko', after an ancient Japanese queen, is believed to have been formed when the universe was relatively young.

World First For Strange Molecule

From The BBC:

A molecule that until now existed only in theory has finally been made.

Known as a Rydberg molecule, it is formed through an elusive and extremely weak chemical bond between two atoms.

The new type of bonding, reported in Nature, occurs because one of the two atoms in the molecule has an electron very far from its nucleus or centre.

It reinforces fundamental quantum theories, developed by Nobel prize-winning physicist Enrico Fermi, about how electrons behave and interact.

Who Discovered The North Pole?

Frederick Cook and Robert Peary both claimed they discovered the North Pole. AGIP / Rue des Archives / The Granger Collection, New York

From The Smithsonian:

A century ago, explorer Robert Peary earned fame for discovering the North Pole, but did Frederick Cook get there first?

On September 7, 1909, readers of the New York Times awakened to a stunning front-page headline: "Peary Discovers the North Pole After Eight Trials in 23 Years." The North Pole was one of the last remaining laurels of earthly exploration, a prize for which countless explorers from many nations had suffered and died for 300 years. And here was the American explorer Robert E. Peary sending word from Indian Harbour, Labrador, that he had reached the pole in April 1909, one hundred years ago this month. The Times story alone would have been astounding. But it wasn't alone.
