Experts Warn Internet Is Running Out of Bandwidth

From FOX News:

Internet users face regular "brownouts" that will freeze their computers as capacity runs out in cyberspace, according to research to be published later this year.

Experts predict that consumer demand, already growing at 60 percent a year, will start to exceed supply as early as 2010 because of more people working online and the soaring popularity of bandwidth-hungry Web sites such as YouTube and services such as the BBC's iPlayer.

How To Wake Up Slumbering Minds

From The Wall Street Journal:

Will the discoveries of neuroscientists help us to think, learn and remember?

We are in the midst of an explosion of knowledge about how the human mind and brain work -- how memory comes in many different types, each stored in a different part of the brain; how our minds constantly process information outside our conscious awareness; how differences in brain function help to define differences in our personalities. A lot of this new knowledge raises provocative questions, not least about human nature.

But as disgruntled students have been saying for ages: How are we ever going to use this stuff? Chemistry can boast of miracle drugs, and genetics has done wonders for our food supply and for medical diagnosis. What about psychology and neuroscience? Shouldn't research on learning and memory and thinking help us to learn, remember and think better?

From Live Science:

To understand the sometimes bold, sometimes nervous governmental reactions to the rapidly growing swine flu crisis, one need only look at the incredibly unpredictable history of horrifically deadly flu pandemics and the frightening outbreaks that did not become pandemics.

Pandemics, plagues and pestilence have beset humans throughout history. But the strategy and response to swine flu unfolding in recent days is rooted in what has been learned from modern flu outbreaks and pandemics going back to the colossal 1918 event.

Sea Ice Spread Linked To Ozone Layer

Image From Watts Up With That?

From The Australian:

SEA ice around Antarctica has been increasing at a rate of 100,000sq km a decade since the 1970s, according to a landmark study to be published today.

The study by the British Antarctic Survey, published in the journal Geophysical Research Letters, says rather than melting as a result of global warming, Antarctica continues to expand.

The fact that Antarctic ice is still growing does not in itself prove that global warming is not happening. But the BAS says increased ice formation can be explained by another environmental concern, the hole in the ozone layer, which is affecting local weather conditions.

10 Deadly Diseases That Hopped Across Species

From Live Science:

Bacteria and viruses that are deadly to one type of creature can evolve quickly to infect another. While the swine flu outbreak is the latest example, a host of infectious and deadly diseases have hopped from animals to humans and from humans to animals.

The cross-species infection can originate on farms or markets, where conditions foster mixing of pathogens, giving them opportunities to swap genes and gear up to kill previously foreign hosts (i.e. you). Or the transfer can occur from such seemingly benign activities as letting a performance monkey on some Indonesian street corner climb on your head. Microbes of two varieties can even gather in your gut, do some viral dancing, and evolve to morph you into a deadly, contagious host.

Hundreds Of Rogue Black Holes May Roam The Milky Way, Swallowing Anything That Gets Too Close

This artist's conception shows a rogue black hole floating near a globular star cluster on the outskirts of the Milky Way.

From Science Daily:

ScienceDaily (Apr. 29, 2009) — It sounds like the plot of a sci-fi movie: rogue black holes roaming our galaxy, threatening to swallow anything that gets too close. In fact, new calculations by Ryan O'Leary and Avi Loeb (Harvard-Smithsonian Center for Astrophysics) suggest that hundreds of massive black holes, left over from the galaxy-building days of the early universe, may wander the Milky Way.

Good news, however: Earth is safe. The closest rogue black hole should reside thousands of light-years away. Astronomers are eager to locate them, though, for the clues they will provide to the formation of the Milky Way.

5 Essential Swine Flu Survival Tips

No kidding! This CDC photograph captured a sneeze in progress, revealing the plume of salivary droplets as they are expelled in a large cone-shaped array from this man's open mouth. The flu virus can spread in this manner and survive long enough on a doorknob or countertop to infect another person. It dramatically illustrating the reason you should cover your mouth when sneezing or coughing to protect others from germ exposure, health officials say.

From Live Science:

Vice President Joe Biden said today to avoid subways and other confined spaces because of the swine flu sweeping the nation.

And yesterday, the first U.S. swine flu death — a toddler — and the decision by health officials to ratchet up their global alert level to just below a full-on pandemic came as a jolt to the system.

Meanwhile, there are a slew of suggestions out there for what you should do. Often the tips don't include enough detail for you to do it right. For example, you probably don't wash your hands effectively or often enough. And did you know you could be infected and spreading the flu up to a full day before you feel symptoms and up to seven days after you get sick?

Russia Mulls Rocket Power 'First'

The future Russian capsule could land on a bright rocket plume

The BBC:

Russia's next-generation manned space vehicle might be equipped with thrusters to perform a precision landing on its return to Earth.

Engineers are considering a rocket-powered landing system for the successor to Russia's Soyuz spacecraft.

If accepted, it would be the first time in history that a manned vehicle relied solely on rocket engines for touchdown.

Previous manned missions have landed on Earth using a parachute or, in the case of space shuttles, a pair of wings.

RKK Energia, Russia's prime developer of manned spacecraft, had to examine the feasibility of the rocket-powered landing as a result of conflicting requirements for the project set by the Russian government.

Have We Found Key To Autism? Scientists Hail 'Monumental' Breakthrough That Could Help Millions

Finding the missing piece: An autistic child during one of his regular behavioral therapy sessions contemplates a jigsaw puzzle

From The Daily Mail:

Scientists have pinpointed rogue genes that could unlock the riddle of autism.

The breakthrough has been hailed as a 'monumental achievement' that could revolutionise understanding and treatment of the condition.

Experts have compared it to the pivotal cancer research of the 1970s, which began unravelling the disease's genetic causes.

Autism and related conditions such as Asperger's syndrome affect at least one in 100 UK children, and some research puts the figure as high as one in 60. Even the lower estimate is ten times the level of 30 years ago.

Is Swine Flu Pandemic Imminent?

PRECAUTIONS Dozens of deaths have occurred from the swine influenza outbreak in Mexico. People wore surgical masks on Monday in Mexico City. Gregory Bull/Associated Press

From Live Science:

The swine flu drama is advancing like wildfire, with the Mexican death count rising steadily, U.S. cases doubling, and the World Health Organization moving a step closer late Monday to declaring the incident a full-on pandemic.

Will this flu become a global pandemic in humans, like AIDS or the "Spanish flu" of 1918–1919 which killed an estimated 50 million people in 18 months?

Declaring a pandemic is a big official deal. It's the more global version of an epidemic, which is a disease outbreak in a specific community or region or population. The word "pandemic" has a specific meaning to doctors and researchers, and once officials apply it to an outbreak, even more money and other resources are rushed to victims. Not to mention that there hasn't been a flu pandemic in more than 40 years (the "Hong Kong flu").

As Swine Flu Spreads, Focus Shifts To A Potential Vaccine

From Discover Magazine:

As the swine flu outbreak continues to spread, with Russia, South Korea, and Australia joining the list of countries with suspected cases and the death toll climbing in Mexico, attention has turned to the potential of a swine flu vaccine that could protect populations from infection. But a new vaccine takes some months to develop. Says Iain Stephenson, an expert on flu vaccines: “We are in a position where if a swine flu virus becomes a pandemic we don’t currently have a vaccine for it…. I think that it is unlikely there will be widespread vaccine in less than six to eight months” [Telegraph]. In the meantime, says Stephenson, patients can be treated with antiviral drugs.

How Hackers Can Steal Secrets From Reflections

Through the eyepiece of Michael Backes’s small Celestron telescope, the 18-point letters on the laptop screen at the end of the hall look nearly as clear as if the notebook computer were on my lap. I do a double take. Not only is the laptop 10 meters (33 feet) down the corridor, it faces away from the telescope. The image that seems so legible is a reflection off a glass teapot on a nearby table. In experiments here at his laboratory at Saarland University in Germany, Backes has discovered that an alarmingly wide range of objects can bounce secrets right off our screens and into an eavesdropper’s camera. Spectacles work just fine, as do coffee cups, plastic bottles, metal jewelry—even, in his most recent work, the eyeballs of the computer user. The mere act of viewing information can give it away.

Presto! Fast Color-Changing Material May Lead To Improved Sunglasses

Photochromic material (Credit: ACS)

From Science Daily:

ScienceDaily (Apr. 28, 2009) — Researchers in Japan are reporting development of a new so-called "photochromic" material that changes color thousands of times faster than conventional materials when exposed to light. The development could lead to a wide range of new products including improved sunglasses, more powerful computers, dynamic holograms, and better medicines, the researchers say.

In the new study, Jiro Abe and colleagues note that photochromic materials are most familiar as the invisible layers found in the lenses of many high-end sunglasses, which change color when exposed to sunlight. For years, researchers have explored the possibility of using these unusual materials for optical data storage in computers and as "molecular switches" for more controlled drug delivery. Conventional photochromic materials, however, tend to be relatively slow-acting (tens of seconds to hours) and unstable, which prevents their use for many advanced applications, the scientists say.

The popular theory that dinosaurs were wiped out by an asteroid 65million years ago has been challenged.

It was believed the Chicxulub crater in Mexico was the 'smoking gun' of the mass extinction event.

Molten droplets from the ancient asteroid impact were found just below the Cretaceous-Tertiary boundary - a geological layer of sediment linked with the extinction.

But soil samples from the 112-mile wide crater show the impact predates the disappearance of the dinosaurs by about 300,000 years.

64 Things Every Geek Should Know

From Lap Top Logic:

If you consider yourself a geek, or aspire to the honor of geekhood, here's an essential checklist of must-have geek skills.

The term 'geek', once used to label a circus freak, has morphed in meaning over the years. What was once an unusual profession transferred into a word indicating social awkwardness. As time has gone on, the word has yet again morphed to indicate a new type of individual: someone who is obsessive over one (or more) particular subjects, whether it be science, photography, electronics, computers, media, or any other field. A geek is one who isn't satisfied knowing only the surface facts, but instead has a visceral desire to learn everything possible about a particular subject.

A techie geek is usually one who knows a little about everything, and is thus the person family and friends turn to whenever they have a question. If you're that type of person and are looking for a few extra skills to pick up, or if you're a newbie aiming to get a handhold on the honor that is geekhood, read on to find out what skills you need to know.

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.

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.

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 neo-X (top) and neo-Y chromosomes of the fruit fly Drosophila miranda, showing how the Y has shrunken slightly through loss of genes. 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.

Why You May Lose That Loving Feeling After Tying The Knot

From Science Daily:

ScienceDaily (Apr. 23, 2009) — Dating couples whose dreams include marriage would do well to step back and reflect upon the type of support they'll need from their partners when they cross the threshold, a new Northwestern University study suggests.

Will the partner who supports your hopes and aspirations while you are dating also help you fulfill important responsibilities and obligations that come with marriage? The answer to that question could make a difference in how satisfied you are after tying the knot.

Getting Real On Wind And Solar

(Asssociated Press/general Electric Via Cleveland Plain Dealer)

From The Washington Post:

Why are we ignoring things we know? We know that the sun doesn't always shine and that the wind doesn't always blow. That means that solar cells and wind energy systems don't always provide electric power. Nevertheless, solar and wind energy seem to have captured the public's support as potentially being the primary or total answer to our electric power needs.

Solar cells and wind turbines are appealing because they are "renewables" with promising implications and because they emit no carbon dioxide during operation, which is certainly a plus. But because both are intermittent electric power generators, they cannot produce electricity "on demand," something that the public requires. We expect the lights to go on when we flip a switch, and we do not expect our computers to shut down as nature dictates.

BREAKING!!!!! Mexico City Closes Schools And Public Events Amid Swine Flu Outbreak: 61 Known Dead, Many Sick -- No Plans To Close U.S./Mexico Border

From Reuters:

MEXICO CITY (Reuters) - A strain of flu never seen before has killed as many as 61 people in Mexico and has spread into the United States, where eight people have been infected but recovered, health officials said on Friday.

Mexico's government said at least 16 people have died of the disease in central Mexico and that it may also have been responsible for 45 other deaths.

The World Health Organization said tests showed the virus in 12 of the Mexican patients had the same genetic structure as a new strain of swine flu, designated H1N1, seen in eight people in California and Texas.

My Comment: When I heard this story today .... two things went through my mind. (1) Is terrorism involved? For Mexico this is a very unique event, they have not suffered serious flu epidemics before .... and rumors have always circulated that Al Qaeda was interested in developing biological weapons for terrorism attacks. Was Mexico targeted because of its proximity to the U.S.?

(2) This epidemic is occurring at the end of the flu season. Like the Great Pandemic of 1918, that influenza outbreak started late spring, quieted down during the summer months, and then hit with a ferocity that killed millions in the Fall and Winter seasons of 1918. Are we in for a repeat?

April 24, 1990: Hubble Becomes Big Eye Above Sky

The Hubble Telescope's wide-field planetary camera took this image in 2007 of the "last hurrah" of a star like our sun. The white dwarf is ending its life by casting off its outer layers of gas, which form a cocoon around the star's remaining core. Blue corresponds to helium, blue-green to oxygen, and red to nitrogen and hydrogen. Ultraviolet light makes the material glow. Image: NASA, ESA, and K. Noll (STScI)

From Wired Science:

1990: The Hubble Space Telescope is launched, beginning a new era of deep space observation that opens up the universe to prying eyes as never before.

NASA's telescope, named for American astronomer Edwin Hubble, was placed into Earth orbit by the space shuttle Discovery. Despite some early teething problems and more recent, well-publicized maintenance issues, Hubble remains a crown jewel in NASA's tiara.

Artificial Intelligence Cracks 4,000-Year-Old Mystery

From Wired News:

An ancient script that's defied generations of archaeologists has yielded some of its secrets to artificially intelligent computers.

Computational analysis of symbols used 4,000 years ago by a long-lost Indus Valley civilization suggests they represent a spoken language. Some frustrated linguists thought the symbols were merely pretty pictures.

"The underlying grammatical structure seems similar to what's found in many languages," said University of Washington computer scientist Rajesh Rao.

'Dark Gulping' Could Explain Black Holes

From Space.com:

No, it's not the next soft-drink campaign. "Dark gulping" is a new hypothesis about how giant black holes might have formed from collapsing dark matter.

Supermassive black holes are a mystery. These behemoths can pack the mass of billions of suns, and often lurk in the centers of big galaxies like the Milky Way. But scientists don't know how they got started nor how they grew so massive.

A new computer model suggests dark gulping is one possible route to forming these monsters. The idea involves invisible dark matter, which is stuff of unknown nature that astronomers know exists because they see its gravitational effects on galaxies.
