Google CEO Sees Future For News In Advertising

From The Globe And Mail:

SAN DIEGO — Google's CEO Eric Schmidt recommends that news organizations continue to rely on advertising but seek new ways to reach readers.

Without providing specific recipes, Mr. Schmidt's speech Tuesday lays out a few possibilities.

One is a site for medicine similar to the online encyclopedia Wikipedia, which lets users collectively contribute and edit entries.

He says there's still room for subscription and pay-by-the-piece journalism but he emphasizes advertising, the source of 98 per cent of Google Inc.'s revenue.

Oldest Stone Blades Uncovered

Science Now:

CHICAGO, ILLINOIS--Paleoanthropologists working in Africa have discovered stone blades more than a half-million years old. That pushes the date of the earliest known blades back a remarkable 150,000 years and raises a question: What human ancestor made them?

Not long ago, researchers thought that blades were so hard to make that they had to be the handiwork of modern humans, who had evolved the mental wherewithal to systematically strike a cobble in the right way to produce blades and not just crude stone flakes. First, they were thought to be a hallmark of the late Stone Age, which began 40,000 years ago. Later, blades were thought to have emerged in the Middle Stone Age, which began about 200,000 years ago when modern humans arose in Africa and invented a new industry of more sophisticated stone tools. But this view has been challenged in recent years as researchers discovered blades that dated to 380,000 years in the Middle East and to almost 300,000 years ago in Europe, where Neandertals may have made them (ScienceNOW, 1 December 2008).

Sleep: Spring Cleaning For The Brain?

On the left, the brain of the well-rested blue fly has low levels of a synaptic protein called BRP in this 3D view from a confocal mircoscope. On the right, the brain of the sleep-deprived fly glows orange in areas of BRP concentration. (Bruchpilot or BRP is a protein involved in communication between neurons.)In the tired fly, the protein is present at high concentartions in three major areas of the fly's brain that are associated with learning. Sleep reduces the levels of this protein, an indication that synapses get smaller and/or weaker. This process of "downscaling" may be important so the brain is reset to normal levels of synaptic activity and can begin learning again the next day. (Credit: Courtesy of UW Health Public Affairs)

From Science Daily:

ScienceDaily (Apr. 11, 2009) — If you've ever been sleep-deprived, you know the feeling that your brain is full of wool.

Now, a study published in the April 3 edition of the journal Science has molecular and structural evidence of that woolly feeling — proteins that build up in the brains of sleep-deprived fruit flies and drop to lower levels in the brains of the well-rested. The proteins are located in the synapses, those specialized parts of neurons that allow brain cells to communicate with other neurons.

Great Golfers' Brains Have More Gray Matter

From Live Science:

As Tiger Woods goes for his fifth green jacket in this weekend's Masters Tournament, mortal golfers wonder what's inside his head that keeps him winning. Well, chances are his brain actually has more gray matter than the average weekend duffer.

Researchers at the University of Zurich have found that expert golfers have a higher volume of the gray-colored, closely packed neuron cell bodies that are known to be involved with muscle control. The good news is that, like Tiger, golfers who start young and commit to years of practice can also grow their brains while their handicaps shrink.

From FOX News:

The U.S. and major foreign partners on the International Space Station have agreed in principle to keep it operating through 2020, at least five years beyond the current deadline, according to government and industry officials.

There had been looming questions about the future of the space station — which took nearly two decades and more than $100 billion to design and build — because until now, the major partners hadn't committed to keeping it going past 2015.

An extension could give new momentum to the scientific research conducted there, which initially was delayed by false starts and problems finishing assembly of the station.

Wind Turbine Imports Increase; Can U.S. Factories Catch Up?

From McClatchy News:

WASHINGTON — Manufacturing of wind turbine parts in the United States grew last year as the market for wind energy boomed, but trade figures show that imports continued at a high rate after years of big growth.

Wind turbine imports from Europe and Asia rose from $60 million in 2004 to $2.5 billion in 2008, according to Customs data reviewed by McClatchy. Imports of other equipment usually, but not always, used for wind power production also increased in the same period. The value of AC generators and towers, for instance, jumped from $84 million to $1.6 billion.

The numbers suggest that there's potential for U.S. manufacturers to seize some opportunities, and some of the largest turbine makers say they're looking for U.S. suppliers.

Study: Biofuel Threatens Water Supplies

From Live Science:

The production of bioethanol may use up to three times as much water as previously thought, a new study finds, becoming the latest work that could burst the biofuel bubble.

A gallon of ethanol may require up to more than 2,100 gallons of water from farm to fuel pump, depending on the regional irrigation practice in growing corn, according to the study detailed in the April 15 issue of journal Environmental Science & Technology.

But the water usage isn't quite so high everywhere: A dozen states in the Corn Belt consume less than 100 gallons of water per gallon of ethanol, making them better suited for ethanol production, the study found.

Printed Supercapacitor Could Feed Power-Hungry Gadgets

From New Scientist:

A supercapacitor – a device that can unleash large amounts of charge very quickly – has been created using printing technology for the first time. The advance will pave the way for "printed" power supplies that could be useful as gadgets become thinner, lighter and even flexible.

Advances in electronics mean portable gadgets are shrinking in size but growing in their energy demands, and conventional batteries are struggling to cope.

Batteries are slow to recharge because they store energy chemically. By contrast, capacitors, which are common in electronics, are short-term stores of electrical energy that charge almost instantaneously but hold little energy.

From Nature News:

Climate change takes the blame for many dim future prospects: rising sea levels, more frequent droughts and disappearing glaciers, to name just a few. But perhaps the warming trend should be absolved of responsibility for a predicted bump in the global burden of infectious disease.

That's the bottom line of a paper in the April issue of the journal Ecology, which argues that the geographical ranges of infectious diseases are more likely to shift than to expand (K. D. Lafferty Ecology 90, 888–900; 2009). "You often see a list of the 12 terrible things that are going to happen with climate change, and increases in infectious diseases is often on that list," says Kevin Lafferty, an ecologist with the US Geological Survey in Santa Barbara, California. But data from diseases such as yellow fever and malaria, he says, provide "a different reality".

Research Could Lead To New Non-antibiotic Drugs To Counter Hospital Infections

When worms (Caenorhabditis elegans) ate the bacteria Pseudomonas aeruginosa that were raised on low levels of phosphates, unexpected large red spots appeared in their intestinal tracts. The worms then died, so researchers dubbed the condition "Red Death." They theorized that providing P. aeruginosa with phosphate would protect weakened or immunosuppressed hospital patients from this lethal pathogen. (Credit: John Alverdy, University of Chicago Medical Center)

From Science Daily:

ScienceDaily (Apr. 9, 2009) — Lack of an adequate amount of the mineral phosphate can turn a common bacterium into a killer, according to research to be published in the April 14, 2009, issue of the Proceedings of the National Academies of Science. The findings could lead to new drugs that would disarm the increasingly antibiotic-resistant pathogen rather than attempting to kill it.

Pseudomonas aeruginosa is one of the most serious hospital-acquired pathogens. A common cause of lung infections, it is also found in the intestinal tract of 20 percent of all Americans and 50 percent of hospitalized patients in the United States.

Losing It: Why Self-Control Is Not Natural

From Live Science:

After dinner last night, I lost my usual self-control and ate half a box of cookies. No wonder. My self-control had been under pressure all day. I righteously refused a muffin at breakfast, didn’t scream at my kid to get out the door although we were late, made a conscious decision not to run over a pedestrian crossing against the light, kept my fist from pounding on the table during a faculty meeting, and resisted the urge to throw an annoying student out of my office.

But by 7 p.m., my self-control mechanism was worn out, and down those cookies went.

The empty box would have been no surprise to Yale University psychologist Joshua Ackerman and colleagues who have discovered that self-control not only wears us down, even thinking about other people's self-control is too much to handle.

Standing Watch Over A Crowded Space

From The BBC:

On 10 February this year, a defunct Russian communications satellite crashed into an American commercial spacecraft, generating thousands of pieces of orbiting debris.

At the time, some observers put the odds of such an event occurring at millions, maybe billions, to one.

But experts had been warning for years that useable space was becoming crowded, boosting the possibility of a serious collision.

They have argued both for better monitoring of the space environment and for policies aimed at controlling the production of debris.

Over the past two years, a number of incidents have drawn attention to the problem of space debris.

From Science Daily:

ScienceDaily (Apr. 10, 2009) — Two places on opposite sides of Earth may hold the secret to how the moon was born. NASA's twin Solar Terrestrial Relations Observatory (STEREO) spacecraft are about to enter these zones, known as the L4 and L5 Lagrangian points, each centered about 93 million miles away along Earth's orbit.

As rare as free parking in New York City, L4 and L5 are among the special points in our solar system around which spacecraft and other objects can loiter. They are where the gravitational pull of a nearby planet or the sun balances the forces from the object's orbital motion. Such points closer to Earth are sometimes used as spaceship "parking lots", like the L1 point a million miles away in the direction of the sun. They are officially called Libration points or Lagrangian points after Joseph-Louis Lagrange, an Italian-French mathematician who helped discover them.

When Life As We Know It Became Possible On Earth

From The Independent:

The mystery of how our planet's atmosphere became rich in oxygen has finally been solved.

It was one of the most important changes to have happened to the Earth's atmosphere and it was the reason why today we can breathe life-giving oxygen. And yet the Great Oxidation Event has remained a mystery – until now.

Without oxygen, life on Earth would not exist as we know it. It has provided the supercharged air that has fuelled an explosion in the diversity and size of all living organisms, from the smallest shrimp to the biggest dinosaur.

From New Scientist:

What similarities will alien life forms have to living things here on Earth? We won't know until we find some, but now there is evidence that at least the basic building blocks will be the same.

All terrestrial life forms share the same 20 amino acids. Biochemists have managed to synthesise 10 of them in experiments that simulate lifeless prebiotic environments, using proxies for lightning, ionising radiation from space, or hydrothermal vents to provide the necessary energy. Amino acids are also found inside meteorites formed before Earth was born.

Paul Higgs and Ralph Pudritz at McMaster University in Hamilton, Ontario, Canada, point out that all these experiments produced a subset of the same 10 amino acids and calculate that these 10 require the least amount of energy to form.

This, they argue, suggests that if alien life exists it probably has the same 10 amino acids at its core.

From Science Daily:

ScienceDaily (Apr. 9, 2009) — The Earth's original atmosphere held very little oxygen. This began to change around 2.4 billion years ago when oxygen levels increased dramatically during what scientists call the "Great Oxidation Event." The cause of this event has puzzled scientists, but researchers writing in Nature have found indications in ancient sedimentary rocks that it may have been linked to a drop in the level of dissolved nickel in seawater.

"The Great Oxidation Event is what irreversibly changed surface environments on Earth and ultimately made advanced life possible," says research team member Dominic Papineau of the Carnegie Institution's Geophysical Laboratory. "It was a major turning point in the evolution of our planet, and we are getting closer to understanding how it occurred."

Efficient Power At Any Wind Speed

Vail Resorts said Tuesday that it would buy credits for wind power like that generated by the turbines at the Gray County Wind Farm in Kansas. Orlin Wagner/Associated Press

From Scientific American:

One of wind power’s drawbacks is its variability: sometimes the breeze is weak; other times it is strong. To convert the rotation of wind turbines into electricity efficiently, however, generators require a single turning speed. Faster or slower than this “sweet spot” and efficiency falls off fast. To compensate, engineers design turbine hardware to have adjustable blade angles to shed surplus wind energy or to capture more. Wind turbines often also employ a transmission to gear the shaft speed up or down to the sweet spot. But both mechanisms add weight, complexity and cost.

ExRo Technologies in Vancouver is commercializing what should be a better idea: a generator that operates efficiently over a wide speed range. Retrofitted wind turbines could produce as much as 50 percent more power over time, CEO John McDonald states.

New Way To Split Water Into Hydrogen And Oxygen Developed

From Science Daily:

ScienceDaily (Apr. 8, 2009) — The design of efficient systems for splitting water into hydrogen and oxygen, driven by sunlight is among the most important challenges facing science today, underpinning the long term potential of hydrogen as a clean, sustainable fuel. But man-made systems that exist today are very inefficient and often require additional use of sacrificial chemical agents. In this context, it is important to establish new mechanisms by which water splitting can take place.

Now, a unique approach developed by Prof. David Milstein and colleagues of the Weizmann Institute’s Organic Chemistry Department, provides important steps in overcoming this challenge. During this work, the team demonstrated a new mode of bond generation between oxygen atoms and even defined the mechanism by which it takes place. In fact, it is the generation of oxygen gas by the formation of a bond between two oxygen atoms originating from water molecules that proves to be the bottleneck in the water splitting process. Their results have recently been published in Science.

From Science Daily:

ScienceDaily (Apr. 7, 2009) — In a step toward using gas hydrates as a future energy source, researchers in New York are reporting the first identification of an optimal temperature and pressure range for maximizing production of natural gas from the icy hydrate material.

Marco Castaldi, Yue Zhou, and Tuncel Yegualp note that gas hydrates, also known as "ice that burns," are a frozen form of natural gas (methane). This material exists in vast deposits beneath the ocean floor and Arctic permafrost in the United States and other areas. Scientists believe that fuel from these frozen chunks, formed at cold temperatures and high pressures, may help fuel cars, heat homes, and power factories in the future. Although scientists have identified several different methods for extracting the fuel, including depressurization, researchers have not found an practical approach for producing the gas on an industrial scale.

Mt. Redoubt March 26, 2009

From Watts Up With That:

Starting on March 22, a series of major eruptions have taken place from Mt. Redoubt in Alaska. The biggest exceeded 65,000 feet in height. More than a dozen eruptions as high as 60,000 have followed the first week alone. Activity may continue for weeks or months based on the volcano’s history.

Climatologists may disagree on how much the recent global warming is natural or manmade but there is general agreement that volcanism constitutes a wildcard in climate, producing significant global scale cooling for at least a few years following a major eruption. However, there are some interesting seasonal and regional variations of the effects.

From Science Daily:

ScienceDaily (Apr. 6, 2009) — Saturn's largest moon, Titan, may have a subterranean ocean of hydrocarbons and some topsy-turvy topography in which the summits of its mountains lie lower than its average surface elevation, according to new research.

Titan is also more squashed in its overall shape—like a rubber ball pressed down by a foot—than researchers had expected, said Howard Zebker, a Stanford geophysicist and electrical engineer involved in the work. The new findings may help explain the presence of large lakes of hydrocarbons at both of Titan's poles, which have been puzzling researchers since being discovered in 2007.

From New Scientist:

IS POKER a game of skill or luck? For regular players that's a no-brainer, but showing that skill wins out has proven surprisingly difficult for mathematicians. Now two studies that tapped the vast amounts of data available from online casinos have provided some of the best evidence yet that poker is skill-based. Many hope that the results will help to roll back laws and court decisions that consider poker gambling, and therefore illegal in certain contexts.

'I Predicted Killer Quake, But Officials Accused Me Of Scaremongering': Says Italian Seismologist

Seismologist Giacchino Giuliani predicted the earthquake which killed up to 100 people in L'Aquila just weeks before it struck

From The Daily Mail:

The Italian scientist who predicted a major earthquake which killed 90 people just weeks before disaster struck said authorities refused to take his claim seriously.

Seismologist Giacchino Giuliani said he was reported to authorities for spreading panic after the government claimed his research had no scientific foundation.

The 6.3-magnitude quake struck at around 2.30am UK time near L'Aquila.

The first tremors in the region were felt in mid-January and continued at regular intervals, creating mounting alarm in the medieval city, 60 miles east of Rome.
