The Challenge for Green Energy: How To Store Excess Electricity

From Environment 360:

For years, the stumbling block for making renewable energy practical and dependable has been how to store electricity for days when the sun isn't shining and the wind isn't blowing. But new technologies suggest this goal may finally be within reach.

“Why are we ignoring things we know? We know that the sun doesn’t always shine and that the wind doesn’t always blow.” So wrote former U.S. Energy Secretary James Schlesinger and Robert L. Hirsch last spring in the Washington Post, suggesting that because these key renewables produce power only intermittently, “solar and wind will probably only provide a modest percentage of future U.S. power.”

Memory Test And PET Scans Detect Early Signs Of Alzheimer's

PET scans can detect the decline in glucose metabolism associated with decreased cognitive function, particularly in the temporal and parietal lobes located on the sides and the back of the brain, the regions associated with memory formation and language. UC Berkeley researchers are finding that brain imaging shows promise as a method of detecting early signs of Alzheimer's disease. On the left is a PET scan showing normal levels of glucose metabolism, indicated in yellow and red. The levels of glucose metabolism in the brain are decreased in patients with mild cognitive impairment (middle) and with Alzheimer's disease (right).

From Science Daily:

ScienceDaily (July 15, 2009) — A large study of patients with mild cognitive impairment revealed that results from cognitive tests and brain scans can work as an early warning system for the subsequent development of Alzheimer's disease.

The research found that among 85 participants in the study with mild cognitive impairment, those with low scores on a memory recall test and low glucose metabolism in particular brain regions, as detected through positron emission tomography (PET), had a 15-fold greater risk of developing Alzheimer's disease within two years, compared with the others in the study.

President Obama's Science Czar, John Holdren: Is He An Advocate For Forced Sterializations And Abortions?

President Obama's Science Czar, John Holdren

Obama's Science Czar: Traditional Family Is Obsolete, Punish Large Families -- The Washington Examiner

President Obama's Science Czar, John Holdren, took a controversial and amoral approach to the science of population by recommending mass compulsory sterilization and even forced abortion (and/or forced marriages) under certain circumstances. His 1977 tome, Ecoscience, which he co-authored with Paul and Anne Ehrlich, also displays a revealing disregard for the institution of the traditional human family.

Holdren and the Ehrlichs write:

Radical changes in family structure and relationships are inevitable, whether population control is instituted or not. Inaction, attended by a steady deterioration in living conditions for the poor majority, will bring changes everywhere that no one could consider beneficial. Thus, it is beside the point to object to population-control measures simply on the grounds that they might change the social structure or family relationships.

On Sixth Try, Endeavour Lifts Off -- New York Times

KENNEDY SPACE CENTER, Fla. — For the space shuttle Endeavour, the sixth time proved to be the charm.

After hydrogen leaks, schedule conflicts, lightning strikes and a couple of rain delays, the Endeavour, on the sixth launch attempt, finally lifted to orbit Monday at 6:03 p.m. into the humid Florida sky.

That was one short of NASA’s record for the number of delays. Two previous missions, in 1986 and 1995, were delayed six times before launching on the seventh attempt.

The mission, scheduled to last 16 days, includes five spacewalks dedicated to the construction of the International Space Station. It is the only second time a shuttle mission has been planned for that long.

Tracking The Evolution Of A Pandemic

From The Technology Review:

Understanding how viruses evolve could help predict the next outbreak.

A close examination of the genetic evolution of the three major influenza epidemics of the 20th century concludes that all of the viruses involved evolved slowly, through interspecies genetic exchange, and that genes from the catastrophic 1918 pandemic may have been circulating as many as seven years earlier. If true, this means that widespread genetic surveillance methods should have ample time to detect the next pandemic strain, and possibly even vaccinate against it before it gets out of control.

From Science Daily:

ScienceDaily (July 14, 2009) — The interaction represented produced the famous explanation of the structure of DNA, but the model pictured is a stiff snapshot of idealized DNA. As researchers from Baylor College of Medicine and the University of Houston note in a report that appears online in the journal Nucleic Acids Research, DNA is not a stiff or static. It is dynamic with high energy. It exists naturally in a slightly underwound state and its status changes in waves generated by normal cell functions such as DNA replication, transcription, repair and recombination.

DNA is also accompanied by a cloud of counterions (charged particles that neutralize the genetic material's very negative charge) and, of course, the protein macromolecules that affect DNA activity.

40 Years After Moon Landing: Why Can't We Cure Cancer?

Neil Armstrong took this picture of Buzz Aldrin, showing a reflection in Aldrin's visor of Armstrong and the Lunar Module during the Apollo 11 mission, which landing on the Moon on July 20, 1969. This is one of the few photographs showing Armstrong (who carried the camera most of the time) on the moon. Credit: NASA

From Live Science:

Richard Nixon had every reason to be optimistic when, during his 1971 State of the Union address, he called for a concerted effort to find a cure for cancer. After all, it took only three years for the Manhattan Project to produce the world's first atomic bomb. Nixon's own presidency witnessed the 1969 moon landing, a goal set forth by John F. Kennedy in 1961.

It seemed that given enough resources there was no job that Americans couldn't tackle quickly.

But with $200 billion spent and tens of millions of cancer deaths accumulated since 1971, most would say we are losing the war on cancer. Cancer is the top killer worldwide, responsible for 7.4 million or 13 percent of all deaths annually. In America cancer will soon overtake heart disease as the top killer, claiming more than half million lives annually.

Gravity Wells Could Provide 'Parking Lots' For Spaceships

From McClatchy News:

WASHINGTON — Nature has provided five huge rest stops far out in space for the convenience of spacecraft traveling from Earth.

Some NASA folks call them "parking lots" in space.

They're unusual locations where gravity loses its pull and a spaceship can loiter, rather like a marble at the bottom of a cup, without using a lot of fuel. Three of them are 930,000 miles outside Earth's orbit. One is between the Earth and the sun, and another is hidden on the far side of the sun.

The Spacemen Who Spent Three Months On A Mission To Mars... Without Leaving Moscow

Still smiling: The six volunteers stayed in good spirits during their three-month mission, despite living in quarters just 12ft across

From The Daily Mail:

A crew of six men saw the Sun for the first time in three months today after they were released from a cramped spacecraft simulator.

The volunteers were taking part in a simulated mission to Mars, which was designed to study the psychological and medical aspects of long-duration spaceflight.

They entered voluntary confinement at the end of March when there was still snow on the ground in Moscow.

Longest Insect Migration Revealed

From The BBC:

Every year, millions of dragonflies fly thousands of kilometres across the sea from southern India to Africa.

So says a biologist in the Maldives, who claims to have discovered the longest migration of any insect.

If confirmed, the mass exodus would be the first known insect migration across open ocean water.

It would also dwarf the famous trip taken each year by Monarch butterflies, which fly just half the distance across the Americas.

Biologist Charles Anderson has published details of the mass migration in the Journal of Tropical Ecology.

From Times Online:

El Niño, the warming of the Pacific Ocean that creates chaos in global weather patterns, is on its way back, threatening droughts, floods, crop failure and social unrest.

According to scientists at America’s National Oceanic and Atmospheric Administration (NOAA), a new bout of El Niño is under way as the surface of tropical waters across the eastern Pacific has warmed roughly 1C (1.8F) above normal and is still rising.

Further down, some 150 meters (500ft) below the surface, the waters are heating up — by around 4C (7.2F).

These indications have been emerging for about the past month from satellite pictures and an array of robotic buoys strung out across the Pacific. “The persistently warm sea temperatures are important indicators of an El Niño,” Mike Halpert, of NOAA’s Climate Prediction Centre, said.

From Science Daily:

ScienceDaily (July 14, 2009) — Memories aren't made of actin filaments. But their assembly is crucial for long-term potentiation (LTP), an increase in synapse sensitivity that researchers think helps to lay down memories. In the July 13, 2009 issue of the Journal of Cell Biology, Rex et al. reveal that LTP's actin reorganization occurs in two stages that are controlled by different pathways, a discovery that helps explain why it is easy to encode new memories but hard to hold onto them.

Why Are Human Brains So Big?

Human brains are about three times as large as those of our early australopithecines ancestors that lived 4 million to 2 million years ago, and for years, scientists have wondered how our brains got so big. A new study suggests social competition could be behind the increase in brain size. Credit: NIH, NIDA

From Live Science:

There are many ways to try to explain why human brains today are so big compared to those of early humans, but the major cause may be social competition, new research suggests.

But with several competing ideas, the issue remains a matter of debate.

Compared to almost all other animals, human brains are larger as a percentage of body weight. And since the emergence of the first species in our Homo genus (Homo habilis) about 2 million years ago, the human brain has doubled in size. And when compared to earlier ancestors, such as australopithecines that lived 4 million to 2 million years ago, our brains are three times as large. For years, scientists have wondered what could account for this increase.

Web Site Recreates Apollo 11 Mission In Real Time

Apollo 11

From Yahoo News/AP:

Families crowded around black-and-white television sets in 1969 to watch Neil Armstrong take man's first steps on the moon.

Now, they'll be able to watch the Apollo 11 mission recreated in real time on the Web, follow Twitter feeds of transmissions between Mission Control and the spacecraft, and even get an e-mail alert when the lunar module touches down. Those features are part of a new Web site from the John F. Kennedy Presidential Library and Museum commemorating the moon mission and Kennedy's push to land Americans there first.

"Putting a man on the moon really did unite the globe," said Thomas Putnam, director of the JFK Library. "We hope to use the Internet to do the same thing."

The Web site — WeChooseTheMoon.org — goes live at 8:02 a.m. Thursday, 90 minutes before the 40th anniversary of the Apollo 11 launch from Cape Canaveral, Fla. It will track the capsule's route from the Earth to the Moon, ending with the moon landing and Armstrong's walk — in real time, but 40 years later.

This Is Why the Shuttle Launch Is Delayed

From Popsci.com:

It's hard to launch a Space Shuttle when the launch pad keeps getting struck by lighting. NASA cameras caught 11 lightning strikes, including one direct hit to the pad, near the space shuttle Endeavour's launch pad, during a thunderstorm on July 10.

The storm forced the space agency to call for a 24-hour delay to inspect the shuttle for possible damage. One spectacular strike even hit the top of the launch pad's lightning rod, which channeled the electricity harmlessly away from the shuttle through a series of metal wires.

From The Guardian:

Pictures from a Nasa mission reveal new glimpses of a world as fantastic as any imagined by a science-fiction writer.

Scientists have picked the first crew of Earthlings to fly to another planet. Those chosen for a Mars mission to be launched in October include specimens of thale cress and brewer's yeast, and a microbe known as Conan the Bacterium.

Together with several other microscopic organisms, these representatives of earthly life will be carried in a package that will be flown on a Russian robot spacecraft and are scheduled to be returned to Earth in 2012. The experiment - Living Interplanetary Flight Experiment, or Life - is designed to show if living organisms can survive unprotected in space for long periods and thus support the theory of panspermia, which argues that simple organisms can survive for years as they float through space and that life on Earth could have been wafted here from another world.

Improved dating of such artifacts helped the authors evaluate what contemporary factors might have contributed to the origins of modern human behavior. Top photograph courtesy of Lyn Wadley. Middle photograph courtesy of Richard Roberts. Bottom photograph courtesy of Chris Henshilwood.

From American Scientist:

Two bursts of human innovation in southern Africa during the Middle Stone Age may be linked to population growth and early migration off the continent

In the past decade it has become clear that symbolic expression associated with modern human behavior began in Africa, not Europe. And it occurred tens of thousands of years earlier than was once thought. Answering why is difficult. A first step was more reliable dating of when culturally and technologically advanced people lived during the Middle Stone Age in the south of Africa. Zenobia Jacobs and Richard G. Roberts accomplished that dating, which prompted them to reject climate change as a primary cause for the advancements. Instead, drawing on genetic research, they embrace population growth as a likely, key influence.

New Kind Of Astronomical Object Around Black Hole: Living Fossil Records 'Supermassive' Kick

This artist's conception shows a rogue black hole that has been kicked out from the center of two merging galaxies. The black hole is surrounded by a cluster of stars that were ripped from the galaxies. New calculations by David Merritt, from Rochester Institute of Technology, Jeremy Schnittman, from Johns Hopkins University, and Stefanie Komossa, from the Max-Planck-Institut for Extraterrestrial Physics in Germany suggest that hundreds of massive black holes, left over from the epoch of galaxy formation, are waiting to be detected in the nearby universe. (Credit: Space Telescope Science Institute)

From Science Daily:

ScienceDaily (July 10, 2009) — The tight cluster of stars surrounding a supermassive black hole after it has been violently kicked out of a galaxy represents a new kind of astronomical object and a fossil record of the kick.

A paper published in the July 10 issue of The Astrophysical Journal discusses the theoretical properties of “hypercompact stellar systems” and suggests that hundreds of these faint star clusters might be detected at optical wavelengths in our immediate cosmic environment. Some of these objects may already have been picked up in astronomical surveys, reports David Merritt, from Rochester Institute of Technology, Jeremy Schnittman, from Johns Hopkins University, and Stefanie Komossa, from the Max-Planck-Institut for Extraterrestrial Physics in Germany.

Swearing Makes Pain More Tolerable

From Live Science:

That muttered curse word that reflexively comes out when you stub your toe could actually make it easier to bear the throbbing pain, a new study suggests.

Swearing is a common response to pain, but no previous research has connected the uttering of an expletive to the actual physical experience of pain.

"Swearing has been around for centuries and is an almost universal human linguistic phenomenon," said Richard Stephens of Keele University in England and one of the authors of the new study. "It taps into emotional brain centers and appears to arise in the right brain, whereas most language production occurs in the left cerebral hemisphere of the brain."

The Moon Walkers: Twelve Men Who Have Visited Another World

From The Guardian:

What did it take to become a member of the most exclusive club in human history?

The 12 members of the most exclusive club in human history had many things in common.

All came from a highly technical background and all but one studied aeronautical or astronautical engineering. Growing up, many had been Boy Scouts and even more were active members of their University fraternities. They all went on to study for further degrees – many at military test pilot schools – and almost all of them saw active service in cold war skies, often flying nuclear weapons behind enemy lines.

These high-risk professions often claimed the lives of those to the left and right of them and frequently it was only luck that kept them alive long enough to apply to Nasa.

We might expect such parallel lives in men picked through a selection process devised to seek out "the right stuff". But despite the similarities in their CVs, no two men were from the same mould, as became evident in the years after Apollo.

In 1998, the U.S. Department of Justice (DOJ) brought an antitrust action against Microsoft for a variety of anti-competitive practices in the software industry—chief among them the bundling of the company's Internet Explorer browser into its dominant Windows operating system. The trial revealed plenty of bare-knuckled tactics and market manipulation on behalf of Microsoft, and stained the company's brand for years (perhaps forever, frankly) as a corporate bully. But the central argument from Microsoft was that, with the ascent of the Internet, the browser had become an integral part of the OS, and that competing stand-alone browsers such as Netscape and Opera were moribund products from a transition era. Microsoft contended that it needed to evolve the OS to adapt to the Internet-based era just to stay competitive as a company—a claim that seemed ludicrous back in the '90s, when the software giant seemed to have indomitable market power.

When Galaxies Collide, 280 Million Light Years Away

Stephan's Quintent, Colliding: NASA

From Popsci.com:

A new image using data from NASA's Chandra X-Ray Observatory captures Stephan's Quintet in a new light.

130 years ago, astronomers discovered Stephan's Quintent--a compact group of galaxies 280 million light years from Earth. NASA's Chandra X-ray Observatory has captured the X-rays generated by the interstellar collision, as one of the galaxies is sucked through the center of the group at 2 million miles per hour.

The ridge of blue in the center represent the X-rays emitted by the collision, as shock wave heats the galaxy's gasses.

100 Essential Skills for Geeks

From Geek Dad/Wired:

As Geeks we are expected to have a certain set of skills that the majority of the population does not possess. This list is by no means complete, but I think it is a good sample of the skills required to be a true geek. I won’t pretend to have all the skills listed here. I even had to Google a few of them.

Like all good Geeks you should be able to utilize resources to accomplish any of these things. Knowing where to look for the knowledge is as good as having it so give yourself points if you are certain that you could Google the knowledge necessary for a skill.

U.S. Science Is Tops, But Most Americans Don't Think It Is, A New Survey Finds.

From Scientific American:

Today the American Association for the Advancement of Science (AAAS) and the Pew Research Center released results of a survey examining the attitudes of the general public and the scientific community as they regard to science.

The results, collected from 2,553 AAAS members and 2,001 public respondents, suggest that although average Americans hold a positive view of scientists and support the funding of research, they do not share the same perspectives as the scientific community on a variety of science issues.

trigger an honest reaction from the finder Photo: GETTY

From The Telegraph:

Lost wallets which contain a snapshot of a baby are more likely to be returned to their owners, scientists have discovered.

Researchers left 240 wallets on the streets of Edinburgh last year to see how many were returned to their owners. Some of the wallets contained one of four photographs – the baby, a cute puppy, a family and a portrait of an elderly couple.

Other wallets contained a card suggesting the owner had recently made a charity donation, while a control batch contained no additional items.

Reduced Diet Thwarts Aging, Disease In Monkeys

Rhesus monkeys, left to right, Canto, 27, and on a restricted diet, and Owen, 29, and a control subject on an unrestricted diet, are pictured at the Wisconsin National Primate Research Center at the University of Wisconsin-Madison on May 28, 2009. The two are among the oldest surviving subjects in a pioneering long-term study of the links between diet and aging in Rhesus macaque monkeys, which have an average life span of about 27 years in captivity. Lead researcher Richard Weindruch, a professor of medicine in the UW School of Medicine and Public Health, and co-author Ricki Colman, associate scientist at the Wisconsin National Primate Research Center, report new findings in the journal Science that a nutritious, but reduced-calorie, diet blunts aging and delays the onset of such aged-related disorders as cancer, diabetes, cardiovascular disease and brain atrophy.

From Science Daily:

ScienceDaily (July 10, 2009) — The bottom-line message from a decades-long study of monkeys on a restricted diet is simple: Consuming fewer calories leads to a longer, healthier life.

Writing July 10 in the journal Science, a team of researchers at the University of Wisconsin-Madison, the Wisconsin National Primate Research Center and the William S. Middleton Memorial Veterans Hospital reports that a nutritious but reduced-calorie diet blunts aging and significantly delays the onset of such age-related disorders as cancer, diabetes, cardiovascular disease and brain atrophy.

Birds Fireproof Their Homes

From Live Science:

To beguile females, some males build mansions, others build bowers.

Male great bowerbirds (Chlamydera nuchalis) of northern Australia erect two walls of twigs partially flanking a six-foot-long passageway that they pave with conspicuous bits of bones, stones, shells, and fruits. There, the males strut their stuff, inviting females over for a tryst.

Bower construction takes a week or longer, so it's no fun when brush fire sweeps through the savanna and threatens the males' handiwork.

Yet, as a new study shows, the bowers seem strangely immune to fire.

From New Scientist:

A bout of gawky prototypes have taken to the water for the first time in recent weeks, signalling a new assault on a decades-old problem: how to generate power from the oceans.

While most wind turbines look much the same, the contest to tap that power is more like wacky races than Formula 1. A suite of varied designs are under development in an attempt to work out the most efficient way to generate juice in the harsh chemical and physical environment of the waves and tides.

Fate Of The Potato May Foretell The Future Of Food

From The Detroit News:

A tale from history offers us a prediction about the future of food.

The wonder crop is new and unfamiliar, lauded by scientists and politicians as having the potential to end famine and feed the poor. But the public is skeptical, regarding this new food as unnatural and dangerous. The reaction to genetically modified crops today? In fact, this is what happened when potatoes were introduced into Europe from the Americas in the 1500s and 1600s.

Scientists were enamored with this new foodstuff because it had several valuable properties. Potatoes thrive even in years when the wheat crop has failed, noted a committee of the Royal Society, Britain's pioneering scientific association, in the 1660s. Better still, potatoes can be grown in almost any kind of soil and take only three to four months to mature, against 10 for cereal grains. And potatoes produce two to four times as many calories per acre as wheat, rye or oats. The case for widespread adoption of the potato, the scientists argued, was obvious.

From The Independent:

The astonishing diversity of the Red Planet's landscape is captured by the world's most powerful camera, reports Science Editor Steve Connor.

The most powerful camera that has ever been used to survey another planet is capturing spectacular pictures of the surface of Mars to reveal a rich tapestry of geological features. Located on board the Mars Reconnaissance Orbiter, a Nasa probe launched in 2005, the HiRise camera has already taken detailed images of the outlines of ancient extra-terrestrial seas and rivers – the first unambiguous evidence that shorelines once existed on the Red Planet.

Did an Ancient Volcano Freeze Earth?

From Science Now:

One fine day about 74,000 years ago, a giant volcano on Sumatra blew its top. The volcano, named Toba, may have ejected 1000 times more rock and other material than Mount St. Helens in Washington state did in 1980. In the process, it cooled the climate by at least 10°C, causing a global famine. But could the aftermath have been even worse? A new study puts to rest questions about whether Toba plunged Earth into a 1000-year deep freeze and whether an equivalent event today could jump-start a new, millennia-long ice age.

Giant volcanic eruptions such as Toba briefly cause the opposite of global warming. Although eruptions do emit greenhouse gases such as carbon dioxide, volcanoes also spew sulfur dioxide. Combined with water vapor, sulfur dioxide forms sulfate aerosols, which can spread around the globe, blocking solar radiation and chilling the air before becoming acid rain and snow.

New Kind Of Astronomical Object Around Black Hole: Living Fossil Records 'Supermassive' Kick

Could Michael Jackson Have Been Cloned?

Dolly, right, the first cloned sheep produced through nuclear transfer from differentiated adult sheep cells, and Polly, the world's first transgenic lamb, are in their pen at the Roslin Institute in Edinburgh, Scotland, in early December, 1997. Scientists at the Roslin Institute produced Molly and Polly cloned with a human gene so that their milk will contain a blood clotting protein that can be extracted for use in treating human hemophilia. Ian Wilmut's technique motivated many governments to ban research on human cloning. Dolly was later naturally mated and gave birth to a healthy lamb. (AP Photo/John Chadwick)

From Live Science:

Michael Jackson reportedly was very interested in being cloned.

"I really want to do it Uri, and I don’t care how much it costs," he is said to have told Uri Geller, a self-proclaimed psychic who claims to bend spoons with his mind (boy, if I had that power I'd sure use it for something besides spoon-bending!).

Whether the news report is accurate or not, the fact is the science didn't advance soon enough for Jackson. There have been no substantiated claims of cloned human embryos grown into fetal stages and beyond, despite rumors to the contrary. The capability to so do is near, however.

10 Wind Turbines That Push the Limits of Design

From Popular Mechanics:

The American Wind Energy Association (AWEA) released their 20% Wind Report Card on July 8, following up on a study in which the Department of Energy proposed a goal where 20 percent of U.S. electricity comes from wind energy by 2030. The AWEA gave the overall U.S. push for wind power a “solid B”—high marks from an advocacy group that grades U.S. infrastructure. The highest letter in the report was an A- awarded for “Technology Development.” This is no big surprise—for years now, the government, alternative-energy researchers and entrepreneurs have been putting time and money into making better tech for cleaner, more efficient energy production. Here are 10 wind turbine designs that push the limits of the current design and may help the U.S. get back to being an A student by 2030.
