In Search Of Lithium: The Battle For The 3rd Element

The US Geological Survey claims at least 4.5 million tones of lithium could be extracted in Salar De Uyuni, while another report puts it as high as nine million tons

From The Daily Mail:

The good news: A wonder metal that fires your phone, iPod and shiny new electric car is so clean it may save the planet. The bad news: More than half of the world's lithium is beneath this Bolivian desert...and getting it is so dirty it inspired the latest Bond plot

Darkness falls across the Andes, turning the distant snow caps from blinding white to nothingness in the blink of an eye. From the east, the night races across the bleak Altiplano towards us, as the temperature plummets to below zero, leaving the windswept emptiness of the planet's largest salt plain in a vast cold shadow.

Mt. Redoubt Eruptions – What Effect If Any On The Summer? Winter?

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.

'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.

From Philadelphia Inquirer:

Thirty years ago, the nuclear energy industry in the United States seemed all but headed for the scrapyard. Now it's poised for a rebirth.

The impetus is climate change. Nuclear power is touted as the one major electricity source that's emission-free and reliable, able to generate massive amounts of power night and day, in wind and calm.

But hovering over nuclear's new dawn is an incident that began at 4 a.m. on March 28, 1979.

Deep within Reactor 2 at the Three Mile Island nuclear power plant along the Susquehanna River near Harrisburg, main water pumps failed.

At the end of a cascade of disasters, the reactor core melted down, though the containment walls were not breached.

The accident and other factors set the industry reeling. Costs rose. Plants were canceled.

From Science Daily:

ScienceDaily (Apr. 4, 2009) — Researchers have developed a critical part of a hydrogen storage system for cars that makes it possible to fill up a vehicle's fuel tank within five minutes with enough hydrogen to drive 300 miles.

The system uses a fine powder called metal hydride to absorb hydrogen gas. The researchers have created the system's heat exchanger, which circulates coolant through tubes and uses fins to remove heat generated as the hydrogen is absorbed by the powder.

The heat exchanger is critical because the system stops absorbing hydrogen effectively if it overheats, said Issam Mudawar, a professor of mechanical engineering who is leading the research.

How Baseball Players Catch Fly Balls

From Live Science:

With the crack of the bat, you see the ball jump into the air. You take a few quick steps forward. Then, as you watch the ball continue to rise faster, you feel your stomach sink knowing that this one is going over your head. What went wrong?

How our eyes, brains, arms and legs combine to track and catch a fly ball has stumped scientists for more than 40 years.

A new study supports the original theory of it all while offering some practical tips.

By watching fielders shag pop flies, researchers have noticed a few interesting quirks. First, great ballplayers will not sprint to the exact spot on the field where they think the ball will land and then wait for it. Rather, they usually adjust their speed to arrive at the landing spot just as the ball arrives.

Gamma-Ray Burst Caused Mass Extinction?

Gamma-ray bursts are thought to be streams of high-energy radiation produced when the core of a very massive star collapses, as seen in the above artist's rendering. An April 2009 paper suggests that a gamma-ray burst aimed at Earth may have caused a mass extinction event 440 million years ago, and that a similar celestial catastrophe could happen again.

From National Geographic:

A brilliant burst of gamma rays may have caused a mass extinction event on Earth 440 million years ago—and a similar celestial catastrophe could happen again, according to a new study.

Most gamma-ray bursts are thought to be streams of high-energy radiation produced when the core of a very massive star collapses.

The new computer model shows that a gamma-ray burst aimed at Earth could deplete the ozone layer, cause acid rain, and initiate a round of global cooling from as far as 6,500 light-years away.

'Eureka Machine' Puts Scientists In The Shade By Working Out Laws Of Nature

From The Gaurdian:

The machine, which took only a few hours to come up with Newton's laws of motion, marks a turning point in the way science is done

Scientists have created a "Eureka machine" that can work out the laws of nature by observing the world around it – a development that could dramatically speed up the discovery of new scientific truths.

The machine took only hours to come up with the basic laws of motion, a task that occupied Sir Isaac Newton for years after he was inspired by an apple falling from a tree.

Scientists at Cornell University in New York have already pointed the machine at baffling problems in biology and plan to use it to tackle questions in cosmology and social behaviour.

Wind Turbines Could More Than Meet U.S. Electricity Needs, Report Says

From The L.A. Times:

The Interior Department report, which looks at the potential of wind turbines off the U.S. coast, is part of the government's process to chart a course for offshore energy development.

Reporting from Arlington, Va. -- Wind turbines off U.S. coastlines could potentially supply more than enough electricity to meet the nation's current demand, the Interior Department reported Thursday.

Simply harnessing the wind in relatively shallow waters -- the most accessible and technically feasible sites for offshore turbines -- could produce at least 20% of the power demand for most coastal states, Interior Secretary Ken Salazar said, unveiling a report by the Minerals Management Service that details the potential for oil, gas and renewable development on the outer continental shelf.

From Science News:

Researchers identify key protein that reactivates virus under stress.

A single viral protein enables dormant herpes virus to wake up, suggests a study appearing online March 26 in PLoS Pathogens. The protein, called VP16, acts as the gatekeeper for the damaging, infective activity of the virus, new results in mice show.

Figuring out what causes an inactive, latent state to become a highly infectious state is “very, very important for understanding this virus,” says study coauthor Nancy Sawtell of Cincinnati Children’s Hospital Medical Center in Ohio. The results may lead to a better way to control herpes simplex virus type 1, a virus carried by more than 70 percent of the human population, Sawtell says.

Sleep May Help Clear Brain For New Learning

Washington University scientists used genetically modified fruit flies to track the creation of new brain synapses, junctures where two brain cells communicate. They found that two scenarios that give the fruit fly's brain a workout caused new synapses to arise. To their surprise, all of the new synapses originated from a group of 16 cells in the fly brain's internal timekeeping mechanism. The cells are highlighted in the encircled area above.

From Science Daily:

ScienceDaily (Apr. 3, 2009) — A new theory about sleep's benefits for the brain gets a boost from fruit flies in the journal Science. Researchers at Washington University School of Medicine in St. Louis found evidence that sleep, already recognized as a promoter of long-term memories, also helps clear room in the brain for new learning.

The critical question: How many synapses, or junctures where nerve cells communicate with each other, are modified by sleep? Neurologists believe creation of new synapses is one key way the brain encodes memories and learning, but this cannot continue unabated and may be where sleep comes in.

Slurping up cold streams of star fuel, some of the Universe's first galaxies got fat quickly, new observations suggest. The findings could overturn existing models for the formation and evolution of galaxies that predict their slow and steady growth through mergers.

Researchers using the Subaru telescope in Hawaii have identified five distant galaxy clusters that formed five billion years after the Big Bang. They calculated the mass of the biggest galaxy in each of the clusters and found, to their surprise, that the ancient galaxies were roughly as big as the biggest galaxies in equivalent clusters in today's Universe.

From Science Daily:

ScienceDaily (Mar. 31, 2009) — Research by Michigan State University scientists is helping shed light on neutron stars, city-sized globs of ultra-dense matter that occasionally collapse into black holes.

A team led by Betty Tsang, a professor at MSU’s National Superconducting Cyclotron Laboratory, has had some success in measuring a key nuclear quality that may make it easier to describe the outer crusts of such stars.

Humans Losing Touch With Nature

From Live Science:

With so much of life based on electronic representations of reality, humans risk losing touch with nature, says University of Washington psychologist Peter Kahn.

From web cams that offer views of wildlife to virtual tours of the Grand Canyon to robotic pets, modern technology increasingly is encroaching into human connections with the natural world. Kahn and his colleagues believe this intrusion may emerge as one of the central psychological problems of our times.

Sounds Good: The Flat Loudspeaker That Is As Thin As A Sheet Of Foil

The speaker is so thin it resembles a sheet of tin foil

From The Daily Mail:

A groundbreaking new loudspeaker that can be printed on and used as a wall poster has been developed by British engineers.

The lightweight and flexible speakers are less than 0.25mm thick and could also be concealed in car interiors or ceiling tiles.

They were developed by the University of Warwick spin-out company, Warwick Audio Technologies, who plan to start selling them later this year.

Giza Pyramids Align Toward City of Sun God

The Giza Pyramids of ancient Egypt, pictured here, were built along an invisible diagonal in orientation toward Heliopolis, the center of worship for the sun god in ancient Egypt, suggests new research.

From Discovery:

March 24, 2009 -- Some of Egypt's most magnificent pyramids were deliberately designed to follow a pattern of invisible diagonal lines, an Italian study has concluded.

According to Giulio Magli, professor of archaeoastronomy at Milan's Polytechnic University, these invisible lines would connect most of the funerary complexes raised by the kings of the Old Kingdom between 2630 and 2323 B.C.

Airport Body Scans Reveal All

Millimeter wave technology produces whole body images (woman at left, man at right) that reveal what's under your clothes, including Metallic or non-metallic devices and objects are displayed, including weapons, explosives and other items that a passenger is carrying on his/her person. The images are viewed by a Transportation Security Officer in a remote location. According to the TSA: To ensure privacy, the setup "has zero storage capability and images will not be printed stored or transmitted. Once the transportation security officer has viewed the image and resolved anomalies, the image is erased from the screen permanently. The officer is unable to print, export, store or transmit the image." Credit: TSA

From Live Science:

New airport security scanners could become a popular alternative to body searches, but have also prompted some privacy concerns.

Whole-body imaging technologies can see through clothing to reveal metallic and non-metallic objects, including weapons or plastic explosives. They also reveal a person's silhouette and the outlines of underwear.

That hasn't stopped security officials from implementing them. The U.S. Transportation Security Agency (TSA) started using whole-body imaging at six airports this year, and plans are in the works to expand it to airports in several more U.S. cities later this year.

From Watts Up With That?

The sunspot cycle is behaving a little like the stock market. Just when you think it has hit bottom, it goes even lower.

2008 was a bear. There were no sunspots observed on 266 of the year’s 366 days (73%). To find a year with more blank suns, you have to go all the way back to 1913, which had 311 spotless days: plot. Prompted by these numbers, some observers suggested that the solar cycle had hit bottom in 2008.

Maybe not. Sunspot counts for 2009 have dropped even lower. As of March 31st, there were no sunspots on 78 of the year’s 90 days (87%).

From Science Daily:

ScienceDaily (Mar. 31, 2009) — Chemists reported development of what they termed the first economical, eco-friendly process to convert algae oil into biodiesel fuel — a discovery they predict could one day lead to U.S. independence from petroleum as a fuel.

The study was presented recently at the 237th National Meeting of the American Chemical Society.

One of the problems with current methods for producing biodiesel from algae oil is the processing cost, and the New York researchers say their innovative process is at least 40 percent cheaper than that of others now being used. Supply will not be a problem: There is a limitless amount of algae growing in oceans, lakes, and rivers, throughout the world.

Deformed Skull Suggests Human Ancestors Had Compassion

A newly reconstructed deformed fossil skull suggests our human ancestors probably cared for deformed offspring for years.

From Wired Science:

The skull indicates that the child who lived about 530,000 years ago would have been severely handicapped — and yet survived at least five years and possibly several years longer. That suggests the parents or community provided the child with care, despite his or her obvious deformities.

"Her/his pathological condition was not an impediment to receiv[ing] the same attention as any other Middle Pleistocene Homo child," the the team of Spanish researchers write in the Proceedings of the National Academy of Sciences.
