Massive Solar Storms of the Future Could Reap Katrina-Scale Devastation

Plasma of the Sun I'm looking at you, Earth Hinode JAXA/NASA

From Popular Science:

If storms as strong as the biggest recorded in the last few two centuries, our electronics-dependent world of today could be in trouble.

No electricity, no running water, and no phone service for millions of people. That scenario could easily become reality if a solar storm as intense as those found throughout the history of our planet were to strike Earth today. NPR reported on FEMA's recent simulation of such a storm, and the grim conditions it uncovered.

From Science Daily:

Science Daily (Mar. 2, 2010) — The Feb. 27 magnitude 8.8 earthquake in Chile may have shortened the length of each Earth day.

JPL research scientist Richard Gross computed how Earth's rotation should have changed as a result of the Feb. 27 quake. Using a complex model, he and fellow scientists came up with a preliminary calculation that the quake should have shortened the length of an Earth day by about 1.26 microseconds (a microsecond is one millionth of a second).

Titanic vs. Lusitania: Time Determined Who Survived

The RMS Titanic being towed

From Live Science:

The time people have during survival situations might affect whether they behave selfishly or socially. Examining two shipwrecks, the Titanic and the Lusitania, researchers recently found the longer passengers had to react to the disaster, the more likely they were to follow social mores. The less time, the more selfishly passengers behaved.

The result: It was every man for himself aboard the rapidly sinking Lusitania, and so the fittest were the most likely to survive that accident. During the lengthy Titanic shipwreck, women in their reproductive years were the most likely to make it, while men of the same age had a lower probability of surviving.

From Technology Review:

The old mechanism for funding the commercialization of new technologies is in trouble.

In the summer of 1996, Silicon Valley venture capitalists put a few million dollars into a telecom-equipment startup called Juniper Networks. Three years later, after a few more rounds of funding and the release of its first product, Juniper enjoyed an initial public offering of shares, or IPO. At the end of its first day of trading, it was worth nearly $5 billion, and within nine months, it was worth almost 10 times that. The original venture investors, meanwhile, were able to walk away with profits of better than 10,000 percent.

Coldest Winter In UK For More Than 30 Years... But Met Office Defends Its Long Range Forecast

Mothers tow children on their sledges in Hampshire, in January. The Met Office has confirmed that 2009/10 winter was the coldest since 1978/79

From The Daily Mail:

Perhaps someone should ask workers at the Met Office to take a rain check on their optimism.

After predicting just a 20 per cent chance of a colder than average winter, they were left embarrassed again when official figures revealed it was the coldest for more than 30 years.

Temperatures in December, January and February struggled to stay above zero, with the UK's average a chilly 1.5c (35f), making it the deepest freeze since 1978-79.

From Time Magazine:

It's hard to remember your manners when you think you're about to die. The human species may have developed an elaborate social and behavioral code, but we drop it fast when we're scared enough — as any stampeding mob reveals.

That primal push-pull is at work during wars, natural disasters and any other time our hides are on the line. It was perhaps never more poignantly played out than during the two greatest maritime disasters in history: the sinking of the Titanic and the Lusitania. A team of behavioral economists from Switzerland and Australia have published a new paper in the Proceedings of the National Academy of Sciences (PNAS) that takes an imaginative new look at who survived and who perished aboard the two ships, and what the demographics of death say about how well social norms hold up in a crisis.

Where The Quakes In Chile Struck

This map of topography and water depth along the Chilean coast shows quake locations and magnitudes (black circles), with lighter colors indicating higher elevation on land and shallower depth in the water. The boundary where the two tectonic plates converge is marked by a red line. Also there is a trench where the Nazca Plate begins to dive beneath the South America Plate. When these plates get locked together for any time the pressure will eventually break, resulting in an earthquake like the 8.8 magnitude temblor on Feb. 27. Credit: NASA Earth Observatory.

From Live Science:

The 8.8-magnitude earthquake that devastated parts of Chile was the result of a collision between two giant slabs of Earth.

The jolt occurred along a so-called subduction zone, where one tectonic plate dives beneath another. In this case, the Nazca Plate is plowing under the South America Plate at an average rate of 3 inches (80 millimeters) a year. In addition to the Feb. 27 earthquake and others, the plate collision gives rise to the spectacular Andes Mountains.

Year Of The Laser


From Technology Review:

The laser, a device used in everything from astrophysics to biology, was invented 50 years ago.

This year is the 50th anniversary of the laser, a device used in applications from performing precise surgical procedures to measuring gravitational waves. In 1917, Albert Einstein proposed that a photon hitting an atom in a high energy state would cause the atom to release a second photon identical in frequency and direction to the first. In the 1950s, scientists searched for a way to achieve this stimulated emission and amplify it so that a group of excited atoms would release photons in a chain reaction. In 1959, American physicist Gordon Gould publicly used the term “light amplification by stimulated emission of radiation” for the first time. A year later, scientists demonstrated the first working optical laser.

Chile Quake Among Most Powerful Ever



From Discovery News:

The so-called megathrust quake that rocked the western coast of South America is the most powerful of its kind.

THE GIST:

* The 8.8-magnitude earthquake is similar to the 2004 Indian Ocean temblor that triggered devastating tsunamis.
* Called megathrusts, these quakes occur when one tectonic plate dives beneath another.
* The Chile tremor unleashed about 50 gigatons of energy.

The huge earthquake that struck off the coast of Chile belongs to an "elite class" of mega earthquakes, experts said, and is similar to the 2004 Indian Ocean temblor that triggered deadly tsunami waves.

The Founding Fathers liked happiness so much they considered pursuing it an inalienable right – but maybe that wasn't such a good idea. Happiness seems to make people more selfish, the latest in a series of revelations suggesting it changes how you think – and not in a good way.

Psychologist Joe Forgas at the University of New South Wales in Sydney, Australia, who has led many of these studies, suggests that happiness's negative effects all stem from a cheery mood's tendency to lull you into feeling secure. This makes you look inwards and behave both more selfishly and more carelessly.

From The Independent:

It is fortunate that one of the biggest earthquakes in recent history has generated only relatively small tsunamis that crossed the Pacific Ocean from Chile to Japan. This is almost certainly because the rupture that generated the earthquake occurred quite deep in the Earth's crust.

The size of a tsunami, which means "harbour wave" in Japanese, is directly related to the volume of water that is displaced during the movement of the seabed during an earthquake. The bigger the amount of water that is moved up or down, the bigger the tsunami that is likely to be created.

From The Guardian:

Guitar hero's 'mixed-handedness' was secret to his genius, argues American psychologist.

Was Jimi Hendrix's ambidexterity the secret to his talent? This is the question explored in a new paper by psychologist Stephen Christman (via TwentyFourBit), who argues that Hendrix's versatility informed not just his guitar-playing – but his lyrics too.

According to Christman, who is based at the University of Toledo, Hendrix was not strictly left-handed. Although he played his right-handed guitar upside down, and used his left hand to throw, comb his hair and hold cigarettes, Hendrix wrote, ate and held the telephone with his right hand. He was, Christman argues, "mixed-right-handed". And this "mixed"-ness, signaling better interaction between the left and right hemispheres of the guitarist's brain, suffused every part of his music.
