Edmonton Canada Bests All Time Record Low By -12 Degrees, Columnist Questions Climate Situation

From Watts Up With That?

UPDATE: The author’s (Lorne Gunter) claim of breaking a record by -12 degrees is only partially correct. The phrase “smashing the previous March low” should have read “smashing the previous March 10th low”

The previous March record Tmin occurred in 2003 and was -42.2°C details here (Thanks to reader K Stricker for the link) - Anthony

So why are eco types moaning about record highs while ignoring record lows?

By Lorne Gunter, The Edmonton Journal

So far this month, at least 14 major weather stations in Alberta have recorded their lowest-ever March temperatures. I’m not talking about daily records; I mean they’ve recorded the lowest temperatures they’ve ever seen in the entire month of March since temperatures began being recorded in Alberta in the 1880s.

My Comment: I live north of Montreal in the Laurentians. The winters for the past 3-4 years have been very hard, and while we have not broken any records, it has been very very cold. Even the summers have been below normal temperatures. So .... while other parts of the world are experiencing "global warming", this definitely has not been the case here.

Where Does Consciousness Come From?

From Science Daily:

ScienceDaily (Mar. 17, 2009) — Consciousness arises as an emergent property of the human mind. Yet basic questions about the precise timing, location and dynamics of the neural event(s) allowing conscious access to information are not clearly and unequivocally determined.

Some neuroscientists have even argued that consciousness may arise from a single "seat" in the brain, though the prevailing idea attributes a more global network property.

Do the neural correlates of consciousness correspond to late or early brain events following perception? Do they necessarily involve coherent activity across different regions of the brain, or can they be restricted to local patterns of reverberating activity?

Saturn Photographed with Four Moons

With Live Science:

A new Hubble photograph captured a rare alignment of four of Saturn's moons lining up in front of their planet.

The snapshot, taken on Feb. 24 with the NASA/European Space Agency (ESA) Hubble Space Telescope, shows the moons transiting in front of Saturn. The moons, from far left to right, are the white icy moons Enceladus and Dione, the large orange moon Titan, and icy Mimas. Due to the angle of the Sun, they are each preceded by their own shadow.

These rare moon transits only happen when the tilt of Saturn's ring plane is nearly "edge on" as seen from the Earth. Saturn's rings will be perfectly edge on to our line of sight on Aug. 10 and Sept. 4, 2009. Unfortunately, Saturn will be too close to the Sun to be seen by viewers on Earth at that time. This "ring plane crossing" occurs every 14-15 years. In 1995-96 Hubble witnessed the previous ring plane crossing, as well as many moon transits, and helped to discover several new moons of Saturn.

Probe Launches To Map Earth's Gravity In Best Detail Yet

From New Scientist:

A sleek satellite that is set to make the most detailed map of the Earth's gravity took to the skies on Tuesday. The probe is expected to make important contributions to ocean current measurements and climate models.

If all goes well, the satellite will assume an orbit some 285 km above the Earth, gradually falling to an altitude of 268 km, where the probe will take much of its science data. It will remain in orbit for at least two years, beginning science operations in late August or early September when the probe will have sufficient solar power to do its observations.

From Live Science:

Editor's Note: This occasional series of articles looks at the vital things in our lives and the chemistry they are made of.

Oil, the lifeblood of U.S. transportation today, is thought to start with the remnants of tiny organisms that lived millions of years ago, but the exact chemical transformation is somewhat mysterious. New research is looking at the role played by microorganisms that live in the deep dark bowels of the Earth.

A minority of scientists say otherwise, but most geologists think that the petroleum we pump from the ground (and later refine into gasoline and other fuels) comes predominantly from the fossils of marine life, such as algae and plankton.

What Happens At The Moment Of Death?

Peering Down The Tunnel Beyond Death -- Globe And Mail

Hollywood favours, for simplicity's sake, the instant flat-line death; the hero gasps a brilliant line, his eyes dim and he's gone. But in real life, dying has more drama. The heart and lungs quit, the blood, carrying its life-giving oxygen, stops flowing and the brain, without its generator, chugs to a standstill. Abandoned in the dark, the cells take their last stand, firing off chemicals like distress flares. When no rescue comes, they begin to suffocate one by one. The cell membranes rupture, spilling out the insides. Or they implode.

Yet now and then there is Hollywood-style rescue: The heart is kick-started back to life, blood pumps, the brain sucks in oxygen in time to save itself. We've all heard the stories of people who return from the edge of death: bright tunnels, visions of dead relatives and, most logic-defying of all, floating above themselves watching the doctors trying to save them.

From Science Daily:

ScienceDaily (Mar. 16, 2009) — A herd of young birdlike dinosaurs met their death on the muddy margins of a lake some 90 million years ago, according to a team of Chinese and American paleontologists that excavated the site in the Gobi Desert in western Inner Mongolia.

The Sudden sudden death of the herd in a mud trap provides a rare snapshot of social behavior. Composed entirely of juveniles of a single species of ornithomimid dinosaur (Sinornithomimus dongi), the herd suggests that immature individuals were left to fend for themselves when adults were preoccupied with nesting or brooding.

People With Higher IQs Live Longer

From The Telegraph:

People with higher IQs are more likely to live into healthy old age, according to a study.

Unfortunately, those who do not perform so well in intelligence tests could suffer a higher risk of heart disease, fatal accidents and suicide.

The discovery was made after researchers looked into the medical records of one million Swedish army conscripts.

After taking into account whether they had grown up in a safer, more affluent environment, they established the connection between IQ and mortality.

One of the researchers, Dr David Batty, said the statistics showed "a strong link between cognitive ability and the risk of death."

He added: "People with higher IQ test scores tend to be less likely to smoke or drink alcohol heavily. They also eat better diets, and they are more physically active. So they have a range of better behaviours that may partly explain their lower mortality risk."

From The Guardian:

The giant meat-eating reptile, known as a pliosaur, had a bite four times as powerful as T. rex. The second creature, on the other hand, may be the least scary dinosaur ever discovered.

The remains of a giant meat-eating sea monster that patrolled the oceans during the reign of the dinosaurs have been unearthed on an island in the remote Arctic archipelago of Svalbard.

Norwegian fossil hunters recovered the rear half of the formidable reptile's skull in south-west Spitsbergen in what has been described as one of the most significant Jurassic discoveries ever made.

The predator has been identified as a new species of pliosaur, a group of extinct aquatic reptiles that had huge skulls, short necks and four flippers to power them through the water.

Watery Asteroids May Explain Why Life Is 'Left-Handed'

Image: Amino acids, such as isovaline (illustrated), come in left- and right-handed forms, but almost every living organism on Earth uses left-handed forms. New research suggests that water on asteroids amplified a bias - possibly caused by polarised starlight - towards left-handed amino acids (Illustration: NASA/Mary Pat Hrybyk-Keith)

From New Scientist:

Soggy rocks hurtling through the solar system gave life on Earth an addiction to left-handed proteins, according to a new study. The research suggests that water on asteroids amplified left-handed amino acid molecules, making them dominate over their right-handed mirror images.

Curiously, almost every living organism on Earth uses left-handed amino acids instead of their right-handed counterparts. In the 1990s, scientists found that meteorites contain up to 15% more of the left version too. That suggests space rocks bombarding the early Earth biased its chemistry so that life used left-handed amino acids instead of right.

From Popular Mechanics:

NASA's Orion won't be ready until at least 2015, but the current space shuttle is due to retire next year. Meet the seven international spacecraft from the world's space fleet that could inherit the job of ferrying supplies into space.

The space shuttle is due for retirement in 2010, and NASA’s next spaceship, Orion, won’t be available until at least 2015. That will leave a five-year gap during which NASA astronauts and space-station cargo will be grounded unless they find other ways to get to orbit. In the past, NASA has cadged rides off its former arch-rival, the Russian Federal Space Agency, and its Soyuz (for astronauts) and Progress (for cargo) spacecraft. But relations between the U.S. and Russia are cooling, raising the very real prospect that Congress will forbid NASA to buy spaceflights from Russia. NASA has stepped up its support of two U.S. companies, Space Exploration Technologies (SpaceX) and Orbital Sciences Corporation, that hope to have unmanned cargo spaceships ready for launch by 2010. (See details below.) Even if these companies succeed, NASA will still have to rely on Soyuz for manned flights. But maybe not for long. Here’s a roundup of seven rides to low Earth orbit besides the space shuttle and Soyuz that could be available for space-station flights.

Gallery: The Top 10 Failed NASA Missions

9. Demonstration for Autonomous Rendezvous Technology (DART) Spacecraft : The Mission: Upset with the expense and risk of launching the shuttle every time a satellite needed maintenance, NASA created the DART to show that a robotic satellite could dock with other satellites. DART was supposed to autonomously navigate towards, and then rendezvous with, an existing communications satellite.

The Problem: And did it ever rendezvous! The computer controlling DART incorrectly estimated the distance between the two satellites, causing DART to bump right into the other satellite! DART then used up all of its fuel, eventually crashing into the ocean.

Trend: Daughters Follow Dads' Footsteps

From Live Science:

Women nowadays are three times more likely than those born a century ago to do what men have done for millennia — follow their father's footsteps into his line of work, a newly announced study finds.

One way or another, fathers and daughters have been paying more attention to each other, and daughters picked up job cues or assistance from dads, as more and more women entered the labor force, the research suggests.

Just under 6 percent of women born from 1909 to 1915 worked in their father's occupation, while around 20 percent of women born in the mid-1970s do so (they are in their early 30s now), the researchers found.

Global Hurricane Activity Has Decreased To The Lowest Level In 30 Years.

(Click the Above Image to Enlarge)
Figure: Global 24-month running sum time-series of
Accumulated Cyclone Energy updated through March 12, 2009.

From Watts Up With That?

Very important: global hurricane activity includes the 80-90 tropical cyclones that develop around the world during a given calendar year, including the 12-15 that occur in the North Atlantic (Gulf of Mexico and Caribbean included). The heightened activity in the North Atlantic since 1995 is included in the data used to create this figure.

As previously reported here and here at Climate Audit, and chronicled at my Florida State Global Hurricane Update page, both Northern Hemisphere and overall Global hurricane activity has continued to sink to levels not seen since the 1970s. Even more astounding, when the Southern Hemisphere hurricane data is analyzed to create a global value, we see that Global Hurricane Energy has sunk to 30-year lows, at the least. Since hurricane intensity and detection data is problematic as one goes back in time, when reporting and observing practices were different than today, it is possible that we underestimated global hurricane energy during the 1970s. See notes at bottom to avoid terminology discombobulation.

From The Daily Mail:

Old age is often blamed for causing us to misplace car keys, forget a word or lose our train of thought.

But new research shows that many well-known effects of ageing may start decades before our twilight years.

According to scientists, our mental abilities begin to decline from the age of 27 after reaching a peak at 22.

The researchers studied 2,000 men and women aged 18 to 60 over seven years. The people involved – who were mostly in good health and well-educated – had to solve visual puzzles, recall words and story details and spot patterns in letters and symbols.

Similar tests are often used to diagnose mental disabilities and declines, including dementia.

“In a very cynical way, it’s a triumph for science because at last we have stabilized something –- namely the estimates for the carrying capacity of the planet, namely below 1 billion people,” said Dr. Schellnhuber, who has advised German Chancellor Angela Merkel on climate policy and is a visiting professor at Oxford.

From Physorg.com:

Researchers at the University of Miami and at the Universities of Tokyo and Tohoku, Japan, have been able to prove the existence of a "spin battery," a battery that is "charged" by applying a large magnetic field to nano-magnets in a device called a magnetic tunnel junction (MTJ). The new technology is a step towards the creation of computer hard drives with no moving parts, which would be much faster, less expensive and use less energy than current ones. In the future, the new battery could be developed to power cars.

The study will be published in an upcoming issue of Nature and is available in an online advance publication of the journal.

The device created by University of Miami Physicist Stewart E. Barnes, of the College of Arts and Sciences and his collaborators can store energy in magnets rather than through chemical reactions. Like a winding up toy car, the spin battery is "wound up" by applying a large magnetic field --no chemistry involved. The device is potentially better than anything found so far, said Barnes.

From ABC News:

All Those Hours at the Piano Paid Off: A Musician's Brain Recognizes Sound That Carries Emotion.

All those hours practicing the piano pay off big time by biologically enhancing a person's ability to quickly recognize and mentally process sounds that carry emotion, according to a new study.

The study, from Northwestern University in Evanston, Ill., offers a new line of evidence that the brain we end up with is not necessarily the same brain we started out with.

"We are measuring what the nervous system has become, based on an individual's experience with sound," Nina Kraus, director of the university's groundbreaking Auditory Neuroscience Laboratory, said in a telephone interview.

Happy 20th Birthday, World Wide Web

TIM BERNERS-LEE (2001)

The Mind Behind The Web -- Scientific American

Tim Berners-Lee invented the World Wide Web and continues to shape its frantic evolution. He's neither rich nor famous, which is fine by him.

It is a cool morning in April 1999, and 1,500 computer scientists, university faculty, and industry CEOs are streaming into a vast fieldhouse at the Massachusetts Institute of Technology in Cambridge, outside Boston. They grab coffee and seat themselves for a keynote speech that will cap the 35th anniversary celebration of M.I.T.'s Laboratory for Computer Science, the fount of so many creations that have driven the computer revolution.

From a makeshift stage, lab director Michael Dertouzos calls out, "We've had a great party! Now the man you've been waiting for: Tim Berners-Lee, inventor of the World Wide Web." The crowd hushes and arches forward, for they know the name but not the man. Out from the shadows strides a sprightly 43-year-old Briton, smiling beneath a short crop of blond hair.

Friday The 13th Strikes Again -- Two Months In A Row

Traditionally an omen of ill fortune, a black cat crosses a Palermo, Italy, street in an undated photo. Unlike its feline fellow resident of the bad luck hall of fame, Friday the 13th doesn't have nine lives—it can't even exist more than three times a year, thanks to the eccentricities of the calendar.

From The National Geographic:

You're not having a nightmare. It really is Friday the 13th again.

For the first time in 11 years, Friday the 13th is falling in two consecutive months. This double threat can only occur in certain non-leap years and only in a February-March combination. Look for it—or avoid it—again in 2015.

The double whammy isn't the only Friday the 13th claim to infamy for 2009, a particularly tough year for superstitious minds.

The ominous date falls on three Fridays this year: February 13; this Friday, March 13; and again on November 13.

But three Friday the 13ths is the yearly maximum, as long as societies continue to mark time with the Gregorian calendar, which Pope Gregory XIII ordered the Catholic Church to adopt in 1582.

From Popular mechanics:

This morning, the three astronaut residents of the International Space Station scurried for safety in a Soyuz module, preparing for a possible impact with a piece of space junk—the motor of a satellite-carrying rocket. If struck, the station could experience a drop in air pressure that could kill all inhabitants. The event raises a thorny legal question: who is responsible for damages caused by space junk? Glenn Reynolds, a contributing Editor to Popular Mechanics and professor of space law at the University of Tennessee, outlines the complexities of orbital tort.

This morning, the three astronaut residents of the International Space Station scurried for safety in a Soyuz module, preparing for a possible impact with a piece of space junk—a 1/3-in.-wide part of a motor of a satellite-carrying rocket. If struck, the station could experience a drop in air pressure that could kill all inhabitants. NASA usually moves the ISS out of the orbit of debris, but some junk with erratic orbits can defeat tracking and surprise mission control, as happened during this incident. The debris missed the ISS and the astronauts exited the Soyuz “life raft,” but the junk is believed to have come within the station’s safety zone of 2.8 miles. The event raises a thorny legal question: Who is responsible for damages caused by space junk?

Artificial Photosynthesis: Turning Sunlight Into Liquid Fuels Moves A Step Closer

Under the fuel through artificial photosynthesis scenario, nanotubes embedded within a membrane would act like green leaves, using incident solar radiation (H³) to split water molecules (H2O), freeing up electrons and oxygen (O2) that then react with carbon dioxide (CO2) to produce a fuel, shown here as methanol (CH3OH). The result is a renewable green energy source that also helps scrub the atmosphere of excessive carbon dioxide from the burning of fossil fuels.

From Science Daily:

ScienceDaily (Mar. 12, 2009) — For millions of years, green plants have employed photosynthesis to capture energy from sunlight and convert it into electrochemical energy. A goal of scientists has been to develop an artificial version of photosynthesis that can be used to produce liquid fuels from carbon dioxide and water.

Researchers with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have now taken a critical step towards this goal with the discovery that nano-sized crystals of cobalt oxide can effectively carry out the critical photosynthetic reaction of splitting water molecules.

Humans Respond to Scent of Fear

From Live Science:

Moviegoers might want to scoff a bit less when characters talk about the scent of fear. Women exposed to fear chemicals in male sweat tended to see ambiguous faces as being more fearful, according to a new study.

Such research shows for the first time how even the smell of fear can affect how people interpret what they see right in front of them. That fits with previous studies showing that visual and facial cues can affect human emotion and interpretation – but mainly when the situation seems uncertain.

From The Guardian:

There are 109 million more hungry people in poor countries now than there were just five years ago. But the answer is not more food aid, writes Pedro A. Sanchez

In recent decades, it seemed the struggle against world hunger was finally meeting with some success. But the number of undernourished people is growing again. According to the UN Food and Agriculture Organisation, the number of hungry people in poor countries has increased by 109 million to 963 million since 2004. Unicef estimates that each day 300 million children go to bed hungry.

From Nature News:

Two researchers have developed battery cells that can charge up in less time than it takes to read the first two sentences of this article. The work could eventually produce ultra-fast power packs for everything from laptop computers to electric vehicles.

Byoungwoo Kang and Gerbrand Ceder of the Massachusetts Institute of Technology in Cambridge have found a way to get a common lithium compound to release and take up lithium ions in a matter of seconds. The compound, which is already used in the electrodes of some commercial lithium-ion batteries, might lead to laptop batteries capable of charging themselves in about a minute. The work appears in Nature1 this week.
