It’s Official: La Niña Is Back

(Click the Image to Enlarge)

From Watts Up With That?:

UPDATE: There’s some question about NCEP’s communications intent with this paper. While they cite “La Niña conditions” in the language, and the visual imagery lends itself to that, the numerical threshold of ONI hasn’t been reached, as has been pointed out in comments. Yet NCEP made no mention in the summary that the threshold had not been reached. I’ll see if I can locate the authors and get a clarification. - Anthony

In a document published January 19th, NOAA’s Climate Prediction Center (NCEP) has officially put the stamp on the cold water conditions we’ve seen growing in the equatorial mid and eastern Pacific. I first reported on this on December 4th, 2008. This does not bode well for California’s drought conditions, which are likely to continue due to this renewed La Niña event.

From Live Science:

The frozen desert interior of Antarctica was thought to be the lone holdout resisting the man-made warming affecting the rest of the globe, with some areas even showing signs of cooling.

Some global warming contrarians liked to point to inner Antarctica as a counter-example. But climate researchers have now turned this notion on its head, with the first study to show that the entire continent is warming, and has been for the past 50 years.

"Antarctica is warming, and it's warming at the same rate as the rest of the planet," said study co-author Michael Mann of Penn State University.

Quotas For Women In Science?

In ‘Geek Chic’ And Obama, New Hope For Lifting Women In Science -- New York Times

With the inauguration of an administration avowedly committed to Science as the grand elixir for the nation’s economic, environmental and psycho-reputational woes, a number of scientists say that now is the time to tackle a chronic conundrum of their beloved enterprise: how to attract more women into the fold, and keep them once they are there.

Researchers who have long promoted the cause of women in science view the incoming administration with a mix of optimism and we’ll-see-ism. On the one hand, they said, the new president’s apparent enthusiasm for science, and the concomitant rise of “geek chic” and “smart is the new cool” memes, can only redound to the benefit of all scientists, particularly if the enthusiasm is followed by a bolus of new research funds. On the other hand, they said, how about appointing a woman to the president’s personal Poindexter club, the President’s Council of Advisers on Science and Technology? The designated leaders so far include superstars like Harold Varmus, a Nobel laureate, and Eric Lander, genome meister.

Why People Fake Their Deaths

From Live Science:

When people die, sometimes it's hard to believe they are really gone — and for good reason.

Rumors of faked deaths have followed many famous people, including comedian Andy Kaufman, Elvis Presley, John F. Kennedy, and (up until October 2008) pilot Steve Fossett. Rumors and conspiracy theories aside, faked deaths are a perpetually popular subject in fiction, from Mark Twain's Tom Sawyer and Huckleberry Finn to today's soap operas.

And, of course, it happens in real life. Last week, Wall Street investor Marcus Schrenker disappeared while flying his plane over Alabama. He radioed a distress call, and his plane was found — without him — in a swamp. He was later discovered in a campground and arrested.

Source Of Moon's Magnetism Found

From Yahoo News/Space.com:

Moon rocks delivered to Earth by Apollo astronauts held a mystery that has plagued scientists since the 1970s: Why were the lunar rocks magnetic?

Earth's rotating, iron core produces the planet's magnetic field. But the moon does not have such a setup.

Now, scientists at MIT think they have a solution. Some 4.2 billion years ago, the moon had a liquid core with a dynamo (like Earth's core today) that produced a strong magnetic field. The moon's magnetic field would have been about 1-50th as strong as Earth's is today, the researchers say.

The 'Toxic' Web Generation: Children Spend Six Hours A Day In Front Of Screens

From The Daily Mail:

Youngsters are shunning books and outdoor games to spend up to six hours a day in front of a screen, a survey has revealed.

Children as young as five are turning their bedrooms into multi-media 'hubs' with TVs, computers, games consoles, MP3 players and mobile phones all within easy reach.

The trend triggered warnings that the next generation will struggle to compete in the adult world because they lack reading and writing skills.

At the same time their mastery of technology is not widely appreciated by their parents.

The market research involving 1,800 children aged five to 16 found that they spend an average of 2.7 hours a day watching TV, 1.5 on the internet and 1.3 playing on games consoles, although in some cases these activities are simultaneous, such as watching TV while playing on a console.

In contrast, youngsters spend just over half an hour reading books, according to the survey by ChildWise.

Almost a third take a games console to bed rather than a book, while a quarter never read in their own time.

From Popular Mechanics:

Miraculous. That’s the descriptor that continues to pop up in many accounts of the successful landing of US Air Flight 1549 in the Hudson River on Thursday. Aviation experts see the events a little differently. What happened to captain Chesley Sullenberger III and his crew was a piece of tremendously bad luck, mitigated by a few turns of equally stunning good fortune and a sequence of smart decisions by the captain and his crew. Here’s a pilot’s eye view of what went right during the emergency, the landing and the rescue that saw all 150 passengers rescued safely from the plane. –Allen St. John

Heavy Rains Damage Peru's Nazca Lines

From Yahoo News/AP:

LIMA, Peru – Heavy rains have damaged part of one of Peru's top tourist destination, depositing clay and sand on mysterious figures etched in the desert sand by indigenous groups centuries ago, an archaeologist said Monday.

The rains, which are uncommon on Peru's dry coastal desert, washed off the nearby Panamerican highway and pushed sand on top of three fingers of a geoglyph in the famed Nazca lines, said Mario Olaechea of Peru's National Culture Institute. The fingers form part of a pair of hands.

Olaechea told The Associated Press that the damage is minor and the institute plans to clear the material and restore the geoglyph.

If There IS Life On Mars, This Is Where It Lives

Plumes of up to 19,000 tons of methane, pictured red,
were detected in Mars' northern hemisphere

From The Daily Mail:

If there is life on Mars as NASA scientists claim, this is where it lives.

This extraordinarily detailed picture shows exactly where the most methane, taken as an indication of life, can be found.

Appropriately enough for the sphere dubbed the Red Planet , the scarlet areas are the places where scientists have detected the most of the gas.

The picture was released by NASA just days after the U.S. space agency confirmed the presence of methane on Mars.

It is the first 'definitive proof' of plumes of the gas seeping from the planet's northern hemisphere.

And it is the strongest hint yet that alien microbes could be thriving deep below the red, dusty surface.

On Earth, 90 per cent of the methane produced is released by living organisms far beneath the soil.

'It might be possible for similar organisms to survive for billions of years below the permafrost layer on Mars, where water is liquid, radiation supplies energy, and carbon dioxide provides carbon,' said NASA scientist Professor Michael Mumma.

From Watts Up With That:

Well John Christy gave me a lot to think about in satellite temp trends as far as an improved correction over my last post. Steve McIntyre pitched in some comments as well. It is going to take a bit to work out the details of that for me but I think I can produce an improved accuracy slope over my last posts. In the meantime, I downloaded sunspot numbers from the NASA.

Cycles are interesting things. There are endless cycles in nature, orbits, ocean temp shifts, solar cycles, magnetic cycles the examples are everywhere. What makes a cycle unusual is also an interesting topic. Some solar scientists have claimed that our current solar cycle is not unusual by the record. They are certainly the experts but recently the experts have been forced to update their predictions for the next solar cycle.

From Yahoo News/AFP:

ROME (AFP) – Italian scientists are trying to get Galileo's DNA in order to figure out how the astronomer forged groundbreaking theories on the universe while gradually becoming blind, a historian said Monday.

Scientists at Florence's Institute and Museum of the History of Science want to exhume the body of 17th Century astronomer Galileo Galilei to find out exactly what he could see through his telescope.

The Italian astronomer -- who built on the work of predecessor Nicolaus Copernicus to develop modern astronomy with the sun as the centre of the universe -- had a degenerative eye disease that eventually left him blind.

DNA Testing May Unlock Secrets Of Medieval Manuscripts

From E! Science News:

Thousands of painstakingly handwritten books produced in medieval Europe still exist today, but scholars have long struggled with questions about when and where the majority of these works originated. Now a researcher from North Carolina State University is using modern advances in genetics to develop techniques that will shed light on the origins of these important cultural artifacts. Many medieval manuscripts were written on parchment made from animal skin, and NC State Assistant Professor of English Timothy Stinson is working to perfect techniques for extracting and analyzing the DNA contained in these skins with the long-term goal of creating a genetic database that can be used to determine when and where a manuscript was written. "Dating and localizing manuscripts have historically presented persistent problems," Stinson says, "because they have largely been based on the handwriting and dialect of the scribes who created the manuscripts – techniques that have proven unreliable for a number of reasons."

Growing Bird Populations Show Conservation Successes

The Canada goose (Branta canadensis), which is sometimes incorrectly referred to as the Canadian goose, has a wingspan of 50 to 67 inches (127 to 170 centimeters) and can weigh from more than 6 pounds to nearly 20 pounds (3 kg to 9 kg). Credit: Stock.xchng.

From Live Science:

At a time when scientists are sounding ever more frequent alarms on the potential extinction of this creature or that, yesterday's collision with a flock of geese that put an airliner in the Hudson River is a reminder that some species are doing just fine.

Many birds have been faring well in the United States, even in urban environments (and in some cases especially in them), over the past few decades, say two bird experts and conservationists.

"Birds are increasing and that's good," said Kevin McGowan of the Cornell Laboratory of Ornithology in New York. "People have worked hard to do that kind of thing. Most people like it. We don't always hear enough about the fact that a lot of things are doing well."

From Science Daily:

ScienceDaily (Jan. 18, 2009) — Scientists may have solved one of the most longstanding astrophysical mysteries of all times: How massive stars – up to 120 times the mass of our sun – form without blowing away the clouds of gas and dust that feed their growth.

New research by Lawrence Livermore National Laboratory, University of California, Santa Cruz and UC Berkeley has shown how a massive star can grow despite outward-flowing radiation pressure that exceeds the gravitational force pulling material inward. The study appears in the Jan. 15 online edition of Science Express.

The Afterlife Of Near-Death

From International Herald Tribune:

Every experienced flier has sensed a whisper of death in a blast of turbulence at 25,000 feet, and many will swear they've heard their names called, loud and clear.

It's not a moment people forget.

"All I could think about," said a 50-year old nurse who'd recently been in a plane that lost an engine, "was my garage. How I hadn't cleaned it, and how messy it would be when someone came in and saw it. It's crazy what you think about."

The mind reels in the presence of death.

From the shore and TV screens, the evacuation of a US Airways jet that ditched in the Hudson River on Thursday looked almost stage-managed, a slow-motion rescue complete with heroes and zero death.

Liquid Wood Is Plastic of Tomorrow, Say Scientists

The new substance would be safe for use in toys

From Deutsche Welle:

Plastic was one of the great innovations of the 20th century, but German scientists believe a new invention, liquid wood, could soon supplant the chemical in terms of everyday usefulness.

Though it has proven to be extremely useful in the modern world, plastic still has a number of negative selling points. It is non-biodegradable and can contain carcinogens and other toxic substances that can cause cancer.

It is also based on petroleum, a non-renewable resource that will soon be harder to come by. Increases in the price of crude oil leads to parallel rises in the price of plastics.

But there is a new chemical invention that could do away with these long-standing concerns.

Science Closing In On Cloak Of Invisibility

From Breitbart/AP:

WASHINGTON (AP) - They can't match Harry Potter yet, but scientists are moving closer to creating a real cloak of invisibility.

Researchers at Duke University, who developed a material that can "cloak" an item from detection by microwaves, report that they have expanded the number of wavelengths they can block.

Last August the team reported they had developed so-called metamaterials that could deflect microwaves around a three-dimensional object, essentially making it invisible to the waves.

The system works like a mirage, where heat causes the bending of light rays and cloaks the road ahead behind an image of the sky.

The researchers report in Thursday's edition of the journal Science that they have developed a series of mathematical commands to guide the development of more types of metamaterials to cloak objects from an increasing range of electromagnetic waves.

From Science Daily:

ScienceDaily (Jan. 15, 2009) — Two independent groups have simultaneously made the first-ever ground-based detection of extrasolar planets thermal emissions. Until now, virtually everything known about atmospheres of planets orbiting other stars in the Milky Way has come from space-based observations.

These new results open a new frontier to studying these alien worlds and are especially critical because the major space-based workhorse to these studies, the Spitzer telescope, will soon run out of cryogens, highly limiting its capabilities.

From Live Science:

Early reports suggest that a bird strike caused a jet plane to crash in the Hudson River near Manhattan today, leaving questions about how a little flying animal could down a big airliner.

More than 200 people have been killed worldwide as a result of wildlife strikes with aircraft since 1988, according to Bird Strike Committee USA, and more than 5,000 bird strikes were reported by the U.S. Air Force in 2007. Bird strikes, or the collision of an aircraft with an airborne bird, tend to happen when aircraft are close to the ground, which means just before landing or after take-off, when jet engines are turning at top speeds.
