Climate change spawns the incredible shrinking ant (Reuters)

HONG KONG (Reuters) ? Plants and animals are shrinking because of warmer temperatures and lack of water, researchers said on Monday, warning it could have profound implications for food production in years ahead.

"The worst-case scenarios ... are that food crops and animals will shrink enough to have real implications for food security," Assistant Professor David Bickford, of the National University of Singapore's biological sciences department, said.

Bickford and colleague Jennifer Sheridan trawled through fossil records and dozens of studies which showed that many species of plants and creatures such as spiders, beetles, bees, ants and cicadas have shrunk over time in relation to climate change.

They cited an experiment showing how shoots and fruit are 3 to 17 percent smaller for every degree Celsius of warming in a variety of plants.

Each degree of warming also reduces by 0.5 to 4 percent the body size of marine invertebrates and 6 to 22 percent of fish.

"Survival of small individuals can increase with warmer temperatures, and drought conditions can lead to smaller offspring, leading to smaller average size," they wrote in their paper which was published in the journal, Nature Climate Change, on Monday.

"Impacts could range from food resources becoming more limited (less food produced on the same amount of land) to wholesale biodiversity loss and eventual catastrophic cascades of ecosystem services," Bickford wrote.

"We have not seen large-scale effects yet, but as temperatures change even more, these changes in body size might become much more pronounced - even having impacts for food security."

Acer Aspire S3

The Acer Aspire S3 ($899.99 direct) is the first ultrabook in the PCMag Labs, the first of many in the next few months. If this sliver of a laptop is the shape of things to come, consider us excited. This new breed of laptop checks off all of the boxes Intel has laid out for the ultrabook category?ultra-thin, ultra-fast, and ultra-affordable, with more than 5 hours of battery life. Compared with similar laptops and the few Ultrabooks we've spent time with, like the Asus Zenbook UX31 ($1,099 direct) and Lenovo IdeaPad U300s ($1,199 direct) (stay tuned for our review of both), it falls short on a couple features, but it still gives you a slim, mobile laptop for less than premium competitors.

A Word on Ultrabooks
When Intel announced the guidelines for ultrabooks, it became clear that it intended to create a new laptop sub-category that most closely resembled the specs of the Apple MacBook Air 13-inch (Thunderbolt)'s ($1299.99 direct, 4 stars), with requirements about thickness (under 0.83 inch), battery life (at least 5 hours), and faster boot times that would rely on Intel's Rapid Start technology. Intel has also made it clear that it wants ultrabooks to carry sub-$1000 price tags.

There are laptops that meet some of these requirements?most notably the Apple MacBook Air 13-inch (Thunderbolt)?but this unit is the first that meets all of them. The Samsung Series 9 hits plenty of these points, but it costs far more and lacks Intel's Rapid Start technology. Thus, while the MacBook Air 13-inch and Samsung Series 9 (NP900X3A) ($1,599 street, 4 stars) have many similarities, they are not ultrabooks under Intel's definition. So while we may compare the Acer Aspire S3 to, say, the Editors' Choice Toshiba Portege R835-P50X ($889.99 list, 4.5 stars), it's still, technically speaking, in a category by itself. Until there's an opportunity to dig into the other ultrabooks recently announced, like the Asus Zenbook UX31, we won't be able to compare the Acer Aspire to its closest competitors on anything but a superficial level.

Design
Like the Apple MacBook Air 13-inch (Thunderbolt), the Aspire S3 is ultra-thin, measuring a scant 0.51 inch thick, not including a bit of thickness added by the four foam-rubber feet underneath. It measures 0.7 by 12.6 by 8.5 inches (HWD) , making it small enough to slip into a backpack or large purse, while adding less bulk than a single-subject college ruled notebook. It's also extremely light, at a featherweight 2.94 pounds, which is barely more that the MacBook Air 13-inch (2.9 pounds).

One of the first differences you'll notice once you get your hands on the Aspire S3 is in how it feels. Though its magnesium lid and silvery color scheme resembles laptops with all-metal construction, the rest of the chassis (including the palm rest) is made of plastic. Like the MacBook Air 13-inch, it's thin and lightweight, but the MacBook feels solid and luxurious, while the Aspire S3 feels less substantial.

The 13.3-inch widescreen display?at 450 nits?is even brighter than the screen found on the Samsung Series 9, thanks to an LED-backlit screen. The 1366-by-768 resolution doesn't match the 1,440-by-900 one on the MacBook Air, or the 1,600-by-900 screen on the Asus Zenbook UX31. It also has pretty narrow viewing angles, and anyone attempting to share the screen will likely see the image in negative, so content consumption will be primarily a one-person affair. Audio is another story: the Aspire S3 has two 3DSonic speakers, one on either side, with the experience improved thanks to Dolby Home Theater v4 audio enhancement. The quality of sound produced by the slim ultrabook is unexpectedly robust and clear.

Also notable is the keyboard. The chiclet-style keys look similar to the square-tiled keys of the MacBook Air, and they also manage to impart the same smooth typing and shallow keystrokes. The quality is quite good, but you won't find a backlight on the Aspire S3 like you would on the MacBook Air. The touchpad may not be enormous, but it's large enough for all of the gestures available on the glass-topped trackpad. The right and left mouse buttons are integrated into the trackpad surface as well, and clicking is as simple as pressing on the face of the mouse, or in either lower corner. It's the closest I've seen to replicating the Apple clickpad experience on a Windows laptop, and it managed to pull it off pretty well. As testing wore on, however, I did notice that multitouch controls, like zoom and scroll, didn't always register properly.

Features
That ultrathin profile is achieved, in part, by offering few features. Along the back edge of the Acer Aspire S3, you'll find two USB 2.0 ports and an HDMI port. On the right edge of the laptop you'll find a media card reader (SD, MMC), and on the left, you'll find a headset jack, combining a headphone and microphone jack in one. Internally, the Aspire S3 is equipped with 802.11n Wi-Fi and Bluetooth 4.0 wireless options, and a 1.3-megapixel webcam atop the 13-inch screen. But what don't you get? To maintain that greyhound-thin profile, Acer has jettisoned common connections like a VGA port, Ethernet, and optical drive, which is par for the course in all the Ultrabooks we've seen so far. You also won't enjoy the faster speeds of USB 3.0, which you will find on the Zenbook UX31, and the even faster speeds of Thunderbolt technology, which is only found on Apple products right now.

Though several competitors have opted to use nothing but solid-state flash memory in their Ultrabooks, Acer has chosen a mechanical hard drive, which offers greater capacity for a lower price. The 320GB 5,400rpm spinning hard drive offers far more storage than the 128GB solid-state drives (SSD) found standard in the MacBook Air and Asus Zenbook UX31. On the flipside, the spinning drive is more prone to damage from bumps and falls, and doesn't offer the same speed and responsiveness that an SSD can provide. Acer addresses the responsiveness problem with an additional 20GB of flash memory, allowing the Aspire S3 to have the same speedy boot and wake times offered by an SSD. To protect the hard drive from physical damage, the Aspire S3 is equipped with an accelerometer that activates drive protection whenever the laptop is moved.

Acer includes a lot of pre-installed hardware on the Aspire S3. Some of it is useful, like Clear.fi, Acer's wireless media sharing solution, Microsoft Office Starter 2010, and a 60-day trial of McAfee Internet Security. Others are just bloatware, like a New York Times reader, the Barnes & Noble Nook App, Blio e-reader, Acer Games, and dedicated links to eBay and Netflix. You'll also find a number of Acer utilities for everything from tweaking the sleep settings to using the webcam.

Performance
The Aspire S3 runs on a dual-core Intel Core i5-2467M 1.6 GHz processor. If that processor model sounds familiar, it's because it's the same ultra-low voltage CPU found in the 11-inch MacBook Air, as well as the new crop of Ultrabooks, including the Asus Zenbook UX21 ($999 direct, not yet reviewed) and Lenovo U300. It's energy efficient and less prone to overheating, making it the ideal CULV processor for the thin, light, long-lasting ultrabook. Though bolstered with 4GB of RAM, PCMark 7 scores showed that it's not quite a match for the Intel Core i5-2557M CPU found in the 13-inch MacBook Air. In PCMark 7, our day-to-day performance test, the Aspire S3 scored 1,899 points, significantly behind the 3,186 scored by the MacBook. In tests like CineBench R11.5 (1.93) and Photoshop CS5 (5:37), the Aspire S3 performed well. Although it fell behind the Apple MacBook Air, it met or even beat the scores of the Samsung Series 9 (1.36 in Cinebench; 5:53 in CS5) and Toshiba R835-P50X (2.04 in Cinebench; 5:36 in CS5). Only time and lab testing will tell us how the Aspire S3 stacks up against the incoming ultrabook competitors.

With only the integrated graphics offered by the Core i5 processor, the Aspire S3 wasn't equipped for graphics-intensive activity like gaming, but that's no surprise. In 3DMark06, the Aspire S3 scored 3,530 points at 1,024-by-768 resolution settings and 1,791 at its native 1,366 by 768; this beats out the Samsung Series 9 (2,441 at medium) but not the MacBook Air (4,781 at medium) or Toshiba Portege (4,550 at medium). The Aspire S3 scored 16.3 frames per second (fps) in Crysis and 15.4 fps in Lost Planet 2 at medium resolution settings. Neither test could run at full resolution and detail, indicating that you'll be relegated to very basic gaming on the ultrabook.

Acer estimates that you'll get as much as 7 hours of continuous use out of the Aspire S3's internal sealed battery, but our testing clocked it at 5 hours 20 minutes in MobileMark 2007. That's not too shabby for a small 3-cell, 36Wh battery. By comparison, the MacBook Air lasted 5:46 with a 50Wh battery, the Samsung Series 9 lasted 6:04 with a similar battery. The Toshiba Portege R835-P50X lasted 9:26, albeit with a much larger 66Wh battery. Like the MacBook Air and the Samsung Series 9, the Aspire S3 sheds some girth by sealing the battery inside the chassis, making it inaccessible to the regular user. This looks to be the rule rather than the exception, so be aware that swapping out batteries for longer life won't be a viable option for this or any other ultrabook. Acer also claims that the Aspire S3 provides 50 days of standby time?20 days more than the 30 days claim for the MacBook Air and certainly more than the 14 days being offered by Asus UX21 and UX31. We couldn't test this claim overnight, but you should feel confident that you can leave the laptop in standby mode for a while.

The Acer Aspire S3 is the first ultrabook we've seen, so it's a bit early to tell where it fits within the overall category. It has some definite high points, like a super thin profile, larger storage capacity, and affordability that is currently unmatched. But it also rang hollow on a few important notes: the build quality simply feels cheap, despite the magnesium lid, and the screen doesn't offer the same resolution offered by competitors. At the moment, the MacBook Air 13-inch or the Editors' Choice Toshiba Portege R835-P50X are stronger choices, but the ultrabook landscape will be changing rapidly, so stay tuned.

Reversing sickle cell anemia by turning on fetal hemoglobin

Friday, October 14, 2011

Not long after birth, human babies transition from producing blood containing oxygen-rich fetal hemoglobin to blood bearing the adult hemoglobin protein. For children with sickle cell disease, the transition from the fetal to adult form of hemoglobin ? the oxygen-carrying protein in blood -- marks the onset of anemia and painful symptoms of the disorder.

Now, new research led by Howard Hughes Medical Institute (HHMI) investigator Stuart H. Orkin of Children's Hospital Boston, Dana Farber Cancer Institute, and Harvard Medical School shows that silencing a protein known as BCL11A can reactivate fetal hemoglobin production in adult mice and effectively reverses sickle cell disease. The new finding, reported October 13, 2011, in Science Express, reveals that BCL11A is one of the primary factors involved in turning off fetal hemoglobin production.

"I think we've demonstrated that a single protein in the cells is a target that, if interfered with, would provide enough fetal hemoglobin to make patients better," says Orkin. "It's been hypothesized for three decades that fetal hemoglobin could be turned on once we understood the mechanism of hemoglobin switching, and this is the first evidence of a target to do that."

BCL11A is likely one of a suite of up to a dozen factors that influence fetal hemoglobin levels, Orkin says, but the new study provides hard evidence that it is one of the key players in regulating the production of fetal hemoglobin. BCL11A works as a repressor by binding to DNA and regulating gene expression.

Sickle cell anemia is a genetic disease that affects hemoglobin production. It is estimated that as many as 100,000 people in the United States and many more in other parts of the world, Africa in particular, have the disease. A single nucleotide change in the hemoglobin gene causes an amino acid substitution in the hemoglobin protein from glutamic acid to valine. The resulting proteins stick together to form long fibers and cause the development of irregular, crescent-shaped red blood cells.

It is no secret to scientists or clinicians that elevating fetal hemoglobin in human sickle cell patients can help alleviate the pain-fraught episodes of fatigue and abdominal and bone pain that are hallmarks of the condition. Though a few drugs have been found that can increase fetal hemoglobin, biomedical researchers have spent decades trolling for the basic molecular mechanisms that control the shift from fetal to adult hemoglobin. Recent genome-wide association studies helped narrow the search to a few genes and now, in a critical "proof of principle" test in transgenic mice, the team led by Orkin identified the critical role of BCL11A in tamping down the production of fetal hemoglobin.

Fetal hemoglobin differs from the adult form of the protein in its affinity for oxygen. Production of fetal hemoglobin begins about two months into gestation and helps deliver oxygen from the mother's bloodstream to the developing fetus. By about 3-6 months after birth, fetal hemoglobin is almost completely replaced by adult hemoglobin. The timing, notes Orkin, explains why sickle cell patients don't experience symptoms of the disease until several months after birth.

Drug therapy with the agent hydroxyurea helps ramp up fetal hemoglobin in some patients and reduces the number of painful episodes characteristic of sickle cell. But the drug is not uniformly effective, has several side effects and its mode of action is unknown.

Orkin notes that sickle cell was the first congenital disease for which scientists determined the single amino acid change in hemoglobin that sparks the condition. That work was done 60 years ago, he says, but that knowledge has never informed therapy for the disease.

Elevating the amount of fetal hemoglobin, says Orkin, emerged as a desirable strategy for treating sickle cell as clinicians and researchers noted long ago that levels of fetal hemoglobin naturally vary among individuals and that those sickle cell patients who express more of the fetal form of the protein experience fewer episodes of pain. "The more fetal hemoglobin you have, the better," says Orkin, noting that elevating levels of the fetal protein seems to have no toxic side effects. "The cell doesn't care if it's producing fetal hemoglobin or not."

The new study was done through genetic manipulation of a mouse model of sickle cell disease, demonstrating that in the future, gene therapy may be feasible. Knowing the target protein also means the search for new drugs to govern the production of fetal hemoglobin can shift to a higher gear. Finally, the new work holds promise for devising new treatments for a other congenital blood disorders known as thalassemias, which are also caused by an underproduction of adult hemoglobin.

Now that this key switch has been identified, Orkin asserts, the chances of powerful new therapies for sickle cell and other hemoglobin disorders will become more evident: "For the last 20 years we've been shooting arrows in the dark in hopes of hitting the target. Now we can see the target and it is a meaningful one."

Romney's rise challenges tea party's clout in GOP (AP)

WASHINGTON ? Mitt Romney's early success in the Republican presidential race is challenging the tea party's clout. Will it continue to pull the GOP sharply right? Will it slowly fade? Or merge with mainstream Republican elements in a nod to pragmatism, something it's hardly known for?

On the surface, Romney's strength seems at odds with the tea party's fiery success in ousting Republicans seen as compromisers, and in making the House GOP caucus more ideological, even when its leaders plead for flexibility.

Romney defends the government's 2008 bank bailouts, plus the mandated health insurance he initiated as Massachusetts governor. He says he can work with "good Democrats." Although he later changed, Romney once supported abortion rights, gun control and gay rights.

These positions run counter to the beliefs and goals of many tea party activists scattered throughout the country. Yet Romney is faring better in polls, fundraising and debates than are contenders with stronger tea party credentials, including Michele Bachmann, Rick Santorum and Rick Perry.

Several Republican strategists, and even some tea party leaders, say they aren't surprised or alarmed. Their overarching goal is to defeat President Barack Obama next year, they say, and if Romney is best-positioned to do that, they'll endure his shortcomings.

"The perception that tea partyers are ideological purists is wrong," said Sal Russo, a long-time Republican strategist in California and a leader of the Tea Party Express. "We are a broad-based movement," he said, "and we are looking to win in 2012."

Danny Diaz, a Washington-based Republican strategist unaligned with any presidential candidates, agrees.

"The tea party movement is an anti-Washington movement," he said. While Perry and Herman Cain might make a more dynamic claim to that mantle, he said, Romney has never lived in Washington, and tea party activists won't rule him out.

"Many of them are pragmatists," Diaz said. They desperately want to oust Obama, he said, and "they need a candidate that's electable."

A CBS-New York Times poll found that tea partyers are more satisfied with the GOP presidential field than are Republicans in general. Cain was the top choice among tea party activists, with Romney second.

Some campaign veterans see bigger problems ahead for Romney.

Polls of Republicans show Romney holding steady at about 25 percent, while Bachmann, Perry and Cain take turns making surges. "That tells me that 75 percent of the primary voters would really rather have someone else," said GOP lobbyist and consultant Mike McKenna.

Many tea party activists have little or no loyalty to the Republican Party, and McKenna predicts big problems next year if they feel their conservative values were sacrificed for political expediency. "Romney would cause enormous numbers of tea party-type voters to simply not show on game day," he said.

The chief question, he said, "is whether one candidate will be able to aggregate the anti-Romney Republicans before it is too late." Perry seems the likeliest choice, McKenna said, "but the clock is ticking."

Jenny Beth Martin of Atlanta, who is active with Tea Party Patriots, said several groups are having informal talks about whether they should try to coalesce behind an alternative to Romney. Tea partyers cherish their independence, she said, and "over the next eight to 10 weeks, it'll be interesting to see how it all shapes up."

Conservative commentator Rush Limbaugh repeatedly criticized Romney on his radio show last week. "Romney is not a conservative," he said. "The Republican base doesn't want Romney."

For now, Romney seems willing to run some risks, hoping to attract independent voters who will be crucial in the 2012 general election.

In last week's debate in New Hampshire, Romney defended President George W. Bush's 2008 decision to spend billions to rescue banks teetering on collapse, partly because of disastrous home loans. The action was meant not just to save banks, Romney said, "but to keep the entire currency of the country worth something and to keep all the banks from closing and to make sure we didn't all lose our jobs."

Many conservatives despise the bailout, known as TARP, for Troubled Asset Relief Program. In one of their first political victories, tea party activists in Utah chanted "TARP, TARP" at then-Sen. Robert Bennett as they bounced him from the GOP ticket at a 2010 party convention. Bennett, a three-term senator with solid conservative credentials, had voted for the program.

Nonetheless, there was little commentary about Romney's TARP comments after Tuesday's debate, which focused largely on Cain's tax overhaul plan.

It may take hard-hitting TV ads to drive a bigger wedge between Romney and tea partyers, something the well-financed Perry might try soon. Such ads could go into detail, with heavy repetition, about Romney's Massachusetts health care plan, which was a partial model for Obama's 2010 federal overhaul.

Virginia-based Republican strategist Chris LaCivita says the tea party's deliberately decentralized nature makes it ill-suited to play a big role in presidential politics.

"The tea party's strength was always a state-driven or congressional district-driven level," he said. It can continue to influence targeted contests that draw comparatively small turnouts, such as the Utah GOP convention that drummed Bennett out of the party.

Moreover, LaCivita said, the tea party might choke on its own success. If it appears more like the Republican mainstream, he said, it's because tea partyers have shifted that mainstream to the right.

Largely because of their clout in the 2010 elections, LaCivita said, these activists have "changed the conversation, not only among Republicans, but everybody in Washington. Who'd have thought the Democrats would be leading with spending cuts" in deficit-reduction talks?

Those ongoing negotiations, however, could renew tensions between tea party-affiliated House Republicans and the party's more established leaders, including Speaker John Boehner. If presidential candidates are pressed for their views, Romney might find it difficult to keep appealing to independents without antagonizing tea partyers.

The Republican Party "still hasn't resolved all of its ideological internal conflicts," said John Feehery, a top aide to then-Speaker Dennis Hastert, R-Ill. "But they have agreed that they don't like Obama," he said.

Their level of intensity may determine whether Romney can keep prospering against rivals who boast stronger tea party ties.

Finance And Business | Beginner Forex Currency Trading: What is it ...

For a beginner forex currency trading may seem to be a whole new world but in fact the basics are quite easy to learn. Getting used to the terminology used and understanding the basics of Forex trading is what you need to get started. Of course, a trading robot like the Forex Megadroid Robot could help you get started too, but more on that later.

Most people?s ambition in Forex trading is to earn big bucks in a short time! You may be surprised to learn that this is a possibility, due to the quick fluctuations that occur in the market everyday. This means of course that it is risky and there is also a chance of losing a lot, just like most things in life that have the potential of big returns.

Most of us have experienced the Forex market in a small way, when exchanging money for a trip abroad, and know the rates do change. For example you may change $100 into another currency you are planning to travel to, and then find that you do not need it and change it back. During this time the exchange rate will have no doubt changed, and you will get back a slightly different amount.

The idea of trading Forex is to buy and sell currency at a profit every time, but instead of changing money at the bank they use a broker. Online trading has grown immensely in recent years. In many ways it is not so different from stock trading. There is the same potential to trade in margins where a small balance held by your broker can control much larger deals.

The major difference forex has over the stock market, is that it is entirely possible to trade outside of your own country. You can trade any two currencies regardless of where you live. This gives us an extremely international trading market. Due to the different time zones in all the major currencies countires, forex trading takes place 24 hours a day throughout the globe.

A 3 letter code is assigned to each currency: USD for the US dollar, GBP for the British pound, EUR for the Euro, JPY for the Japanese Yen, CHF for the Swiss franc, CAD for the Canadian dollar, AUD for the Australian dollar etc. The common format for showing 2 currencies exchange rate is: USD/CHF 1.14. This means that to buy one US dollar you will need 1.14 Swiss francs.

If you want to start out in forex trading you will need to look for a broker or investment management company that you trust. It is worth shopping around and checking online forums for recommendations. Check out how long the company has been in business and what your rights and liabilities will be. Always check the Terms and Conditions.

you may want to employ the use of a trading robot, such as the Forex Megadroid Download. These robots are complex pieces of trading software, that are able to carry out your trading on your behalf. There is usually a demo option so that you can test out the whole system for a while before you let it trade with real money. There are many forex robots on the market and most of them come with full instructions for beginner forex currency trading.

Fountains of Life Found at the Bottom of the Dead Sea

For years, ripples at the surface of the Dead Sea hinted there was something mysterious going on beneath its salt-laden waters. But in a lake where accidentally swallowing the water while diving could lead to near-instant asphyxiation, no one was in a hurry to find out what it might be.

This year, some intrepid divers changed that, stumbling onto a geological and biological treasure and capturing it on video. We?ll get to that in just a moment.

Don't drink the water: the Dead Sea. Creative Commons xta11. Click Image for License and link.

This is the Dead Sea. As you can see, it appears quite dead. There are no plants, fish, or any other visible life in the sea. Its salt concentration is a staggering 33.7%, 8.6 times saltier than ocean water, which is only about 3.5% salt. The stones at the water?s edge encrusted in salt are a good clue in that department. As a result, the Sea is famous for its body buoyancy properties, as people who take an exploratory dip generally find themselves riding high on its waters.

The Dead Sea is also the lowest point on earth, and getting lower every year, as water that would ordinarily fill it by flowing in from the Jordan River has been diverted to quench the thirst of Israel, Jordan, and Palestine. Every year, the lake drops over a meter per year. If this goes on long enough, the Sea could face Owens Lake?s and the Aral Sea?s fate: becoming a wind-swept salt flat. Yet, for now, life goes on.

Biologists have known since the 1930s the lake is ?not dead yet?. Instead, it?s full of microbes that get along quite happily in the salty soup, for it keeps out competitors that would take over in a more hospital aqueous environment. In general, the water contains 1,000 to 10,000 archaea* per ml, a much lower concentration of life than in seawater, but quite respectable, all in all, for a place where one molecule in three is not water. Occasionally, when conditions are right, the sea blooms red with life. This happened in 1980 and 1992.

In any case, divers from Israel and Germany finally braved the waters this year to see what might have been causing the aforementioned? concentric-ringed ripples observed near shore. They were not disappointed. This is what they found:

These are freshwater springs, jetting into the bottom of the Dead Sea from inside craters. Found as deep as 100 feet from the surface, the springs lie at the base of craters as large as 50 feet wide and 65 feet deep.? As can be seen, a variety of interesting geological formations surround them.

The springs roil the waters they flow into in a phantasmal slipstream. Starting at about 2:00, you can see it coiling and mixing like it?s hundreds of degrees hotter or more sugary than the surrounding water. But no, it?s just that much less salty (and dense). (There?s a famous scene in the ?Caves? episode of Planet Earth that vividly illustrates salinity gradients (haloclines) in the cenotes of Mexico too ? go track down a copy if you can).

What makes this place biologically amazing was the life they found near the plumes.

A nice article on the discovery at National Geographic notes:

The top of the springs? rocks are covered with green biofilms, which use both sunlight and sulfide?naturally occurring chemicals from the springs?to survive. Exclusively sulfide-eating bacteria coat the bottoms of the rocks in a white biofilm.

Bacterial mats or biofilms have never been found in the Dead Sea before. You can see the films of green photosynthetic bacteria on top of a rock and a film of white sulfide-oxidizing bacteria underneath it in the very last scene of the movie. Go have a peek.

Not only have the organisms evolved in such a harsh environment, Ionescu speculates that the bacteria can somehow cope with sudden fluxes in fresh water and saltwater that naturally occur as water currents shift around the springs.

Ionescu further pointed out that all known hard-core halophiles, or salt-loving microbes, die if you put them in freshwater, and vice versa. How these microbes are able to withstand what must be wicked shifts in salinity on an ongoing basis is anyone?s guess. This reminds me of the creatures at deep sea vents that must withstand massive fluctuations in temperature as ventwater hundreds of degrees hotter than the surrounding seawater shifts back and forth. I?ll say it along with Jeff Goldblum once more: ?Life finds a way.?

Whatever they are ? and scientists are planning to go back to find out more ? they are not like the microbes found in the rest of the sea nor like the organisms that cause the sea to occasionally bloom red. And they are very diverse ? much more so than their halophilic neighbors.

The article also notes that the Dead Sea?s waters are particularly caustic and difficult for divers, which, as a new diver myself, I found particularly interesting/horrifying. In addition to having to weight yourself down incredibly ? on the order of 90 pounds; when I dove in Hawaii last year, I used about 12 pounds ? Dead Sea water is not something you want coming into contact with your face. Ever.

Divers will also need to wear full face masks to protect their eyes and mouths. That?s because accidentally swallowing Dead Sea salt water would cause the larynx to inflate, resulting in immediate choking and suffocation.

Oh good.

Likewise, the intensely salty water would instantly burn and likely blind the eyes?both reasons why Dead Sea swimmers rarely fully submerge their bodies, Ionescu noted.

I well recall practicing losing, replacing, and clearing my mask of water at depth when I was getting certified. I guess in the Dead Sea, that?s more of the nuclear option in case of leak or ?wardrobe malfunction?.

For more information on the springs (which have not be formally published in a journal yet), see the scientists? press releases here and here.

Aspergers Syndrome ? General Information | Infopadres: Share Your ...

Aspergers Syndrome is a kind of Autism, however, the symptoms are normally a lot milder and fewer distressing to these folks round them. However, it is nonetheless a severe condition which affects 1-2 individuals in 2000, of which, more are typically boys than girls.

Aspergers Syndrome wasn?t widely known by mother and father and professionals as not too long ago as within the 1990?s. Autism itself was first diagnosed in 1943.

Regardless of what could possibly be seen as a major downside for the victims of Aspergers Syndrome, many people with this situation lead very successful and productive lives.

Autism is a neurological disorder. No one is aware of precisely what causes it although there does seem to be a high degree of evidence which suggests that it may be genetic. In lots of cases, the place one little one in a household has autism or Aspergers Syndrome, there is a significant chance that any other youngsters can even have this situation either to a lesser or greater degree.

It is attainable that there are other factors which may trigger this condition either before throughout or after the delivery of a child. At this current time, we do not know the answers to this query although hopefully after much research, the reply will be found.

There isn?t a simple check to diagnose Aspergers Syndrome or Autism, the analysis is finished by taking a developmental history and commentary of the patient.

There is no remedy for both Aspergers Syndrome or Autism either. However, with loads of laborious work, many victims of Aspergers dwell strange lives with few difficulties.

Aspergers symptoms embody
? Deficiency in social abilities
? Problem with accepting adjustments to their atmosphere
? They may be very pre-occupied with a particular matter and research it and speak about it incessantly, turning into very proficient in it.
? Discover it difficult to read non verbal communication alerts and have a tendency to have poor body space i.e. they may invade different peoples area unknowingly.

Despite these signs, many sufferers from Aspergers live regular lives and in some instances, in all probability attributable to their obsession with a specific matter, could grow to be very successful.

Kabul hands Pakistan evidence on peace envoy killing (Reuters)

KABUL (Reuters) ? Afghanistan's intelligence agency said on Saturday that it had handed Pakistan evidence that the Taliban's leadership plotted the recent assassination of ex-president and government peace envoy Burhanuddin Rabbani on Pakistani soil.

The interior minister, giving testimony in parliament, also said that a master-mind of the plot -- Hameedullah Akhondzada -- had been arrested. The minister said Pakistan's spy agency, the Directorate of Inter-Services Intelligence (ISI), played a role in the killing.

Rabbani, who was head of the High Peace Council charged with trying to reach a negotiated settlement to the war, was killed at his Kabul home by a suicide bomber claiming to be carrying a message of peace from the Taliban leadership.

"Without any doubt Pakistan's ISI hand has been involved," Interior Minister Bismillah Mohammadi told lawmakers on Saturday, while discussing Rabbani's killing.

"We have detained Hameedullah Akhondzada who confessed that it was nothing but a plot," he added.

Mohammadi said a fact-finding mission was leaving for Pakistan on Saturday to investigate further, and Islamabad had been given a list of those involved.

A spokeswoman for Pakistan's Foreign Office, Tehmina Janjua, said Pakistan had not received any information although Prime Minister Yusuf Raza Gilani had conveyed to Afghan President Hamid Karzai an offer of cooperation in the investigation.

"Pakistan's offer to investigate stands. As yet, no dossier has been received," she said.

Akhondzada has been named by the Afghanistan's National Directorate of Security (NDS) but it has given no details of his identity. Acting NDS chief Rahmatullah Nabeel also said that Akhondzada had been detained, but gave no details.

Rabbani was the most prominent surviving leader of the ethnic Tajik-dominated Northern Alliance of fighters and politicians and his killing was seen as a heavy blow to hopes of peace talks and has brought fears of worsening ethnic rifts among Afghans fighting the Taliban-led insurgency.

"PLOTTED IN QUETTA"

The NDS spokesman, at a separate news conference said that the mid-September suicide bombing that killed Rabbani, the government's top peace negotiator, was plotted in an upmarket suburb of the Pakistani city of Quetta.

The Taliban leadership council is known as the Quetta Shura, and is believed to be based in that city, although the insurgent group says it operates only from Afghanistan. Pakistan denies the existence of any Taliban shura in Quetta.

"A confession from those we detained in regard to Rabbani's assassination shows a direct involvement of the Quetta Shura," NDS spokesman Lutfullah Mashal said, adding that one of those arrested was a key player in the plot to kill Rabbani.

"(He) provided evidence and documents which we have submitted to the Pakistan Embassy. Based on mutual cooperation and diplomatic ties with Afghanistan, Pakistan is obliged to take action," he told a news conference in the Afghan capital.

Rabbani's assassination was plotted in Quetta's Satellite Town, an expensive area home to many officials and the city's elite, Mashal added.

He said a commission had been set up to investigate the killing, and further details would be given soon.

Hours after Rabbani was killed, a spokesman for the Taliban claimed responsibility for his death when talking to a Reuters reporter in Pakistan from an undisclosed location.

However, the spokesman later issued statements denying that he had made a claim of responsibility and said the Taliban were not willing to comment on Rabbani's assassination.

Error and Trial: Italian Scientists Face Prison as Earthquake Manslaughter Hearing Resumes This Weekend

News | More Science

Six renowned geophysicists are on the hot seat, but is it for failing to predict an earthquake or failing to clearly communicate their findings?

By Larry Greenemeier ?| September 30, 2011?|

AT FAULT: A government building severely damaged by the April 2009 magnitude 6.3 earthquake in L'Aquila, Italy. Image: Courtesy of TheWiz83, via Wikimedia Commons

Did scientists and public officials encourage residents of L'Aquila to let their guard down prior to a tragic April 2009 earthquake that killed 309 people in that central Italian city? That is what an Italian court will consider Saturday as it resumes an unprecedented manslaughter trial of six Italian geophysicists and one former government official.

The defendants were part of Italy's National Commission for Forecasting and Predicting Great Risks that held a special meeting in L'Aquila the week before the earthquake to address concerns over recent seismic activity but, according to prosecutors, provided "incomplete, imprecise and contradictory information." As a result of this information, communicated largely via a press interviews before and after the meeting, many L'Aquila residents felt no need to abandon their homes, prosecutors allege. The magnitude 6.3 earthquake ended up leveling about 20,000 buildings in and around L'Aquila.

Scientists, more likely to serve as expert witnesses than defendants in court, are still coming to terms with the legal problems facing their Italian colleagues. If convicted, the defendants are looking at up to 15-year prison terms in addition to a civil suit seeking more than $30 million in damages.

"When they were indicted in June 2010, I was surprised," says Thomas Jordan, director of the Southern California Earthquake Center (SCEC) and professor of earth sciences at the University of Southern California, where SCEC is headquartered. "When that judicial review was ordered to trial, I was surprised. So I guess I'm getting used to the fact that this thing has legs." Now, he adds, "it looks to me based on what I have heard that there are liable to be some guilty verdicts coming out of this phase of the trial."

A debate has risen as to whether seismology itself is on trial. Whereas prosecutors argue that it is not, an open letter sent last year to Italy's president, Giorgio Napolitano, and signed by more than 5,000 members of the scientific community claims that the defendants are being persecuted for failing to do the impossible?predict the time, place and magnitude of an earthquake.

Such protestations are "a little off base in that they don't really get at the main issues of the trial," Jordan says. Regardless, the outcome of this case is likely to send tremors throughout the scientific community, particularly among disciplines such as seismology that seek to better understand and forecast natural disasters. "The public is in some ways becoming more demanding," Jordan says, adding that they want fast access to accurate scientific information gathered in as transparent a manner as possible.

Look no further than last year's Gulf oil spill for evidence of this. "People were really very angry, feeling that they were in some sense being deceived by BP and to some degree by the government for not providing information about how bad that disaster really was," Jordan says.

Whereas answers to tough scientific questions such as when and where a major temblor will strike are elusive today, it is not for lack of trying. Jordan chaired the International Commission on Earthquake Forecasting for Civil Protection formed by the Italian government in the aftermath of L'Aquila to assess the scientific knowledge of earthquake predictability and provide guidelines for effectively gathering, updating and disseminating information to the public. The commission, which submitted its findings in May, recommended several measures, including real-time, interagency sharing of seismic data and the development of new earthquake forecasting methods.

The commission also cited efforts already underway to test earthquake forecasting, in particular the Collaboratory for the Study of Earthquake Predictability (CSEP). CSEP is a network of collaborating laboratories set up near active fault systems in the western U.S. as well as Italy, Japan, New Zealand and elsewhere to perform earthquake prediction experiments and determine how such experiments should be conducted and evaluated. "This type of forecasting apparatus is prospective, meaning the forecasts are fixed and blind and the performance is tested in a rigorous way," Jordan says. "We started the first testing in California in 2007. Italy began testing about five months after the L'Aquila event." (A team of researchers published the results of California's Regional Earthquake Likelihood Models test of quake forecasts last month in Proceedings of the National Academy of Sciences.) (pdf)

None of this assures earthquake forecasting improvements in the near future, and some scientists worry that public expectations will outpace scientific capabilities. "One of the issues in L'Aquila was how much attention should have been paid to the foreshocks leading up to the earthquake," says Robert Yeats, a professor emeritus in geoscience at Oregon State University in Corvallis and co-author of the article "Hidden Earthquakes" in the June 1989 issue of Scientific American. There are plenty of examples of foreshocks, including those near the Hanford Nuclear Reservation in Washington State that never lead to temblors, Yeats says.

One of the best remedies is for scientists, and those speaking on their behalf, to choose their words more carefully, Yeats adds. One of the most egregious violations of this tip came when Bernardo De Bernardinis, then vice director of the Department of Civil Protection, spoke at a pre-quake press conference to discuss the commission's meeting. De Bernardinis reportedly downplayed the danger of an imminent earthquake. When a reporter asked whether residents should then relax with a glass of wine, he is quoted as saying "Absolutely, absolutely a Montepulciano doc," referring to a type of red wine. De Bernardinis's lawyers claim he was making a joke, but prosecutors have seized on this statement nonetheless.

Still, scientists are a hearty lot and not easily silenced, Jordan says. "What is important is that we put together systems for gathering and transmitting that information to the public that are better," he adds. "I think the main impact of L'Aquila will be to underline the need for this kind of information transmission and public notification, raising public awareness."

Canada's Arctic ice shelves breaking up fast

TORONTO?? Canada in just six years has lost nearly 50 percent of the massive ice shelf area that holds back glacial ice from melting into the ocean, scientists report.

Two of Canada's biggest ice shelves diminished significantly this summer, one nearly disappearing altogether. The two are among six that make up Canada's biggest shelves, all located on Ellesmere Island.

The loss is important as a marker of global warming, returning the Canadian Arctic to conditions that date back thousands of years, scientists say.

Floating icebergs that have broken free as a result pose a risk to offshore oil facilities and potentially to shipping lanes. The breaking apart of the ice shelves also reduces the environment that supports microbial life and changes the look of Canada's coastline.

Luke Copland, an associate geography professor at the University of Ottawa, said the Serson Ice Shelf shrank from 79 square miles to two remnant sections five years ago, and was further diminished this past summer.

Serson went from a 16-square-mile floating glacier tongue to 10 square miles, and the second section from 13 square miles to 2 square miles.

In addition, Ward Hunt Ice Shelf's central area disintegrated into drifting ice masses last summer, leaving two separate ice shelves measuring 88 and 29 square miles respectively, reduced from 132 square miles the previous year.

"It has dramatically broken apart in two separate areas and there's nothing in between now but water," said Copland.

Copland said those two losses are significant, especially since the Ward Hunt Ice Shelf has always been the biggest, the farthest north and the one scientists thought might have been the most stable.

"Since the end of July, pieces equaling one and a half times the size of Manhattan Island have broken off," Copland said in a statement. Copland uses satellite imagery and has conducted field work in the Arctic every May for the past five years.

Co-researcher Derek Mueller, an assistant professor at Carleton University, said the loss this past summer equals up to three billion tons of ice.

"This is our coastline changing," Mueller stated. "These unique and massive geographical features that we consider to be part of the map of Canada are disappearing and they won?t come back."

"Recent (ice shelf) loss has been very rapid, and goes hand-in-hand with the rapid sea ice decline we have seen in this decade and the increasing warmth and extensive melt in the Arctic regions," said Ted Scambos, lead scientist at the National Snow and Ice Data Center at the University of Colorado, remarking on the research.

Copland said their findings have not yet been peer reviewed since the research is new, but a number of scientists contacted by The Associated Press reviewed the findings, agreeing the loss in volume of ice shelves is significant.

Scambos said the loss of the Arctic shelves is significant because they are old and their rapid loss underscores the severity of the warming trend scientists see now relative to past fluctuations such as the Medieval Warm Period.

Ice shelves are much thicker than sea ice, which is typically less than a few feet thick and survives up to several years.

Canada has the most extensive ice shelves in the Arctic along the northern coast of Ellesmere Island. These floating ice masses are typically 130 feet thick (equivalent to a 10-story building), but can be as much as 330 feet thick. They thickened over time via snow and sea ice accumulation, along with glacier inflow in certain places.

The northern coast of Ellesmere Island contains the last remaining ice shelves in Canada, with an estimated area of 402 square miles, said Mueller.

Between 1906 and 1982, there has been a 90 percent reduction in the areal extent of ice shelves along the entire coastline, according to data published by W.F. Vincent at Quebec's Laval University. The former extensive "Ellesmere Island Ice Sheet" was reduced to six smaller, separate ice shelves: Serson, Petersen, Milne, Ayles, Ward Hunt and Markham.

In 2005, the Ayles Ice Shelf whittled almost completely away, as did the Markham Ice Shelf in 2008 and the Serson this year.

"The impact is significant and yet only a piece of the ongoing and accelerating response to warming of the Arctic," said Robert Bindschadler, emeritus scientist at the Hydrospheric and Biospheric Sciences Laboratory at the NASA Goddard Space Flight Center in Maryland.

Bindschadler said the loss is an indication of another threshold being passed, as well as the likely acceleration of buttressed glaciers able to flow faster into the ocean, which accelerates their contribution to global sea level.

Copland said mean winter temperatures have risen by about 1.8 degrees Fahrenheit per decade for the past five to six decades on northern Ellesmere Island.
