There's nothing quite like a total eclipse (of the heart), but an annular eclipse is a close second. Especially if you're into rings of fire. And after you watch this incredible video from one that took place in Pilbara, Australia last weekend, you'll be a fan.

Cutting-edge bacteria research leads to more effective treatment of complex infections
Wednesday, May 15, 2013Bacteria are life forms, which, like all other life forms, struggle for the best living conditions for themselves. Therefore they will try to avoid getting attacked by the human immune system, and therefore they have developed various ways to protect themselves from the human immune system. When safe from the immune system, they can focus on breeding and multiplying, and if they become numerous enough, the human body will experience their presence as an infection. Some bacteria are relatively harmless, while others are fatal. The bacteria avoid being attacked by the human immune system by forming a biofilm - a surface to protect them against the immune system.
"The biofilm contributes to bacterial resistance, and that can cause severe, persistent infections around heart valve implants and in lungs and the urinary tract," explains postdoc. Mikkel Girke J?rgensen from the Department of Biochemistry and Molecular Biology at the University of Southern Denmark. Together with professor Poul Valentin-Hansen from the same institution and scientists from American Eunice Kennedy Shriver National Institute of Child Health and Human Development, Bethesda, and Georgetown University Medical Center, Washington DC, he stands behind the new discovery.
The researchers now understand the underlying regulatory mechanisms behind the formation of biofilms. The mechanism involves small RNA molecules, which can affect bacterial gene expression and thus the decision of whether to form biofilm or not.
Bacteria can move by using their so-called flagella to swim with. When they need to form biofilms, they "turn off" the flagella, stop moving and start to form a biofilm.
"We have now established what decides whether they swim or not - and that determines whether they form biofilms or not," explains Mikkel Girke J?rgensen and continues:
"Prospects for the pharmaceutical industry are huge. This increased understanding of biofilm formation may be the first step in creating new ways to treat complicated infections in the future. "

May 15, 2013 ? Statins, the most widely prescribed drugs worldwide, are often suggested to lower cholesterol and prevent heart disease in individuals with obesity, diabetes and metabolic syndrome, which is a combination of medical disorders including excess body fat and/or high levels of blood pressure, blood sugar and/or cholesterol. However, University of Missouri researchers found that simvastatin, a generic type of statin previously sold under the brand name "Zocor," hindered the positive effects of exercise for obese and overweight adults.
"Fitness has proven to be the most significant predictor of longevity and health because it protects people from a variety of chronic diseases," said John Thyfault, an associate professor of nutrition and exercise physiology at MU. "Daily physical activity is needed to maintain or improve fitness, and thus improve health outcomes. However, if patients start exercising and taking statins at the same time, it seems that statins block the ability of exercise to improve their fitness levels."
Thyfault says many cardiologists want to prescribe statins to all patients over a certain age regardless of whether they have metabolic syndrome; the drugs also are recommended for people with Type 2 diabetes. He recommends that cardiologists more closely weigh the benefits and risks of statins given this new data about their effect on exercise training.
"Statins have only been used for about 15-20 years, so we don't know what the long-term effects of statins will be on aerobic fitness and overall health," Thyfault said. "If the drugs cause complications with improving or maintaining fitness, not everyone should be prescribed statins."
Thyfault and his colleagues measured cardiorespiratory fitness in 37 previously sedentary, obese individuals ages 25-59 with low fitness levels. The participants followed the same exercise regimen on the MU campus for 12 weeks; 18 of the 37 people also took 40 mg of simvastatin daily.
Statins significantly affected participants' exercise outcomes. Participants in the exercise-only group increased their cardiorespiratory fitness by an average of 10 percent compared to a 1.5 percent increase among participants also prescribed statins. Additionally, skeletal muscle mitochondrial content, the site where muscle cells turn oxygen into energy, decreased by 4.5 percent in the group taking statins while the exercise-only group had a 13 percent increase, a normal response following exercise training.
Thyfault suggests that future research determine whether lower doses of simvastatin or other types of statins similarly affect people's exercise outcomes and thus their risk for diseases such as Type 2 diabetes. Starting a statin regimen after exercising and obtaining a higher fitness level may reduce the drugs' effects on fitness, he says.

You already know this: Say one dark and stormy night, you have a weird/bad dream where your partner is not only doing something insanely shitty, like having sex with your best friend right in front of you, but is also laughing maniacally as you weep tears of shock/deep devastation. The next morning you look over at the jackal who so enthusiastically wounded you the night before, and think, the fuck if I'm getting him a coffee this morning. In other words, weird/bad dreams make you feel weird/bad. So you act weird/bad, too. But now science has your back.
?People?s activity changes as a function of the dream they had the night before ? specifically within the realm of their close relationships.?
That validating gem comes courtesy of lead researcher Dylan Selterman at the University of Maryland, who conducted a study of 61 people's relationships between their dreams and their, well, relationships. He had them keep dream journals for a few weeks, and log their activities, and measure the quality of their relationships. The folks in the study were 17 to 42 in age, and were all in committed relationships that had gone on at least six months.
He found that dreams have a "predictive value" in terms of their impact on the relationship. So what's coming out of your brain while you sleep isn't just always a benign release ? sometimes, it can leak over into the next day and leave your partner with some serious 'splainin' to do.
For example, after a dream involving a high degree of jealousy, the dreamer was more likely to report conflict with their partner during the day. Similarly, arguing in dreams was associated with next-day relationship conflict, while dreamer infidelity was linked with reduced feelings of love or intimacy afterward.
Selterman believes these correlations are the result of ?priming,? the process by which a stimulus evokes a related response. For instance, previous research has shown that placing someone on a wobbly chair triggers a desire for stable relationship partners.
This mechanism, of course, operates on a largely unconscious level.
Perhaps by dreaming these heinous acts in the first place, your brain is merely responding to the unrest/fear/distrust that already exists in your relationship by pushing it out in your dream state, thereby giving you a reason to discuss it or bring it into the cold, harsh light of day.
Or maybe your brain is purposely wobbling the chair of your relationship to make you consider whether it's time to move on. If that's true, it's just one more reason to love brains. Also worth loving is this: If bad dreams are just worries that may or may not have a basis in reality, the better the relationship, the better the ability to withstand these terrible dream interlopers and not let them disrupt things all that much.
The good news is that being in a healthy relationship appears to buffer people against the negative effects of dreams involving jealousy. And when it comes to sex dreams, those in good couplings spend the following days with a heightened sense of love and intimacy. By contrast, sex dreams had by people with poorer relationship health see the opposite effect.
This rings true to me: I've had far more upsetting dreams about the behavior of a partner in relationships that weren't going well. As for sex dreams, though, they seem more connected to the sexual activity of the relationship, or the rhythms of your own sex drive.
Over at Nerve, they explore the impact of sex dreams on a relationship further.
Taking a look at our most common sex dreams, a lot of us find ourselves in reveries with bosses, strangers, celebrities, same-sex or opposite-sex partners, and forbidden acquaintances. Some sex dreams might really be about true erotic fixations or primal impulses, as Freud suggested, but today?s psychologists say most are quite narcissistic and built upon underlying desires to absorb personality traits and attributes of those we seduce in our nighttime imaginations. These current interpretations of sex dreams complicate the notion that they could be impacting our relationships, negatively or positively. Are sex-based dreams that aren?t derived from libidinous impulses still impacting a fight or tension with our girlfriend or boyfriend? Probably.
Most of us have always figured that real events reflect dreams, but the idea that dreams, particularly sex dreams, could affect real life events challenges the consequence-free and boundless quality to our dreams. A lot of us experience instances when we feel our dreams have predicted certain events in our lives, but the new finding that we are being primed and influenced by dreams adds more to the story. Dreams, much like sex, come with unmoderated variability. As Selterman puts it, "Sex can be good or bad in a dream in the same way that it can be good or bad in real life."
And Selterman would know: The study was apparently inspired by the conflicts caused in his own college relationship, when a girlfriend got ticked off at him over his bad dream behavior.
So if our dreams can be a kind of litmus test for our worries about the health of our relationships, what is one to do about them?
At the very least, take note, and don't be too nonchalant when your partner has a disturbing dream and wants to talk about it. Give reassurance that you aren't a terrible two-headed hydra, even if it feels silly to do that for a dream.
We may be grown adults, but we can still have nightmares. For adults, that can be as simple as finding out that our relationships are not as stable as we hoped. The trick here is determining whether the source of the worry the dream depicts is real, or all in your head. And if nothing else, perhaps this study helps us finally acknowledge that our dreams just might be trying to tell us something. Even if we don't like what it is.

If you ever stared at a chrysalis as a kid, patiently waiting for a beautiful new butterfly to emerge, you were probably left wondering just what was going on inside there. Was the caterpillar reconfiguring itself like a Transformer? Was it morphing like a Terminator? Nobody knows?except now everyone does thanks to these fascinating micro-CT 3D x-ray scans of the process.
Two research teams used the cutting edge imaging technique to routinely scan a chrysalis during its metamorphosis and generate 3D models of its organs and other internal structures changing over time. Smaller details?like details of the brain?are unfortunately still left out with the limitations of the technology. But as they improve, so will our understanding of this unique process. Not to mention, kids won't have to wait weeks to see a butterfly finally emerge?they can just hit fast forward. [National Geographic via Boing Boing]

They promise to do their bit for the environment and stick eco labels on their products. But sooner or later someone will point out that they sell products that are pesticide-ridden or that contain palm oil sourced from endangered rainforests. Did the entrepreneurs reach their decision after a rational cost/benefit analysis? Or does unconscious behavior play a bigger role in entrepreneurial decision-making than is often assumed? What are the triggers that cause entrepreneurs to act against their own values? To find the answers to these questions, economic researchers from Technische Universitt Mnchen (TUM), Indiana University, and Oklahoma State University presented a range of scenarios to around 100 German business founders.
For the task, the entrepreneurs were asked to assess a variety of business opportunities against a number of attributes. They were asked first of all to assess the attractiveness of a particular business opportunity. They were also asked to make a set of judgments in the context of environmental impact, respect for nature, entrepreneurial self-efficacy and perceived business climate. Using the interconnected variables of this conjoint experiment, the researchers were able to draw conclusions on how various cognitive processes influence decision-making.
The research team found that even entrepreneurs with a strong respect for nature made decisions with a harmful effect on the environment. These decisions were not reached on the basis of any conscious process, however. "We found that the research subjects unconsciously adjusted the relationship between their values and their actions - with the effect that their actions seemed to coincide once more with their values," explains Prof. Holger Patzelt of the Chair of Entrepreneurship at TUM.
The researchers noted, however, that not all of the entrepreneurs displayed this disengagement of pro-environmental values. What these entrepreneurs had in common was a high level of entrepreneurial self-efficacy and a challenging business climate. According to the received theory up to now, entrepreneurs with low self-efficacy were thought more likely to experience a conflict with their own values.
Holger Patzelt comments further on the findings of the "I care about nature, but ..." study: "Entrepreneurs with very high entrepreneurial self-efficacy want to exert influence. This makes them more likely to disengage from values that limit their options. The same principle applies to an unfavorable industry environment, for example if the company is facing sharp competition. In such situations, too, company bosses believe that everything hinges on their decisions."
Meanwhile, the researchers' findings could be used to good effect in environmental legislation. "Law-makers could pass stronger regulations in industries prone to challenging economic climates with a view to protecting the environment," suggests Patzelt. For the entrepreneurs themselves, the findings on unconscious decision-making mechanisms could help them gain more insight into their own business strategies. Last but not least, the researchers hope that their work will help to improve the structure of training. "Up to now, economics courses have placed an emphasis on turning out budding entrepreneurs with a high degree of entrepreneurial self-efficacy," remarks Patzelt.
"Now we know that this strategy can also have undesired consequences."

Officials in Belize say a construction company has destroyed one of the country's largest Mayan pyramids.
Head of the Belizean Institute of Archaeology Jaime Awe said the Noh Mul temple was levelled by a road-building company seeking gravel for road filler.
The Mayan temple dates back to pre-Columbian times and is estimated to be 2,300 year old. Only a small core of the pyramid was left standing.
Police said they were investigating the incident.
Archaeologists said this was not the first incident of its kind.
"Bulldozing Maya mounds for road fill is an endemic problem in Belize," Prof Normand Hammond told the Associated Press news agency.
Archaeologists said they were alerted to the destruction late last week.
The Maya complex lies on private land but under Belizean law, any pre-Hispanic ruins come under government protection.
Dr John Morris of the Belizean Institute of Archaeology said the workers would have been aware of what they were doing.
"It is incredible that someone would actually have the gall to destroy this building out here," he told local TV channel News 7.
"There is absolutely no way that they would not know that these are Maya mounds," he said about the ancient structure.
Prosecutors said they were considering bringing criminal charges against the construction company.

May 13, 2013 ? Earthquakes similar in magnitude to the 2004 Sumatra earthquake could occur in an area beneath the Arabian Sea at the Makran subduction zone, according to recent research published in Geophysical Research Letters.
The research was carried out by scientists from the University of Southampton based at the National Oceanography Centre Southampton (NOCS), and the Pacific Geoscience Centre, Natural Resources Canada.
The study suggests that the risk from undersea earthquakes and associated tsunami in this area of the Western Indian Ocean -- which could threaten the coastlines of Pakistan, Iran, Oman, India and potentially further afield -- has been previously underestimated. The results highlight the need for further investigation of pre-historic earthquakes and should be fed into hazard assessment and planning for the region.
Subduction zones are areas where two of Earth's tectonic plates collide and one is pushed beneath the other. When an earthquake occurs here, the seabed moves horizontally and vertically as the pressure is released, displacing large volumes of water that can result in a tsunami.
The Makran subduction zone has shown little earthquake activity since a magnitude 8.1 earthquake in 1945 and magnitude 7.3 in 1947. Because of its relatively low seismicity and limited recorded historic earthquakes it has often been considered incapable of generating major earthquakes.
Plate boundary faults at subduction zones are expected to be prone to rupture generating earthquakes at temperatures of between 150 and 450 ?C. The scientists used this relationship to map out the area of the potential fault rupture zone beneath the Makran by calculating the temperatures where the plates meet. Larger fault rupture zones result in larger magnitude earthquakes.
"Thermal modelling suggests that the potential earthquake rupture zone extends a long way northward, to a width of up to 350 kilometres which is unusually wide relative to most other subduction zones," says Gemma Smith, lead author and PhD student at University of Southampton School of Ocean and Earth Science, which is based at NOCS.
The team also found that the thickness of the sediment on the subducting plate could be a contributing factor to the magnitude of an earthquake and tsunami there.
"If the sediments between the plates are too weak then they might not be strong enough to allow the strain between the two plates to build up," says Smith. "But here we see much thicker sediments than usual, which means the deeper sediments will be more compressed and warmer. The heat and pressure make the sediments stronger. This results in the shallowest part of the subduction zone fault being potentially capable of slipping during an earthquake.
"These combined factors mean the Makran subduction zone is potentially capable of producing major earthquakes, up to magnitude 8.7-9.2. Past assumptions may have significantly underestimated the earthquake and tsunami hazard in this region."

The Food Standards Agency (FSA) explored the idea of testing all horses slaughtered in the UK months before the horsemeat food crisis began in January.
But the agency was concerned that the costs of extra testing would cause every horse abattoir to close down.
Without the faster tests, it is likely that meat tainted with phenylbutazone continued to enter the food chain.
The agency says the testing was delayed to allow a comprehensive review of all the impacts.
The number of horses presented for slaughter in the UK has doubled in recent years, with more than 9,000 animals killed at the five approved abattoirs in 2012. Most of the meat was exported to Europe.
Fraudulent passportsAnimals that have been treated with the anti-inflammatory medicine phenylbutazone or bute are legally barred from entering the food chain. Details of any treatment with the drug are meant to be recorded in a passport document.
But the UK has had considerable problems with fraudulent passports due to the large number of organisations of varying quality licensed to issue the documents.
Last year the FSA was made aware that increasing numbers of horses with questionable passports were turning up at abattoirs. In the summer it implemented a series of extra tests to determine if bute-tainted meat was getting through.
The problem with testing for the drug is that it can take two weeks to get a result. By the time the agency knew the carcass was positive or negative, the meat had already been shipped on to markets across the EU.
From its extra testing, the FSA learned that around 6% of horses were positive for bute, meaning that potentially hundreds of animals with the drugs in their system were going into the food chain.
The agency did introduce a "positive release system" - meaning the horsemeat was released only when certified drug-free on 11 February, once the crisis over horsemeat in beef products had begun.
But in emails released to the BBC under the Freedom of Information act, senior officials at the agency were shown to be looking into the costs of more rapid tests on 5 November, more than three months earlier.
So why was the more rapid system not put in place earlier?
"In any decision we could have made back in November we needed the evidence," Andrew Rhodes, the FSA's director of operations said.
"In November what you see in all the records is us seeking the evidence - the evidence we finished gathering early this year and we were able to make a decision on what we would do next and that was to introduce a positive release system."
'Questions to answer'Labour shadow environment secretary Mary Creagh said the only reason the extra testing was finally introduced was because of the discovery of horsemeat in beef products. The real responsibility for the delayed testing, she said, lay with the government.
"We now know that in November plans were drawn up to test every horse slaughtered, yet nothing was done until after the horsemeat scandal hit the headlines," she said.
"Incompetent ministers have questions to answer about why these early warnings were ignored which led to bute-contaminated horsemeat being consumed."
The FSA rejects the idea that it introduced the positive release system only in response to the crisis - it said it was going to happen anyway.
It was concerned that the price of putting in place a 48-hour testing regime was very high.
Mr Rhodes said it was "more than likely" that the extra costs would have essentially closed down the slaughter industry.
"The average value of a horse carcass is anywhere up to ?300, maybe a little more," he said.
"The test we were looking at, the time for the 48-hour turnaround was the same or more than the cost of the actual carcass and that would have caused problems in terms of passing on any cost.
'Underground trade'"But what we have to remember is that we didn't have the evidence base back then to make the decision that we were able to make earlier this year."
The FSA was concerned that if abattoirs closed down, there would be a range of knock-on problems that would also have cost money to deal with.
"If we had stopped the industry operating then we might have seen all kinds of animal welfare issues as well as possible illegal slaughter and the trade going underground," Mr Rhodes added.
"That's not a good thing for consumers, it's much more important that we regulated the industry legally and that we find a way of making that work and that's what we've done."
Testing for bute is likely to continue for at least another year, he added, saying that there were still ongoing problems with the drug.
Mr Rhodes also said that owners and vets "aren't always signing [horses] out of the food chain when they should be, we see that in the investigations we carried out.
"Until that changes there will be a need to control the animals going into the food chain."

MUSKEGON, Mich. Grand Valley State University's Michigan Alternative and Renewable Energy Center received a grant from the Michigan Energy Office to study solar thermal system costs and efficiency improvements for use in Michigan's climate.
Kim Walton, program director for MAREC, said some large solar energy systems that are being installed in West Michigan are based on design criteria that come from other parts of the country, and may or may not be optimal for the West Michigan region.
"West Michigan is an area where very little solar research has been conducted," she said. "Understanding how different factors work together can help installers of the solar systems design the most efficient systems and lower overall costs."
The $44,000 grant will fund data collection over a one-year period. Walton will collect data from homes in the Muskegon-Oceana area that received renewable energy systems from a grant from Sustainable Energy Resources for Consumers in November of 2011. The residential data that will be collected includes the type of technology used, mounting factors, costs for materials, labor, fees and permits.
Data will also be collected from photovoltaic (PV) panel test beds that were constructed and installed at MAREC. The test beds consist of PV panels with micro inverters configured to provide specific output data for solar panel angles and interaction of snow cover. The PV test beds are installed next to MAREC's Solar Center, a space that houses solar equipment that is used for research and training in classes and other activities.
Walton said while the study is funded for one year, she plans to continue to gather data for several years.

Data will also be collected from photovoltaic (PV) panel test beds that were constructed and installed at MAREC. The test beds consist of PV panels with micro inverters configured to provide specific output data for solar panel angles and interaction of snow cover. The PV test beds are installed next to MAREC's Solar Center, a space that houses solar equipment that is used for research and training in classes and other activities.
Walton said while the study is funded for one year, she plans to continue to gather data for several years.

People should not underestimate the power of a bright warm smile. A mouth filled with sturdy, white teeth and pink healthy gums tells the globe that you are a healthy and hygienic person, even if that smile was flashed for only an instant. This is why dental field is such a lucrative business: people want to be known as the person with the killer smile.
Healthy teeth are not something you wake up to one day after long years of neglect. Getting a fantastic set means year of dental care. A person has to make taking care of one?s teeth a habit. This does not only mean brushing your teeth. It also involves flossing and annual dental washing for removal of plaque.
Throughout history, though, brushing still remains the king in taking care of one?s teeth. We human beings have protected our teeth in this way. Way back in the days, the soft end of a tiny twig was used to remove the remains of last night?s meal. Nowadays, improved toothbrushes have been coming out in the market that promises to do a more thorough job by reaching areas you usually can?t.
Some folks, however, are not as careful as they ought to be when it comes to oral hygiene. They forget to brush their tooth or use mouthwash or dental floss. What they end up with are oral diseases such as bad breath and tooth decay. Some signs of a mouth diseases are bleeding gums, dark-colored gums, discolored teeth and of course, wide cavities in teeth.
When this happens, it could lead to great pain. But it is not always the case, some pain is caused by misaligned teeth or teeth that doesn?t grow in the correct position. Your wisdom tooth could give your problems by coming out sideways. This is a place where brushing or flossing couldn?t help you.

With President Obama dispatching Secretary of State John Kerry to Moscow even as Israel launches targeted airstrikes on Damascus, this could turn out to be a decisive week for US involvement in the Syrian conflict.
Mr. Obama has long sought to keep the United States out of what would likely be an attention-consuming, domestically unpopular, and ultimately inconclusive US intervention in Syria?s civil war. But with the war reaching new levels of violence and now seriously threatening to spill over into a regional conflict, the president may have little choice but to reverse course and intervene in some way.
What, if anything, Secretary Kerry is able to work out with the Russians in terms of international pressure on Syria, and where Israel?s weekend strikes lead in the coming days, are likely to alter the course of US action. In any event, both components are part of a scenario of suddenly expanding pressure on Obama to move decisively on Syria.

?This is a risk-averse president ? rightly so in this case, I would add ? being pulled closer and closer to some kind of intervention,? says Aaron David Miller, a Middle East expert at the Woodrow Wilson International Center for Scholars in Washington.
?At some point he?ll push it a step further? and decide what to do, Mr. Miller says ? perhaps choosing from a set of options administration officials are presenting that range from arming the rebels to establishing a no-fly zone over northern Syria.
But Obama is as keenly aware as anyone that there are no good options for resolving the Syrian crisis, says Miller, a former State Department adviser on Middle East issues with experience in both Democratic and Republican administrations.

?Whatever the US decides to do, it won?t be precipitous action? that somehow brings to an end, he says, a 2-year-old war that has left 76,000 Syrians dead and hardened internal divisions to the breaking point.
An ongoing debate in the administration over whether to intervene ? and if so, in what manner ? has shifted in recent weeks in favor of some form of intervention, some US officials say. At a Pentagon press conference last week, Defense Secretary Chuck Hagel said the US was in the process of ?rethink[ing] all options.?
That shift, prompted in part by evidence that chemical weapons were used in the conflict, could accelerate, they add, if there are signs of a dangerous expansion of the war into a broader conflict.
On Sunday, Israel reportedly struck targets in Syria twice, in one case hitting missiles thought to be destined for Hezbollah, the Lebanon-based Shiite Muslim organization that is actively aiding Syrian President Bashar al-Assad in his fight with largely Sunni rebels. Israel has long said its top concern in the Syrian conflict is the potential for transfer of weaponry to its enemies.
Kerry, who will meet in Moscow with President Vladimir Putin and Foreign Minister Sergei Lavrov, could use the latest events in Syria to try to extract a more cooperative stance from Russia, which continues to shield Mr. Assad from international pressure to step down and make way for a political transition.
The US and Russia joined other international powers last year in calling for a political transition in Syria, but no progress has been made in that direction since then. The US wants to see if Russia is ready to move forward on Syria ? both as a result of recent events and given signs that the US is moving closer to intervention in the absence of international diplomatic action, senior administration officials say.
?Events have moved forward on the ground, and so this is a time to talk to the Russians, [for them] to understand that from our side, we remain committed, and if they are as well, then we need to think about how to work operationally to make [a political transition] happen,? says a senior State Department official, who spoke on condition of anonymity.
Up to now, the US has stopped short of providing Syrian rebels with lethal assistance, in part over concerns that weapons such as shoulder-fired antiaircraft missiles could fall into the hands of the radical Islamists among the rebels. But the White House is thought to be leaning toward providing arms under some sort of vetting system.
Some members of Congress, including Republican senators John McCain of Arizona and Lindsey Graham of South Carolina, are calling for the US to establish a no-fly zone over parts of Syria to create havens for civilians and rebels.
Virtually no one is calling for American boots on the ground. But even an intervention with no US soldiers ordered into Syria has only minimal support from Americans. And that presents Obama with a scenario he has sought to avoid: announcing to war-weary Americans yet another Middle East intervention.
A new Christian Science Monitor/TIPP poll shows nearly two-thirds of Americans ? 62 percent ? oppose US intervention in Syria, with only a quarter in favor. Those results are in line with other recent polls gauging the US appetite for military intervention in Syria.
The Monitor poll, taken April 30-May 4 among 825 respondents, found that even solid evidence of the Assad regime using chemical weapons against its own people would not shift the balance in favor of US military action. In such a case, 48 percent of Americans said they would favor continuing humanitarian assistance to civilians and some ?technological assistance? to the rebels.
But only 12 percent said chemical weapons would be cause enough for the US to help arm the rebels, while 13 percent said it should prompt the use of US air power in the conflict.
The average American?s reluctance to see the US intervene in Syria may have only been reinforced by events since the poll was taken. Both the Israeli airstrikes in Syria and reports Monday from a UN official of evidence that some rebels used the nerve agent sarin in their fighting should leave the US even more cautious, some say.
The rebels? reported use of sarin ?shows how little the [US] government really knows about what?s going on in this complex and bloody civil war, [and] it should make us extremely cautious about becoming involved militarily and reluctant about providing military support for the Syrian rebels,? says David Cortright, director of policy studies at the University of Notre Dame?s Kroc Institute for International Peace Studies in Indiana.
Some pro-intervention voices in Washington jumped quickly on the Israeli airstrikes as further proof of resolute Israeli action in the face of an indecisive US administration. But others, like Mr. Cortright, say the Israeli action only further complicates a thicket the US should avoid.
?The Israeli attacks against Syria are a blatant violation of international law,? he says. ?They increase the risk of the conflict spreading further in the region and should make us even more hesitant about becoming involved militarily.?

MIAMI (AP) ? The writer who did not choose LeBron James of the Miami Heat as the NBA's Most Valuable Player believes Carmelo Anthony "meant more to his team" this season.
Gary Washburn of The Boston Globe says Anthony made the New York Knicks relevant again by leading them to their first division title in nearly two decades. Washburn's explanation was published Monday, one day after James won his fourth MVP award.
Washburn says the Knicks would not have made the playoffs without Anthony, while the Heat have plenty of other talent besides James. Washburn also says that he believes James will eventually become the league's first seven-time MVP and that his vote was "no LeBron conspiracy."
James collected 120 of 121 first-place votes. The NBA has never had a unanimous MVP selection.
