Some of the benefits of exercise may be related to the placebo effect.

How is this for an abstract….

ABSTRACT—In a study testing whether the relationship between exercise and health is moderated by one’s mind-set, 84 female room attendants working in seven different hotels were measured on physiological health variables affected by exercise. Those in the informed condition were told that the work they do (cleaning hotel rooms) is good exercise and satisfies the Surgeon General’s recommendations for an active lifestyle. Examples of how their work was exercise were provided. Subjects in the control group were not given this information. Although actual behavior did not change, 4 weeks after the intervention, the informed group perceived themselves to be getting significantly more exercise than before. As a result, compared with the control group, they showed a decrease in weight, blood pressure, body fat, waist-to-hip ratio, and body mass index. These results support the hypothesis that exercise affects health in part or in whole via the placebo effect.

H/T Overcoming Bias

Some people just can't be made happy….

I am always being told that global warming is going to raise sea leaves and such. So you think that people living on an island would be happy to have an earthquake that rises said island up in the air by 10 feet. But no, they are crying about what a catastrophe it is (h/t Pierre Legrand).

In an instant, the grinding of the Earth’s tectonic plates in the 8.0 magnitude earthquake Monday forced the island of Ranongga up three metres (10 foot).

Submerged reefs that once attracted scuba divers from around the globe lie exposed and dying after the quake raised the mountainous landmass, which is 32-kilometres (20-miles) long and 8-kilometres (5-miles) wide.

Corals that used to form an underwater wonderland of iridescent blues, greens and reds now bleach under the sun, transforming into a barren moonscape surrounding the island.

The stench of rotting fish and other marine life stranded on the reefs when the seas receded is overwhelming and the once vibrant coral is dry and crunches underfoot.

Dazed villagers stand on the shoreline, still coming to terms with the cataclysmic shift that changed the geography of their island forever, pushing the shoreline out to sea by up to 70 metres.

Snark aside, I do feel for the actual people affected, but I think that it is cool that an earthquake can raise an entire Island by 10 feet.

NYT Article on Alzheimer’s

Below is a link to a NYT article on people trying to live with Alzheimer’s. The observations in the article line up with my own. If you read the article you will see there is one man profiled who still retains his short term memory but is losing his motor skill rapidly. Then there is a lady who retains her motor skills better but has completely lost her short term memory. Grandpa isn’t so much to one extreme or the other, but those cases reflect how Alzheimer’s progresses differently for every individual.

I would say Grandpa has lost probably short term memory and motor skills in equal measure. He hasn’t lost either entirely, but both are getting progessively worse.

Is antibacterial soap really worthless?

I found an interesting article entitled Wound Care: An Emergency Room Doctor’s Perspective, by E.C.W., MD on Survivalblog.com. I don’t really doubt anything E.C.W says, but I would have liked to see more references and documentation. Particularly for statements like this…..

Plain soap and tap water have been shown to be just as good for washing the wound as an antiseptic soap and sterile water. It turns out that some of the antiseptic solutions available kill so much good tissue that they are not preferable to regular soap. I would recommend a liquid soap, to avoid the bacterial culture waiting to launch itself from the bar on the counter, but would avoid the “antibacterial soap” (with triclosan) widely available that has been shown to increase bacterial resistance. In a perfect world I would prefer Hibiclens, but would certainly use a “no-tears” baby shampoo (neutral solution) or even diluted Dawn. One could apply it to a clean washcloth wet from the tap and use it to gently scrub the wound.

Now I am instinctively distrustful of “antibacterial soap” so I don’t find that statement beyond belief. But I have to wonder if plain soap and tap water are as good as antiseptic soap and sterile water under all circumstances. Seems to me that you could have some very messy wounds where you would want to use a very powerful antibacterial soap.

Maybe the studies that the good doctor mentions examined the issue of messy/dirty wounds and still found regular soap to be just as good. But regardless, I would like to know more about those studies.

Big Solar Storm Coming?

Wonder if this is any more accurate then our weather forecasts….

This week researchers announced that a storm is coming–the most intense solar maximum in fifty years. The prediction comes from a team led by Mausumi Dikpati of the National Center for Atmospheric Research (NCAR). “The next sunspot cycle will be 30% to 50% stronger than the previous one,” she says. If correct, the years ahead could produce a burst of solar activity second only to the historic Solar Max of 1958.

That was a solar maximum. The Space Age was just beginning: Sputnik was launched in Oct. 1957 and Explorer 1 (the first US satellite) in Jan. 1958. In 1958 you couldn’t tell that a solar storm was underway by looking at the bars on your cell phone; cell phones didn’t exist. Even so, people knew something big was happening when Northern Lights were sighted three times in Mexico. A similar maximum now would be noticed by its effect on cell phones, GPS, weather satellites and many other modern technologies.

Dikpati’s prediction is unprecedented. In nearly-two centuries since the 11-year sunspot cycle was discovered, scientists have struggled to predict the size of future maxima—and failed. Solar maxima can be intense, as in 1958, or barely detectable, as in 1805, obeying no obvious pattern.

The rest of the article talks about the conveyor belt that they think operates on the sun.

Invoking the Tooth Fairy Twice……

There is an interesting article in the New York Times on dark matter and dark energy. A quote from the article…..

And if the right ripples hadn’t shown up? As Frieman puts it: “You just would have thrown up your hands and said, ‘My God, we’ve got to go back to the drawing board!’ What’s remarkable to me is that so far that hasn’t happpened.”

Yet in a way it has. In the observation-and-theory, call-and-response system of investigating nature that scientists have refined over the past 400 years, the dark side of the universe represents a disruption. General relativity helped explain the observations of the expanding universe, which led to the idea of the big bang, which anticipated the observations of the cosmic-microwave background, which led to the revival of Einstein’s cosmological constant, which anticipated the observations of supernovae, which led to dark energy. And dark energy is … ?

The difficulty in answering that question has led some cosmologists to ask an even deeper question: Does dark energy even exist? Or is it perhaps an inference too far? Cosmologists have another saying they like to cite: “You get to invoke the tooth fairy only once,” meaning dark matter, “but now we have to invoke the tooth fairy twice,” meaning dark energy.

The article makes me think of the argument in Spinoza, Einstein, and the Failure of Reason. Especially those places in the article were they are speculating that the answer might be more complicated then we can conceive.

Why are there no Honeybees anymore?

According to the New York Times, the answer cannot be blamed just on the varroa mites. They say that there is more to it then that. An excerpt from the article…..

Beekeepers have fought regional bee crises before, but this is the first national affliction.

Now, in a mystery worthy of Agatha Christie, bees are flying off in search of pollen and nectar and simply never returning to their colonies. And nobody knows why. Researchers say the bees are presumably dying in the fields, perhaps becoming exhausted or simply disoriented and eventually falling victim to the cold.

As researchers scramble to find answers to the syndrome they have decided to call “colony collapse disorder,” growers are becoming openly nervous about the capability of the commercial bee industry to meet the growing demand for bees to pollinate dozens of crops, from almonds to avocados to kiwis.
