Birds evolved compass 'head up display'
"Certain birds may have compass information mapped directly onto their vision, much as fighter pilots have ‘head up displays’ overlaying flight information on their view of the skies.'
"According to the new model, when a photon of light from the Sun is absorbed by a special molecule in the bird's eye, it can cause an electron to be kicked from its normal state into an alternative location a few nanometres away. Until the electron eventually relaxes back, it creates an ‘electric dipole field’ which can augment the bird's vision - for example altering colours or brightness.
"Crucially, the alignment of the molecule compared to the Earth's magnetic field controls the time it takes for the electron to relax back, and so controls the strength of the effect on the bird's vision.
"There are many such molecules spread throughout the eye, with different orientations. So from the patterns on top of its vision, and the change of these patterns as it moves its head, the bird learns about the direction of Earth's magnetic field."

Wordly wisdom
"Why are some words short and others long? For decades, a prominent theory has held that words used frequently are short in order to make language efficient: It would not be economical if “the” were as long as “phenomenology,” in this view. But now a team of MIT cognitive scientists has developed an alternative notion, on the basis of new research: A word’s length reflects the amount of information it contains."

Scott and Scurvy
'Finally, that one of the simplest of diseases managed to utterly confound us for so long, at the cost of millions of lives, even after we had stumbled across an unequivocal cure. It makes you wonder how many incurable ailments of the modern world - depression, autism, hypertension, obesity - will turn out to have equally simple solutions, once we are able to see them in the correct light. What will we be slapping our foreheads about sixty years from now, wondering how we missed something so obvious? [...] the villain here is just good old human ignorance, that master of disguise. We tend to think that knowledge, once acquired, is something permanent. Instead, even holding on to it requires constant, careful effort.'

GPS and Relativity
'The combination of these two relativitic effects means that the clocks on-board each satellite should tick faster than identical clocks on the ground by about 38 microseconds per day (45-7=38)! This sounds small, but the high-precision required of the GPS system requires nanosecond accuracy, and 38 microseconds is 38,000 nanoseconds. If these effects were not properly taken into account, a navigational fix based on the GPS constellation would be false after only 2 minutes, and errors in global positions would continue to accumulate at a rate of about 10 kilometers each day!'

The Origin of Big | The Loom | Discover Magazine
'If the scientists are right, they may have discovered one of the big ironies in evolution. Lunge-feeding may have allowed whales to become the biggest animals ever to roam the planet. But this was not an open-ended invitation.r. Once whales got large enough, lunge feeding itself became so costly it prevented them from getting any bigger. Perhaps some day another animal will evolve a new strategy that will let it get even bigger than a blue whale. But for the animal kingdom as we know it, we may be sharing the planet with the biggest species it can offer.'

The Nutt Sack Affair (part 493)
'a strange reasoning twitch has appeared, in the arguments of politicians and right wing commentators. Science can tell us about the molecules, they say, about their effect on the body, and the risks. But policy is a separate domain: a matter for judgement calls on social and ethical issues. Only politicians, they say, can determine the correct way to send out a clear message to the public. It is not a matter for science.
Interestingly this is wrong. Alongside research into the risks of drugs, lots of research has also been done examining the deterrent impact of different laws, classifications, and levels of enforcement. Since every piece of research has its own imperfections (and nobody has yet conducted a randomised controlled trial on drugs policy) you can make your own mind up about whether you find this research compelling.'

Placebos Are Getting More Effective. Drugmakers Are Desperate to Know Why.
'It's not only trials of new drugs that are crossing the futility boundary. Some products that have been on the market for decades, like Prozac, are faltering in more recent follow-up tests. In many cases, these are the compounds that, in the late '90s, made Big Pharma more profitable than Big Oil. But if these same drugs were vetted now, the FDA might not approve some of them. Two comprehensive analyses of antidepressant trials have uncovered a dramatic increase in placebo response since the 1980s. One estimated that the so-called effect size (a measure of statistical significance) in placebo groups had nearly doubled over that time.'

Code: Flickr Developer Blog » Found in space
"A robot intelligence has invaded Flickr. The “blind astrometry server” is a program which monitors the Astrometry group on Flickr, looking for new photos of the night sky. It then analyzes each photo, and from the unique star positions shown it figures out what part of the sky was photographed and what interesting planets, galaxies or nebulae are contained within. Not only does the photographer get a high-quality description of what’s in their photo, but the main Astrometry.net project gets a new image to add to its storehouse of knowledge."

Acceleration Due to Gravity: Super Mario Brothers
"We determined that, generally speaking, the gravity in each Mario game, as game hardware has increased, is getting closer to the true value of gravity on earth of 9.8 m/s2. However, gravity, even on the newest consoles, is still extreme. According to Wikipedia, a typical person can withstand 5 g before losing consciousness, and all but the very latest of Mario games have gravity greater than this. Also, with gravity that great, it is a wonder Mario can perform such feats as leaping almost 5 times his own body height!"

"In the past few days, the researchers have seen areas of sea foaming with gas bubbling up through "methane chimneys" rising from the sea floor. They believe that the sub-sea layer of permafrost, which has acted like a "lid" to prevent the gas from escaping, has melted away to allow methane to rise from underground deposits formed before the last ice age."
