Researchers found new evidence of the importance of make-up while studying Spanish flamenco dancers flamingos. The scientists discovered that the birds augment their signature coloring by applying tints drawn from their own glands–and they use their painted plumage to attract mates.
The hue of the leggy birds’ feathers come primarily from the pigments in their diet, but researcher Juan Amat found that they also secrete the colored pigments, called carotenoids, from their preen glands. Flamingos (and many other birds) press their heads to the preen glands at the base of their tails to pick up feather-protecting oils, which they then spread around their bodies.
The researchers realized that those oils contain pigments, ranging from red to yellow, by keeping an eye on the flamingos’ feathers and behavior: They noticed that the coloring of the birds was brightest during the mating season, and quickly diminished after they found a mate. Amat told BBC News:
“The rubbing is time-consuming,” Dr Amat told BBC News. “And the more frequently the birds practise it, the more coloured they appear. If the birds stop the rubbing, [their] plumage colour fades in a few days because carotenoids[pigments] bleach quickly in the sunlight.”
Charges by South Korean health officials that octopus heads contain large and unhealthy amounts of the heavy medal cadmium have sparked a war with the fishermen who profit from the $35 million-a-year trade.
Octopus heads are a popular delicacy in South Korea, revered by locals for their health benefits and their supposed role as an aphrodisiac. About 12 million octopuses are sold for eating every year, says the LA Times:
Nakji, a dish featuring baby octopuses, head and all, is a popular snack at sporting events. Another dish, sannakji (“live octopus”), features squirming tentacles dipped in a sesame oil and salt sauce. Enthusiasts have been hospitalized after a wiggling tentacle lodged in the throat.
Ncell, a subsidiary of the Swedish telecom company TeliaSonera, has installed a 3G data network in a Nepalese town that should reach the summit of Mount Everest. This high up, high-tech improvement will allow summit-ers to communicate with friends, family, and organizers from the top of the world.
A phone base station was set up near the town of Gorakshep at 17,000 feet above sea level, and the signal should reach to the peak about 12,000 feet above that, telecom officials said–but it hasn’t been tested yet. The service should be fast enough to allow adventurers to make video calls and surf the Internet from their phones.
Lars Nyberg, CEO of TeliaSonera, told the Associated Foreign Press how excited they were to take the mountain into the wireless internet age:
“This is a great milestone for mobile communications as the 3G high speed internet will bring faster, more affordable telecommunication services from the world’s tallest mountain,” said Lars Nyberg.
“BACKGROUND: Individuals’ faces communicate a great deal of information about them. Although some of this information tends to be perceptually obvious (such as race and sex), much of it is perceptually ambiguous, without clear or obvious visual cues. METHODOLOGY/PRINCIPAL FINDINGS: Here we found that individuals’ political affiliations could be accurately discerned from their faces. Read More
There are many different kinds of intelligent. Are you book smart? Street smart? Good at school and test-taking smart? Good at schmoozing your way out of deadlines and into jobs smart? Better at writing or math?
One new intelligence test, put online today by New Scientist and the Discovery Channel, claims to be the best test of overall smarts. The test was designed by neuropsychologist Adrian Owen to test 12 different “pillars” of wisdom, and to work every part of your mind.
From Owen’s article about the test for New Scientist:
Like many researchers before us, we began by looking for the smallest number of tests that could cover the broadest range of cognitive skills that are believed to contribute to intelligence, from memory to planning.
But we went one step further. Thanks to recent work with brain scanners, we could make sure that the tests involved as much of the brain as possible – from the outer layers, responsible for higher thought, to deeper-lying structures such as the hippocampus, which is involved in memory.
As an intrepid blogger, I went ahead and took the test. Some of the exercises resembled classic games like “Memory” (to test paired associates learning, you’re asked to remember what items are hidden where) and “Simon” (to test working memory, you have to remember sequences). Others are more similar to cognitive psychology tests like the Stroop test (which tests focused attention), and there are also some puzzle-solving tests (to test your ability to plan for the future).
The 12 tests are designed to test 12 different aspects of working memory, reasoning, focus, and planning. I did the worst on the “verbal working memory” test, which was reading a string of numbers and typing it in from memory. This actually makes sense, because I’ve always known myself to be a physical learner, and highlight or write down everything I hear that I need to remember. I wonder if there is a correlation there?
You can only take the test once, so make sure to do some mental push-ups first before diving in. Then come back here and tell us what you thought! Also, visit www.cambridgebrainsciences.com to play additional games, to train your brain, and to test your 12 pillars.

Having a bee brain might not be so bad after all, since new research shows that bees are faster than supercomputers when it came to solving one of those dreadful “word problems” from (probably very advanced) high school math class.
“There is a common perception that smaller brains constrain animals to be simple reflex machines. But our work with bees shows advanced cognitive capacities with very limited neuron numbers.”
The problem is called the traveling salesman problem, and the bees’ lives actually depend on solving it every day. The traveling salesman needs to visit a number of cities in the shortest amount of time, without repeating a visit. The traveling bumblebee needs to visit a number of flowers everyday, while expending as little energy as possible. Queen Mary University of London researcher Lars Chittka explained in the press release why studying bees’ habits is important:
Dominance, politics, and physiology: voters’ testosterone changes on the night of the 2008 United States presidential election.
“BACKGROUND: Political elections are dominance competitions. When men win a dominance competition, their testosterone levels rise or remain stable to resist a circadian decline; and when they lose, their testosterone levels fall. However, it is unknown whether this pattern of testosterone change extends beyond interpersonal competitions to the vicarious experience of winning or losing in the context of political elections.

The locals living in a remote Burmese forest gave wildlife biologists very clear instructions on how to find a rare species of monkey: Just go out on a rainy day, and listen for sneezes in the treetops. The snub-nosed monkey has nostrils that point up, they said, and it sneezes when rainwater drips into its nose.
Even with these amazingly great directions, the biologists failed to photograph a live specimen of the Burmese snub-nosed monkey–the image at right is a digital reconstruction of what the monkey probably looks like. Still, their examination of skins and skulls in the villagers’ possession provided enough evidence to declare that the monkey was a new species that had never before been described in the scientific literature.
