Hygienic Sharks
19 March 2010 -Scientists filmed sharks off the coast of the Philippines visiting a tropical seamount - or undersea mountain. This is a habitat for cleaner fish, which nibble off parasites and dead skin.The sharks repeatedly visited the station and swam slowly around, giving the fish time to delouse them.The findings were recently published in the journal PLoS One.This is the first time the behaviour has been seen in this species and the researchers say it shows how vital these shallow reef habitats are for the large, threatened predators. The lead researcher, Simon Oliver from Bangor University in the UK, has been studying thresher sharks for more than five years and founded the Thresher Shark Research and Conservation Project. For the PLoS One Study, he filmed over 1,000 hours of footage of the sharks at a seamount off the northern tip of Cebu in the Philippines. "They visit the site very regularly," Mr Oliver told BBC News. "A huge dive tourism site has evolved around them."The sharks' behaviour suggests that they go there specifically to be cleaned."They pose, lowering their tails to make themselves more attractive to the cleaners," he explained. "And they systematically circle for about 45 minutes at speeds lower than one meter per second." This is about half the speed at which the sharks usually swim. These reefs, which are habitats for cleaner wrasses - as the industrious little fish are known - are probably vital for the sharks' health.
Picture Perfect
17 March 2011 - Adult monkeys recognise photographs of their friends, according to scientists.In an experiment, untrained Barbary macaques showed interest in the photos and spent more time scrutinising pictures of unfamiliar animals.Juvenile monkeys were fascinated but puzzled by the photographs. They often tried to greet or touch the animal in the image.The findings suggest that the primates learn with age to understand that photos are representations of faces. As well as adding to our knowledge of their intelligence, the findings, published in the journal Animal Condition could also help in future studies of primate behaviour.
Now that we know [that they spontaneously recognise photographs], we won't be limited to working in the lab and training the animals," said lead researcher Professor Julia Fischer, from the German Primate Center and Gottingen University in Germany. "We will be able to study them in a much more natural captive setting, [studying their behaviour] by designing games for them to play."She and her team observed macaques in wildlife park in Rocamadour, south-west France, where the animals are allowed to roam around an open landscape
Manners and Courtesy
16 March 2011 - I liked this piece by Laura King in the Los Angeles Times:
Reporting from Tokyo -- She was elderly and alone, injured and in pain. When the massive earthquake struck, a heavy bookshelf toppled onto Hiroko Yamashita, pinning her down and shattering her ankle. When paramedics finally reached her, agonizing hours later, Yamashita did what she said any "normal" person would do, her son-in-law recounted later: She apologized to them for the inconvenience, and asked if there weren't others they should be attending to first.
The worst earthquake in Japan's recorded history left a trail of blazing buildings, inundated coastal communities, wrecked roadways and potentially unstable nuclear power plants. But it barely made a dent in the implacably Japanese trait of exhibiting concern for others even in the worst of circumstances.
In Tokyo and its suburbs, the quake knocked out much of the usually clockwork-reliable public-transportation system. Yet when trains finally appeared on a few crucial routes, the queue was as orderly as on any mundane commuting day. Once aboard, people sat quietly, gazing at their cellphones in hope of an elusive signal. “It would be uncivilized to try to push and shove, and what good would it do anyway?” said Kojo Saeseki, helping his wife onto a crowded train on the city’s outskirts.
The Japanese language is full of ritual apologies, uttered so often as to become almost meaningless: I am about to make a nuisance of myself — please excuse me! Some of this is a matter of mere formality. But at a time of crisis, such politesse can be the glue that holds the country together. Even though Friday's magnitude 8.9 quake was shocking and discombobulating, few would imagine burdening a stranger with their anxieties.

Zion
15 March 2011 - From the BBC: Iran has indicated it will attend the 2012 Olympics in London, despite complaining that the Games logo resembles the word "Zion".Last month the Iranians complained to the International Olympic Committee and called for the graphic to be replaced. They objected on the grounds that its resemblance to the word Zion - a Biblical term for Israel - was racist.But now the Iranian-backed Press TV has quoted an official as saying Iranians will "participate gloriously". The report by Press TV quotes the secretary of Iran's Olympic organising committee, Bashram Afsharzadeh, as saying: "Our decision, to partake [in the] Olympic Games, has nothing to do with the UK politicians. "We will make co-ordination with officials of the International Olympic Committee and we will participate and play gloriously in London Games." In its original letter to the IOC, Iran had called for the Games logo to be withdrawn and its designers "confronted".There was also a suggestion that Iranian athletes would be told not to attend. At the time, IOC president Jacques Rogge told BBC Sport: "No, it can't be serious. We will quietly reply, telling [Iran] the logo has nothing to do with racism or any political connotation."
Obama - The Icon
14 March 2011 - The Associated Press has sued several retailers including Urban Outfitters for the unauthorised use of the Hope image created by artist Shepard Fairey. Artist Fairey used an AP photo without permission to create the image, and was sued by the news agency for violating copyright. That case was settled. AP argues that using the image on T-shirts is wilful and blatant violation of the copyright of the photo.A spokesman said that using photos for free devalued the work of journalists. The news agency filed lawsuits against Urban Outfitters, Nordstrom and Zumiez seeking unspecified damages. A Nordstrom spokeswoman said in a statement that the firm was aware of the lawsuit. Representatives of the other retailers have yet to respond, AP said. In a statement, AP spokesman Paul Colford said: "When a commercial entity such as these retailers, or the company that sold the shirts to them, gets something for nothing by using an AP photo without credit or compensation, it undermines the AP's ability to cover the news. "It devalues the work that our journalists do, often in dangerous locations where they may literally risk life and limb to cover a story."
Drink Up
13 March 2011 - Drinking a glass or two of alcohol a day could protect you from developing dementia as you get older, a new Published March 2 in the journal Age and Ageing, German researchers revealed that light and moderate drinkers of any type of alcohol were 29 percent less likely to develop any kind of dementia than heavy drinkers or teetotalers. Good news for Alzheimer's disease too: light and moderate drinkers also had 42 percent less chance of developing the disease than heavy drinkers and those who abstained completely. Light drinkers in the study drank about one drink a day, or 10 grams of wine, beer, or liquor. Moderate drinkers imbibed two drinks per day. Research published last October in the journal Neurology also found that walking just 9.5 kilometers (six miles) a week may keep your brain sharper as you get older. Walking may protect aging brains from growing smaller and, in turn, preserve memory in old age.
