TED: John Kasaona: How poachers became caretakers

In his home of Namibia, John Kasaona is working on an innovative way to protect endangered animal species: giving nearby villagers (including former poachers) responsibility for caring for the animals. And it's working.

BBC: 'Sex' drove fossil animal traits

Several prehistoric creatures developed elaborate body traits in order to attract members of the opposite sex, according to new research.

The purpose of the exaggerated crests and sails found in many fossil animals has long been controversial.

Some scientists said sails helped to regulate body temperature and that head crests helped flying reptiles steer during flight.

Now a study say these traits became so big because of sexual competition.

The findings, by an international team of researchers, is published in the journal American Naturalist.

One of the prehistoric animals looked at by the researchers were pterosaurs - flying reptiles which became extinct at the time of the dinosaurs.

The study suggests the relative size of the head crest compared to the body of the pterosaur was too large for it to have been dedicated to controlling the animal's body temperature or its flight.

Leicester strikes a blow for secularism

An interesting Article by Theo Hobson of the Guardian newspaper.

If a secularist revolution were to emerge in Britain, where would it start? London is too pragmatic to care about such an earnest cause – you can't imagine Boris picking a fight with a bishop. What about the Oxford of Dawkins and Pullman? No: the whiff of royalism and incense lingers in that brainy city. What about more Whiggish Cambridge? No, secularism never grew roots there, despite Francis Crick's best efforts.

Look north – a bit north anyway. Look to Leicester. It's an unlikely choice on the surface: its huge Muslim minority makes it more religious than most cities. But it also has an old secularist tradition - it was here that the first secular society was formed. And this tradition has suddenly flared into life.

The new Lord Mayor is picking a fight with the local Anglican establishment.

Councillor Colin Hall's first move was to appoint fellow secularist campaigners as his Lady Mayoress and his chaplain. The former post went to Eleanor Davidson, who conducts humanist celebrations, and the latter to Allan Hayes, president of Leicester's secular society. Last week Hall refused to attend the traditional cathedral service that welcomes new Lord Mayors. He had asked for the service to be more inclusive of other faiths, and of humanism; he wanted the Lady Mayoress to read a humanist text, and his chaplain to give an address. When the bishop asked to see the sermon in advance, the mayor and his secularist sidekicks pulled out.

Hall has also announced the banning of prayers before monthly council meetings, calling the practice "outdated, unnecessary and intrusive". He added: "I consider that religion, in whatever shape or form, has no role to play at all in the conduct of council business. This particularly applies in Leicester, where the majority of council members, myself included, do not regularly attend any particular faith service." His chaplain has backed the move: "I think it's a good move because saying Christian prayers picks out one particular stance of people in the city. It's rather divisive, in my view."

Bonobos have a secret

In the 1920s Robert Yerkes acquired an unusual ape that he named Prince Chim. Chim was more intelligent, fun-loving, cooperative, emotionally positive and full of life than his chimpanzee companion, Panzee. Chim's vocal behaviour was so prolific and reminiscent of language that Yerkes transcribed it using musical notation. Yerkes had discovered the bonobo.

In the 80s and 90s researchers conducted a study comparing a chimp and a bonobo. The aim was to determine if Yerkes's observations were accurate and if either animal, or both, could learn a human language through cultural immersion rather than instruction. The answer for both apes was yes.

Vanessa Woods writes engagingly of her husband, primatologist Brian Hare, struggling to tackle these questions again. Seemingly ignorant of the earlier work, in 2005 Hare embarked on a mission to find out what differentiates bonobos from chimps. With the Democratic Republic of Congo still mired in the aftermath of war, he travelled to the Lola Ya sanctuary in Kinshasa to study bonobos.

Hare found that bonobos do all kinds of things that chimps are not reported to do: they experience constant genital arousal, become attached to individual humans, think up new ways to engage in sexual, altruistic or cooperative behaviour on an essentially non-stop basis, and they die of broken hearts. In short they are a lot like people, even uncomfortably so - a fact that, ironically, has caused many scientists to ignore them.

Study examines scientists' 'climate credibility'

Some 98% of climate scientists that publish research on the subject support the view that human activities are warming the planet, a study suggests.

It added there was little disagreement among the most experienced scientists.

But climate sceptics questioned the findings, saying that publication in scientific journals was not a fair test of expertise.

The findings have been published in the journal Proceedings of the National Academy of Sciences.

The study's authors said they found "immense" differences in both the expertise and scientific prominence of those who supported the "primary tenets" of latest assessments made by the Intergovernmental Panel on Climate Change (IPCC) and those who were sceptical of the IPCC's findings.

The beautiful and crystalline Blue Marble is now the Stained Blue Marble, created using NASA’s spectacular view of Earth and one of the scenarios for the spreading of BP’s oil, as simulated by the US National centre for Atmospheric Research.

While the NCAR says that their computer simulation shows one of the potential scenarios for the oilpocalypse spread—applying sea currents and typical weather on a neutral dye, not on actual oil—I couldn’t resist overlaying it over the complete image of the Earth. Seeing what could be the extension of this catastrophe in relation to our entire home planet—only 132 days after the start of the deadly flood—gives the whole disaster a complete new dimension.
