American animator Ollie Johnston, the last of Disney’s so-called “Nine Old Men”, has died at the age of 95.

Johnston died of natural causes on Monday in Sequim, Washington, according to Walt Disney Studios Vice President Howard E. Green.

Johnston worked on many of the Disney’s classic films, including Snow White and the Seven Dwarfs (1937), Pinnochio (1940), Fantasia (1940), Bambi (1942), and many others.

Johnston worked extensively with his best friend Frank Thomas, a fellow “old man” who died in 2004. The pair met at Stanford University in the 1930s and worked together until Thomas’ death. They retired from animation in 1978, but remained popular speakers and authors about Disney and animation.

“Ollie was part of an amazing generation of artists, one of the real pioneers of our art, one of the major participants in the blossoming of animation into the art form we know today,” said Roy E. Disney.

Johnston devoted much of his retirement to writing and lecturing, but perhaps even more to model trains, a field in which he became considered one of the world’s foremost experts.

Ollie Johnston’s last film was The Fox and the Hound (1981) on which he worked as a supervisor.

In a new study released by the Florida Museum of Natural History on Monday, scientists report spiky skulls evolved at least 25 separate times in different kinds of frogs. The survey was reportedly to be published in Proceedings of the National Academy of Sciences.

Lead author Daniel Paluh, a Ph.D. candidate at the University of Florida, said, “Superficially, frogs may look similar, but when you look at their skulls, you see drastic differences […] Some of the weirdest skulls are found in frogs that eat birds and mammals, use their heads as a shield, or in a few rare cases, are venomous. Their skulls show how strange and diverse frogs can be.”

Some scientists had previously suggested smaller frogs would tend to develop spiky skulls, but that is not what this study reports. Here, researchers evaluated CT scans on 158 different species. They found frogs that had similar ecological niches — meaning they either acquired food in the same way or defended themselves from predators in the same way — tended to develop skulls with similar grooves, spikes, or specialized jaw joints regardless of whether they were ancestrally related to each other.

According to the study, skulls with spikes, grooves or ridges — called hyperossification — often accompanied frogs eating very large prey relative to their own body size. The strong, spacious skulls would allow the frogs to have very big mouths with which to catch birds, rodents, reptiles and other frogs. Spikes sometimes coincided with venomous frogs. The researchers speculated the spikes make it dangerous for predators to hit the frog’s head, as the spikes would break venom sacs under the frog’s skin.

Other bone formations included projections resembling fangs or lower teeth that different species of frogs use for catching prey and fighting. Very few frogs have true lower teeth.

One of the study’s authors, herpetologist David Blackburn, told Discover Magazine the frequency of spiky skulls evolving in otherwise unrelated frogs suggested some deep pattern frogs fell into as circumstances arose: “Somehow, these frogs are turning on some ancient developmental machinery in their DNA.”

Since 1973, when frogs skulls were last comprehensively surveyed, scientists have documented enough new species to double the number known to humans. Also, modern techniques exploit CT scans, of which Paluh and his team made liberal use. The research was part of the oVert project, funded by the National Science Foundation, meant to comprehensively CT-scan over 20,000 vertebrate specimens from United States museums.

Western Australian government authorities say they believe a toxin may be responsible for the recent mysterious death of an estimated 5,000 birds found in the area of Esperance – on the state’s south eastern coastline. Autopsies by toxicologists from the WA Department of Agriculture will test for organochlorins, organophosphates and heavy metals.

Esperance residents first noticed large numbers of dead birds littering their streets and gardens on December 7 last year. Populations of honeyeaters, wattle birds and miners have reportedly been effected.

The birds were being found vomiting and convulsing in bushland and suburban backyards over an extensive area. Department of Environment and Conservation‘s (DEC) nature conservation coordinator Mike Fitzgerald says toxic wetlands near Esperance are the most likely reason for the mass bird deaths.

The DEC says it has failed to figure out the cause of death despite interviewing industry groups, farmers, grain handlers and timber companies about pesticide and chemical use.

Birds Australia, the peak group dedicated to the conservation, study and enjoyment of Australia’s native birds and their habitats, said it had not heard of a similar occurrence. “Not on that scale, and all at the same time, and also the fact that it’s several different species,” chief executive Graeme Hamilton told the Sunday Times. “You’d have to call that a most unusual event and one that we’d all have to be concerned about.”

Mike Fitzgerald said the DEC were looking at something “pretty potent.” “This is not a normal situation. The common thing that we have seen and heard is that the affected birds have an insatiable thirst… If it turns out to be a toxin that is responsible, that will raise more questions because there is no obvious source of exposure.”

The deaths could be a result of a drier than normal winter, causing algal and bacterial blooms in the Esperance Lakes Nature Reserves. Esperance recorded 457mm rainfall in 2006; the average is 620mm.

Initially, health authorities feared a virus, such as the deadly avian bird flu, was responsible. That was quickly ruled out, along with poisoning from bacteria or eating poisoned insects.

The first deaths were reported by Esperance resident Michelle Crisp – who lives close to the worst-affected area. Dozens of native birds began dying in her back yard a week before Christmas. She says she contacted neighbours to discover if they were experiencing the same thing. Mrs Crisp found four dead birds, then 16, then 30 and finally up to 80.

Mike Fitzgerald said that any one of hundreds of toxins could be causing the deaths but so far all leads had not produced any answers.

Los Angeles County prosecutors have brought three felony charges against Stephen Heller for stealing documents from his employer, the law firm Jones Day.

The legal documents discussed the legal ramifications of activist allegations that Diebold Election Systems had used uncertified voting systems in Alameda County elections beginning in 2002. Jones Day represented the controversial electronic voting machine manufacturer at the time. The firm’s lawyers concluded that if such uncertified systems were used, then Diebold could be sued by Alameda County for millions of dollars. The memos also discussed whether the California’s secretary of state had the authority to investigate Diebold.

Mr. Heller has been charged with felony access to computer data, commercial burglary and receiving stolen property. He has pled not guilty.

Blair Berk, Heller’s attorney said, “It’s a devastating allegation for a whistle-blower. Certainly, someone who saw those documents could have reasonably believed that thousands of voters were going to be potentially disenfranchised in upcoming elections.”

In the largest study of its kind, a genetic analysis of 1,168 families with multiple cases of autism has identified genetic links to autism. A previously overlooked stretch of DNA on chromosome 11 implicates a gene called neurexin 1 and increases the evidence for the involvement of neurexins and genes related to glutamate transmission in the brain.

Genetic studies of autism have previously been undertaken; however the new study involves the collaboration of more than 120 scientists from more than 50 institutions representing 19 countries who pooled their data as part of the Autism Genome Project. The findings were published in the Feb. 18 issue of Nature Genetics.

Bob Wright, co-founder of Autism Speaks, a non-profit organization dedicated to increasing awareness of autism, said: “The identification of susceptibility genes will provide profound new insight into the basis of autism offering a route to breakthroughs in new treatments in support of families.” Autism Speaks funded this project in conjunction with the U.S. National Institutes of Health.

Joachim Hallmayer, MD, associate professor of psychiatry at Stanford and chair of the collaboration’s executive committee, explains what is next: “While promising, these results need to be followed up with more refined genetic maps to home in on other specific candidate genes. We also need to look more closely at chromosomal anomalies in large samples of children with autism.” In the paper, researchers caution that the genetic foundation of autism probably involves multiple genes and chromosomal abnormalities.

Autism affects about one in every 150 children, and the CDC has called it an “urgent health concern”. Autism is a developmental disorder which impairs social interaction, communication and features restricted and repetitive interests and activities. Twin studies and other research clearly suggest a genetic basis for the condition. Currently there is no cure for autism, but both behavioral or sensory interventions and drugs can influence the symptoms.

Yesterday, a chilly Amsterdam hosted the Wikimedia Conference Netherlands 2007. Held at the Aristo centre in a suburb of the city and run by Wikimedia Netherlands, the conference was a short train ride from Amsterdam Centraal railway station. The topic, Wikis and Education (Wiki’s en Educatie in Dutch). This was an opportunity for Wikimedians and people in education to come together and see how collaboration could help both.

Wikinews freelance reporter Brian McNeil caught a train from Brussels in Belgium and attended, making an impression on the Wikimedia Foundation chair, Florence Devouard, by spilling her coffee over the first two speakers approximately three minutes before they were supposed to officially open the conference.

China has executed nine people for taking part in July’s ethnic unrest in the western city of Ürümqi, according to a local state news agency.

The official Xinhau news agency reported that the nine were the first of those convicted in the riots to be executed. It said the sentences were carried out with the approval of the country’s supreme court; however, it was not immediately clear where the executions were carried out.

Violence erupted in the Xinjiang regional capital of Ürümqi on July 5, after Uighurs protested the deaths of two Uighur factory workers in a brawl with Han Chinese in southern China’s Guangdong province.

Uighurs said the protests turned violent when police cracked down on the rally. Protesters then attacked ethnic Han people in the regional capital. Two days later, Han Chinese staged revenge attacks. Nearly 200 people are believed to have been killed, but the official toll is much lower.

At least 21 people have been sentenced in connection with the Ürümqi riots, in crimes ranging from murder to arson, robbery, and destruction of property. Twelve people have been sentenced to death.
