According to psychologists in Leipzig, Germany, apes and some birds are able to plan their actions ahead of time.

Psychologists Nicholas Mulcahy and Josep Call at Max Planck Institute for Evolutionary Anthropology say that apes are able to save tools to use at a later time, that will assist them in retrieving food.

The results of the testing are “groundbreaking” and is “a starting point from which we can begin to reconstruct the evolution of the human mind. Apes and jays can also anticipate future needs by remembering past events, contradicting the notion that such cognitive behavior only emerged in hominids,” said Thomas Suddendorf, a psychologist at the University of Queensland Brisbane, Australia.

One aspect of the study is that “our extraordinary abilities of planning for the future did not evolve entirely de novo. Planning for future needs is not uniquely human,” added Suddendorf.

An experiment was performed using bonobos and orangutans. The psychologists placed the apes alone in a room for five minutes. Each of them had a choice of two tools that would allow them to retrieve food and six that would not. The apes were allowed to look at and observe the tools; however, they were not allowed to handle them.

The apes were then taken to a room next door, allowed to take whatever tools they chose, and left alone in the room for at least one hour, while a researcher removed all other tools from the first room. The apes then returned to the first room (where the food was), but the food was not accessible unless they had the right tool to retrieve it.

After repeating the same test several times with each ape, researchers began to see that most apes would begin to use the right tool for the job. Researchers also received similar results even when the apes were left alone in a room overnight where they would sleep.

To make sure that the apes were not associating the tools with the food, they removed the food from the room, but would still give it to the apes if they used the right tool to retrieve it. After this change, most of them did not bring the proper tools, which researchers say confirm that the retrieval is a way of planning for the job.

In experiments using scrub jays (found mostly in the western United States), at the University of Cambridge in the United Kingdom, psychologists have shown that the birds, who usually hide their food to eat later, will hide it again if an enemy bird saw them do it the first time, unless the bird is dominant. The subordinate jay could however, fight the other for the food.

“These results suggest scrub jays remember who observed them make specific caches,” said Joanna Dally who was involved in the study with the scrub jays.

“Together with recent evidence from scrub jays, our results suggest that future planning is not a uniquely human ability, thus contradicting the notion that it emerged in hominids only with the past 2.5 to 1.6 million years,” said Mulcahy and Call in the study.

North Korea test fired a ballistic missile from a submarine yesterday, which landed in the Sea of Japan after traveling approximately 500 km (about 300 miles), according to officials of South Korea and the US.

The missile was fired from a submarine off North Korea’s east coast near Sinpo, officials said, and was reportedly North Korea’s first successful launch after missiles only traveled a small distance in previous tests. The South Korean military accused the North Korean government of using the test to increase military tension during the annual South Korean–US joint military drills, which involve 80,000 South Korean and US troops. North Korea has threatened a preemptive nuclear strike saying the drills were practice for an invasion.

This came on the same day as a meeting between the leaders of China, Japan, and South Korea where, according to Foreign Minister Fumio Kishida of Japan, they “urge[d] North Korea to exercise self-restraint regarding its provocative action, and to observe the UN Security Council’s resolutions”. Japanese Prime Minister Shinzo Abe called the test’s intrusion into Japan’s air defense identification zone “a grave threat to our country’s security.”

Supporters of convicted Australian drug trafficker, Van Nguyen, gathered outside the State Library in Melbourne yesterday to display thousands of messages of opposition to his death sentence.

Callers to talkback radio in Melbourne were overwhelmingly against the death penalty of Nguyen, who immediately admitted his guilt and has cooperated with authorities since being caught smuggling heroin into Singapore. Many called for a boycott of Singaporean products.

25-year-old Nguyen was arrested at Changi Airport in 2002 for carrying heroin and sentenced to death in March. Nguyen claims he carried the 396 grams of heroin strapped to his body in an attempt to pay off his brother Khoa’s $30,000 legal debts.

The Singapore government have announced they will execute Nguyen at dawn on December 2nd. Singapore President S. R. Nathan rejected Nguyen’s clemency four weeks ago. The Melbourne salesman was sentenced to death under Singapore law which determines a mandatory death sentence for anyone found guilty of possessing 15 grams of heroin or more.

Nguyen’s mother was informed on Thursday by registered mail from the Singapore prisons service of the execution date. The letter stated that she should start making funeral arrangements. She will get to see her son in the three days leading up to the execution.

Despite repeated pleas for clemency from many thousands of supporters; religious groups; human rights organisations; the Pope; and the Australian Government – including Prime Minister, John Howard – Singapore officials have said Nguyen’s execution is irreversible.

Mr Howard had argued that Nguyen should be spared, citing mitigating circumstances in his case which pointed to the fact that he was not a serial drug trafficker but had merely been trying to pay off his brother’s debts.

The Victorian Attorney-General, Rob Hulls, says the Singaporean Government has shown no compassion whatsoever in its treatment of Van Nguyen and his family.

“What’s happening is brutal, is inappropriate. I, and the Victorian Government, vehemently oppose the death penalty in any circumstances”, he told ABC Radio. “This is a young kid who has assisted the police all the way… In any other country, he would get a discount in relation to the penalty. But because there is a mandatory death penalty for drug offences in Singapore, this young man may well be executed. It is just grossly inappropriate.”

“Singapore maintains that capital punishment is a criminal justice issue; it is the sovereign right of every country to decide whether or not to include capital punishment within its criminal justice system,” a Foreign Ministry spokesman said.

Singapore argues that there was no international consensus that capital punishment should be abolished. At the most recent meeting of the UN Commission on Human Rights, 66 countries dissociated themselves from a resolution calling for the abolition of capital punishment.

Prime Minister Lee Hsien Loong affirmed Singapore’s position by saying that it has to “stand firm on drugs to protect its citizens from the scourge and to ensure the country does not become a conduit for the trafficking of illicit drugs.”

In reply to a letter appealing for clemency from his Australian counterpart Alexander Downer, Singapore Foreign Minister George Yeo said: “Mr Nguyen imported almost 400gm of pure heroin which would have supplied more than 26,000 doses to drug addicts.”

No one will be permitted to see Nguyen on the morning of his execution. His body will be released to his mother.

Macomb, New York Councilman Steve Burke took some time to speak with Wikinews about his campaign for the U.S. Democratic Party’s 2016 presidential nomination.

Burke, an insurance adjuster and farmer, was elected councilman in Brookhaven, New York in 1979. He left the town after being accused and found not guilty of bribery in the 1980s. Since 1987 he has served as Macomb councilman off-and-on and currently holds the post. From 1993 to 1996 and 1999 to 2002 he worked as chairman of the Democratic Party of St. Lawrence County, New York. Among his many political campaigns, Burke unsuccessfully sought the Democratic Party’s presidential nomination in 1992 and recently attempted to run for U.S. Congress in 2014 but too many of his ballot petition signatures were found invalid. Burke filed with the Federal Election Commission to run for president in the 2016 election on September 18, 2015 and has qualified for the first-in-the-nation New Hampshire Primary.

With Wikinews reporter William S. Saturn?, Burke discusses his political background, his 2016 presidential campaign, and his policy proposals.

According to New Zealand doctor, Doctor Glenn Twentyman from Child, Youth and Family Services at Wiri, South Auckland, hoodies can be a health risk because they block sunlight which causes a vitamin D deficiency, thus weak bones and low energy.

Dr Twentyman said: “It’s the hoodies and the hats and the downward glance of the teenagers, shading your face all the time.”

Dr Twentyman said that every young person that he had tested showed a deficiency of vitamin D. Vitamin D helps vital minerals to be absorbed into the bones. Vitamin D is given to our body from the sun. “A lot of these kids stay away from sunshine. They don’t hang out at the beach or in the bush. Some are into drugs and alcohol and a lot of it is indoor activity and night-time activity. They sleep during the day. They are wearing those hoods and literally they don’t get out in the sun.”

Even though vitamin D is usually absorbed through sun it can also be found in: fatty fish, liver, eggs, full fat milk and butter.

There is an increase in reports of vitamin D deficiency in Oceania. This is most likely because of people trying to cover up because of the higher risk of getting skin cancer due to the ozone hole over New Zealand. His comments come as evidence mounts of increasing vitamin D deficiency in Australasia, partly caused by covering up to avoid skin cancer. Also one student from Tangaroa College, Vincent Wesche, said that he wears a hoodie because “I don’t want to lose my hair,” also referring to rugby player, Carlos Spencer, “Carlos Spencer is starting to lose his hair from the sun.”

Doctor Cameron Grant, from Starship hospital in Auckland, said that he had done a study for four years which found that infants living in Auckland did have a deficiency of vitamin D. “We know that vitamin D deficiency is a health issue in New Zealand. We know that people who are at risk of vitamin D deficiency are for example groups who keep themselves clothed and keep themselves indoors for religious reasons … so his idea is not an unreasonable one.”

Another study also showed that 87% of pregnant woman living in Wellington were vitamin D deficient.

Dr Twentyman said that the people who are most likely to have a vitamin D deficiency are “depressed people and the elderly, such as those kept indoors in rest homes all day.”

Louisiana Republican Governor Bobby Jindal signed a controversial bill hailed by intelligent design supporters, such as the Discovery Institute, and Louisiana Family Forum, a creationist group. Critics of the bill, including several major science organizations, say it allows for the teaching of “creationism” in public schools.

The law, Louisiana Science Education Act, allows teachers to use “supplemental materials” when discussing evolution, but it does not state what the materials would be.

Citing the 1987 Supreme Court ruling in Edwards v. Aguillard, “Louisiana has a long and unfortunate history of trying to substitute dogma for science in classrooms,” said Reverend Barry W. Lynn, an executive director for Americans United for Separation of Church and State. In addition, the American Association for the Advancement of Science, National Center for Science Education, and the Louisiana Coalition for Science opposed the bill arguing it would cause detriment to students’ education by letting in unapproved curriculum.

According to Reuters, Jindal’s office declined to comment on Friday.

Similar Academic Freedom bills have been promoted by the Discovery Institute in other states, but so far they have failed.

Friday, April 8, 2005Professor Perry Bartlett of University of Queensland‘s Brain Institute recommends sex, cryptic crosswords and a good run to stave off dementia.

The researcher, interviewed on Australian ABC radio today [1], said that with 52,000 Australians expected to be diagnosed with dementia by the end of the year, people wishing to ward off the degenerative disorder may benefit from activities which stimulate growth of new cells in the brain, accompanied by mental exercise to select for survival of the resulting crop of new cells.

“Quite prolonged exercise is very good to make new neurones,” said the Professor. “These new nerve cells are really quite vital to our ability to function in the higher brain functions, such as memory and learning. Most of them die. We now know that we can preserve some of them by giving direct stimuli.”

Professor Bartlett explained recent research findings, including those from collaborator Jeffrey D. Macklis [2] at Harvard in the US.

“There are a lot of hormones and changes in blood that go up and down after exercise, and so that may be a lead to some of the chemicals that can drive the production of nerve cells.

“One of the chemicals that seems to promote neurogenesis is prolactin, and prolactin levels are very high in pregnant females. Prolactin levels, by the way, also go up during sex as well. So one could think of a number of more entertaining activities than running in order to regulate the production of nerve cells.

“Perhaps doing something a little more inquisitive or intellectual might be good at selecting their survival. So perhaps one should run a long distance and do the cryptic crossword or something like that,” he said.

Professor Bartlett gave the same suggestions as being potentially helpful in depression, last year in an interview on the ABC Science Show. [3]
