Eric Fortune of Johns Hopkins University who studies psychology and brain science began studying South American birds when field biologists reported the birds singing duets. His research is seeking to explain how the brain handles the details of the shared song.
Birds singing duets isn't unheard of, but it's rare and these perform the fastest and most precise songs known, Fortune said in a telephone interview. The birds live in dense bamboo groves in the Andes Mountains in Ecuador.
"Calling it a love song is probably too strong a word," says researcher Eric S. Fortune of Johns Hopkins University in Baltimore. But, he adds, the little wrens shift their heads around and move closer together as they sing.
Fortune thinks it's a test, with the female birds choosing mates based on how well the males can follow cues and keep up with the song.
The females start the song, he said, and the males join in. Sometimes the males will drop out for a bit. He isn't sure if it's a mistake on their part, or they just can't keep up. Indeed, the birds alternate chirps so quickly it can sound like a single bird singing.
"It's as if the birds each sing their own unique part," Fortune explained. If the song had lyrics that went A, B, C, D, the female might be doing A and C while the male did B and D, he said. And, he added, the duet songs vary slightly from place to place.
Reminds me of the mockingjays in the Hunger Games, but this is a picture of a male plain-tailed wren.
Mock Mission to Mars
Mock Mission to Mars
Associated Press November 4, 2011

Moscow’s Institute for Medical and Biological Problems conducted the longest mock space mission
in history. Six men spent 520 days in cramped, windowless compartments to simulate a trip to
Mars. Researchers studied their responses to confinement, stress and fatigue. They communicated with their families and space officials through the internet. They showered only every ten days and ate food similar to what is available on the International Space Station. The scientists stated that the psychological conditions are even more challenging on a mock mission because there would be none of the euphoria or danger of space travel. Halfway through the mission, the men simulated a landing, emerging from the capsule in heavy space suits, planting their flags in a sand covered room.
"If anything, the make-believe nature of this exercise's goal — a simulated Mars walk — would have made it even harder psychologically than a real mission," said James Oberg, a space consultant and NASA veteran. "So the team's success is even more impressive, not less so, because it was 'only a game.'" However, Oberg felt the lack of any female crew members was a flaw in the experiment.
"Aside from the absence of physiological factors such as weightlessness and cosmic radiation, the most glaring shortcoming of this exercise was the all-male composition of the crew," he said. "Psychological studies of frontier life and extended expeditions suggest that aside from specific skills they contribute, the presence of women in an isolated group is a positive, 'civilizing' effect, not a stress-inducing distracting influence."
But the scientists were impressed with the crew’s ability to overcome the language barrier between the three Russian, one Chinese, one French and one Italian-Columbian crew members.
The crew was proud to complete the longest space flight simulation so that "humankind can one day greet a new dawn on the surface of distant but reachable planet." A real trip to Mars is not expected before the year 2030.
It was understandable the crew was looking forward to spending time in the warm sunshine after 17 months of confinement. It is remarkable they were able to get along well for such a long time.
Dogs Trained to Sniff Out Termites
Dogs Trained to Sniff Out Termites
http://news.yahoo.com/sniffer-dogs-join-fight-protect-koreas-heritage-155933193.html
English springer spaniels that were trained to detect explosives and drugs were retrained to sniff out termites. The dogs are being used to save South Korea’s cultural heritage. The dogs were purchased from a police dog training school in the West Midlands by the Samsung Detector Dog Centre. The trainers let the spaniels smell termites, then hid the insects and let them practice searching until they were retrained. If termites can be seen by the human eye, there has already been too much destruction, and most of S. Korea’s historic sites are constructed of wood. Gyeongbokgung, the grandest of Seoul’s five main historic places has 13 main buildings spread over 84 acres. It only took the two spaniels three hours to sweep the whole of Gyeongbokgung. They are trained not scratch the wood but sit rigid to indicate the area of termite infestation. When they make a find, they get to chase a ball as a reward. The Cultural Heritage Administration needs more dogs on the job and the second generation needs to be trained soon. With the climate becoming warmer and more humid, the number of termites in Korea may rise.
Pilots Studied to Understand the Aging Brain
Pilots Studied to Understand the Aging Brain
From HealthDay October 25, 2011 // Published online October 18, 2011 in the journal of Translational Psychiatry
http://news.yahoo.com/aging-brains-decline-may-hinge-gene-130406334.html
Researchers at Stanford University School of Medicine and the Veterans Affairs Palo Alto Health Care System have identified a gene variation that seems to have a major effect on the rate men experience a decrease in intellectual function due to age.
144 pilots over the age of 40 were divided into two groups after taking blood and saliva samples and doing genetic evaluations. The pilots were divided based on having a variant of the BDNF gene, which produces a protein called “brain-derived neurotropic factor.” From previous studies, a variant of the BDNF gene that contains methionine or “met” was thought to increase the rate of intellectual decline.
The pilots were given the flight simulator test three times in two years. The scores in both groups declined over time, but the rate of decline was much steeper in the “met” group. The rate of decline was double in the “met” variant group. MRI scans also found that the “met” variant group showed significant age-related decline in the hippocampus, a brain area that is important to memory and spatial reasoning.
The study suggested one way to keep BDNF levels higher in your brain was to keep physically active. This study is important to help identify people at risk of losing their cognitive functions earlier than normal and to figure out a way to counteract the methionine variant.
A Study to Thwart “Obesity Gene” with Exercise
A Study to Thwart “Obesity Gene” with Exercise
From HealthDay, originally published Nov. 1, 2011 in PLoS Medicine Journal
http://news.yahoo.com/exercise-might-help-thwart-obesity-gene-220407407.html
A new study suggests that people predisposed to be obese can reduce their odds of weight
gain by remaining active. The FTO gene or “fat mass and obesity associated” gene has a 27%
weaker effect on physically active adults. Researchers examined the data of 45 previous studies
with more than 218,000 participants.
The main point is that the genetically susceptible can still prevent weight gain with a healthy
lifestyle. Regular activity like walking the dog, taking the stairs, and doing chores still count.
People don’t have to do rigorous exercise for it to help. One hour of activity five times a week
is beneficial.
Some people that are predisposed to being overweight may feel they are hopeless to fight
obesity. A recent study on the effects of genetic testing showed those people increased their
dietary intake over the next three months, suggesting they felt there was no control. However,
researchers feel this sense of fatalism is misplaced.
According to the U.S. Centers for Disease Control and Prevention, 2/3 of American adults are either overweight or obese and nearly 1/5 of children up to age 19. Obesity increases the risk of diabetes,
heart disease, stroke and certain forms of cancer.
Decreasing obesity even when predisposed by the FTO gene would not only be beneficial for
individual health but also for the health care system. Diseases like diabetes and heart disease
cost the health care system millions of dollars each year.

Teen girl students and steriod use.
The Center for Disease and Control and Prevention has found that teen girls use steroids for body building, sports and more. Researchers found that in three national surveys indicated an increase of anger in teen girls that use steroids. Young female steroid users were also more likely to:
• have had sexual intercourse before age 13
• have been pregnant
• drink and drive or have ridden with a drinking driver
• carry a weapon
• have been in a fight on school property in the past year
• have feelings of sadness or hopelessness almost every day for at least two weeks
• have attempted suicide
Therefore I believe that this Article will help teens see that steroids if there drugs, or whatever, it can really hurt you. As for me I know that these are all bad for me so I see what else it can do to me.

Peer Pressure on Preschool children
Researchers from Max Planck institutes for Evolutionary Anthropology have studied 4 year olds and how there already being peer pressured. In there study, the researchers found that children have made there judjement of something to the judgment of a majority of peers. The researchers did an expirement on a group of preschoolers ,by giving them all a book where 3 had the same and 1 had a different one, the people told the children they were all the same and they believed it. When the children were told something they believed it and dint think one of the books were different and for that point children have been peer pressured even by there peers. From this point I believe many peers will see that they pressure there children, even thought they don’t meen to, and for me now I see how this could be true with peers and start pressure on others.

Teen Suicide Prevention
About 1 million people would die by suicide each year. In the U.S nearly 36,000 people take there own lives, and 4,600 victims are between the ages of 10 and 24, making suicide the third leading cause of death in this age group. A Health Care has been researching how to prevent suicide patients that got discharged from going suicidal again, by putting them in a mental health follow up care. After researching on 181 suicidal youths on giving the patients the choice to either do the mental healths follow up or not? 92 percent have gone with the choice of doing the follow up care and have had positive reactions. In knowing that I believe that this health care can help many suicidal patients and bring the suicidal rate down, and as fore me knowing this I know that if I know someone who wants to become suicidal I can tell them to go to this healthcare.
