Managing Emotionally Challenging Situations Comes With Age
Researchers from University of Alberta and Duke University have concluded that managing emotional situations really comes with age. They have identified brain patterns that can help older people to control emotion better than younger adults. In people with over the age of 60, the two regions in the brain are increased in activity when emotionally challenging situations were presented. Older people are better able to manage how much attention they should pay to negative situations. Therefore they’re less upset by them.
Rare Foreign Accent Syndrome From Stroke
A woman from southern Ontario Canada, recovering from a rare brain syndrome due to stroke, starts to speak with a different accent, and this is the first reported cases in Canada. This woman’s family noticed the accent change while the woman was recovering from a stroke. Her Ontario accent now sounds like Maritime Canadian English.
Researcher Alexandre Sévigny, a cognitive scientist at McMaster University in Ontario said that this women never visited the Maritimes, nor has she been exposed to anyone with an East Coast accent. Karin Humphreys, a psychologist at McMaster University reported that the woman didn’t notice any changes in her accent. As strange as it sounds, the ongoing research at McMaster University will open a new perspective of FAS.
Revolutioned Brain Surgery
Sicentists from Howard Florey Institute, Melbourne are developing a revolutionized technology to create individualized brain maps to diagnosis diseases and guide the brain surgery. Current coarse maps of the brain’s structure do not allow for differences that occur between people. This brain mapping technology will provide microscopic level investigation of individual brains, and it will be available in the next 2-3 years.
Uncontacted Tribe
This is a video showing men painted red and black are aiming arrows skyward at a helicopter. This is one of the world’s last uncontacted tribes have been spotted and photographed from the air. There are more than 100 uncontacted tribes known worldwide. These tribes simply reject contact with the outside world.
Factors Related to Homosexuality
Homosexuality is mostly influenced by both genetics and environmental factors. According to researchers from Queen Mary’s School and Karolinska Institute in Stockholm, genetics and environmental factors which are specific to an individual (biological processes such as different hormone exposure in the womb) are the important determinants of homosexuality. Finding a single ‘gay gene’/ gene for heterosexual behaviour is influenced by a mixture of genetic and environmental factors, therefore it is very complicated.
The overall study proved that genetics accounted for around 35% of the differences between men in homosexual behaviour and other individual-specific environmental factors are accounted for 64%.
Traffic-Related Pollution Increases The Risk Of Allergy
Road pollution is increasing the risk of allergy and skin diseases among children by more than 50%. Children who live close to major roads and highways are at high risk of developing allergies and atopic diseases. They are exposed to a higher amount of traffic-derived particles, gases, and more freshly emitted high toxic aerosols. The results of this research appeared in the June issue of the American Thoracic Society’s American Journal of Respiratory and Critical Care Medicine.
Coma Is Equal To Daydreaming?
To find out whether brain-damaged patients will regain consciousness, researchers conducted a study on brain-injured patients with a variety of different levels of consciousness. Some part of the brain can stay active even the brain is severely damaged, and this could help to understand the chances of recovery. The “default network” in the brain seems to match the level of consciousness, and it is more active when the brain is not actively working and that links with daydreaming. With the help of default network, there is a 10% fall in normal activity in in minimally conscious patients, while in coma and “persistent vegetative state” patients, it falls by 35%, and no activity in the brain-dead patients.
Researchers believe that activity within the network will help to confirm the level of consciousness, and help the medical team to decide whether or not to treat the patient.

NASA Astronaut Candidate Class,Deadline approaching
For those who dreams about flying into space,there is a chance your dream may come true. NASA is accepting applications for the 2009 Astronaut Candidate Class, those selected could fly to space for long-duration stays on the International Space Station and missions to the moon. Qualifications?..A bachelor’s degree in engineering, science or math and three years of relevant professional experience or extensive experience flying high-performance jet aircraft. NASA said teaching experience, including work at the kindergarten through 12th grade level, is considered qualifying. After a six-month period of evaluation and interviews, NASA will announce final selections in early 2009. You can apply here to be an astronaut. Deadline for accepting applications is July 1.
Phoenix Found Water in Mars
NASA scientists believe that the white substance exposed by Phoenix lander while digging a trench, is ice. Initially in the bottom of the trench a white material is observed, it disappeared later,meaning it must have been frozen water. Phoenix Lander’s lead investigator, Peter Smith said “These little clumps completely disappearing over the course of a few days, that is perfect evidence that it’s ice.” An earlier experiment carried out on Martian soil sample zyielded no evidence of water. The $420 million Phoenix mission’s main objective was to look for water in Mars. Is this the first step towards a human settlement in Mars?

Bad Guys Get More Girls
Bad boys get the most girls,the finding is backed by two new studies. People with antisocial personality traits known as the “dark triad”,self-obsession of narcissism; the impulsive, thrill-seeking and callous behaviour of psychopaths, have a prolific sex life. The finding may help explain why antisocial personality traits exists in the human population. One study was conducted among 35,000 people in 57 countries.
Evolution Of Facial Expression
A research done by Joshua Susskind of University of Toronto, suggests that different changes on the face would lead to different amounts of sensory intake. When fearful objects were shown, subjects breathed in more air, saw a wider field of view, and could visually track targets more quickly.
On the other hand, expression of disgust seems to produce the opposite effect, that is reducing the sensory intake, which means when pinching noses and squinting eyes in disgust, subjects saw and smelled less. This finding supports Darwin’s idea of emotional facial expressions might have evolved for a reason.
Tree From Christ’s Time
The oldest tree ever has been grown by scientists. The new tree was grown from a 2,000-year-old date palm excavated in Masada. The species of tree, called the Judean date, is now extinct in Israel, but scientists are hoping that this plant may help them in medicinal uses.
According to Carbon dating the seeds found at Masada are roughly the time of the ancient fortress’ siege, in A.D. 73. The seeds were found in storage rooms of Jews, and hidden from invading Romans. The Methuselah tree holds the record for the oldest seed to be germinated.
