THE MOMENT OF BIRTH

It is known that fathers who have children at older ages are more tolerant, affectionate and spend more time with their children. Now scientists have discovered another benefit came from these men: their children live longer.
Experts have found that elderly men begotten by parents longer telomeres (ends of chromosomes that protect against aging). Researchers measured the length of telomeres in DNA 1779 Filipino young adults and their mothers and fathers led their grandparents' age. The study revealed that telomeres length indicates not only that age was a father when he conceived child, but that age was a grandfather when he conceived the father.
The findings suggest that paternal reproduction delayed lengthening telomeres can lead to future children, so that the latter could provide a longer life.
Telomeres are known as "chromosomal clock" because even major influence aging. Longer telomeres make us biologically young and healthy. Professor Chris Kuzawa, an anthropologist at Northwestern University explained that although with age, telomeres decreases in somatic cells, they become longer in chromosomes in sperm.
Good news for children "autumn leaves" who came into the world in the period from September to November are more likely to get centenarians compared to the rest of us.
Month in which we are born can influence how we develop, both intrauterine and ectopic. New evidence come to show the month in which we are born can affect behavior and genetic endowment, having a major impact on our health.
Previous research has suggested that those born in autumn are more likely to live longer than those born at other times of the year. However, these studies could not demonstrate that the differences between children born in autumn and the other children did not appear due to socioeconomic differences between families.
Now, Leonid Gavrilov and Natalia Gavrilova of the University of Chicago gathered data on 1,500

centenarians born in the United States between 1880 and 1895. They compared data about birth and death with those of their brothers or husbands. Thus, it was found that most centenarians were born in autumn.
For the same period, scientists have monitored a period of one year, all births in the United States and ordered them according to the season. Pin this method, researchers have shown that autumn were born as many children as in any season and that this did not affect the study results.
Most centenarians were born between September and November, the fewest were born in March, May and July. These differences were more pronounced for those born between 1880 and 1889 compared to those born between 1889 and 1895.
The most popular hypothesis that can explain the new findings is that seasonal infections occurring in the first months of life causes long-term damage to the human health, researchers emphasizing the importance of specific infections season. Other possible explanations include seasonal deficiency of vitamins or hormones seasonal variations.
A new study suggests that human life is much longer than chimps or apes, thanks to the fact that "grandmothers" began to take care of grandchildren.
Through a new simulation, scientists have observed that there grandparents who care for grandchildren would double the life of members of a community. Study support the hypothesis grandparents comes to trying to explain why women, unlike female primates and mammals living well beyond their reproductive years. Theory suggests that women live longer just to take care of grandchildren, in order to allow her children to have more offspring. Therefore, families from grandparents who have had a long life have a genetic advantage, allowing her longevity to spread by natural selection.
The study was conducted by anthropologist Kristen Hawkes of the University of Utah. She was inspired to carry out this research Hadzic hunter-gatherer group in Tanzania. Here in postmenopausal women work very hard. "Economic productivity of these women amazed us," said the author.
In principle, these women out of the earth edible tubers, vegetables very strong, a task which, Hadzic women say it is too difficult for children. Statistically, scientists have discovered that a child's health and success depended Hadzic mother's work, but only until it was to have a new baby. After that, strictly related to child health became much work as grandmother.
To test the hypothesis that grandparents play an important role in promoting longevity, Hawkes has developed a mathematical model representing a community of 1,000 females and males, life expectancy similar to that of primates (approximately 20 years). The model can "evolve", forming a long life or lower, depending on conditions. In the study, grandmothers were defined as women over 45 without children able to care for any child in the community. When these women were integrated into the simulation, scientists have found that life has greatly increased. Between 24,000 and 60,000 years, community members had a lifespan of about 40 years.
This is an average life of a hunter-gatherer, said Hawkes. Therefore, researchers assume that climate change and other factors in human history have made the firstborn difficult to cope with food once their mothers preparing for the birth of other children. In this situation, grandmothers, were those who had to take care of first births to provide necessary food.
The weaned child care, grandmas take some of the pressure that presses on the mother, allowing them to make more dumb kids. In this way, several genes were passed from mother to child, and natural selection favor prolonging life.

"Fountain of Youth" was the ideal of many explorers and scientists over the centuries, driven by the desire to discover the secret of youth and extended longevity. Now, a new study appears to have identified a molecule that meets these requirements.
This is buckminster fuleren miracle substance, a molecule composed of 60 carbon atoms arranged in the shape of a geodesic sphere (or soccer ball). Substance architect Richard Buckminster Fuller called because of the similarity between the structure of this molecule and geodesic dome designed by him. Buckminsterfuleren has potential medical applications against cancer and HIV's being used even in body armor.
A recent study in the Université Paris-Sud shows another benefit of this molecule: extending longevity.
The researchers experimented on rats, which were divided into 3 groups. Rats in the first group were fed a placebo, those in the second with olive oil, and those in the third with a combination of olive oil and buckminsterfuleren.
Scientists have discovered that rats in the first group lived on average 22 months, while those in the second they had an average lifespan of 26 months.
The surprise was in rats fed olive oil and buckminsterfuleren: they lived 42 months, almost two times higher than in the control group rats!
Researchers say that the result is because buckminsterfuleren reduce oxidative stress that underlies aging.
"Our results are very important for medicine, paving the way for numerous applications of the derivative, including the anti-cancer therapy in neurodegenerative illnesses and aging," the researchers said in the study published in the scientific journal Biomaterials.
