And I myself who believed to have a short life because anxious and tending to be a pessimist!
Pessimistic and anxious rejoice now!
A group of German researchers saw that pessimism may lead to longer and healthier life!
Older people who have low expectations for a satisfying future may be more likely to live longer, healthier lives than those who see brighter days ahead, according to new research published by the American Psychological Association.
“Our findings revealed that being overly optimistic in predicting a better future was associated with a greater risk of disability and death within the following decade,” said lead author Frieder R. Lang, PhD, of the University of Erlangen-Nuremberg in Germany.
“Pessimism about the future may encourage people to live more carefully, taking health and safety precautions.”
The study was published online in the journal Psychology and Aging.
To stay on topic, a search of the North Dakota State University has determined that “rethink the good old past days can help to overcome loneliness and anxiety.” It is a kind of “psychological comfort” which is a way to manage and control stressful situations.
No doubt that the research of the ideal partner is done on an aesthetic basis, at least at first glance, because subjectively characteristics affect more than others do.
For example, according to woman preferences, in a man the physical prowess strikes more, like the size of the shoulders and musculature in general, besides the beauty of the face.
But for our ancestors, the prehistoric men, were these same princes worth?
Starting from the fact that our ancestors did not use clothes, a team of Australian biologists wondered if at that time, the male genital organ easily visible, fell within the parameters of choice of a potential partner. It’s to say if penis size interacts with body shape and height to influence male attractiveness.
It’s obvious that going around naked, the sexual organ could be evaluated and taken into account, the same way as other physical characteristics of a male subject.
In particular, the team was asking what role the penis size may have had for women in their partner choice. Given that man is the only primate to have a sexual organs bigger than other, this can be taken into consideration as an element that has been subject of evolution, that is to say that the choices that women did in the past, may have influenced the evolution of the partner, so that those who had a bigger penis was favored to the others. To see whether this kind of evolutionary heritage was still active today, the team of researchers at the University of Ottawa, has analyzed the importance that the penis traits gets in determining the level of a man’s attractiveness.
Using different animated images in 3D, full-size, about male bodies of different height, body shape and size of the penis, coming from a study of Italian men, the researchers recorded the preferences of 105 women chosen for the test.
It came out that in addition to prefer broad shoulders and narrow hips, also the size of the penis had been valued by women as a factor of attractiveness, and that in general the higher dimensions are considered more attractive, although up to certain values. Namely, the extreme dimensions (such as height or size of the penis) were no longer considered as attractive. Therefore, the size of the genital organs helps to determine the masculine appeal, and the study was published in the Proceedings of the National Academy of Sciences (PNAS). These results, furthermore, as authors say, lead to believe that in the past the women’s choices have driven the evolution to promote (genetically) bigger penis in humans, till to reach the existent average size.
Sometimes there are studies that seem to discover the hot water!
I read about a new research from the University of Georgia (UGA) concerning a survey on some students (from sixth grade to twelfth grade in six different school districts) to check the difference in academic performance between those who were already dating.
In summary, the results of the research reveal that students who date during this study period, have worse overall academic performance.
Weird, I was just convinced of the contrary!
In fact, it is well-known that wonks have always been the students who date earlier and more.
Sarcasm aside, I think no need to set up such researches to become aware that a student who begins flirting during adolescence, then will have another thing to think beyond the study.
Basically, an adolescent who begins to date and carry on an affair, only leads us to know that he/she is probably more “mature” than others. Where for “mature” I mean an adolescent who already feels a physical attraction (and not only) to the opposite sex.
Such maturity (including mental one) is the result of various influences, genetic, temperamental, social and environmental, while physical aspect and stage of sexual development also have their own considerable weight. On the other hand, all this is what, from time immemorial, differentiate unattractive/wimp/introvert teenagers from cool/lively/smart peers.
The research also highlights how emotional difficulties, bullying, depression, and anxiety are linked to higher rates of smoking, drinking, and drug use. Also, another recent University of Toronto study showed that children of divorced parents are 13 times more likely to start smoking cigarettes.
It was to be expected! Or were you thinking differently?
As mentioned ahead, family and social environment affect a lot on children’s behavior. I do not believe we’ve to be psychologists to understand it.
All things hackneyed. Researches or studies that may be, they have their cost. So I say, why researchers do not engage in something more useful, like trying to find ways to decrease divorces, bullying, anxiety, and so on and so forth?!
But, it is evidently easier to conduct a research, like those, to have the confirmation of things we already knew.
Molecule miR-335: a valuable aid against tumor development
Continuing discoveries of 2010, Dr. Roberta Benetti with colleagues at the University of Udine, found that some molecules block the proliferation of the tumor. These cells only attack diseased cells and have therefore targeted as a possible cure. In addition, since these molecules are produced directly by the body, are completely natural and do not have side effects. This discovery could be a key in the treatment of cancer, becoming a viable alternative to chemotherapy or radiation therapy, that have many serious side effects.
The study was published in the renowned journal Cancer Research of the American Association for Cancer Research. A statement of the University of Udine says:
‘In particular, this research has for the first time demonstrated that one of microRNA molecules, precisely the miR-335, is directly responsible for the control, the generation and functions dell’onco-suppressor Rb, gene involved in the protection of the development of tumors. In addition, the study shows that the expression of miR-335 affects directly in balancing the delicate balance of protection against tumor development, because it also strikes on the tumor suppressor p53 through an indirect influence, the effects of two basic proteins known to be deregulated in tumorigenesis.”
The research was conducted with the support of the Italian Association for Cancer Research (AIRC), and with the collaboration of Michael Scarola (PhD student), Stefan Schoeftner (an expert researcher Austrian) and Claudio Schneider, Professor of Biology at the University of Udine and director of the National Laboratory of the Interuniversity Consortium for Biotechnology (CIB).
In a message, Dr. Benetti states: “In terms of therapeutic applicability, the study on miR-335 is still far from clinical trials and none of us has ever dared to say that could replace chemotherapy. The steps to evaluate its effects are very long and we are now experimenting on mice. Of course, we followed up the discoveries of 2010, also deepening its role in stem cells and publishing a recent paper in which we find associated with this new miRNA a new pathway which seems especially active in tumors of germinal origin. We really hope to continue in the right direction but we absolutely are not to the point to be able to do promises.”
That said, we are glad that it’s an Italian research and hoped that these clinical trials really give the results that we are all waiting for years, against this disease to which we are powerless and that for centuries continues to claim millions of victims.
Some recent studies on sex show that it improves intellectual abilities and relieves headache’s symptoms.
Italian researchers at the University of Pavia, published a study that associates sex with the capabilities of the brain. By the tests conducted on various groups of couples, those who had a more intense sexual activity showed a greater nerve cells growth, which, as we know, is essential for body and mind’s well-being. This shows that frequent sex reduces stress and facilitate the functioning of the brain and thus of the intellect. These results, published in the German newspaper Berlin Zeitung, is related to the increase in prolactin that occurs during sexual activity and that improves cellular oxygenation in the brain.
These data are consistent with other researches linking sexual activity to physical and mental health. Among them, two Australian studies published in the International British Journal of Urology, whereof one showing that regular and numerous ejaculations reduce the risk of prostate cancer in men, and the other that a sexual satisfaction increases vitality and psychological well-being in women.
A healthy sexual activity is also able to relieve, in a partial or total way, the symptoms of headache, also when it comes to migraine or the worst ‘cluster headache’, as a recent study by the Department of Neurology at the University of Munster has demonstrated, after having analyzed the effects of the sexual activity on various forms of headache in 1,000 patients.
But, sex’s benefits do not end there, because other researches has shown that:
it helps to sleep;
activates the immune system and helps to be in shape;
in women decrease the risk of incontinence and defend the vaginal mucous membranes;
oxytocin and beta endorphins produced during sex, limit the action of stress hormones and this helps to keep our skin young and healthy, also protecting from the harmful effects of smoking and sun. A strong sex activity stimulates the production of oils in our body, helping the skin to stay elastic and hydrated;
in men hearty sex protects the heart and arteries due to higher testosterone production;
