The “Jaws” from James Bond or Patrick Bateman, the protagonist of “American Psycho” – psychopaths have difficulty feeling compassion. Their behavior is similar to that of people here who have suffered a serious injury at the anterior skull. The reports the University of Haifa in a recent press release.

Scientists have studied 17 people who were diagnosed as psychopathic, and 25 other people on a frontal lobe injury. Each of the subjects had to complete a computer-based test, which the system analyzed in emotion recognition in others and the ability to show compassion. The analysis showed that both had the psychopath group and the group of injury-related difficulties to respond, sympathetically. In comparison, individuals had the two control groups who had no mental disorder or no brain injury, no problems with their empathy.

Psychopaths suffer from a severe personality disorder. They behave extremely anti-social, add to other pain and can not feel pity and compassion.

The fact that many psychopaths are skilled manipulators and to come with finesse and guile to their destination, but it shows that they evaluate their behavior and reactions of others may well. Sometimes they even use that knowledge specifically to harm them.

The hope of the brain researchers aimed at new forms of therapy: “When psychopaths behave like people with a brain injury, they could also benefit from the same treatment options,” says study leader Simone Shamay-Tsoory.

The anti-retroviral therapy could increase the risk of stroke from HIV-infected people. This presumption draw from a study by U.S. scientists.

An increased risk of stroke have HIV-infected people. This emerges from a study by the University of California at San Diego. From 1997 to 2006 dropped words, whilst the number of hospitalizations due to stroke in the United States by seven percent. But in the same period the number of HIV-infected stroke patients increased by 60 percent. With an average age of 50 years, the HIV-infected patients with stroke were also younger than other stroke patients without the infection.

Two possible reasons for the lead scientist for this development. One of them is a side effect of antiretroviral therapy (ART). HIV-infected people to live long must take anti-retroviral agents, to maintain the virus in check and delay the onset of AIDS as long as possible. So far side effects of ART, such as diabetes or lipid disorders were known. Another reason, according to the researchers draw their report in the journal “Neurology” an interplay of several metabolic processes into account. Also, the virus itself could be the cause of stroke. The scientists will now conduct research in this area.

Tears are odorless. Still stuck in them, signaling substances that cause weeping women contribute to men less attractive. This is the result of a study, which presents the Israeli Weizmann Institute of Neurobiology in a press release.

For their experiment, the team gathered around Shani Gelstein the tears of women who considered themselves a sad movie. Then the researchers tested whether men were able to sniff out the difference between tears and a saline solution. Conclusion: An olfactory differentiation could not.

was more surprising that the tears haze still had an effect: When the scientists the men submitted faces of women, which they should differ assign attributes evaluated the tear-trial be men, the women depicted although not as sad as under the influence of the salt solution, but as sexually unattractive.

During the experiment, the researchers measured skin temperature, heart rate and hormone levels of the subjects. And I showed that the sexual arousal of men who sniffed in tears, actually decreased. The value of the sex hormone testosterone decreased. On the basis of brain scans, researchers have noticed that also certain brain regions responsible for sexual arousal, were less active under the influence of tears.

This experiment was part of a double-blind study. Neither the researchers nor the subjects knew during the course of who sniffed tears, and who in salty water.

Has long been known that people – perceive many elements in the body fluids, which contain subtle messages to other members of the species – like most animals. That tears also carry a biochemical message in itself, however, new.

What is the one thing you want more than anything when you have diarrhoea? You want it to stop, obviously. In fact, the sooner the diarrhoea stops the better. Since we all get this condition at some point, usually a couple times every year, finding a good diarrhoea treatment is important. Once you find a product that works fast, and in only one dose, you’ll always want to have some tucked away in the medicine cabinet.

When you get diarrhea, it sometimes feels like you need to find a toilet immediately or else you’ll be having an accident. It’s nothing to be ashamed of, it happens to all of us sometimes. This is not the time, however, that you’ll want to be dashing off to the local chemists for a good diarrhea treatment. You know that if you try, this will be the day you get stuck in traffic and have to get to the loo right away.

Stocking up on a good diarrhea treatment and a few other essential over-the-counter medications is always wise. When you need these items, you won’t feel like leaving your home to buy them. Allergy medicines, aspirins, bandages are all examples of things you should have on hand, one day they will really come in handy. You’ll be really glad that diarrhoea treatment is already in your home, because you can’t leave your home right now.

A lot of sport in childhood and adolescence improves bone density and bone growth. An increased risk of bone fracture is not associated with an increased training. Experts therefore call too much movement at a young age.

A lot of sports in childhood and adolescence improves bone density and bone growth. An increased risk of bone fracture is not associated with an increased training, as Swedish scientists have recently found in a study. “The first 20 years of life determine the bone density of people,” Monika Niehaus also said the Professional Association of Child and Adolescent Physicians. “Above all contribute movements against gravity, such as ball games, running and hopping a positive effect,” says the child and youth care professional.

In the study, during an observation period of four years trained about 800 students in addition to the normal physical education 200 minutes a week running, jumping, rope climbing and ball games. The comparison group, around 1,500 students from neighboring schools have graduated next to the school sports for 60 minutes a week, no training. The result: for intense trained children have improved bone density and bone growth, but that it is more often than the other students came to bone fractures.

Bjarne Löfgren and his team of researchers at Lund University suggest that young people “collect” to 25 or 30 years with lots of exercise and good nutrition as much bone mass should. The bone density that is reached between 20 and 30 Age of its maximum and then drops continuously. “A strong bones in old age is more stable bone” says Niehaus.
