Results: A 24-year-old South African man whose penis was amputated three years ago has undergone the first successful penis transplant ever. Doctors say the man is able to get an erection, ejaculate, and engage in sexual activity with his girlfriend.
Significance: The surgeons from Stellenbosch University in South Africa who performed the operation are calling it a "massive breakthrough." The patient also regained full function of his penis in just three months. The procedure could be a game changer for men wtih penile cancer, as well.
Results: On the whole, narcissism appears to affect men more than women – at least that’s what a recent large-scale study suggests. Researchers from the University at Buffalo School of Management reviewed 31 years of data that included nearly half a million people. What they discovered was that regardless of age or generation, men were regularly found to be more narcissistic than their female counterparts.
Significance: One notable finding has to do with entitlement, which is a sub-division of narcissism. Researchers say that men appear to be more likely to exploit others and to feel more entitled than women. Interestingly, there was no gender gap when it came to vanity and self-absorption.
Study subjects:Over three million people
Results:New research suggests that social isolation significantly predicts risk for premature mortality as well as other well established risk factors. According to a recent study from Brigham Young University, a lack of social relationships can be as threatening to our longevity as obesity.
Significance:“The key point that I hope others will get from this is the recognition that this is an important public health issue,” says lead author Julianne Holt-Lunstad. The news isn't all bad - she adds that the good associated with being socially connected may be just as, if not more, impactful than the risk associated with being isolated.
