Nothing's more fun like hitting a friend in the back with a potato gun. These 2 guys, apparently had nothing else better to do. To bad that the potato broke in pieces, or he would have been at the hospital right now! Enjoy!

It took place this weekend at the Czech 250cc Grand Prix at Brno. The guy ended up with two ribs broken and a broken pelvis. But I guess it could've been much worse. Ouch! The crash I'm talking about is the second one, so wait for it!

This guy has some guts to even attempt this! Snowboarding with a sail over a mountain road. If there wouldn't of been enough wind/speed on his part he would be in the hospital right now. This is as extreme as it gets!

Npas4: This protein regulates the formation of inhibitory synapses between neurons. The inhibitory activity of neurons is regulated by a particular switch. This is a protein involved in the formation and maintenance of synapses in regulating selectively switching the electrical signal between nerve cells. Its name is Npas4 and was discovered by researchers from the Children's Hospital in Boston this week to publish their study in Nature. In particular, the protein in question is a transcription factor, that is a molecule that can activate or deactivate specific genes. Those which would be linked to Npas4 are more than 270. When the protein is produced in large quantities, we are seeing an increase in the number of inhibitory synapses on the surface of nerve cells. But what induces the production of high levels of Npas4? According to the researchers this is a reaction to excitatory synaptic. "It is as if the same excitement triggers a program to rebalance the brain with inhibition," says Michael Greenberg, coordinator of the study, which continues: "The mice in which the protein is suppressed, in fact, have neurological problems: are anxious, hyperactive and more subject to seizures. " The discovery could help researchers in studying these disorders. Inhibition, in fact, plays an important role in brain development.

The mutation of the gene Alk would be responsible for inherited forms of cancer. Neuroblastoma is a childhood cancer more widespread and aggressive: it attacks the autonomic nervous system during development, forming frequently in tumor masses or into the chest. A study, published in Nature and coordinated by the Children Hospital of Philadelphia (USA), indicates that mutations in the gene anaplastic lymphoma kinase (Alk) would be responsible for inherited forms of the disease. The international group of researchers, including some of the Italian Institute for Cancer Research in Genoa, have collected genetic information of 20 families where the disease was presented in more than one occasion, by analyzing the DNA of 176 people ( of which 49 with neuroblastoma). Eight families, in which at least three individuals suffering from the disease were closely analyzed, possessed the changed Alk gene. The normal role of this gene, which expresses a transmembrane receptor, is not yet understood in depth but, according to previous studies, its alterations increase the risk of developing lymphoma or lung cancer.

Three hours of jogging or 13 of walking per week: according to a U.S. study moderate exercise reduces the risk of breast cancer Being fit, as we know, is not only an aesthetic issue. And now it seems that it is also useful for the prevention of breast cancer. A study of about 65,000 women by researchers at Washington University School of Medicine in St.. Louis and from Harvard University in Boston, just published in Journal of the National Cancer Institute, points out that women practicing sports have a 23 per cent lower risk of developing cancer before the menopause. In particular, it may be important to regularly exercise between the ages of 12 and 22 years. "We have prevention strategies for breast cancer pre-menopausal, but our research shows that physical activity during adolescence and youth, between 12 and 35 years, may be important in the long term reduction of the risk of cancer", said Graham Colditz, professor of Prevention and Control and co-director at the Siteman Cancer Center, Washington University School of Medicine and Barnes-Jewish Hospital. "This is just one more reason to encourage young women to exercise regularly."

A study conducted by an Italian and published on Pnas shows that healthy cells, if required to "diet", have an increased resistance to stress caused by the drugs compared with those ill. Fasting can be a weapon against the heavy effects of chemotherapy. Just as the fight against cancer concentrates its efforts on the so-called magic bullets, drugs capable of selectively target diseased cells from laboratories of the University of Southern California shows a new paradigm: protect healthy cells and then go furiously only against those sick . A team led by biologist Italian Valter Longo, which involved the United States laboratories and the hospital Gaslini of Genoa, has discovered a kind of magic screen that healthy cells (as a result of caloric restriction) have as a defense against chemotherapy. The results of the study appeared on Pnas Early Edition (here a link to the video.)

A study analysis conducted over the past 27 years by British researchers, suggests that some Fans can reduce the risk of developing cancer. A review of studies published over the last 27 years suggests that the anti-inflammatory non-steroidal pharmacy drugs (Fans) such as aspirin could reduce the risk of breast cancer by as much as 20 per cent! In support, some experts of Guy's Hospital in London appeared in a publication of International Journal of Clinical Practice. According to Ian Fentiman, Fans could play an important role not only in prevention, but also as a therapy for women who have developed this type of cancer, combining their use with a hormonal treatment and using them as analgesics.
