digg_url = 'http://www.digg.com/videos_educational/Spit_Art_2'; Well...this a new one to me...a spit artist doing what he knows best: spit art. I don't know if a spit artist has a future but let's hope we'll see more of his wet art. Go, go spit artist. Enjoy.

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 transfer of data will be hundred of times faster than that by radio waves. The promise is made by the first tests conducted by a German institute. Receiving images in Google Earth or photos of the Hubble telescope in real time may soon be reality. A German institute has experienced a communication system based on lasers which will transfer data at a rate one hundred times higher than that possible with radio waves. The technology was developed by researchers from the Fraunhofer Institute for Laser Technology in Aachen on the company's Tesat GmbH & Co. under a project funded by the German Aerospace Center (Dlr).

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."
