The Genentech laboratory, a subsidiary of Swiss pharmaceutical group Roche has published results of a clinical trial of a new experimental treatment against skin cancer. This would significantly reduce the advanced tumors.
The drug GDC-0449 blocks the protein “hedgehog” which promotes the growth of cancer cells. It was obtained through genetic modification on the CYCLOPAMINE contained in the plant Veratrum californicum. The CYCLOPAMINE inhibits and blocks the ability of renewal of the cancer stem cells.
The trial focused on thirty-three patients suffering from skin cancer. After taking the oral treatment, eighteen patients …

Canada – Every summer, millions of sockeye salmon would reach the waters of the Fraser River in British Columbia, but from the Canadian press, the vast majority of them never arrived.
After three years of closure of the sockeye salmon in the Fraser River, scientists had forecast a massive return of the sockeye salmon this summer. But far from 10 to 13 million specimens expected, only 1.7 million have found the path of river.

Barry Rosenberger, a senior official of Fisheries and Oceans, said that the fish are probably dead when they …

Astronomers from the University of Glasgow have reported that they were able to measure the depth of sunspots. Back in 1769 while studying spots on the surface of the solar disk, a professor at the University of Glasgow, Alexander Wilson said that the sun spots appears to be concave.
In their study, the researchers used data collected by the mission SOHO. This device was launched in 1995, specifically for observing the Sun, and it had succeeded in obtaining the large number of photographs of heavenly body during the peak of its …

Canada – If a woman eats with a man, she will choose a diet less rich in calories than if she eats with a woman, according to the study by Dr. Young of the McMaster university in Hamilton, Ontario.

Sweden – The teams of the Departments of Physiology University of Stockholm and Linköping have successfully created the first artificial nerve cells which can communicate with nerve cells of a man.
Electrical stimulation has long been used to activate nerve signals. Cochlear implants (ie,  surgically implants installed in the inner ear) are an example. This method, if it activates the cells close to the implant, however offers a very average result. Failure to recognize the different types of cells is the cause.

The artificial cell is composed of electrodes inserted in a …
