beautiful and rare wildlife species, the baluchi black bear has been on the list of the world environmental protection union for many years, and the production of cell lines from this rare bear increases the hope for the revival of endangered wildlife species. to give scientists have succeeded in making a sensor using carbon nanotubes light became very flexible. the researchers created this sensor on a very thin layer that bends easily. in this method, osaka university researchers used carbon nanotubes as optical sensors on a very thin polymer substrate. optical sensors are highly sensitive to a wide range of wavelengths. reinforcement. by using these nanotubes , visible and infrared light can be measured. researchers have identified a type of protein in the immune system that can prevent cancer cells from becoming more aggressive and spreading throughout the body. prevent the body according to the medical press website , australian doctors discovered this protein. it is activated using a combination of new and existing drugs and can inactivate colon cancer cells and keep them in a silent state, as well as
