This afternoon we have identified a case of Ebola in a patient in the USA. Both health ministry and public health authorities are working together to give the best care to the patient and to guarantee the safety of all citizens. Officials said other nurses and doctors who work with her would be monitored. Meanwhile, an American cameraman infected with Ebola in Liberia has been flown home and admitted to hospital in the United States, the fifth American to return for treatment. Ashoka Mukpo who was diagnosed early was taken to a bio-containment center.

According to the European Commission’s Institute for Energy, just 0. 3 percent of the Saharan Desert’s intense solar energy can provide Europe with all the electrical power it needs. A company called Nur Energy plans to capture some of it by building a solar plant similar to an Israeli one in the Negev desert that uses heliotropic mirrors. This technology, unlike photovoltaic cells, can generate energy even when the sky is overcast or at night. Thousands of mirrors, spread over 100 square kilometers, will concentrate sunlight to a tower where it heats and melts a special salt.
