NASA hopes that this new rover concept is the way to go into the future and it will lead towards a new way of exploring harsh environments, hopefully on other planets! Very cool! And here's an actual (smaller) project built by NASA:

A really cool video from the Transition Region and Coronal Explorer (TRACE). TRACE is a NASA Small Explorer mission to image the solar corona and transition region at high angular and temporal resolution. Whatever that means. All I can say is that these video of the Sun rulz!

This is NASA WorldWind 1.4 and it makes Google Earth look like child's play. It just takes it to a next level. Besides exploring Earth, you can explore the Solar System's planets just like in Google Earth and see the volcanoes, craters and planet rings. It's plain awesome!

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."

Thanks to special steel plates, the University of Utah is implementing a computer that makes use of terahertz radiation instead of electricity It will be the first computer powered by infrared rays rather than electricity, a super-computer capable of operating at terahertz radiation (far-infrared), the only still unexplored frontier in the electromagnetic spectrum. It is being developed by a group of scientists at the University of Utah. It will probably require ten years of work to be completed. Currently, the group of scientists are making waveguides, the appropriate "channels" that will convey radiation and transmit it from one point to another. To mark a decisive step forward in research, the good results obtained by the use of special sheets of perforated stainless steel which are proving able to lead effectively terahertz radiation (the portion of the electromagnetic spectrum that is between microwaves and infrared, and whose wavelength is between 1 mm and 100 micrometers). As described in the study of Ajay Nahata (which will be published in Optics Express Friday April 18), these sheets will be "the matrix" on which to build the future of computer circuits. According to the surveys conducted so far, in fact, the number of perforations - arranged on a semi-regular on laminate - would maintain control over radiation, not disperse them over the surface of the material. There is still much to be found, for example, the way to drive rays, making them bend, split and reunited later.
