An experimental “cold fusion” device produced this pattern of “triple tracks” (shown at right) which scientists say is caused by high-energy nuclear particles resulting from a nuclear reaction. SALT LAKE CITY, March 23, 2009 — Researchers are reporting compelling new scientific evidence for the existence of low- energy nuclear reactions (LENR), the process once called “cold fusion” that may promise a new source of energy. One group of scientists, for instance, describes what it terms the first clear visual evidence that LENR devices can produce neutrons, subatomic particles that scientists view as tell-tale signs that nuclear reactions are occurring. Low-energy nuclear reactions could potentially provide 21 st Century society a limitless and environmentally-clean energy source for generating electricity, researchers say. The report, which injects new life into this controversial field, will be presented here today at the American Chemical Society’s 237 th National Meeting. It is among 30 papers on the topic that will be presented during a four-day symposium, “New Energy Technology,” March 22-25, in conjunction with the 20 th anniversary of the first description of cold fusion.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
