![]() Bloomington - Apr 07, 2003 Scientists at the Indiana University Cyclotron Facility in Bloomington have made the first unambiguous detection of a rare process, the fusion of two nuclei of heavy hydrogen to form a nucleus of helium and an uncharged pion. NASA Researchers Put New Spin on Einstein's Relativity Theory ![]() Albert Einstein might be astonished to learn that NASA physicists have applied his relativity theory to a concept he introduced but later disliked namely that two particles that interact could maintain a connection even if separated by a vast distance. Researchers often refer to this connection as "entanglement." |
After Heated Debate, Russia Agrees To Fund ISS Flights![]() The International Space Station (ISS) requires an additional funding of 100 million dollars (94 million euros), a Russian space official told the Interfax news agency Sunday, while not specifying over what period this sum was needed. All countries taking part in the ISS program "agree that the program is underfinanced," added Sergei Gorbunov, a spokesman for the Russian space and aviation agency, Rosaviacosmos. Nozomi Swings By Earth ![]() The Japanese Mars exploration mission Nozomi launched on July 4, 1998, is now cruising in interplanetary orbit, and on target for a final flyby of Earth ahead of insertion into Mars orbit at the end of 2003. |
Science, Technology Investment Determines Future Of War Might![]() Warfighting effects and what is needed to achieve them drive the Air Force's science and technology program, the deputy assistant secretary of the Air Force for science, technology and engineering told members of Congress on March 27. Fire Scout To Get New Blades ![]() Northrop Grumman Corporation's Integrated Systems sector and subcontractor teammate Schweizer Aircraft Corp. have successfully tested a four-blade rotor upgrade that will increase the payload capacity, speed, range, altitude and endurance of the U.S. Navy RQ-8A Fire Scout vertical takeoff and landing unmanned air vehicle (UAV) system. |
The Nuclear Heart of Planet Earth![]() What would we find if we were to dig a hole all the way down to the centre of the Earth? According to high school science books we would discover a liquid iron alloy core and a smaller solid inner core at the center. For ten years, geophysicist J. Marvin Herndon has presented increasingly persuasive evidence that at the very centre of the Earth, within the inner core, there exists a five mile in diameter sphere of uranium which acts as a natural nuclear reactor. In this extended interview Wayne Smith talks with Dr Herndon about this theory and its implications for planetary science. |
