John P. Millis, PhD for redOrbit.com - Your Universe Online Protons, neutrons, and electrons – it is these tiny particles that make up most of the normal matter (that is, non-dark matter) in the Universe. Yet it is another, nearly massless particle that may turn out to be the most revealing about the nature of the cosmos. The neutrino plays a crucial role in nuclear processes such as fusion. But because of its small mass and neutral charge, it is very difficult to measure and study...

Predicting Solar Storms

Lee Rannals for redOrbit.com - Your Universe Online Predicting solar flares still remains a hit-or-miss task for scientists, but new research may shed more light on helping to predict just when the events could occur. Researchers discovered a new method to predict solar flares more than a day before they occur, which could help provide advanced warnings to protect satellites, power grids and astronauts. As the sun transitions into "solar maximum" next year, more solar activity is...

Using one of the most sensitive neutrino detectors on the planet, an international team including physicists Laura Cadonati and Andrea Pocar at the University of Massachusetts Amherst are now measuring the flow of solar neutrinos reaching earth more precisely than ever before. The detector probes matter at the most fundamental level and provides a powerful tool for directly observing the sun´s composition. Pocar, Cadonati and colleagues report in the current issue of Physical Review...

Researchers from the Institute for Corpuscular Physics (IFIC) and other European groups have studied the effects of the presence of dark matter in the Sun. According to their calculations, low mass dark matter particles could be transferring energy from the core to the external parts of the Sun, which would affect the quantity of neutrinos that reach the Earth. "We assume that the dark matter particles interact weakly with the Sun's atoms, and what we have done is calculate at what level...

Recent puzzling observations of tiny variations in nuclear decay rates have led some to question the science of using decay rates to determine the relative ages of rocks and organic materials. Scientists from the National Institute of Standards and Technology (NIST), working with researchers from Purdue University, the University of Tennessee, Oak Ridge National Laboratory and Wabash College, tested the hypothesis that solar radiation might affect the rate at which radioactive elements decay...

When researchers found an unusual linkage between solar flares and the inner life of radioactive elements on Earth, it touched off a scientific detective investigation that could end up protecting the lives of space-walking astronauts and maybe rewriting some of the assumptions of physics. It's a mystery that presented itself unexpectedly: The radioactive decay of some elements sitting quietly in laboratories on Earth seemed to be influenced by activities inside the sun, 93 million miles...

SIOUX FALLS, S.D. -- Scientists from around the country will gather in the Black Hills next month to pitch experiments to be performed thousands of feet below ground in an abandoned gold mine. South Dakota is preparing to take ownership of the Homestake Mine from Toronto-based Barrick Gold Corp. (ABX) within a month, and that will allow officials to begin preliminary work aimed at turning a burrowed-out area 4,850 feet below Lead into an underground laboratory. The state's long-term goal is...

Word of the Day
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
