Reopening the solar neutrino question
Article Abstract:
New measurements of solar neutrinos have yet to explain why the Sun's output of neutrinos is less than half of what astrophysicists had predicted. This mysterious finding, first made in 1972, was revived when the Soviet-American SAGE collaboration and the multinational GALLEX experiment announced their new results at the International Neutrino Conference in Granada, Spain, in Jun, 1992. SAGE found that the observed neutrino rate is far below what the theorists anticipated. However, GALLEX also failed to find low-energy neutrinos as called for by the proton-proton flux theory.

What is dark energy?
Article Abstract:
The nature of the 'dark energy' that is causing the apparent accelerated expansion of the Universe is the biggest mystery in physics and astronomy. Tests are conducted to determine whether dark energy is simply the rebirth of Einstein's cosmological constant, or whether it might stem from something even weirder. A three-way comparison of data of the expansion rate of the Universe as it changes with a distance with measurements of the temperature fluctuations in the cosmic microwave background and the clustering of galaxies on large scales, is proposed.

Breaking through the lines
Article Abstract:
Plasmas, consists mainly of protons and electrons, and are commonly permeated by magnetic fields. Plasma and field tend to behave as if frozen together and the plasma's particles lend magnetic field lines physical form by gyrating around them, which is like an individual strand in a bowl of spaghetti that is being stirred, the same field line although constantly changing position and shape, always connects the same particles of the plasma.
