VERY HIGH FREQUENCY RADIATION MAKES DARK MATTER VISIBLE, December 14
The
stars and gas which are seen in galaxies account for only a few percent of the
gravitating material in the Universe. Most of the rest has remained stubbornly
invisible and is now thought to be made of a new form of matter never yet seen
on Earth. Researchers at the Max Planck Institute for Astrophysics have
discovered, however, that a sufficiently big radio telescope could make a
picture of everything that gravitates, rivalling the images made by optical
telescopes of everything that shines.

ALTERNATIVE THEORY OF GRAVITY EXPLAINS LARGE STRUCTURE FORMATION -- WITHOUT DARK
MATTER, December 14 In the standard theory of gravity-general
relativity-dark matter plays a vital role, explaining many observations that the
standard theory cannot explain by itself. But for 70 years, cosmologists have
never observed dark matter, and the lack of direct observation has created
skepticism about what is really out there. Full story at http://www.physorg.com/news85310822.html
PHYSICIST: STARS CAN BE STRANGE, December 14 According to the "Strange
Matter Hypothesis," which gained popularity in the paranormal 1980's, nuclear
matter, too, can be strange. The hypothesis suggests that small conglomerations
of quarks, the infinitesimally tiny particles that attract by a strong nuclear
force to form neutrons and protons in atoms, are the true ground state of
matter. The theory has captivated particle physicists worldwide, including one
of Washington University's own. Full story at http://www.physorg.com/news85336012.html
RESEARCHERS PREDICT A NEW STATE OF MATTER IN SEMICONDUCTORS, December 14
Conventional matter exists in three familiar forms-solid, liquid and gas.
But under special circumstances, quantum theory predicts exotic states of
matter, such as superconductors in which electrons flow with no resistance and
Bose-Einstein condensates in which atoms move as a collective whole. Now, in the
Dec. 15 issue of the journal Science, three Stanford physicists theorize a new
state of matter that may pave the way for electronic devices that dissipate less
energy and generate less heat. Full story at http://www.physorg.com/news85329550.html
NEW TRANSCRIPTION REVEALS NEWTON'S RARE 'THEORY OF EVERYTHING', December 14
A new transcription of Isaac Newton's "theory of everything," providing rare
insight into the scientist's views on nearly all known natural phenomena, is now
available online to scholars around the world, thanks to an Indiana University
research team. Full story at http://www.physorg.com/news85336254.html
