 A group of scientists affiliated with the SuperNova Legacy Survey
(SNLS) have found startling evidence that there is more than one kind
of Type Ia supernova, a class of exploding stars which until now has
been regarded as essentially uniform in all important respects.
Supernova SNLS-03D3bb is more than twice as bright as most Type Ia
supernovae but has much less kinetic energy, and appears to be half
again as massive as a typical Type Ia.

 Using a high-powered electromagnet, Brown University physicists Karine
Guevorkian and James Valles have created a topsy-turvy world for the
single-celled paramecium. They have managed to increase, eliminate and even
reverse the effects of gravity on the tiny protozoan, changing its swimming
behavior and indirectly measuring its swimming force.

 Astronomers have used a pair of pulsars orbiting
each other, found with CSIRO’s Parkes telescope in 2003, to show that
Einstein’s theory of general relativity is correct to within 0.05% –
the most stringent limit to date. They
also hope to be able to use the two pulsars to determine the exact
nature of the matter that pulsars and other neutron stars are made of.

 Particle Acceleration by Stimulated Emission of Radiation (PASER for Short), a sort of particle analog of the laser process, has been demonstrated, for the first time, by a team of physicists from the Technion-Israel Institute of Technology using the accelerator facilities at the Brookhaven National Lab.
