As much as 90 percent of the universe is made up of matter that is evident to us only by its gravitational effects.  In search of this "dark matter," researchers in Rome and Beijing have reported evidence for a theorized type of dark matter called a WIMP, a weakly interacting massive particle.  This particle was said to be at least 50 times more massive than a proton yet so non-interactive with ordinary matter that a billion might pass through your body every second without a trace.  Another research team disputes these findings.  This group, representing 10 institutions including Berkeley Lab, reports "the world's best discrimination in the search for dark matter."  Their findings appear "incompatible" with the reported WIMP sighting.

According to theory, in the beginning, for a brief instant after the Big Bang, the dominant state of matter in our universe was a soup of sub-atomic particles known as quarks and gluons.  From this primordial soup -- scientists call it a "quark-gluon plasma" -- ordinary matter as we know it today came about.  Quark-gluon plasma is a theoretical lynchpin of nuclear science, yet it has never been seen or detected by humans.  Several scientific collaborations currently are underway, seeking to recreate this primordial soup.  Now, with an announcement out of Europe, the hunt for the quark-gluon plasma is heating up.


For microscopy, the DeepView Internet channel is poised to revolutionize collaborative experiments. In astronomy, researchers are devising a common language for communicating with all robotic telescopes. Together, these developments hasten the era of online experimentation.

The migration of nanotechnology from the lab to the marketplace has hastened with the development of rod-shaped semiconductor nanocrystals.
