BOULDER, Colo.-Physicists have measured and controlled seemingly forbidden collisions between neutral strontium atoms -- a class of antisocial atoms known as fermions that are not supposed to collide when in identical energy states. The advance makes possible a significant boost in the accuracy of atomic clocks based on hundreds or thousands of neutral atoms.

In a follow-up to a 2006 study, a University of Colorado at Boulder researcher and his colleagues found that an in-class writing assignment designed to reinforce students' sense of identity and personal integrity increased the grade-point averages of African-American middle school students over a two-year period, and reduced the rate at which these students were held back or placed in remediation.

In the immediate aftermath of the 2007 Virginia Tech shootings, students at the university were shocked, confused and wanted answers to simple questions: who was responsible and who were the victims?

It's easy enough for researchers in a laboratory to grow the cells they rely on for their work. Put them in a petri dish with a hospitable fluid, keep them at the right temperature and take care not to expose them to anything that might stunt their growth and soon the tiny specs will be bouncing baby cells, ready for whatever experiments scientist choose to use them for.

Ever wondered how ancient people made their tools and clothing, or how archaeologists go about finding, collecting and analyzing those artifacts?
