Soon after reproductive and developmental biologist Sudhansu Dey's group at the University of Kansas moved to new quarters at Vanderbilt University in Nashville, Tenn., they began noticing that once well-established results on uterine gene expression and reproductive function in female mice procured from the same supplier, and of the same genetic strain, had become a lot less predictable.

Last year, after 15-year-old Katie Vanderwheele read an article about natural arsenic contaminating the drinking water in Bangladesh, she decided that tackling this global problem was a natural fit for a school science project.

bacteria can be found in every milliliter of human feces, and on a bad day in Reading University's food microbial science unit you can smell every one of them.

The yeast two-hybrid (Y2H) system can pump out vast quantities of data on a genome of any size.

In the largest study of its kind, researchers have shown that 35% of twin pairs have significant differences in DNA-methylation and histone-modification profiles.1 Moreover, the study suggests that gaps in epigenetic profiles widen with age.
