Environmental conditions have a much stronger influence on the mix of microbes living in various parts of your body than does competition between species. Instead of excluding each other, microbes that fiercely compete for similar resources are more likely to cohabit in the same individual.

This phenomenon was discovered in a recent study of the human microbiome – the vast collection of our resident bacteria, fungi, and other tiny organisms. (more…)

EAST LANSING, Mich. — A team of researchers led by Michigan State University has discovered an overachieving plant enzyme that works both the day and night shifts.

The discovery, featured in the current issue of Proceedings of the National Academies of Science, shows that plants evolved a new function for this enzyme by changing merely one of its protein building blocks. (more…)

*Cycle enables marine phytoplankton to use carbon and nitrogen from their environment*

Scientists have discovered that marine diatoms, tiny phytoplankton abundant in the sea, have an animal-like urea cycle, and that this cycle enables the diatoms to efficiently use carbon and nitrogen from their environment. (more…)
