To study small RNA, snippets of RNA that act as switches to regulate gene expression in single-celled creatures, you need lab-cultured microorganisms but a new method of obtaining marine microbe…

MicroRNAs are single-stranded snippets that, not long ago, were given short shrift as genetic junk. Now that studies have shown they regulate genes involved in normal functioning as well as diseases…

A preliminary study on the use of stem cells obtained from a patient's own adipose tissue in the treatment of multiple sclerosis (MS) has shown promising results. The three case studies, described in…

Want to hunt down enemy bacteria?   Look at the sugars on the germs' surface where they start building a 'structure' that helps the microbes resist efforts to kill them. Scientists have…

When want to understand something complex, we make something similar but simpler - a model.  Models in engineering re-imagine complex structures as sticks, strings, and hinges.  Biology…

An unmapped reservoir of briny liquid chemically similar to sea water, but buried under an inland Antarctic glacier, appears to support unusual microbial life in a place where cold, darkness and lack…
