How unruly data led MU scientists to discover a new microbiome By Roger Meissen | MU Bond Life Sciences Center This seminal vesicle contains a newly-discovered microbiome in mice. Some of its bacteria, like P. acnes, could lead to higher occurrences of prostate cancer. | contributed by Cheryl Rosenfeld It’s a strange place to call home, but seminal fluid offers the perfect environment for particular types of bacteria. Researchers at MU’s Bond Life Sciences Center recently identified new bacteria that thrive here. “It’s a new microbiome that hasn’t been looked…

Five things you wanted to know about epigenetics (But were afraid to ask)
What the heck is it, anyway? Epigenetics involves changes in how your genes work. In classical genetics, traits pass from generation to generation in DNA, the strands of genetic material that encode your genes. Scientists thought alterations to the DNA itself was the only way changes could pass on to subsequent generations. So say you lost a thumb to a angry snapping turtle: Because your DNA hasn’t changed, your children won’t be born with smaller thumbs. Classic. Things get way more complicated with epigenetics. It turns out that some inherited changes pass on even though they…
