U-M researchers solve a molecular mystery in muscle
The muscle-building abilities of hormones known as insulin-like growth factors (IGFs) are legendary. Just do an online search and you'll find not only scientific papers discussing the effects of IGFs on the cells that give rise to muscle tissue, but also scores of ads touting the purported benefits of IGF supplements for bodybuilding.

Study: Grass, fungus combination affects ecology
Fescue grass covers an area equivalent to 12 million football fields in the US, and a new study by ecologists at Rice University and Indiana University shows that the grass and a symbiotic fungus can affect local ecosystems in significant ways. Study results appearing in the Journal of Applied Ecology show that the genetic identity of an invisible fungus living symbiotically in fescue can alter the surrounding composition and diversity of the plant community.
