About 11,000 years ago, humans made a major shift from hunting and gathering to farming. This change, known as the Neolithic Revolution, dramatically altered our diets.

A bacterial enzyme called histidine kinase is a promising target for new classes of antibiotics. However, it has been difficult to develop drugs that target this enzyme, because it is a “hydrophobic” protein that loses its structure once removed from its normal location in the cell membrane. A bacterial enzyme called histidine kinase is a promising…
Woolly mammoths are evocative of a bygone era, when Earth was gripped within an Ice Age. Current knowledge places early mammoth ancestors in the Pliocene (2.58–5.33 million years ago, Ma) before their populations expanded in the Pleistocene (2.58 Ma–11,700 years ago, kyr). However, as climate changed, their numbers dwindled to isolated populations in modern Siberia…
Terry Husted lives in DeWitt County, a major pathway for migrating birds in central Illinois. After a company submitted plans to construct a wind farm in his area, Husted said he grew worried about the potential for collisions.
