The taming of the shrew
CH5+, formed by adding a proton (H+) to the well-known methane (CH4) molecule, is the prototype of fluxional molecules. In contrast to common molecules, which are depicted as a rigid structure consisting of balls (atoms) and sticks (chemical bonds), the five hydrogen nuclei in CH5+ can move quite freely around the carbon nucleus.
New strategy to protect healthy gut microbes from antibiotics
Gut microbes promote human health by fighting off pathogens, but they also contribute to diseases such as diabetes and cancer.
