Hemoglobin plays role as a chemosensory signal for mother mice to protect offspring

Biochemists in Japan were surprised to discover that the molecule hemoglobin in the blood works not only as an oxygen carrier, but when the blood is spilled as a result of aggression, accident or predator attack, the molecule also acts as a chemosensory signal -; a chemical stimulus picked up by the senses, namely smell in this case -; for lactating mother mice, prompting digging or rearing behavior in them to check the surrounding environment and keep their offspring safe.

Study could help choose the ideal DNA extraction method for microbiome research

Let's face it, we are a results-driven society. Too focused on the outcome, people don't often think about the "how." For instance, did you think about "how" you got to work this morning or did you just get there? In microbiome studies the results are the graphs and the data but the "how," like commuting, is often just part of a routine.
