Definition of 'Dog Years' Not as Simple as Multiplying by 7

Mapping changes in the genome over time, researchers have developed a new formula to compare dog age with human age -- and it's not as clear-cut as every dog year equals seven human years.

Animal Tests Point to Possible Path to Ultrafast Insulin

An experimental ultrafast-acting insulin could work four times quicker than current fast-acting formulas, researchers say.

For the study, the researchers focused on a form of insulin called monomeric insulin. Though its structure should, in theory, allow it to act faster, monomeric insulin is too unstable for practical use, so the Stan...
