For a rough idea of a dog’s physiological age, a popular approach is to simply multiply its actual age by seven, but new research upends this piece of conventional wisdom. Scientists have developed a new molecular tool described as an “epigenetic clock,” which they say offers a more precise picture of a dog’s age in human years by drilling into the rate of molecular changes in their DNA. read more

Soft-bodied robots have numerous desirable qualities, such as the ability to squeeze through gaps, or survive being stepped on. And so far, they’ve typically been manually assembled on a one-off basis. That could be about to change, though, thanks to a new manufacturing method. read more
