The Volcanoes Are Alive with the Sound of Magm
When volcanoes erupt, they create a stunning visual spectacle for anyone watching, but they also emit impressive noises that range from low rumbles to concussive blasts. Some of the sounds are below the range of human hearing, and a new study suggests they can be used to better understand and monitor eruptions.

Biophoton Communication: Can Cells Talk Using Light
A growing body of evidence suggests that the molecular machinery of life emits and absorb photons. Now one biologist has evidence that this light is a new form of cellular communication. One of the more curious backwaters of biology is the study of biophotons: optical or ultraviolet photons emitted by living cells in a way that is distinct from conventional bioluminescence.
