That raises the question, if a soldier attaches human or animal-like characteristics to a field robot, can it affect how they use the robot? What if they “care” too much about the robot to send it into a dangerous situation? (more…)

Scientists Define New Limits of Microbial Life in Undersea Volcanoes

A third of Earth’s organisms live in rocks and sediments, but their lives have been a mystery

By some estimates, a third of Earth’s organisms live in our planet’s rocks and sediments, yet their lives are almost a complete mystery.

This week, the work of microbiologist James Holden of the University of Massachusetts-Amherst and colleagues shines a light into this dark world.

In the journal Proceedings of the National Academy of Sciences (PNAS), they report the first detailed data on methane-exhaling microbes that live deep in the cracks of hot undersea volcanoes. (more…)
