A nuclear-powered 'tunnelbot' to search for life on Jupiter's icy moon Europa

Between 1995 and 2003, NASA's Galileo spacecraft made several flybys of Jupiter's moon, Europa. Several findings from observations of the moon pointed to evidence of a liquid ocean beneath Europa's icy surface. The ocean, researchers believe, could harbor microbial life, or evidence of now-extinct microbial life.

Medium-scale farms are on the rise in Africa. Why this is good news

Driven by population growth and growing land scarcity, most African farm households are witnessing the gradual sub-division of their land. Over time farms are getting smaller and smaller. Today, over 80% of farms in relatively densely populated countries – like Kenya, Ethiopia, Malawi and Rwanda are smaller than one hectare. Because they're so small, few can generate enough income to keep farmers

Climate and vegetation shape wildfire risk in Hawai'i

A new research paper by Dr. Clay Trauernicht is the first study to link climate change to increasing wildfire probability in Hawai'i, and one of the few that looks at this question for tropical regions more broadly. "Fire in tropical ecosystems is driven by cycles of wet and dry periods, which makes it harder to pin to climate change than in temperate areas where longer summertime 'fire seasons' p

The ‘Global Cybercrime Problem’ Is Actually the ‘Russia Problem’

A series of explosive Department of Justice filings—outside the special counsel’s probe—makes clear that Russia is a rogue state in cyberspace.
