Scientists reveal an explosive secret hidden beneath seemingly trustworthy volcanoes
Volcanologists working on remote islands in the Galápagos Archipelago has found that volcanoes which reliably produce small basaltic lava eruptions hide chemically diverse magmas in their underground plumbing systems - including some with the potential to generate explosive activity. These volcanoes might undergo unexpected changes to sudden such activity in the future.

What happens in Vegas, may come from the Arctic?
Ancient climate records from Leviathan Cave, located in the southern Great Basin, show that Nevada was even hotter and drier in the past than it is today, and that one 4,000-year period in particular may represent a true, ''worst-case'' scenario picture for the Southwest and the Colorado River Basin -- and the millions of people who rely on its water supply.

Earliest humans stayed at the Americas 'oldest hotel' in Mexican cave
A cave in a remote part of Mexico was visited by humans around 30,000 years ago - 15,000 years earlier than people were previously thought to have reached the Americas. Excavations of Chiquihuite Cave, located in a mountainous area in northern Mexico controlled by drugs cartels, uncovered nearly 2000 stone tools from a small section of the high-altitude cave. Analysis of the sediment in the cave uncovered a new story of the colonisation of the Americas.
