NASA missions let scientists see moon's dancing tide from orbit
30/05/2014
ScienceDaily
Scientists combined observations from two NASA missions to check out the moon's lopsided shape and how it changes under Earth's sway -- a response not seen from orbit before. The lopsided shape of the moon is one result of its gravitational tug-of-war with Earth. The mutual pulling of the two bodies is powerful enough to stretch them both, so they wind up shaped a little like two eggs with their ends pointing toward one another. On Earth, the tension has an especially strong effect on the oceans, because water moves so freely, and is the driving force behind tides.

What happens when you tell a lie? Set aside your ethical concerns for a moment -- after all, lying is a habit we practice with astonishing dexterity and frequency, whether we realize it or not. What goes on in your brain when you willfully deceive someone? And what happens later, when you attempt to access the memory of your deceit? How you remember a lie may be impacted profoundly by how you lie, according to a new study by LSU Associate Professor Sean Lane and former graduate student Kathleen Vieria. The study, accepted for publication in the Journal of Applied Research and Memory Cognition, examines two kinds of lies -- false descriptions and false denials -- and the different cognitive machinery that we use to record and retrieve them.
