New interactive features on NASA's Global Climate Change Web site give the public the opportunity to "fly along" with NASA's fleet of Earth science missions and observe Earth from a global perspective in an immersive, 3-D environment. 

Developed using a state-of-the-art, browser-based visualization technology, "Eyes on the Earth 3-D" displays the location of all of NASA's 15 currently operating Earth-observing missions in real time. These missions constantly monitor our planet's vital signs, such as sea level height, concentration of carbon dioxide in our atmosphere, global temperatures and extent of sea ice in the Arctic, to name a few.

Want to be fearless?   Create an army of super soldiers?   A limited test case may be on to something.  

A team of Dutch researchers led by Vici-winner Merel Kindt at Universiteit van Amsterdam has successfully reduced the 'fear response' - they weakened fear memories in human volunteers by administering the beta-blocker propranolol.   Most interestingly, the fear response does not return. 

Can fear be deleted?
