BAGANBAZAR GRAPHSource-attributed newsSCIENCE deskMore than six months after Super Storm Sandy hit America’s East coast, Angela Saini reports from New York where scientists, engineers and State officials have gathered to debate how best to prevent future flooding wreaking havoc on that scale again. One option is to build a giant storm protection barrier. But not everyone is convinced that the risk of another Sandy is worth its 10 billion dollar price tag. A cheaper solution is to restore the coastline to its natural State, which would help to slow down the flow of water along the Hudson, should another super storm occur. But something like Sandy is, say sceptics, a highly unusual event - the last time the East Coast was hit with something similar was in 1821. However, with rising sea levels predicted, storms could become more frequent and others insist that the time to act is now, to save the people and homes of New York.
BAGANBAZAR GRAPHSource-attributed newsSCIENCE deskAlthough many animal species cry vocally, the production of tears in response to emotion, both happy or sad, is a trait unique to humans. So why do we cry? What could the evolutionary advantage be to producing tears in response to joy or despair? The science on this topic has been surprisingly sparse until very recently, but now new research seems to be shedding some light on some common preconceptions about the effect and consequences of our tears. Does having a good cry make you feel better, for example, or do women really cry more than men? Researchers in Israel have even discovered that our tears may contain hidden messages triggering surprising responses in those who come into contact with them. Geoff Watts gets the tissues ready as he investigates everything you ever wanted to know about weeping.

Some of the most spectacular Martian landscapes were carved by vast and violent quantities of water in the planet’s past. The Tolkienesque terrain of Iani Chaos is one such place as is the great canyon Ares Valles. Kevin also talks to scientists on the current Curiosity Mars rover mission about water in the deep history of Gale Crater and its central mountain Mount Sharp. The journey concludes with gullies on cliffs and craters, suggesting that water still gushes on the surface of Mars today. Could this mean that life exists on the Red Planet today?(Image: Mars Express spacecraft in orbit around Mars Copyright: ESA- Illustration by Medialab)
