Nice to Sniff You: A new Weizmann Institute study found that people sniff their hands twice as much after a handshake. Research student Idan Frumin and Prof. Noam Sobel the Neurobiology Department suggest one of the reasons for this ancient custom may provide people with a socially acceptable way of checking out each other’s odors.

This 3 minute video tells the story of Weizmann Institute researcher Dr. Nachum Ulanovsky who is using bats to explore the brain's ability to locate in space. The brain areas instrumental in this skill are essential for short-term memory. Produced by the Department of Resource Development.

To understand how bats locate individual trees night after night, scientists attached tiny GPS devices to the bats in the first-ever, comprehensive, GPS-based field study of mammal navigation. The researchers collected data as the bats took flight each night from a cave near the Israeli city of Beit Shemesh. These bats flew in a straight line at speeds of 40 km an hour and more -- up to 60 kmh -- at elevations of hundreds of meters, to trees that were about 12 to 25 km from their cave.

How do long nerve extensions get a crucial molecule to an injury site in time? Weizmann Institute findings may help point the way toward better treatments for nerve damage and aid in finding ways to speed up the repair. http://wis-wander.weizmann.ac.il/locally-produced-proteins#.UbBPoEBHLXI

What does courage look like in the brain? Weizmann scientists have discovered brain regions and activity patterns that correlate with choosing to overcome fear

Emotional crying is a universal, uniquely human behavior; When we cry, we clearly send all sorts of emotional signals. In a paper published online today in Science Express, scientists at the Weizmann Institute have demonstrated that some of these signals are chemically encoded in the tears themselves. Specifically, they found that merely sniffing a woman's tears -- even when the crying woman is not present -- reduces sexual arousal in men. http://wis-wander.weizmann.ac.il/tears-are-a-turn-off#.UlUZllCnruw

How easy is it to falsify memory? New research at the Weizmann Institute shows that a bit of social pressure may be all that is needed. The study reveals a unique pattern of brain activity when false memories are formed -- one that hints at a surprising connection between our social selves and memory.
