Is sleep learning possible? A new Weizmann Institute study appearing today in Nature Neuroscience has found that if certain odors are presented after tones during sleep, people will start sniffing when they hear the tones alone — even when no odor is present — both during sleep and, later, when awake. In other words, people can learn new information while they sleep, and this can unconsciously modify their waking behavior. Sleep-learning experiments are notoriously difficult to...

A chemical signal released in the tears of a crying woman may temporarily lower a man's testosterone level if he is within sniffing range of the tears, even though there is no noticeable odor given off, according to researchers from Israel's Weizmann Institute of Science and the Wolfson Hospital near Tel Aviv. It is the first such signal researchers have found in human tears, and it's probably not unique to just women's. Theirs were just the first to be studied. "It's hard to get men to...

Doctors in Israel have developed a unique "sniffing" controller that allows people with severe disabilities to use their noses to write, surf the Web, and even navigate their wheelchairs. The new technology might even be used in the future to create a sort of 'third hand' to assist healthy surgeons or pilots. The device uses a "sniffing technology" that measures pressure changes in the nose from breathing in and out, and then translates these changes to electrical signals. When tested on...

Berkeley -- Though humans may never match the tracking ability of dogs, we apparently have the ability to sniff out and locate odors, according to a new study by scientists from the University of California, Berkeley. Student volunteers presented with odors to one nostril or the other could reliably discern where the odor was coming from, and functional magnetic resonance images of their brains showed that the brain is set up to pay attention to the difference between what the left and right...
