    Can You Learn While You're Asleep?

    Presented on NPR's "Morning Edition" and health blog, the research of Weizmann's Anat Arzi – who found that basic learning can take place while we sleep – is getting a lot of attention. Ms. Arzi and colleagues were able to "teach" participants to associate certain sounds with smells.

    Researchers Discover ""White Noise"" of Smell, ""Olfactory White"" reports on new findings from Prof. Noam Sobel's lab: the discovery of ""white smell."" White noise and white light are made up of sound or light waves mixed together; the team found that combining a range of odor molecules produces the same effect. Their work holds promise for neurobiological research.

    Noses Agree When Genes See Eye to Eye

    <em>Scientific American</em> discusses research from Prof. Noam Sobel's lab, where the team found that we each have a unique smell ""fingerprint,"" and that similar odor preferences may indicate a higher degree of genetic similarity. Among other applications, this could be a ""quick and dirty"" method of identifying stronger matches in organ donation.

    Siri Has Nothing on Us: How Do Brain Cells Tell Us Where We're Going?

    The lab of Prof. Nachum Ulanovsky revealed that brain cells can guide us to our destination, even when we can't see it. <em>Scientific American</em>'s Moheb Costandi reports on the research in <em>Salon</em>, also addressing related findings from other institutions and the question of whether the Ulanovsky cells are new types of cells, or represent more flexibility in other cells than previously suspected.

    Bad Smells Impair Learning

    Performance usually improves with practice, but not if training is a rotten time. A new study shows that people's ability to identify noises declines when the sounds are paired with putrid smells–a phenomenon that may allow our brain to detect danger more quickly.

    The Science of Crying

    <em>Time</em> reports on research that investigates why we cry – or don't. Humans are the only animals that cry for emotional reasons, and scientists across the world are investigating the phenomenon, including the Weizmann Institute's Prof. Noam Sobel. His finding that women's tears may inhibit sexual arousal in men garnered global headlines.

    Researchers Are Building a Tear Bank to Better Understand Why We Weep

    Prof. Noam Sobel, who notably found that women's tears reduce testosterone in men, has found a way to preserve and store tears. As <em>Scientific American</em> reports, he is building a cryogenic ""tear bank,"" which will allow researchers worldwide to study the difference between emotional and nonemotional tears, whether tears affect appetite, and more.
