    Prof. Nachum Ulanovsky: Using Bats to Light the Way

    This three-minute video tells the story of Weizmann Institute researcher ​Prof. Nachum Ulanovsky, who studies free-flying bats to explore the brain's ability to ​work in three dimensions. His work with bats has considerable implications for human neuroscience.

    Weizmann Global Gathering 2014: Partners in Creativity at Lincoln Center, Prof. Noam Sobel

    Prof. Noam Sobel introduces the sensory into the science and dance program: while all our senses are involved in any experience, it is the brain that lets us smell, or hear, or touch. His studies on the brain mechanism behind the sense of smell could lead to early diagnosis of diseases. His dancers are both mechanical and fluid, conveying the way the brain works – and not.

    Shedding Light on the Secrets of Autism

    The Weizmann Institute’s diverse, creative autism research is exemplified by three recent projects: investigating the immune system-brain development connection, using optogenetics to turn autistic behaviors on and off, and determining the causes of social shyness.

    Your Sense of Smell is Actually Pretty Amazing

    Our noses are a much more powerful tool than most of us realize—more sensitive, in many cases, than the most expensive piece of laboratory equipment. Case in point: If you had happened to cross the University of California at Berkeley campus in the early 2000s, you might have noticed an undergraduate—blindfolded, earplugged, and wearing coveralls, knee pads, and heavy gloves—crawling across the lawn with nose to ground, zigzagging slightly back and forth. Was he rolling a peanut across the campus with his nose as punishment for some arbitrary offense during a fraternity initiation? Was he groveling before more senior fraternity brothers? No. He was following a scent trail laid down by a chocolate-soaked string—and doing it almost perfectly.

    New Israeli Research Into Genomes Sheds Light on Causes of Deafness

    Researchers on the quest to solve the puzzle of what causes deafness got one small step closer with the announcement that scientists at Tel Aviv University and the Weizmann Institute of Science have mapped a certain type of RNA (a molecule essential to the coding and expression of genes) that exists in close proximity to the genes related to hearing.

    Autism and the Smell of Fear

    Autism typically involves the inability to read social cues. We most often associate this with visual difficulty in interpreting facial expression, but new research at the Weizmann Institute of Science suggests that the sense of smell may also play a central role in autism. As reported in Nature Neuroscience, Institute researchers show that people on the autism spectrum have different – and even opposite – reactions to odors produced by the human body. These odors are ones that we are unaware of smelling, but which are, nonetheless, a part of the nonverbal communication that takes place between people, and which have been shown to affect our moods and behavior. Their findings may provide a unique window on autism, including, possibly, on the underlying developmental malfunctions in the disorder.

    Study: Autism Linked with Different Reactions to Chemical Signals

    While humans aren’t as smell-dependent as many other animals, studies have shown we respond differently to others when they’re emitting certain olfactory signals—even if we can’t consciously detect them. In a study published today in Nature Neuroscience, researchers find that men with autism spectrum disorder (ASD) sometimes respond differently to these chemical cues in human sweat than do people without the disorder, indicating that such responses may partly explain the disorder’s symptoms.
