Does the brain really operate like some kind of extra-complex computer, with logic gates and circuits made of the synapses that connect one neuron to another? In 2009, we wrote: In the future, the interface between brain and artificial system might be based on nerve cells grown for that purpose. In research that was recently…

Is this science writer jazzed that ninth-grade girls from a religious girls’ school in Jerusalem won a space/science contest? You bet your sweet solar-powered spacelab she is! It is not just that these girls beat out a lot of other classes (over 400), or that they break more than one stereotype. They also came up…

“Inclusion bodies – those clumps of protein that are found in the brain cells of Alzheimer’s patients – are, sadly, a product of aging,” says Dr. Maya Schuldiner. “They can form naturally in practically all cells, but when these cells get old, the mechanism for clearing them away starts to fail.” That is not great…

Today’s guest blogger is Idan Frumin, a student in the group of Prof. Noam Sobel in the Neurobiology Department.  Their research on the transmission of odor compounds while shaking hands appears today in eLife. It all started one day after lunch, sometime back in 2011. We sat in the lab’s living room (Yeah, we have…

Get rid of your addictions while you sleep? Weizmann Institute researcher Dr. Anat Arzi is not promising this yet, but she and Prof. Noam Sobel have shown that changing bad habits through sleep conditioning could someday be possible. After just one session in the Neurobiology Department’s sleep lab, volunteers reported smoking on average 30% fewer…

Since mental health problems are estimated to affect some 10% of the world’s population, it stands to reason that if you don’t suffer from depression, anxiety or bipolar disorder yourself, you are probably close to someone who does. So you might be pleased to read about a new finding that could eventually lead to a…

Mice on Camera

Take a bunch of peculiar individuals, put them all together in one setting; film their every move, every second of the day. Sound familiar? Dr. Tali Kimchi is explicit about the resemblance of her experiments to a well-known reality TV show. The difference, of course, is that Kimchi’s subjects are mice. She places large groups…

To attain knowledge, add things every day. To attain wisdom, remove things every day. Lao Tsu Apparently our nervous systems develop according to the Chinese philosopher’s principle of being and not being. As our nerve cells grow, they send out long extensions – axons – throughout the developing tissues. And as they reach out, some…

What’s that Smell?

Weizmann Institute scientists have created a “white smell.” Think about white light or white noise: Each mixes a bunch of different waves together from various parts of the visual or audible spectrum. Those wavelengths combine such that we perceive that unobtrusive light or sound we call “white.” How do smells fit into this scenario? Prof.…

The idea of “seeing the world through the eyes of a child” takes on new meaning when the observer is a computer. Institute scientists in the Lab for Vision and Robotics Research took their computer right back to babyhood and used it to ask how infants first learn to identify objects in their visual field.…
