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…

While You Were Sleeping

“Imagine that you wake up in the morning feeling nothing special, yet you find yourself inexplicably behaving just a bit differently during the day. For example, you take a sniff every time you hear a tone,” says Prof. Noam Sobel. Of course, the people this actually happened to knew they had volunteered for a sleep…

Quasicrystals on Tap

If you followed this year’s chemistry Nobel, you know about the quasicrystal design on the ties made for Prof. Dan Schechtman’s 70th birthday. Even the prime minister was seen sporting one last week. But did you know there is also a quasicrystal scarf? While Prof. Schechtman was getting his white tie and tails ready for…

Do you ever doubt your own memory? New research at the Institute suggests that some of the things we think we remember could be wrong. It seems that our brains are surprisingly willing to exchange a true memory for a false one, just on the basis of friends’ claims. The scientists not only demonstrated just…

In fact, according to new Weizmann research, in adverse conditions we’re more likely to experience slightly different sights or sounds as being the same. The scientists think that this lumping together of similar sensory stimuli may be behind post-traumatic stress syndrome. The experiments showed that volunteers learning to…

Today’s Weizmann Institute news stories include two new papers from the prolific lab of Prof. Yadin Dudai. The first is on a protein that boosts memory in rats. Dudai and his group have been investigating this protein for several years. Previously, they had managed to show that blocking the protein, even for a very short…
