August 22 Geniuses Probably Do Exist I always doubt if there are any real geniuses exist in the world because I have never seen one. But Terence Tao, who was one of the four mathematicians awarded the Fields Medal this year, probably was a real genius if this description were true: "Tao's genius at mathematics began early in life. He started to learn calculus when he was 7, at which age he began high school; by 9 he was already very good at university-level calculus. By 11, he was thriving in international mathematics competitions. Tao, now 31, was 20 when he earned his Ph.D. from Princeton University, and he joined UCLA's faculty that year. UCLA promoted him to full professor at age 24."

August 05 An Evidence of Neural Circuits Contributing to Behavior Diacetyl is an attractive odorant to the worm C. elegans. Is this attraction behavior due to the odorant receptor or the olfactory neurons? Diacetyl is detected by the receptor ODR-10, which is expressed in the AWA neurons; while the repulsive odorant 2-nonanone is detected by receptor in the AWB neruons. When ODR-10 is transgenically expressed in the AWB neurons, the animal shows repulsive behavior to diacetyl, providing an evidence that neurons contribute to animal's behavior.
