A puzzle piece found in unraveling the wiring of the brain

...sophisticated genetics applied to the brain of the fruit fly, Drs. Sunil Mehta and Hiesinger found a gene named sec15 that is required for nerve cells to make appropriate choices of targets on which to act. The Sec15 protein is part of a protein complex (the exocyst) which is known to be required for secr...

The evolutionary triumph of flower power

... were tested against other gift stimuli, such as a fruit and sweets basket and a large decorative candle. Of the 147 women tested, all those who received flowers responded with a smile; however, there were no smiles from 23 percent of those who got received candles and 10 percent of those who got fruit. Th...

At long last, scientists figure out how plants grow

...a denser, more sculpted look. Auxin also promotes fruit development. In strawberries, for example, auxin produced by the developing seeds promotes the growth of a red and juicy fruit. Another protein called ABP1 (Auxin Binding Protein 1) has previously been shown to bind auxin. But unlike TIR1 and auxin,...

Red delicious, Northern Spy apples have most antioxidants, chemists find

...ples, but which polyphenols are most active in the fruit has perplexed scientists. Tsao and his colleagues used three different laboratory measures to evaluate polyphenol activity in apples that are popular in Canada: Red Delicious, McIntosh, Cortland, Northern Spy, Ida Red, Golden Delicious, Mutsu and Emp...

Remote control flies? Fly behavior controlled by laser light

...found a way to exercise a little mind control over fruit flies, making the flies jump, beat their wings, and fly on command by triggering genetic "remote controls" that the scientists designed and installed in the insects' central nervous systems, according to a new report in the 8 April issue of the journ...

Bugs, even 'bad' ones, can be educationally beneficial, new book says

Researchers Identify Cause of Early Bird Sleep Disorder

...ian rhythm, he added. But follow-on experiments in fruit flies and mice yielded results that are intriguing. When the mutant gene was inserted into the flies, for example, it did the opposite of what was seen in the human family: it lengthened circadian rhythm. Yet in genetically engineered mice, the same...

UI researcher studies deafness in fruit flies, humans

MicroRNAs play a big part in gene regulation - and evolution

...croRNAs have multiple target genes and that even a fruit fly (Drosophila) has up to 14,000 genes that microRNAs could influence. Not intimidated by the challenge, Dominic Grün and his colleagues at New York University's Center for Comparative Functional Genomics tapped into the power of computation to sea...
