摘要：Locating sound sources such as prey or predators is critical for survival in many vertebrates. Terrestrial vertebrates locate sources by measuring the time delay and intensity difference of sound pressure at each ear 1-5 . Underwater, however, the physics of sound makes interaural cues very small, suggesting that directional hearing in fish should be nearly impossible 6 . Yet, directional hearing has been confirmed behaviourally, although the mechanisms have remained unknown for decades. Sever...

摘要：Structure-activity relationship (SAR) studies are fundamental to drug and agrochemical development, yet only a few synthetic strategies apply to the nitrogen heteroaromatics frequently encountered in small molecule candidates(1-3). Here we present an alternative approach in which we convert pyrimidine-containing compounds into various other nitrogen heteroaromatics. Transforming pyrimidines into their corresponding N-arylpyrimidinium salts enables cleavage into a three-carbon iminoenamine buil...

摘要：Plants adapt to fluctuating environmental conditions by adjusting their metabolism and gene expression to maintain fitness1. In legumes, nitrogen homeostasis is maintained by balancing nitrogen acquired from soil resources with nitrogen fixation by symbiotic bacteria in root nodules2-8. Here we show that zinc, an essential plant micronutrient, acts as an intracellular second messenger that connects environmental changes to transcription factor control of metabolic activity in root nodules. We ...

摘要：Scientists have long sought to explain how fish can sense the direction of sound, given the challenges that hearing underwater poses. An experimental study testing a variety of models now provides some answers. See p.118
