2Experimental quantum simulation of Avian Compass in a nuclear magnetic resonance system显示文摘Avian magnetoreception is the capacity for avians to sense the direction of the Earth's magnetic field. Discovered more than forty years ago, it has attracted intensive studies over the years. One promising model for describing this capacity in avians is the widely used reference-and-probe model where radical pairs within the eyes of bird combines to form singlet and triplet quantum states.The yield depends on the angle between the Earth's magnetic field and the molecules' axis, hence the relative value of yield of the singlet state or triplet state enables avians to sense the direction. Here we report the experimental demonstration of avian magnetoreception in a nuclear magnetic resonance quantum information processor. It is shown clearly from the experiment that the yield of the singlet state attains maximum when it is normal to the Earth's magnetic field, and the experimental results agree with theory very well.Jason Pearson GuanRu Feng Chao Zheng GuiLu Long 2016Science China(Physics,Mechanics & Astronomy)2016,59,12:1
3印度养鸡场:抗生素滥用与超级“耐药菌”显示文摘根据7月20日发表在《环境与健康展望》(EnvironmentalHealthPerspectives)月刊上的一份研究,对印度西北部旁遮普邦的18座各有约5万只鸡的养鸡场的随机检查显示出,三分之二的鸡只都感染了能产生一种特殊酶的细菌,这种酶被称为广谱β-内酰胺酶(ESBL),它能破坏多数青霉素类和头孢菌素类的抗生素。在接受检测的所有肉鸡中,87%的肉鸡含有这种超级细菌,而在蛋鸡中这一比例为42%。Natalie Obiko Pearson Jason Gale 程玺 2017农经2017,0,8:0
