Remove Kodak NTB2 nuclear emulsion from fridge and place at 42oC for around 30-60 mins (until melted).Make up the developer and the fixer and place in the darkroom ready for later (only if developing the same day). The developer should be a 1:1 dilution in water. The fixer is 30% (w/v) of sodium thisulphate.Place slides in a dark box and carry to dark room. Also take a slide rack, tweezers and the emulsion.Switch on ......阅读全文

测测细胞与细胞之间的力？Nature－Protocols发布了新方法
一个活细胞或微生物能施加的力很小，通常不大于几纳米牛顿。相比之下，1纳米牛顿是一支巧克力棒重量的十亿分之一。然而，对生物体和微生物来说，这些力足以允许细胞贴附一个表面或让微生物推动自己朝营养方向发展。 芬兰和德国的科学家现在提出了一种高度适应性的技术——微型移液管力传感器（micropipet
