Unsung hero - researchers produce high-res model of Ndc80 in action

Unless you are in a field of study related to cell biology, you most likely have never heard of Ndc80. Yet this protein complex is essential to mitosis, the process by which a living cell separates its chromosomes and distributes them equally between its two daughter cells. Now, through a combination of cryo-electron microscopy and three-dimensional image reconstruction, a team of researchers have produced a subnanometer resolution model of human Ndc80 that reveals how this unsung hero carries out its essential tasks.

Novel nanotomography method for detailed imaging of fragile bone structures

Scientists working in Germany and Switzerland have developed a novel nano-tomography method, which uses X-rays to allow doctors to produce three-dimensional (3D) detailed imaging of fragile bone structures. This method could lead to the development of better therapeutic approaches to tackle the brittle bone disease osteoporosis, one of the most common disorders among older people.
