Holography, like photography, is a way to record the world around us. Both use light to make recordings, but instead of two-dimensional photos, holograms reproduce three-dimensional shapes. The shape is inferred from the patterns that form after light ricochets off an object and interferes with another light wave that serves as a reference. When created with X-ray light, holography can be an…
In standard settings, the analysis of each DNA modification requires a carefully optimised assay that runs under specific conditions. This increases cost and labour and is a severe limitation to throughput. Now, however, researchers at Stanford University and the Technical University of Denmark have come up with a new method that will enable doctors to make a more precise diagnosis, prognosis and…
Cell division is an intricately choreographed ballet of proteins and molecules that divide the cell. During mitosis, microtubule-organizing centers (MTOCs) assemble the spindle fibers that separate the copying chromosomes of DNA. While scientists are familiar with MTOCs’ existence and the role they play in cell division, their actual physical structure remains poorly understood. Shruthi…

Researchers from Heidelberg University have now developed a new algorithm – a computational procedure – that can extract this connectivity pattern with far greater precision than previously possible from microscopic images of…
When one cell divides into two - that is how all forms of life are propagated - the newly born daughter cells have to be equipped with everything they will need in their tiny lives. Most important of all is that they inherit a complete copy of the genetic information from their mother cell. If this is not the case because a wrong number of chromosomes – on which the genetic information is…

The images detail the flexible structure of the DNA segments, which appear as nanoscale jump ropes.
Touch a hot stove, and your fingers will recoil in pain because your skin carries tiny temperature sensors that detect heat and send a message to your brain saying, "Ouch! That's hot! Let go!" The pain is real and it serves a purpose, otherwise we'd suffer greater injury. But for many people with chronic pain, that signal keeps getting sent for months or years, even when there is no…
