Nanotechnology enables visualization of RNA structures at near-atomic resolution
We live in a world made and run by RNA, the equally important sibling of the genetic molecule DNA. In fact, evolutionary biologists hypothesize that RNA existed and self-replicated even before the appearance of DNA and the proteins encoded by it. Fast forward to modern day humans: science h ... more
Customized programming of human stem cells
Induced pluripotent stem cells (iPS) have the potential to convert into a wide variety of cell types and tissues. However, the "recipes" for this conversion are often complicated and difficult to implement. Researchers at the Center for Regenerative Therapies Dresden (CRTD) at TU Dresden, H ... more
Separating Drugs with MagLev
The composition of suspicious powders that may contain illicit drugs can be analyzed using a quick and simple method called magneto-Archimedes levitation (MagLev), according to a new study published in the journal Angewandte Chemie. A team of scientists at Harvard University, USA, has devel ... more
