RNA misregulation plays a critical role in the development of many disorders, such as mental disability, autism and cancer. A new technology - called 'Sticky-flares' - developed by nanomedicine experts, offers the first real-time method to track and observe the dynamics of RNA distribution as it is transported inside living cells.
Silicon nanotube-based electrical probes, as ultra-accurate signal recorders with subcellular resolution, may create many opportunities for fundamental biological research and biomedical applications. Here, this technology is used to electrically monitor cellular mechanosensing.
A single drop of blood is teeming with microorganisms - imagine if we could see them, and even nanometer-sized viruses, with the naked eye. That's a real possibility with what scientists call a 'perfect lens'. The lens hasn't been created yet but it is a theoretical perfected optical lens made out of metamaterials, which are engineered to change the way the materials interact with light.
New research shows it is possible to test a candidate material quickly and directly, using off-the-shelf laser technology. The method bypasses the costly, time-consuming step of constructing a prototype solar cell for each material to be evaluated.
