Video: 'Mapping' the body with single-cell RNA sequencing

While nearly every cell in the body contains identical genetic instructions packaged in DNA, there is flexibility on how that genetic information is expressed and in turn translated through RNA to create proteins, the building ...

Intracellular nanothermometer has unprecedented versatility

Body temperature is a basic indicator of health. Intracellular temperature is also a basic indicator of cellular health; cancer cells are more metabolically active, and thus can have a slightly higher temperature than healthy ...

Single photon emitter takes a step closer to quantum tech

To get closer to quantum technology we need to develop non-classical light sources that can emit a single photon at a time and do so on demand. Scientists at EPFL have now designed one of these "single photon emitters" that ...

Water processing: Light helps degrade hormones

Micropollutants in water often are hormones that accumulate in the environment and may have negative impacts on humans and animals. Researchers of Karlsruhe Institute of Technology (KIT) and Leibniz Institute of Surface Engineering ...

Unprecedented videos show RNA switching 'on' and 'off'

Similar to a light switch, RNA switches (called riboswitches) determine which genes turn "on" and "off." Although this may seem like a simple process, the inner workings of these switches have confounded biologists for decades.

Researchers design holographic lenses based on plasma

Holograms are three-dimensional (3D) images produced by interfering beams of light that reflect physical objects or photographs. In recent years, they were introduced in a variety of settings, for instance to enhance employee ...
