While not primarily useful for telling the time, nuclear clocks could allow scientists to test humankind's fundamental understanding of how reality works.
The RNA molecule is commonly recognized as messenger between DNA and protein, but it can also be folded into intricate molecular machines. An example of a naturally occurring RNA machine is the ribosome, that functions as ...
An advanced imaging-based method from scientists at Scripps Research offers a new way of studying mitochondria.
Whether the light in our living spaces is on or off can be regulated in everyday life simply by reaching for the light switch. However, when the space for the light is shrunk to a few nanometers, quantum mechanical effects ...
Imagine going for an MRI scan of your knee. This scan measures the density of water molecules present in your knee, at a resolution of about one cubic millimeter—which is great for determining whether, for example, a meniscus ...
Humans have been mixing metals to create more useful materials for thousands of years. The Bronze Age, which started around 3300 BC, was characterized by the use of bronze, an alloy of copper and tin which is stronger than ...
To the untrained eye, a cryo-electron tomogram looks more like traces in sand than the detailed snapshot of a cell it is.
At the end of 2022, researchers at Lawrence Livermore National Laboratory announced they had observed a net energy gain through nuclear fusion for the very first time. This monumental milestone toward fusion energy represents ...
The moon has been considered extremely reductive since the Apollo era, as estimated by the low ferric iron content in lunar samples returned in the 1970s. In addition, it has long been a mystery whether a large amount of ...
All life is made up of cells several magnitudes smaller than a grain of salt. Their seemingly simple-looking structures mask the intricate and complex molecular activity that enables them to carry out the functions that sustain ...
