A wallet-friendly electron microscope can work out the structures of huge biological molecules on a budget 1. Cryo-electron microscopy (cryo-EM) uses an intense beam of electrons to reveal fine ...

Within a cell, DNA carries the genetic code for building proteins. To build proteins, the cell makes a copy of DNA, called mRNA. Then, another molecule called a ribosome reads the mRNA, translating it ...

Ribosomes, the cell’s protein-making factories, consume large amounts of energy as they build the proteins that keep cells alive and functioning. When cells experience stress - such as lack of ...

An international team of scientists have used advanced microscopy to image how ribosomes recruit to mRNA. Within a cell, DNA carries the genetic code for building proteins. To build proteins, the cell ...

Cells endure starvation conditions by rewiring their metabolic pathways. For example, in yeast, ribosomes are known to coat mitochondria. Exactly how this behavior promotes survival has remained ...

Cells are tiny, so we use microscopes to see their details. A slide is a thin piece of glass used to hold objects which are examined under a microscope. Peel a thin layer of cells from an onion. Place ...
