Biology meets geometry

Architecture imitates life, at least when it comes to those spiral ramps in multistory parking garages. Stacked and connecting parallel levels, the ramps are replications of helical structures found in a ubiquitous membrane structure in the cells of the body.

A new method simplifies the analysis of RNA structure

Scientists have devised a simple and versatile method, based on the geometry of the RNA molecule, which proved to be highly promising for analysing and understanding the complex interactions that characterise these molecules.

Artificial cells produce real proteins

A living cell, from one point of view, is a sort of sprawling protein factory that can churn out thousands of different proteins to order. Researchers are building on the basic idea of creating 'artificial cells' that might, in the future, enable us to control the production of proteins or other complex biological processes.

Polymeric scaffold recreates bladder tissue

The scaffolds have desirable mechanical and biological properties at the same time, and due to the existence of the bladder tissue at tiny scale instead of cell, they do not require cell extraction or culture.

Team discovers how microbes build a powerful antibiotic

Researchers report that they have made a breakthrough in understanding how a powerful antibiotic agent is made in nature. Their discovery solves a decades-old mystery, and opens up new avenues of research into thousands of similar molecules, many of which are likely to be medically useful.

Biochemists create designer 'barrel' proteins

The scientists have made proteins with central cavities, or channels, running through them. The team believes that these will be useful in designing new protein functions, such as catalysts for breaking down fats, or molecules that span cell membranes to allow new communications between cells.
