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.

Scientists create possible precursor to life

How did life originate? And can scientists create life? These questions not only occupy the minds of scientists interested in the origin of life, but also researchers working with technology of the future. If we can create artificial living systems, we may not only understand the origin of life - we can also revolutionize the future of technology.

High-speed evolution in the lab - Geneticists evaluate cost-effective genome analysis

Organisms require flexible genomes in order to adapt to changes in the environment. Scientists have studied genomes of entire populations. They want to know why individuals differ from each other and how these differences are encoded in the DNA. In two review papers they discuss why DNA sequencing of entire groups can be an efficient and cost-effective way to answer these questions.

A new self-assembly process allows the recognition of specific DNA sequences

Researchers have introduced a new approach for achieving a highly selective, recognition of designed nine DNA base pairs. The strategy involves the nickel-promoted assembly of a peptide derived from a transcription factor, and a small molecule equipped with a metal-binding unit that acts as heterodimerizing staple.
