DNA nanorobots find and tag cellular targets

Researchers at Columbia University Medical Center, working with their collaborators at the Hospital for Special Surgery, have created a fleet of molecular "robots" that can home in on specific human cells and mark them for ...

Stiffening the backbone of DNA nanofibers

An international collaboration including researchers from the NIST Center for Nanoscale Science and Technology and the Universidad San Francisco de Quito, Ecuador have fabricated a self-assembled nanofiber from a DNA building ...

Why jumping genes don't send us into meltdown

A team of researchers, led by academics at The University of Nottingham, has explained why the so-called 'jumping genes' found in most living organisms don't ultimately kill off their hosts, putting an end to a long-standing ...

The swing of architect genes

Architect genes are responsible for organizing structures of the body during embryonic development. Some of them, namely the Hox genes, are involved in the formation of forelimbs. They are activated in two successive waves, ...

Very berry study aims to improve wine quality

A gene expression study of grapevine berries grown in different Italian vineyards has highlighted genes that help buffer the plants against environmental change and may explain the different quality performances of grapevine ...

Molecular VELCRO for chromosome stability

(Phys.org) —A team of scientists at the Friedrich Miescher Institute for Biomedical Research and the University of Geneva has functionally dissected the molecular processes that ensure the stability of chromosomes. They ...

The fight against genome parasites

In the gonads of animals, genome parasites such as transposons pose a serious threat to evolutionary fitness. With their ability to bounce around in the genome, they often cause dangerous mutations. To protect genomic integrity, ...

Unspooling DNA from nucleosomal disks

The tight wrapping of genomic DNA around nucleosomes in the cell nucleus makes it unavailable for gene expression. A team of Ludwig-Maximilians-Universitaet (LMU) in Munich now describes a mechanism that allows chromosomal ...
