Nucleus-specific X-ray stain for 3-D virtual histology

Histology is used to identify structural details of tissue at the microscale in the pathology lab, but analyses remain two-dimensional (2D) as they are limited to the same plane. Nondestructive 3D technologies including X-ray ...

Genome-wide rules of nucleosome phasing in drosophila

LMU researchers have, for the first time, systematically determined the positioning of the packing units of the fruit fly genome and discovered a new protein that defines their relationship to the DNA sequence.

Plasma from lasers can shed light on cosmic rays, solar eruptions

Lasers that generate plasma can provide insight into bursts of subatomic particles that occur in deep space, scientists have found. Such findings could help scientists understand cosmic rays, solar flares and solar eruptions—emissions ...

DNA dominos on a chip

Normally, individual molecules of genetic material repel each other. However, when space is limited DNA molecules must be packed together more tightly. This case arises in sperm, cell nuclei and the protein shells of viruses. ...

Ancient protein-making enzyme moonlights as DNA protector

Scientists at The Scripps Research Institute (TSRI) have found that an enzyme best known for its fundamental role in building proteins has a second major function: to protect DNA during times of cellular stress.
