Rapid analysis of impurities in solid metallic samples

Thermo Fisher Scientific has developed a unique solution to provide fast and efficient impurity analysis of solid metals, including steels, platinum group metals, gold and other conductive materials.

Structure of TIGAR resolved

Researchers have determined the three-dimensional structure of an enzyme whose presence in the body could help doctors detect cancer earlier or develop more targeted treatments.

DNA shuts off on maturity

The gradual maturing of embryonic cells is apparently due to the shut off of several genes at once rather than in individual smatterings as previous studies have implied.

Structure of key Ebola protein discovered

Researchers are a step closer to finding a way to counter the Ebola virus. A team of scientists has recently solved the structure from a key part of the Ebola protein known as VP35.

New protein function discovery

A group of Dartmouth researchers has found a new function for one of the proteins involved with chromosome segregation during cell division.

Apoptosis signalling complex discovery

Scientists at Burnham Institute for Medical Research have determined the structure of the interactions between proteins that form the heart of the death inducing signalling complex (DISC), which is responsible for triggering apoptosis.

Human regional absorption studies with Enterion and ivMicrotracer in practice

Enterion is a proprietary electromechanical device used by Pharmaceutical Profiles to deliver a drug under test to specific regions of the GI tract.

Viral molecular motor

Researchers have discovered the atomic structure of a powerful "molecular motor" that packages DNA into the head segment of some viruses...

The pathway to mixed-lineage leukaemia

A researcher recently found that in cancer cells the MLL-AF4 protein binds to at least 169 genes, many of which are overexpressed in leukaemia cells and encode hematopoietic stem cell regulators.

Uncovering keys to DNA methylation

Researchers have shed more light on the mechanism that regulates DNA methylation, a fundamental biological process in which a methyl group is attached to DNA.

Potential Alzheimer's treatment

A drug commonly used to treat epilepsy could help clear the plaques in the brain associated with Alzheimer's disease, according to researchers at the University of Leeds.

The evolution of gene regulation

Scientists have shed light on some of the processes that regulate genes and they also have shed light on the evolution of the DNA regions that regulate genes.

Anorexia impairs adolescent bone development

Children and teenagers with even mild cases of anorexia exhibit abnormal bone structure, according to a new study appearing in the December issue of Radiology.

New beliefs about DNA repair

Researchers report the first in vivo experiments on the heterochromatin protein 1 (HP1) family, which sidles up to silent DNA.

Protein tubules free avian flu virus

A protein found in the virulent avian influenza virus strain called H5N1 forms tiny tubules in which it hides the pieces of double-stranded RNA formed during viral infection.

New technique maps nanoparticle growth

Researchers at Rensselaer Polytechnic Institute have developed a measurement technique that will help scientists and companies map...

Lunar prospecting robot

The cool, rocky slopes of Mauna Kea, a dormant volcano that is Hawaii's highest mountain, will serve as a stand-in for the moon as researchers from Carnegie Mellon University's Robotics Institute.

Modelling 3D structure of amorphous materials

Researchers have accurately identified tools that model the atomic and void structures of a network-forming elemental material.

Bacterial crisis command centre

A bacteria cell's 'crisis command centre' has been observed for the first time swinging into action to protect the cell from external stress and danger, according to new research.

Structures of Important Plant Viruses Determined

Flexible filamentous viruses make up a large fraction of known plant viruses and are responsible for more than half the viral damage to crop plants throughout the world.
