Greener production of hydrogen peroxide

Chemists report that a carefully tailored alloy of palladium and gold nanoparticles catalyses the direct production of H2O2 while "switching off" the decomposition of the compound.

The atomic structure of nanocrystals

A new imaging technique overcomes the limit of diffraction and can reveal the atomic structure of a single nanocrystal with a resolution of less than one angstrom.

5 million atoms in viral coat

An image indicates that a viral capsid contains some 5 million atoms and it could help scientists find better ways to both fight viral infections and design new gene therapies.

Synchrotron X-rays reveals hidden secrets

By looking for traces of specific elements left in the slab of limestone as the bird decomposed, the researchers hope to uncover heretofore-unseen details of the soft tissue that once surrounded the well-preserved bones.

Roles of DNA packaging protein revealed

Researchers have found that a class of chromatin proteins is crucial for maintaining the structure and function of chromosomes and the normal development of eukaryotic organisms.

Genetic on-off switches

Researchers have developed a set of molecular tools that provide important insight into the complex genomes of multicellular organisms.

Protein hints at gene switch mechanism

The bacterium behind tuberculosis is helping researchers move closer to answering the decades-old question of what controls the switching on and off of genes that carry out all of life's functions.

New class of non-protein coding genes

A team of researchers has uncovered a vast new class of previously unrecognised mammalian genes that do not encode proteins, but instead...

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.
