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.

Role of prion underestimated

Prion protein, a form of protein that triggers BSE, is associated with other brain diseases in cattle, raising the possibility of a...

New antiviral treatment approach

Viruses dramatically increase cellular metabolism, and existing anti-obesity drugs may represent a new way to block these metabolic changes and inhibit viral infection.

Solid-state NMR moves toward atomic-scale resolution of proteins

A team of researchers has developed unique uses of solid-state NMR spectroscopy. Scientist Live spoke with Dr. Rienstra about his...

Suppressing the hunger hormone

Scientists report success in significantly suppressing levels of the "hunger hormone" ghrelin in pigs using minimally invasive means.

Behind gold's catalytic prowess

Scientist discovers that bilayer clusters of atoms less than a nanometre in dimension are found to be responsible for a vital oxidation reaction.

New cancer, ageing treatments

Researchers have deciphered the structure of the active region of telomerase, an enzyme that plays a major role in the development of nearly all human cancers.

Flu protein suppresses immune system

Researchers have reported a discovery that could help scientists develop drugs to fight the much-feared bird flu and other virulent strains of influenza.
