New understanding of actin networks

Dynamic networks of growing actin filaments are critical for many cellular processes, including cell migration, intracellular transport, and the recovery of proteins from the cell surface.

Gene therapy can reduce long-term drinking among rodents

Just as the risk of developing alcoholism is strongly influenced by genetic factors, mutations in gene coding - such as the aldehyde dehydrogenase (ALDH2*2) allele - also appear to protect against the risk.

Avalon Explosion shaped early history of multicellular life

Scientists have known for some time that most major groups of complex animals appeared in the fossils record during the Cambrian Explosion, a seemingly rapid evolutionary event that occurred 542 million years ago.

Scientists find missing evolutionary link using tiny fungus crystal

The crystal structure of a molecule from a primitive fungus has served as a time machine to show researchers more about the evolution of life from the simple to the complex.

Sea-cucumber protein may provide methods of preventing the transmission of malaria

Scientists have genetically engineered a mosquito to release a sea-cucumber protein into its gut which impairs the development of malaria parasites, according to research out today (21 December) in PLoS Pathogens.

Scientists identifiy elusive telomere RNA subunit in single cell model

The Stowers Institute's Baumann Lab has identified the long-sought telomerase RNA gene in a single-cell research model.

RNA interference therapy heals growth deficiency disorder in a live animal

A team of Vanderbilt researchers have demonstrated for the first time that a new type of gene therapy, called RNA interference, can heal a genetic disorder in a live animal.

Plant constituent with selective effect on cancer cells

The substance wogonin triggers the death program apoptosis in tumor cells, while it has virtually no effect on healthy cells.

Monkeys have the ability to perform mental addition

Researchers at Duke University have demonstrated that monkeys have the ability to perform mental addition. In fact, monkeys performed about as well as college students given the same test.

Scientists identify and repress breast cancer stem cells in mouse tissue

By manipulating highly specific gene-regulating molecules called microRNAs, scientists at Cold Spring Harbor Laboratory (CSHL) report that they have succeeded in singling out and repressing stem-like cells in mouse breast tissue - cells that are widely thought to give rise to cancer.

Researchers spearhead key genome initiative

The complete collection of genes - the genome - of a moss has been sequenced, providing scientists an important evolutionary link between single-celled algae and flowering plants.

Complex path to cell death shown by identification of new genes

Can a tiny winged insect's salivary glands really tell us about processes relevant to human disease? Yes, according to a new study by researchers at the University of Massachusetts Medical School (UMMS), who gained new insights into autophagy - a cellular degradation process associated with a form of programmed cell death - by studying the salivary gland cells of the fruit fly.

How molecular muscles help cells divide

Time-lapse videos and computer simulations provide the first concrete molecular explanation of how a cell flexes tiny muscle-like structures to pinch itself into two daughter cells at the end of each cell division, according to a report in Science Express.
