Egg secretions from a worm may be useful in gene therapy

Egg secretions from a worm that causes a deadly human disease may prove useful in gene therapy, according to research presented at the British Pharmaceutical Conference (BPC) in Manchester.

Gold nanorods for medical applications

Gold nanoparticles are under consideration for a number of biomedical applications, such as tumor treatment. A German-American research team at Carnegie Mellon University in Pittsburgh, Hunter College in New York, and the RWTH Aachen has now developed a new method for the production of nanoscopic gold rods. In contrast to previous methods, they have achieved this without the use of cytotoxic additives.

Atomic structure of the mammalian "fatty acid factory" determined

Mammalian fatty acid synthase is one of the most complex molecular synthetic machines in human cells. It is also a promising target for the development of anti-cancer and anti-obesity drugs and the treatment of metabolic disorders. Now researchers at ETH Zurich have determined the atomic structure of a mammalian fatty acid synthase. Their results have just been published in Science magazine.

Living sensor can warn of arsenic pollution

Scientists studying arsenic pollution have discovered a living sensor that can spot contamination. They have also discovered new bacteria that can clean up arsenic spills even in previously untreatable cold areas, microbiologists heard today (Monday 8 September 2008) at the Society for General Microbiology's Autumn meeting being held this week at Trinity College, Dublin.

Milk may help bacteria survive against low levels of antibiotics

Milk may help prevent potentially dangerous bacteria like Staphylococcus from being killed by antibiotics used to treat animals, scientists heard today (Monday 8 September 2008) at the Society for General Microbiology's Autumn meeting being held this week at Trinity College, Dublin.

Rattlesnake-type poisons used by superbug bacteria to beat our defences

Colonies of hospital superbugs can make poisons similar to those found in rattlesnake venom to attack our bodies' natural defences, scientists heard today (Monday 8 September 2008) at the Society for General Microbiology's Autumn meeting being held this week at Trinity College, Dublin.

Framing the concept of a gene

Even scientists define 'a gene' in different ways, so it comes as little surprise that the media also have various ways of framing the concept of a gene, according to a new study appearing in the October 2008 issue of EMBO reports.

Nature inspires new highly specific drugs and organic products

The best place to seek novel compounds for pharmaceutical drugs, alternative energy sources, and a host of industrial applications, is within natural systems that have evolved over millions of years.

New stem cell tools to aid drug development

Scientists have designed, developed and tested new molecular tools for stem cell research to direct the formation of certain tissue types for use in drug development programmes.

Some stem cells take charge of their surroundings

Adult stem cells are not pampered pushovers. O'Reilly et al. report that certain stem cells take charge of their surroundings, molding their environment to control their division and differentiation.

Mosquitoes stay away from DEET because they hate the smell!

According to scientists in the U.S. the reason why the insect repellent DEET works so well is because mosquitoes don't like the smell.

Scientists trace evolution of the nerve cell

University of Queensland researchers have traced the origins of one of the most important steps in animal evolution - the development of nerves.

Scientists synthesize promising anti-cancer product from marine algae

Duke University chemists have patented an efficient technique for synthesizing a marine algae extract in sufficient quantities to now test its ability to inhibit the growth of cancerous cells while leaving normal cells unaffected.

Evolution in the ribosome

A new study of the ribosome, the cell's protein-building machinery, sheds light on the oldest branches of the evolutionary tree of life and suggests that differences in ribosomal structure between the three main branches of that tree are "molecular fossils" of the early evolution of protein synthesis.

Fish melanoma gene linked to pigment pattern that attracts mates

Though skin cancer is deadly to male fish, it also has one perk: The black melanoma splotches arise from attractive natural markings that lure female mates. A new study published in the Proceedings of the National Academy of Sciences this week shows that the melanoma gene can be conserved in swordtail fish because of its beneficial role in sexual selection.

Researchers uncover attack mechanism of illness-inducing bacterium found in shellfish

An infectious ocean-dwelling bacterium found in oysters and other shellfish kills its host's cells by causing them to burst, providing the invader with a nutrient-rich meal, researchers at UT Southwestern Medical Center have found.

Spice-based compound to fight against cancer

Seeking to improve on nature, scientists used a spice-based compound as a starting point and developed synthetic molecules that, in lab settings, are able to kill cancer cells and stop the cells from spreading.

Dual-mode nanoparticles image tumors using MRI and PET

Medical imaging represents one of the most used and useful procedures in the oncologist's diagnostic toolkit, even though each of the most useful techniques-magnetic resonance imaging (MRI), computerized tomography x-ray imaging (CT), and positron emission tomography (PET) scanning-has its own set of limitations.

Scientists discover reservoir of mitochondrial DNA mutations present in the general population

Researchers at the University of Newcastle, England, and the Virginia Bioinformatics Institute at Virginia Tech in the United States have revealed a large reservoir of mitochondrial DNA mutations present in the general population. Clinical analysis of blood samples from almost 3,000 infants born in north Cumbria, England, showed that at least 1 in 200 individuals in the general public harbor mitochondrial DNA mutations that may lead to disease.

Researchers find a cancer-inhibiting cyanobacteria that grows on coral reefs

University of Florida College of Pharmacy researchers have discovered a marine compound off the coast of Key Largo that inhibits cancer cell growth in laboratory tests, a finding they hope will fuel the development of new drugs to better battle the disease.
