Scientists investigate molecular mechanism of memory encoding in neurons

University of Alberta led research may have discovered how memories are encoded in our brains. Scientists understand memory to exist as strengthened synaptic connections among neurons. However components of synaptic membranes are relatively short-lived and frequently re-cycled while memories can last a lifetime.

Study determines why blood oranges develop anthocyanin pigments

The anthocyanin pigments that provide the "blood" color of blood oranges are not produced in significant amounts unless the fruit is exposed to cold conditions during its development or post-harvest. No cold exposure means poor anthocyanin production and the loss of the entire crop. This means that blood oranges can be grown in many areas of the world, but they are most likely to be exposed to the correct temperature conditions in only a few regions, including their major area of production in Sicily.

FDA, Agilent partner to develop new tools for detection of salmonella subtypes

Agilent Technologies Inc. today announced that it has entered into a Cooperative Research and Development Agreement with the U.S. Food and Drug Administration to develop new tools to detect and analyze pathogens in food.

Mayo Clinic researchers train mouse immune systems to eradicate skin cancer from within

Mayo Clinic researchers have trained mouse immune systems to eradicate skin cancer from within, using a genetic combination of human DNA from melanoma cells and a cousin of the rabies virus. The strategy, called cancer immunotherapy, uses a genetically engineered version of the vesicular stomatitis virus to deliver a broad spectrum of genes derived from melanoma cancer cells directly into tumors.

New antibiotic shows promise against bovine mastitis

Food-borne diseases might soon have another warrior to contend with, thanks to a new molecule discovered by chemists at the University of Illinois. The new antibiotic, an analog of the widely used food preservative nisin, also has potential to be a boon to the dairy industry as a treatment for bovine mastitis.

FHCRC research represents potential breakthrough in treatment of pancreas cancer

Pancreas cancer tumors spread quickly and are notoriously resistant to treatment, making them among the deadliest of malignancies. Their resistance to chemotherapy stems in part from a unique biological barrier the tumor builds around itself. Now scientists at Fred Hutchinson Cancer Research Center have found a way to break through that defense, and their research represents a potential breakthrough in the treatment of pancreas cancer.

Hedgehog and mTOR pathway are active in esophageal cancer

Identification of a non-traditional pathway for spiriting a cancer-promoting protein into the cell nucleus points to a possible combination therapy for esophageal cancer and indicates a mechanism of resistance for new drugs that attack the Hedgehog pathway.

Circadian rhythms control production of metabolites

By analyzing the hundreds of metabolic products present in the liver, researchers with the UC Irvine Center for Epigenetics & Metabolism have discovered that circadian rhythms - our own body clock - greatly control the production of such key building blocks as amino acids, carbohydrates and lipids.

Study identifies new hypervariable regions in human gut viruses

A growing body of evidence underscores the importance of human gut bacteria in modulating human health, metabolism, and disease. Yet bacteria are only part of the story. Viruses that infect those bacteria also shape who we are. Frederic D. Bushman, PhD, professor of Microbiology at the Perelman School of Medicine at the University of Pennsylvania, led a study published this month in the Proceedings of the National Academy of Sciences that sequenced the DNA of viruses -- the virome -- present in the gut of healthy people.

iPSYCH project to study five specific mental disorders

Is it possible to prevent the development of schizophrenia? Can certain patients develop autism if they carry a specific gene and have been exposed to a viral fetal infection? Should all ADHD patients take the same type of medication? This unique research project will try to answer these questions. The project is based at Aarhus University and will be known as 'The Lundbeck Foundation's Initiative for Integrative Psychiatric Research.'

Single dose of X-ray radiation can prevent glaucoma

Jackson Laboratory researchers have demonstrated that a single, targeted x-ray treatment of an individual eye in young, glaucoma-prone mice provided that eye with apparently life-long and typically complete protection from glaucoma.

New solid state NMR method can help visualize structure of proteins

A new method to reveal the structure of proteins could help researchers understand biological molecules - both those involved in causing disease and those performing critical functions in healthy cells.

Researchers discover new method to identify cancer-causing translocations

Researchers from Huntsman Cancer Institute (HCI) at the University of Utah report they have discovered a method to identify cancer-causing rearrangements of genetic material called chromosomal translocations quickly, accurately, and inexpensively.

Disruptions in immune system regulation may play a role in NEC

Despite advances in neonatal care, necrotizing enterocolitis (NEC) - the most common gastrointestinal emergency in premature infants - continues to be a deadly disease. "We haven't made a lot of progress in identifying babies early who may be at risk for NEC, preventing it or treating it," said J-rn-Hendrik Weitkamp, M.D., a neonatologist and assistant professor of Pediatrics at Monroe Carell Jr. Children's Hospital at Vanderbilt.
