Scientists invent way to reversibly silence brain cells using pulses of yellow light

Scientists at the MIT Media Lab have invented a way to reversibly silence brain cells using pulses of yellow light, offering the prospect of controlling the haywire neuron activity that occurs in diseases such as epilepsy and Parkinson's disease.

Possible therapeutic target for Duchenne muscular dystrophy

In the April 1st issue of Genes & Development, Dr. Bruce Spiegelman (Dana Farber Cancer Institute) and colleagues identify a key genetic component of and possible therapeutic target for Duchenne muscular dystrophy.

Researchers use poliovirus to destroy neuroblastoma tumors in mice

The cause of one notorious childhood disease, poliovirus, could be used to treat the ongoing threat of another childhood disease, neuroblastoma.

Interferon gamma identified as one of the signaling proteins involved with tumor relapse

Researchers at Virginia Commonwealth University's Massey Cancer Center studying the interaction between the immune system and cancer cells have identified interferon gamma as one of the signaling proteins involved with tumor relapse.

Researchers show how endocrine cell types are produced in the pancreas

An international research team has identified the process by which pancreatic progenitor cells give rise to different endocrine cell types.

microRNAs undergo molecular editing with significant physiological consequences

Tiny molecules called microRNAs, only 19 to 21 nucleotides in length, are able to effectively silence sometimes large sets of genes. They do this by specifically binding to and neutralizing another form of RNA called messenger RNA, responsible for conveying the information from genes to the cellular machinery that uses that information to create proteins, the building blocks of the body.

Why is heart shaped like it is?

How does the heart attain its characteristic shape? Shape may be sculpted by cell movement, cell division, or changes in cell size and shape, all of which can be influenced by the local environment. The heart appears as a simple tube early in development; later, the tube walls bulge outward to form the cardiac chambers.

Peptide vaccine fights off breast tumors with help of bacteria-mimicking agents

With the help of immune system-stimulating molecules that mimic bacterial components, researchers have used a type of cancer vaccine to both delay and prevent breast tumors in mice.

An active mind delays the onset of Alzheimer's

Learning appears to slow the development of two brain lesions that are the hallmarks of Alzheimer's disease, scientists at UC Irvine have discovered. The finding suggests that the elderly, by keeping their minds active, can help delay the onset of this degenerative disease.

Retinoblastoma gene may play a critical role in the development of the placenta

An important cancer-related gene may play a critical role in the development of the placenta, the organ that controls nutrient and oxygen exchange between a mother and her fetus during pregnancy, and perhaps in miscarriages.

Abnormal hair development and apparent follicular transformation to mammary gland in the absence of Hedgehog signaling

One single molecule determines how stem cells in the hair follicle develop. A study at the Sahlgrenska Academy at Göteborg University in Sweden has shown that cells that should give rise to hair can instead give rise to mammary gland cells in mice who lack this molecule.

Stem cell therapy promises hope for muscular dystrophy victims

Italian scientists, by using new stem cell therapy on dogs with muscular dystrophy, have improved the dogs condition to such an extent that the dogs were able to walk and even jump again.

Potential for first diagnostic DNA test to guide antidepressant treatment

Treatment of depression is difficult for both patients and for psychiatrists. While there are numerous drugs available that work, finding the right one -- or right combination -- is, at times, a matter of trial and error.

Cabernet Sauvignon may reduce incidence of Alzheimer's Disease

A new study directed by Mount Sinai School of Medicine has found that moderate red wine consumption in a form of Cabernet Sauvignon may help reduce the incidence of Alzheimer's Disease (AD).

Green tea slows down plaque formation in Huntington's disease

Green tea can apparently inhibit the formation of the lethal protein aggregates that are a characteristic feature of Huntington's disease (HD).

New class of super NSAIDs

Building on previous work, researchers at the University of Pennsylvania School of Medicine have found that deleting an inflammation enzyme in a mouse model of heart disease slowed the development of atherosclerosis.

Transgenic goat's milk could help tackle children's intestinal disease

Milk produced by transgenic goats, which carry the gene for an antibacterial enzyme found in human breast milk, altered the intestinal bacteria in young goats and pigs that were fed the milk.

Research findings may speed the development of vaccines for Chlamydia and other STDs

Using a novel mouse model that allows scientists to study how the immune system’s fighter cells respond to invaders in the genital tract during the initial stage of infection, researchers have found a way to track immunity against Chlamydia trachomatis.

Major genetic breakthrough in understanding of Wolbachia infection

Scientists have made a major breakthrough in understanding the genetics of the insect parasite that is being targeted by researchers as a way of preventing the spread of malaria.
