Vasopressin in the brain maintains size of vasopressin neurons even when body fluid becomes more diluted

The anti-diuretic hormone "vasopressin" is released from the brain, and known to work in the kidney, suppressing the diuresis.

Population of highly active neurons could provide insight into neocortex

Carnegie Mellon University researchers have found that within the brain's neocortex lies a subnetwork of highly active neurons that behave much like people in social networks.

New stem cell-infused patch improves heart function after myocardial infarction

University of Cincinnati (UC) researchers have found that applying a stem cell-infused patch together with overexpression of a specific cell instruction molecule promoted cell migration to damaged cardiac tissue following heart attack and resulted in improved function in animal models.

Research on adult mammary stem cells may help to cure breast cancer

For the first time, researchers at Fred Hutchinson Cancer Research Center have identified and isolated adult mammary stem cells in mice. Long-term implications of this research may include the use of such cells to regenerate breast tissue, provide a better understanding of the role of adult stem cells in breast cancer development, and develop potential new targets for anti-cancer drugs.

Johns Hopkins Bloomberg School of Public Health awarded Grand Challenges Explorations grant

The Johns Hopkins Bloomberg School of Public Health announced today that it has received a $100,000 Grand Challenges Explorations grant from the Bill & Melinda Gates Foundation. The grant will support an innovative global health research project conducted by Jason Rasgon, PhD, an assistant professor with the Johns Hopkins Malaria Research Institute, and his research to develop an evolution-proof pesticide for eliminating mosquitoes that transmit malaria to humans.

Crystal structures of key fluorescent proteins to "light up" molecules in cells

Scientists at Albert Einstein College of Medicine of Yeshiva University have determined the crystal structures of two key fluorescent proteins - one blue, one red - used to "light up" molecules in cells.

Scientists identify new behavioral traits of immune cells; findings may help in understanding complex diseases

In diseases such as multiple sclerosis, cells of the immune system infiltrate the brain tissue, where they cause immense damage. For many years, it was an enigma as to how these cells can escape from the bloodstream. This is no trivial feat, given that specialized blood vessels act as a barrier between the nervous system and the bloodstream.

Quantitative single cell analysis using optical tweezers and microfluidics

Researchers at the University of Gothenburg, Sweden, have developed a new method to study single cells while exposing them to controlled environmental changes.

Long-term gene therapy used to reverse heart damage in heart failure

Long-term gene therapy resulted in improved cardiac function and reversed deterioration of the heart in rats with heart failure, according to a recent study conducted by researchers at Thomas Jefferson University's Center for Translational Medicine.

Targeted nanoparticles deliver therapeutic DNA to cancer cells

Given that cancer is a disease caused by gene mutations, cancer researchers have been striving to develop gene therapies aimed at correcting these mutations. However, these efforts have been hobbled by the difficulty in safely and efficiently delivering anticancer genes to tumors. Nanoparticles, however, may solve these delivery issues, and two recently published studies, using two different types of nanoparticles, lend credence to that hypothesis.

SRS microscopy helps track molecules and drugs in live cells

A new type of highly sensitive microscopy developed by researchers at Harvard University could greatly expand the limits of modern biomedical imaging, allowing scientists to track the location of minuscule metabolites and drugs in living cells and tissues without the use of any kind of fluorescent labeling.

New imaging technique allows simultaneous tracking of gene expression and movement

Flies expressing green fluorescent protein (GFP) in their retina cells or other tissues can be tracked by specially modified video cameras, creating a real time computer record of movement and gene expression.

How the Nodal gene family keeps the heart in the right (asymmetric) place

Asymmetry is crucial for the heart proper functioning, and now, scientists from the Institute Gulbenkian of Science in Portugal and Harvard University, have discovered that a family of genes, called Nodal, is crucial determining this asymmetry by controlling the speed and direction of the heart muscle cells during embryonic development.

Yerkes researchers develop first transgenic nonhuman primate model of Huntington's disease

In the first study of its kind, researchers at the Yerkes National Primate Research Center, Emory University, in collaboration with researchers from the Department of Human Genetics at Emory's School of Medicine, have developed the first transgenic nonhuman primate model of Huntington's disease (HD), one of the most devastating human neurodegenerative diseases.

Scientists create fluorescent proteins for live cell imaging, biosensor design

Scientists at Carnegie Mellon University's Molecular Biosensor and Imaging Center have developed new "fluorogen activating proteins" (FAPs) that will become a key component of novel molecular biosensor technology being created at Carnegie Mellon.

Tiny fluorescent probes illuminate protein interactions in living cells

While fluorescence has long been used to tag biological molecules, a new technology developed at Yale allows researchers to use tiny fluorescent probes to rapidly detect and identify protein interactions within living cells while avoiding the biological disruption of existing methods, according to a report in Nature Chemical Biology.

How does the opioid system work?

The opioid system controls pain, reward and addictive behaviors. Opioids exert their pharmacological actions through three opioid receptors, mu, delta and kappa whose genes have been cloned (Oprm, Oprd1 and Oprk1, respectively).

Fluorescence resonance energy transfer technology shows how cancer may take hold

A team, led by researchers at the Carnegie Institution,* has found a key biochemical cycle that suppresses the immune response, thereby allowing cancer cells to multiply unabated.
