NHCS researchers develop human heart cell model of ARVC

Researchers at the National Heart Centre Singapore (NHCS) have successfully created a human heart cell model of arrhythmogenic right ventricular cardiomyopathy (ARVC), an inherited heart muscle disorder which puts one at high risk of developing life-threatening arrhythmias and sudden cardiac death.

Novel approach to assemble the 'connectome' via genetic barcoding

A team of neuroscientists has proposed a new and potentially revolutionary way of obtaining a neuronal connectivity map (the "connectome") of the whole brain of the mouse. The details are set forth in an essay published October 23 in the open-access journal PLOS Biology.

Max Planck scientists aim to analyze the whole mouse brain under electron microscope

What happens in the brain when we see, hear, think and remember? To be able to answer questions like this, neuroscientists need information about how the millions of neurons in the brain are connected to each other.

New way to image how brain cells coordinate with each other to control specific behaviors

A team led by MIT neuroscientists has developed a way to monitor how brain cells coordinate with each other to control specific behaviors, such as initiating movement or detecting an odor.

Salk findings on cold virus proteins may spur new cancer treatments

Cold viruses generally get a bad rap----which they've certainly earned----but new findings by a team of scientists at the Salk Institute for Biological Studies suggest that these viruses might also be a valuable ally in the fight against cancer.

First picture of interaction between leptin and its receptor

Researchers at the University of Michigan have determined how the hormone leptin, an important regulator of metabolism and body weight, interacts with a key receptor in the brain.

New York Stem Cell Foundation names 6 scientists as 2012 NYSCF - Robertson Investigators

The New York Stem Cell Foundation (NYSCF) named six of the most promising scientists as its 2012 NYSCF - Robertson Investigators.

New research lists cell stiffness as possible biomarker for metastatic ovarian cancer

New Georgia Tech research shows that cell stiffness could be a valuable clue for doctors as they search for and treat cancerous cells before they're able to spread. The findings, which are published in the journal PLoS One, found that highly metastatic ovarian cancer cells are several times softer than less metastatic ovarian cancer cells.

Chemotherapy plus immunotherapy can enhance anti-tumor effects in patients with advanced cancer

Researchers at Moffitt Cancer Center and colleagues at the University of South Florida and Tianjin Medical University Cancer Institute and Hospital in China have discovered that combining chemotherapy drugs and immunotherapy cancer vaccines results in an enhanced anti-tumor effect.

Study characterizes movement of rhodopsin

A recent study in The Journal of General Physiology characterizes the movement of rhodopsin, a GPCR and member of a large family of transmembrane receptors responsible for many cellular responses and involved in many human diseases.

Study documents women's experiences after abnormal prenatal chromosomal microarray testing

We often hear that "knowledge is power." But, that isn't always the case, especially when the knowledge pertains to the health of an unborn child, with murky implications, at best. A new study, led by researchers from the Perelman School of Medicine at the University of Pennsylvania, begins to document this exception to the general rule.

Glucocorticoids can thwart androgen receptor activity and regulate fat storage

In the body's ongoing effort to maintain a healthy weight, an arsenal of cellular proteins called androgen receptors is critical for blocking fat accumulation. Now researchers reporting in the September issue of the Cell Press Journal Chemistry & Biology have discovered that naturally occurring steroids called glucocorticoids can thwart the receptors' activity, ultimately encouraging fat buildup.

Caltech biologists gain new insight into migrating cells

At any given moment, millions of cells are on the move in the human body, typically on their way to aid in immune response, make repairs, or provide some other benefit to the structures around them. When the migration process goes wrong, however, the results can include tumor formation and metastatic cancer. Little has been known about how cell migration actually works, but now, with the help of some tiny worms, researchers at the California Institute of Technology (Caltech) have gained new insight into this highly complex task.

Biologists elucidate how muscle stem cells colonize special niches

Muscles have a pool of stem cells which provides a source for muscle growth and for regeneration of injured muscles. The stem cells must reside in special niches of the muscle for efficient growth and repair.

Researchers obtain first detailed and complete picture of PRC2 protein

The first detailed and complete picture of a protein complex that is tied to human birth defects as well as the progression of many forms of cancer has been obtained by an international team of researchers led by scientists with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab).

Brandeis University biology professor receives NIH Director's New Innovator award

Chances are you didn't spend much time this morning getting your shoes on or thinking about which route you would take to work. But for people suffering with debilitating diseases such as ALS (Lou Gehrig's disease) or Alzheimer's, such simple functions -- and even activities like breathing and eating -- can be a struggle.

Novel method could help advance fight against persistent 'HIV latency'

Scientists at the Gladstone Institutes have gotten us one step closer to understanding and overcoming one of the least-understood mechanisms of HIV infection-by devising a method to precisely track the life cycle of individual cells infected with HIV, the virus that causes AIDS.

Stanford and MBL scientists win prestigious Lasker Awards

Scientists who invented new ways to study how "cargo" is moved within cells and, as a result, discovered a new biological motor protein, kinesin, at the Marine Biological Laboratory (MBL) in Woods Hole, Mass., have received the prestigious 2012 Lasker Award for Basic Medical Research, the Albert and Mary Lasker Foundation announced today.

Biopsies may misdiagnose eosinophilic esophagitis

University of Utah engineers mapped white blood cells called eonsinophils and showed an existing diagnostic method may overlook an elusive digestive disorder that causes swelling in the esophagus and painful swallowing.
