Stem Cell Fate Depends on 'Grip'
March 28, 2013 Scientists have generated new insight on how a stem cell's environment influences what type of cell a stem cell will become. They have shown that whether human mesenchymal stem cells turn into fat or ... > full story -
Biological Transistor Enables Computing Within Living Cells
March 28, 2013 Bioengineers have taken computing beyond mechanics and electronics into the living realm of biology. Scientists have used a biological transistor made from genetic material -- DNA and RNA -- in place ... > full story -
Protective Prion Keeps Yeast Cells from Going It Alone
March 28, 2013 A team of scientists has added markedly to the job description of prions as agents of change, identifying a prion capable of triggering a transition in yeast from its conventional single-celled form ... > full story -
Mixed Signals: Combinations of Estrogen-Mimicking Chemicals Strongly Distort Hormone Action
March 28, 2013 What happens when -- as in the real world -- an individual is exposed to multiple estrogen-mimicking chemicals at the same time? Researchers have used new techniques to study exposure to low doses of ... > full story -
Parkinson's Disease Protein Gums Up Garbage Disposal System in Cells
March 28, 2013 With a new neuron model system of Parkinson's disease pathologies, researchers have demonstrated that these aberrant clumps in cells resist degradation as well as impair the function of the ... > full story -
Brain's 'Molecular Memory Switch' Identified
March 28, 2013 Scientists have identified a key molecule responsible for triggering the chemical processes in our brain linked to our formation of memories. The findings reveal a new target for therapeutic ... > full story -
You Are What You Eat -- Even the Littlest Bites: Dietary Influences Tied to Changes in Gene Expression
March 28, 2013 Sometimes you just can't resist a tiny piece of chocolate cake. Even the most health-conscious eaters find themselves indulging in junk foods from time to time. New research raises the striking ... > full story -
Opposites Attract: How Cells and Cell Fragments Move in Electric Fields
March 28, 2013 Like tiny crawling compass needles, whole living cells and cell fragments orient and move in response to electric fields -- but in opposite directions, scientists have found. Their results could ... > full story -
How Herpesvirus Invades Nervous System
March 28, 2013 Scientists have identified a component of the herpesvirus that "hijacks" machinery inside human cells, allowing the virus to rapidly and successfully invade the nervous system upon initial ... > full story -
Childhood Asthma Tied to Combination of Genes and Wheezing Illness
March 27, 2013 About 90 percent of children with two copies of a common genetic variation and who wheezed when they caught a cold early in life developed asthma by age 6, according to a new study. They were nearly ... > full story
