Imaging electric charge propagating along microbial nanowires

Posted: 19 Oct 2014 12:18 PM PDT

Physicists report that they've used a new imaging technique, electrostatic force microscopy, to resolve the biological debate with evidence from physics, showing that electric charges do indeed propagate along microbial nanowires just as they do in carbon nanotubes, a highly conductive human-made material.

Lab-developed intestinal organoids form mature human tissue in mice

Posted: 19 Oct 2014 12:18 PM PDT

Researchers have successfully transplanted 'organoids' of functioning human intestinal tissue grown from pluripotent stem cells in a lab dish into mice -- creating an unprecedented model for studying diseases of the intestine. Scientists said that, through additional translational research, the findings could eventually lead to bioengineering personalized human intestinal tissue to treat gastrointestinal diseases.

A major breakthrough could lead to more effective methods for detoxifying dangerous pollutants like PCBs and dioxins, scientists say. The result is a culmination of 15 years of research. It details how certain organisms manage to lower the toxicity of pollutants. 

Smoking during pregnancy alters newborn stress hormones, DNA, study finds

Posted: 17 Oct 2014 03:37 PM PDT

The effects of smoking during pregnancy, and its impact on the stress response in newborn babies, has been the focus of recent study. The research indicates that newborns of mothers who smoke cigarettes during pregnancy show lower levels of stress hormones, lowered stress response, and alterations in DNA for a gene that regulates passage of stress hormones from mother to fetus.
