Researchers Create Noninvasive Technology That Detects When Nerve Cells Fire

Researchers at Stanford University, Palo Alto, California, have created a noninvasive technology that detects when nerve cells are based on changes in shape. The method could be used to observe nerve activity in light-accessible parts of the body, such as the eye, which would allow physicians to quantitatively monitor visual function at the cellular level.The work was funded by the National Eye Institute, part of the National Institutes of Health.

Blood Test Helps Identify Distinct Molecular Signatures In Children With Cystic Fibrosis

Researchers at Stanley Manne Children's Research Institute at Ann & Robert H. Lurie Children's Hospital of Chicago, and colleagues, used a blood test and microarray technology to identify distinct molecular signatures in children with cystic fibrosis. These patterns of gene expression could help predict disease severity and treatment response, and lead to therapies tailored to each patient's precise biology. Findings were published in  Physiological Genomics.

The Importins Of Anxiety

According to some estimates, up to one in three people around the world may experience severe anxiety in their lifetime. In a study described today in  Cell Reports , researchers at the Weizmann Institute of Science have revealed a previously unknown mechanism underlying anxiety. Targeting this biochemical pathway may help develop new therapies for alleviating the symptoms of anxiety disorders.

New Cells For Norovirus Production In The Lab

An Osaka University-led research team has developed a system for simply and inhuman producing norovirus. By coaxing human induced pluripotent stem cells (iPSCs) to develop into the type of cell that usually leads to the intestine, how can they be used for producing the virus, how can it interact with human cells, and investigating potential vaccines?
