|Stress Triggers Key Molecule to Halt Transcription of Cell's Genetic Code|
Biology » Transcription, Dna »
Stowers Institute for Medical Research − Kansas City, MO. -- If DNA is the cookbook of life, then RNA is the scratch paper where the cell writes down its favorite recipes. These recipes could make the pigments of your skin, the vehicles that carry oxygen through your veins, or the signaling molecules that keep cancer in check. Sometimes, when the cell's transcription machinery copies these recipes, it stutters or stalls, either because it gets off task or it comes across a problem with the cookbook. Then, the cell has

Columbia Engineering Professor Venkat Venkatasubramanian has led a study that examines income inequality through a new approach: he proposes that the fairest inequality of income is
|A Better Understanding of Links Between Pain And Anxiety Reveals Treatment Opportunities|
Biology » Pain, Chronic »
Canadian Association for Neuroscience − Pain has both physical and emotional components. Anxiety is common in people suffering from chronic pain, and people with anxiety are more likely to suffer from chronic pain. Dr. Min Zhuo and his team at the University of Toronto have found the biological basis for this link in the connections between neurons in a brain region known as the anterior cingulate cortex (ACC). Better yet, they have identified a molecule that can reduce chronic pain-related anxiety. Dr. Zhuo's latest results were presented at
