Shingles

Shingles. Artwork of varicella-zoster virus particles (virions, blue) during shingles. Each viron comprises an icosahedral (20-sided) capsid containing viral DNA, surrounded by surface protein spikes. When this virus is reactivated from an earlier chicken pox infection, it causes shingles or herpes zoster. The virus travels along sensory nerves to the skin where it causes small blisters (red), usually on the trunk or face. The blisters last around two weeks and, if untreated, nerve damage causes severe pain in the affected area. Reactivation may be associated with stress or reduced immune function. Antiviral drugs, like acyclovir, can help if taken early on

Scientists holding GM tomatoes

MODEL RELEASED. Genetically engineered tomato. Conceptual image of two scientists holding genetically modified tomatoes. Genetic engineering of plants involves altering their DNA (deoxyribonucleic acid) by adding genes from another organism. Traits such as resistance to diseases and pesticides can be introduced to the plant, which may save time and money during cultivation and harvesting. Tomatoes have so far been genetically engineered to be resistant to fungus, thereby prolonging their freshness during transportation. Many people actively campaign against genetic modification of food crops, fearing that it will harm the environment
