Results from the Phase 2 trial of the DAR-901 tuberculosis (TB) vaccine were announced today. The three-year trial was conducted among 650 adolescents in Tanzania, a nation with high rates of TB infection, and showed that the vaccine was safe and induced immune responses against the disease.
(Università di Bologna) Their scientific name is “Parazoanthus axinellae” and they are among the most fascinating corals of the Mediterranean Sea. A genetic analysis suggests they may belong to two different species and, therefore, there could be two types of cluster anemone. Researchers claim this may lead to more effective conservation strategies against the negative impact of climate change on this sea population
When a brush fire erupted near Tijuana in early September, a large part of the North American western coast was either on fire or at high risk of fire. The dramatic fire belt stretched from Canada to northern Mexico. Although…

Synthetic dyes are commonly used to assess the toxicity of chemical compounds in cell cultures. However, these dyes damage cells, rendering the cultures useless for long-term experiments. Recently, scientists discovered that a natural food pigment can replace synthetic dyes in cell viability assays for three widely varied types of cells — and performs better. Their approach is also environment-friendly and inexpensive, and opens up possibilities in a range of fields including drug discovery.
