Dr. Marta is the Principal Researcher at the Institut de Biologia Molecular de Barcelona where her team studies formation of tissues and organs during development. Her recent publication in PLoS Genetics sheds more light on chitin deposition.  Here's Dr. Marta speaking more about her publication, women in science and working as a scientist.  CTS: How has your recent publication added to existing knowledge about the chitin deposition?  Chemical structure of chitin (Photo credit: Wikipedia ) MLC: Chitin is a natural polysaccharide made of UDP-N-acetylglucosamine monomers (a derivative of glucose). It is the second most abundant polymer in nature after cellulose, and from a

When into the ant ’s system, it alters the behaviour of the ant to ensure it spreads its spores in the environment. Ants that are infected, referred to as zombie ants, wonder alone and perch themselves on branches, or leaves ensuring the viability of the fungus. Experts have witnessed that the ants generally chose a spot that is high in humidity, and have temperatures between 20-30 degrees making sure that the fungus survives
