Salad & Salmonella: Food Poisoning as a Side Dish

Salmonella can also infect plant cells and successfully evade all the defence mechanisms of plants. As a result, cleaning the surfaces of raw fruits and vegetables, e.g. by washing, is not sufficient to protect against food poisoning. This surprising discovery, made during a project supported by the Austrian Science Fund FWF, has been published today. The results of the project are based on a model plant, which also represents the ideal basis for future development work on treatment and testing systems in the area of food safety.

Superconductor in inertial fusion targets

Inertial fusion tries to make the fusion of deuterium and tritium by implosion of a target irradiated with lasers. This implosion is obtained in an indirect way by the expansion under the impact of lasers of an ablative material that surrounds the mixture D-T. Three important parameters control inertial fusion.
