Though picking up a Salmonella infection abroad could ruin your holiday, reporting it to your doctor could help detect emerging infections in tourist destinations, according to an article published today in BMC Medicine. A comprehensive database containing details of the infections that travellers pick up could help inform countries that have limited surveillance systems about possible disease outbreaks.
In Sweden, all reported cases of Salmonella infection must be entered into the Swedish Infectious Disease Register, detailing the type of bacteria that caused the infection and the place where the infection was contracted. Karin Nygård and her colleague used this database to assess whether there had been any changes in the numbers or types of Salmonella infection from different geographical regions between 1997 and 2002.
Their analyses of 13,271 cases of Salmonella infection in Swedes showed that 87% of these infections were contracted abroad. Most infections were reported from Spain, Greece and Turkey, mainly reflecting the popularity of these travel destinations for Swedish charter tourism.

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
