Two DNA defense systems behind resilience of 7th cholera pandemic
Two DNA defense systems behind resilience of 7th cholera pandemic
Two DNA defense systems protect the bacterial strains responsible for the ongoing seventh cholera pandemic from potentially harmful genetic material and viruses, scientists have found. Their study also shows that the defense systems may have been key in the evolution and success of these strains. Cholera is caused by the bacterium Vibrio cholerae , a waterborne pathogen that infects the gut of humans through contaminated water and food.

Role of fish in mixing and spreading nutrients in coastal waters revealed
Role of fish in mixing and spreading nutrients in coastal waters revealed
Oceans are made up of multiple layers, ranging from lighter, warmer waters at the top to denser, cooler waters at the bottom. Ocean mixing is vital to move heat, oxygen, nutrients and pollutants between different layers and therefore plays a major role in how ecosystems can sustain life. Although it is well established that winds and tides supply the bulk of the energy that drives mixing, the contribution made by swimming organisms has not been understood until now.

A Single Gene Controls Species Diversity in an Ecosystem
To test if a single gene could affect an entire ecosystem, a research team of the University of Zurich conducted a lab experiment with a plant and its associated ecosystem of insects. They found that plants with a mutation at a specific gene foster ecosystems with more insect species. The discovery of such a -keystone gene- could change current biodiversity conservation strategies.

In the heat of the wound
A bandage that releases medication as soon as an infection starts in a wound could treat injuries more efficiently. researchers are currently working on polymer fibers that soften as soon as the environment heats up due to an infection, thereby releasing antimicrobial drugs. It is not possible to l from the outside whether a wound will heal without problems under the dressing or whether bacteria will penetrate the injured tissue and ignite an inflammation.
