Article Synopsis
- - Species introductions, particularly of fish in alpine lakes, can change the local food-web structure based on the sizes of the introduced predators, affecting both vertical and horizontal diversity.
- - Increased vertical diversity typically leads to instability in food webs due to longer food chains, while greater horizontal diversity can enhance stability by creating more complex food webs.
- - The study reveals that the interaction between vertical and horizontal diversities is crucial, showing that high vertical diversity destabilizes food webs most significantly when horizontal diversity is low.
The fruit fly is a model organism to study several aspects of metazoan biology. Most of the work has been conducted in adult fruit flies, including laboratory and field-derived specimens, but larvae recently became a valuable model to better understand animal physiology, development, or host-microbe interactions. While adult flies can be easily assigned to a given species based on morphological characteristics, such visual identification is more intricate at the larval stage.

Patients And Methods: A retrospective, single-centre cohort study (2001-11) investigated outcome in adults receiving pristinamycin for MSSA BJI and pristinamycin-related adverse events (AEs).
Results: One hundred and two MSSA BJIs were assessed in 98 patients [chronic infection, 33.
Chemo-mechanotransduction, the way by which mechanical forces are transformed into chemical signals, plays a fundamental role in many biological processes. The first step of mechanotransduction often relies on exposure, under stretching, of cryptic sites buried in adhesion proteins. Likewise, here we report the first example of synthetic surfaces allowing for specific and fully reversible adhesion of proteins or cells promoted by mechanical action.

- PEDOT-PSS and other polyelectrolyte complexes can form films without following the traditional alternating polyanion and polycation layering rule, as demonstrated in this study.
- The research explored the buildup of films using a single solution containing these complexes and found that the film characteristics, such as smoothness, depend on the composition and state of the complexes in the solution.
- A new method, called the 2-in-1 method, was introduced, allowing for controlled film buildup and offering a potential new avenue for surface functionalization with polyelectrolytes.
