To address the structural biological blind spot with regards to FAs, we pursued the structure of the model bacterial FA curli. Curli fibers are a major component of the extracellular matrix of Gram-negative bacteria and are expressed under biofilm forming conditions where they fulfill a scaffolding...
Bacteria can be engineered to manufacture chemicals, but it is unclear how to optimally engineer a single cell to maximise production performance from batch cultures. Moreover, the performance of engineered production pathways is affected by competition for the host's native resources. Here, using a...

proliferation, cancer cell migration and survival, and tumor cell resistance to apoptotic signals. This, along with the effect of chemokines and growth factors, leads to the formation of a new microenvironment for cancer cells, immune cells, and other stromal constituents that is referred to as th...
Residues may remain in fish used for human consumption and antibiotics released into the environment can lead to the development of antibiotic-resistant bacteria in the food chain. The accumulation of waste feeds in ponds stimulates the growth of bacteria, including human pathogens, which can ...

(Fox et al.2022). Key soil-dwelling organisms are known to benefit from fire’s effects, including some mycorrhizal fungi and bacteria (Whitman et al.2019; Fox et al.2022), although effects on many other groups of soil biota remain poorly understood (Pressler et al.2019), in part owing...
Traits, broadly speaking, are measurable attributes or characteristics of organisms. Traits related to function (for example, leaf size, body mass, tooth size or growth form) are often used to understand how organisms interact with their environment and other species via key vital rates such as ...
