It’s also worth noting that even if alternatives superior to agar were found, scientists are reluctant to abandon established protocols (even when microbiologists do use other jellies, they often still add agar to the mix, for example, to increase the gel strength of the solid media). As agar has been the standard gelling agent in microbiology for around 150 years, an enormous infrastructure of standardized methods, reference values, and quality control procedures has emerged around its specific properties. Switching to a different medium (even a superior one) means results may not be directly comparable to decades of published literature or to other laboratories’ findings.
Developers using the streams API are expected to remember to use options like highWaterMark when creating their sources, transforms, and writable destinations but often they either forget or simply choose to ignore it.

Current X-ray lasers require facilities that are kilometres long. A cavity-based set-up about 66 metres in length has been developed that uses highly reflective mirrors to enable the generation of high-intensity pulses of narrow-band X-ray radiation. This promises to overcome the limitations of current X-ray lasers.
