研究人员运用了基因工程技术，将来自大肠杆菌的 MerA 和 MerB 基因，通过精心设计和操作，分别导入果蝇（Drosophila melanogaster）和斑马鱼（Danio rerio）体内。在果蝇实验中，研究人员对基因进行了密码子优化，使其更适合在果蝇中表达，并利用 PhiC31 介导的整合技术，将表达载体精准地整合到果蝇基因 ...

他们从汞污染矿区分离出具有抗性的细菌，将其有机汞裂解酶（MerB）和汞还原酶（MerA）基因导入 Bt 中，赋予 Bt 对 MeHg 的解毒能力。 研究表明，Bt merA/B 在体外以及口服 MeHg 或富含 MeHg 鱼类饲料的小鼠肠道内，均能使 MeHg 发生去甲基化反应。

MerB’ys Newfoundlanders of varying bodies, identities, ethnicities, and experiences with masculinity come together to create something silly and meaningful in the 2020 MerB’ys Calendar.

The merA/merB-3 and merA/merB-5 lines had intermediate Hg (0) evolution rates and grew on 5 μM PMA though much more slowly than the aforementioned lines. The remaining lines, merA/merB-4 and merA ...

Merb will be folded into Rails 3, the next major version of the open source web framework. This unexpected union will put an end to the rivalry between the two projects.

Merb is nearing a 1.0 release milestone and the team has some great changes in store for those people either using Merb today or planning on picking it up for a new project. Read what's coming soon.

Web framework Merb 1.0 RC1 is now available. We talked to Merb maintainer Yehuda Katz to get an update on new features and the future of Merb.
