Structural insights into inhibition of lipid I production in bacterial cell wall synthesis

Antibiotic-resistant bacterial infection is a serious threat to public health. Peptidoglycan biosynthesis is a well-established target for antibiotic development. MraY (phospho-MurNAc-pentapeptide translocase) catalyses the first and an essential membrane step of peptidoglycan biosynthesis. It is considered a very promising target for the development of new antibiotics, as many naturally occurring nucleoside inhibitors with antibacterial activity target this enzyme. However, antibiotics targeting MraY have not...

Uranium-mediated electrocatalytic dihydrogen production from water

Depleted uranium is a mildly radioactive waste product that is stockpiled worldwide. The chemical reactivity of uranium complexes is well documented, including the stoichiometric activation of small molecules of biological and industrial interest such as H2O, CO2, CO, or N2 (refs 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11), but catalytic transformations with actinides remain underexplored in comparison to transition-metal catalysis....

Graphics cards with 1024GB/s bandwidth? Samsung begins HBM2 production

Samsung has begun mass production of 20nm second-generation High Bandwidth Memory (HBM2), which features up to 256 gigabytes-per-second (GB/sec) of available bandwidth per memory stack—double that of the first generation HBM used in AMD's Fury graphics cards.

HBM2 will also allow for HBM-equipped graphics cards to be packed with more memory—as much as 16GB—surpassing the 4GB limit that AMD...

Influence of extreme weather disasters on global crop production

In recent years, several extreme weather disasters have partially or completely damaged regional crop production. While detailed regional accounts of the effects of extreme weather disasters exist, the global scale effects of droughts, floods and extreme temperature on crop production are yet to be quantified. Here we estimate for the first time, to our knowledge, national cereal production losses across the globe resulting from...
