A pair of rare enzymes in marine microorganisms could boost carbon storage
Characteristics of cyanobacteria with multiple Rubisco types. (A) Ribosomal protein tree showing the ODZ Prochlorococcus lineage and its Rubisco. (B) Form II Rubisco gene tree showing representative AMZ IB sequences and their phylogenetic background. The tips of the trees are labeled with sequence numbers (Dataset S2). (C) Maximum carboxylation rate (kcat) of type II rubiscos reported in ref. AMZ IB…

Manganese cathodes could boost lithium-ion battery performance
A new process for manganese-based battery materials allows researchers to use larger particles, pictured here with a scanning electron microscope. Credit: Han-Min Hau/Berkeley Lab and University of California, Berkeley Rechargeable lithium-ion batteries are increasingly being used in devices such as smartphones, laptops, electric vehicles and energy storage systems, but supplies of nickel and cobalt, which are often used in the…
