Insertion of the FeB cofactor in cNORs lacking metal inserting chaperones
Nitric oxide reductase is an enzyme found in the bacterial denitrification pathway. The NOR active site contains a non‐heme iron, often, but not always inserted with the assistance of chaperones. Here, we study the insertion of FeB in the subfamily of cNORs lacking chaperones and found a putative channel, conserved in the family, perhaps enabling the ...

Viruses in sanctuary chimpanzees across Africa
Abstract Infectious disease is a major concern for both wild and captive primate populations. Primate sanctuaries in Africa provide critical protection to thousands of wild‐born, orphan primates confiscated from the bushmeat and pet trades. However, uncertainty about the infectious agents these individuals potentially harbor has important implications ...

Considering the Risks and Costs of Solid Organ Xenotransplantation
This perspective discusses the rationale, risks, and costs of whole‐organ xenotransplantation. It considers alternative strategies to obviate the demand for transplants and optimize allotransplantation systems and practices that do not impose xenotransplantation's harms and risks, and whether they are the most ethical and effective means to increase ...

The seed pod valves of Australian Banksia attenuata plants are not simply bi‐layers which bend when dry. These experiments and models reveal complex mechanics, which allow seed release only after several steps of seed pod opening. Stiffness gradients prevent delamination of the valves during loading, and a shape‐memory function protects the seeds ...

A rare case of giant panda cancer: Pancreatic ductal adenocarcinoma
Pancreatic tissues' tumors exhibited three different situations. (A) Several glandular tubular adenocarcinoma structures could be seen in pancreatic tissue. (B) Tubular area could be seen in the pancreas, exhibiting papillary growth in the area.

Super‐Tough Silk: The Potential of Knots in Evolved Spiders
The toughness of spider silk can be further significantly enhanced if spiders evolved the –currently absent/undiscovered– ability to tie knots in their silk. The results on 393 spiders suggest toughness increments by one or two orders of magnitude and thus a new perspective on how knotting can serve as a key innovation in spider evolution and in ...

A Strong and Water‐Retaining Biomass Adhesive Inspired by Tofu
Drawing inspiration from the formation mechanism of the traditional food tofu, a strong and water‐retaining adhesive is designed using the soybean meal (SM) oxidized by glucose oxidase (GOx) and calcium sulfate oligomer (CSO). This design strategy effectively addresses the conflicting requirements of water‐resistant bonding strength and water retention

Synthetic cells are engineered herein to respond to an external chemical messenger by the activation of intracellular catalysis. The chemical messenger molecules are catalytically generated by an extracellular enzyme or a mineral surface, whereas the intracellular catalysis emerges via direct enzyme activation or via protein refolding.
