Nicotinamide adenine dinucleotide (NAD), an indispensable cofactor in cells, participates in diverse redox biochemistry and other nonredox processes. NAD level variation leads to global yet difficult-to-predict biological responses.
A research team led by Prof. ZHAO Zongbao from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences has committed to developing non-natural cofactor-based systems to avoid the limitation associated with NAD level fluctuation.
The team has designed a non-natural coenzyme nicotinamide cytosine dinucleotide (NCD), and engineered a series of oxidoreductases. However, it’s still challenging for microbial cells to take NCD from the environment.

In this work, a combined Voronoi and finite-discrete element method (FDEM) approach for reconstructing the post-fracture model of laminated glass (LG) was proposed. The fracture morphology was determined via introducing Voronoi tessellation with statistical distribution parameters such as the fragment face numbers, volume and sphericity. The residual interaction between glass fragments was described with cohesive zone model. One fractured LG block under uniaxial tension, which was taken from a triple layered LG beam with ionoplast interlayers, was modelled and validated with experimentally recorded data.
Through iteration analysis, the key cohesive parameters were determined for the most applicable model. It is followed by investigating the influence due to the fragments interaction property. The results show that the cohesion and frictional property can be combined to well describe the residual interaction behaviour between fragments. The frictional p

Wuhan Institute of Virology in Wuhan, in China s central Hubei province, during a visit by members of the World Health Organization (WHO) team investigating the origins of the COVID-19 coronavirus. Scientists studying bat diseases at China s maximum-security laboratory in Wuhan were engaged in a massive project to investigate animal viruses alongside leading military officials - despite their denials of any such links.

Stomata, formed by a pair of kidney-shaped guard cells, are tiny pores in leaves. They act like mouths that plants use to eat and breathe. When they open, carbon dioxide (CO
2) enters the plant for photosynthesis and oxygen (O
2) is released into the atmosphere. At the same time as gases pass in and out, a great deal of water also evaporates through the same pores by way of transpiration.
