The Place of RNA in the Origin and Early Evolution of the Genetic Machinery
The extant genetic machinery revolves around three interrelated polymers: RNA, DNA and proteins. Two evolutionary views approach this vital connection from opposite perspectives.

In this work, we have employed the first-principles quantum physics method to investigate the light-metal based LiAl(NH2)4 and its modified compounds as conversion electrode materials for sodium-ion batteries on the basis of state-of-the-art Density ...

Thermal and Magmatic Evolution of the Moon
As with all science, our continually developing concepts of lunar evolution are firmly tied to both new types of observations and the integration of these observations to the known pool of data. This process invigorates the intellectual foundation on which old models are tested and new concepts are built.

Thermal analysis of microstructural evolution of Al2O3 surface modified layers [PDF]
Solidification behavior and microstructural evolution of surface modified layers in plasma cladding technique are studied via numerical simulations. Both the coupling effect of temperature and solid volume fraction are considered in the proposed thermal ...

The evolution of thermal physiology in endotherms
Biologists usually refer to mammals and birds as homeotherms, but these animals universally experience regional and temporal variations in body temperature. These variations could represent adaptive strategies of heterothermy, which in turn would favor genotypes that function over a wide range of temperatures.
