Life

Chemistry, the intricate dance of atoms and molecules, fuels life's essence. It molds DNA, drives metabolism, enables reactions, and unlocks the secrets of medicines, materials, and the natural world.

Enhancing plant protein functionality by using physical modification techniques

Plant proteins have attracted attention recently as a possible food source for the growing world population. However with limited applications in their current form, modification would be necessary. This article discusses their importance, the reasons for modification, and their potential applications.

The double helix revisited

This paper uses metadata about the three papers that collectively announced the discovery of the structure of DNA in 1953, specifically looking at references and citations. These data together with sentiment analysis of the books written by two of the scientists involved – James Watson and Maurice Wilkins – suggest that while an authoritative version of the history of the science might be possible, an authoritative history that includes the social dynamics of the research environment is unlikely. The closing section of the paper alludes to the advances in Māori and Polynesian ethnography made possible by post-discovery DNA-related research.
