A Feature Paper should be a substantial original Article that involves several techniques or approaches, provides an outlook for future research directions and describes possible research applications. Feature papers are submitted upon individual invitation or recommendation by the scientific editors and must receive positive feedback from the reviewers. Editor’s Choice articles are based on recommendations by the scientific editors of MDPI journals from around the world. Editors select a small number of articles recently published in the journal that they believe will be particularly interesting to readers, or important in the respective research area. The aim is to provide a snapshot of some of the most exciting work published in the various research areas of the journal. Dear Colleagues, Natural products and their analogues have played a very important role in the drug-discovery process. They represent a major source of new che...

Natural Resources & Synthetic Materials NGSS Standard: MS-PS1-3 Gather and make sense of information to describe that synthetic materials come from natural resources and impact society. Key Concepts • Synthetic materials are made from natural resources. • Synthetic materials are made by chemically changing the starting substances to create a material with different characteristics. • Some examples of synthetic materials are plastics, medicines, and new fuels. • A synthetic substance may be chemically identical to a naturally-occurring substance or may be different. • Making and using synthetic materials have both positive and negative impacts on society. Summary The teacher models and describes the kinds of information students will be looking for in their research project on a synthetic product. This is done by using an example of a synthetic product that students make in the classroom: a gel worm (not for eating.) Students make it by combining a sodium alginate solution with a calcium chloride solution. The teacher uses this product to model answers to the three questions students need to answer in their research: • What natural resources are used to make the synthetic product? • What chemical processes are used to make the synthetic product? • What are the negative and positive impacts to society of making and using the synthetic product, compared to making and using a more natural product with a similar function? Students choose or are assigned a synthetic product to r...
