This study further supports a connection between acid deposition and forest decline. The authors state, “Continued vigilance in the control of acid rain precursors will be needed to correct these problems, and aggressive options to reduce pollution in rapidly industrializing regions of Latin America, Asia, and Africa are warranted.”
Paper-Based Blood Typing Device That Reports Patient’s Blood Type “in Writing” Li, M.; Tian, J.; Al-Tamimi, M.; Shen, W. Angew. Chem. Int. Ed. 2012 DOI: 10.1002/anie.201201822 Summary: What’s your blood type? Chances …
The cocoons, the silkworm itself, and the produced silk become colored when dye is incorporated into the silkworm feed. The concentration of dye in the produced silk changes based on how hydrophobic the dye is (increasing partition coefficient).
I hope most of us have experienced the wonder of watching fireflies lighting up on a warm summer evening.
This article demonstrates the metabolic labeling of bacteria without genetic engineering.
Title: Photoreversible Patterning of Biomolecules within Click-Based Hydrogels Authors: Cole A. DeForest and Kristi S. Anseth Journal: Angewandte Chemie International Edition Affiliation: Chemical & Biological Engineering, University of Colorado and the Howard Hughes Medical Institute Hydrogels have become an important category of materials for studying cell growth and development. Scientists are able to control …
To do the biological study of how particular (good) chemicals like antioxidants affect people, there needs to be a quick, reliable, and consistent way to measure those chemicals in humans. Furthermore, a good method would test for multiple chemicals, because the health benefits from some chemicals only exist in the presence of others (phenolic acids and flavonoids in this case). The authors of this paper demonstrate a gas-chromatography mass-spectrometry (GC-MS) method to investigate how some of the chemicals present in cranberries (from cranberry juice) go into your bloodstream after you ingest them.
