Article Synopsis
- Understanding the impact of climate change on host-parasite systems is crucial for predicting potential effects on ecosystems, economies, and human health.
- A study comparing thermal tolerance between a caterpillar host and two wasp species revealed that the caterpillar can withstand significantly higher temperatures than its parasitic and hyperparasitic wasps.
- Historical temperature records indicate that maximum daily temperatures in the area are approaching the critical limits for some species, suggesting that climate change could disrupt these interactions in unpredictable ways.
A simple method for preparing bio-functionalized soluble single-walled carbon nanotubes (SWNTs) is described. Different proteins such as bovine serum albumin (BSA), cytochrome c and horseradish peroxidase (HRP) were used to solubilize low functionality SWNTs in water aided by sonication. The unbound proteins were removed by column chromatography and the SWNT-protein conjugate was used as the sole anionic dopant in electropolymerization of polypyrrole from polymerization solution at pH above the isoelectric point of the protein to provide a negative charge.

The principle of the new biosensor is based on the enzyme-catalyzed hydrolysis of the nerve agents and amperometric detection of the thiol-containing hydrolysis products at carbon nanotube-modified screen-printed electrodes. Demeton-S was used as a nerve agent mimic.
