Simple enrichment reduces boredom and improves the welfare of farmed dairy cows.
In a new study from JDS Communications, researchers demonstrated that adding new sailing buoys to their pens significantly reduced boredom-related behavior in two dairy cows. Credit: Alison L. Russell Understanding dairy cow behavior has been a hot topic in dairy science research in recent decades. In a special issue of JDS Communications devoted to dairy cow behavior, new research highlights…

Simple table salt powers new sticky polymer technology
Graphical summary. Credit: Journal of the American Chemical Society (2024). DOI: 10.1021/jacs.4c06877 Adhesives are everywhere, from household tapes to adhesives in cars and electronic devices. Research into stronger, more accommodating adhesives is currently underway, but ultimately involves adding small amounts of salt to two special polymer components known as polyzwitterions (PZIs). It may be. New research by a FAMU-FSU School…

A simple model system can disassemble fibrils and study therapeutic drugs for neurodegenerative diseases
Credit: Journal of the American Chemical Society (2024). DOI: 10.1021/jacs.4c11285 The causes of many diseases, such as Alzheimer’s disease and Parkinson’s disease, are found at the molecular level, or proteins, in our bodies. In healthy systems, these proteins are responsible for numerous physiological functions. They can also assemble into groups of many proteins to perform specific tasks. Once the job…

Periodic nano/microstructures can be printed on glass using a simple technique
PDMS-based tape test to evaluate the robustness of Ar plasma post-treatment patterns. a) Photographs of Ar plasma post-treatment patterns before and after robustness test. Bring the original PDMS slab into contact with the printed pattern and then peel it off. Repeat this cycle up to five times and observe the surface using a laser microscope immediately after each cycle. b)…
