Microbes take their vitamins, for the good of science: Scientists exploit organisms' needs in order to track 'vitamin mimics' in bacteria
Science Daily / Posted 20 days ago
Now scientists at the Department of Energy's Pacific Northwest National Laboratory have made a "vitamin mimic" -- a molecule that looks and acts just like the natural vitamin to bacteria, but can be tracked and measured by scientists in live cells.... Read more

How seashells get their strength: Study shows how calcium carbonate forms composites to make strong materials such as in shells and pearls
Science Daily / Posted a month ago
The results show that such clumps become incorporated via chemical interactions with atoms in the crystals, an unexpected mechanism based on previous understanding. By providing insight into the formation of natural minerals that are a composite of... Read more

Study shows how calcium carbonate forms composites to make strong materials such as in shells and pearls
PhysOrg / Posted 1 months ago
When calcium carbonate crystallizes into hard shells, it incorporates soft bits of proteins to add strength. Research done in the lab shows how this might happen, and why it works. Credit: Wikipedia/ Public Domain Seashells and lobster claws are hard... Read more
