| Posted: 15 Oct 2021 10:32 AM PDT Bacteria can store extra resources for the lean times. It's a bit like keeping a piggy bank or carrying a backup battery pack. One important reserve is known as cyanophycin granules, which were first noticed by an Italian scientist about 150 years ago. He saw big, dark splotches in the cells of the blue-green algae (cyanobacteria) he was studying without understanding either what they were or their purpose. Since then, scientists have realized that cyanophycin was made of a natural green biopolymer, that bacteria use it as a store of nitrogen and energy, and that it could have many biotechnological applications. |

| How long can fiber reinforced polymer sustain concrete structures? Scientists answer Posted: 14 Oct 2021 02:27 PM PDT One potential cost-effective way to sustain ageing concrete subjected to harsh environmental conditions is to externally coat the material with fiber reinforced polymer composites. But few studies have looked at the durability of such strengthening. Now, researchers from Korea and the USA conduct a 13-year long experiment to find out. |
| New theories and materials aid the transition to clean energy Posted: 14 Oct 2021 02:27 PM PDT Scientists have explored different approaches to catalysis, a chemical process that plays an essential role in biological reactions, as well as many industrial applications. Chemical catalysts have been used in a variety of human applications, ranging from pharmaceutical development to biodegradable plastics and environmentally safe fertilizers. They may also advance the development of green energy solutions to address the climate crisis. |
