| New insights into the assembly of photosynthetic membranes Posted: 02 Jul 2021 12:43 PM PDT An international study has elucidated the structure of a protein that is required for the assembly and stability of photosynthetic membranes. |
| Neurobiology: How mice see the world Posted: 02 Jul 2021 12:43 PM PDT Researchers have developed an open-source camera system that images natural habitats as they appear to rodents. |
| A globally important microbial process hidden on marine particles Posted: 02 Jul 2021 12:43 PM PDT Nitrogen is essential for all life on Earth. In the global oceans however, this element is scarce, and nitrogen availability is therefore critical for the growth of marine life. Some bacteria found in marine waters can convert nitrogen gas (N2) to ammonia (known as N2 fixation), and thereby supply the marine food web with nitrogen. |
| Solving a long-standing mystery about the desert's rock art canvas Posted: 02 Jul 2021 12:42 PM PDT Petroglyphs are carved in a material called rock varnish, the origins of which have been debated for years. Now, scientists argue it's the result of bacteria and an adaptation that protects them from the desert sun's harsh rays. |
| Striking a balance: Trade-offs shape flower diversity Posted: 01 Jul 2021 08:26 AM PDT Flower generalization has often been viewed as a suboptimal solution to managing the needs of different visitors. Researchers have developed a framework to examine flower-animal interactions and how different types of visitor-mediated trade-offs affect flower evolution. They found that mitigating trade-offs can lead to novel combinations of traits that enhance floral diversity. These findings could explain the discrepancy between observed flower visitors and those predicted based on a flower's traits. |
| Posted: 30 Jun 2021 09:54 AM PDT Increasing our understanding of cellular processes requires information about the types of biomolecules involved, their locations, and their interactions. This requires the molecules to be labeled without affecting physiological processes (bioorthogonality). This works when the markers are very quickly and selectively coupled using small molecules and 'click chemistry.' A team of researchers has now introduced a novel type of click reaction that is also suitable for living cells and organisms. |
