| Snake venom complexity is driven by prey diet Posted: 19 Apr 2021 04:53 PM PDT Diversity in diet plays a role in the complexity of venom in pit vipers such as rattlesnakes, copperheads and cottonmouths. But new collaborative research found the number of prey species a snake ate did not drive venom complexity. Rather, it was how far apart the prey species were from each other evolutionarily. |
| DNA robots designed in minutes instead of days Posted: 19 Apr 2021 10:57 AM PDT Someday, scientists believe, tiny DNA-based robots and other nanodevices will deliver medicine inside our bodies, detect the presence of deadly pathogens, and help manufacture increasingly smaller electronics. Researchers took a big step toward that future by developing a new tool that can design much more complex DNA robots and nanodevices than were ever possible before in a fraction of the time. |
| NASA's Ingenuity Mars Helicopter succeeds in historic first flight Posted: 19 Apr 2021 07:01 AM PDT The small rotorcraft made history, hovering above Jezero Crater, demonstrating that powered, controlled flight on another planet is possible. |
