Scientists map one of biology's critical light-sensing structures

...r graduate student Jeremiah Wagner, caps a 30-year quest by biologists to drill down to the inner workings of how plants, fungi and bacteria use light to guide their development. It will likely spur a rush by scientists to capitalize on the new knowledge and may one day lead to such things as plants whose...

Recreating 'Flowers for Algernon' with a happy ending

...long-term use. "It became something of a Quixotic quest -- an impossible dream," Silva admitted. "We thought, 'Wouldn't it be nice to find a drug that is already FDA-approved, safe for lifetime use and could be tested in mice and humans with NF1?' Fortunately, our optimism was rewarded." It took a medi...
