When Physics Gives Evolution a Leg Up by Breaking One
Physics Evolution a Leg Up Breaking One
2017/12/18
Genetic mutation may drive evolution, but not all by itself. Physics can be a powerful co-pilot, sometimes even setting the course.In a new study, physicists and evolutionary biologists at the Georgia...
A probe invented at Rice University that lights up when it binds to a misfolded amyloid beta peptide — the kind suspected of causing Alzheimer’s disease — has identified a specific binding site on the...

Cell Modeling Tool Complex Calculations User-Friendly
2017/10/25
Programming a molecular biology experiment can be similar to playing Sudoku; both are simple if you’re working with only a few molecules or a small grid, but they explode in complexity as they grow. N...
Kinesins ignore weak forces as they carry heavy loads（图）
Kinesins ignore weak forces carry heavy loads
2017/10/25
If you’re the motor protein up front, be prepared to do the heavy pulling.That’s one conclusion from a Rice University-led study of the mechanisms that drive kinesins, motor proteins that carry cargo ...
