Biotechnology's newest chemical tool

... pulled by a DC motor. So the proximal, medial and distal phalanges, those bones between your finger knuckles, are all driven by the same tendon. This approach is called underactuation as there are more Degrees of Freedom than Degrees of Movement (motors); it means the prosthesis has a self-adaptive grasp. ...

Rice bioengineers pioneer techniques for knee repair

...proach to grow the entire articular surface of the distal femur. Each of these unbroken samples were tailored three-dimensionally to fit a specific rabbit femur. "If you told me 10 years ago that we would be making entire articular end caps via self assembly I would have said you were crazy," said Athanasi...

...mal joint near where the arm meets the body, and a distal joint near the suckers that have grasped the food. The medial joint typically exhibits the most movement during food retrieval. The authors also found evidence that, like certain types of human arm movements, octopus fetching movements are controll...

Non-coding RNAs help silence the mammalian transcription

...ome. In the mouse, a cluster of nine genes on the distal end of the number 7 chromosome is imprinted. Dr. Tilghman and colleagues made a series of targeted alterations to ascertain which sequences are responsible for their paternal-specific silencing. The researchers show that this imprinted gene silencing...
