Cockroach-like robot leads new research effort

... insects. At the same time, they will conduct biomechanical and neurological experiments on insects and develop mathematical models to improve the robot. This multi-pronged approach will allow them to uncover the neural and muscular control and feedback loops that lead to the remarkably similar patterns of wh...

Bracing is less effective in overweight teens with scoliosis

...y. Braces exert their effects on the spine through biomechanical forces, which need to be of sufficient magnitude to create and sustain curve correction. However, because overweight patients have more and thicker soft tissue and surface area, researchers believe the effects may be compromised. "It's possible that...

Improving bone implant technology

...o this, bioengineers need to determine the optimal biomechanical situation (for example, amount and timing of weight loading) for bone healing around implants. "The cellular and molecular rules that govern how bone adapts to a loaded or unloaded implant have not been as clearly determined as we would like," said B...

"It is not possible to simulate the motions and functions of knee implants without the advanced software tools like Professor Fregly has develop...

University of Pittsburgh scientist discusses blood cell damage from biomedical devices

...ty, Dr. Kameneva said. There also is evidence that biomechanical devices decrease the number of white blood cells and platelets to below normal levels, possibly leading to an increased risk of infection or stroke. "There are abnormally high shear stresses and turbulence within artificial organs, and even blood ce...

MIT probes cartilage on nanoscale

...ed to each other, and how they lead to macroscopic biomechanical properties," the team writes. Ortiz notes that "since multiple forces acting in tandem are a hallmark of most other areas of biophysics, polymer physics, and surface science, this new methodology will have far-reaching implications. In the near futur...

Human ancestor Australopithecus did indeed walk upright

...o gross size differences but are more likely to be biomechanical differences. "Australopithecines were likely habitual bipeds, but differed in overall spinal mechanics and efficiency," he said. "They are also important because they show that all anatomical regions should be considered together in behavioral rec...

Tyrannosaurus rex probably could not run fast, scientists say

... but emphasizes biomechanics. By varying different biomechanical parameters - posture, center of mass, leg weight and total weight - the researchers can quickly quantify the physical forces exerted during movement and the amount of muscle needed to support various postures and speeds. They can create two-dimension...
