... configuration. At a sufficiently high speed a new instability occurs and the drogue oscillates vertically with a period much less than its period of rotation. The stability of rotating cable and string systems is important for textile yarn spinning systems, and when drogues are towed by aircraft in circular pat...Scientists detect probable genetic cause of some Parkinson's disease cases
...radykinesia, or slowness of movement; and postural instability or impaired balance and coordination. Patients may also have difficulty walking, talking, or completing other simple tasks. The disease is both chronic and progressive. Incidence of the disease increases with age, with an average onset at about 60 ye...Genetic testing for Parkinson's disease on the horizon
...r, slowness of movement, muscle rigidity, postural instability and impaired balance and coordination. Vincenzo Bonifati (Erasmus Medical Centre, Rotterdam, Netherlands) and colleagues analysed the LRRK2 gene in 61 families with Parkinson's disease. The investigators found that individuals in 4 unrelated familie...UCSD discovery shows how embryonic stem cells perform 'quality control' inspections
...er cells. Unrepaired DNA damage will cause genetic instability and, ultimately, cellular transformation into cancer cells." Xu and his team made their discovery while working with embryonic stem cell lines from mice, which possess the same known properties and capabilities as human embryonic stem cells.

...tion may become cancerous because of the resulting instability in PTEN. This would represent a new tumorigenic pathway that is not due to a defective PTEN gene but rather a loss of PTEN function caused by PICT-1. If this is the case, then this new type of tumor may be treated with rapamycin or related drugs th...Rutgers-led research offers new clues in the genetic mysteries of maize
