Hussein put in place to divert the water from the marshes. This has resulted in 20 to 30 per cent of the once-dried land being covered in water again. Canadian scientists haven't been able to enter Iraq to study the marshes, but they have held scient...

Scientists find genetic pathway that could lead to drugs for kidney disease
...nd signals to the kidney cells that line the small canals
called tubules. It is the loss of cilia function that leads to polycystic kidneys. "With polycystic kidneys, these tubular cells think they have to repair an injury, and they 'repair' by forming lots of cysts," said Weimbs. The disease is triggere...

that the researchers stimulated to control walking and balance detect rotational movements of the head, not the direction of gravity. These findings therefore show that sensing movement is crucial for our upright posture. The findings support inte...
