Insights into Parkinson's balance problems

In PD, disorganized sensorimotor signals cause muscles in the limbs to contract, such that both a muscle promoting a motion and its antagonist muscle are Read more

Cajoling brain cells to dance

“Flicker” treatment is a striking non-pharmaceutical approach aimed at slowing or reversing Alzheimer’s disease. It represents a reversal of EEG: not only recording brain waves, but reaching into the brain and cajoling cells to dance. One neuroscientist commentator called the process "almost too fantastic to believe." With flashing lights and buzzing sounds, researchers think they can get immune cells in the brain to gobble up more amyloid plaques, the characteristic clumps of protein seen in Read more

Thyroid makes young mouse hearts grow

The entire heart muscle in young children may hold untapped potential for regeneration, new research suggests.

For decades, scientists believed that after a child’s first few days of life, cardiac muscle cells did not divide. Instead, the assumption was that the heart could only grow by having the muscle cells become larger.

Cracks were already appearing in that theory. But new findings in mice, published May 8 in Cell, provide a dramatic counterexample — with implications for the treatment of congenital heart disorders in humans. Read more
