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

Nature Methods

Need a really small number?

Biomedical engineer Yonggang Ke‘s “DNA origami” artwork appears on the cover of NKe-image-300x265ature Methods, as part of a celebration of the journal’s 10th anniversary. Ke designed self-assembling DNA strands that would form a cylinder and a ring structure, let them assemble, and obtained images with transmission electron microscopy. The height of the final image is 120 nanometers, smaller than the wavelengths of visible light and about the size of an influenza or HIV virion.
