Damien Clarke is a GIF maker from Melbourne, Australia who posts under the name 12gon. All of his graphics are generated entirely by writing code, inputting vertex coordinates, animating values using different algorithms and choosing colours by typing in hex values. This is all done in a 2D/3D graphics library he wrote for a different purpose in an Adobe AIR app.
In a new study from the University of Pennsylvania and National Institute of Dental and Craniofacial Research, scientists used an innovative technique to study how cells move in a three-dimensional matrix, similar to the structure of certain tissues, such as the skin. They discovered an entirely new type of cell movement whereby the nucleus helps propel cells through the matrix like a piston in an engine, generating pressure that thrusts the cell’s plasma membrane forward.
"Our work elucidated a highly intriguing question: how cells move when they are in the complex and physiologically relevant environment of a 3-D extracellular matrix," said Hyun (Michel) Koo, a professor in the Department of Orthodontics at Penn’s School of Dental Medicine. "We discovered that the nucleus can act as a piston that physically compartmentalizes the cell cytoplasm and increases the hydrostatic pressure driving the cell motility within a 3-D matrix."

They found that, in this environment, the cells’ nuclei operate like an engine’s piston to push the cell forward. Credit: University of Pennsylvania/NIDCR
California inches closer to statewide ban on disposable plastic bags
In California, where numerous municipalities have already given single-use plastic bags the boot, lawmakers approve a statewide bag ban.
[I]t’s been clear for years that destroying public education is where charters, vouchers, and online schools are taking us under the guise of helping the disadvantaged. But one rarely sees it put so bluntly as this week. The WaPo’s Valerie Strauss quotes the Dayton Area Chamber of Commerce’s vice president of public policy and economic development:
“The business community is the consumer of the educational product. Students are the educational product. They are going through the education system so that they can be an attractive product for business to consume and hire as a workforce in the future.”
Yup. Like Robocop, your kids are product.
