In Tight Spaces, Sperm Slither Rather Than Shimmy

Sperm usually swim in a 3D shimmy: a spiral wave travels down the whippy flagellum and rotates its head in a circle around its long axis.

Can We Turn Stem Cells Into Eggs?

Northeastern University biologist Jonathan Tilly is certain he’s found egg-making stem cells in adult mice.
