Five Giant Impact Basins Reveal The Ancient Equator Of Mars
A Canadian researcher has calculated the location of Mars' ancient poles, based upon the location of five giant impact basins on the planet's surface. This suggests that the projectiles that caused the basins originated with a single source, an asteroid that disintegrated when it approached too close to Mars, and that the impacts trace the Martian equator at the time of impact. Lazy Eye: Older Children Can Benefit From Treatment For Childhood's Mo

New Route For Heredity Bypasses DNA
Scientists have uncovered a new biological mechanism that could provide a clearer window into a cell's inner workings. What's more, this mechanism could represent an "epigenetic"pathway -- a route that bypasses an organism's normal DNA genetic program -- for so-called Lamarckian evolution, enabling an organism to pass on to its offspring characteristics acquired during its lifetime to improve their chances for survival.
