Two from one: Pitt research maps out evolution of genders from hermaphroditic ancestors
Research from the University of Pittsburgh published in the Nov. 20 edition of Heredity could finally provide evidence of the first stages of the evolution of separate sexes, a theory that holds that males and females developed from hermaphroditic ancestors. These early stages are not completely understood because the majority of animal species developed into the arguably less titillating separate-sex state too long ago for scientists to observe the transition.

Scientists discover concealed glaciers on Mars at mid-latitudes
Vast Martian glaciers of water ice under protective blankets of rocky debris persist today at much lower latitudes than any ice previously identified on Mars, says new research using ground-penetrating radar on NASA’s Mars Reconnaissance Orbiter. The discovery is an encouraging sign for scientists searching for life beyond Earth. The water ice might also provide a useful resource for human explorers visiting the red planet.

Scientists are high on idea that marijuana reduces memory impairment
The more research they do, the more evidence scientists find that specific elements of marijuana can be good for the aging brain by reducing inflammation there and possibly even stimulating the formation of new brain cells. It suggests that developing a legal drug that contains certain properties similar to those in marijuana might help prevent or delay the onset of Alzheimer’s disease. Though the exact cause of Alzheimer’s remains unknown, chronic inflammation in the brain is believed to contribute to memory impairment.
