9:26 AM | Why start from scratch when you can recycle and adapt?
Leaf development is such a fascinating topic, because it reveals the molecular processes the are involved in pattern formation. Interestingly, several genes and small molecules (e.g., auxin) are used repeatedly during the initiation and elaboration of leaves. A pair of papers out in Plant Cell highlights this thrifty genetic strategy. In the first, we see how the development of the ligule in a maize leaf involves the redeployment of several genes that are involved in leaf initiation, a process […]

11:55 PM | Obama Announces Plans to Normalize Relations With Cuba and Open Embassy in Havana
In 1960, the U.S. enacted a series of economic regulations, travel restrictions, and international legal penalties on Cuba in response to Fidel Castro’s nationalization (government seizure) of American property. The embargo’s long-term goal was to create a more democratic government in Cuba, but many critics say that the embargo has failed to accomplish this goal and has only served to hurt the Cuban people. Back in October, the UN General Assembly voted overwhelmingly in favor of a […]

6:13 PM | Utah Man Videos A MantidFly That Looks Like Something From Science-Fiction
Utah resident Ed Kern may have just captured the best video to date of a Mantidfly. Kern, who said he found the creature in his backyard hanging out casually on the fence, used his Canon SX-20IS to create an amazing video of the beautiful insect. The video is high-definition, and may seem fake at first due to the unusual nature of the insect, but this is a real video and a real living insect. Check it out below… Mantidflies, belonging to the

12:04 PM | Thinking about how girls think about themselves
Self-perception colours our choices, limits or drives our ambitions, and affects how we come across to others. So role models and cultural icons matter when it comes to the messages we give our children. If we tell boys not to cry, they can grow up feeling they are wimps if they let their emotions overspill.
