Zenna Atkins, the chairman of the Office for Standards in Education (Ofsted), has raised some eyebrows by saying that, "every school should have a useless teacher." She stresses that schools shouldn't seek out or tolerate bad teaching, but thinks bad teachers provide a valuable life-lesson. From the article: "... on Sunday Ms Atkins told the BBC that schools needed to reflect society, especially at primary level. 'In society there are people you don't like, there are people who are incompetent and there are often people above you in authority who you think are incompetent, and learning that ability to deal with that and, actually surviving that environment can be an advantage.'"

Calopteryx writes "New Scientist has a story on a self-replicating entity which inhabits the mathematical universe known as the Game of Life. 'Dubbed Gemini, [Andrew Wade's] creature is made of two sets of identical structures, which sit at either end of the instruction tape. Each is a fraction of the size of the tape's length but, made up of two constructor arms and one "destructor," play a key role. Gemini's initial state contains three of these structures, plus a fourth that is incomplete. As the simulation progresses the incomplete structure begins to grow, while the structure at the start of the tape is demolished. The original Gemini continues to disassemble as the new one emerges, until after nearly 34 million generations, new life is born.'"

Biologists can't speak on the effectiveness of Calvin Klein Obsession for Men on the cougars at your local bar, but they do know that jaguars love it. Rony Garcia and Jose Moreira from the Wildlife Conservation Society's (WCS) Jaguar Conservation Program use the cologne to attract jaguars in the jungles of Guatemala. "The method we are using to study the jaguars here in Guatemala is a non-invasive method which is based on photographing the individuals by using camera traps," Moreira says. "It has been very useful using Obsession (for Men) to get the jaguars in front of these camera traps ... and that allows us to estimate with greater confidence the genders and the numbers that live in each studied site."
