Magnetic fields of Mars and Saturn
It is thought planets have dynamos in their centre. This explains the intensity and geometry of the magnetic fields found on the surface. The dynamo is in the form of a fluid sphere of molten iron which is churning around producing electric currents and magnetic fields. But Mars has a strange field. Only the southern hemisphere has a strong magnetic field, emanating from the crust. Secondly, this crustal field is very strong, about ten times what’s found on Earth or other rocky planets. This is one of a range of amazing anomalies with Mars. Saturn has other problems. Its fields are too perfect. Sabine Stanley explains.

NPR Science Friday : Can scientific reasoning be taught?
Scientific reasoning is essential to a successful career in science. But research in the journal Science claims this skill can’t be learned through memorization of facts alone. Author Lei Bao explains the findings, and how teachers can apply them in the classroom.

Science Education in the 21st Century: Using the Tools of Science to Teach Science
Nobel Laureate Dr. Carl Wieman directs the Carl Wieman Science Education Initiative at the University of British Columbia and the Colorado Science Education Initiative.
(Sep 22, 2008 at Cornell University)
Wieman emphasizes the importance of making science education effective and relevant for a large and diverse population. The approach, he says, is to transform how students understand and use science, and this calls for teaching them to actually think like scientists.

Music on Your Brain
Music is more than just pitch and rhythm, timbre and tempo. Music can comfort. Or annoy. It helps us celebrate – and mourn. Music can foster a sense of group identity. (Consider national anthems.)
Are human beings hard-wired to enjoy music? What role did music play in the evolution of human societies? What would life be without music?
In this World Science Forum, we talk to Daniel Levitin, a neuroscientist at McGill University. He’s an expert on music cognition and the author of two books: This is Your Brain on Music and The World in Six Songs.
Levitin argues that music is at the heart of human nature. The World’s Rhitu Chatterjee spoke with Levitin for The World Science Podcast.
