First Image Made of an Atom Spinning Physicists have discovered a way to play with matter on a subatomic scale, reaching into atoms to manipulate the spin of electrons. What's more, the scientists were able to capture the first images of the action with a special microscope. Spin is one of three basic properties of electrons, along with charge and mass. In the new study, researchers figured out how to change the spin of electrons in cobalt atoms (a metallic element with 27 protons and 27 electrons). On scales this small, it's impossible to take a picture using visible light, as the wavelengths are bigger than the objects they would reflect off of. To change the spin of the electrons in the cobalt atoms, Kubetzka and colleagues placed the atoms on a surface made of the element manganese. "By precisely positioning the cobalt atoms on the manganese surface, we can tune the spin-direction of the cobalt atoms," said co-researcher Saw-Wai Hla of Ohio University's Nanoscale and Quantum Phenomena Institute.

Silicon Chips Wired With Nerve Cells Could Enable New Brain/Machine Interfaces It's reminiscent of Cartman's runaway Trapper Keeper notebook in that long-ago episode of South Park, but researchers at the University of Wisconsin-Madison may be scratching the surface of a new kind of brain/machine interface by creating computer chips that are wired together with living nerve cells. A team there has found that mouse nerve cells will connect with each other across a network of tiny tubes threaded through a semiconductor material. It's not exactly clear at this point how the nerve cells are functioning, but what is clear is that the cells seem to have an affinity for the tiny tubes, and that alone has some interesting implications. To create the nerve-chip hybrid, the researchers created tubes of layered silicon and germanium that are large enough for the nerve cells' tendrils to navigate but too small for the actual body of the cell to pass through. What isn't clear is whether or not the cells are actually communicating with each other they way they would naturally.
Workshops | Inquiry in Action Learn how to incorporate inquiry-based scientific investigations into your elementary or middle school science curriculum through the Inquiry Matters onsite workshop. This hands-on workshop, given by authors of Inquiry in Action engages teachers in the elements of inquiry. What will I learn in the Inquiry Matters workshop? Inquiry Matters workshop participants experience the process of scientific discovery as they contribute their own ideas, help design experiments, and discuss possible explanations for their observations. Workshop participants will: Learn what inquiry is and how to incorporate inquiry into a science curriculum Conduct science investigations that build physical science and inquiry knowledge and skills Get background information and activities highlighting physical properties and change, chemical change, states of matter, and density Receive a printed copy of everything taught in the workshop—and much more—with the book Inquiry in Action.
