An outgrowth of the 1960s alternative school movement, homeschooling, is on the upswing in the United States, and a Penn State researcher is trying to piece together a snapshot of the movement where in many cases, states require little record keeping.
"Until the 1980s, most of the students kept out of regular schools to be homeschooled were breaking state laws," says JoAnn C. Vender, graduate student in geography. "In research on the geography of education, there are very few studies on home schooling because the data are hard to pin down. Homeschoolers represent a significant, but under-studied segment of the education universe – estimated at about 1.1 million students, about 20 percent of the privately-schooled population in the U.S."
The homeschooling movement was fueled by fundamentalist Christians and other religious groups who adopted the practice with vigor in the 1980s, pushing states to legalize the practice in the 80s and 90s.

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
