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.

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
Transistors based on carbon nanostructures: what sounds like a futuristic dream could be reality in just a few years' time. An international research team working with Empa has now succeeded in producing nanotransistors from graphene ribbons that are only a few atoms wide, as reported in the current issue of the trade journal "Nature Communications."
Graphene ribbons that are only a few atoms wide, so-called graphene nanoribbons, have special electrical properties that make them promising candidates for the...
