A new study by a New York University professor suggests perceptual maturity in infants develops in the early months after birth as a result of piecing together fragments of the visual scene. The findings, published in the latest issue of Psychological Science, shed new light on our fundamental knowledge of how objects behave, giving weight to the scientific camp that argues such development is a "constructed" rather than an "innate" phenomenon.
Advocates of innate perception have based their conclusions on previous research, which typically measured perceptual abilities of four-month-olds and older infants. However, Scott Johnson, a professor of psychology and neural science who conducted the study, compared these abilities in both two- and four-month-olds, finding distinctions in the perceptual skills of the two groups.
"These results are only a part of the larger literature on perception, but this study does provide a very important piece of the puzzle," said Johnson. "It is now clear that theories of innate knowledge do not hold up under scrutiny. Instead, the developing visual system seems to build object representations from smaller, visible components, such as the visible portions of a partly occluded object. Isolating how and why this occurs should be the focal point of subsequent scholarship."

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
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...
