Exotic Insulator May Hold Clue to Key Mystery of Modern Physics

Experiments using laser light and pieces of gray material the size of fingernail clippings may offer clues to a fundamental scientific riddle: What is the relationship between the everyday world of classical physics and the hidden quantum realm that obeys entirely different rules?

For the First Time, Scientists Catch Water Molecules Passing the Proton Baton

2006-01-28_Drop-impact-300x289.jpeg

Water conducts electricity, but the process by which this familiar fluid passes along positive charges has puzzled scientists for decades. But in a paper published in the Dec. 2 in issue of the journal Science, an international team of researchers has finally caught water in the act — showing how water molecules pass along excess charges and, in the process, conduct electricity.

How to Ensure the Safety of Cosmetics

cosmeticsThumb.jpg

In recent years, environmental groups have been calling out cosmetic preservatives as suspected endocrine disruptors, cancer-causing agents and skin irritants. The campaigns have resulted in new restrictions on certain preservatives. But, as reported in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, the shrinking list of approved preservatives is having unintended consequences.

Mimicking Bug Eyes Could Brighten Reflective Signs and Clothes

That bright, reflective coating used on road signs, bicycles and clothing are important safety measures at night. They help drivers get to their destinations while avoiding bicyclists and pedestrians in low-light conditions. Now, inspired by the structure of insect eyes, scientists have developed new materials that could improve the color and effectiveness of these safeguards. Their report appears in the ACS journal Langmuir.

Creating New Physical Properties in Materials

A collaborative effort between research groups at the Technical University of Freiberg and the University of Siegen in Germany demonstrates that the physical properties of SrTiO3, or strontium titanate, in its single crystal form can be changed by a relatively simple electrical treatment.

Ultrafast Imaging Reveals Existence of 'Polarons'

d3811016-720px.jpg

UPTON, NY—Many people picture electrical conductivity as the flow of charged particles (mainly electrons) without really thinking about the atomic structure of the material through which those charges are moving. But scientists who study "strongly correlated electron" materials such as high-temperature superconductors and those with strong responses to magnetism know that picture is far too simplistic.

Sparkling Firework Droplets

In Japan, many adults hold fond childhood memories of fireworks as a symbol of the summer season. Senko-hanabi, which translates to “sparkling fireworks,” emit a small fireball with streaks of light akin to pine needle structures. As one of the most popular hand-held fireworks since the early Edo period, from 1603 to 1868, they’re renowned for fragile beauty accompanied by a soothing sound. During the 69th DFD meeting, researchers will describe work uncovering the liquid dynamics at play behind Senko-hanabi’s beauty.

Understanding the Mechanics of Breastfeeding

Breastfeeding is a topic that creates discussion and at times even controversy. However, some basic questions about its biology still remain. For instance, does successful infant feeding depend on the mechanics of the breast and, conversely, does breast health depend on breastfeeding? It has been virtually impossible to study these complex dynamics and the delicate interplay that makes breastfeeding possible, but a pair of researchers are working together to build a biomimetic breast that will allow scientists to study how the breast behaves during its primary function: infant feeding.

The research team around Anton Zeilinger has succeeded in breaking two novel records while experimenting with so-called twisted particles of light. In one experiment, the scientists could show that the twist of light itself, i.e. the screw-like structure, is maintained over a free-space propagation of 143 kilometers, which could revolutionize future data transmission.
