Roberto Carlos' free kick goal against France in 1997's Tournoi de France is thought by many to have been the most skilful free kick goal - from 35m with a powerful curling banana trajectory - ever scored; but by others to have been an incredible fluke.

Purdue University researchers have developed a new type of pump for drug-delivery patches that might use arrays of "microneedles" to deliver a wider range of medications than now possible with conventional patches.

Speakers made from carbon nanotube sheets that are a fraction of the width of a human hair can both generate sound and cancel out noise -- properties ideal for submarine sonar to probe the ocean depths and make subs invisible to enemies. That's the topic of a report on these "nanotube speakers," which appears in ACS' Nano Letters, a monthly journal.

To watch a magician transform a vase of flowers into a rabbit, it's best to have a front-row seat. Likewise, for chemical transformations in solution, the best view belongs to the molecular spectators closest to the action.

A new experiment proposed* by physicists at the National Institute of Standards and Technology (NIST) may allow researchers to test the effects of gravity with unprecedented precision at very short distances—a scale at which exotic new details of gravity's behavior may be detectable.

"There's an app for that." To a cadre of scientists, the familiar phrase will soon mean they can enter a specific RNA from baker's yeast into their iPhone and see a depiction of its two-dimensional structure - thanks to a new technology developed by scientists at Stanford University.

Researchers describe how to carry out the first experimental test of string theory in a paper published tomorrow in Physical Review Letters.

Two new groundbreaking scientific papers by researchers at UC Santa Barbara demonstrate the synthesis of nanosize biological particles with the potential to fight cancer and other illnesses. The studies introduce new approaches that are considered "green" nanobiotechnology because they use no artificial compounds.

Rice University scientists have created the first two-terminal memory chips that use only silicon, one of the most common substances on the planet, in a way that should be easily adaptable to nanoelectronic manufacturing techniques and promises to extend the limits of miniaturization subject to Moore's Law.

With the advent of nanometer-sized machines, there is considerable demand for stable, precise tools to measure absolute distances and distance changes. One way to do this is with a plasmon ruler.
