Researchers demonstrate for the first time how light squeezes through small holes

May 08, 2008 | User rating: 4.4 / 5 after 41 vote(s) | pda version

How does light pass through a tiny hole" For the first time, Dr Aurele Adam and Prof. Paul Planken of Delft University of Technology, in conjunction with two South Korean and one German research groups, have succeeded in ...


A 'squeeze' in cuprates may explain superconducting temperatures

May 07, 2008 | User rating: 4.6 / 5 after 31 vote(s) | pda version

New experiments at Cornell have verified a theory that variations in the distance between atoms in cuprate superconductors account for differences in the temperature at which the material begins to superconduct. ...


NTT Introduces Commercial RedTaction 'Firmo' Security Device

May 05, 2008 | User rating: 4.1 / 5 after 13 vote(s) | pda version

NTT has developed a means to harness the Human Area Network to create Firmo. Firmo utilizes RedTaction which is a human body communication technology. It uses the surface of the human body as a transmission ...


Children more vulnerable to harmful effects of lead

May 04, 2008 | User rating: 5 / 5 after 2 vote(s) | pda version

Contrary to prevailing assumptions, children are more vulnerable to the harmful effects of lead exposure at the age of 6 than they are in early childhood, according to a Cincinnati Children’s Hospital Medical Center study ...


Spiraling nanotrees offer new twist on growth of nanowires

May 01, 2008 | User rating: 4.5 / 5 after 16 vote(s) | pda version

Since scientists first learned to make nanowires, the nano-sized wires just a few millionths of a centimeter thick have taken many forms, including nanobelts, nanocoils and nanoflowers.


Graphene-based gadgets may be just years away

Apr 30, 2008 | User rating: 4.8 / 5 after 59 vote(s) | pda version

Researchers at The University of Manchester have produced tiny liquid crystal devices with electrodes made from graphene – an exciting development that could lead to computer and TV displays based on this ...


Simulations may explain nanoparticles 'pinned' to graphene

Apr 24, 2008 | User rating: 4.5 / 5 after 24 vote(s) | pda version

It was hard to understand how a graphene sheet — a featureless, flat sheet of carbon atoms — lying on an equally featureless iridium surface, somehow converted itself into a kind of muffin tin that formed ...


Study Captures Brain's Activity Processing Speech

Apr 24, 2008 | User rating: 4.7 / 5 after 11 vote(s) | pda version

Rad, Lad. You might be able to hear the difference, but to many children and adults, these words sound exactly the same. The problem isn’t that they can’t hear the sounds. The problem is that they ...


Scientists discover exotic quantum state of matter

Apr 24, 2008 | User rating: 4.7 / 5 after 78 vote(s) | pda version

A team of scientists from Princeton University has found that one of the most intriguing phenomena in condensed-matter physics -- known as the quantum Hall effect -- can occur in nature in a way that no one ...


European light research opens door for optical storage and computing

Apr 24, 2008 | User rating: 3.7 / 5 after 7 vote(s) | pda version

The goal of replacing electronics with optics for processing data in computers is coming closer through cutting edge European research into the mysterious properties of “fast and slow” light. The long term aim is to boost ...

Nanobacteria – Are They Alive?

Apr 23, 2008 | User rating: 4.6 / 5 after 82 vote(s) | pda version

Tiny particles called nanobacteria have intrigued researchers in many ways since their discovery 20 years ago, but perhaps the most controversial question they pose is whether or not they are alive.


First-class protein crystals thanks to weightlessness on earth

Apr 23, 2008 | User rating: 5 / 5 after 1 vote(s) | pda version

Dutch chemist Paul Poodt has developed two attractive alternatives for allowing protein crystals to grow under weightless conditions. If the crystals are grown upside down in a strong magnetic field, fluid flows that disrupt ...
