Tar pitch is thick and viscous, appearing to be almost solid as it slowly oozes. About 69 years ago, scientists set up a pitch-drop experiment to test exactly how long it would take for a single piece of the black substance to fall into a beaker. Now the experiment is finally over--the researchers h...
The binding power of DNA is well known – bases, bound into complementary pairs, are the building blocks of its double helix structure. Short sequences of DNA (15 to 40 base pairs in length) also chemically bond to small nanoparticles.
Better understanding of how surfaces attract or repel water could improve everything from power plants to ketchup bottles.
Ever wanted to make an object float? You don't need magic; you just need science. Researchers have used the power of sound to levitate objects and even move them around in midair. The findings could have huge implications for manufacturing processes, but are also just plain cool.
The use of graphene in telecommunications could dramatically accelerate internet speeds by up to a hundred times, according to new research.
This new material consists of many identical piece of grossly warped graphene, each containing exactly 80 carbon atoms joined together in a network of 26 rings, with 30 hydrogen atoms decorating the rim. These individual molecules, because they measure somewhat more than a nanometer across, are ref...
Random Lasers are tiny structures emitting light irregularly into different directions. Scientists at the Vienna University of Technology have now shown that these exotic light sources can be accurately controlled.
The most instantly recognizable image of an atom resembles a miniature solar system with the concentric electron paths forming the planetary orbits and the nucleus at the centre like the sun.
Objects that are smaller than the wavelength of thermal radiation cannot radiate heat efficiently. A generalized theory of thermal radiation has now been experimentally confirmed at the level of a single object at the Vienna University of Technology.
An electrical field applied to an ultra-thin layer of material can turn the polarisation of the beam as required. This produces an efficient transistor for light that could be miniaturised and used to build optical computers.
There are several different ways to trap light and now, researchers have designed another method to manage the feat. Scientists at MIT have developed a new system that pits light waves against light waves; the technique could have a wide variety of practical applications.
