Movement of nanomaterials in food chain
|
New research in Nature Nanotechnology shows that while engineered nanomaterials can be transferred up the lowest levels of the food chain from single celled organisms to higher multicelled ones, the amount transferred was relatively low and there was no evidence of the nanomaterials concentrating in the higher level organisms. The preliminary results observed by researchers from the National Institute of Standards and Technology suggest that the particular nanomaterials studied may not accumulate in invertebrate food chains.

Researchers Suggest Quantum Dots as Media for Teleportation
|
According to recent research, tiny clusters of atoms known as quantum dots may be excellent media for quantum teleportation, a physics phenomenon in which information – in the form of a quantum state, a very specific mathematical “signature” of an atom – can be transmitted almost instantaneously to a distant location without having to physically travel through space. Teleportation is one facet of quantum information science, a developing field that could have a major impact on computing and communications.

40% efficient solar cells to be used for solar electricity
|
Scientists from Spectrolab, Inc., a subsidiary of Boeing, have recently published their research on the fabrication of solar cells that surpass the 40% efficiency milestone—the highest efficiency achieved for any photovoltaic device. Their results appear in a recent edition of Applied Physics Letters.

Mathematicians and number buffs have their records. And today, an international team has broken a long-standing one in an impressive feat of calculation.
On March 6, computer clusters from three institutions – the EPFL, the University of Bonn and NTT in Japan -- reached the end of eleven months of strenuous calculation, churning out the prime factors of a well-known, hard-to-factor number that is a whopping 307 digits long.

The Mathematics of Natural Motion
|
Two mathematical equations (represented by red lines) can describe all the observed motions of the bacterium Listeria monocytogenes (blue or green lines). Mutant strains do not move in ways predicted by the equations, allowing researchers to identify and study non-standard microbes. |
