Quantum Cloaking Makes Molecules Invisible

KentuckyFC writes "An international team of physicists has applied the ideas of cloaking to the quantum world and worked out how to hide quantum objects such as molecules. In the quantum world, seeing is equivalent to detecting a quantum object. In the case of molecules, that means looking for the terahertz radiation they produce when they vibrate (abstract). By designing a 'quantum corral,' an elliptical nanostructures that absorbs terahertz waves at a precise frequency, the team says it is possible to hide molecules that emit at exactly that frequency. They say their quantum corral would be ideally suited to detecting molecules of specific species while ignoring others. And that may mean a new generation of molecular detectors on the horizon.

New Molecules With Many Branches Will Help Unleash Potential Of Nanotechnology

Materials science and the pharmaceutical industry could soon be revolutionized by emerging nanotechnologies based on designer molecules with long complex tree-and branch structures. Such molecules offer almost limitless scope for design of bespoke compounds for specific applications in disease therapy, for novel materials such as resins, as well as electronic displays, and energy storage. Almost every field involving design and synthesis of chemical compounds will be transformed by the arrival of technologies allowing nanoscale design of these branched molecules, known as hyperbranched polymers.

In conjunction with this fascinating exhibition, five speakers—all leaders in their fields—will address the science in everyday experiences and the promise and peril of discovery and innovation.

Scientists induce chirality in pre-biological molecules

(Nanowerk News) The basic molecules that make up all living things have a predetermined chirality or "handedness,” similar to the way people are right- or left-handed. This chirality has a profound influence on the chemistry and molecular interactions of living organisms. The creation of chirality from the elementary building blocks of matter is one of the great mysteries of the origin of life. Scientists at the U.S. Department of Energy's Argonne National Laboratory have discovered a way to induce this handedness in pre-biological molecules.

The Gene Is Having an Identity Crisis

gollum123 writes "New large-scale studies of DNA are causing a rethinking of the very nature of genes. A typical gene is no longer conceived of as a single chunk of DNA encoding a single protein. It turns out, for example, that several different proteins may be produced from a single stretch of DNA. Most of the molecules produced from DNA may not even be proteins, but rather RNA. The familiar double helix of DNA no longer has a monopoly on heredity: other molecules clinging to DNA can produce striking differences between two organisms with the same genes — and those molecules can be inherited along with DNA. Scientists have been working on exploring the 98% of the genome not identified as the protein-coding region. One of the biggest of these projects is an effort called the Encyclopedia of DNA Elements, or 'Encode.

But the greatest public interest in hyperbranched polymers is being generated by the medical potential, and another exciting application on this front could lie in their use to combat currently incurable diseases involving formation of plaques comprising wrongly folded proteins, such as Alzheimer's and prion diseases like CJD (Creutzfeldt-Jacob) disease. Highly branched molecules called dendrimers have already been shown capable of interacting with the proteins that combine together in plaques to cause these diseases, with evidence that this process can be inhibited, according to Barbara Klajnert from the University of Lodz in Poland in the workshop's first presentation.

New RNA Processing Mechanism And New Class Of Small RNAs

A very small fraction of our genetic material--about 2%-- performs the crucial task scientists once thought was the sole purpose of the genome: to serve as a blueprint for the production of proteins, the molecules that make cells work and sustain life. This 2% of human DNA is converted into intermediary molecules called RNAs, which in turn carry instructions within cells for protein manufacture.
