Journal of the American Chemical SocietyOregon lab changes game for synthesizing new materials University of Oregon chemist David C. Johnson likens his lab's newly published accomplishments to combining two flavors of ice cream and churning out thousands of flavors to appeal to any taste bud. In reality, he is referring to his method of synthesizing thousands of new compounds with ultra low thermal conductivity.

Nature CommunicationsUsing gold and light to study molecules in water Thanks to a new device that is the size of a human hair, it is now possible to detect molecules in a liquid solution and observe their interactions. This is of major interest for the scientific community, as there is currently no reliable way of examining both the behavior and the chemical structure of molecules in a liquid in real time.Developed at Boston University, the process brings together infrared detection techniques and gold nanoparticles. The results have been published in Nature Communications. Contact: Pessina Laure-Anne

Nano LettersChemists develop innovative nano-sensors for multiple proteins Chemists at Johannes Gutenberg University Mainz have developed a new method for parallel protein analysis that is, in principle, capable of identifying hundreds or even thousands of different proteins. It could be used to detect the presence of viruses and identify their type in tiny samples. At the same time, it is very cost-effective and quick. Contact: Dr. Carsten Sönnichsen

Review of Scientific InstrumentsHardness, in depth Scientists have now built a machine that sets a new standard of accuracy for testing a material's hardness, which is a measure of its resistance to bumps and scratches. The new machine is called the Precision Nanoindentation Platform, or PNP. Contact: Jason Socrates Bardi

Nature NanotechnologyMolecular robots can help researchers build more targeted therapeutics Many drugs such as agents for cancer or autoimmune diseases have nasty side effects because while they kill disease-causing cells, they also affect healthy cells. Now a new study has demonstrated a technique for developing more targeted drugs, by using molecular "robots" to hone in on more specific populations of cells.

Advanced MaterialsQuantum of sonics: Bonded, not stirred Researchers at McGill University have discovered a new way to join materials together using ultrasound. Ultrasound -- sound so high it cannot be heard -- is normally used to smash particles apart in water. In a recent study, the team of researchers, led by McGill professor Jake Barralet, from the faculties of Dentistry and Medicine, found that if particles were coated with phosphate, they could instead bond together into strong agglomerates, about the size of grains of sand. Their results are published in the journal Advanced Materials. Contact: Cynthia Lee

NatureNature: Elementary physics in a single molecule A team of physicists has succeeded in performing an extraordinary experiment: They demonstrated how magnetism that generally manifests itself by a force between two magnetized objects acts within a single molecule. This discovery is of high significance to fundamental research and provides scientists with a new tool to better understand magnetism as an elementary phenomenon of physics. The researchers published their results in the latest issue of Nature Nanotechnology. Contact: Monika Landgraf

Physical Review LettersThe ferromagnetic Kondo effect A group of physicists that includes scientists of the International School for Advanced Studies of Trieste have shown how to obtain a particular case of a physical effect -- so far never observed in reality -- whose studies have earned a Nobel Prize. The scientists have also observed the response of the material subject to such effect. These observations will provide precious indications to the experimental physicists in order to verify, in the future, their theory. Contact: Federica Sgorbissa
