Shape of nanoparticles points the way toward more targeted drugs
A new study involving Sanford-Burnham's Erkki Ruoslahti, M.D., Ph.D., contributing to work by Samir Mitragotri, Ph.D., at the University of California, Santa Barbara, found that the shape of nanoparticles can enhance drug targeting. The study found that rod-shaped nanoparticles -- or nanorods -- as opposed to spherical nanoparticles, appear to adhere more effectively to the surface of endothelial cells that line the inside of blood vessels.

The secret life of knots
The scientific journal Macromolecules dedicates the cover of this month's issue (available online from June 11th) to a research coordinated by Cristian Micheletti of the International School for Advanced Studies (SISSA). Micheletti and his colleagues, that include Luca Tubiana (a former SISSA student, now working at the Josef Stefan Institute of Ljubljana) and Angelo Rosa (a researcher at SISSA) simulated the dynamics of the movements with which a polymer tends to knot.

Carbon nanotubes for molecular magnetic resonances
Researchers at ICFO have developed a new technique for measuring very weak forces on a molecular scale. Thanks to the use of carbon nanotubes, they have achieved the highest level of sensitivity to date. These results published in Nature Nanotechnology open the door for magnetic resonance imaging of individual molecules.

UC Santa Barbara study provides a new framework for understanding the energetics of ionic liquids
A new study by researchers at UC Santa Barbara provides clues into the understanding of the behavior of the charged molecules or particles in ionic liquids. The new framework may lead to the creation of cleaner, more sustainable, and nontoxic batteries, and other sources of chemical power. The research was published in an early online edition of the Proceedings of the National Academy of Sciences.

Promising material for lithium-ion batteries
Laptops could work longer and electric cars could drive farther if it were possible to further increase the capacity of their lithium-ion batteries. The electrode material has a decisive influence on a battery's capacity. So far, the negative electrode typically consists of graphite, whose layers can store lithium atoms. Scientists at the Technische Universitaet Muenchen have now developed a material made of boron and silicon that could smooth the way to systems with higher capacities.

New microfluidic method expands toolbox for nanoparticle manipulation
Researchers at the University of Illinois have developed a new flow-based method for manipulating and confining single particles in free solution, a process that will help address current challenges faced by nanoscientists and engineers. The "microfluidic trap" is capable of 2-D particle manipulation using the sole action of fluid flow.

Laser-brightened cirrus clouds
Intense laser light pulses increase the brightness of high cirrus clouds. Together with colleagues from Berlin and Geneva, climate researchers from Karlsruhe Institute of Technology have been investigating the interactions of laser light and ice clouds using the unique AIDA aerosol and cloud chamber on KIT's Campus North. The results of these studies have been published in the renowned Proceedings of the National Academy of Sciences of the United States of America.

Big multiple sclerosis breakthrough
A phase 1 clinical trial for the first treatment to reset the immune system of multiple sclerosis (MS) patients showed the therapy was safe and dramatically reduced patients' immune systems' reactivity to myelin by 50 to 75 percent. The therapy used billions of patients' own specially processed blood cells to create tolerance to myelin, the insulating layer that forms around nerves. In MS, the immune system attacks myelin. The approach left the normal immune system intact.

Stanford scientists create novel silicon electrodes that improve lithium-ion batteries
Stanford University scientists have dramatically improved the performance of lithium-ion batteries by creating novel electrodes made of silicon and conducting polymer hydrogel, a spongy material similar to that used in contact lenses and other household products. The scientists developed a new technique for producing low-cost, silicon-based batteries with potential applications for a wide range of electrical devices.

Even with defects, graphene is strongest material in the world
Columbia Engineering researchers demonstrate that graphene, even if stitched together from many small crystalline grains, is almost as strong as graphene in its perfect crystalline form. This resolves a contradiction between theoretical simulations, which predicted grain boundaries can be strong, and earlier experiments, which indicated they were much weaker than the perfect lattice. "We're excited to say that graphene is back and stronger than ever," says Mechanical Engineering Professor James Hone.

Scientists capture first images of molecules before and after reaction
Using atomic force microscopy, chemists for the first time can capture images of molecules before and after they react, which will allow them to better tune reactions to get the products they want. UC Berkeley chemist Felix Fischer and physicist Michael Crommie joined forces to develop the technique, which could help scientists study and improve catalytic reactions like those used widely in industry to make chemicals or crack oil.

Charred micro-bunny sculpture shows promise of new material for 3-D shaping
Researchers in Japan used state-of-the-art micro-sculpting techniques on a new type of resin that can be molded into complex, highly conductive 3-D structures (in this case the famous "Stanford bunny") with features just a few micrometers across. The team says one of the most promising applications is 3-D microelectrodes that could interface with the brain.
