 ScienceResearchers reveal 3-D structure of bullet-shaped virus with potential to fight cancer, HIV A recent UCLA study demonstrates that with advanced imaging technique, the vesicular stomatitis virus can be modified to serve as an anti-cancer agent because it displays high selectivity in killing cancer cells while sparing normal cells. It can also be engineered as a potent vaccine against HIV/AIDS.

Physical Review LettersNIST's second 'quantum logic clock' based on aluminum ion is now world's most precise clock Physicists at the National Institute of Standards and Technology have built an enhanced version of an experimental atomic clock based on a single aluminum atom that is now the world's most precise clock, more than twice as precise as the previous pacesetter based on a mercury atom. The new aluminum clock would neither gain nor lose one second in about 3.7 billion years, according to measurements to be reported in Physical Review Letters.

Proceedings of the National Academy of SciencesGrowing cartilage -- no easy task Northwestern University researchers are the first to design a bioactive nanomaterial that promotes the growth of new cartilage in vivo and without the use of expensive growth factors. The therapy is minimally invasive, utilizes bone marrow stem cells and produces natural cartilage. Unlike bone, cartilage does not grow back, and it cannot effectively be replaced. Countless people learn this all too well when they bring their bad knees, shoulders and elbows to an orthopedic surgeon.

Lab on a ChipAdvances in cancer detection research by Virginia Tech engineer featured in British magazine An assistant professor of biomedical engineering at Virginia Tech helped engineer microsystems for the detection of water-borne pathogens using a technique called dielectrophoresis, which separates and identifies cells and microparticles suspended in a medium based on their size and electrical properties. Now he and colleagues have found a way to provide "the nonuniform electric field required for DEP that does not require electrodes to contact the sample fluid." Contact: Lynn A. Nystrom

ScienceUsing magnetic toys as inspiration, researchers tease out structures of self-assembled clusters In the Jan. 29 issue of Science, a team from Harvard led by Vinothan Manoharan and Michael Brenner, presents additional clues to how and why groups of atoms and molecules may favor less symmetrical and more complex, flexible geometric patterns. The answer relates to a familiar concept in physics -- entropy. The researchers literally first caught sight of the link by using magnetic "stick and ball" construction toys.

Physical Review LettersMismatched alloys are a good match for thermoelectrics Using the supercomputers at NERSC, Berkeley Lab researchers demonstrated that the semiconductors known as highly mismatched alloys hold great promise for the future development of high performance thermoelectric devices. Thermoelectrics could play a key role in green energy production because of their ability to convert heat into electricity.

Journal of Gene MedicineResearchers develop new tool for gene delivery Researchers have developed a new tool to deliver DNA in gene therapy. DNA delivered to the retina with a peptide called PEG-POD was expressed 215 times more efficiently than delivery of DNA alone. The finding highlights PEG-POD as a tool for nonviral gene therapy treatments for eye disorders such as age-related macular degeneration and retinitis pigmentosa.

ScienceSurprising discovery: X-rays drive formation of new crystals X-rays can do a lot of useful things but who knew they could cause crystals to form? Northwestern University researchers have discovered that X-rays can trigger the formation of a new type of crystal: charged cylindrical filaments ordered like a bundle of pencils experiencing repulsive forces, which is unknown in crystals. The results open the door to using X-rays to control the structure of materials or to develop novel biomedical therapies.

Journal of Cell BiologyNeuron connections seen in 3-D A team of researchers from the Max Planck Institute of Biochemistry, in Germany, led by the Spanish physicist Rubén Fernández-Busnadiego, has managed to obtain 3-D images of the vesicles and filaments involved in communication between neurons. The method is based on a novel technique in electron microscopy, which cools cells so quickly that their biological structures can be frozen while fully active. Contact: SINC

ScienceWatching crystals grow provides clues to making smoother, defect-free thin films To make thin films for semiconductors in electronic devices, layers of atoms must be grown in neat, crystalline sheets. But while some materials grow smooth crystals, others tend to develop bumps and defects -- a serious problem for thin-film manufacturing. Cornell physicists shed new light on how atoms arrange themselves into thin films.

Chemistry of MaterialsHarnessing the divas of the nanoworld Boron nitride nanotubes have been notoriously difficult to grow, requiring special instrumentation, dangerous chemistry, or temperatures of over 1,500 degrees Celsius to assemble. As it turns out, they just needed a little encouragement. Now, Michigan Tech physicist Yoke Khin Yap has created virtual Persian carpets of the tiny fibers on substrates made from simple catalysts.
