 Nano LettersNew fuel cell keeps going after the hydrogen runs out Materials scientists at Harvard have demonstrated a solid-oxide fuel cell (SOFC) that converts hydrogen into electricity but can also store electrochemical energy like a battery. This fuel cell can continue to produce power for a short time after its fuel has run out.

Hark! Group demonstrates first heralded single photon source made from silicon In an important step towards more practical quantum information processing, NIST researchers joined with two universities to build the first heralded single photon source made from silicon. This source complements two other recently developed silicon-based technologies needed to build a quantum optical circuit or a secure quantum communication system. Contact: Mark Esser

ACS Macro LettersNovel clay-based coating may point the way to new generation of green flame retardants In searching for better flame retardants for home furnishings -- the largest source of fuel in house fires -- NIST researchers defied the conventional wisdom and literally hit a wall, one made of clay. That turns out to be a good thing. Contact: Mark Bello

Journal of NeuroscienceProbing the roots of depression by tracking serotonin regulation at a new level An interdisciplinary team of scientists have successfully tagged a protein that regulates the neurotransmitter serotonin with tiny fluorescent beads, allowing them to track the movements of individual molecules for the first time. This capability makes it possible to study the manner in which serotonin regulates mood, appetite and sleep at a new level of detail.

Nature PhotonicsFirst 3-D nanoscale optical cavities from metamaterials Berkeley Lab researchers have created the world's smallest three-dimensional optical cavities with the potential to generate the world's most intense nanolaser beams. In addition to nanolasers, these unique optical cavities should be applicable to a broad range of other technologies, including LEDs, optical sensing, nonlinear optics, quantum optics and photonic integrated circuits.

Cell TransplantationMagnet helps target transplanted iron-loaded cells to key areas of heart Using heart-damaged rat models, researchers in France used a magnet to manipulate and guide endothelial progenitor cells loaded with iron oxide to key sites in the heart to enhance the cells' myocardial retention. The technique was aimed at optimizing stem cell delivery to areas of the heart following myocardial infarction. Previous methods have been hampered by insufficient homing to the damaged sites. The assessment of successful magnet-assisted homing was made by MRI.

Molecular Systems BiologyGlucose deprivation activates feedback loop that kills cancer cells, UCLA study shows UCLA researchers demonstrate the power of systems biology to uncover relationships between metabolism and signaling at the network level. The findings add to the emerging concept of systems integration between oncogenic signaling networks and metabolism of malignant tumors. The work lays a foundation for future studies delineating how signaling and metabolism are linked, with the ultimate goal of refining therapeutic strategies targeting cancer metabolism.

ACS NanoUCLA-led research team develops world's most powerful nanoscale microwave oscillators A team of UCLA researchers has developed the world's most powerful nanoscale microwave oscillators. The new electron spin-based oscillators came out of research at UCLA Engineering, focuses on spin-transfer torque magnetoresistive random access memory or STT-RAM, which has great potential over other types of memory currently in use for both speed and power efficiency. The new oscillators could lead to mobile communication devices that are less expensive to manufacture and deliver a much better signal quality. Contact: Matthew Chin

Nano LettersNano-sandwich technique slims down solar cells, improves efficiency Researchers from North Carolina State University have found a way to create much slimmer thin-film solar cells without sacrificing the cells' ability to absorb solar energy. Making the cells thinner should significantly decrease manufacturing costs for the technology.

Now researchers at the Niels Bohr Institute at the University of Copenhagen have studied a material that is simultaneously magnetically and electrically polarizable. This opens up new possibilities, for example, for sensors in technology of the future. The results have been published in the scientific journal, Nature Materials. Contact: Gertie Skaarup

SciencePenn researchers' study of phase change materials could lead to better computer memory Memory devices for computers require a large collection of components that can switch between two states, which represent the ones and zeros of binary language. Engineers hope to make next-generation chips with materials that distinguish between these states by physically rearranging their atoms into different phases. Researchers at the University of Pennsylvania have now provided new insight into how this phase change happens, which could help engineers make memory storage devices faster and more efficient.
