 ACS NanoPenn research makes advance in nanotech gene sequencing technique The allure of personalized medicine has made new, more efficient ways of sequencing genes a top research priority. One promising technique involves reading DNA bases using changes in electrical current as they are threaded through a nanoscopic hole. Now, a team led by University of Pennsylvania physicists has used solid-state nanopores to differentiate single-stranded DNA molecules containing sequences of a single repeating base.

Nature MaterialsKinks and curves at the nanoscale Since 2004, materials scientists and nanotechnology experts have been excited about a special of arrangement of atoms called a "coherent twin boundary" that can add enormous strength to metals like gold and copper. The CTBs are described as "perfect," appearing like a one-atom-thick plane in models and images. New research shows that these boundaries are not perfect. Even more surprising, the newly discovered kinks and defects appear to be the cause of the CTB's strength.

ACS NanoDNA-guided assembly yields novel ribbon-like nanostructures DNA "linker" strands coax nano-sized rods to line up in way unlike any other spontaneous arrangement of rod-shaped objects. The arrangement -- with the rods forming "rungs" on ladder-like ribbons could result in the fabrication of new nanostructured materials with desired properties.

NatureScientists capture first direct proof of Hofstadter butterfly effect A team of researchers from several universities – including UCF –has observed a rare quantum physics effect that produces a repeating butterfly-shaped energy spectrum in a magnetic field, confirming the longstanding prediction of the quantum fractal energy structure called Hofstadter's butterfly. This discovery by the team paves the way for engineering new types of extraordinary nanoscale materials that can be used to develop smaller, lighter and faster electronics, including sensors, cell phones, tablets and laptops.

NatureNature: X-ray tomography on a living frog embryo X-ray radiographs provide information about internal structures of organisms such as bones. Alternatively, X-rays can image soft tissues throughout early development of vertebrates. A new X-ray method was presented recently in a Nature article published by a German-American-Russian research team. Time-lapse sequences of cellular resolution were obtained of three dimensional reconstructions showing developing embryos of the clawed frog. Instead of absorption of X-rays, the method is based on their diffraction. Contact: Monika Landgraf

Nanotechnology Moth-inspired nanostructures take the color out of thin films Inspired by the structure of moth eyes, researchers at North Carolina State University have developed nanostructures that limit reflection at the interfaces where two thin films meet, suppressing the "thin-film interference" phenomenon commonly observed in nature. This can potentially improve the efficiency of thin-film solar cells and other optoelectronic devices.

NASA completes first part of Webb Telescope's 'eye surgery' operation Much like the inside of an operating room, in the clean room at NASA's Goddard Space Flight Center in Greenbelt, MD, engineers worked meticulously to implant part of the eyes of the James Webb Space Telescope. They scrubbed up and suited up to perform one of the most delicate performances of their lives. That part of the eyes, the MIRI, or Mid-Infrared Instrument, will glimpse the formation of galaxies and see deeper into the universe than ever before.

Society for Academic Emergency Medicine Annual MeetingStudy finds plasmin -- delivered through a bubble -- more effective than tPA in busting clots A new University of Cincinnati study has found that, when delivered via ultrasound, the natural enzyme plasmin is more effective at dissolving stroke-causing clots than the standard of care, recombinant tissue plasminogen activator. The novel delivery method involved trapping plasmin into bubble-like liposomes, delivering them to the clot intravenously and bursting it via ultrasound. The research team presented their abstract today at the Society for Academic Emergency Medicine annual meeting. Contact: Katy Cosse

Angewandte Chemie International EditionFriction in the nano-world Whether in vehicle transmissions, hip replacements, or tiny sensors for triggering airbags: The respective components must slide against each other with minimum friction to prevent loss of energy and material wear. Investigating the friction behavior of nanosystems, scientists from the Technische Universitaet Muenchen have discovered a previously unknown type of friction that sheds new light on some previously unexplainable phenomena.

Nature PhotonicsUC Riverside scientists discovering new uses for tiny carbon nanotubes Nanotubes are stronger than steel and smaller than any element of silicon-based electronics. They can potentially process information faster while using less energy. The challenge has been figuring out how to incorporate these properties into useful electronic devices. Now scientists at the University of California, Riverside have discovered that by adding ionic liquid -- a kind of liquid salt -- they can modify the optical transparency of single-walled carbon nanotube films in a controlled pattern.

Journal of the American Chemical SocietyPitt chemists demonstrate nanoscale alloys so bright they could have potential medical applications Alloys like bronze and steel have been transformational for centuries, yielding top-of-the-line machines necessary for industry. As scientists move toward nanotechnology, however, the focus has shifted toward creating alloys at the nanometer scale -- producing materials with properties unlike their predecessors. Now, research at the University of Pittsburgh demonstrates that nanometer-scale alloys possess the ability to emit light so bright they could have potential applications in medicine. Contact: B.

Nature CommunicationsMaking gold green: New non-toxic method for mining gold Northwestern University scientists have struck gold in the laboratory. They have discovered an inexpensive and environmentally benign method that uses simple cornstarch -- instead of cyanide -- to isolate gold from raw materials in a selective manner. This green method extracts gold from crude sources and leaves behind other metals that are often found mixed together with the crude gold.
