DNA-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.

Scientists 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.

Nature: 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.

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.

Study 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.

NIST demonstrates significant improvement in the performance of solar-powered hydrogen generation
Using a powerful combination of microanalytic techniques that simultaneously image photoelectric current and chemical reaction rates across a surface on a micrometer scale, NIST researchers have shed new light on what may become a cost-effective way to generate hydrogen gas directly from water and sunlight.

Squishy hydrogels may be the ticket for studying biological effects of nanoparticles
A class of water-loving, jelly-like materials with uses ranges ranging from the mundane, such as superabsorbent diaper liners, to the sophisticated, such as soft contact lenses, could be tapped for a new line of serious work: testing the biological effects of nanoparticles, according to NIST scientists.

Friction 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.

First direct proof of Hofstadter butterfly fractal observed in moiré superlattices
A team of researchers from Columbia University, City University of New York, the University of Central Florida, and Tohoku University and the National Institute for Materials Science in Japan, have directly observed a rare quantum effect that produces a repeating butterfly-shaped energy spectrum, confirming the longstanding prediction of this quantum fractal energy structure called Hofstadter's butterfly. The study, which focused on moiré-patterned graphene, is published in Nature.

UC 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.

Pitt 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.

Making 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.

Flawed diamonds promise sensory perfection
By extending the coherence time of electron states to over half a second, a team of scientists from Lawrence Berkeley National Laboratory, the University of California at Berkeley, and Harvard University has improved the performance of one of the most potent sensors of magnetic fields on the nanoscale -- a diamond defect no bigger than a pair of atoms called a nitrogen vacancy center. The achievement is important news for nanoscale sensors and quantum computing.
