Research offers promising new approach to treatment of lung cancer
Researchers have developed a new drug delivery system that allows inhalation of chemotherapeutic drugs to help treat lung cancer, and in laboratory and animal tests it appears to reduce the systemic damage done to other organs while significantly improving the treatment of lung tumors -- the tumors virtually disappeared.

New technique may open up an era of atomic-scale semiconductor devices
Researchers at North Carolina State University have developed a new technique for creating high-quality semiconductor thin films at the atomic scale -- meaning the films are only one atom thick. The technique can be used to create these thin films on a large scale, sufficient to coat wafers that are two inches wide, or larger.

Whirlpools on the nanoscale could multiply magnetic memory
Research at Lawrence Berkeley National Laboratory's Advanced Light Source promises four-bit magnetic cells instead of the two-bit magnetic domains of standard magnetic memories. Magnetic vortices are whirlpools of magnetic field, in which electron spins point either clockwise or counterclockwise. In the crowded center of the whirlpool the spins point either down or up. These four orientations could represent separate bits of information in a new kind of memory, if controlled independently and simultaneously.

Researchers perform fastest measurements ever made of ion channel proteins
A team of researchers at Columbia Engineering has used miniaturized electronics to measure the activity of individual ion-channel proteins with temporal resolution as fine as one microsecond, producing the fastest recordings of single ion channels ever performed. They designed a custom integrated circuit to perform these measurements, in which an artificial cell membrane and ion channel are attached directly to the surface of the amplifier chip.

Penn 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.

Kinks 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.

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.
