Microbubbles and ultrasound open the blood-brain barrier to administer drugs
The impassable blood-brain barrier prevents microorganisms from entering our brain, however it also blocks medicines that could help treat Parkinson's, Alzheimer's and other neurodegenerative diseases. Now, a Spanish physicist and other researchers at the University of Columbia (USA) have succeeded in embedding these substances in tiny lipid bubbles, in such a way that ultrasound can be used to release them into the specific area of the brain where they are needed.

Quantum obstacle course changes material from superconductor to insulator
Researchers from Brown University have shown a way to break superconductivity by disrupting the coherence of superconducting Cooper pairs. Such a phase change from superconducting to insulating had been predicted by theory, but hadn't been demonstrated experimentally. The research could help scientists better understand how defects can affect the quantum behavior of materials.

A method for storing vaccines at room temperature
Several simple and inexpensive techniques make it possible to store antiviral-vaccines at room temperature for several months. This discovery by EPFL researchers and partners could make a difference in inaccessible areas and developing countries where maintaining cold-chain transportation of vaccines is complicated and expensive.

Nanotechnology a 'green' approach to treating liver cancer
According to the American Cancer Society, more than 700,000 new cases of liver cancer are diagnosed worldwide each year. Currently, the only cure for the disease is to surgically remove the cancerous part of the liver or transplant the entire organ. However, an international study led by University of Missouri School of Medicine researchers has proven that a new minimally invasive approach targets and destroys precancerous tumor cells in the livers of mice and in vitro human cells.

A new technique for structural color, inspired by birds
Structural coloration has long interested researchers and engineers because of its durability and potential for application in solar arrays, biomimetic tissues and adaptive camouflage. But today's techniques to integrate structural color into materials are time-consuming and costly. Now, researchers have developed a new, more robust and cost effective system to build large-scale metamaterials with structural color.

'Diamond-age' of power generation as nuclear batteries developed
New technology has been developed that uses nuclear waste to generate electricity in a nuclear-powered battery. A team of physicists and chemists from the University of Bristol have grown a man-made diamond that, when placed in a radioactive field, is able to generate a small electrical current. The development could solve some of the problems of nuclear waste, clean electricity generation and battery life.

Physicists spell 'AV' by manipulating Abrikosov vortices
A nanophotonics group lead by Prof. Brahim Lounis of the University of Bordeaux and including scientists from MIPT has performed a unique experiment involving the optical manipulation of individual Abrikosov vortices in a superconductor. The manipulation technique proposed in the study could be used to develop optically controlled RSFQ logic elements. This technology is seen as the most promising in terms of the design of superfast memory for quantum computers.

Micro-bubbles make big impact
The quest to develop wireless micro-robots for biomedical applications requires a small-scale 'motor' that can be wirelessly powered through biological media. While magnetic fields can be used to power small robots wirelessly, they don't provide selectivity since all actuators under the same magnetic field just follow the same motion. To address this limitation of magnetic actuation, researchers have developed a way to use microbubbles to provide the specificity needed to power micro-robots for biomedical applications.

From champagne bubbles, dance parties and disease to new nanomaterials
Nucleation processes are a first step in the structural rearrangement involved in the phase transition of matter. Understanding this process is critical for preventing, halting or treating cases of nucleation processes gone wrong -- such as in human disease. Now, a team of researchers have made headway toward understanding this problem from a molecular point of view in a new study, which they discuss in this week's The Journal of Chemical Physics.
