Graphene flakes to calm synapses
Innovative graphene technology to buffer the activity of synapses-- this is the idea behind a recently-published study in the journal ACS Nano coordinated by the International School for Advanced Studies in Trieste and the University of Trieste. In particular, the study showed how effective graphene oxide flakes are at interfering with excitatory synapses, an effect that could prove useful in new treatments for diseases like epilepsy

Enhancing lab-on-a-chip peristalsis with electro-osmosis
Researchers at the Indian Institute of Technology's Advanced Technology Development Center in Kharagpur, West Bengal have conducted lubrication theory-based analyses to explore the hydrodynamic effects of improving flow rate in pre-existing peristaltic hardware relying on an external electric field. Their research, which assesses the combined effects of electric fields and peristalsis on the channel flow rate, appears this week in Physics of Fluids, from AIP Publishing.

Performing cellular surgery with a laser-powered nanoblade
To study certain aspects of cells, researchers need the ability to take the innards out, manipulate them, and put them back. Options for this kind of work are limited, but researchers reporting May 10 in Cell Metabolism describe a 'nanoblade' that can slice through a cell's membrane to insert mitochondria. The researchers have previously used this technology to transfer other materials between cells and hope to commercialize the nanoblade for wider use in bioengineering.

Common nanoparticle has subtle effects on oxidative stress genes
A nanoparticle commonly used in food, cosmetics, sunscreen and other products can have subtle effects on the activity of genes expressing enzymes that address oxidative stress inside two types of cells. While the titanium dioxide nanoparticles are considered non-toxic because they don't kill cells at low concentrations, these cellular effects could add to concerns about long-term exposure to the nanomaterial.

Novel functionalized nanomaterials for CO2 capture
Climate change due to excessive CO2 levels is one of the most serious problems mankind has ever faced. CO2 emissions need to be reduced urgently to avoid potentially dangerous and irreversible effects of climate change. To mitigate such emissions, CO2 capture is one of the best solutions. Scientists at the Tata Institute of Fundamental Research, Mumbai, have developed novel functionalized nanomaterials that can capture CO2 with superior capture capacity and stability over conventional sorbents.

Speedy ion conduction in solid electrolytes clears road for advanced energy devices
A team led by the Department of Energy's Oak Ridge National Laboratory used state-of-the-art microscopy to identify a previously undetected feature, about 5 billionths of a meter (nanometers) wide, in a solid electrolyte. The work experimentally verifies the importance of that feature to fast ion transport, and corroborates the observations with theory. The new mechanism the researchers report in Advanced Energy Materials points out a new strategy for the design of highly conductive solid electrolytes.

A compact, efficient single photon source that operates at ambient temperatures on a chip
Hebrew University of Jerusalem scientists demonstrated a compact, efficient single photon source that can operate on a chip at ambient temperatures. A highly directional single photon source could lead to compact, cheap, and efficient sources of quantum information bits for future quantum technological applications. The team is working on a new generation of devices to allow production of single photons straight from the chip into optical fibers, without any additional optical components.

An experiment seeks to make quantum physics visible to the naked eye
Predictions from quantum physics have been confirmed by countless experiments, but no one has yet detected the quantum physical effect of entanglement directly with the naked eye. This should now be possible thanks to an experiment proposed by a team around a theoretical physicist at the University of Basel. The experiment might pave the way for new applications in quantum physics.

Nuclear pores captured on film
Using an ultra fast-scanning atomic force microscope, a team of researchers from the University of Basel has filmed 'living' nuclear pore complexes at work for the first time. Nuclear pores are molecular machines that control the traffic entering or exiting the cell nucleus. In their article published in Nature Nanotechnology, the researchers explain how the passage of unwanted molecules is prevented by rapidly moving molecular 'tentacles' inside the pore.
