(PhysOrg.com) -- Using cutting-edge microscopy techniques, researchers have gained insight into how human mummies can be extremely well-preserved for thousands of years. A team of scientists from Germany and Italy has investigated ...
(PhysOrg.com) -- With its unique double-helical structure, DNA has the ability to be used as a programmable building material to construct designer nanoscale architectures. Complex DNA architectures could have a variety of ...
A research group has significantly improved the quality of brain-function measurements by coating metal neural electrodes with carbon nanotubes. Their work could potentially allow scientists to learn more about brain diseases ...
A new study by researchers from the University of Waterloo in Ontario, Canada, hints that carbon nanotubes may be toxic to microorganisms. When cultures of a certain key protozoan, a single-cell organism, were exposed to ...
Tiny particles called nanobacteria have intrigued researchers in many ways since their discovery 20 years ago, but perhaps the most controversial question they pose is whether or not they are alive.
For the first time, scientists have directly imaged carbon nanotubes entering and migrating within human cells, determining as a result that whether the nanotubes cause cell death depends on the dose and exposure time. The ...
Scientists from the California Institute of Technology have fabricated a motor that runs autonomously, and is powered only by the free energy of DNA hybridization. The molecular motor was inspired by bacterial pathogens such ...
In order to investigate the processes that go on inside a single human cell—or even specific subcellular compartments—researchers need a device that is small and controlled enough to pass through the delicate cell membrane. ...
Recent research has revealed that a standard cell-viability test may be causing carbon-nanotubes to “fake” toxicity. This work may explain why some studies have concluded that carbon nanotubes – which are being studied for ...
Opening a whole new interface between nanotechnology and neuroscience, scientists at Harvard University have used slender silicon nanowires to detect, stimulate, and inhibit nerve signals along the axons and dendrites of ...
