Flat bacteria in nanoslits

It appears that bacteria can squeeze through practically anything. In extremely small nanoslits they take on a completely new flat shape. Even in this squashed form they continue to grow and divide at normal speeds.

Researcher says microchannels could advance tissue engineering methods

Utilizing fractal patterns similar to those created by lightning strikes, Victor Ugaz, associate professor in the Artie McFerrin Department of Chemical Engineering at Texas A+M University, has created a network of microchannels that could advance the field of tissue engineering by serving as a three-dimensional vasculature for the support of larger tissue constructs, such as human organs.

Carbon nanocapsules for drug and energy storage

Two nanoscale devices recently reported by University of Pittsburgh researchers in two separate journals harness the potential of carbon nanomaterials to enhance technologies for drug or imaging agent delivery and energy storage systems, in one case, and, in the other, bolster the sensitivity of oxygen sensors essential in confined settings, from mines to spacecrafts.

Decorated carbon nanotubes with unique oxygen sensitivity

U.S. researchers have created tiny oxygen-sensing devices made from carbon nanotubes. They say the devices demonstrate the potential application of nanotechnology in low power, wearable gas sensors and could benefit those working in confined spaces where monitoring of oxygen concentrations is essential for survival.

Study outlines theoretical basis for new cloaking method

University of Utah mathematicians developed a new cloaking method, and it's unlikely to lead to invisibility cloaks like those used by Harry Potter or Romulan spaceships in Star Trek. Instead, the new method someday might shield submarines from sonar, planes from radar, buildings from earthquakes, and oil rigs and coastal structures from tsunamis.
