Nanotechnology delivers hepatitis B vaccine

Brazilian and European researchers have demonstrated exactly how a nanotechnology-based compound delivers an oral vaccine against hepatitis B to the immune system. When particles containing silica and an antigen combine, ...

New method to create ultrafast 3-D images of nanostructures

Lensless microscopy with X-rays, or coherent diffractive imaging, is a promising approach. It allows researchers to analyse complex three-dimensional structures, which frequently exist in nature, from a dynamic perspective. ...

Egyptian mummies virtually unwrapped in Australia

The hidden secrets of Egyptian mummies up to 3,000 years old have been virtually unwrapped and reconstructed for the first time using cutting-edge scanning technology in a joint British-Australian exhibition.

Mini X-ray source with laser light

Physicists from Ludwig-Maximilians-Universit√§t, the Max Planck Institute of Quantum Optics and the TU M√ľnchen have developed a method using laser-generated X-rays and phase-contrast X-ray tomography to produce three-dimensional ...

Rare tidal movements expose Kimberley dinosaur tracks

While audiences in Perth attend Walking with Dinosaurs this weekend palaeontologists working near Broome will be documenting the extinct vertebrates' extensive fossilised footsteps using laser scanning technology.

Japan firm showcases Bat-Signal of the future

A free-floating image created by firing lasers into thin air was unveiled in Japan on Monday, offering the possibility one day of projecting messages into a cloudless sky, as seen in Batman.

Global first as Witsies split pollen

Wits researchers have become the first to cut sections through pollen grains and make it possible to view a three dimensional image of the internal wall. This positions them to determine how the characteristics of the internal ...
