New imaging method reveals nanoscale details about DNA

Researchers have developed a new enhanced DNA imaging technique that can probe the structure of individual DNA strands at the nanoscale. Since DNA is at the root of many disease processes, the technique could help scientists ...

Cheap and quick HIV testing made possible with DVD scanners

Thanks to USB sticks and video streaming, DVD players are becoming all but obsolete. But their cheap optics may find a new life in a cost-effective and speedy technique for on-the-spot HIV testing and other analytics.

Virtual nanoscopy: Like 'Google Earth' for cell biologists

Just as users of Google Earth can zoom in from space to a view of their own backyard, researchers can now navigate biological tissues from a whole embryo down to its subcellular structures thanks to recent advances in electron ...

Helium raises resolution of whole cell imaging

The ability to obtain an accurate three-dimensional image of an intact cell is critical for unraveling the mysteries of cellular structure and function. However, for many years, tiny structures buried deep inside cells have ...

Gold probes may offer valuable insight into cancer

(Phys.org) —Nanoprobes made from gold could be used to predict people's cancer risk – and the effectiveness of treatments, following research by University of Strathclyde academics.

Molecular energy machine as a movie star

Researchers at the Paul Scherrer Institute PSI have used the Swiss Light Source SLS to record a molecular energy machine in action and thus to reveal how energy production at cell membranes works. For this purpose they developed ...

Giving transplanted cells a nanotech checkup

Researchers at Johns Hopkins have devised a way to detect whether cells previously transplanted into a living animal are alive or dead, an innovation they say is likely to speed the development of cell replacement therapies ...

Researchers build most complex synthetic biology circuit yet

Using genes as interchangeable parts, synthetic biologists design cellular circuits that can perform new functions, such as sensing environmental conditions. However, the complexity that can be achieved in such circuits has ...

Nanomagnets guide stem cells to damaged tissue

Microscopic magnetic particles have been used to bring stem cells to sites of cardiovascular injury in a new method designed to increase the capacity of cells to repair damaged tissue, UCL scientists announced today.
