'Cowcatcher' enzyme fixes single-strand DNA

Every time one of your cells divides, it exposes its most essential component to great danger: its genome, the sum total of all its genetic information, embodied in the double-stranded helix of DNA. Prior to cell division, ...

For perfect nano-crystals, just add water

A simplified technique to fabricate nano-crystals of cerium dioxide (CeO2), which have wide-ranging technological and industrial applications, has been "unexpectedly" demonstrated by a UNSW chemist.

'Chemometer' offers easy way to test for dangerous pollutants

Imagine being able to test air or water for the presence of toxic metals – and many other potentially dangerous pollutants – with a device as easy to use as a home pregnancy kit, and with on-the-spot results as simple ...

Antifreeze, cheap materials may lead to low-cost solar energy

A process combining some comparatively cheap materials and the same antifreeze that keeps an automobile radiator from freezing in cold weather may be the key to making solar cells that cost less and avoid toxic compounds, ...

Discovery could lead to new way of cleaning up oil spills

(Phys.org) —University of Alberta mechanical engineering researchers have shown that a simple glass surface can be made to repel oil underwater. This has huge implications for development of a chemical repellent technology ...

Flexible polymer opals

A synthetic material which mimics the brightest and most vivid colours in nature, and changes colour when twisted or stretched, has been developed by researchers at the University of Cambridge, and could have important ...

Chemists find new compounds to curb staph infection

(Phys.org) —In an age when microbial pathogens are growing increasingly resistant to the conventional antibiotics used to tamp down infection, a team of Wisconsin scientists has synthesized a potent new class of compounds ...
