A new device, employing the same chemical which lights up fireflies, can easily detect food contamination; the researchers who developed the system hope it will soon be used to test for other diseases, including HIV-AIDS.

Food contamination can now be detected easily by a new device based on the chemical which lights up fireflies.

The Bioluminescent Assay in Real-Time (BART), jointly invented by Professor Jim Murray of the Cardiff University’s School of Biosciences and Dr. Laurence Tisi of Lumora, allows users to test rapidly and simply for food poisoning bacteria. Professor Murray and his partners at technology company Lumora Ltd. hope to develop the system to test for other diseases, including HIV-AIDS.

Scientists have produced a previously unseen uranium molecule in a move that could improve clean-up of nuclear waste.

The distinctive butterfly-shaped compound is similar to radioactive molecules that scientists had proposed to be key components of nuclear waste. These molecules, however, were thought too unstable to exist for long.

A University of Edinburgh release reports that researchers have shown the compound to be robust, which implies that molecules with a similar structure may be present in radioactive waste.

University of Edinburgh scientists, who carried out the study, say their findings suggest the molecule may play a role in forming clusters of radioactive material in waste.

These are difficult to separate during clean-up. Improving treatment processes for nuclear waste, including targeting this type of molecule, could help the nuclear industry move towards cleaner power generation.

Decontaminating polluted waste water costs millions, but a new discovery by scientists at the University of Brighton could result in huge savings as well as delivering safer, cleaner water

Decontaminating polluted waste water costs millions, but a new discovery by scientists at the University of Brighton could result in huge savings as well as delivering safer, cleaner water.

The research, recently published in the journal Angewandte Chemie International Edition, represents a significant shift in scientists’ understanding of chemistry. Mercury is a serious contaminant so this breakthrough could save millions of pounds.

Scientists show that by cloaking components of structures with pressurized rubber, powerful waves such as those produced by an earthquake would not “see” the building — they would simply pass around the structure and thus prevent serious damage or destruction

University of Manchester mathematicians have developed the theory for a Harry Potter-style cloaking device which could protect buildings from earthquakes.

Dr. William Parnell’s team in the University’s School of Mathematics has been working on the theory of invisibility cloaks which, until recently, have been merely the subject of science fiction.

In recent times, however, scientists have been getting close to achieving cloaking in a variety of contexts. A University of Manchester release reports that the work from the team at Manchester focuses on the theory of cloaking devices which could eventually help to protect buildings and structures from vibrations and natural disasters such as earthquakes.
