Natural clay found to kill deadly bacteria

A global effort is under way to find effective treatments for deadly hospital-acquired infections, with many such dangerous bacteria proving worryingly resistant to antibiotics. Now, help may have been found in the most unlikely of places, with researchers finding positive results when studying an old folk remedy – natural Canadian clay.Read More

Improved DNA tech could replace antibodies in detecting and treating diseases

A team of researchers from the Institute of Bioengineering and Nanotechnology at the Agency for Science, Technology and Research (A*STAR) has worked to develop an efficient technology that uses DNA to detect and treat infectious diseases. Improving upon an existing method, the research makes use of single-stranded DNA molecules called aptamers, and it could be used to treat cancer.Read More

Light-activated quantum dots successfully combat drug-resistant bacteria

Antibiotic-resistant bacteria are an increasingly big problem for global health. They kill in excess of 23,000 people in the US every year, with their ability to rapidly develop an immunity to antibiotic treatments making them extremely difficult to eradicate. Now, new research being conducted at the University of Colorado Boulder has found that tiny light-activated particles known as quantum dots might be useful in tackling the infections.Read More

Row-bot cleans dirty water and powers itself by eating microbes

Inspired by the water boatman bug, a team at the University of Bristol has created the Row-bot, a robot prototype that is designed to punt itself across the top of the water in dirty ponds or lakes, and "eat" the microbes it scoops up. It then breaks these down in its artificial stomach to create energy to power itself. In this way, it generates enough power to continuously impel itself about to seek out more bacteria to feed upon.Read More
