Urine-powered battery offers cheap energy source

When most people think of bacteria and urine together, chances are good they think of a not-so-pleasant infection. For researchers at the University of Bath however, putting these two thoughts together led to the development of a battery that could harness "pee power" to bring energy to parts of the world that might not otherwise have access to it.Read More

Acoustic Zoom could save dolphins' hearing while aiding geologists

If you've ever been asleep on a yacht in harbor when a submarine tests its sonar, you know that underwater sound is anything but trivial – one ping can send you out of your bunk and across the room. Small wonder that the major navies spend a fortune studying the impact of naval and civilian sonar systems on sea animals such as whales and dolphins, who live in a world of sound. Scientists at the University of Bath have developed a more cetacean-friendly sonar system called Acoustic Zoom that is not only less disruptive to marine life, but also improves resolution beyond that of current methods.Read More

Toxic shock syndrome can't hide from fluorescent medical dressing

Serious burns can lead to infection and potentially fatal toxic shock syndrome (TSS). Once an infection sets in, it is vital to begin treatment quickly to avoid or minimize a transition to TSS. The problem is, removing dressings to check for infection can be painful, slow the healing process and increase the chance of scarring. A prototype dressing developed by chemists at the University of Bath in the UK alerts doctors to the first signs of infection by glowing under ultraviolet (UV) light. Read More

Students set sights on human-powered submarine speed record

Students at the University of Warwick have announced their intention to build a human-powered submarine to compete at that highlight of the human-powered submarine events calendar, the European International Submarine Races in 2014. The team of engineering students hopes that their vessel, already named HPS Shakespeare, will beat the current speed record for a single-seat human-powered sub.Read More

Vector-based video could mean no more pixels

Unlike traditional bitmap graphics, which are made up of an array of pixels, vector graphics consist of lines, curves and shapes that are based on geometric formulas. Not only do they take up far less memory than bitmaps, but sections of them can also be enlarged without any loss of resolution. Currently, however, vector graphics aren’t well-suited to photorealistic applications, such as video. That may be about to change, though, as researchers from the UK’s University of Bath have developed a new program that is said to overcome such limitations – the scientists believe that the technology could make pixels obsolete within five years.Read More
