The Wi-Fi virus could reportedly spread as quickly as an airborne biological virus (Image:...

We all know to look out for viruses that can be spread over the internet, or by sharing files between computers. Now, however, scientists at the University of Liverpool have shown for the first time that special viruses could move between wireless access points using existing Wi-Fi networks – as efficiently as the common cold virus spreads between people through the air.  Read More

The current functioning prototype of the Odoreader

A new, non-invasive type of test could spell the beginning of a new age in bladder cancer diagnosis. Researchers at the University of Liverpool and University of the West of England in Bristol have created a device that can analyze the odors in urine to catch early signs of this type of cancer. The researchers claim the device has generated an accuracy rate of 100 percent in tests with 98 urine samples.  Read More

Dry water has been found to have several potential environmentally-friendly uses

You know, I’m pretty sure I remember a Far Side cartoon or something, where someone was selling powdered water – “Just add water!” Well, dry water isn’t quite the same thing. It’s 95 percent liquid water, but that water takes the form of tiny droplets each encased in a tiny globe of silica. The resultant substance is dry and granular. It first came to light in 1968, and was used in cosmetics. More recently, a University of Liverpool research team has been looking into other potential uses for the substance. They have found several, but most interesting is its ability to store gases such as carbon dioxide.  Read More

The 1906 San Fransisco earthquake killed over 3,000. A new technology could help shield bu...

According to the U.S. Geological Survey, there are 500,000 detectable earthquakes every year, of which 100,000 will be felt and about 100 will cause damage. Engineers now use seismic vibration control technology - and base isolation in particular – to make buildings more earthquake-proof. But what about existing structures? Researchers from the University of Liverpool have now developed a means of effectively making buildings “invisible” to the destructive path of a quake.  Read More

Cloud seeding in action

Rainmaking has advanced since the days when a ritual dance was believed to invoke the wet stuff, but while modern day cloud seeding has been shown to change the structure and size of clouds, it’s still debatable whether the practice actually has any effect on rainfall. After all, even if precipitation does occur after cloud seeding there’s no way of knowing whether it would have rained anyway. This uncertainty hasn’t stopped widespread use of cloud seeding in countries around the world including the US, Russia, Australia and China, which boasts the largest cloud seeding system in the world. Now a breakthrough by an international team of scientists could help in the development of new materials which could be used to enhance the process.  Read More

Scientists move a step closer to being able to make objects invisible

May 4, 2007 A computer model designed by a mathematician at the University of Liverpool has shown that it is possible to make objects, such as aeroplanes and submarines, appear invisible at close range. Scientists have already created an ‘invisibility cloak’ made out of ‘metamaterial’ which can bend electromagnetic radiation – such as visible light, radar or microwaves – around a spherical space, making an object within this region appear invisible. Until now, scientists could only make objects appear invisible from far away. Liverpool mathematician Dr Sebastien Guenneau, together with Dr Frederic Zolla and Professors Andre Nicolet from the University of Marseille, have proven - using a computer model called GETDP - that objects can also be made to appear invisible from close range when light travels in waves rather than beams. Scientists predict that metamaterials could be of use in military technology, such as in the construction of fighter jets and submarines, but it will be some years before invisibility cloaks can be developed for human beings.  Read More
