Zika Virus Associated With New Type Of Brain Disease

By Tim Sandle

Rates of Zika virus have been increasing in many countries, with infection primarily through mosquito bites. The disease is associated with several ill-health effects. To add to those previously reported, an association with a new autoimmune disorder has been reported.   Zika virus is a member of the Flaviviridae virus family. In most people, the […]

Hundreds of Dialysis Patients Exposed to Disease

By Tim Sandle

During a routine inspection of Baystate Medical Center by the Massachusetts Department of Public Health, inspectors uncovered a worrying fact. This was that 575 dialysis patients could potentially have been exposed to pathogens.   This was because, an official report indicates, the hospital “failed to adhere to standard protocol.”   Moreover, the report indicated that […]

Five Of The Most Incredible Parasites

By Tim Sandle

Parasitism is a general term for a ‘non-mutual symbiotic relationship’ between species. Here one species – the parasite – benefits at the expense of the other (called the host). Parasites rarely kill their host; however, carrying a parasite can cause a range of unpleasant symptoms. Parasites range in size from tiny, one-celled organi (protozoa) to […]

Lighting Up Disease Carrying Mosquitoes

By Tim Sandle

A scientist has devised a simple technique for detecting genetic material from West Nile and chikungunya virus in samples, taken from mosquitoes. To help in the battle against disease carrying mosquitoes, Dr. Robert Meagher, of Sandia National Laboratories, has devised a new method for simultaneously detecting a range of mosquito-borne diseases, such as malaria. To […]

Using Bacteria To Power A Robot

By Tim Sandle

Bacteria can be used to power a micro-sized robot by propelling it in a certain direction. This is remarkable enough, but now engineers and microbiologists have managed to fully control the direction and avoid obstacles on the way. The devices in question are called “bio-robots” and they are essentially a computer chips coated with motile […]

Aim To Get Zika Out Of The Way Before Olympics

By Tim Sandle

With athletes considering pulling out, especially women, Olympics chiefs are getting nervous. The reason? The next summer Olympics is taking place in Brazil, the epicenter of the Zika virus outbreak. Zika virus disease is spread by mosquitoes, and causes a mild fever in 1 out of 4 people bitten. Although the fever dies away in a […]

Nanotech Delivery System Tackles Skin Disease

By Tim Sandle

Researchers have developed a nanotechnology system designed to induce the body’s own natural defenses to fight various types of skin diseases. This works by stimulating the body’s own cellular pathway. The skin is exposed daily to potentially harmful substances including pollutants, ultra-violet rays, and radiation. As these are absorbed into the skin they trigger free radicals called Reactive […]

New Way To Fight Deadly Pathogens

By Tim Sandle

Microbiologists, based at the University of Geneva, have discovered a new way to tackle pathogenic bacteria. This involves a toxin-antitoxin system. By studying an organism called studying the bacterium Caulobacter crescentus, they have singled out a toxin-antitoxin system of interest called HigBA. Toxin-antitoxin systems are found in most bacterial cells. Such systems encode both a […]

Zika On The Move

By Tim Sandle

There has been considerable coverage in the news recently about Zika virus, which is transmitted by mosquitoes. Unlike similar viruses with similar vectors, such as dengue, Zika is relatively under-researched. This is despite the first reported case of the virus being reported during the 1940s. One of the reasons why Zika is a prominent discussion […]

Is A Test For Blood Cancer Possible?

By Tim Sandle

Will a blood test for cancer be possible one day? Different teams of scientists hope that, at some point in the near future, examining a blood sample will reveal a range of different cancers. The development of a blood test would be type of ‘liquid biopsy’, where free-floating cancer cells or DNA fragments would be […]
