A new ultra-sensitive test developed by scientists from the Imperial College London and Spain’s University of Vigo has the potential to detect the earliest stages of a disease, thereby giving any treatment the best possible chance of succeeding. The researchers claim their new biosensor test is capable of detecting biomarkers (molecules which indicate the presence of a disease) at concentration levels much lower than is possible with existing biosensors. While the new test has already proven capable of detecting a biomarker associated with prostate cancer, the team says their biosensor could be easily reconfigured to detect biomarkers related to other diseases or viruses.  Read More

One of the biggest problems in fighting the spread of AIDS has always been convincing people to have themselves tested regularly. Unfortunately, getting someone to take a trip to a clinic isn't always easy, particularly in areas where there aren't many options for discreet testing. In a development that could leap right over this privacy hurdle, the U.S. Food and Drug Administration has just unanimously approved an over-the-counter HIV test that enables people to test themselves in their own home and receive results in just 20 minutes.  Read More

The thumb-sized Domino chip can perform 20 genetic tests from a drop of blood

A genetic testing mini-lab developed by researchers at the University of Alberta to set to begin commercial trials within a year. The Domino system provides a portable, cheap and powerful alternative to conventional laboratories that delivers a range of point-of-care diagnostic possibilities including tests for blood borne diseases such as malaria and those affecting farm animals.  Read More

Anitbiotic-resistant bacteria have been discovered in the Carlsbad Caverns National Park (...

Research into the growing emergence of drug-resistant bacteria, could be greatly assisted by the discovery of bacteria from deep within Lechuguilla Cave in New Mexico. The previously unknown strains of bacteria, which have never before been exposed to humans, were found to possess a naturally occurring resistance to multiple types of antibiotics that doctors currently use to treat patients. This means that new forms of bacteria may have been exposed to undiscovered antibiotics which, in turn could be used against currently untreatable infections in the future.  Read More

Assistant professor Kee-Hong Kim from Purdue University is testing a compound that is comm...

Researchers from Purdue University in Indiana are testing a compound found in red wine that has the ability to block the processes of fat cell development. The research into the compound known as piceatannol may lead towards finding a simple method to combat obesity.  Read More

The simple, inexpensive, folded-paper-based oPAD could detect diseases in body fluid sampl...

In First World countries' medical systems, the standard way of checking a patient's body fluid samples is to send them off to a lab. In developing nations, however, such labs often don't exist, nor does the infrastructure for transporting biological samples. Fortunately, a number of groups have been developing simple, inexpensive testing devices that could be used by clinicians in these countries. One of the latest gadgets is the very simple origami Paper Analytical Device, or oPAD – it's made out of paper, could be purchased for under 10 cents, and is folded together by the user.  Read More

University of Tennessee researchers have invented a device that instantly detects diseases...

Infectious diseases these days seem to have gotten a lot of attention, with media hype and threats of pandemics often being portrayed in apocalyptic sci-fi movies. We all know that several types of these diseases can spread rapidly, and it is crucial that doctors be able to identify them quickly in order to prevent an epidemic. Unfortunately, current testing methods can take hours and even days, delaying the process of adequate prevention. It should then ease your mind to hear that researchers at the University of Tennessee have invented a device that can rapidly detect these unwanted afflictions.  Read More

Maintaining sugar levels in a brain protein known as tau could slow or prevent Alzheimer's...

We’ve reported on numerous different approaches by scientists looking to tackle Alzheimer’s disease. While some, such as the anticancer drug bexarotene and a compound known as J147, show great promise, there is still no approved treatment to slow the disease’s progression. The latest promising candidate for a treatment comes from Canada’s Simon Fraser University (SFU), where a team has concluded that ensuring that sugar levels in a brain protein known as tau are maintained could slow or prevent the fatal disease.  Read More

Electron micrographs of hepatitis C virus purified from cell culture

Although the existence of hepatitis C had been postulated in the 1970s, it wasn’t until 1989 that a team led by Michael Houghton identified the virus. Often being asymptomatic, it is estimated between 130 – 170 million people worldwide are infected with the virus that can lead to scarring of the liver and cirrhosis. Although treatment with medication is available, it isn’t effective in all cases and between 20 to 30 percent of those infected with hepatitis C develop some form of liver disease. Now Houghton and a team at the University of Alberta have developed a vaccine from a single strain that is effective against all known strains of the disease.  Read More

The programmable DNA nanorobot developed by Wyss Institute researchers is shaped like a ba...

We've seen various experimental approaches that aim to increase the efficacy of chemotherapy while also reducing its damaging side effects by specifically targeting cancer cells. The latest encouraging development comes from Harvard's Wyss Institute for Biologically Inspired Engineering where researchers have created a barrel-like robotic device made from DNA that could carry molecular instructions into specific cells and tell them to self-destruct. Because the DNA-based device could be programmed to target a variety of cells, it could be used to treat a range of diseases in addition to providing hope in the fight against cancer.  Read More
