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.

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.

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
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
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
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
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.

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
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
The FDA (US Food and Drug Administration) has approved a new treatment for patients as an alternative to chemotherapy. The promising new non-invasive treatment by Novocure uses "Tumor Treating Fields" (NovoTTF) to treat cancerous growths and is now available for adult patients with recurring brain tumors (recurrent glioblastoma or GBM). The treatment delivers electric fields to a patient utilizing a portable, wearable device that permits the patient to maintain normal daily activities without down time. Read More
