Cheap, simple test detects a single virus in urine straight from the source

As Zika has reminded the world, viruses are still a major threat to a healthy populace. One of the key components to battling them is detection, but methods to do so can often be costly and complicated, which means they're not always available to the populations that most need them. Researchers at The University of Texas at Austin (UT) have joined the ranks of others seeking to make affordable virus detection more accessible to the masses by coming up with a method that uses an electrode thinner than a human cell to pick up the destructive bugs in urine.

IBM-developed macromolecule uses triple-attack technique to fight deadly viruses

Viral infections can be difficult to tackle due to their ability to rapidly develop resistance to drugs, and major viruses like Ebola and Zika pose a real threat to global health. Help might well be at hand though, with researchers from the Institute of Bioengineering and Nanotechnology in Singapore, working alongside scientists from IBM Research, developing a breakthrough macromolecule that tackles viruses in three separate ways.Read More

New low-cost Zika test looks good on paper

Researchers have developed a low-cost, paper-based method of detecting viruses like Zika and Ebola in a biological sample, and which can even identify a specific strain. The team believes the test can be used in the field to quickly and easily detect the presence of a virus, and be used to help slow the spread of future outbreaks.Read More

Portable device detects Ebola on the spot

It would definitely be an understatement to say that the sooner the Ebola virus is detected in blood samples, the better. Unfortunately, those samples currently have to be shipped off to labs for analysis, often far from the area being studied. That could soon change, though, as a compact new device can identify Ebola in under half an hour.Read More

Fighting the Zika virus with junked tires

Mosquitos like old tires. More specifically, female mosquitos like to lay their eggs in the cool, stagnant water that often accumulates within them. Now, in the fight against mosquito-borne diseases such as the Zika virus, the Government of Canada is using that fact against the insects. Researchers with the Grand Challenges Canada initiative have created a highly-effective mosquito trap, each one of which is made from a single discarded tire.Read More

Brazil starts screening transfusion blood for Zika virus

As the mosquito-borne Zira virus monopolizes the attention of Brazil's government and media, adding to the burden of the dengue epidemic, researchers are offering a method to blood banks that wish to screen transfusion blood for pregnant women and in cases of intrauterine transfusion. There is a suspicion that Zika could cause foeatuses to develop microcephaly, a condition in which babies are born with small heads and brains.Read More

Exposé of flu's cell hijacking tactics could stop viruses taking hold

It's not easy for bird flu to migrate to humans, but once there it can have wreak considerable havoc, with consequences that include death. For the first time scientists have zeroed in on the very narrow pathway that allows the passage of this type A influenza virus from birds to mammals, a discovery they say could one day enable them to shut the gate on the flu virus altogether.

New compound triggers immune response to range of RNA viruses, including Ebola and hep C

Though important advances have been made in treating RNA virus infections such as hepatitis C and influenza, a broad spectrum antiviral drug that throws a blanket over all of them, including more deadly variants like Ebola, has remained out of reach. Scientists are now reporting the discovery of a drug-like molecule that could be used to combat all RNA viruses, by triggering an innate immune response that suppresses and controls the infections.Read More

One-step urine test to simplify diagnosis of hepatitis C

According to the World Health Organization, somewhere between 130 and 150 million people around the globe suffer from chronic hepatitis C infection. As the virus is usually asymptomatic it can go undetected in its early stages, giving rise to complications such as liver damage and cirrhosis. Screening for the virus is possible, but is neither straightforward nor widely accessible, as it involves taking a blood sample and two separate lab tests. But researchers have now developed a one-step test that can detect hepatitis C using only a urine sample, promising to boost the availability of diagnosis and efforts to curb the virus around the world.Read More

Ebola vaccine shown to be 100 percent effective in field trials

Ebola is one of the most frightening viruses of modern times and the recent outbreak in West Africa sparked a worldwide effort to contain it. Though it is far from under control in much of the region, there is a glimmer of hope as the World Health Organization (WHO) has announced that in trials, a vaccine called VSV-EBOV has proven to be 100 percent effective in protecting individuals.Read More
