Blood samples stored in silk endure warmer temperatures

If they're not going to be analyzed right away, blood samples are best kept chilled as warmer temperatures can distort the biomarkers physicians rely on for diagnosis. But researchers have now discovered that they can preserve blood at higher temperatures by storing it amongst silk proteins, a development that could mean big things for health care in places where cooling facilities are scarce.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

Diagnostic blood test shows promise in early detection of Parkinson's

Early detection of Parkinson's could help doctors decide on treatment options or improve disease management. But often people get a neurological examination after symptoms appear, when vital brain cells have already been destroyed. Now a game-changing blood test is being developed to give doctors a reliable method to detect the disease earlier through clinical biomarkers.Read More

Researchers turn to tick spit to shut down our immune systems

When ticks bite humans, they inject us with a substance that keeps them disguised from our immune systems. This lets them hang on to us and feed for up to 10 days without getting attacked by our bodies' defences. While this strategy certainly serves the tick — and not the humans — very well, researchers may soon be turning the tables and employing a substance in tick saliva to help people battle damaging, and potentially deadly, autoimmune diseases.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

Low-cost bioactive paper detects blood types in under a minute

Determining a blood type to ensure compatibility ahead of a transfusion isn't straightforward at the best of times, but in regions of the world where proper medical equipment is unavailable it is nigh on impossible. A new, bioactive piece of paper promises to change that, however, with the ability to analyze just a few drops of blood and identify somebody's blood group in as little as one minute.Read More

Oscillating electric field used to remove nanoparticles from blood

Nanoparticles as a vehicle for delivering drugs precisely where they are needed promise to be a major revolution in medical science. Unfortunately, retrieving those particles from the body for detailed study is a long and involved process. But that may soon change with a team of engineers at the University of California, San Diego developing a technique that uses an oscillating electric field to separate nanoparticles from blood plasma in a way that may one day make it a routine procedure.

RNA blood test detects, classifies and pinpoints location of cancer

In an effort to find an accurate and easy method of detecting and locating cancers, negating the need for invasive cell tissue sampling, researchers from Umeå University in Sweden have developed a new blood test that looks at blood platelets in just a single drop of blood to identify cancer. Results of the method are very promising, with a 96 percent identification accuracy.
