Genomic signature could lead to new early-detection cancer test

Detecting cancer when it's still in the early stages of development is a difficult task, but an extremely important one, with the chances of effective treatment being much higher the quicker it's caught. Now, a team of researchers from the National Institute of Health (NIH) has identified a signature of tumor DNA that occurs, and is detectable, in five different cancers – a discovery that could lead to a simple early detection blood test.

Improved DNA tech could replace antibodies in detecting and treating diseases

A team of researchers from the Institute of Bioengineering and Nanotechnology at the Agency for Science, Technology and Research (A*STAR) has worked to develop an efficient technology that uses DNA to detect and treat infectious diseases. Improving upon an existing method, the research makes use of single-stranded DNA molecules called aptamers, and it could be used to treat cancer.

Inkjet printers could produce paper sensors that identify dangerous food and water contaminants

Sensors that identify infectious disease and food contaminants may soon be printed on paper using ordinary office inkjet printers. Researchers at McMaster University have developed a prototype that could lead to a commercial product in the next few years which helps doctors and scientists in the field quickly detect certain types of cancer or bacterial and respiratory infections or monitor toxin levels in water.

DNAtrax tracks tainted food with molecular bar code

According to the US Center for Disease Control (CDC), 129,000 Americans are sent to hospital and 3,000 die each year from food poisoning. Currently, tracing contaminated food is largely a matter of record keeping and detective work, but Lawrence Livermore National Laboratory (LLNL) researchers, in partnership with DNATrek, have developed DNATrax, a DNA-based additive for directly tracking food from producer to consumer.
