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.Read More

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.Read More

New approach could lead cancer cells down path of destruction

Scientists from Case Western Reserve University's School of Medicine have discovered a potential treatment that may steer cancer cells toward their own destruction. The study focused on a particular gene that was found to influence levels of a tumor-fighting protein called 53BP1, the heightened presence of which makes cancer cells more vulnerable to existing forms of treatment.

Swiss scientists discover DNA remains active after space journey and re-entry

It may sound like the first chapter of a Quatermass thriller, but scientists from the University of Zurich have discovered that DNA can survive not only a flight through space, but also re-entry into the Earth's atmosphere, and still remain active. The findings are based on suborbital rocket flights and could have considerable impact on questions about the origins of life on Earth and the problems of terrestrial space probes contaminating other planets.Read More

DNA test identifies venomous snakes from their bites

When a snake-bite victim shows up at a hospital, it's vitally important for caregivers to know what species of snake bit them. Without that knowledge, they won't know what sort of anti-venom – if any – is required. Making that ID could one day be much easier, thanks to a current study in which species were reliably identified via snake DNA obtained from fang marks in victims' bite wounds. Read More

Large 3D nanostructures built from Lego-like DNA bricks

The very same building blocks that make us have been successfully programmed to form 32 differently-shaped crystal structures. The structures feature a precisely-defined depth and a variety of sophisticated 3D nanoscale attributes, thereby laying further foundations for the use of DNA to revolutionize nanotechnology.Read More

New gene editing method corrects muscular dystrophy in mice

Researchers at the University of Texas (UT) Southwestern Medical Center have developed a technique that corrects a mutation leading to Duchenne muscular dystrophy (DMD). The technique, called CRISPR/Cas9-mediated genome editing, removes the mutation entirely in mice, and could have far-reaching consequences in the treatment of muscular dystrophy in people.Read More

Cancer screening with a simple "universal" blood test

Although many dread the prick of a blood test, most would find it a preferable testing method to invasive and expensive biopsies. That's why a blood test for cancer is the goal of many research efforts, including one at the University of Bradford in the UK, where researchers are claiming to have devised a simple universal blood test for the disease that relies on the fact that white blood cells in cancer patients are already damaged from battling cancerous cells.
