Cancer screening with a simple "universal" blood test

By - July 28, 2014 1 Picture
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.

Artist creates a living copy of Vincent Van Gogh's ear with relative's DNA

By - July 11, 2014 2 Pictures
If you thought cloning mice, frogs and extinct mammoths to be challenging, how about cloning Vincent Van Gogh's ear? Dutch artist Diemut Strebe has grown a living replica of the ear that Vincent Van Gogh reportedly sliced off in a troubled episode, using genetic material from one of Van Gogh's direct descendants. With a lifespan of 80 years or more, the ear could live as long as any one of us, says Strebe, who is investigating the idea of replicating people from historical DNA. Read More

Researchers develop DNA GPS tool to accurately trace geographical ancestry

By - May 1, 2014 2 Pictures
An international team of scientists has developed a process that allows them to pinpoint a person’s geographical origin going back 1,000 years. Known as the Geographic Population Structure (GPS) tool, the method is accurate enough to locate the village from which the subject’s ancestors came, and has significant implications for personalized medical treatment.

Added DNA could be used to authenticate premium olive oil

By - April 25, 2014 1 Picture
When most people think of counterfeit goods, they probably picture things like handbags or watches. In fact, there's also a huge market for knock-off high-end food products, such as extra-virgin olive oil. Scientists from Switzerland's ETH Zurich research group, however, have come up with a possible method of thwarting the makers of that bogus oil – just add synthetic DNA particles to the real thing. And yes, consumers would proceed to swallow those particles. Read More

3D-printed molecule provides new perspective for cancer research

By - February 12, 2014 1 Picture
While two-dimensional modeling of double-stranded DNA molecules has been useful for the purpose of cancer research, the composition of the G-quadruplex, a four-stranded DNA sequence, has proven a different beast. A 3D printing lab at the University of Alabama has successfully produced a physical model of its molecular structure, improving understanding of its makeup and potentially, helping develop a treatment for pancreatic cancer.

"Smart bomb" puts antibiotic resistant bacteria in its sights

By - January 30, 2014 1 Picture
The increasing prevalence of bacteria resistant to antibiotic drugs is largely blamed on the over prescription and use of such drugs in humans and animals, leading to the evolution of so-called "superbugs." A new antibiotic "smart bomb" that can target specific strains of bacteria could provide the next-generation antibiotic drugs needed to stave off the threat of antibiotic-resistant bacteria.
