Researchers at the Salk Institute have discovered an on/off switch for telomerase, an enzyme that rebuilds a cellular timekeeper known as a telomere. The scientists believe that the discovery could provide a way to get human cells to divide indefinitely without degenerating, thereby regenerating healthy organs even in old age.  Read More

A new gene editing technique shows promise for the treatment of Duchenne muscular dystroph...

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

 Researchers at the University of Bradford claim to have devised a '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.  Read More

The living replica of Vincent Van Gogh's ear, grown using genetic material from one of his...

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

US researchers have engineered a bacterium whose genetic material includes DNA or bases  n...

Scientists at the Scripps Research Institute (TSRI) in California have produced a living bacterium that has a strand of artificial DNA made with chemical “letters” not found in nature or any other organism.  Read More

Using GPS (but not that  GPS), scientists can trace the geographic origins of someone's DN...

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.  Read More

The team constructed a lipid-coated nanodevice that survived the mouse immune system due t...

Researchers from Harvard University's Wyss Institute for Biologically Inspired Engineering have developed a cloaked DNA nanodevice capable of evading the body's immune defenses. The design was inspired by real world viruses and could be used to diagnose cancer and better target treatments to specific areas of tissue.  Read More

Olive oil counterfeiters may be thwarted by DNA particles, that are mixed into the liquid ...

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

It may someday be possible to ascertain someone's appearance by analyzing their DNA

As any fan of just about any TV cop show will tell you, it's possible to determine someone's sex and race based on a sample of their DNA. In the future, however, such samples may provide police with even more valuable information ... they might allow investigators to construct an image of the person's face.  Read More

The 3D model of the G-quadruplex, a four-stranded DNA sequence, that is already in use as ...

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.  Read More
