DNA

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

A new approach targets bad bacterai, such as Salmonella (pictured), while leaving good bac...

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.  Read More

A rendering of the nanometer-scale DNA clamp, that recognizes genetic mutations more stron...

Scientists have developed a special DNA clamp to act as a diagnostic nano machine. It's capable of detecting genetic mutations responsible for causing cancers, hemophilia, sickle cell anemia and other diseases, more efficiently than existing techniques. Not only can the clamp be used to develop more advanced screening tests, but it could also help create more efficient DNA-based nano machines for targeted drug delivery.  Read More

Scientists have created piglets that glow green under a black-light (see the video below)

Scientists in Guangdong Province, Southern China, have created piglets that glow green under a black-light. The glow is caused by a fluorescent protein from jellyfish DNA that was transferred into the embryos within the sow, as a marker to show that the transfer of genetic material had been successful.  Read More

A new test is able to genetically discriminate between 'identical' twins (Photo: Shutterst...

Although they only account for around three in every thousand deliveries, monozygotic, or "identical" twins are fertile fodder for crime writers and cop shows. This isn't surprising considering that DNA fingerprint testing is not able to genetically differentiate between the good and evil twin. But now German-based company Eurofins MWG Operon says it has found a way to do just that.  Read More
