Genetic differences between "identical" twins discovered

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

Implantable bio-patch grows bone where it's needed

Help could be on the way for people who don't have enough bone to support dental implants, who are missing bone due to a birth defect, or who have suffered bone-damaging injuries. Scientists at the University of Iowa have created an implantable collagen patch seeded with particles containing synthetic DNA, that instructs the patient's own cells to produce the protein that leads to bone growth.Read More

Is that a real Gucci? Just check its DNA

Earlier this year, we heard about a gun and a fogging system, both of which tag criminals with synthesized DNA. The idea is that when those people are apprehended later, they can be linked to the crime by analyzing the location- or event-specific DNA still on their skin or clothing. Now, scientists at the Technology Transfer Unit of Portugal's University of Aveiro are developing something similar – DNA "barcodes" that can be applied to products, then subsequently read as a means of identification.

Landmark decision? US Supreme Court rules human genes cannot be patented

In what is being ballyhooed as a landmark decision likely to set the course of DNA-based diagnostic and therapeutic medicine for the next several decades, the US Supreme Court unanimously decided on June 13 that human genes are not patentable. Rather than objects invented or discovered, human genes are henceforth to be treated as "naturally occurring phenomena," and hence fail the patentability test under 35 USC 101. As is usual in patent cases, however, the ruling contains delicate shades of meaning.Read More

Polymer patches could replace needles and enable more effective DNA vaccines

Taking a two-month-old in for vaccination shots and watching them get stuck with six needles in rapid succession can be painful for child and parent alike. If the work of an MIT team of researchers pans out, those needles may be thing of the past thanks to a new dissolvable polymer film that allows the vaccination needle to be replaced with a patch. This development will not only make vaccinations less harrowing, but also allow for developing and delivering vaccines for diseases too dangerous for conventional techniques.Read More

Understanding bat evolution could lead to new treatments for viruses and aging

Scientists believe the genes of virus-resistant and long-living wild bats might hold clues to treating cancer and infectious diseases in humans. The theory is that when bats started flying millions of years ago, something changed in their DNA that provides resistance to viruses and helps give them a relatively long life. The researchers hope a better understanding of bat evolution could lead to new treatments for disease and aging in humans. Read More

SelectaDNA system tags criminals by shooting them with a DNA gun

Imagine that you’re a police officer in the midst of a riot. While you may be able to apprehend the offenders closest to you, you can see plenty of other looters and vandals who you’re just not able to get to at the moment. Well, that’s where SelectaDNA’s High Velocity DNA Tagging System would come into the picture. At the heart of the system is a gun that shoots non-lethal pellets, which contain uniquely-coded synthetic DNA. Read More
