Facial Sculptures Made from Random DNA Samples

DNA is essential to carbon-based life as we know it, but this is one of the few times that I’ve seen it used to create art. An artist created portrait sculptures from the analyses of genetic material that was collected in public places.

DNA in Flesh-Eating Flies’ Guts Reveal Biodiversity

When blowflies and flesh flies settle on dead animals, they aren’t just feasting on the carrion, they are in fact sampling their DNA. Scientists have demonstrated that this DNA persists long enough to be sequenced, allowing them to gain a quick and cost-effective snapshot of mammal diversity in otherwise inaccessible rainforest environments.

The UK has planned to fully sequence the genome of 100,000 Britons with cancer and rare diseases in an effort to decode their DNA, and hopefully find a cure for diseases. The project is unusual because it will decode the entire genome, not just parts of it.

MALBAC Offers More Efficient Way to Sequence DNA

single-cell-genomics-efficient

Sequencing DNA is nothing new, but it’s much harder to sequence the DNA of a single cell. In order to get enough DNA for sequencing, usually thousands or millions of cells are required. Finding out which mutations are in which cells is extremely difficult, making the mutations present in only a few cells, like early cancerous cells, almost impossible to detect.

Inherent Complexity of the Wheat Genome

An international team has produced a rough draft of wheat’s DNA sequence. The draft identifies many of its genes and makes it possible to identify thousands of potential genetic changes that could improve this crop. It’s been long considered one of the most important crop genomes.
