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.

Sequencing of Comb Jellies’ DNA Reveals that they Preceded Sponges

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.

UK to Sequence Genome of 100,000 Patients

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.

A new study indicates that DNA strands can be coaxed to fold into shapes in a matter of minutes. This could speed up progress in the field of DNA origami.

Inherent Complexity of the Wheat Genome

bread-wheat

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.

First Electron Microscope Image of DNA Double Helix

dna-double-helix

The structure of DNA was originally discovered by using X-ray crystallography, which involves scattering X-rays off atoms in crystallized arrays of DNA to form complex patterns of dots on photographic film. Images were then interpreted using complex mathematics. These new images are now direct pictures of DNA strands, seen through an electron microscope, which sees electrons rather than photons.

Prolific Changes in the Human Genome in the Past 5,000 Years

human-chromosomes

Human populations have grown exponentially in the past 5,000 years, and new genetic mutations arise in each new generation. Humans have a vast abundance of rare genetic variants in the protein-encoding sections of the genome. A new study tries to clarify when many of these rare variants arose.

Synthesizing a Flu Vaccine Without the Virus

flu-virion

A new vaccine strategy, which uses synthetic messenger RNA (mRNA) instead of proteins purified from viruses, could make flu shots cheaper, safer, and easier to produce. German scientists have shown that they have been able to protect mice, ferrets, and pigs against influenza.
