A man walking his dog on Vancouver Island found a leg with a foot in a black sneaker on a beach. The authorities are trying to get a DNA sample from it.
|DNA Reveals that Silky Anteaters Are Seven Species|

The silky anteater (Cyclopes didactylus) has previously been recognized to be a single species divided into several sub-species. But a new genetic analysis, published in the Zoological Journal of the Linnean Society, suggests that this enigmatic mammal is not one species, but seven separate ones. Silky anteaters belong to the genus Cyclopes in the family [...]

We can add one more thing to the list of traits affected by genetics: how our bodies respond to a particular diet. Research in animal models with different genetics shows that one diet really doesn't fit all, and what works for some may not be best for others, according to a new study.
|Working out the genetic risk for ADHD|

Genetics play a strong part in the development of attention-deficit/hyperactivity disorder (ADHD), but the path from a gene to risk for the disorder has remained a black box to researchers.. A new study suggests how the risk gene ADGRL3 (LPHN3) might work. ADGRL3 encodes the protein latrophilin 3, which regulates communication between brain cells. According to the study, a common variation of the gene associated with ADHD disrupts its ability to regulate gene transcription - the formation of mRNA from DNA that leads to expression of the gene.
|Patients' individual genomes may affect efficacy, safety of gene editing|

Gene editing has begun to be tested in clinical trials, using CRISPR-Cas9 and other technologies to directly edit DNA inside people's cells, and multiple trials are recruiting or in planning. A new study raises a note of caution, finding person-to-person genetic differences that may undercut the efficacy of gene editing or, more rarely, cause potentially dangerous 'off target' effects. It suggests that gene editing may need to be adapted to each patient's genome.

A team of scientists at Caltech has created the smallest version of the Mona Lisa ever - out of DNA. The work is described in a paper appearing in the journal Nature. In 2006, Caltech Professor Paul Rothemund developed a method, called ‘DNA origami,’ to fold a long strand of DNA into a prescribed shape. [...]
|Cyanobacteria in lakes: Risks linked to loss of diversity|

The composition of cyanobacterial communities in peri-alpine lakes has become increasingly similar over the past century. Climate warming and a period of eutrophication have favored in particular potentially toxic species which can adapt rapidly to environmental changes. These are the findings of an study analyzing DNA extracted from sediment cores.
