Sequencing an entirely complete human genome has been the work of decades. Twenty years ago, the Human Genome Project (HGP) declared their work finished, with an asterisk. Even a decade later, fully eight percent of the genome — so-called “junk DNA” — was beyond our understanding. But the idea of …

Researchers have sequenced analyzed the genome of the Atlantic puffin (Fratercula arctica), a small auk with a large head and a colorful bill. Using the genome-wide resequencing data, they’ve also identified four main puffin population clusters consisting of (i) Spitsbergen (High Arctic), (ii) Canada, (iii) Isle of May, and (iv) …

An international team of researchers has successfully sequenced and analyzed the genome of the kākāpō (Strigops habroptilus), a flightless parrot endemic to New Zealand. Published in the journal Cell Genomics, their results shows that even after 10,000 years of inbreeding, the species is in surprisingly good genetic health. The kākāpō …

Scientists have extracted and sequenced mitochondrial DNA from a partial femur of an ancient dog that lived in Alaska 10,150 years ago. Their results, published in the Proceedings of the Royal Society B, demonstrate that the animal belonged to a lineage of dogs that diverged from Siberian dogs around 16,700 …

Epigallocatechin-3-gallate (EGCG), a polyphenol found in the leaves of green tea (Camellia sinensis), may increase levels of the natural anti-cancer protein p53, often referred to as ‘the guardian of the genome,’ according to a new study led by Rensselaer Polytechnic Institute scientists. Zhao et al. provide insights into the mechanisms …

A team of researchers from the United Kingdom and Canada has sequenced the genome of the white-faced capuchin (Cebus imitator), a medium-sized New World monkey of the family Cebidae.

The Australian lungfish (Neoceratodus forsteri), a species of lungfish native to the Mary and Burnett River systems in south-eastern Queensland, has a genome size about 14 times larger than that of humans.

An international team of scientists has sequenced and analyzed the entire nuclear genome of the scimitar-toothed cat Homotherium latidens. Their results demonstrate that this extinct species was highly divergent from all living cat species and did not undergo any detectable gene flow with living cat species after their initial diversification …

A team of researchers from Imperial College London, the University of Oxford and CABI has successfully sequenced the genome of Alexander Fleming’s original fungal strain behind the discovery of penicillin, now classified as Penicillium rubens, and compared it to those of two ‘high producing’ industrial strains of Penicillium rubens and …
