Genetic switch regulates transcription and replication in human mitochondria
Ribose-seq identifies and locates ribonucleotides in genomic DNA
Ribonucleotides, units of RNA, can become embedded in genomic DNA during processes such as DNA replication and repair, affecting the stability of the genome by contributing to DNA fragility and mutability. ...
New research finds Takahe have African cousins
New research from Massey University suggests that our Takahē have African cousins and that our Pūkeko are getting friendly with their Australian counterparts.
Study of ancient dogs in the Americas yields insights into human, dog migration
A new study suggests that dogs may have first successfully migrated to the Americas only about 10,000 years ago, thousands of years after the first human migrants crossed a land bridge from Siberia to North ...
New studies power legacy of UW-Madison research, 60 years later
Frederick Crane was a researcher under David E. Green in the mid-1950s, during the early days of the University of Wisconsin-Madison Enzyme Institute, when he made his defining discovery.

Genetics denote feral cat source
Feral cats arrived on Dirk Hartog Island in two separate waves, but are now reproductively isolated, according to genetic analysis.
Treasure trove of ancient genomes helps recalibrate the human evolutionary clock
Just like adjusting a watch, the key to accurately telling evolutionary time is based upon periodically calibrating against a gold standard.
Ancient human genome from southern Africa throws light on our origins
What can DNA from the skeleton of a man who lived 2,330 years ago in the southernmost tip of Africa tell us about ourselves as humans? A great deal when his DNA profile is one of the 'earliest diverged' – ...

Mitochondrial DNA of first Near Eastern farmers is sequenced for the first time
The mitochondrial DNA of the first Near Eastern farmers has been sequenced for the first time. In the research, published in the journal PLOS Genetics, experts analysed samples from three sites located in the ...
Domestication of dogs may explain mammoth kill sites and success of early modern humans
A new analysis of European archaeological sites containing large numbers of dead mammoths and dwellings built with mammoth bones has led Penn State Professor Emerita Pat Shipman to formulate a new interpretation ...
Organelles join mitochondria in signalling pathways creation
Scientists are a step closer to understanding mitochondrial pathways on a molecular level.
