Human Y chromosome much older than previously thought
(Phys.org) —University of Arizona geneticists have discovered the oldest known genetic branch of the human Y chromosome – the hereditary factor determining male sex.
Scientists uncover genetic similarities between bats and dolphins
The evolution of similar traits in different species, a process known as convergent evolution, is widespread not only at the physical level, but also at the genetic level, according to new research led by ...
Common genetic ancestors lived during roughly same time period
Mitochondrial Eve and Y-chromosomal Adam—two individuals who passed down a portion of their genomes to the vast expanse of humanity—are known as our most recent common ancestors, or MRCAs. But many aspects ...
Sea urchins cope with rising CO2 levels
New key to organism complexity identified: Critical transcription factor co-exists in two distinct states
Berkeley Lab and UC Berkeley researchers have discovered that the transcription factor protein TFIID coexists in two distinct structural states, a key to genetic expression and TFIID's ability to initiate ...
Endangered lemurs' complete genomes sequenced, analyzed for conservation efforts
For the first time, the complete genomes of three separate populations of aye-ayes—a type of lemur—have been sequenced and analyzed in an effort to help guide conservation efforts. The results of the ...
New functions for 'junk' DNA?
DNA is the molecule that encodes the genetic instructions enabling a cell to produce the thousands of proteins it typically needs. The linear sequence of the A, T, C, and G bases in what is called coding ...
3 Qs: Seth Mnookin discusses the challenges and impacts of science writing
MIT Assistant Professor of Science Writing Seth Mnookin is the best-selling author of The Panic Virus, which examines how inaccurate scientific reports linking vaccines to autism have reverberated through the media, causing ...
Plans revealed to create Richard III genome (Update)
British scientists on Tuesday announced plans to create the complete genome sequence of infamous British king Richard III after his remains were found under a car park in 2012.
Genes show one big European family
From Ireland to the Balkans, Europeans are basically one big family, closely related to one another for the past thousand years, according to a new study of the DNA of people from across the continent.
Species conservation poised to benefit from DNA advances
A biologist at the University of York is part of an international team which has shown that advanced DNA sequencing technologies can be used to accurately measure the levels of inbreeding in wild animal populations.
Turtle genome analysis sheds light on the development and evolution of turtle-specific body plan
The Joint International Turtle Genomes Consortium, led by investigators from RIKEN, BGI, and Wellcome Trust Sanger Institute, has completed the genome sequencing of soft-shell turtle (Pelodiscus sinensis) and gr ...
Dark matter made visible before the final cut
Research findings from the University of North Carolina School of Medicine are shining a light on an important regulatory role performed by the so-called dark matter, or "junk DNA," within each of our genes.
Researchers identify genetic sequence that helps to coordinate synthesis of DNA-packaging proteins
Every time a cell divides it makes a carbon copy of crucial ingredients, including the histone proteins that are responsible for spooling yards of DNA into tight little coils. When these spool-like proteins ...
