Scientists from Duke University discovered that DNA contains a “built-in timer” that clocks the frequency with which mutations occur. Their research shows that DNA bases can change shape within a thousandth of a second, allowing them to temporarily morph into alternative states.
A team of researchers decoded the entire genetic information of the salamander axolotl. It is the largest genome ever to be sequenced. The “Mexican walking fish” could provide us with the foundation for novel insights into human tissue regeneration capacities.
CRISPR (Clustered Regularly Interspaced Palindromic Repeats) gene editing technology allows permanent modification of genes within organisms. It is considered a breakthrough in biotechnology ever since its discovery. Researchers from the University of Copenhagen (Denmark), led by Spanish researcher Guillermo Montoya, now went one step further. They discovered how Cpf1, a new type of molecular scissors, unzip and cleave DNA.
The largest genome-wide study of baldness identified over 250 novel genetic variants involved in its onset. Male pattern baldness is a major source of anxiety and depression among men and has been linked to serious cardiovascular diseases and prostate cancer.
The Francis Crick Institute of London was granted permission for genome editing in human embryos in order to study the complex processes involved in early miscarriage. This is the first time a research team has ever been exempt from the ban on human testing and represents an important step forward for science.
Researchers from Harvard University announced their plan to bring the woolly mammoth back to life using CRISPR/Cas9 within two years’ time. This would not only allow us to learn more about the prehistoric behemoth, but would also represent a first step towards preservation of endangered species.
An international collaboration of scientists successfully produced a stable artificial strain of bacteria with an extended “genetic alphabet”. The microbe encompasses two additional “X” and “Y” nucleotides, which enable it to store increased information within its genome, laying foundations for new forms of life.
A unique viral strain deemed Pandoravirus was discovered that spans a staggering 1 µm in diameter, beating the previous record holder by two-fold. The viral giant also possesses the largest viral genome ever discovered, most of which cannot be traced back to any of the existing domains of life.
A thrilling report has surfaced about the first baby being born as a result of a controversial fertilization technique, the spindle nuclear transfer. The procedure incorporates DNA from three “biological parents” to serve as the embryo’s genomic base, and is used to prevent mitochondrial diseases in infants.
There are people living among us, with capabilities we could easily call superpowers, and in most cases, they are not even aware of it. It turns out a tiny percentage of women actually develop a genetic condition called “tetrachromacy“, enabling them to see the world in hundred times more colors than the rest of us.
