Researchers at UD use ancient gene to study virus biology
Researchers at the University of Delaware have discovered that an ancient gene — ribonucleotide reductase (RNR), which occurs in all cellular life — provides important biological insights into the characteristics of unknown viruses in the sea. (more…)
When it comes to evolution, humans can learn a thing or two from primeval sea lampreys.
In the current issue of Nature Genetics, a team of scientists has presented an assembly of the sea lamprey genome – the first time the entire sequence has been decoded. The data is compelling as the sea lamprey is one of the few ancient, jawless species that has survived through the modern era.
The paper not only sheds light on how the venerable invasive species adapted and thrived, but it also provides many insights into the evolution of all vertebrates, species with backbones and spinal cords, which includes humans, said Weiming Li, Michigan State University fisheries and wildlife professor, who organized and coordinated the team.

An article written by Robert J. Shiller, the Arthur M. Okun Professor of Economics, was recently named one of the “top 20” articles in the 100-year history of the American Economic Review (AER), the premier journal in the field of economics.
“Do Stock Prices Move Too Much to Be Justified by Subsequent Changes in Dividends?” was published in the June 1981 edition of the AER and became a focal point of debate and research over the question of whether changes in stock market prices are driven by rational expectations — what’s called the efficient markets hypothesis — or by other forces.

A new study by a Cambridge University criminologist reveals just how dangerous it was to be a monarch in Europe before the modern era.
On 30 January 1649 Charles I was executed on a balcony overlooking Whitehall in central London. A huge crowd, restrained by ranks of militia, gathered to witness his beheading. An eye witness reported that his severed head was thrown down and his hair cut off while soldiers dipped their swords in his blood. (more…)
