Humanities Scholars Overturn Biology, Discover Trait-Based Politics In Fear Response

There are examples of positive political campaigns- Ronald Reagan appealed to what America could be, for example- but even that message of hope had an undercurrent of fear, namely that if things did not change, America would stay morassed in 1970s stagfla ...

Uncharacterized Genes: Evolutionary Rates And A Clue

Humans have an unclear number of genes- ab initio gene finding and comparative gene finding yield different totals (see the Human Genome Project for details)- but it is likely in the low 20,000s and those genes make nearly as many proteins. The functions ...

Single Genetic Mutation Produced Thick Hair 30,000 Years Ago

An animal model of recent human evolution found that a single mutation produced several traits common in East Asian people, from thicker hair to denser sweat glands. They also modeled the spread of the gene mutation across Asia and North America, concludi ...

Molecules Assemble In Water- A Hint About The Origins Of Life?

The base pairs that hold together two pieces of RNA, the older cousin of DNA, are some of the most important molecular interactions in living cells. Many scientists believe that these base pairs were part of life from the very beginning and that RNA was o ...

PiRNAs That Control Where Epigentic Factors Are Placed In Genome Discovered

If a genome is the blueprint for life, then the chief architects are  the molecular regulators of epigenetics, say Yale School of Medicine researchers. In the past 20 years, scientists have discovered that some proteins, epigenetic factors, traverse the s ...
