Neanderthals R Us

 

Shady Side Academy has received the largest gift in the school’s 139-year history, a $15 million personal commitment from S. Kent Rockwell and his partner, Pat Babyak, in support of capital projects included in the school’s campus master plan.

John Fetterman’s stroke occurred on May 13, the Friday before the Tuesday primary in Pennsylvania.
His first brief statement about the stroke came out on Sunday, May 15.
First things first.

In the 17th century, words were sometimes coined by adding the suffix -tonian in a contemptuous manner. Other examples are sillytonian and simpletonian. The trend appears to have started after Muggletonian and Grindletonian, religious sects in 17th century England. Muggletonianism, for example, was started by two tailors one of whom was named Muggleton. According to Wiki, “Muggletonians avoided all forms of worship or preaching, and met only for discussion and socializing. The movement was egalitarian, apolitical, and pacifist, and resolutely avoided evangelism.”

The White House is coordinating a five-year research plan to study ways of modifying the amount of sunlight that reaches the earth to temper the effects of global warming, a process sometimes called solar geoengineering or sunlight reflection.
Who are these people?

Winter is coming.

Messrs. Tupy and Pooley describe the shift in argument as “the intellectual pilgrimage from worrying about running out of resources to worrying about running out of nature.” In this view, critics concede capitalism’s ability to produce the goods, but argue that this productive capacity itself is speeding us to our destruction. What use is everyone’s being able to afford a car if the price is making the climate unlivable?
But, the authors argue, it isn’t only that we produce more. It’s that we produce more in smarter ways, using fewer resources, and then using them in ways less harmful to the environment. --McCune

Neanderthals R Us

Prof Paabo is seen as one of the founders of the scientific discipline of paleogenomics. He won the 10m Swedish kronor (£800,000) prize this year, as did his father, Sune Bergstrom, who won the same Nobel Prize in 1982.
Scientists found a 40,000-year-old finger bone in the Denisova cave, in Siberia. Prof Paabo was able to sequence a sample of DNA and the results showed it was a previously unknown hominin - known as Denisovans. And it turned out Homo sapiens bred with Denisovans. In parts of South East Asia up to 6% of people's DNA is Denisovan.

Some of this genetic inheritance helps the body cope with low levels of oxygen, aids survival at high altitudes, and is found in present-day Tibetans.

His work shows there were already two distinct groups of hominins (Neanderthals and Denisovans) living in Eurasia when Homo sapiens spread from Africa. 
Analysis suggests these now extinct populations were small and relatively inbred and may not have been able to compete with rapidly expanding modern humans.

Further comparisons between Neanderthal DNA and humans from around the world showed their DNA was a closer match to humans coming from Europe or Asia.
This tells us that Homo sapiens bred with Neanderthals after migrating out of Africa around 70,000 years ago.
And you can still see the legacy of that today. Between 1-4% of modern human DNA comes from our Neanderthal relatives. (culled from BBC)
