QUES: Marcin Woźniak and colleagues (2010) searched for specifically Slavic sub-group of R1a1a [M17]. Working with haplotypes, they found a pattern among Western Slavs which turned out to correspond to a newly discovered marker, M458, which defines subclade R1a1a7. This marker correlates remarkably well with the distribution of Slavic-speakers today. The team led by Peter Underhill, which discovered M458, did not consider the possibility that this was a Slavic marker, since they used the "evolutionary effective" mutation rate, which gave a date far too old to be Slavic. Woźniak and colleagues pointed out that the pedigree mutation rate, giving a later date, is more consistent with the archaeological record.

QUES: Other states with long histories of no death penalty include Wisconsin (the only state with only one execution), Rhode Island (although later reintroduced, it was unused and abolished again), Maine, North Dakota, Minnesota, West Virginia, Iowa, and Vermont. The District of Columbia has also abolished the death penalty; it was last used in 1957. Oregon abolished the death penalty through an overwhelming majority in a 1964 public referendum but reinstated it in a 1984 joint death penalty/life imprisonment referendum by an even higher margin after a similar 1978 referendum succeeded but was not implemented due to judicial rulings.

What state notably abolished the death penalty and then reintroduced it, and used it frequently?

QUES: Many energy markets, institutions, and policies have been developed to support the production and use of fossil fuels. Newer and cleaner technologies may offer social and environmental benefits, but utility operators often reject renewable resources because they are trained to think only in terms of big, conventional power plants. Consumers often ignore renewable power systems because they are not given accurate price signals about electricity consumption. Intentional market distortions (such as subsidies), and unintentional market distortions (such as split incentives) may work against renewables. Benjamin K. Sovacool has argued that "some of the most surreptitious, yet powerful, impediments facing renewable energy and energy efficiency in the United States are more about culture and institutions than engineering and science".

 Why do utility operators only ever accept renewable resources?
