Geneticists are running ever-bigger and more expensive searches to identify the variants behind all kinds of traits and diseases, in the specific hope that their results will tell them something biologically interesting. They could show us more about how our bodies develop, for example, or point to new approaches for treating disease. But if Pritchard is right, then most variants will not provide such leads because they exert their influence in incidental ways.

Medicaid pays for most of the 1.4 million people in nursing homes... It covers 20 percent of all Americans and 40 percent of poor adults ... A combination of longer life spans and spiraling health care costs has left an estimated 64 percent of the Americans in nursing homes dependent on Medicaid. In Alaska, Mississippi and West Virginia, Medicaid was the primary payer for three-quarters or more of nursing home residents in 2015, according to the Kaiser Family Foundation.

Among the two dozen most populated states that determine the vast majority of Congress, there were nearly three times as many with Republican-tilted U.S. House districts. Traditional battlegrounds such as Michigan, North Carolina, Pennsylvania, Wisconsin, Florida and Virginia were among those with significant Republican advantages in their U.S. or state House races. All had districts drawn by Republicans after the last Census in 2010.

Without really good public transportation, it's very difficult to deal with inequality ... Transportation is about more than just moving people from point A to point B. It’s also a system that can either limit or expand the opportunities available to people based on where they live. In many cities, the areas with the shoddiest access to public transit are the most impoverished—and the lack of investment leaves many Americans without easy access to jobs, goods, and services.

While Norway wants to wean its own citizens off fossil fuels, it remains one of the world’s biggest oil producers and is revving up production, almost all of it for export. So even as the country tries to cut emissions and clean up its own carbon ledger at home, it is effectively doing the opposite abroad.

Until now, the oldest known fossils of our species dated back just 195,000 years. The Moroccan fossils, by contrast, are roughly 300,000 years old. Remarkably, they indicate that early Homo sapiens had faces much like our own, although their brains differed in fundamental ways.

Russia’s cyberattack on the U.S. electoral system before Donald Trump’s election was far more widespread than has been publicly revealed, including incursions into voter databases and software systems ... In Illinois, investigators found evidence that cyber intruders tried to delete or alter voter data. The hackers accessed software designed to be used by poll workers on Election Day ... In all, the Russian hackers hit systems in a total of 39 states

maggots are especially efficient at converting protein into body mass, making them a good choice for processing waste food. About 2.5 pounds of maggots can munch through five pounds of food waste in about four hours ... In the United States, however, there are currently restrictions on commercial operations feeding animals insects, though many other nations including Canada allow the practice. The European Union will begin allowing insect protein in fish farms beginning in July.

pre-trial detention rates—that is, the percentage of people who serve time while awaiting trial—have tripled nationwide since 1970. Still, as urban pre-trial detention rates have dropped precipitously, they’ve risen the most in the country’s rural counties with fewer than 250,000 residents. Between 1970 and 2013, rural pre-trial detention rates grew some 436 percent ... Since 1970, the rate of people from other jurisdictions serving time in rural jails has grown 888 percent.

Emissions have been reduced by approximately 1% each year since 2006, when California enacted its landmark law setting a target for cutting pollution that causes climate change. But to reach a newer, more ambitious goal for 2030, cuts will need to happen at about three times that pace.
