Comments Off on Discovery of ancient middle finger bone completely upends what we know about human migration

Archaeologists have discovered an ancient middle finger bone in Saudia Arabia, and it could completely change what we know about human migration. An 85,000-year-old bone belonging to Homo sapiens marks the first evidence of humans that scientists have found in the Nefud Desert. This is also the first time Homo sapiens bones of that age have been discovered anywhere outside Africa. The current theory of human migration posits that Homo sapiens migrated en masse in a movement known as “Out of Africa” about 60,000 years ago in a single, contained wave. But this newly-discovered bone suggests that people migrated out of Africa in multiple different phases, at least 20,000 years earlier than we thought.

Trump administration prioritizes rural areas over cities in infrastructure spending

Comments Off on Trump administration prioritizes rural areas over cities in infrastructure spending

The Trump Administration has re-prioritized which kinds of communities, and what kinds of projects, receive funding from the popular $500 million transportation grant program known as TIGER (Transportation Investment Generating Economic Recovery). “More than 64 percent of this round of TIGER funding was awarded to rural projects, a historic number that demonstrates this Administration’s commitment to supporting the country’s rural communities,” the Transportation Department said when it announced the grant recipients in March. Democratic strongholds such as New York City , Chicago and Los Angeles received zero funding from these grants, while projects in blue states that were funded focused primarily on those states’ Trump-supporting regions. This means much more money for rural roads and rail projects, and less for bike infrastructure, green-ways, and sustainable urban design projects. The TIGER grant program was first established through the American Recovery and Reinvestment Act of 2009, also known as the stimulus package or economic recovery bill, under President Obama . While the discretionary funds are an important tool for the White House, they represent only a small percentage of the Department of Transportation’s distribution of $50 billion each year through the highway trust fund. After trying to eliminate the program twice, Trump recently signed a massive spending bill into law that tripled the program’s budget. Now, it seems, his administration has found a use for TIGER. Related: 69% of Republicans believe global warming’s seriousness is “generally exaggerated” Trump is not the first president to be accused of using the program to favor his political supporters. In 2013, at the start of President Obama’s second term, two-thirds of the TIGER infrastructure funding went to districts represented by Democrats in Congress. Much of this Obama-era funding went towards projects such as bike and pedestrian infrastructure while sometimes giving only the bare minimum required by law to rural areas. In addition to its shift towards rural communities, the Trump Administration, with its well-publicized focus on trade, is also prioritizing upgrades to port infrastructure in Alabama, Maryland and Louisiana.
