China
Military Action Raises Alarm
The United States has sent spy planes to monitor the South China Sea after China sent 24 military aircraft into Taiwan’s airspace, which China claims as a part of its territory. Taiwan recently applied to join the Comprehensive and Progressive Agreement for Trans-Pacific Partnership, which includes many neighboring nations in the South China Sea to negotiate deals on labor and trade market access. China’s Foreign Ministry opposes the recognition of Taiwan as a separate entity from China and joining such partnerships. The overflights by Chinese military aircraft is seen as a direct response to Taiwan’s application.

Polynesian Migration Mapped
Scientists at Stanford University have used DNA sequencing to recreate the timeline by which ancient Polynesians migrated eastward from Samoa, settling in island chains across the Pacific Ocean along the way. Polynesia consists of a broad, triangular area of the Pacific Ocean filled with various island chains, with New Zealand, Hawaii, and Rapa Nui (Easter Island) at the corners. The Polynesians who settled the islands share common languages and culture. Stanford researchers analyzed DNA samples from 430 individuals living on 21 different islands to identify the genetic patterns common to Polynesians while also blocking results from European and African DNA that had crept in over the last two centuries.

Ancient Footprints Found in Park
Human footprints believed to be up to 23,000 years old have been found at White Sands National Park in New Mexico. Archaeologists believe they are the oldest known footprints in North America. The ancient footprints, believed to have belonged to teenagers and small children, were buried in layers of soil in the park. Scientists from the US Geological Survey examined seeds that were lodged within the tracks to calculate the approximate age of the footprints. Previously, scientists and archeologists believed the earliest settlement of humans in North America was between 11,000 to 12,000 years ago.

Q: Running 5,525 miles (8,891 km), what is the world’s longest international border between two countries?
A: Canada and the United States
Canada is the second largest country in the world, behind Russia. Its border with the United States is the world’s longest international border, with the Russia-Kazakhstan border and the Chile-Argentina border coming close behind. Canada shares a border with 13 states—Alaska sharing the longest border at 1,538 miles (2,475 km). Most Canadians live relatively near the U.S. border, with about 90% of all Canadians living within 100 miles (160 km) it.
