United States
Generations Driving the Spread
Since initial loosening of travel restrictions in mid-2020, individuals aged 20-49 have been the source of an estimated 65% of all new COVID-19 infections in the United States, according to new research published in Science. Researchers analyzed aggregated mobility data from the cellphones of more than 10 million Americans and found those between the ages of 20 and 49 was the only group sustaining disease reproduction values (R) well above one. According to a map included in the study, individuals aged 35-49 contribute to onward spread at relatively stable rates across the United States (bottom map), while those aged 20-34 contributed to spread at greater rates in southern, south-western, and western regions (top). While the study found mobility to increase the fastest among individuals aged 18-24 following the re-opening of restaurants, night clubs, and other venues, their mobility rates did not increase above those of older individuals. The study cites the high average number of contacts for those aged 20-49 as the primary reason for the group’s influence on furthering the spread of disease.

Colombia
Legal Status for Venezuelans
This week, Colombian President Iván Duque announced Venezuelan migrants and refugees would be granted temporary legal status in the country for 10 years if they register with the government. An estimated 5.4 million Venezuelans have fled from violence and economic collapse in their country since 2014, prompting one of the largest migration crises in the world. An estimated 1.7 million Venezuelans, nearly a third of those who have fled, entered into neighboring Colombia. The influx of migrants into the country of 50 million has angered some Colombians, who perceive increased competition for jobs and services. The new temporary protection statute will allow Venezuelan migrants currently residing in the country illegally to work and access essential services including healthcare, with an option to apply for a resident visa after 10 years. Those migrants who do not register with the authorities may be subject to deportation. During the announcement, President Duque called on the international community to provide increased financial support for the humanitarian crisis, estimated by some experts to be the most underfunded in modern history.

Bahamas
Group Rescued After 33 Days
The U.S. Coast Guard rescued three Cuban nationals who had been stranded on the deserted Anguilla Cay in the Bahamas for 33 days. While performing routine patrols in the Caribbean on Monday, aircrews spotted three people waving makeshift flags on the uninhabited cay located in a chain of islands between the Florida Keys and Cuba. Crews dropped a radio, food, and water to the group before performing the rescue yesterday. The stranded trio, comprised of two men and one woman from Cuba, had been travelling by boat when their vessel capsized in rough waters and they swam to safety on the island five weeks ago. Coast Guard officials reported the group had survived by eating coconuts and were in remarkably good shape. Though no serious injuries were reported, the shipwrecked party was transported to the Lower Keys Medical Center in Florida for examinations.

Q: At a surface area of 143,244 mi² (371,000 km²), what is the largest in-land body of water on Earth?
A: Caspian Sea
Although the name may be deceiving, the Caspian Sea is actually a very big lake. With its location spanning from Europe and into Asia, this lake has an area of more than 143,000 square miles (370,000 square kilometers) – larger than the area of Japan. The Caspian Sea has not always been a salt lake. Studies have shown that up until 11 million years ago, the lake connected to the rest of the world’s oceans via the Sea of Azov, the Black Sea, and the Mediterranean Sea. Besides the industries of shipping and fishing, the Caspian Sea is also a valuable source of petroleum and natural gas.
