Qatar
Trump in the Middle East
U.S. President Donald Trump is on the first major overseas trip since his return to the presidency with a multi-stop tour through the Middle East. Trump arrived in Saudi Arabia yesterday, where he finalized a deal for $600 billion in investments by the Saudis in the U.S. and the sale of around $142 billion in arms to the Saudi government. Today, President Trump met with the interim president of Syria in Qatar, announcing that he would lift U.S. sanctions that have held back Syrian economic development for 45 years. While in Riyadh, Trump spoke on the negative influence of Iran on the region, and his interest in encouraging positive ties with the new leadership in Syria and the other countries in the region can be seen as keeping the U.S. as a counterweight. However, Mr. Trump also spoke about wishes for Iran’s success and prosperity with a change in strategy.

Mid-Atlantic Flash Flooding
Heavy rain in Maryland prompted the evacuations of two elementary schools and dozens of water rescues on Tuesday, as a slow-moving storm system continues to bring the risk of flash floods to the Mid-Atlantic. A flash flood emergency was issued for Westernport, Luke, and Barton in Allegany County, Maryland, where up to 5 inches of rain had fallen as of Tuesday afternoon. The National Weather Service warned of life-threatening flash flooding in Allegany County, Maryland, of low-water crossings, small creeks and streams, urban areas, highways, streets and underpasses. More than 15 million people across the Mid-Atlantic remain on alert for flooding and heavy rain. The most vulnerable areas will be from western Maryland down to southeastern Virginia.

Searching Out Hydrogen Supplies
An international team led by scientists from the University of Oxford and the University of Durham has identified the necessary geochemical conditions that should be present to find subterranean reservoirs of naturally occurring hydrogen gas. Hydrogen gas is a clean combustible fuel with the potential to be a viable alternative to polluting fossil fuels as a source of energy. Researchers believe chemical processes beneath the Earth’s crust have already potentially produced enough hydrogen gas to provide for 170,000 years of humanity’s energy needs, but locating the gas in sufficient quantities and developing proper methods of extraction are the greatest barriers to taking advantage of it. The team behind the report knows there are certain minerals that react with water to produce hydrogen. This report helps narrow down locations in the Earth’s crust where sediment conditions are ideal for hydrogen production and retention.
This map depicts locations around the world where sediments likely to produce hydrogen gas may be found, as highlighted in pink. Click on the map to learn more.

Q: What Chinese Autonomous region used to be occupied by the Portuguese?
A: Macau (Macao)
Macau (Macao) is a special administrative region of the People’s Republic of China (PRC). With a population of about 710,000 people and a land area of 12.7 square miles (32.9 sq km), it is the most densely populated region in the world. Macau is located on the southwestern corner of the Pearl (Zhu) River estuary and stands opposite the Hong Kong Special Administrative Region, which is some 40 miles (60 km) away on the eastern side of the estuary. Formerly a Portuguese colony, the territory of Portuguese Macau was first leased to Portugal by the Ming dynasty as a trading post in 1557. Portugal paid an annual rent and administered the territory under Chinese sovereignty until 1887, when Portugal gained perpetual colonial rights with the signing of the Sino-Portuguese Treaty of Peking. The colony remained under Portuguese rule until the 1999 handover to China.
