DUBAI, United Arab Emirates (AP) — Yemen's Iranian-allied Houthi rebels attacked a Saudi airport and military base with a bomb-laden drone Tuesday, an assault acknowledged by the kingdom as Middle East tensions remained high between Tehran and Washington. There were no immediate reports of injuries or damage.
Earth's Moon only ever shows us one face. It's locked into its current orientation, with a permanent nearside and farside, but it wasn't until the Apollo missions that scientists were able to see just how different the two sides really are. The nearside, with its sea of dark gray basins standing in contrast to the brilliant white powder that covers the rest of its face, varies dramatically from the farside, which is marked with countless smaller craters in a more uniform distribution.The debate over how the Moon's split personalities developed has raged for decades, but new research seems to indicate that one of the possible explanations does indeed hold water. The theory, that Earth's Moon was struck by a tiny dwarf planet long ago, is the subject of a new research paper published in Journal of Geophysical Research: Planets.Using computer models to simulate what may have happened to the Moon's surface long ago, researchers suggest the most likely scenario seems to be the collision between the Moon and a very large body. The impact of a dwarf planet as large as 480 miles across would have struck what we see today as the Moon's nearside at a speed of 14,000 miles per hour.This theory stands in contrast to other proposed explanations, including the theory that Earth may have once had not one Moon, but two. The two-moon theory suggests that Earth's moon duo may have at one point collided and merged, leaving the Moon as we see it today looking oddly unsymmetrical.The dwarf planet collision scenario assumes that whatever the body that struck the Moon was, it was in its own path around the Sun and just happened to be in the right place at the right time to strike Earth's natural satellite. This, the researchers say, would also explain why the crust on the farside of the Moon is different than that of its nearside."We demonstrate that a large body slowly impacting the nearside of the Moon can reproduce the observed crustal thickness asymmetry and form both the farside highlands and the nearside lowlands," the paper explains. "Additionally, the model shows that the resulting impact ejecta would cover the primordial anorthositic crust to form a two‐layer crust on the farside, as observed."

Schiff said in a statement Wednesday that the department has offered to start turning over 12 categories of information that his panel had subpoenaed, and he said the process should be completed by next week. It was a rare instance of cooperation as the Trump administration increasingly stonewalls demands from Democratic-controlled House committees for documents and testimony to follow up on Mueller’s investigation into Russia’s interference in the 2016 election.
Mississippi's fetal heartbeat law which bans abortions after approximately six weeks could be blocked or upheld by Judge Carlton Reeves.
The HUD secretary faced a tough hearing before the House Financial Services Committee on Tuesday.
The US has hit China where it hurts by going after its telecom champion Huawei, but Beijing's control of the global supply of rare earths used in smartphones and electric cars gives it a powerful weapon in their escalating tech war. A seemingly routine visit by President Xi Jinping to a Chinese rare earths company this week is being widely read as an obvious threat that Beijing is standing ready for action. Xi's inspection tour "is no accident, this didn't happen by chance," said Li Mingjiang, China programme coordinator at the S. Rajaratnam School of International Studies (RSIS) in Singapore.
The U.S. administration is considering Huawei-like sanctions on Chinese video surveillance firm Hikvision, media reports show, deepening worries that trade friction between the world's top two economies could be further inflamed. The restrictions would limit Hikvision's ability to buy U.S. technology and American companies may have to obtain government approval to supply components to the Chinese firm, the New York Times reported https://nyti.ms/2MfgBS3 on Tuesday. The United States stuck Huawei Technologies on a trade blacklist last week, effectively banning U.S. firms from doing business with the world's largest telecom network gear maker, in a major escalation in the trade war.
I have nothing against old people — I'm one of them. But maybe it's time to add a maximum age limit to our minimum age requirement for our presidents.
