The Wikipedia article of the day for April 30, 2018 is Louisiana Purchase Exposition dollar.
The Louisiana Purchase Exposition dollar was a commemorative gold coin series dated 1903. The coins were designed by Charles E. Barber, Chief Engraver of the United States Bureau of the Mint. The pieces were issued to promote the Louisiana Purchase Exposition held in 1904 in St. Louis. They were struck in two varieties at the urging of exposition authorities, including numismatic promoter Farran Zerbe: one depicted former president Thomas Jefferson, and the other, the recently assassinated president William McKinley. The price for each variety was $3, the same cost whether sold as a coin, or mounted in jewelry or on a spoon. Although not the first American commemorative coins, they were the first in gold. They were intended to help fund the Exposition, originally scheduled to open in 1903. Congress authorized the coins in 1902, but they did not sell well, and most were later melted. They regained their issue price by 1915, and are now worth between a few hundred and several thousand dollars, depending on condition.

The Wikipedia article of the day for April 29, 2018 is Subfossil lemur.
Subfossil lemurs are primates from Madagascar, especially the extinct giant lemurs, represented by subfossils (partially fossilized remains) dating from nearly 26,000 to around 560 years ago. Almost all of these species, including the sloth lemurs, koala lemurs and monkey lemurs, were living around 2,000 years ago, when humans first arrived on the island. The extinct species are estimated to have ranged in size from slightly over 10 kg (22 lb) to roughly 160 kg (350 lb). The subfossil sites found around most of the island demonstrate that most giant lemurs had wide distributions. Like living lemurs, they had poor day vision and relatively small brains, and developed rapidly, but they relied less on leaping, and more on terrestrial locomotion, slow climbing, and suspension. Although no recent remains of giant lemurs have been found, oral traditions and reported recent sightings by Malagasy villagers suggest that there may be lingering populations or very recent extinctions.

The Wikipedia article of the day for April 24, 2018 is 1867 Manhattan, Kansas earthquake.
The 1867 Manhattan earthquake struck Riley County, Kansas, in the United States on April 24. The strongest earthquake to originate in the state, it measured 5.1 on a seismic scale based on reports of how strongly it was felt in the area. Its epicenter was near the town of Manhattan. On the Mercalli intensity scale, its maximum perceived intensity was VII, “very strong”. There were reports of minor damage in Kansas, Iowa, and Missouri, according to the U.S. Geological Survey. It was felt as far away as Indiana and Illinois, and perhaps Ohio, though the latter reports have been questioned. Manhattan is near the Nemaha Ridge, a long anticline structure that is bounded by several faults. A 2016 hazard map from the U.S. Geological Survey estimated a 1% or lower risk for a major earthquake in Kansas for the following year, though the nearby Humboldt Fault Zone continues to pose a threat to the city, and scientists from the agency think an earthquake of magnitude 7.0 remains possible.
