Updated 4:11 PM ET, Thu February 20, 2020. This artist's illustration shows newly discovered exoplanet K2-288Bb, 226. Photos: Weird and wonderful ... Flag as irrelevant
	Popular Science The New Horizons spacecraft just revealed secrets of the most distant object we've ever visited Popular Science Even as the New Horizons team celebrated their spacecraft's historic flyby of Pluto in the summer of 2015, they anguished over where to turn the probe next. After years of scouring the outer reaches of the solar system in vain with ground-based telescopes, ... Flag as irrelevant
	Forbes This Is Why Betelgeuse (Probably) Isn't About To Explode Forbes For months, skywatchers have enjoyed a view of the night sky that's wholly unfamiliar to anyone alive today: a sky where Betelgeuse, one of the 10 brightest stars in the sky, has dimmed to around #25, about the same as the stars in Orion's belt. The dimming ... Flag as irrelevant
	Scientific American Bumblebees Solve a 17th-Century Psychological Puzzle Scientific American By answering the question posed in Molyneux's problem the invertebrates may have demonstrated an ability to internally represent objects.

	Science Magazine Mysterious 'ghost' populations had multiple trysts with human ancestors Science Magazine The story of human evolution is full of ancient trysts. Genes from fossils have shown that the ancestors of many living people mated with Neanderthals and with Denisovans, a mysterious group of extinct humans who lived in Asia. Now, a flurry of papers ...

	Phys.Org Old carbon reservoirs unlikely to cause massive greenhouse gas release Phys.Org Permafrost in the soil and methane hydrates deep in the ocean are large reservoirs of ancient carbon. As soil and ocean temperatures rise, the reservoirs have the potential to break down, releasing enormous quantities of the potent greenhouse gas methane. Flag as irrelevant
	Science Magazine Disassembling 2D van der Waals crystals into macroscopic monolayers and reassembling into artificial lattices Science Magazine Although the exfoliation of monolayers of materials such as transition metal dichalcogenides produces high-quality electronic materials with low defect densities, the size of the monolayers is limited to the micrometer scale. Liu et al. modified this method by ... Flag as irrelevant
