"Streets" is a song by American rapper and singer Doja Cat (pictured). Appearing on her second studio album Hot Pink (2019), it is an R&B ballad with lyrics about a desire to return to a former romantic partner. The song became a sleeper hit around 15 months after the album's release—specifically, it went viral on the video-sharing application TikTok. It appeared in over 300,000 TikTok videos as background music for the "Silhouette Challenge", an online challenge in which participants danced while illuminated from behind with red lighting. Driven primarily by streams and digital sales, the song peaked within the top 20 of many national record charts, including the US Billboard Hot 100, and received platinum certifications in eight countries. "Streets" was sent to US contemporary hit radio stations as Hot Pink's seventh and final single on February 16, 2021. A corresponding music video premiered the next month, depicting Doja Cat's own version of the Silhouette Challenge. (Full article...)

Map of the Hawaiian–Emperor seamount chain

There are more than 80 identified volcanoes in the Hawaiian–Emperor seamount chain, a series of volcanoes and seamounts extending about 6,200 kilometres (3,900 mi) across the Pacific Ocean. The chain has been produced by the movement of the oceanic crust over the Hawaiʻi hotspot, an upwelling of hot rock from the Earth's mantle. As the oceanic crust moves the volcanoes farther away from their source of magma, their eruptions become less frequent and less powerful until they eventually cease to erupt altogether. The chain can be divided into three subsections. The first, the Hawaiian archipelago, consists of the islands comprising the U.S. state of Hawaii. The second part of the chain is composed of the Northwestern Hawaiian Islands. The oldest and most heavily eroded part of the chain are the Emperor seamounts, which are 39 to 85 million years old.

Rose robin

The rose robin (Petroica rosea) is a small species of passerine bird native to Australia. It tends to feed in the tops of trees, with insects and spiders forming the bulk of its diet, most being caught while it is in flight. Unlike other robins, it does not return to the same branch while foraging. Its prey consists of a variety of spiders and insects, including caterpillars, wasps, bugs such as cicadas and cinch bugs, beetles, weevils, flies and ants. This rose robin was photographed in the Blue Mountains National Park, near Woodford, New South Wales.
