Marasmius rotula, the pinwheel mushroom, is a fungus in the family Marasmiaceae. Widespread in the Northern Hemisphere, it was first described scientifically in 1772 by Giovanni Antonio Scopoli. The mushrooms are characterized by thin whitish caps up to 2.0 cm (0.8 in) wide that are sunken in the center and pleated with scalloped margins. The wiry black hollow stalks measure up to 8.0 cm (3.1 in) long by 1.5 mm (0.06 in) thick. On the underside of the caps are widely spaced white gills, attached to a collar encircling the stalk. The mushrooms grow in groups or clusters on decaying wood such as moss-covered logs and stumps. Spore release is dependent upon sufficient moisture. Dried mushrooms may revive after rehydrating and release spores for up to three weeks, much longer than most gilled mushrooms. Although the mushrooms are not generally considered edible, they produce a unique peroxidase enzyme that is attracting research interest for use in bioengineering applications. (Full article...)

The discography of SZA, an American singer-songwriter, includes two studio albums, three extended plays (EPs), one live album, and forty-four singles, as of 2024. After self-releasing her first two EPs, SZA signed to the record label Top Dawg Entertainment, under which she released her 2017 debut studio album, Ctrl. The album peaked at number three in the United States Billboard 200, charted there for more than five years, and earned SZA some of her first Grammy nominations in 2018. After a five-year wait, during which SZA appeared in three top-10 collaborations, she released SOS, her second studio album. It became SZA's first number-one album in several countries, was the US's third best-selling album of 2023, and spawned "Kill Bill", the third best-selling single of the year worldwide. SZA's next projects are a deluxe edition of SOS and her third studio album, Lana. Ctrl and SOS have been ranked by Rolling Stone as among the 500 greatest albums of all time. (Full list...)
An oblique shock is a shock wave that, unlike a normal shock, is inclined with respect to the direction of incoming air. It occurs when a supersonic flow encounters a corner that effectively turns the flow into itself and compresses. This photograph shows an oblique shock at the nose of a Northrop T-38 Talon aircraft, made visible through Schlieren photography.
