The cherry trees in the nation’s capital are confused by Earth’s changing climate, with the iconic blossoms appearing earlier than expected because of the unusually warm winter.
Washington Mayor Muriel Bowser and the National Park Service announced Wednesday that Washington’s 3,700 cherry blossom trees would reach peak bloom this year from March 22-25. That’s several days earlier than observers and experts had expected.“This has been a challenging year to read the trees,” said Jeff Reinbold, NPS superintendent for the national mall and memorial parks.
The end results, Reinbold said, are trees that he compared to a hormonal teenager. “There’s a lot going on in there,” he said.The early bloom, by itself, isn’t a huge problem, unless the temperatures drop suddenly again now that the vulnerable blossoms are emerging. “An early frost would definitely damage the blossoms,” Reinbold said.
Cherry Blossom Festival President Diana Mayhew said this year’s bloom dates aren’t unprecedented, but they’re the second earliest she had witnessed in 23 years with the organization. As a result, her organization has accelerated their own timetable, moving up multiple events planned at the Tidal Basin by a week.
Mayhew said she and city officials are expecting a boom year for the festival, which typically signals the unofficial start of D.C.’s tourist season. The 2020 cherry blossom season was essentially wrecked in real time by the creeping shadow of the COVID-19 pandemic, which was moving across the country just as the festival was holding press conferences. Organizers finally were forced to cancel most in-person events.
The 2021 festival took place fully under pandemic restrictions while last year’s season drew an estimated 1.1 million visitors—close to the pre-pandemic average of 1.5 million. This year, Mayhew said she hopes to match or exceed those pre-pandemic numbers.

Frontiers | Rare earths stick to rare cyanobacteria: Future potential for bioremediation and recovery of rare earth elementsBiosorption of metal ions by phototrophic microorganisms is regarded as a sustainable and alternative method for bioremediation and metal recovery. In this study, 12 cyanobacterial strains, including 7 terrestrial and 5 aquatic cyanobacteria, covering a broad phylogenetic diversity were investigated for their potential application in the enrichment of Rare Earth Elements through biosorption. A screening for the maximum adsorption capacity of cerium, neodymium, terbium, and lanthanum was conducted in which Nostoc sp. 20.02 showed the highest adsorption capacity with 84.2 - 91.5 mg g-1. Additionally, Synechococcus elongatus UTEX 2973, Calothrix brevissima SAG 34.79, Desmonostoc muscorum 90.03, and Komarekiella sp. 89.12 were promising candidate strains, with maximum adsorption capacities of 69.5-83.4 mg g-1, 68.6-83.5 mg g-1, 44.7-70.6 mg g-1, and 47.2-67.1 mg g-1 respectively. Experiments with cerium on adsorption properties of the five highest metal adsorbing strains displayed fast adsorption kinetics and a strong influence of the pH value on metal uptake, with an optimum at pH 5 to 6. Studies on binding specificity with mixed-metal solutions strongly indicated an ion-exchange mechanism in which Na+, K+, Mg2+, and Ca2+ ions are replaced by other metal cations during the biosorption process. Depending on the cyanobacterial strain, FT-IR analysis indicated the involvement different functional groups like hydroxyl and carboxyl groups during the adsorption process. Overall, the application of cyanobacteria as biosorbent in bioremediation and recovery of Rare Earth Elements is a promising method for the development of an industrial process and has to be further optimized and adjusted regarding metal-containing wastewater and adsorption efficiency by cyanobacterial biomass.
