Hidden algae diversity emerges in wheat fields across spring, summer and autumn‎

Intensive agriculture poses a significant threat to global biodiversity. However, one aspect of biodiversity in farmland is little studied: algae. Most people have seen algae growing in streams, lakes or the sea. However, algae have also adapted to survive in drier, harsher conditions on land. In fact, soil algae are thought to be responsible for about 6% of the vegetation production on Earth.

Homes are being abandoned as climate change accelerates migration out of rural Bhutan, new research shows.

Virtual reality game about zombie ants increases players' understanding of evolution‎

Playing a virtual reality game in which the player takes on the role of the zombie fungus Ophiocordyceps increases the players' understanding of how evolution works. Last summer, Utrecht University zombie ant researchers William Beckerson, Maite Goebbels and Charissa de Bekker invited visitors to the University Museum Utrecht to play the virtual reality game Zombie Ants VR: Definitive Edition. Comparisons between questionnaires completed before and after the game suggest that playing the game made the players more aware of how natural selection operates.

Philadelphia Mayor Cherelle Parker has proposed a US$1 fee on all Uber, Lyft and other rideshare trips in the city to begin in 2027. The projected $48 million annual revenue would go entirely to support the chronically underfunded Philadelphia school district, which faces a $300 million budget deficit.
