The Almighty Squabble Over Who Gets to Name Microbes

Baker named the group of deep-sea microbes collected in 2009 Helarchaeota—after the Norse goddess of the underworld.Officially speaking, Helarchaeota falls into a category called Candidatus—a designation reserved for microbes that haven’t earned a proper scientific name yet.“We are finding new kinds of life right and left,” says Karen Lloyd, a microbial ecologist at the University of Tennessee, Knoxville.

Research finds microplastics in fish muscle tissue

“This higher ingestion rate for flounder could be due to microplastics accumulating in marine sediments which makes up more of their diet compared to other species, or it could be because the flounder samples were all obtained from the Waitemata Harbour, which is closer to Auckland as a potential microplastic source,” she said.
