Freshwater virus challenges biology’s rules

Dr. Jozef Nissimov and his team have uncovered a genome of a cyanophage (a virus that infects cyanobacteria) that defies conventional distinctions between viruses and cells.

The Canada Impact+ Research Training Awards are a groundbreaking initiative to support the next generation of researchers.

Algae may call to mind discoloured pool water or the green film floating to the top of your rain barrel, but they’re much more than a summertime nuisance. Algae have applications from carbon sequestra...

A discovery in Yellowstone National Park led to the development of PCR, the gold-standard COVID-19 tests used to fight the global pandemic.

Heterotrophic bacteria and archaea (“heteroprokaryotes”) drive global carbon cycling, but how to quantitatively organize their functional complexity remains unclear. We generated a global-scale unders...

New laboratory research shows that when viruses attack a species that forms toxic algal blooms, those thick, blue-green slicks that choke waterways and that threaten ecosystems, drinking water, and public health, what results might be even worse than before the infection.

Notices of changes are formal public announcements of planned services changes to applications and other products.

Harmful algal blooms dominated by Microcystis spp. occur throughout the world’s freshwater ecosystems, leading to detrimental effects on ecosystem services that are well documented. After decades of r...
