Ocean algae get 'coup de grace' from viruses

2 days ago from Physorg

Scientists have long believed that ocean viruses always quickly kill algae, but Rutgers-led research shows they live in harmony with algae and viruses provide a "coup de grace" only when...

New study finds two amino acids are the Marie Kondo of molecular liquid phase separation

2 days ago from Physorg

The last several years have brought mounting evidence that the molecules inside our cells can self-organize into liquid droplets that merge and separate like oil in water in order to...

2 days ago from Physorg

FSU Assistant Professor of Biological Science Sophie McCoy and her team are proposing formal definitions for algae species and subcategories for the research community to consider: They are recommending algae...

Human activities promote disease-spreading mosquitoes; more study needed for prevention

3 days ago from Science Daily

Disease-spreading mosquitoes may be more likely to occupy areas impacted by human activities like pesticide use and habitat destruction, than they are areas less disturbed by humans, a recent study...
