How bacteria survive low oxygen environments

Researchers from ITQB NOVA, in collaboration with the Institut Pasteur in Paris, have shed light on the mechanisms that allow Clostridioides difficile, a pathogen that can only grow in oxygen-free environments, to be able ...

How weather affects crawfish harvests

The life cycle of a crawfish can be fairly straight forward. In the summer months, crawfish reproduce in underground mud burrows with a plug of mud on top of the burrow to protect them from predators. In late summer and early ...

Low-oxygen zones in Danish seas double in a year

The area of Danish seas affected by low oxygen levels—a problem triggered by climate change—has doubled in the space of a year, according to a university report published Friday.

Life in the shallows becomes a trap for baby sharks

Scientists can now explain how baby reef sharks tolerate living in the sometimes-extreme environments of their nurseries—but, they also say these habitats face an uncertain future which may leave newborn sharks 'trapped'.

Researchers unlock genomic secrets of scaly-foot snail

Despite an extreme environment characterized by high pressure, high temperature, strong acidity and low oxygen levels resembling living conditions in prehistoric times, hydrothermal vents harbor a diverse population of creatures, ...
