Blue blood on ice: How an Antarctic octopus survives the cold

An Antarctic octopus that lives in ice-cold water uses an unique strategy to transport oxygen in its blood, according to research published in Frontiers in Zoology. The study suggests that the octopus's specialized blood ...

New material steals oxygen from the air

Researchers from the University of Southern Denmark have synthesized crystalline materials that can bind and store oxygen in high concentrations. Just one spoon of the substance is enough to absorb all the oxygen in a room. ...

Cell behaviour in low oxygen conditions mapped

(Phys.org) —Research at the University of Liverpool has explained how cells behave when placed in a low oxygen environment, a development that could have implications for cancer patients and other serious illnesses.

Decoding material fluxes in the tropical ocean

How is vital oxygen supplied to the tropical ocean? For the first time, oceanographers at GEOMAR Helmholtz Centre for Ocean Research Kiel were able to make quantitative statements regarding this question. They showed that ...

Size matters for creatures of cold polar waters

Scientists at the Universities of Liverpool, Plymouth, and Radboud, Netherlands, have challenged the view that giant animals are found in polar seas because of a superabundance of oxygen in cold water.

Migrating animals add new depth to how the ocean 'breathes'

The oxygen content of the ocean may be subject to frequent ups and downs in a very literal sense—that is, in the form of the numerous sea creatures that dine near the surface at night then submerge into the safety of deeper, ...

Oxygen-sensing microrobots

(Phys.org) —When the retina's supply of blood and oxygen runs low, physicians have to react quickly to preserve a patient's eyesight. But up until now there have been no methods sensitive enough to measure how well the ...
