New method simultaneously measures flow and oxygen

An international research team headed by the Max Planck Institute for Marine Microbiology in Bremen, Aarhus University and the Science for Life Lab in Uppsala has developed tiny particles that measure the oxygen concentration ...

Data confirm link between respiratory stress and fish reproduction

A consistent metabolic ratio found across 133 Chinese marine and freshwater fish species provides new evidence in support of the idea that fish become sexually active—and spawn for the first time—in response to growth-induced ...

Male seahorses develop placentas to support their growing babies

Supplying oxygen to their growing offspring and removing carbon dioxide is a major challenge for every pregnant animal. Humans deal with this problem by developing a placenta, but in seahorses—where the male, not the female, ...

Mammals can breathe through anus in emergencies

Rodents and pigs share with certain aquatic organisms the ability to use their intestines for respiration, finds a study publishing May 14th in the journal Med. The researchers demonstrated that the delivery of oxygen gas ...

Arctic sponge survival in the extreme deep-sea

For the first time, researchers from the SponGES project collected year-round video footage and hydrodynamic data from the mysterious world of a deep-sea sponge ground in the Arctic. Deep-sea sponge grounds are often compared ...

Electric cable bacteria breathe oxygen with unheard efficiency

Ten years ago, researchers at Aarhus University, Denmark, reported the discovery of centimeter-long cable bacteria, that live by conducting an electric current from one end to the other. Now the researchers document that ...
