New research suggests that there is plenty of oxygen available in the subsurface ocean of Europa to support oxygen-based metabolic processes for life similar to that on Earth. In fact, there may be enough oxygen to support ...

(PhysOrg.com) -- First it was grapes, then cockroaches, and now snails have become the latest organism to generate electricity through an implanted biofuel cell. The process works similarly in all three situations: the electricity ...
In the course of global climate change, scientists are observing the increase of low-oxygen areas in the ocean, also termed oxygen minimum zones (OMZs). Large-scale OMZs exist, for example, in the Pacific off the coast of ...

(Phys.org) —A pair of researchers from the University of Zurich in Switzerland has found that pre-adaptive traits, (which they call exaptations) appear to be far more common than adaptive traits. In their paper published ...
Early life forms on Earth may have been able to generate metabolic energy from sunlight using a purple-pigmented molecule called retinal that possibly predates the evolution of chlorophyll and photosynthesis. If retinal has ...

Any animal ascending a mountain experiences a double whammy of impediments: The air gets thinner as it also becomes colder, which is particularly problematic for creatures struggling to keep warm when less oxygen is available. ...

Take a wild, common forest-dwelling mouse-like rodent, known as a vole, and subject it to 13 rounds of selection for increased aerobic exercise metabolism, and what do you get? A mighty "mouse" with a 48 percent higher peak ...

Much of life on planet Earth today relies on oxygen to exist, but before oxygen was present on our blue planet, lifeforms likely used arsenic instead. These findings are detailed in research published today in Communications ...
