Respiratory ailments may hamper the body's ability to draw oxygen from the lungs, which is why patients' blood oxygen levels often need to be checked. New research now suggests that people could track those levels at home, using their smartphone.

If humans are to one day survive and thrive on Mars, ready access to breathable oxygen will be a necessity, and an interesting technology sent along with the Perseverance rover is beginning to show exciting promise on this front.

Leaves are impressive machines, converting sunlight, carbon dioxide and water into energy. Cambridge scientists have now created artificial leaves that can float on water, tapping into sunlight above it and water below to efficiently produce fuels.
-
In what's described as a key advancement for the future of systems that could help propel humans into deep space, scientists have demonstrated a method of extracting oxygen from water in microgravity using magnetism.

When treating patients for certain conditions, it's important to monitor their blood oxygen levels. A new sub-dermal photosensitive sensor provides a new means of doing so, plus it could one day be used to measure other blood-borne substances.

The Moon may look like a big dry ball, but there’s more water up there than you might expect. In a new study, scientists have shown that at least some of it could have been showered onto the lunar surface from the Earth’s atmosphere.

It's a sad fact that people with severe respiratory illnesses are often confined to hospitals, where they must breathe through ventilators. A new portable device that harvests oxygen from the air, however, may someday allow them to stay at home.
-
If there are two things that are essential to human life, they're water and oxygen – neither of which are easily available on the moon. Thanks to a new technique, though, astronauts may someday be able to harvest those elements from lunar soil.

Diabetic skin ulcers often take a long time to heal, sometimes even leading to complications that result in amputation. A new hydrogel is designed to help keep that from happening, by delivering oxygen directly to such wounds.
-
Most of us have in our busy lives wished there were more hours in the day. That wish actually came true billions of years ago – and that might be why we have so much oxygen now, as photosynthesizing microbes took advantage of the productivity boost.

New research is describing the discovery of a link between cognitive decline and a protein in red blood cells. The research found mice depleted of this protein suffered from rapid cognitive decline pointing scientists to a potential novel anti-aging treatment.

Researchers at Massachusetts General Hospital have identified an enzyme that may naturally protect the brain from damage caused by oxygen deprivation. This could be a potential drug target to prevent issues arising from strokes or heart attacks.
