Bursch, Expedition Four flight engineer, works on the Elektron Oxygen Generator in the Zvezda Service Module on the International Space Station (ISS). Image courtesy of NASA On Earth, we have a constant supply of fresh air. We breathe in oxygen and breathe out carbon dioxide. These gases ...
However, that doesn’t mean that there’snomoisture in the air. It still snows on the Prairies when temperatures are in the double-digits below zero. These snowfalls just aren’t very productive. The lower moisture of a ...
They draw liquid hydrogen and oxygen from the ET at an amazing rate, equivalent to emptying a family swimming pool every 10 seconds! The fuel is partially burned in a pre-chamber to produce high pressure, hot gases that drive the turbo-pumps (fuel pumps). The fuel is then fully burned ...
Stem cells are foundin most tissues throughout the body, and each type does different things. With the ability to separate into numerous cell types, mesenchymal stem cells have multipotent properties, making them attractive for clinical applications. During the Mayo Clinic-sanctioned research on the ...
training and is attributed to similar mechanisms including, capillary density, increased red blood cell volume and hemoglobin mass, all resulting in more oxygen getting to the muscles7. Repeated bouts of HIIT produce as much as 25–35% increases in mitochondrial content in as few as 6–7 ...
However, the mining process does have an added advantage—breaking apart ilmenite to release the titanium also releases oxygen, which is necessary for everything from rocket fuel to breathable air. So, instead of going after the titanium specifically, early lunar mining efforts might focus on the...
Orange is an extremely unusual shade of aurora, as there is not one particular component of the atmosphere that can produce that colour on its own. Similar to how the red from oxygen and blue from nitrogen combine into purple, though, researchers have found...
If something is a physical property, it is possible to measure the property through observation that does not irreversibly changing the material that has the property. Chemical properties, on the other hand, are attributes of a substance that allow for a chemical change, often irreversible. They ...
People have been working on cancer immunotherapy, which turns a patient’s immune system against cancer cells, for decades. Scientists in the field have developed drugs that produce some remarkable results in patients with aggressive, late-stage cancers. But most next-generation cancer immunotherapies...
