A serious, but very uncommon side effect of IL-2 in high doses is capillary leak syndrome or vascular leak syndrome.. Capillary leak syndrome is a potentially serious disease in which fluids within the vascular system (veins and capillaries) leaks into the tissue outside the bloodstream.
Structure of the Earth. The interior structure of the Earth is layered in spherical shells, like an onion. These layers can be defined by their chemical and their rheological properties. Earth has an outer silicate solid crust, a highly viscous mantle, a liquid outer core that is much less viscous than the mantle, and a solid inner core.
Europa and Callisto, two of Jupiter's moons, may have liquid water oceans beneath a surface crust of ice. In the case of Europa, this ocean may have twice as much water as the whole Earth! Most of the water in the universe, though, is in the form of ice. This ice can come in many forms. On Earth, the ice is not as cold or hard as it is elsewhere in our solar system.
