... of global warming, El Niño episodes, and even the drying
effects of rainforest clearing and burning itself." First, the biggest surprise noted thus far has been the great tolerance that this forest presented in the face of the severe drought that was created. As the moisture stored in the soil that sustai...

...arming. None of those runs showed the magnitude of drying
that actually occurred in southern Africa. When the models did include the Indian Ocean warming, southern Africa consistently dried out. The models also project that by 2049, monsoons across southern Africa could be 10% to 20% drier than the 1950-99 ...

of lipid-silica solutions produces an ordered porous nanostructure by a process known as molecular self-assembly. This can be visualized as a kind of tract housing. In the current experiments, however, the construction process is altered by the liv...
