New research from Cornell and the Smithsonian Institution deepens the geological understanding of Earth’s continents by testing and ultimately eliminating a popular hypothesis about why continental an...
Can humans endure long-term living in deep space?The answer is a lukewarm maybe, according to a new theory describing the complexity of maintaining gravity and oxygen, obtaining water, developing agri...
A group of international scientists led by Cornell is – more rigorously and systematically than ever before – evaluating if and how the stratosphere could be made just a little bit “brighter,” reflect...
