The universe is expanding much quicker than previously thought, according to researchers in Germany, leading scientists to suggest it may be more than 2 billion years younger than past estimates.

The Royal Swedish Academy of Sciences announced the 2018 Nobel Prize in Economics to a duo for their work on how the world can achieve sustainable growth.
The prize was divided equally to William D. Nordhaus of Yale University and to Paul M. Romer of New York University's Stern School of Business, both Americans, who have "designed methods for addressing some of our time's most basic and pressing questions about how we create long-term sustained and sustainable economic growth," the academy said Monday in a press release.

In a survey of 50 Nobel Prize winners in the sciences, medicine and economics, more than a third of the respondents said damage to the environment brought about by issues like over-population and climate change, was the biggest threat to mankind. Twenty-three percent said nuclear war was their top concern, while six percent said theirs was "the ignorance of political leaders"—with two of the winners naming Trump specifically.
