New species of Allosaurus discovered in Utah
A remarkable new species of meat-eating dinosaur, Allosaurus jimmadseni, was unveiled at the Natural History Museum of Utah. The huge carnivore inhabited the flood plains of western North America during the Late Jurassic Period, between 157-152 million years ago, making it the geologically oldest species of Allosaurus, predating the more well-known state fossil of Utah, Allosaurus fragilis.

As they press their impeachment case against President Donald Trump, the Democrats need help from Chief Justice John Roberts. And they're not going to get it unless they ask for it. Far from securing the 67-vote majority needed to remove Trump from office, Democrats are desperate to flip a paltry four Republican senators just to be able to call witnesses.

Neil deGrasse Tyson: How science literacy can save us from the internet
The internet has become a tool to tribalize us, a place where opinions become identities in a fight to the death of who's right and who's wrong. As information continues to flow in, many of us lack the training to effectively sort opinion from fact. This leads to widespread disinformation. We need science literacy. With an understanding of how things work, or how to question how things work, we e
