The animals themselves had fairly short legs, four to six meters in length, lived between 166 and 66 million years...

The evil, the dark, the nasty, the mean, the bitter, the abysmal, the bad, or anything else negative can claim particular diversity. In English, for example, there are 66 percent more words for bad emotions than for good feelings. And when native English speakers describe someone with an unpleasant personality, they can use 77 percent more vocabulary than when describing someone with a sunny disposition. The bad knows more faces, more variations than the good. This has been known in...
Important milestone: Astronomers have analyzed the atmosphere of an exoplanet more comprehensively than ever before - and gained important insights into the chemistry and formation of such planets. Using spectral data from the James Webb Space Telescope, they also detected sulfur dioxide on the hot gas giant WASP-39b for the first time, in addition to water, carbon dioxide, carbon monoxide, sodium and potassium. The enrichment of the atmosphere with heavy elements and oxygen also provides indications of how and where...
