Was this the ocean's ugliest sea monster?
Its teeth were found at the end of a narrow, trunk-like extension of its head and its eyes were perched on either side of a long, rigid bar. The so-called Tully Monster could be the most repulsive looking creature to ever have roamed the oceans. For decades, the ancient monster had been one of the great fossil enigmas: It was discovered in 1958, first described scientifically in 1966, yet never definitively identified even to a major animal group. But a Yale University-led team of paleontologists have determined the 300- million-year-old beast - which grew only a foot long - was a vertebrate, with gills and a stiffened rod supporting its body. "It's so different from its modern relatives that we don't know much about how it lived," study leader Dr Victoria McCoy said. "It has big eyes and lots of teeth, so it was probably a predator."
Watch out for your Tinder competition
To swipe left, or swipe right? It's the big choice at the heart of Tinder and other dating apps as hook-up hunters trawl through faces for a potential candidate. But now researchers have unearthed a hidden and interesting pattern that may be giving some an unexpected boost - or the opposite. An Australian study found women were more likely to rate a face as attractive if they thought the preceding face was attractive - but the same was true when they thought the preceding face was ugly. Earlier studies had found that when participants were asked to make quick judgements about a rapid sequence of faces, the most recently seen images were likely to be rated more attractive. Until the new study, it still wasn't clear whether this bias was true when attractiveness was simplified to a choice between attractive or not attractive, as favoured by some online dating sites.
