The more centrally connected someone is within their social media network, the more likely that new words they use will become adopted into mainstream language, according to a new study published this week in PLOS Complex Systems by Louise Tarrade of École Normale Supérieure, France, and colleagues. Language evolves within a social context and variations in a language are always in competition with each other. In everyday language, words are constantly being created, but not all these words persist. In the new study, researchers analyzed more than 650 million tweets written in French between 2012 and 2014 to identify ...

Anyone who’s researched ways to lower their environmental impact has likely heard they should eat less meat, particularly beef. Even at scale, cows are an inefficient way to feed people — it takes nearly four tons of water to recoup one ton of beef, and many farming practices emit greenhouse gasses and pollutants. University of Pittsburgh researchers are the first to trace one of those pollutants, nitrogen, along the U.S. beef supply chain at the county level. They found high spatial disconnect between where ...

Virtual reality (VR) video games that combine screen time with exercise are a great way to get fit, but game designers face a major challenge – like with regular exercise, adherence to ‘exergames’ is low, with most users dropping out once they start to feel uncomfortable or bored. Computer scientists at the University of Bath believe they’ve found a solution: create exergames that use sensors to continuously measure a person’s emotional state while they exercise, then tweak the game – for instance, making ...
