If any part is missing or broken, the watch stops working. The scientists who received the 2024 Nobel Prize in Physiology or Medicine discovered and characterized a component of that “watch” that no one previously understood — microRNA. Prior to its discovery by the laureates Victor Ambros of the University of Massachusetts C ...read more
"It's the economy, stupid."That was the phrase coined by political strategist James Carville to help the 1992 presidential campaign of Bill Clinton — who went on to defeat President George H.W. Bush.

One of the sadly neglected problems in modern science is the question of how best to keep beer cool once it has been poured into a glass. Now one scientist has come up with a novel solution by developing a mathematical model that determines the optimal shape of a beer glass that keeps beer cool.The problem is well known to generations of beer drinkers the world over. As soon as beer is poured into a glass, it starts to warm up. So an important goal is to minimize the heat entering the beer so th ...read more
