A new study challenges the popular theory that slow development of the prefrontal cortex—and its weak connectivity with brain reward regions—explains teenagers’ seemingly impulsive and risky behavior.
On the morning of August 17, gravitational waves arrived at Earth, tripping ultrasensitive detectors waiting for exactly this type of event.
When faced with a decision, people have varying ways of analyzing the choices. Give many people the same information, and they’ll all think about the situation differently, and often will choose slightly different options. As economists, we want to learn more about how people perceive and solve problems – including what sorts of situations are too difficult for people to analyze well.
Scientists have detected gravitational waves coming from the collision of two neutron stars, and, for the first time, captured their image.
When LIGO detected its first gravitational wave back in September 2015, I was pretty excited to say the least. As part of a decades-long endeavor, our whole team was ecstatic to observe gravitational waves – which are literally ripples in space – caused by two black holes smashing together. It was the first time that Einstein’s predictions about these tiny ripples were directly confirmed. Just this month, the Nobel Prize in physics was awarded to three of the founders of our international collaborative effort – Rainer Weiss, Kip Thorne and Barry Barish – in recognition of this first observation.
