Our planet is dominated by insects, and when and how insects took over the earth is a question that’s puzzled naturalists for centuries. In an incredible international effort, 100 scientists combined their molecular, computational biology, statistics, paleontology, and taxonomic expertise to uncover some surprising conclusions about when major groups of insects evolved.
As many as half of all stars in the universe lie in the vast gulfs of space between galaxies, an unexpected discovery that scientists believe could help solve mysteries regarding missing light and particles that theory had suggested should exist.
Astronomers have captured the best image ever of planet formation around an infant star. This revolutionary new image reveals in astonishing detail the planet-forming disk surrounding HL Tau, a Sun-like star located approximately 450 light-years from Earth in the constellation Taurus, including multiple concentric rings separated by clearly defined gaps. These structures suggest that planet formation is already well underway around this remarkably young star.

The ichthyosaur fills a crucial gap in the evolution of these dolphin-like predators, which thrived in Jurassic seas about 200 million to 145 million years ago. Scientists knew these reptiles evolved from land to the sea, since they have found fossils of both land-dwelling ancestors and the fast-swimming marine creatures, so paleontologists suspected there must be some in-between ichthyosaurs out there.

It's commonly believed that creativity is a process that involves connecting ideas and building on the past to create something new. But is it better to "think outside the box," using unrelated concepts to get the creative juices flowing, or to build on something more closely related to the problem one is trying to solve?
In 2011, astronomers were excited to discover a large cloud of gas careening toward the supermassive black hole that resides in the center of the Milky Way. But earlier this year, astronomers discovered that far from being eaten by the black hole the cloud of gas carried on its merry way, orbiting past the gravitational behemoth.

How does an individual's happiness level reflect societal conditions? A new article out today in the first issue of Policy Insights from the Behavioral and Brain Sciences (PIBBS) finds that similar to how GDP measures the effectiveness of economic policies, happiness can and should be used to evaluate the effectiveness of social policies.
