  • Memories are made by breaking DNA — and fixing it

  • Two Broods of More Than a Trillion Cicadas Will Emerge in the U.S. This Year

    More than a trillion cicadas will be coming to the U.S. in an event that has not happened since Thomas Jefferson was U.S. president in 1803.  Two adjacent broods of the red-eyed flying cicadas will emerge from the ground in April, and residents in the Midwest and Southeast should brace themselves for a season of high-pitched buzzing.  2024 will mark the first time in more than 200 years that Brood XIX, which arrives every 13 years, and Brood XIII, which arrives every 17 years, will emerge at the same time.  The next co-emergence of these broods won’t happen for another 221 years.

  • Counterproductive Sustainable Investing: The Impact Elasticity of Brown and Green Firms

    The article develops a new measure of impact elasticity, defined as a firm’s change in environmental impact due to a change in its cost of capital. It shows empirically that a reduction in financing costs for firms that are already green leads to small improvements in impact at best. In contrast, increasing financing costs for brown firms leads to large negative changes in firm impact. Thus, sustainable investing that directs capital away from brown firms and toward green firms may be counterproductive, in that it makes brown firms more brown without making green firms more green.
