John Hainze— The Endangered Species Act is one of the premier environmental laws in the United States. It offers protection for endangered and threatened organisms both large and small—from orchids to insects to bears. That the Act does not differentiate between charismatic animals and those of a lesser pedigree is
Charles D. Canham— The northeast is one of the country’s most thoroughly forested regions, with forests covering two-thirds of the nine northeastern states. But that statistic belies the extraordinary wave of logging and clearing of land for agriculture that followed European settlement 400 years ago. In the Mid-Hudson Valley where
Barbara Schneider, Joseph Krajcik, Jari Lavonen, and Katariina Salmela-Aro— The bell rings as first hour is about to begin.

Frank M. Snowden— Some features of “Wuhan virus” are now apparent. In early December it began its career as a human disease after a “spillover” from its natural animal reservoir—possibly among bats—unleashing a severe respiratory disease. The megacity of Wuhan in central China was Ground Zero for this emerging infection,
Iain McGilchrist— It might seem reductive to link the highest achievements of the human mind, in philosophy and the arts, to the structure of the brain. I believe it is not. For one thing, even if it were possible for mind to be ‘reduced’, as we say, to matter, this
Judson Brewer— This is where the magic happens. Once behavior and reward are paired, the dopamine neurons change their phasic firing pattern to respond to stimuli that predict rewards.
