When Bridges Collapse; the Value of New Perspectives on Climate Change Impact
The United States is considering a $1 trillion budget proposal to update infrastructure, including its crumbling bridges.

Trees help clean the air, provide habitat for wildlife, help conserve soil and water, and are the source of an entire industry that support jobs and the economy. Land management agencies like the Bureau of Land Management, the National Park Service, the US Fish and Wildlife Service, and the US Forest Service oversee hundreds of millions of acres of forests across the country. more »
Julien de Wit On the Discovery of Seven Temperate, Nearby Worlds; Planets may harbor conditions suitable for sustaining liquid water — and thus life
All of these planets are the best targets found so far to search for signs of life, and it is remarkable that they are all transiting the same star. This means that the system will allow us to study each planet in great depth, providing for the first time a rich perspective on a different planetary system than ours, and on planets around the smallest main sequence stars. Only 39 light years away from Earth! more »
