Building a habitable planet: the physics and chemistry of planet formation Habitable planets must not only reside in a narrow range of distances from their stars, but they also must contain water and carbon. This is easier said than done. In this talk, IDr. Kress will discuss the chemistry in protoplanetary disks, and the physical processes by which earth-like planets form. ...
Interstellar material is highly processed when subjected to the physical conditions that prevail in the inner regions of protoplanetary disks, the potential birthplace of habitable planets. Polycyclic aromatic hydrocarbons (PAHs) are abundant in the interstellar medium, and they have also been observed in the disks around young stars, with evidence ...

Enacting Climate PolicyThe ClimateWorks Foundation supports public policies that prevent dangerous climate change and catalyze sustainable global prosperity. The foundation’s goal is to limit annual global greenhouse gas emissions to 44 billion metric tons by the year 2020 (25 percent below projections) and 35 billion metric tons by the year 2030 (50 ...

Pollination services and agroecosystems: Searching for sustainability? Claire Kremen will discuss how large-scale agriculture has come to rely on importing large numbers of honey bees, sometimes for thousands of kilometers, to farm fields for pollination. She will discuss recent colony losses in honey bees, and then ask the question, can wild pollinators take up the slack, and ...
