With newly passed legislation, San Francisco is now the largest city in the country to not require a minimum number of parking spaces for new developments.

Fireworks can unleash a shower of toxins into soil and water, and scientists are only beginning to figure out what that means for human health.

In 1958, writer Rachel Carson began her exhaustive research on the effects of widespread pesticide use for her next book, Silent Spring. Over the next four years, she built up an airtight case showing how the world’s most powerful chemical companies were harming animals, plants, and people. Her effort was also a race against time, as she struggled against an aggressive form of breast cancer. In the second episode of a four-part special series on leadership, HBR Editor in Chief Adi Ignatius and Harvard Business School professor and historian Nancy Koehn trace the modern environmental movement back to Carson’s pioneering reporting and powerful prose. They discover lessons in how to strengthen your resilience, gather your energy and skills for a coming challenge, and why caretaking is an act of leadership.

Vision-and-Language Navigation (VLN) requires an agent to follow natural-language instructions, explore the given environments, and reach the desired target locations. These step-by-step navigational instructions are crucial when the agent is navigating new environments about which it has no prior knowledge. Most recent works that study VLN observe a significant performance drop when tested on unseen environments (i.e., environments not used in training), indicating that the neural agent models are highly biased towards training environments. Although this issue is considered as one of the major challenges in VLN research, it is still under-studied and needs a clearer explanation. In this work, we design novel diagnosis experiments via environment re-splitting and feature replacement, looking into possible reasons for this environment bias. We observe that neither the language nor the underlying navigational graph, but the low-level visual appearance conveyed by ResNet features directly affects the agent model and contributes to this environment bias in results. According to this observation, we explore several kinds of semantic representations that contain less low-level visual information, hence the agent learned with these features could be better generalized to unseen testing environments. Without modifying the baseline agent model and its training method, our explored semantic features significantly decrease the performance gaps between seen and unseen on multiple datasets (i.e. R2R, R4R, and CVDN) and achieve competitive unseen results to previous state-of-the-art models.

Bill McKibben and Elizabeth Kolbert join David Remnick to talk about the twin crises of our time: the coronavirus pandemic and the climate emergency. What can one teach us about the other? During the COVID-19 national emergency, the Trump Administration has loosened auto-emissions standards, and has proposed easing the controls on mercury released by power plants, among other actions. With protesters no longer able to gather, construction on the controversial Keystone Pipeline has resumed. Still, McKibben and Kolbert believe that the pandemic could remind the public to take scientific fact more seriously, and possibly might change our values for the better. “When we get out of detention,” McKibben says, “I hope that it will be a reminder to us of how much social distancing we’ve been doing already these last few decades,” by focussing on technology and the virtual world. In the pleasure of human contact, he hopes, “we might begin to replace some of the consumption that drives every environmental challenge we face."

Every week, for a quarter of a century now, WEMU's David Fair has delivered "Issues of the Environment," which has brought information involving our community's environmental health. He has welcomed numerous guests to discuss matters, such as managing food waste, monitoring climate change, and fighting hazardous chemicals like PFAS. This week, David welcomes Washtenaw County water resources commissioner Evan Pratt for a look back at 25 years of "Issues of the Environment."
