Scientists recently discovered bats, like Tuvan throat singers and death-metal vocalists, produce sound using ventricular folds instead of vocal cords. A Danish biologist found bats use these for low-frequency calls. With their ability to also make extremely high-pitched calls, bats possess an unparalleled vocal range. The Center for Biological Diversity argues this makes them more akin to grindcore vocalists, who utilize both very low and very high frequencies.

The Center for Biological Diversity, a 501c3 nonprofit, works to secure a future for all species through science, law, and creative media. Check out our video to hear biodiversity-loving grindcore artists and see brutally cute bats. Learn more at biologicaldiversity.org or email us at center@biologicaldiversity.org.

The 1980s ushered in an era of "neo-liberal" economics, granting markets and corporations vast power, which led to escalating wealth inequality. A new global movement, Community Wealth Building, is now pushing back, fighting to democratize the economy and build wealth for the many. This movement is taking hold in diverse locations worldwide.

Renowned journalist Laura Flanders, host of The Laura Flanders Show on public television, will explain why this growing movement for a democratic economy may be the most important economic movement of our time. Flanders is an Izzy-Award winning independent journalist and bestselling author.

This panel discussion, presented on November 4, 2005, and published April 9, 2015, examines Portland's evolving approach to homelessness. It contrasts Mayor Bud Clark's 1985 "12-Point Plan" with the city's 2005 "10-Year Plan to End Homelessness," questioning how strategies have changed and why new outcomes are anticipated.

Moderated by Gretchen Kafoury (former city commissioner and Portland State University faculty), the panel featured three key community leaders. Erik Sten, City Commissioner, discussed the city's program. Genevieve Nelson, co-founder of Sisters of The Road, shared insights from a survey of 400 homeless individuals. Lisa Schroeder, a business owner and co-chair of the Downtown Retail Council, provided the downtown business perspective.
