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.

Traditional surface finishing technologies, including chemical etching and sandblasting, often rely on ecologically harmful processes. Fusion Bionic offers a sustainable alternative with its Direct Laser Interference Patterning (DLIP) technology.

DLIP creates functional surface textures inspired by nature, mimicking structures found on lotus leaves and shark skin. This innovative approach earned Fusion Bionic recognition as a runner-up for the prestigious Ray of Hope Prize.

TEDx events are independently organized by volunteers, with detailed guidelines available here. This talk explores how buildings can breathe like plant leaves while cleaning polluted water.

Architect and biodesign researcher Shneel Malik showcases this vision with "Indus," a wall featuring a novel biomaterial with microalgae for photosynthesis. Bridging futuristic techniques with cultural practices, her work empowers artisans and revolutionizes water interaction. At UCL's Bio-Integrated Design Lab, Malik investigates transforming urban systems into biological processes, fostering a circular economy. Learn more about TEDx at ted.com/tedx.

The artificial leaf technology mimics natural photosynthesis, converting carbon dioxide, water, and sunlight into storable fuels like hydrogen. This innovation offers a path to cleaner energy, supporting net-zero emissions goals and sustainable solar fuel production as an alternative to fossil fuels.

Dr. Qian Wang, a researcher at the University of Cambridge and author of over 20 publications on photocatalysts, leads this research. Her work focuses on generating renewable energy through artificial photosynthesis, addressing challenges in creating efficient, scalable systems. She recently discussed this technology at a TEDx event. Learn more at TEDx.

Bioplastics are often marketed as an eco-friendly alternative to traditional plastics. However, this "green" image can be misleading. Many bioplastics are not compostable and cause similar environmental harm, particularly in oceans, as their petroleum-based counterparts.

It's crucial to recognize that not all bioplastics offer a sustainable solution. To truly combat plastic pollution, we must move beyond all forms of plastic.

Every September, Alaskan wood frogs prepare for winter by crawling into leaf litter and freezing solid. This remarkable survival strategy involves two-thirds of their body water turning to ice,

Every September, Alaskan wood frogs prepare for winter by crawling into leaf litter and freezing solid. This remarkable survival strategy involves two-thirds of their body water turning to ice, causing their hearts to stop beating.

After six months in this frozen state, the frogs thaw out and resume normal activity. For more details, visit: biodiv.us/2vNg0PN
