Warming climate is putting more metals into Colorado’s mountain streams

April 23, 2024

Warming temperatures are causing a steady rise in copper, zinc and sulfate in the waters of Colorado mountain streams affected by acid rock drainage. Concentrations of these metals have roughly doubled in these alpine streams over the past 30 years, a new study finds, presenting a concern for ecosystems, downstream water quality and mining remediation.

For Earth Day, CBS interviewed James Balog, environmental photographer, founder of Earth Vision Institute, and INSTAAR Affiliate. Balog has become one of the foremost chroniclers of human-caused climate change, as his cameras have tracked the dramatic effects – vanishing ice, rising seas, fires, and the toll climate change is taking on all living things. As shown in the 6-minute video interview, ~1200 of his prints were recently acquired by the Library of Congress.

5 NSF projects transforming how researchers understand plastic waste (NSF)

April 22, 2024

The U.S. National Science Foundation champions research on how plastic impacts the planet. In this article, they highlight five projects that are changing how researchers think about plastic and what happens after it is tossed away. One of these projects is a study led by Alexandra Jahn about how sea ice moves microplastics in polar regions. Working with her are colleagues from NCAR, U Washington, and WHOI.

April 17, 2024

A multi-university team of researchers, including four members of CU Boulder's Taylor Lab, have identified nearly a hundred genes associated with the birds’ spatial memory, or ability to recall the locations of objects. Their paper, published in the journal Current Biology, also suggests a potential trade-off may exist between having a solid long-term memory and being able to quickly ditch old memories to form new ones.
