Speedy nanorobots could someday clean up soil and water, deliver drugs

June 29, 2021

CU Boulder researchers have discovered that minuscule, self-propelled particles called “nanoswimmers” can escape from mazes as much as 20 times faster than other passive particles, paving the way for their use in everything from industrial clean-ups to medication delivery.

Cat-borne parasite Toxoplasma induces fatally bold behavior in hyena cubs

June 23, 2021

New research finds that the same parasite found in house cats (and often in their guardians) prompts hyena cubs in the wild to act dangerously bold near lions, often resulting in their death.

Human-driven climate change only half the picture for krill, key species in the Southern Ocean

June 15, 2021

New research about the fate of krill—one of the most abundant species on Earth—during this century has important implications for not only the Antarctic food web, but for the largest commercial fishery in the Southern Ocean.

Mountain residents underestimate wildfire risk, overestimate preparedness

June 11, 2021

Hannah Brenkert-Smith has studied the role of residents' choices in wildfire risk for two decades, with one goal being to improve mitigation programs. Her most recent work near Bailey, Colorado, concludes residents often overestimate their preparation and underestimate their risk.

What could such a green spring mean for fire season?

June 2, 2021

So far, 2021 is one of the 10 wettest years on record since 1872 in the Denver area. Chelsea Nagy discusses what a wet spring and resulting plant growth in the Front Range could mean for the rest of the year.

How plankton hold secrets to preventing pandemics

May 17, 2021

Whether it’s plankton exposed to parasites or people exposed to pathogens, a host’s initial immune response plays an integral role in determining whether infection occurs and to what degree it spreads within a population, new CU Boulder research suggests.

To prevent next pandemic, scientists say we must regulate air like food and water

May 13, 2021

A group of 39 researchers from 14 countries say we need to change how we regulate the air we breathe inside buildings, like we do the food we eat and the water we drink, in order to reduce disease transmission and prevent the next pandemic.
