New findings on why skeletal muscle stem cells stop dividing and renewing muscle mass during aging points up a unique therapeutic opportunity for managing muscle-wasting conditions in humans, says a new ÐßÐßÊÓƵ study.

Recently derived equations that describe development patterns in modern urban areas appear to work equally well to describe ancient cities settled thousands of years ago, according to a new study led by a researcher at the ÐßÐßÊÓƵ.

Applied mathematics student Stephen Kissler has received the highly competitive Gates Cambridge Scholarship for doctoral studies at Cambridge University, funded by Microsoft founder Bill Gates.

As climates change, the lush tropical ecosystems of the Amazon Basin may release more of the greenhouse gas carbon dioxide into the atmosphere than they absorb, according to a new study published Feb. 6 in Nature .

Scientists have known that shy toddlers often have delayed speech, but a new study by the ÐßÐßÊÓƵ shows that the lag in using words does not mean that the children don’t understand what’s being said.

For the first time ever, a team led by the ÐßÐßÊÓƵ has sequenced the internal bacterial makeup of the three major life stages of a butterfly species, a project that showed some surprising events occur during metamorphosis. The team, led by CU-ÐßÐßÊÓƵ doctoral student Tobin Hammer, used powerful DNA sequencing methods to characterize bacterial communities inhabiting caterpillars, pupae and adults of Heliconius erato , commonly known as the red postman butterfly. The red postman is an abundant tropical butterfly found in Central and South America.

The ÐßÐßÊÓƵ has been awarded a cooperative agreement worth up to $14.6 million from the Defense Advanced Research Projects Agency (DARPA) to develop a new technological system to rapidly determine how drugs and biological or chemical agents exert their effects on human cells. The project, called the Subcellular Pan-Omics for Advanced Rapid Threat Assessment, or SPARTA, will be conducted by an interdisciplinary CU-ÐßÐßÊÓƵ team led by Research Assistant Professor William Old of the chemistry and biochemistry department.

Heralding a new age of terrific timekeeping, a research group at JILA—a joint institute of the ÐßÐßÊÓƵ and the National Institute of Standards and Technology—has unveiled an experimental strontium atomic clock that has set new world records for both precision and stability.

If you were a shrew snuffling around a North American forest, you would be 27 times less likely to respond to climate change than if you were a moose grazing nearby. That is just one of the findings of a new ÐßÐßÊÓƵ assessment led by Assistant Professor Christy McCain that looked at more than 1,000 different scientific studies on North American mammal responses to human-caused climate change.
