Stem cell study identifies enzyme with potential for cancer treatment

Research on how stem cells develop and differentiate in fruit flies has implications for human health

Stem cell study identifies enzyme with potential for cancer treatmentScientists have found a new mechanism responsible for regulating stem cells in fruit flies, with possible implications for cancer therapies. The study, published by University of Alberta biologists, identifies an inhibition mechanism of an enzyme called Myt1 kinase, which manages how stem cells develop and differentiate during organ development in fruit flies. “In addition to…

Tap water in an ultrasonic humidifier may pollute your airAs many Canadians prepare for the cold, dry winter months ahead, many of them will be using ultrasonic or cool-mist humidifiers in their homes. But using anything other than distilled water may be polluting the air in your home, according to new research by University of Alberta chemists. “Our study showed that operating an ultrasonic…

Diamond expertise unearths discoveries, economic opportunities

Researchers and employers are teaming up to train the next generation of diamond explorers

Diamond expertise unearths discoveries, economic opportunitiesThe interesting facet in searching for diamonds, according to University of Alberta expert Graham Pearson, is you don’t actually look for diamonds, you look for indicator materials that suggest they might be present. The same could be said for how mineral exploration and mining companies use the U of A to top up their workforce.…

Changing the way we think about weight and health

Changing the way we think about weight and healthMaxine Myre’s genesis as a researcher began with an investigation into the inflammatory responses of, among other things, fat cells. And although fat plays as important a role in the healthy function of people as any other component, the negative relationship we’ve developed between weight and health triggered a fascination within Myre. “I’m a fairly…
