This Sunday our bodies will get a long-needed pause from the detrimental effects of Daylight Saving Time. With a vast body of research showing the various health risks associated with the springtime switch, a York expert on biological clocks says the time is long overdue to make that pause permanent.
This Thursday marks the first day of summer in the Northern hemisphere, the longest day of the year. Living beings have evolved over many millennia to react to varying amounts of sunlight exposure, governing everything from sleep-wake cycles, seasonal changes and more, but the proteins responsible for responding to different light environments for non-visual purposes are an underexplored area of science. New research led by a York University Faculty of Science professor and former York researcher found that frogs have maintained a shocking number, and diversity, of these light-sensing proteins, called opsins, over evolutionary time.
Frogs display a remarkable diversity of species as a whole, but does the same hold true for their visual abilities? A new study led by York’s Faculty of Science sought to answer this question by collaborating with researchers in Australia, Belgium, Brazil, Cameroon, Ecuador, Equatorial Guinea, French Guiana, Gabon, Seychelles, Sweden, United Kingdom and the United States, to get a sample of a diverse array of frogs to study the visual pigments found in their eyes.
York University biological rhythms expert available to explain how internal clock works TORONTO, October 30, 2019 – When Canadians turn back their clocks one hour at 2 a.m. this Sunday, November 3, many will experience a shock to their bodies’ internal clock much like the jet lag experienced after flying across time zones, according to […]
York University bird expert is available for comment TORONTO, October 7, 2019 – The catastrophically high number of birds killed every year when they smash into glass windows is one of the main reasons why Canada and the United States have lost almost 3 billion birds since 1970, according to York University Professor Bridget Stutchbury. […]

York University to develop ‘BeeCSI’ tool to help Canada’s rapidly declining honey bees TORONTO, September 18, 2019 – When Canada’s honey bees are thriving, they produce honey and pollinate valuable crops like blueberries, apples and hybrid canola seeds. But the health of honey bees is declining, with more than a quarter of honey bee colonies […]

York University research could lead to new muscle cancer therapy TORONTO, May 22, 2019 – York University scientists have uncovered a unique set of genes that play a role in muscle cellular gene expression and differentiation which could lead to new therapeutic targets to prevent the spread of muscle cancer. The researchers analyzed gene networks […]
