Link between Alzheimer's disease and sex hormones
Link between Alzheimer’s disease and sex hormones
Western researchers reveal link between Alzheimer's disease and sex hormones Use of female animal models in the lab led to crucial finding Alzheimer's disease disproportionately affects women, who represent about two-thirds of those diagnosed with the late-onset type of the disease. Previous research has shown Alzheimer's is also more severe and progresses more rapidly in women, and women with Alzheimer's experience a steeper cognitive decline - loss of memory, attention, and the ability to communicate and make decisions - compared to men with the disease.

New nanomaterial may solve long-standing fuel cell issue
New nanomaterial may solve long-standing fuel cell issue
There is an urgent need to address climate change, making the development of sustainable energy alternatives more important than ever. While proton-exchange membrane fuel cells (PEMFCs) have shown great promise for energy production, particularly in the transportation industry, there is a long-standing problem with their durability and cost.

How do marine worms adapt to deep-sea conditions?
How do marine worms adapt to deep-sea conditions?
DNA sequencing of marine worms has revealed how they adapt to life 2,500 metres below the ocean's surface, where they experience extreme pressure conditions and temperature fluctuations. Maeva Perez is fascinated by marine worms. Her first encounter with these cold-blooded invertebrates dates back to her time at the University of Victoria, in British Columbia, where she was completing a master's in biology.

Stress, depression and... astrocytes
On World Mental Health Day, we look at how Ciaran Murphy-Royal and his research team work to prevent depression by acting on brain cells. The scientific literature is clear: chronic stress experienced in childhood increases the risk of illness in adulthood - everything from obesity and cancer to dependence and depression.

Simon Fraser researchers involved in major international antimatter breakthrough
Simon Fraser researchers involved in major international antimatter breakthrough
Antimatter is tied up in one of the world's greatest mysteries. Physics predicts that when we create matter, we also create equal amounts of antimatter. Yet there seems to be almost no antimatter in our universe, a fact that has long puzzled physicists. Now, physicists at Simon Fraser University, the University of Calgary, TRIUMF, the University of British Columbia, York University and the British Columbia Institute of Technology and research institutions from around the world have just answered a long-standing question that will lead to a deeper understanding of antimatter: Does it fall down?
