Researcher aims to buy more time for dairy calves to absorb vital antibodies

Immunity problem affects nearly a third of calves worldwide

Researcher aims to buy more time for dairy calves to absorb vital antibodiesA University of Alberta dairy researcher is picking up where scientists left off 40 years ago, trying to solve an ongoing problem with calf health. Up to 30 per cent of dairy calves worldwide don’t get enough vital antibodies before birth to ward off the risk of diarrhea caused by E. coli and other bacteria.…

Sex matters when it comes to your susceptibility to infections

Anemia generates different immune responses in men and women

Sex matters when it comes to your susceptibility to infectionsA University of Alberta-led study shows that when it comes to susceptibility to infections and other health conditions, sex matters. The research, published in the journal Frontiers in Immunology, was led by U of A immunologist Shokrollah Elahi. Elahi and his team looked at how anemia – a condition in which a person lacks enough mature red…

Fungi fundamentals: the truth about mushrooms

Fungi have great names – turkey tail, pigskin poison, honey mushroom – and come in all shapes and sizes

Fungi fundamentals: the truth about mushroomsMy local nature club recently hosted a mushroom walk. No, that’s not where you take your pet mushroom for a walk. We visited some trails in central Ontario looking for different types of mushrooms, poisonous and edible. We weren’t foraging so we left the woods as we found them, although many others go to local…

Killer T cells could ignite immune response against cancer: study

Research brings cancer-killing cells to bear against a certain type of colorectal cancer tumour

Killer T cells could ignite immune response against cancer: studyA University of Alberta researcher has discovered how two signalling molecules recruit immune cells known as killer T cells to a specific type of colon cancer with more favourable patient outcomes. The finding may represent a therapeutic strategy to target other types of cancers. Kristi Baker, assistant professor in the Department of Oncology, examined tumours…

New device may improve life for people who have breathing challenges

Developers working to get it to market

New device may improve life for people who have breathing challengesA University of Alberta engineering duo is getting a boost from the university’s newly formed commercialization engine, imYEG, to get a new device for people with breathing challenges to market. Medical devices that assist people who have a low level of oxygen in their blood have evolved from large stationary tanks of compressed oxygen to…

Lakes in Canadian Rockies losing turquoise lustre as glaciers fade

Changing colour of alpine lakes may be a sign of worsening water quality, according to reports

Lakes in Canadian Rockies losing turquoise lustre as glaciers fadeAnother casualty of the disappearance of glaciers in the Canadian Rockies is the vanishing of the iconic turquoise of glacier-fed alpine lakes, according to a University of Alberta limnologist who documented the unfortunate change in the latest look at the health of Canada’s mountains. In an essay written for the fourth annual State of the Mountains…

Materials harvest electricity from wasted heat

New materials could harness energy from cellphones or body heat, and improve solar power, geothermal

Materials harvest electricity from wasted heatExtra heat is generated from any form of energy conversion – even with something as green as solar panels. But with up to 72 per cent of it left unused, there’s also great potential to harvest electricity from that waste. A University of Alberta researcher has successfully developed a way to figure out the chemistry…

Brain molecule helps ‘wake up’ cells that could help tackle MS: study

Fractalkine molecule showing promise for treating certain neurodegenerative disorders

Brain molecule helps ‘wake up’ cells that could help tackle MS: studyAn immunological molecule called fractalkine can boost the production of brain cells that produce myelin, a key factor in diseases such as multiple sclerosis, according to recent research from the University of Alberta. Myelin is an insulating layer around nerves that is gradually worn away by inflammation in multiple sclerosis and similar diseases. Without this…

Space designers take flight to test bioengineered knee cartilage in low gravity

Device built by U of A team could help researchers learn how osteoarthritis develops

Space designers take flight to test bioengineered knee cartilage in low gravityMembers of a University of Alberta student club are walking on air after testing samples of bioengineered knee cartilage in a reduced-gravity experiment competition. Amira Aissiou and Kirtan Dhunnoo of the University of Alberta Space Design Group strapped themselves in and went for a wild ride in the Canadian Space Agency’s Falcon 20 parabolic aircraft to get a…

Exploring bee behaviour opens new career possibilities

Tianna Tanasichuk's internship was a chance to gain experience – not learn about herself

Exploring bee behaviour opens new career possibilitiesWorking in the sunshine, surrounded by the soft hum of a dozen beehives this summer, Tianna Tanasichuk couldn’t help thinking of her recently passed Métis great-grandmother. “Whenever I was working with the bees, I felt like if she was here, she’d be proud of me, knowing I took this risk, of trying to grow by…
