As human uses increasingly threaten the Earth’s natural spaces, a new ecological model developed by University of Guelph researchers suggests that so-called mosaic ecosystems may be near a “tipping point” and that conserving these landscapes requires taking a longer and more balanced view.
The number of outdoor cats in the city of Guelph is eye-raising, and these cats are more likely to be found in low-income residential areas, according to a new study from the University of Guelph.
University of Guelph plant scientists have shown for the first time how an ancient crop teams up with a beneficial microbe to protect against a devastating fungal infection, a discovery that may benefit millions of subsistence farmers and livestock in developing countries.
University of Guelph researchers studying the intimate structure of edible fats are getting help from the United States Department of Energy.
Human relationships and interactions form our social network. Crickets are no different, except their networks are simpler. A U of Guelph researcher found the insects’ social network remains mostly unchanged each year and their social structure is conserved over evolutionary time.
Researchers including a University of Guelph scientist have recorded the only known example of prehistoric pollen caught in explosive mid-discharge from a fossil flower. The team describes this “freeze-frame” fossilized pollen release – preserved in amber more than 20 million years ago — in a paper describing a new genus of fossil nettle plants.
Tipping in restaurants is a widespread practice in need of reform, according to a new study conducted by University of Guelph professors. They found tipping poses significant challenges for restaurants, with managers seeing difficulties in hiring chefs and maintaining a cordial workplace environment. Surprisingly, servers welcomed changes to how tips are divvied up, even at the risk of less income.
New research from the University of Guelph and Nipissing University shows that people who help others are more desirable to the opposite sex, have more sexual partners and more frequent sex.
Cancer treatment in people could be transformed thanks to a study on treating cancer in animals led by researchers from the Ontario Veterinary College (OVC) at the University of Guelph. Injecting oncolytic viruses (viruses that target cancer cells) intravenously into the spleen allows immune responses to be boosted much more rapidly and to much higher magnitudes than traditional vaccine methods.
Why do women have lower rates of heart failure than men for most of their lives? University of Guelph researchers have uncovered a possible clue – an actin binding protein called “CapZ” that also protects against heart attacks.Now they’ll be studying how its levels are affected by gender and aging, backed by a prestigious Catalyst Grant from the Canadian Institutes of Health Research (CIHR). Their research may lead to new therapeutic treatments for reducing heart problems and extending lives of both men and women.
Pipelines carrying crude oil to ports in British Columbia may spell bad news for salmon, according to a new University of Guelph-led study. Exposure to an oil sands product – diluted bitumen – impairs the swimming ability and changes the heart structures of young salmon.
A new University of Guelph study has found that parents, and especially fathers, play a vital role in developing healthy behaviours in young adults and helping to prevent obesity in their children. When it came to predicting whether a young male will become overweight or obese, the mother-son relationship mattered far less than the relationship between father and son.
An almost entirely accidental discovery by University of Guelph researchers could transform food and biofuel production and increase carbon capture on farmland. By tweaking a plant’s genetic profile, the researchers doubled the plant’s growth and increased seed production by more than 400 per cent.
A University of Guelph research team found that cells produce proteins under low oxygen levels in significantly different ways than classic examples based on artificial lab studies.
Soy isoflavones and peptides may inhibit the growth of microbial pathogens that cause food-borne illnesses, according to a new study from University of Guelph researchers.
The University of Guelph's Ontario Veterinary College is doing a clinical trial with the U.S. National Cancer Institute’s Comparative Oncology Trials Consortium. Researchers will evaluate the effectiveness of the therapeutic agent rapamycin for treating osteosarcoma in dogs by delaying or preventing metastases.
Harnessing an invasive fish species sounded like a promising conservation tool to help reverse the destruction wreaked by zebra mussels on endangered native mollusks in the Great Lakes – except that it won’t work, says a University of Guelph ecologist. In a novel twist on invasive species ecology, a research team led by integrative biology professor Joe Ackerman found that the round goby fish – an invader in Ontario waters — only makes matters worse for native mollusks already driven to near-extinction by an earlier zebra mussel invasion.
A University of Guelph professor has uncovered the “secret” to staying strong as we age – superb fitness. Geoff Power found elderly people who were elite athletes in their youth or later in life – and who still compete as masters athletes — have much healthier muscles at the cellular level compared to those of non-athletes.
Led by researchers from the Ontario Veterinary College (OVC), the team found that homeless youth with pets are less likely to engage in potentially harmful behaviour, more likely to open up to veterinarians about their personal challenges and generally less depressed.
Experienced bumblebees prefer not to share their foraging knowledge with newbies. Two bees were allowed to visit the flowers at a time – one more experienced resident and one newcomer. When the newcomer bees tried to copy the choices of seasoned foragers, the more experienced bees frequently attacked them and tried to evict them from flowers.
Low levels of pesticides can impact the foraging behaviour of bumblebees on wild flowers, changing their floral preferences and hindering their ability to learn the skills needed to extract nectar and pollen, according to a study co-authored by a University of Guelph professor.
Detailed exploration of tiny insect brains has become much easier using new methods for imaging and 3D image reconstruction. The researchers used this X-ray imaging to produce hundreds of image slices that can be re-constructed by a standard laptop computer into a high resolution 3D model.
Salmon have an ace up their sleeve -- or in their gills -- when facing challenging conditions that could affect their hearts, according to a study led by a University of Guelph researcher. The researchers found that carbonic anhydrase (CA) can help improve delivery of oxygen to the heart.
New research from the University of Guelph on the brain and memory could help in developing therapies for people with schizophrenia and Alzheimer’s disease.
A new model developed by an international team including a University of Guelph researcher will help better understand and manage threatened ecosystems.
Frozen fecal transplantation is just as effective at providing relief to Clostridium difficile (C. diff) patients as fresh microbiota transplantation, according to a new study co-authored by University of Guelph researchers.
A novel therapy tested by University of Guelph scientists for treating a fatal heart disorder in dogs might ultimately help in diagnosing and treating heart disease in humans.
Red squirrels living in a low-stress environment harbour healthier communities of micro-organisms, a result that might hold implications for human health, according to a new University of Guelph -led study.
A new study by University of Guelph researchers that narrows down where and how estrogens affect the brain may help in understanding how the hormones affect cognition and memory in women. The team found that adding the hormone to female mouse brains helps boost short-term learning, likely through a “use-it-or-lose-it” process.
Learning how hagfish survive without oxygen could offer valuable insights for cardiovascular research, according to a new study co-led by a University of Guelph professor. It is the first known study to examine how the isolated hagfish heart functions for extended time periods with little or no oxygen. The results give insight into human cardiovascular health and strategies to protect tissue integrity after cardiac events.
New research explains how the structural properties of coffee beans are altered after being eaten by the civet cat, ultimately producing beans used to make Kopi Luwak coffee, the most expensive coffee in the world.
