Decrease in relapses of Crohn's disease in youth
Decrease in relapses of Crohn’s disease in youth
Despite an increase in new diagnoses, a decrease in relapses of Crohn's disease was observed in children and adolescents. A research team led by Dr. Prévost Jantchou, clinician and researcher at the CHU Sainte-Justine Research Centre, focused on the rate of Crohn's disease relapse, as well as factors associated with relapse, in children over the past decade.

Increasing harassment of researchers subject of new report
Increasing harassment of researchers subject of new report
A Canadian task force made up of university-based researchers, including at Western, is tackling the growing number of online threats and harassments researchers face and has called on the federal government to initiate a nationwide, coordinated approach to addressing the issue. "The problem has always been there, but the tools have changed," said Howard Ramos, chair of the department of sociology, and co-author of a Royal Society of Canada briefing, " Protecting Expert Advice for the Public: Promoting Safety and Improved Communications.

RNA map of cell nucleus reveals new insights into gene regulation and cell division
RNA map of cell nucleus reveals new insights into gene regulation and cell division
Most people are familiar with the cell nucleus from grade school biology as a storage compartment for DNA. But the nucleus also contains several distinct structures called nuclear bodies or domains - and some of them are brimming with genes' messages, also known as RNA transcripts. Scientists are just now beginning to understand these structures, with University of Toronto researchers recently reporting the first large-scale survey of RNA transcripts that are associated with different nuclear bodies in human cells.

Urbanization is driving the evolution of plants around the world, University of Toronto study finds
Humans are constantly re-shaping the environment by building sprawling cities, but a new study demonstrates that urban environments are also altering the way life itself evolves - and it's happening all around the world. Researchers, led by evolutionary biologists at the University of Toronto Mississauga, analyzed data about the white clover plant that was collected by 287 scientists in 160 cities across 26 countries, from Toronto and Tokyo to Melbourne and Munich.

LSD, a future anti-anxiety pill?
LSD, a future anti-anxiety pill?
The craze for psychedelics used for therapeutic purposes is real. However, the scientific evidence supporting their effectiveness and explaining their mode of action in treating mental health disorders is still very thin. A new study led by Dr. Gabriella Gobbi, a senior scientist in the Brain Repair and Integrative Neuroscience (BRaIN) Program at the Research Institute of the McGill University Health Centre (RI-MUHC), sheds light on previously unexplained neurobiological mechanisms by which LSD is believed to relieve anxiety.

Stemming the tide of invasive species
Stemming the tide of invasive species
Ballast water release from ocean vessels has introduced hundreds of invasive species to coastal ecosystems worldwide, causing major disruptions to fisheries and biodiversity. Attempts to control aquatic invasions have met with mixed success in general. However, a new study suggests that a bi-national regulation targeting ships entering the Great Lakes since the mid-2000s has been remarkably effective in reducing a large proportion of the invasive species in the world's largest freshwater ecosystem .

Low COVID vaccine uptake linked to housing insecurity
Low COVID vaccine uptake linked to housing insecurity
By the end of September 2021, uptake of COVID-19 vaccines among adults with a recent experience of housing insecurity were 25 per cent lower than the adult population of Ontario for a first dose, and 34 per cent lower for a second dose, according to a new study. Published in The Lancet Public Health , the study is the first in Canada to examine vaccination rates among persons experiencing homelessness.

Challenges with a novel approach to managing overweight and obesity
Challenges with a novel approach to managing overweight and obesity
Managing overweight and obesity is challenging, and a new randomized controlled trial found that, contrary to earlier evidence, making small changes to caloric intake and physical activity levels did not prevent long-term weight gain better than monitoring alone. The research is published in Canadian Medical Association Journal (CMAJ).

Computer drug simulations offer warning about promising diabetes and cancer treatment
Metformin highly effective in targeting diabetes and some cancers but potentially dangerous with others By Using computer drug simulations, researchers have found that doctors need to be wary of prescribing a particular  treatment  for all types of cancer and patients. The drug, called metformin, has traditionally been prescribed for diabetes but has been used in clinical settings as a cancer treatment in recent years.
