Researchers in McGill’s Department of Mechanical Engineering and at Drexel University have developed an innovative manufacturing technique that makes female mosquito proboscides, or feeding tubes, into high-resolution 3D-printing nozzles. With its unique geometry, structure and mechanics, the proboscis enables printed line widths as fine as 20 microns, or a little smaller than a white blood cell. This is roughly twice as fine as what commercially available print

A McGill-led study is challenging a popular theory about how dopamine drives movement, a discovery that could shift how scientists think about Parkinson’s disease treatments.
Published in Nature Neuroscience, the research found dopamine does not set the speed or force of each movement, as had been thought. Instead, it appears to act as the underlying support system that makes movement possible.

A new study has linked air pollution exposure and immune-system changes that often precede the onset of autoimmune diseases.
McGill University researchers analyzing Ontario data found that fine particles in air pollution are associated with higher levels of a biomarker linked with autoimmune diseases, such as systemic lupus.

A new international study led by McGill University in collaboration with Jefo Nutrition shows that supplementing dairy cow diets with microencapsulated B-vitamins can significantly reduce greenhouse gas emissions while increasing milk yield and quality. The use of the feed additive cut global warming potential, an internationally standardized measure of climate impact, by up to 18 per cent across seven countries.

McGill University researchers have identified a brain function that helps explain why childhood stress raises metabolic health risks for some women later in life.
A new study found that variations in the brain’s insulin receptor network affect how women respond to early-life adversity. This effect has a lesser impact in men, suggesting there is a sex-specific process at play.

Using proteins from a common tobacco plant virus, McGill chemistry researchers have developed a simple, eco-friendly way to arrange gold nanoparticles into ultrathin sheets, strengthening the particles’ optical properties. The result: cheaper, safer materials for solar panels, sensors and advanced optical devices.

The Kering Foundation, in partnership with McGill University and the Sexual Violence Research Initiative (SVRI), is launching an innovative research program to tackle the often-overlooked links between violence against women and violence against children – a critical global issue with deep social impact.
This multi-year initiative will strengthen evidence-based, locally led research to understand how violence against women and children intersects and to identify effective solutions through programs, services, and interventions.

Women who report high levels of psychosocial stress, such as from caregiving and lack of emotional support, show signs of early heart tissue changes associated with cardiovascular disease – an association not observed in men, a new study reveals.
The results support the notion that there are sex-specific ways in which stress affects cardiovascular health and that risk-assessment processes should take psychosocial factors and mental wellness into account, the researchers said.

A program developed by a McGill researcher to help cancer survivors cope with the fear their cancer will return is expanding across Canada.
The Fear of Recurrence Therapy (FORT) program offers evidence-based support to address what co-founder Christine Maheu calls one of the most overlooked aspects of recovery.

Researchers have cracked one of agriculture’s most complicated genomes, revealing long-hidden DNA rearrangements that could help scientists breed oats that are more resilient, nutritious and sustainable.
The study, by an international consortium that included researchers from McGill University and published in Nature, presents the first-ever “pangenome” and “pantranscriptome” of oats. These map all known oat genes and track how they behave across 33 varieties that grow around the world.

A new study has uncovered promising therapeutic strategies against one of the deadliest forms of prostate cancer.
McGill University researchers at the Rosalind and Morris Goodman Cancer Institute (GCI) identified a mechanism driving neuroendocrine prostate cancer, a rare and highly aggressive subtype for which there currently are no effective treatment options.
