What wiped out the dinosaurs? A meteorite plummeting to Earth is only part of the story, a new study suggests. Climate change triggered by massive volcanic eruptions may have ultimately set the stage for the dinosaur extinction, challenging the traditional narrative that a meteorite alone delivered the final blow to the ancient giants.
McGill biology researchers found that there are patterns regarding the importance of temperature in determining where species live, shedding light on their sensitivity to climate change
Scientists have found that while eye-to-eye contact is rare, it plays a vital role in conveying important social messages and predicting subsequent social behavior.
Both elegant and fierce, killer whales are some of the oceans’ top predators, but even they can be exposed to environmental pollution.
As the planet gets hotter, the need for cool living environments is becoming more urgent. But air conditioning is a major contributor to global warming since units use potent greenhouse gases and lots of energy.
Sunscreen is important, says Dr. Ivan Litvinov, but it is also the least effective way to protect your skin when compared to sun protective clothing and sun avoidance

Sixty per cent of roughly 1,600 Canadians who took part in a new McGill University study say their lifestyle habits either stayed the same or improved during the COVID-19 pandemic.
Scientists have been worried about the potential harms of microplastics for years. These small plastic particles less than 5 mm in length have been found everywhere because of plastic pollution – from the Earth’s deep oceans to remote regions in Antarctica, and even the seafood we eat.
Astronomers from McGill University are part of an international team that has discovered 25 new sources of repeating fast radio bursts (FRBs), these explosions in the sky that come from far beyond the Milky Way.
Nurses exposed to 40 minutes of bright light before their night shifts feel less fatigued and make fewer errors at work, according to a study led by McGill University. The nurses also slept better after their shifts.
Killer whales (also known as orcas) are intelligent predators. While it’s known that killer whales in the Pacific Northwest exploit widely different food types, even within the same region, we know much less about the feeding habits of those found throughout the North Atlantic.
Depression is widely reported to be more common in women than in men, with women twice as likely to receive a diagnosis than men.
Wetlands are among the most threatened ecosystems in the world. A new study, published in Nature, has found that the loss of wetland areas around the globe since 1700 has likely been overestimated.
Snakes and mice don’t look alike. But much of what we know about skin coloration and patterning in vertebrates generally, including in snakes, is based on lab mice.
A new study led by scientists at The Neuro (Montreal Neurological Institute-Hospital) of McGill University finds a correlation between neurodegeneration in obese people and Alzheimer’s disease (AD) patients, suggesting that losing excess weight could slow cognitive decline in aging and lower risk for AD.
About a quarter of the world’s electricity currently comes from power plants fired by natural gas. These contribute significantly to global greenhouse gas emissions (amounting to 10% of energy-related emissions according to the most recent figures from 2017) and climate change.
The brain is a complex organ, and no one imaging mode can catch everything that’s going on inside it. Over the years, multiple “brain maps” have emerged, each focusing on different brain processes, from metabolism to cognitive function.
A national survey of close to 1000 adults in Greenland (where approximately 90% of the population is Indigenous) conducted by a McGill University-led research team has found that a surprisingly large majority – 3 out of 4 Greenlanders – support extracting and exporting sand left by the melting ice sheet.
For the generations who grew up watching Finding Nemo, it might not come as a surprise that the North American West Coast has its own version of the underwater ocean highway – the California Current marine ecosystem (CCME).
Each mistletoe berry can produce up to two metres of a gluey thread called viscin. It allows the seeds of this parasitic plant to stick to and infect host plants.
Air pollution kills approximately 7 million people every year worldwide.
A new study from McGill University finds higher incidence of lung cancer and brain tumors in people exposed to wildfires.
Imagine being in a place where the winds are so strong that they move at the speed of sound.
The COVID-19 pandemic has tested our psychological limits. Some have been more affected than others by the stress of potential illness and the confusion of constantly changing health information and new restrictions.
Surprising as it sounds, all life forms in the ocean, from small krill to large tuna, seem to obey a simple mathematical law that links an organism’s abundance to its body size.
Type 1 diabetes, rheumatoid arthritis, and cancer are just some of the disorders associated with specific genes not “turning on” and “turning off” as they should.
A new study shows that artificial intelligence networks based on human brain connectivity can perform cognitive tasks efficiently.
The Arctic is warming at approximately twice the global rate. A new study led by researchers from McGill University finds that cold-adapted Arctic species, like the thick-billed murre, are especially vulnerable to heat stress caused by climate change.
Climate change is exacerbating problems like habitat loss and temperatures swings that have already pushed many animal species to the brink.
Every high-school physics student learns that sound and light travel at very different speeds.
Since fast radio bursts (FRBs) were first discovered over a decade ago, scientists have puzzled over what could be generating these intense flashes of radio waves from outside of our galaxy.
Researchers at the Lady Davis Institute (LDI) at the Jewish General Hospital have discovered that increased levels of the protein OAS1 are associated with reduced mortality and less severe disease requiring ventilation among patients with COVID-19.
It's known that the primary cause of the mass extinction of dinosaurs, about 66 million years ago, was a meteorite impact.
This holiday season will be a lonely one for many people as social distancing due to COVID-19 continues, and it is important to understand how isolation affects our health.
Trust in public institutions is linked to fewer COVID-19 deaths, but trust and belonging to groups is associated with more deaths, according to a wide-ranging, McGill-led study of 30-day COVID-19 mortality rates in 84 countries. Greater economic inequality is also associated with COVID-19 mortality.
In response to the COVID-19 pandemic, public transport agencies across North America have made significant adjustments to services, including cutting trip frequency in many areas while increasing it in others.
