M87* One Year Later: Proof of a persistent black hole shadow

Fri, 01/19/2024 - 10:49

The Event Horizon Telescope (EHT) Collaboration, including Professor Daryl Haggard at McGill University, has released new images of M87*, the supermassive black hole at the center of the galaxy Messier 87, using data from observations taken in April 2018. With the participation of the newly commissioned Greenland Telescope and a dramatically improved recording rate across the array, the 2018 observations give us a view of the source independent from the first observations in 2017.

What Zebra mussels can teach us about combatting invasive species, developing sustainable materials

Wed, 01/17/2024 - 15:04

A recent study from researchers in Canada and Germany has revealed that an unlikely event, occurring over 12 million years ago played an important role in shaping one of Canada’s most damaging invasive species. Zebra and quagga mussels, belonging to the Dreissenid family, are widespread freshwater invasive species throughout North America that present a significant danger to native ecosystems by competing for resources. Using a fibrous anchor called a byssus, Dreissenid mussels contribute to biofouling on surfaces and obstruct intake structures in power stations and water treatment plants.

Every year an estimated 20 million babies worldwide are born with low birth weight, according to the World Health Organization, leading to a wide range of significant short- and long-term consequences. And though you may think the obvious answer is greater emphasis on food and nutrition for pregnant women, leading McGill University researchers are proposing an unexpected solution: the cellphone.

Discovery unravels the mystery of a rare bone disease

Tue, 01/16/2024 - 10:46

A McGill-led team of researchers have made an important discovery shedding light on the genetic basis of a rare skeletal disorder. The study, published in Nature Communications, reveals that a defect in a specific gene (heterozygous variants in the matrix Gla protein, or MGP) may cause a disorder that affects the structure of connective tissues that supports the body.
