The world’s oldest algae fossils are a billion years old, according to a new analysis by earth scientists at 㽶Ƶ. Based on this finding, the researchers also estimate that the basis for photosynthesis in today’s plants was set in place 1.25 billion years ago.
New research has drawn a link between changes in the brain’s anatomy and biomarkers that are known to appear at the earliest stages of Alzheimer’s disease (AD), findings that could one day provide a sensitive but non-invasive test for AD before cognitive symptoms appear.
Scientists have known for some time that one of the first signs of AD is buildup of amyloid-Beta and tau proteins in the brain. They have also known that the hippocampus atrophies and loses volume in some AD patients years before cognitive decline.
㽶Ƶ researchers have chemically imprinted polymer particles with DNA strands – a technique that could lead to new materials for applications ranging from biomedicine to the promising field of “soft robotics.”
In a study published in Nature Chemistry, the researchers describe a method to create asymmetrical polymer particles that bind together in a spatially defined manner, the way that atoms come together to make molecules.
Believe it or not, a tropical blood parasite native to Latin America could be harmful to Canadians. Infectious diseases like malaria or Zika may have dominated recent headlines but Chagas – the “Kissing Bug” disease – is in the spotlight following the publication of a new case study in the Canadian Medical Association Journal (CMAJ). Tropical and laboratory medicine experts from Winnipeg and Montreal warn natives of specific Central and South American nations and their offspring are at risk of contracting Chagas disease - even after they have moved to Canada.
How individual police forces treat those that they suspect of being illegal immigrants varies greatly from one city to the next in the U.S. In Albuquerque, New Mexico, the police department has a policy that states clearly, “Officers shall not stop, question, detain or arrest any person on the ground that they may be undocumented and deportable foreign nationals.” But this is unusual. Local police departments across the U.S. have become increasingly involved in enforcing federal immigration laws since the mid-1990s.
One of the world’s 7,000 languages vanishes every other week, and half – including scores of indigenous North American languages -- might not survive the 21st century, experts say. To preserve as much linguistic diversity as possible in the face of this threat, 㽶Ƶ scientists are proposing to borrow a leaf from conservation biology.
A study published in the Proceedings of the National Academy of Sciences has shown that musical training helps people hear speech syllables in loud environments, and has shown how this happens. Using functional magnetic resonance imaging (fMRI), researchers Yi Du and Robert Zatorre monitored brain function as musicians and non-musicians listened to speech fragments and varying background noise levels.
A clinical trial almost ten years in the making has revealed that risky, but powerful, clot busting drugs and medical devices do not improve outcomes for patients experiencing deep vein thrombosis (DVT), nor do they prevent the development of post-thrombotic syndrome (PTS) when compared with conventional blood thinning medications. The results of the Acute Venous Thrombosis: Thrombus Removal with Adjunctive Catheter-Directed Thrombolysis (ATTRACT) study are published in the New England Journal of Medicine.

For the past ten years, the International Centre for Youth Gambling Problems and High-Risk Behaviors at 㽶Ƶ and the National Council on Problem Gambling (NCPG) in Washington, D.C. have come together for the annual Holiday Lottery Campaign, a corporate social responsibility program designed to help lotteries make adults aware of the risks of giving lottery products as holiday gifts to minors.
Industry and academia team up for the benefit of people suffering from ALS
A unique industry-academia partnership will increase the rate at which promising drug compounds can be tested as potential treatments for amyotrophic lateral sclerosis (ALS), a disease with no known cure that affects 200,000 people worldwide.
The partnership between The Montreal Neurological Institute and Hospital (MNI) and Takeda Pharmaceutical Company Limited (Takeda) will allow compounds developed by Takeda scientists to be tested on cell lines produced at the MNI.
Fatty liver is among the most frequent causes of liver disease in Canada and in Western countries and is one of the main indications for liver transplant. For some time, researchers have suspected that people living with HIV could be at higher risk of developing liver disease, which,as a result of longer life expectancy thanks to antiretroviral therapy, has become the major cause of their mortality in North America.
To celebrate Montreal’s 375th anniversary, the Centre for Interdisciplinary Research on Montreal wanted to examine the mechanisms and processes that have made it possible, in the history of the city, to maintain a relative social peace. The CIRM is now proud to present its first publication (in French),Vivre ensemble à Montréal. Épreuves et convivialités.
