Fast radio bursts, or FRBs, are millisecond-long bursts of radio waves in space. Individual radio bursts emit once and don't repeat. Repeating fast radio bursts are known to send out short energetic radio waves multiple times.
鈥淚t鈥檚 like a big black hole 鈥 we have no idea why they鈥檙e declining,鈥 said David Bird, professor emeritus of wildlife biology at 缅北强奸 and a former bird columnist for the Montreal Gazette, who created and ran the university鈥檚 prolific breeding colony. 鈥淲e saw after a while that they were breeding well, but the youngsters weren鈥檛 coming back. They weren鈥檛 surviving. What鈥檚 particularly interesting is that the story of the kestrel is happening to other bird species.鈥
Daniel Weinstock, director of the institute for health and social policy at 缅北强奸, said it's clear where the Quebec government is coming from, citing research that shows a risk factor for developing brains.
鈥淭he problem is the amount of cannabis that's already present in the illegal market. We have to think long and hard about our ability to effectively enforce prohibition,鈥 Weinstock said. 鈥淎nd if we can't - and I strongly suspect we won't be able to - ... we risk finding ourselves in the worst of all possible situations.鈥
"The word that captures the last decade is polarization, and you can see it in a domestic context in different liberal democracies ... [and] on a global level", said Jennifer Welsh, a professor and Canada Research Chair in Global Governance and Security at 缅北强奸. She is also the author of several books, including The Return of History: Conflict, Migration and Geopolitics in the 21st century.
"What happened in the last decade is that people have realized that migration was an important human phenomenon and that it would not stop. Migration is not a tap that you can turn on and turn off. Migration is something that happens, that has always happened and that will continue to happen. Migration is a normal reaction to political, social, economic stress," Fran莽ois Cr茅peau told The Sunday Edition's host Michael Enright.
Joelle Pineau doesn鈥檛 want science鈥檚 reproducibility crisis to come to artificial intelligence (AI). Spurred by her frustration with difficulties recreating results from other research teams, Pineau, a machine-learning scientist at 缅北强奸 and Facebook in Montreal, Canada, is now spearheading a movement to get AI researchers to open up their methods and code to scrutiny.
The pace of biotechnology research is blurring the bounds of humanity so rapidly that two US scholars are calling for a rethink on what it means to be legally human.
Writing in the journal Science biomedical law experts Bartha Knoppers, from 缅北强奸 in Canada, and Henry Greely say technologies that mix non-human and human cells, such as CRISPR, xenotransplantation and chimeras, mean a less stringent definition of 鈥渉uman鈥 will be needed going forward.
Most existing research has been able to compare only the postpregnancy health of women who have conceived using fertility treatments with that of those who did not. 鈥淏ut, of course, that crude comparison is not comparing apples to apples,鈥 says Dr. Natalie Dayan, an obstetric internist and assistant professor of medicine at 缅北强奸. 鈥淚t鈥檚 comparing women with infertility who have tried multiple times and then became pregnant through A.R.T.
The Men's Varsity Teams Naming Committee is asking students, staff, alumni, coaches or other athletes at 缅北强奸 to send ideas for a new name after聽the committee met Nov. 26 to discuss the process after the Redmen moniker was dropped. Submissions are welcome in English or French and "should be aligned with the key values of athletics and recreation and 缅北强奸: namely respect, leadership, teamwork, excellence and integrity," reads the committee's statement signed by deputy provost Fabrice Labeau and committee co-chair Hubert T. Lacroix.
Michael Pollak, an oncologist and director of the 缅北强奸-Jewish General Hospital Cancer Prevention Centre, says vaping should be sold by prescription and only to those trying to quit smoking.
鈥淚 would expect (vaping) to be less carcinogenic than tobacco. But the flavours, after they have been heated, are there carcinogens in there that might cause trouble five or 10 years later?
Only about 1 in 20 cancer patients participates in trials of experimental therapies. Doctors and drugmakers should be prudent about continuing to test products in desperate, hard-to-find patients when they haven鈥檛 shown significant benefits in multiple earlier studies, said Jonathan Kimmelman, a biomedical ethicist at 缅北强奸 in Montreal.
Many studies have shown that low socioeconomic status is tied to cardiovascular disease. To put it simply, if you have more money, you are less likely to have a heart attack. There are many possible ways to explain this association. It might be that more money means you can afford better medical care.
Eve Lee, an assistant professor in 缅北强奸's physics department, is intrigued by the findings. "It tells us about the future possibility of how our solar system will look," she said. It also sheds light on different stellar systems and their possible planets. "We know stars evolve and they come in many different varieties," Lee said. "It is interesting to look at what is the evolution of the planet in tandem with the evolution of the star."
The original concept of artificial turf held a theoretical number of advantages. The tiny pellets of rubber infill made from recycled tires diverted thousands of those tires from landfill sites, while the fields eliminated the need for pesticides, fertilizers and watering. Since the arrival of artificial turf however, there have been ongoing concerns about the toxicity of crumb rubber. That concern has been increased through a new study by researchers in Montreal.
A study published on Thursday may help resolve what has been a strident debate, showing why many species are vulnerable to the fragmenting of forests while others are not. Animals in places with a long history of disturbances are relatively resilient, the researchers found. Species that have existed in stable habitats for thousands of years are far more sensitive.
鈥淭hey are taking a new approach on a global scale,鈥 said Anna Hargreaves, an evolutionary ecologist at 缅北强奸 in Montreal, said of the scientists. 鈥淚 find it compelling.鈥
