Chapter 1: Why do mosquitoes bite some people more than others?
And hello there, Peter Mansbridge here. You're just moments away from the latest episode of The Bridge. It is Wednesday. It is an NBITS day. And we've got lots of interesting stuff for you today. That's coming right up. Hey, a little extra theme music today to start things off. Peter Mansbridge here. Happy Wednesday. Happy hump day.
Chapter 2: What sensory cues attract mosquitoes to humans?
Happy middle of the week day. This is the week where we're going to be eventually crossing over from May to June. You know, just saying it brings a smile on your face, right? I mean, we're getting close to summer and we all look forward to that. We're also getting close to the end of the hockey season, believe it or not. One team now in the finals, the Vegas Golden Knights.
They're there having swept their series with Colorado, and that's certainly surprised a lot of people. Still trying to determine who will win the other series. Will it be Montreal or Carolina? Which brings me to yesterday's program, which seems very popular.
Chapter 3: How does body temperature affect mosquito attraction?
A lot of big audience there for our more butts conversation that dealt a little bit with sports. We were trying to, you know, we were tongue in cheek a lot there about how they were auditioning for the Hockey Night in Canada panel. Now, some of you were concerned about something that happened during that program.
And I'll concede perhaps we poorly phrased a couple of things, being non-sports people like we are. But here's what we were trying to do. This was the premise of the discussion. It's been more than 30 years, 33 or 34 years, since a Canadian-based team won the Stanley Cup. Now, there are a lot of Canadians on all the teams. It's our sport, right?
But there are only the Canadian teams that are based on our side of the border.
Chapter 4: What role does alcohol consumption play in mosquito bites?
And so what we were trying to discuss was that every time a Canadian team reaches the finals, it becomes this sort of Canada's team discussion. We've had it for the Oilers quite a few times, two or three times since Montreal won the Cup in, was it 93? What other Canadian teams have been there? Well, the Canucks were there one year. The Ottawa Senators were there one year.
The Calgary Flames were there one year. Montreal was also there during the COVID years, right?
Yeah.
Who's not on that list of Canadian teams? The Leafs.
Chapter 5: How do blood types influence mosquito preferences?
They never made the finals. They never made the semifinals. Okay, somebody's going to push back on that. Maybe they did one year. I'm not sure. But nevertheless, they've never made the finals in the period of time we're talking about. So that's what our discussion was.
Now, some people took that, and once again, I concede we may well have phrased something poorly, that no Canadian teams have made the finals since the last time they won the Cup. Well, that's not the case, as I just went through the list. Many teams have, but they haven't won the Cup.
Chapter 6: What misconceptions exist about mosquito attraction?
That was the point. And I'm sorry that some people seem to be quite wound up about the way they heard our discussion. Only a few. We've got a lot of letters of people who loved the discussion, loved hearing more and buts in a format and a discussion subject that they're not used to hearing from those two guys. All right, so that puts that aside. You know, let's see what happens.
Let's see what happens when we get to the finals, who's in them and who wins. All right, let's leave it at that. Okay, end bits. You know what end bits are.
Chapter 7: How can you reduce the likelihood of mosquito bites?
They're stories that have popped up in the news that we haven't talked about, but they're interesting. They're interesting subjects. And this first one is definitely an interesting subject for those of us who are getting ready for the summer. It's from a website called phys.org. So P-H-Y-S dot org. And the headline is this, and this is why you'll be interested in it.
Why are some people mosquito magnets? Clues are emerging. So let me read a little bit of this because, you know, We're into mosquito season now, right?
Chapter 8: What are the health implications of sitting too much?
Some areas it's really bad. And it's mosquitoes and black flies, but we're focusing on this discussion about mosquitoes. Ever felt like mosquitoes bite you while ignoring everyone else? Scientists are now making progress in deciphering the complex chemical cocktail that makes particular people more enticing to these disease-spreading bloodsuckers. It's not a misconception.
Mosquitoes are attracted to some people more than others. FrƩdƩric Simard of France's Institute of Research for Development told AFP. But we are not all magnets all the time, the medical entomologist added. A range of sensory cues can cause mosquitoes to pick one human over another. mainly the small and heat our bodies give off and the carbon dioxide we exhale.
Female mosquitoes, which are the only ones that bite. Now, I did not know that. I probably should have known that. I'm seeing a lot of you and hearing a lot of you out there going, come on, you didn't know that? No, I didn't. I didn't know that. Female mosquitoes are the only ones that bite. They detect signals with finely tuned receptors, then choose their target accordingly.
We've known for over 100 years that mosquitoes are attracted by the carbon dioxide that we exhale. This is the first signal that triggers their behavior when they are dozens of meters away, Swedish scientist Richard Ignell told AFP.
Within around 10 meters, mosquitoes will start detecting our odor, and in combination with carbon dioxide, this attracts them even more, said the senior author of a recent study on the subject. As they get closer, body temperature and humidity make particular humans even more enticing. Now, there's a common misconception out there, apparently.
The blood type, your blood type, matters in the choice that mosquitoes make and who to land on and start sucking your blood. The idea that mosquitoes prefer particular blood types has no scientific basis, said one of the researchers. There have been some studies, but only involving very few people, nor is it related to skin, eye, or hair color. Odor, on the other hand, matters greatly.
A soup of molecules produced by our microbiota is more or less appealing to mosquitoes. says another researcher. Humans release between 300 and 1,000 different odorous compounds. Research has shown, but scientists are only just beginning to understand which ones attract mosquitoes.
The researchers released Aedes aegypti mosquitoes, known for spreading yellow fever and dengue, on 42 women in a lab to see which ones they preferred. That must have been a real fun time. We have shown that mosquitoes use a blend of odorous compounds. We identified 27 that the mosquitoes will detect out of the possible 1,000 for their attraction to us.
The woman the mosquitoes most like to bite, which included pregnant women in their second trimester, produced a large amount of a particular compound made by a breakdown of the skin oil, sebum. You know, hold on a minute. Do you believe this? They've got a lab. They've got a lab that's closed off and isolated. They put people in the lab and
