Are you a mosquito magnet? The science behind why some people get more bites

In the battle against bloodsucking mosquitoes, there always seems to be those unfortunate individuals who bear the brunt of the incessant bites while others remain relatively unscathed.

If you are one of the unlucky mosquito magnets, constantly swatting away the pesky insects, you are not alone.  From genetics to body chemistry, experts say many elements come into play that determine who these bloodsuckers find most irresistible.

“They’re flying around looking for a dark object that’s releasing C02 and has heat,” Winnipeg entomologist Taz Stuart, said. “If you’ve been running around a soccer field for an hour, she may think you’re tasty because you’re throwing off lots of C02 and you’re warm.

“That person may be more attractive than a person sitting in the stands, who’s having a beverage and watching the game.”

It is only the female mosquitoes that hunt, and they are picky eaters. If a person’s scent fails to meet their standards, these selective females may find another host to feed on, he said.

When it comes to hunting, female mosquitoes rely heavily on scent in order to detect carbon dioxide emitted by humans, explained David Beresford, an entomology professor at Trent University in Oshawa, Ont.

“They will come to a gas lawn mower or a car exhaust for the same reason,” he said.

“They are following the smell, but it works more like soap bubbles in the air. So they get a big burst of these chemicals and then they track where the smell might be coming from until they get another burst of chemicals.”

And then they try and find more of the order until they see or land on a target, he added.

There are many theories that try to explain why mosquitoes find some people more attractive than others. It could be the heat you give

200 homes or structures damaged, more in danger from devastating Halifax wildfire
devastating wildfire burning near Halifax, which crews are continuing to work on Tuesday.In a statement Monday night, the municipality said a full assessment of the damage cannot yet be confirmed, and the estimated numbers are based on initial visual inspectors by first responders.The municipality said it is currently developing a plan to support affected residents “once detailed mapping is completed.”“It is anticipated that this process will take several days, or maybe longer, as the fires remain active,” it said, adding that representatives from the Insurance Bureau of Canada will be available to speak with affected residents at the evacuation centre at the Canada Games Centre.The blaze broke out Sunday afternoon in the Tantallon area, about a 30-minute drive from downtown Halifax, and has since grown to about 788 hectares. Mandatory evacuation orders are in place in a number of neighbourhoods, impacting more than 16,400 residents.In an update Tuesday morning, Halifax Regional Fire and Emergency Deputy Chief Dave Meldrum said most of the 200 damaged structures were single-family homes, but they also included detached buildings like garages and sheds.“Our thoughts are with the residents affected by this terrible fire,” he said.Meldrum said the fire behaviour Monday night was “stable” due to favourable weather conditions and firefighters were able to make some progress.HRFE has 60 firefighters, six engines, 10 tankers and a number of other ancillary units at the scene, he said.

What Danielle Smith’s Alberta election win means for the rest of Canada
Danielle Smith took the podium Monday night to celebrate her victory in the Alberta election, she had a message for Prime Minister Justin Trudeau.“Hopefully the prime minister and his caucus are watching tonight,” the newly re-elected premier told a raucous crowd of supporters in Calgary.Indeed, all eyes will be on Alberta as Smith begins her second term, which political watchers say will have implications not just for the province but for the rest of Canada as well.Alberta has always had a testy relationship with the federal government and even other provinces as it defends its profitable energy industry and other interests.But the past four years under the United Conservative Party and during the COVID-19 pandemic have seen Edmonton’s relations with Ottawa grow particularly tempestuous.The question now is whether a fresh start is on the horizon — though experts have doubts.“It’s gospel that the federal government ignores Alberta, and to a degree that is correct,” said Allan Tupper, a political science professor at the University of British Columbia who spent decades teaching in Alberta. “There’s a great deal of resentment.”“At the end of the day, (Smith) has to recognize that she has to deal with the federal government.

More Canadian companies adopt ‘stay interviews’ amid push to retain staff
When Tara Vanderloo’s employees are mulling leaving her enterprise software company, she wants to be one of the first people they tell – and to hear their unvarnished reasons why.“I know people get called by recruiters, so I’ve asked the question: ‘who are you talking to or what type of organizations?”’ said the chief experience officer at Sensei Labs in Toronto.“Have you had any thoughts or are you questioning why you want to be here?”Vanderloo poses the questions in one-on-one meetings she and other staff periodically have with the company’s workforce of roughly 70.The discussions, which some companies call “stay interviews,” are designed to collect feedback from employees and are aimed at learning what the company can do to retain valued team members and keep them happy.Some companies have been hosting such meetings for years, but many more adopted the practice over the course of the COVID-19 pandemic as the health crisis caused workers to rethink their careers or seek more flexibility, advancement or support from their employers.Sensei Labs adopted engagement interviews in late 2021, when companies saw millions of people worldwide leave their jobs in what economists and businesses branded “The Great Resignation.”“It was substantial, and it was concerning for us because it’s hard to hire great people and we don’t want to lose them, so the first thing we did is we addressed it head on,” recalled Vanderloo.A companywide meeting was called to discuss the labour market changes afoot, and team leads _ Sensei Labs doesn’t use the term managers _ followed up one-on-one to learn about employee happiness in more detail.Despite a softening job market and suggestions that negotiating power has tipped back in favour of employers,

FILE - (L to R) European Council President Charles Michel, Italys Prime Minister Giorgia Meloni, Canadas Prime Minister Justin Trudeau, Frances President Emmanuel Macron, Japans Prime Minister Fumio Kishida, US President Joe Biden, Germanys Chancello HIROSHIMA, Japan - Leaders of the world’s most powerful democracies vowed Friday to tighten punishments on Russia for its 15-month invasion of Ukraine, days before President Volodymyr Zelenskyy joins the Group of Seven summit in person on Sunday."Our support for Ukraine will not waver," the G7 leaders said in a statement released after closed-door meetings, vowing "to stand together against Russia’s illegal, unjustifiable, and unprovoked war of aggression against Ukraine.""Russia started this war and can end this war," they said.Oleksiy Danilov, secretary of Ukraine’s National Security and Defense Council, confirmed on national television that Zelenskyy would attend the summit."We were sure that our president would be where Ukraine needed him, in any part of the world, to solve the issue of stability of our country," Danilov said Friday. "There will be very important matters decided there, so physical presence is a crucial thing to defend our interests."Zelenskyy on Friday opened a visit to Saudi Arabia, where Arab leaders were holding a separate summit, he announced.Russian President Vladimir Putin’s nuclear threats against Ukraine, along with North Korea's months-long barrage of missile tests and China’s rapidly expanding nuclear arsenal, have resonated with Japan’s push to make nuclear disarmament a major part of the summit.

Trudeau calls out Italy’s LGBTQ+ stance during G7 meeting with Meloni
Justin Trudeau called out the Italian government’s stance on LGBTQ rights during a bilateral meeting with Italian Prime Minister Giorgia Meloni at the G7 Leaders’ Summit in Hiroshima, Japan.“Obviously, Canada is concerned about some of the (positions) that Italy is taking in terms of LGBT rights,” Trudeau told Meloni at the start of the meeting.“But I look forward to talking with you about that.”The comments were made at the start of the meeting, prior to media being ushered out of the room.In March, gay rights activists denounced as homophobic moves by Meloni’s far-right-led government to limit recognition of parental rights to the biological parent only in families with same-sex parents.In a move that would impact hundreds of families, the government told the city of Milan to stop automatically recording both parents in same-sex couples on city registers.It was the last major city to continue the practice that had been briefly adopted in Rome, Turin, Naples and elsewhere after Italy’s high court in 2016 made it easier for gay people to adopt a partner’s biological child.In a readout of the meeting sent out by the Prime Minister’s Office, it says the leaders “exchanged views on the importance of protecting and defending human rights, including the rights of 2SLGBTQI+ people.”“Prime Minister Meloni responded that her government is following court decisions and is not deviating from previous administrations,” the summary said.Trudeau met with Japanese Prime Minister Fumio Kishida earlier in the morning, where both leaders discussed increasing co-operation between G7 countries to further peace and economic prosperity.The G7 Leaders’ Summit is taking place between Friday and Sunday.The summit is expected to focus on

Did WestJet pilots reject $300K+ salaries? Union says figures ‘cherry-picked’
WestJet is telling its pilots it was offering “significant” wage increases that would make them among the highest paid workers in Canada before the pilots’ union issued notice for a strike that could begin this week, Global News has learned.But the union says the “cherry-picked” six-figure salaries included in internal communications do not represent the full scope of the offer they rejected, and criticized the airline for bargaining in public.Global News obtained a memo sent to pilots by John Aaron, WestJet’s vice-president of flight operations, to the airline’s pilots hours after the Air Line Pilots Association (ALPA) issued a 72-hour strike notice Monday evening.WestJet pilots are set to walk off the job at 3 a.m. Eastern on Friday unless a deal is reached.In the memo, Aaron said the airline’s latest offer — which expired after the strike notice was issued — would have raised salaries to “around” $300,000 for a narrowbody aircraft captain and $350,000 for a widebody aircraft captain, before overtime and other stipends.Aaron said those wages would have made narrowbody captains and first officers the highest-paid in Canada.Narrowbody aircraft are the more common passenger planes, like the Boeing 737, that have a single aisle separating passenger seating.
