SuperNOVA summer camp: High school students get hands-on experience solving climate problems
High school students in Dalhousie University's SuperNOVA Ocean Climate Innovation Program put their remotely operated vehicles to the test in the Halifax Harbour. Jarman Ley, the program coordinator of SuperNOVA, said 25 students took part in the program focused on ocean technologies, engineering, and artificial intelligence. 'We started this program to get high school students excited and interested in the climate and how the ocean relates to that,' said Ley. 'They all developed programs for their own sensors and then drove them into the harbour to see the difference between historical harbour data and current harbour data.'

'They are specifically doing dissolved oxygen to see if fish have enough oxygen to breathe. They are doing the solidity because as climate changes or temperature changes you can have saltier waters, which is inhospitable to plants. They are doing the acidity of the water, the oxygen reduction potential, which is essentially how the ocean cleans itself.' Ley said the program teaches skills the students can take into their university careers. 'It's been a really interesting way to take all of the knowledge that we've learned and wrap it into one project that we can test and see the results of,' said student Finnegan Jafmann.

(Paul DeWitt/CTV Atlantic) 'A lot of the people here are probably going to use this as really good experience because we got to go to a lot of places. We got to tour multiple parts of the Dal building and the engineering section, and we got to talk to a lot of people about their projects,' said student Emily Whidden. 'For me, it was a lot of interesting information, but for the people who are planning to go into these fields or even come to Dal, it was probably a really good foot in the door.' From 2023 to date, Dalhousie University said SuperNOVA has reached more than 27,500 youth through this not-for-profit initiative. 'Young people are the lifeblood of the future. So, we really believe if we start to encourage them now, that they'll be that much more advanced when they get to university and potentially study it and develop the next generation of innovation,' said Ley. According to Dalhousie University, SuperNOVA summer camps introduce participants to STEM concepts, careers and mentors through 'fun experiments and innovative hands-on activities.'

Here's why teens don't belong on dating apps
Nearly one-in-four teens ages 13 through 18 have used dating apps, according to the Journal of Psychopathology and Clinical Science. (Julio Lopez/Pexels) Teenagers are using dating apps more than we previously knew, according to research published this week in the Journal of Psychopathology and Clinical Science. The study found that 23.5 per cent of teens ages 13 through 18 used dating apps over a six-month period, which is more than past estimates. The study is believed to be the first to track how teens use dating apps by recording their keyboard activity rather than relying on self-reports, according to the researchers. The study found that teens who used dating apps didn't generally have more symptoms of mental health challenges after six months than those who didn't. However, those who used dating apps frequently were more likely to have symptoms of major depressive disorders. 'This study showed some support for dating app users having greater depressive symptoms and greater engagement in risky behaviors,' said Lilian Li, a postdoctoral fellow in the department of psychiatry and behavioral sciences at Northwestern University's Feinberg School of Medicine in Chicago and the study's lead author. It's unclear whether that's because the dating app users were harmed on the apps through things such as exposure to harassment or risky behaviors, Li said, or whether those who were depressed used dating apps because they had trouble connecting with others. Li cautioned that the study was small — it included 149 teens in the United States, 35 of whom used dating apps. And because it only tracked keyboard entries, it wasn't able to measure things such as lurking or liking and disliking profiles. There's still reason for parents to be concerned, because dating apps could also be harming kids in other ways. That's why, when I speak to parents and students about how to handle kids' use of apps, I suggest that teenagers not use online dating platforms at all. Teens can connect with predators online One reason I don't think teens belong on dating apps is because they're dangerous. Researchers have warned that registered sex offenders freely use online dating sites. Online dating particularly raises the risk of teens being catfished, manipulated into an emotional relationship with someone using an assumed identity. That creates the opportunity for the other person to convince the teen to share an intimate image, which can then be used for financial extortion or to pressure the victim into further exploitation. Wolf Image The dating app Tinder logo (Aamir Qureshi/AFP/Photographer: Aamir Qureshi/AFP/) These risks make dating apps dangerous for adults but even more so for teenagers, because the teenage brain is wired to accept greater risks in the pursuit of rewards, according to the UCLA Center for the Developing Adolescent. That's why it didn't surprise me that the new research found that teens who engaged in other risky behaviors, such as using substances and breaking rules, were more likely to use dating apps. We can't expect teenagers to consider that the person they think is their new boyfriend or girlfriend might actually be an adult cybercriminal. Teens also can't be expected to think through the potential consequences if they decide to meet up in person with someone they connected with online. 'Minors are not permitted on our dating apps, full stop,' said a spokesperson for the Match Group, which owns Tinder, the most-used dating app among teens in the study. 'Our platforms are for adults 18 and older, and we deploy industry-leading technology and human oversight to keep underage users off them. Our brands deploy sophisticated safety tools including AI-powered age verification, ID verification, and device blocking, as well as human moderators to proactively detect and remove minors and bad actors. 'We work with longstanding partners like THORN to enhance safety measures and, this year, supported the founding of ROOST, a nonprofit focused on building scalable tools for child safety. We continue to invest in cutting-edge tools, technology, and partnerships to help ensure our platforms remain safe for the communities we serve.' The spokesperson also noted that the Match Group offers a safety tool to conduct background checks on users and that the statistics in the new research include social discovery apps, which are different from dating apps. Dating apps don't teach teens to have healthy relationships The problem is not just that dating apps are dangerous, which they can be. They can also send the wrong signals to young people about human relationships. If you want to establish and maintain a relationship with someone in person, you generally have to learn things like how to have a two-way conversation, show consideration for the other person and even resolve disagreements that might come up. Grindr A phone screen shows multiple apps, including Grindr, a dating app for gay men. These are all skills that teens need to practice and which will serve them well in many aspects of their lives. They'll not only help youth deal with people such as future professors and employers but will likely make them happier over the long run. Close relationships are even more important for our happiness than things such as money or fame and are also important to our health, Harvard University researchers found in one of the longest studies of adults ever conducted. In interviews for my book, people told me they felt dating app users invest less in the relationships they form with their 'matches' because the apps convey the impression that there are always more people available to swipe on. 'If someone upsets you for the smallest reason, you can go to a dating app and find someone else,' one woman told me. So teens are learning they can walk away from dating apps feeling like romantic partners are easily obtained and let go, rather than learning to refine skills to maintain close offline relationships. There are other ways to meet their needs To start conversations about these concerns, parents should check in with teens on whether they're using or want to use dating apps. If teens say yes, it's an opportunity to consider how they can meet their needs in other ways. For example, if teens are lonely or want to find a romantic partner, one of the best things we can do is let them get together with peers in person. They can connect with friends and even potential romantic partners who share similar interests by signing up for extracurricular activities. It is also an important way of helping teens feel like they matter, which is one of the best means for promoting well-being. The new study found that dating apps may give teens who are sexual and gender minorities in their communities ways of making valuable social connections. It would be even better, however, for parents to explore how such teens can make those connections by meeting up with the kinds of people they want to know face-to-face. Some teens may also want to use dating apps because some platforms have suggested they have algorithms that can match people with their soulmates — or at least compatible romantic partners. However, decades of research tells us this isn't possible, because it turns out that people's personality traits don't actually predict whether they'll do well as a couple. Prepare teens for using dating apps in the future Still, 30 per cent of Americans have used a dating app or site at some point, according to a 2023 Pew Research Center survey, so it's possible that your teen will find a way to evade your rules against using them now or will use one in the future. That's why you should talk to teens about how to stay safe on dating apps if they do use them at any point in their lives. I recommend video chatting with people before meeting up in person to confirm that they appear to be who they say they are, meeting in public places, telling loved ones where you're meeting, telling the person you're meeting that your loved ones know where you are, and not being alone with someone until you're confident you can trust them. I know parents think their children would never use a dating app or go meet a stranger they only know online. But since this new research suggests teens are using these apps more than parents may realize, it's best to be prepared. Whether teens are just breaking your rules or getting into trouble online, they are missing out on learning to establish healthy relationships face-to-face. That's why parents should talk to teens now about these concerns, helping them get their dating lives started on the right track instead of merely swiping right.

Destined to be a boy mom? New study suggests baby's sex isn't always random
Ashley Clouthier says she hoped her first child would be a boy, so when he was, she was ecstatic. Clouthier, 39, of Almonte, Ont., grew up with an older brother, and wanted the same experience for the large family she was planning with her husband. And when their next child was also a boy, well, even better. Best buds close in age, she thought, and two big brothers for their brood of future children. But then their third child was a boy. And their fourth. Today, Clouthier's boys are ages 13, 12, 10 and four — and she says she's not planning to have any more children. But if she did? "I'm sure it would be a boy," she said with a laugh. There just might be some truth to that, according to a new study that suggests a child's sex at birth might not be entirely random. The study, published July 18 in the journal Science Advances, examined the maternal and genetic factors that influence the sex of offspring after several of the co-authors observed examples of friends, colleagues and family members who had produced either all boys or all girls, which, they say, raised questions about chance. Researchers at the Harvard T.H. Chan School of Public Health examined a dataset of 58,007 U.S. women with two or more singleton live births and found that "each family may have a unique probability of male or female births," they wrote in the study. "The data suggested that there may be families that are more likely than not to have only girls, [and] families that are more likely than not to have only boys," Dr. Jorge Chavarro, a professor of nutrition and epidemiology and one of the authors of the study, told CBC News. 'A weighted coin' Specifically, mothers with three or more children were more likely to have either all boys or all girls, which challenges the traditional view that the probability is "random and independent," or that you have a 50-50 chance of having a boy or a girl each pregnancy, the authors wrote. They calculated that, in families with three boys, the probability of having another boy was 61 per cent, and in families with three girls, the probability of having another girl was 58 per cent. "Akin to flipping a weighted coin with roughly a 60-40 probability," Chavarro explained. The study suggests that there are subtle biological or genetic influences at play, rather than pure chance, which is what we know to be true of most things in life, said Dr. Sebastian Hobson, the head of labour and delivery at Mount Sinai hospital in Toronto and a maternal fetal medicine specialist. Hobson, who is also the chair of obstetrics for the Society of Obstetricians and Gynaecologists of Canada and who was not involved in the study, noted that the Harvard study is large and methodologically rigorous, but as with any study, the results should be interpreted with caution. The observed effects are small, he said, don't determine cause and effect, and the large population was predominantly white and U.S.-based, so can't be generalized globally. They also didn't gather any information about the biological fathers, he added. "Biology can nudge these probabilities slightly, but predicting a child's sex remains highly uncertain," Hobson said. "I think this is a great study, but it's not the be all and end all of sex determination." WATCH | Is gentle parenting too rough on parents? Why more parents are ditching the gentle approach 5 months ago 'Lose the birth lottery' Previous studies have found that parents are more likely to have a third child if their first two are the same sex, often in hopes the third child will be the opposite. And you only have to spend some time at school pickups, playgrounds and community pools to see that, well, it doesn't always work out that way. One recent study in the Journal of Behavioral and Experimental Economics refers to those who have three boys or three girls as parents who "lose the birth lottery." "If I got paid $1 for every time someone said, 'Are you going to try for a girl?' I'd be a millionaire," said Krystyna Recoskie, 48, also of Almonte, Ont., and a friend of Clouthier's. She has three boys, ages 15, 13 and 11. "For a while, it made me feel like I had failed. Like it was bad. How ridiculous is that?" she added. "I am blessed. I am complete." In the Harvard study, the researchers found that two-child families were actually more likely to be opposite sexes, or boy-girl, which they suggested implies that "couples are more inclined to stop reproducing when a balanced sex was reached." As for why some mothers were more likely to give birth to all-boys or all-girls, the authors suggested some women are at high risk of producing offspring of a specific sex due to factors affecting sperm survival. As well, procreation behaviour can be strongly influenced by the sex of previous children, they added. In addition, the authors found that older maternal age at first birth could be a risk factor for repeatedly giving birth to children of only one sex. This may be due to biological changes in the body, they said, like shorter follicular phase and lower vaginal pH. 'Four boys, poor you' Other studies have explored the idea of gender disappointment, or the feeling of sadness a parent may experience when their child's sex doesn't match with what they'd hoped for, and suggest it's more prevalent than we may think. "Gender disappointment in Western cultures is mostly related to the desire for 'gender balance' in the family — having a child of each gender to experience being a mother to sons as well as daughters," notes a 2023 study in the BJPsych Bulletin journal. Clouthier says she's never been disappointed about having four boys, and any negativity she experiences comes from other people. In a lot of ways, it's easier to have four kids all the same sex, she explained, between the hand-me-downs and gear they already have on hand. Birthday party themes can also overlap. And yes, it can get loud, and rough, and there are kid-sized holes in the drywall, but she notes her boys are also sweet, sensitive and cuddly. "I still get comments all time time, where people say, 'Four boys, poor you,'" Clouthier said. And I'll say, 'Yeah, lucky me!'"
