Three-person DNA IVF stops inherited disease—eight healthy babies born in UK first

Teen Health 2 - Fri, 2025-07-18 08:05
In a groundbreaking UK first, eight healthy babies have been born using an IVF technique that includes DNA from three people—two parents and a female donor. The process, known as pronuclear transfer, was designed to prevent the inheritance of devastating mitochondrial diseases passed down through the mother’s DNA. The early results are highly promising: all the babies are developing normally, and the disease-causing mutations are undetectable or present at levels too low to cause harm. For families once haunted by genetic risk, this science offers more than treatment—it offers transformation.

Sweet but risky: Common sweeteners may be accelerating puberty in kids

Teen Health 2 - Tue, 2025-07-15 00:16
Kids who consume artificial and natural sweeteners like aspartame, sucralose, and glycyrrhizin may face an increased risk of early puberty, especially if they carry specific genetic markers. This large-scale Taiwanese study links sweeteners to hormonal changes and gut bacteria imbalances that can speed up puberty, with effects differing between boys and girls. Early onset puberty has been tied to serious health consequences later in life, including emotional stress and metabolic disorders. The findings could reshape dietary recommendations and encourage genetic screening to mitigate long-term risks.

Teens Still Hustling for Summer Jobs, Even as Hiring Slows Down

Teen Health & Wellness - Mon, 2025-07-07 07:11
Summer jobs are harder to land this year, with fewer openings at places like restaurants, stores, and amusement parks. But teens across the country aren’t giving up. Many have been applying early and often, determined to earn money and gain real-world experience.

Even with challenges like competition from adults and more selective hiring, teens are getting creative—handing out résumés in person, picking up babysitting gigs, or joining programs like the Boys & Girls Clubs to boost their job skills. The job market may be cooling, but teen motivation is heating up.

Pregnancy’s 100-million-year secret: Inside the placenta’s evolutionary power play

Teen Health 2 - Sun, 2025-07-06 05:22
A group of scientists studying pregnancy across six different mammals—from humans to marsupials—uncovered how certain cells at the mother-baby boundary have been working together for over 100 million years. By mapping gene activity in these cells, they found that pregnancy isn’t just a battle between mother and fetus, but often a carefully coordinated partnership. These ancient cell interactions, including hormone production and nutrient sharing, evolved to support longer, more complex pregnancies and may help explain why human pregnancy works the way it does today.

Researchers tested 200 toddlers — 96 chemicals were lurking in their bodies

Teen Health 2 - Tue, 2025-07-01 22:54
Researchers testing urine from 2- to 4-year-olds in four U.S. states uncovered 96 different chemicals, many of them unmonitored and linked to hormone and brain disruption. Legacy toxins like triclosan are slowly declining, yet replacements such as DINCH plasticizer and modern pesticides are rising. Toddlers—especially the youngest, later-born, and those from minority groups—often carried higher levels than their own mothers. Scientists urge expanded biomonitoring and stricter regulations before these invisible pollutants derail early development.

Synthetic storm: What’s really in your teen’s vape — and why scientists are alarmed

Teen Health 2 - Tue, 2025-07-01 09:00
Teen vaping is changing fast — and not in a good way. A large national study found that more adolescents are vaping THC, CBD, and especially synthetic cannabinoids, which are often unregulated and far more dangerous. Even more troubling, many teens don’t know what’s in their vape pens at all. Researchers also found that girls are now more likely than boys to vape these substances. As these mysterious and risky chemicals gain popularity, scientists are sounding the alarm about the urgent need for better education, regulation, and awareness.

Summer Heat Warning: Protect Yourself from Heat Illness

Teen Health & Wellness - Mon, 2025-06-23 07:10
With summer temperatures rising, health officials are reminding everyone to take precautions against heat-related illness. High heat and humidity make it harder for the body to cool itself, increasing the risk of heat exhaustion or heat stroke. Teens, athletes, young children, and people with health conditions are especially at risk.

To stay safe, drink plenty of water, wear lightweight clothing, and avoid outdoor activity during peak heat hours (10 a.m. to 4 p.m.). Spend time in air-conditioned places when possible, and never leave people or pets in parked cars. Staying informed and prepared can prevent serious health problems.

More Teens Are Choosing Alternatives to College

Teen Health & Wellness - Mon, 2025-06-09 07:04
A growing number of teens are rethinking the traditional college path. According to a new survey from American Student Assistance, only 45 percent of students in grades 7–12 expect to attend a two- or four-year college, down from 73 percent in 2018. Meanwhile, interest in nondegree options like trade schools, apprenticeships, and “boot camps” has increased significantly, rising to 38 percent.

School counselors say it’s important for students to explore all available pathways after high school. Despite a lingering stigma around non-college options, many teens are focused on finding the best route to a successful career. Planning early and identifying personal strengths can help students make informed decisions about their futures.

Most Sunscreens Aren't Cutting It -- Here's How to Stay Safe in the Sun

Teen Health & Wellness - Mon, 2025-06-02 07:29
A new report from the Environmental Working Group (EWG) shows that most sunscreens on store shelves aren’t as safe or effective as you’d think. Out of over 2,200 products tested, fewer than 500 actually protect your skin the way they should. Some even include sketchy ingredients that could mess with your hormones or increase health risks.

The report calls out outdated rules and sneaky marketing that make it hard to know what’s safe. If you want to protect your skin (and avoid sunburns or worse), stick to lotions or sticks instead of sprays, go for fragrance-free options, and look for the EWG Verified® label. And don’t forget: Reapply often, wear a hat and sunglasses, and try to stay out of direct sun from 10 a.m. to 4 p.m.

Study quantifies the sleep loss and disruption experienced by new mothers

Teen Health 2 - Tue, 2025-05-27 10:48
Becoming a new mother brings more than just joyful chaos it delivers a profound and persistent sleep shock. A new study reveals that first-time moms lose not just total sleep, but crucial uninterrupted sleep, especially in the first week postpartum. While overall sleep gradually returns to normal, mothers continue to wake frequently, drastically disrupting sleep structure and leaving them exhausted. This fragmented sleep may even contribute to postpartum health issues, making continuity of rest not just total hours a vital target for interventions.
