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.

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.

Midlife sleep habits may matter more than previously thought. A large study finds that poor sleep, alongside high blood pressure and nicotine use, sharply increases the risk of heart problems in menopausal women yet only 1 in 5 score well on overall heart health.

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 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.

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.

Teens are being misled by cannabis edibles dressed up like health foods. Bright colors, fruit imagery, and words like vegan make these products look fun, natural, and safe even when they re not. A WSU study warns that this could increase the risk of underage use and urges new packaging rules based on what actually appeals to teens.

Teens might finally have a good reason to sleep in on weekends within limits. A new study reveals that teenagers who get up to two extra hours of sleep on weekends show fewer anxiety symptoms than those who don t. But go beyond that sweet spot, and symptoms can actually increase.

Teens are diving into intense skincare routines inspired by TikTok, often slathering on six or more products daily, sometimes over ten in just minutes, chasing beauty ideals that favor lighter, flawless skin. But new research warns this digital trend comes at a high cost: irritation, allergies, and deep-seated social pressures around race and beauty.

Making a discovery with the potential for innovative applications in pharmaceutical development, a microbiology student has found a long sought-after fungus that produces effects similar to the semisynthetic drug LSD, which is used to treat conditions like depression, post-traumatic stress disorder and addiction.

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.

A new study suggests that boys who become overweight in their early teens risk damaging the genes of their future children, increasing their chances of developing asthma, obesity and low lung function.

A new study reveals a concerning decline in self-reported mental health among mothers in the United States between 2016 and 2023. The study also found modest but measurable declines in self-reported physical health during the same period.

Using a novel lab method they developed, researchers have identified nine molecules in the blood that were elevated in teens diagnosed with depression. These molecules also predicted how symptoms might progress over time. The findings of the clinical study could pave the way for earlier detection, before symptoms worsen and become hard to treat.

There's good news for people with migraine who take common drugs before or during pregnancy -- a new study found no increase in neurodevelopmental disorders such as autism and ADHD in their children. The study looked at drugs used for migraine attacks called triptans.

Researchers have shown that gonadotrophs, cells in the pituitary gland with a key role in puberty and reproduction, come from two different populations, with the majority produced after birth rather than in the embryo, as previously thought.

Researchers demonstrated unprecedented rates of recovery for spinal cord injuries. Individuals with incomplete spinal cord injury safely received a combination of stimulation of a nerve in the neck with progressive, individualized rehabilitation. This approach, called closed-loop vagus nerve stimulation (CLV), produced meaningful improvements in arm and hand function in these individuals.

The study explores how social influences, particularly peer pressure, impact substance use -- and misuse -- among young adults. A confidential online survey on alcohol use was given to 524 students at a large public university (not UTA).
