Studies in both mice and thousands of children found links to symptoms like pain, constipation, and IBS. Scientists discovered that different biological pathways control different gut issues, hinting at more personalized treatments in the future. The research also highlights how a child’s early environment can have lasting physical effects—not just emotional ones.

A major review found clear benefits for children with conditions like autism and ADHD, yet far less data exists for typical childhood insomnia. Researchers also warn about mislabeled supplement doses and rising accidental ingestions among young kids. Experts say melatonin should be used carefully and only alongside proven behavioral sleep strategies.

Researchers studying a Swiss high school that introduced flexible start times found that students overwhelmingly chose to begin later—and ended up sleeping about 45 minutes longer each school night. The extra rest led to fewer sleep problems, better well-being, and improved academic performance.

Tapioca pearls made from cassava can absorb heavy metals like lead, and in large amounts they may slow digestion or even cause blockages. The drink is often loaded with sugar—sometimes more than soda—raising risks for cavities, obesity, diabetes, and fatty liver disease. There are even reports linking frequent consumption to kidney stones and poorer mental health.

By using advanced chemical screening on umbilical cord blood, scientists detected 42 different PFAS compounds, including many that standard tests do not routinely check for. These long lasting chemicals are found in common products like nonstick cookware, food packaging, and stain resistant fabrics, and they can build up in the body over time.

A new review of multiple studies found a consistent association between high consumption of beverages like soda, energy drinks, sweetened juices, and flavored milks and increased anxiety symptoms in adolescents. Wed, 18 Feb 2026 09:45:27 EST https://www.sciencedaily.com/releases/2026/02/260218044624.htm https://www.sciencedaily.com/releases/2026/02/260216044003.htm Researchers have built a realistic human mini spinal cord in the lab and used it to simulate traumatic injury. The model reproduced key damage seen in real spinal cord injuries, including inflammation and scar formation. After treatment with fast moving “dancing molecules,” nerve fibers began growing again and scar tissue shrank. The results suggest the therapy could eventually help repair spinal cord damage. Mon, 16 Feb 2026 07:41:25 EST https://www.sciencedaily.com/releases/2026/02/260216044003.htm https://www.sciencedaily.com/releases/2026/02/260215085001.htm Researchers tracked more than 400 toddlers to see whether mRNA COVID-19 vaccination during or just before pregnancy was linked to autism or developmental delays. After detailed assessments of speech, motor skills, behavior, and social development, they found no meaningful differences between vaccinated and unvaccinated groups. Experts say the results provide strong reassurance about vaccine safety in pregnancy. Sun, 15 Feb 2026 09:51:05 EST https://www.sciencedaily.com/releases/2026/02/260215085001.htm https://www.sciencedaily.com/releases/2026/02/260212234218.htm Scientists at Cedars-Sinai have uncovered a surprising repair system in the spinal cord that could open new doors for treating paralysis, stroke, and diseases like multiple sclerosis. They found that special support cells called astrocytes—located far from the actual injury—spring into action after damage. These “lesion-remote astrocytes” send out a protein signal, CCN1, that reprograms immune cells to efficiently clean up fatty nerve debris.

Tracking nearly 3 million people over decades, researchers found that while boys are diagnosed more often in childhood, girls steadily catch up during their teenage years. By early adulthood, autism diagnoses among males and females are nearly equal. Tue, 10 Feb 2026 09:19:46 EST https://www.sciencedaily.com/releases/2026/02/260210082921.htm https://www.sciencedaily.com/releases/2026/02/260207092904.htm A major study suggests menopause is linked to changes in brain structure, mental health, and sleep. Brain scans revealed grey matter loss in areas tied to memory and emotional regulation, while many women reported increased anxiety, depression, and fatigue. Hormone therapy did not reverse these effects, though it may slow age-related declines in reaction speed. Researchers say menopause could represent an important turning point for brain health.

A large study tracking more than 300,000 adults found that middle-aged and older night owls had poorer overall heart health and a higher risk of heart attack and stroke than those who were active earlier in the day, with the effect especially pronounced in women. Much of this elevated risk appeared to stem from lifestyle factors common among evening types, including smoking and inadequate sleep. Fri, 30 Jan 2026 11:05:26 EST https://www.sciencedaily.com/releases/2026/01/260130041101.htm https://www.sciencedaily.com/releases/2026/01/260130041056.htm Men start developing heart disease earlier than women, with risks rising faster beginning around age 35, according to long-term research. The difference is driven mainly by coronary heart disease, not stroke or heart failure. Traditional risk factors explain only part of the gap. The findings suggest earlier screening could help catch problems before serious damage occurs.

Researchers followed nearly 11,000 people from childhood into midlife and found that those with strong ADHD traits at age 10 were more likely to experience multiple physical health problems and health-related disability by their mid-40s. Sat, 24 Jan 2026 07:39:20 EST https://www.sciencedaily.com/releases/2026/01/260124073920.htm https://www.sciencedaily.com/releases/2026/01/260120000333.htm Scientists at Stanford Medicine have discovered a treatment that can reverse cartilage loss in aging joints and even prevent arthritis after knee injuries. By blocking a protein linked to aging, the therapy restored healthy, shock-absorbing cartilage in old mice and injured joints, dramatically improving movement and joint function. Human cartilage samples from knee replacement surgeries also began regenerating when exposed to the treatment.

Researchers analyzed 43 high-quality studies, including powerful sibling comparisons that help separate medication effects from genetics and family environment. Earlier warnings appear to have been driven by underlying maternal health factors such as fever or pain rather than the medication itself.

However, only Yueju Pill increased a brain-supporting protein associated with mood improvement. Brain imaging showed that unique network patterns—especially in visual regions—could predict who benefited most from Yueju Pill. This opens the door to more personalized depression treatments guided by brain scans.

The group showed higher inflammation, signs of liver strain and elevated neurofilament light chain, a marker of neuron injury. Low choline levels appeared closely tied to these changes. The results hint that early metabolic disruptions may quietly influence the brain long before symptoms emerge.

A large review of long-term studies shows that even very light smokers can see their risk of heart failure climb sharply. While quitting leads to major health improvements, some risk remains for decades. The safest approach is quitting entirely, especially at younger ages.

High SGK1 levels were found in the brains of suicide victims and in people with genetic variants linked to early adversity. Drugs that block SGK1 could offer a new kind of antidepressant, especially for patients resistant to SSRIs.

Researchers found that previous reviews often relied on weak or biased data, and most did not properly account for genetic or environmental factors shared by families. When these factors were considered, any apparent link between acetaminophen use and neurodevelopmental disorders largely disappeared.

Danish researchers discovered a measurable rise in cardiometabolic risk scores and a metabolic “fingerprint” in frequent screen users. Experts say better sleep and balanced daily routines can help offset these effects and safeguard lifelong health.
