Scientists were wrong for decades about DNA knots

Scientists have discovered that DNA behaves in a surprising way when squeezed through tiny nanopores, overturning a long-held assumption in genetics research. What researchers once thought were knots causing messy electrical signals turn out to be something else entirely: twisted coils called plectonemes, formed as flowing ions inside the pore spin the DNA like a phone cord. These twists can linger and grow as DNA moves through, leaving clear electrical fingerprints.

Ancient Chinese medicine may hold the key to hair regrowth

A centuries-old Chinese medicinal root is getting new scientific attention as a potential game-changer for common hair loss. Polygonum multiflorum, long believed to restore dark, healthy hair, appears to work on multiple fronts at once—blocking hair-shrinking hormones, protecting follicles from damage, activating natural regrowth signals, and boosting blood flow to the scalp.

Scientists turn sunflower oil waste into a powerful bread upgrade

Researchers have found a surprising way to turn sunflower oil waste into a powerful bread upgrade. By replacing part of wheat flour with partially defatted sunflower seed flour, breads became dramatically richer in protein, fiber, and antioxidants—while also offering potential benefits for blood sugar and fat digestion.

A hidden Aloe vera compound takes aim at Alzheimer’s

Scientists have uncovered promising clues that compounds found in Aloe vera could play a role in fighting Alzheimer’s disease. Using advanced computer modeling, researchers discovered that beta-sitosterol—a natural plant compound—strongly interacts with two key enzymes involved in memory loss and cognitive decline. The compound showed stability, strong binding, and favorable safety indicators, making it a standout candidate for future drug development.

New drug resets the body clock and cuts jet lag recovery nearly in half

Scientists have identified a promising new compound, Mic-628, that can reliably shift the body’s internal clock forward—something that’s notoriously hard to do. By targeting a key clock-control protein, Mic-628 jump-starts the gene that sets daily rhythms, synchronizing both the brain’s master clock and clocks throughout the body. In mice experiencing simulated jet lag, a single dose cut recovery time nearly in half.

Scientists found a gut compound that helps protect the liver

What a mother eats during pregnancy may quietly shape her child’s liver health years down the road—but new research suggests there may be a way to tip the odds back in a healthier direction. Scientists found that a natural compound made by healthy gut bacteria dramatically reduced fatty liver disease in the offspring of mice whose mothers ate a high-fat, high-sugar diet. The compound, called indole, appeared to protect the liver, improve blood sugar, limit weight gain, and even reshape the gut microbiome in lasting ways.

Scientists find a missing link between Epstein-Barr virus and multiple sclerosis

New research suggests that Epstein-Barr virus may actively provoke the immune system in people with multiple sclerosis. Scientists found large buildups of virus-targeting immune cells in the nervous systems of MS patients, far more than in their blood. One viral gene was active only in people with MS, hinting at a direct role in the disease. The findings could help guide new approaches to treatment.

Doctors test brain cell implants to restore movement in Parkinson’s

Scientists at Keck Medicine of USC are testing an experimental stem cell therapy that aims to restore the brain’s ability to produce dopamine, the chemical whose loss drives Parkinson’s disease. The early-stage clinical trial involves implanting lab-grown dopamine-producing cells directly into a key movement-control region of the brain, with the hope of slowing disease progression and improving motor function.

Scientists just mapped the mutations that power cancer growth

Researchers have created the first complete map showing how hundreds of mutations in a key cancer gene affect tumor growth. By testing every possible mutation in a critical hotspot, they found that some changes barely boost cancer signals, while others supercharge them. When matched against real patient data, the map accurately predicted cancer behavior across tissues.

Two-month-old babies are already making sense of the world

At just two months old, babies are already organizing the world in their minds. Brain scans revealed distinct patterns as infants looked at pictures of animals, toys, and everyday objects, showing early category recognition. Scientists used AI to help decode these patterns, offering a rare glimpse into infant thinking. The results suggest babies begin learning and understanding far sooner than expected.
