Integrated transcriptomic profiling combined with in vitro validation reveals the involvement of TMEM140 in the link between periodontitis and brain aging
CONCLUSION: Through integrated transcriptomic analysis together with in vitro experimental validation, this study indicates that TMEM140 may be a candidate bridge molecule connecting PD and AD comorbidity. TMEM140 may participate in shaping the peripheral-central immunosenescence network and contribute to the cross-system transmission of inflammatory signaling.
Scientists discover a new way to prevent gum disease without killing good bacteria
Scientists have uncovered a surprising way to influence the bacteria living in our mouths — not by killing them, but by interrupting how they “talk” to each other. Researchers found that dental plaque bacteria use chemical signals to coordinate growth, and by blocking those signals, they were able to encourage healthier bacteria while reducing disease-linked microbes tied to gum disease. Even more intriguing, the bacterial conversations changed depending on oxygen levels above and below the gums, revealing an entirely new layer of complexity inside the mouth.

What scientists found inside coral reefs could change the future of medicine
Beneath the beauty of coral reefs lies a hidden universe of microbes unlike anything scientists expected. Each coral species supports its own specialized microbial partners, many of which have never been studied before. These microbes produce a stunning variety of chemical compounds with potential uses in medicine and biotech. The discovery highlights just how much is at stake as coral reefs face growing threats.

Doctors warn this popular vitamin may quietly disrupt cancer care
Many cancer patients turn to biotin supplements hoping to restore hair lost during treatment, but experts warn the popular vitamin may do more harm than good. While biotin is often marketed for stronger hair and nails, there’s little evidence it actually helps cancer-related hair loss—and it can dangerously interfere with lab tests. Doctors say the supplement can distort key blood markers, potentially masking cancer recurrence or delaying treatment decisions.
Scientists find natural compounds that hit COVID-19 from every angle
A little-known tree from Brazil’s Atlantic Forest may hold a surprising weapon against COVID-19. Researchers discovered that compounds called galloylquinic acids, extracted from its leaves, can attack SARS-CoV-2 on multiple fronts—blocking the virus from entering cells, disrupting its replication, and even dampening harmful inflammation. Unlike many antivirals that target just one part of the virus, these natural compounds act in several ways at once, potentially making it harder for resistance to develop.
