Our spine, eyes, teeth, pelvis, and even certain nerves all reveal compromises that worked well enough for survival but still leave us prone to pain, injury, and disease. Structures like the appendix and ear muscles also remain because they were never harmful enough for evolution to eliminate. Together, these features tell the story of a body shaped by history rather than perfection.

Studies found that people who underwent root canal treatment often experienced better blood sugar control and reduced inflammation afterward. The research suggests that treating an infected tooth could have benefits far beyond the mouth. Fri, 15 May 2026 00:21:46 EDT https://www.sciencedaily.com/releases/2026/05/260515002146.htm https://www.sciencedaily.com/releases/2026/05/260508024125.htm 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. Fri, 08 May 2026 05:27:16 EDT https://www.sciencedaily.com/releases/2026/05/260508024125.htm https://www.sciencedaily.com/releases/2026/05/260502013550.htm Scientists have discovered a way to help the brain clean itself of harmful Alzheimer’s plaques by activating its own support cells.

Tue, 10 Feb 2026 04:56:56 EST https://www.sciencedaily.com/releases/2026/02/260208233841.htm https://www.sciencedaily.com/releases/2026/01/260108231335.htm Sugar-loving mouth bacteria create acids that damage teeth, but arginine can help fight back. In a clinical trial, arginine-treated dental plaque stayed less acidic, became structurally less harmful, and supported more beneficial bacteria. These changes made the biofilms less aggressive after sugar exposure. The results point to arginine as a promising, natural addition to cavity-prevention strategies. Fri, 09 Jan 2026 20:34:00 EST https://www.sciencedaily.com/releases/2026/01/260108231335.htm https://www.sciencedaily.com/releases/2026/01/260106001916.htm A familiar mouth bacterium best known for causing cavities may also be quietly influencing the brain. Scientists found that when this microbe settles in the gut, it produces compounds that can travel through the bloodstream and harm neurons involved in movement. In animal studies, this process triggered inflammation, motor problems, and brain changes linked to Parkinson’s disease. The findings hint that protecting oral and gut health could help protect the brain as well.

These implants need to be small and flexible to mimic circumstances inside the human body. However, the environment within the body is corrosive, which raises concerns about the durability of implantable silicon ICs. A team of researchers address this challenge by studying the degradation mechanisms of silicon ICs in the body and by coating them with soft PDMS elastomers to form body-fluid barriers that offer long-term protection to implantable chips. These findings not only enhance the longevity of implantable ICs but also significantly broaden their applications in the biomedical field.
