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.

Wed, 20 May 2026 08:54:32 EDT https://www.sciencedaily.com/releases/2026/05/260519224334.htm https://www.sciencedaily.com/releases/2026/05/260515002146.htm Scientists are uncovering a surprising link between hidden tooth infections and blood sugar problems. Deep infections around tooth roots can create chronic inflammation that spreads through the body and may interfere with insulin function. 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.

Prof. Mayer Brezis’s review exposes global data showing psychiatric harm and a pattern of inaction by Merck and the FDA. Despite its cosmetic use, the drug’s effects on brain chemistry can be devastating. Brezis calls for urgent regulatory reforms and post-marketing studies to protect public health.

By encapsulating it in polymers, they created a powdered form for oral hygiene products. This could replace antibiotics, avoid side effects from existing treatments, and help vulnerable patients maintain oral health.

By targeting a uniquely permeable gum tissue called the junctional epithelium, this new method stimulates immunity right where many infections enter: the mouth, nose, and lungs. Using dental floss on mice to apply a flu vaccine triggered a robust immune response—better than existing oral approaches and comparable to nasal vaccines, but without the risks. It even worked with mRNA and protein-based vaccines.

When applied to surfaces like medical implants or surgical tools, the engineered resilin forms nano-droplets that physically disrupt bacterial cells, including antibiotic-resistant strains like MRSA, without harming human tissue. In lab tests, the coating was 100% effective at keeping bacteria from sticking and forming biofilms, a key cause of infection after surgery.
