New evidence that teeth can fill their own cavities
A drug developed to combat Alzheimer’s Disease can trigger regeneration of tooth dentin.
- New research into the drug Tideglusib clarifies what it can do for damaged teeth.
- Tooth dentin can be regrown instead of needing to be replaced with man-made composite.
- Only particular cavities need apply.
Artificial intelligence yields new antibiotic
A deep-learning model identifies a powerful new drug that can kill some antibiotic-resistant bacteria.
Using a machine-learning algorithm, MIT researchers have identified a powerful new antibiotic compound. In laboratory tests, the drug killed many of the world's most problematic disease-causing bacteria, including some strains that are resistant to all known antibiotics. It also cleared infections in two different mouse models.
Could heart disease actually be contagious?
A new hypothesis suggests that you can "catch" noncommunicable diseases from other people via the microbiome.
- A newly published hypothesis suggests that some noncommunicable diseases can actually be transmitted between people via their microbiomes.
- A new analysis even found that your microbiome can convey more information than your genes about your chance of developing various health conditions.
- By being exposed to an unhealthy cluster of microbes, healthy people could put themselves at risk of "catching" noncommunicable diseases.
Antibiotic resistance: Researchers have directly proven that bacteria can change shape inside humans to avoid antibiotics
Antibiotic resistance poses one of the biggest threats to global public health.
Widespread antibiotic use is largely to blame for the emergence of antibiotic resistant bacteria, which is currently one of the biggest threats to global health.
The best hospitals have more superbugs. Do patients have a right to know?
The premier hospitals tend to have the most superbugs — they also have the best experts.
- Many of the best hospitals also have superbugs within their walls.
- One medical dilemma is whether to tell patients about a superbug's presence: will it inhibit them from seeking care?
- The best hospitals may have the most superbugs, but they also have the experts who know how to treat patients sickened by bacteria, and possess some of the most powerful antibiotics around.
