Bacterial infection could contribute to Alzheimer’s disease

Researchers in the UK have used DNA sequencing to examine bacteria in post-mortem brains from patients with Alzheimer’s disease. Their findings suggest increased bacterial populations and different proportions of specific bacteria in Alzheimer’s, compared with healthy brains. The findings may support evidence that bacterial infection and inflammation in the brain …

Understanding the 3D molecular structure of nanoobjects

Understanding the 3D molecular structure of important nanoobjects like proteins and viruses is crucial in biology and medicine. With recent advances in X-ray technology, scientists can now collect diffraction images from individual particles, ultimately allowing researchers to visualize molecules at room temperature. However, determining 3D structure from these single-particle diffraction …

Treatments of drug-resistant bugs by using nanotechnology

Antibiotic resistance is a growing problem, especially among a type of bacteria that are classified as “Gram-negative.” These bacteria have two cell membranes, making it more difficult for drugs to penetrate and kill the cells. Researchers from MIT and other institutions are hoping to use nanotechnology to develop more targeted treatments …
