Usually diagnosed in children, teens and young adults, type 1 diabetes is an autoimmune disease in which the immune system attacks and destroys insulin-secreting β-cells in the pancreas. As a result, people with type 1 diabetes can’t regulate their blood sugar levels and require insulin treatment for survival. Now, researchers reporting in ACS Applied Materials & Interfaces have reversed new-onset type 1 diabetes in mice with pyramid-like DNA molecules called tetrahedral framework nucleic acids (tFNAs).

When an important document lands on your desk, you might file it away for safekeeping. The same thing happens with our memories: They first appear in one part of the brain and then move to another for long-term storage in a process known as memory consolidation.

MIT biologists show that enlargement of blood stem cells restricts their ability to generate new blood cells during aging.

In an unexpected discovery, Georgetown University Medical Center researchers have identified what appears to be a significant vascular defect in patients with moderately severe Parkinson’s disease. The finding could help explain an earlier outcome of the same study, in which the drug nilotinib was able to halt motor and nonmotor (cognition and quality of life) decline in the long term.

In an unprecedented atlas, researchers begin to map how genes are turned on or off in different cells, a step toward better understanding the connections between genetics and disease

New research has identified a way of using nanoclusters to bolster waning antibiotics.

A technique that measures the metabolic activity of bacteria with an electric probe can identify antibiotic resistance in less than 90 minutes, a dramatic improvement from the one to two days required by current techniques.

Nontoxic drug delivery system could lead to effective therapies for currently untreatable cancers
