Overuse and misuse of antibiotics leading to rise of resistant strains of pathogenic bacteria

November 15, 2016

Prolonged preventive antibiotics after incision closure do not prevent infections, but they do change the composition of bacteria in the host at other anatomic locations. The result is resistant colonization of the patient and potentially an infection with Clostridium difficile, shown here. (credit: CDC)

A super-high-resolution snapshot of RNA folding

Could lead to future discoveries in basic biology, gene expression, RNA viruses, and disease
November 4, 2016

This matrix of the RNA folding pathway shows how the transcription length and nucleotide positions change over time. (Nucleotide position is along the x-axis; transcription length is along the y-axis.) Each pixel in the matrix is a piece of information about the structure of the RNA molecules.
