Online campaigns about humanitarian crises need to be more surprising if they are to successfully engage the public, according to an academic.

DNA sequencing to improve treatment of urinary infections

Urinary tract infections could be treated more quickly and efficiently using a DNA sequencing device the size of a USB stick -- according to new research. Researchers used a new device called MinION to perform nanopore sequencing to characterize bacteria from urine samples four times more quickly than using traditional methods of culturing bacteria. The new method can also detect antibiotic resistance -- allowing patients to be treated more effectively and improving stewardship of diminishing antibiotic reserves.

Coordinating traffic down the neuronal highway
