Researchers link patterns seen in spider silk, melodies

Researchers at MIT have created an analogy between the physical structure of spider silk and the sonic structure of a melody, showing that the structure of each relates to its function in an equivalent way. The study reveals that structural patterns are directly related to functional properties such as lightweight strength and sonic te...

New target found for aggressive cancer gene

Researchers have discovered a new target for treating aggressive cancers driven by the Myc oncogene, which can be targeted by inhibiting enzymes that are unique to cancer cells. The study identified SAE2 as a potential candidate gene that slows growth rates of human breast cancer cells when depleted.

Climate change driving tropical birds to higher elevations

A new study by Duke University researchers has found that tropical birds are moving to higher elevations in response to climate change, but at a slower rate than predicted. The animals appear to be tracking changes in vegetation rather than migrating rapidly, suggesting a delay in their response to warming temperatures.

Few hospitals aggressively combat catheter-associated urinary tract infections

A nationwide survey found that few hospitals are aggressively combating catheter-associated urinary tract infections, a common healthcare-associated infection. The study suggests that hospitals may not be using enough prevention practices for UTIs, despite increased use of methods to prevent other hospital-acquired infections.

Kidney injury: A serious risk to the health and survival of today's soldiers

A study found that acute kidney injury (AKI) is common among military personnel with burns and wounds sustained during combat in Iraq and Afghanistan. The study also revealed a significant increase in mortality rates among patients with AKI, with death rates ranging from 0.2% to 65.1%. By preventing or modifying kidney injury, research...
