Shipwrecks off NC coast harbor tropical migrants

A new study by Duke University scientists reveals that tropical and subtropical fish are taking up residence on shipwrecks and other sunken structures off the North Carolina coast. The artificial reefs created by these structures serve as stepping stones for fish moving northward in search of suitable habitat.

Study reveals how social relationships transform bird flocks

Researchers found that paired jackdaws use less energy in flight, but the existence of pairs inhibits the way information passes between birds, reducing the flock's ability to react to disturbances. This challenges current models of collective behavior in nature.

A barrier that keeps cancer at bay

Researchers found that activin B and ALK7 expressed by cancer cells form a barrier that prevents tumor formation and metastasis. The 'barrier' triggers apoptosis in cancer cells, but can be evaded by downregulating activin B or ALK7.
