'Lab on a chip' can measure protein-DNA interactions

New nanophotonic tweezers developed by Cornell researchers can fit on a chip less than one-inch square, making it easier and more efficient to manipulate single molecules using light in order to investigate biological systems.

Earthquake depth impacts potential tsunami threat

Earthquakes of similar magnitude can cause tsunamis of greatly varying sizes. This commonly observed, but not well-understood phenomenon has hindered reliable warnings of local tsunamis.
