Illustration of nSWAT mechanism stretching DNA molecules
“Resonator” wave guides made of silicon nitride, represented here by gray bars, apply enough force to half-micron-wide plastic beads (blue) to perform a standard biophysical experiment, unzipping DNA molecules held in place by light emanating from the resonator at the point of each bead.

‘Lab on a chip’ can measure protein-DNA interactions

Cornell Chronicle

New nanophotonic tweezers developed by Cornell researchers can stretch and unzip DNA molecules as well as disrupt and map protein-DNA interactions, paving the way for commercial availability.

Fear of majority-minority changes perceptions of race

Cornell Chronicle

The threat of demographic change may alter who white Americans perceive as racial minorities, potentially making more people vulnerable to discrimination, suggests new Cornell psychology research.

Water crisis increased Flint children’s lead exposure

Cornell Chronicle

As many as one in four children in Flint, Michigan – far above the national average – may have experienced elevated blood lead levels after the city’s 2014 water crisis, finds new research by Jerel Ezell, assistant professor in the Africana Studies and Research Center.

Illustration of two black holes
LIGO/Caltech/MIT/Sonoma State (Aurore Simonnet) An artist's conception of a precessing binary black hole. The black holes, which will ultimately spiral together into one larger black hole, are shown here orbiting one another in a plane. The black holes are spinning in a non-aligned fashion, which means they are tilted relative to the overall orbital motion of the pair. This causes the orbit to precess like a top spinning along a tilted axis.

Binary black hole spin behavior revealed using novel techniques

Cornell Chronicle

Research done at Cornell has uncovered the first potential signs of spin-orbit resonances in binary black holes, a step toward understanding the mechanisms of supernovas and other big questions in astrophysics.

Many common labels for this region’s Indigenous people and places, including Taughannock Falls, shown here in a photo from 1888, are actually mispronunciations imposed by white settlers, according to professor Kurt Jordan. His brief history of the Gayogo̱hó:nǫ’ people in the Cayuga Lake region seeks to clarify local history; this image appears in the book.
