Gravitational wave signal tests Einstein’s theory of general relativity

The gravitational wave, a ripple in space-time set off by two black holes colliding, reached U.S.-based Laser Interferometer Gravitational-Wave Observatories in January 2025.

Underwater 3D printing could transform maritime construction

An interdisciplinary collaboration has developed a way to 3D-print concrete underwater – a technique that could transform on-site maritime construction and the repair of critical infrastructure.

Environmental DNA breakthrough will aid conservation efforts

Researchers developed a new model that can predict where a sampled particle of eDNA likely originated in a water body.

NYC residents agree: heat pumps improve comfort

Residents of a 10-unit apartment building retrofitted with electric heat pumps preferred the pumps to their oil-fueled boiler.

New technique puts rendered fabric in the best light

Cornell researchers, in partnership with the technology company NVIDIA, have developed a method for creating digital images of cloth that more accurately captures the texture, sheen and translucence of textiles. 

Supersonic tests defy a 70-year-old rule of metal strength

Smaller grains – the microscopic crystal regions within the material – normally make metal stronger, but when deformed at extreme speeds, this rule flips and metals with very small grains actually become softer, new Cornell research reveals.

Kotlikoff to December grads: ‘Meet the future with confidence’

More than 500 graduates and 2,000 friends and family celebrated at the 23rd December Recognition Ceremony on Dec. 21.

Unexpected allies: DNA packaging aids gene expression

Researchers discovered that DNA packaging structures called nucleosomes, which have been traditionally seen as roadblocks for gene expression, actually help reduce torsional stress in DNA strands and facilitate genetic information decoding.

2025 Year in Review

Cornell’s impact was felt near and far, from the lacrosse fields to research labs and beyond in a turbulent 2025.
