Waves Move Across the Human Brain to Support Memory

Columbia Engineers have discovered a new fundamental feature of brain oscillations: they actually move rhythmically across the brain, reflecting patterns of neuronal activity that propagate across the cortex. The researchers also found that the...

Single Molecular Insulator Pushes Boundaries of Current State of the Art

Researchers have synthesized the first molecule capable of insulating at the nanometer scale more effectively than a vacuum barrier. The team’s insight was to exploit the wave nature of electrons. By designing an extremely rigid silicon-based...

New Research Finds Tall and Older Amazonian Forests More Resistant to Droughts

A new Columbia Engineering study shows that photosynthesis in tall Amazonian forests--forests above 30m--is 3x less sensitive to precipitation variability than in shorter forests of less than 20m. Taller Amazonian forests were also found to be...

Columbia Engineers Invent a Non-Invasive Technique to Correct Vision

Columbia Engineers have developed a non-invasive approach to permanently correct vision that shows great promise in preclinical models. The method uses a femtosecond oscillator for selective and localized alteration of the biochemical and...

New Study First to Demonstrate a Chip-Scale Broadband Optical System that Can Sense Molecules in the Mid-Infrared

Researchers at Columbia Engineering have demonstrated, for the first time, a chip-based dual-comb spectrometer in the mid-infrared range, that requires no moving parts and can acquire spectra in less than 2 microseconds. The system, which consists...

Researchers Hide Information in Plain Text

Columbia Engineering computer scientists invent FontCode, a way to embed hidden information in ordinary text by imperceptibly changing the shapes of fonts in text. The hidden information persists even when documents or images with perturbed texts...
