New research published in Science Advances, led by Yuan Yang, associate professor of materials science at Columbia Engineering, and collaborators at Lamont-Doherty Earth Observatory, demonstrates a novel technique for isolating isotopes.
Columbia Engineering researchers announced today that they have developed the first stand-alone, conformable, fully organic bioelectronic device that can not only acquire and transmit neurophysiologic brain signals, but can also provide power for device operation.
The study by researchers at New York University, Columbia Engineering, and the New York Genome Center, combines a deep learning model with CRISPR screens to control the expression of human genes in different ways—such as flicking a light switch to shut them off completely or by using a dimmer knob to partially turn down their activity. These precise gene controls could be used to develop new CRISPR-based therapies.
The Lightwave Research Lab has developed a fast and extremely efficient method for transferring huge amounts of data. The technique uses dozens of frequencies of light to transfer several streams of information over a fiber optic cable simultaneously.
A new study led by Columbia Engineering examines how different ways of participating in these markets affect the overall benefits of energy storage for society. The researchers used an agent-based computer framework--a model that simulates individual behaviors within complex systems--to simulate scenarios with renewable and storage capacity and market options.
A new study used global storm-resolving simulations and machine learning to create an algorithm that can deal with two different scales of cloud organization. This new approach addresses the missing piece of information in traditional climate model parameterizations and provides a way to predict precipitation intensity and variability more precisely.
A new study led by climate researchers at Columbia Engineering and the University of Exeter demonstrates that the treaty’s impact reaches all the way into the Arctic: its implementation is delaying the occurrence of the first ice-free Arctic by as much as 15 years.
Columbia synthetic biologists have developed a new method that uses engineered bacteria and AI to sense and record environmental signals. They are the first to engineer bacterial swarm patterns to visibly record their environment and use deep learning to decode patterns. This work could lead to applications ranging from monitoring environmental pollution to building living materials.
Columbia Engineering researchers have developed a new class of integrated photonic devices--“leaky-wave metasurfaces”--that convert light initially confined in an optical waveguide to an arbitrary optical pattern in free space. These are the first to demonstrate simultaneous control of all four optical degrees of freedom, setting a world record. Because they’re so thin, transparent, and compatible with photonic integrated circuits, they can be used to improve optical displays, LIDAR, optical communications, and quantum optics.
The National Science Foundation (NSF) announced today that it is awarding $20 million to establish the AI Institute for ARtificial and Natural Intelligence (ARNI), an interdisciplinary center led by Columbia University that will draw together top researchers across the country to focus on a national priority.
Columbia Engineering researchers explore the benefits and drawbacks of 3D-printed food technology, cooking 3D-printed food with lasers as part of the system, how 3D-printed food compares to the “normal” food we eat, and the future landscape of our kitchens.
Researchers have developed a new "camera" that sees the local disorder in materials. Its key feature is a variable shutter speed: because the disordered atomic clusters are moving, when the team used a slow shutter, the dynamic disorder blurred out, but when they used a fast shutter, they could see it. The method uses neutrons to measure atomic positions with a shutter speed of around one picosecond, a trillion times faster than normal camera shutters.
Columbia researchers invent a multimodal sequencing technique that achieves high-quality results from small volumes of frozen tumor specimens--the ability to study cancer tissues archived in biobanks should increase the number and variety of tumor samples available for scientific analysis and advance the discovery of biomarkers and drug targets.
Columbia Engineering neuroscientists identified a specific neural mechanism in the human brain that tags information with emotional associations for enhanced memory. The team demonstrated that high-frequency brain waves in the amygdala, a hub for emotional processes, and the hippocampus, a hub for memory processes, are critical to enhancing memory for emotional stimuli. Disruptions to this neural mechanism, brought on either by electrical brain stimulation or depression, impair memory specifically for emotional stimuli.
Columbia Engineering has won a $35 million five-year grant to establish the Center for Ubiquitous Connectivity (CUbiC) and advance energy-efficient communications technologies for addressing the vastly growing connectivity bottlenecks between data-hungry wireless devices and deluged data centers. Over the next five years, CUbiC will strive to flatten the computation-communication gap, delivering seamless Edge-to-Cloud connectivity with transformational reductions in the global system energy consumption.
Researchers at Columbia Engineering’s Lipson Nanophotonics Group have created visible lasers of very pure colors from near-ultraviolet to near-infrared that fit on a fingertip. The colors of the lasers can be precisely tuned and extremely fast – up to 267 petahertz per second, which is critical for applications such as quantum optics. The team is the first to demonstrate chip-scale narrow-linewidth and tunable lasers for colors of light below red -- green, cyan, blue, and violet.
Columbia Engineering researchers report that they have developed a new experimental pipeline to combine bacterial therapy with current cancer drugs. Their study, which explores resistance to bacterial therapy at the molecular level, has achieved better treatment efficacy without additional toxicity in laboratory models.
Mass transit, and subways in particular, are essential to the economic viability and environmental sustainability of cities across the globe. But public transit was hit hard during the COVID pandemic and subways especially experienced substantial drops in ridership.
Columbia researchers invent new method to treat obesity by using cationic nanomaterials that can target specific areas of fat and inhibit the unhealthy storage of enlarged fat cells. “Our studies highlight an unexpected strategy to treat visceral adiposity and suggest a new direction of exploring cationic nanomaterials for treating metabolic diseases,” said Columbia Engineering’s Biomedical Engineering Prof Kam Leong, a pioneer in using polycation to scavenge pathogens.
Columbia Engineering, with Florida Atlantic University, Rutgers University, University of Central Florida, and Lehman College, has won an NSF $26 million ERC grant to develop a center for smart streetscapes, focused on making cities more livable, safe, and inclusive. The underlying technologies of the new center will integrate advances in wireless/optical communications, edge/cloud computing, situational awareness, and privacy and security. Critical to its approach, CS3 will balance public data collection with community-defined benefits.
