Quantum Fluid First

For the first time, Columbia researchers have found a delicate phase of matter in a monolayer 2D semiconductor, work that could be used in future quantum computing.

The image illustrates monolayer WSe2 hosting "composite fermions", a quasi-particle that forms due to the strong interactions between electrons and is responsible for the sequence of fractional quantum Hall states.

Correcting the Record on a COVID Protein

For membrane protein expert Tim Cross, the call to solve the structure of a misunderstood protein in COVID-19 has put retirement on hold.

Drug-Target Dragnet

Inside the virus that causes COVID-19 are thousands of potential drug targets. As part of a global team, Lucio Frydman is hunting for the best candidates.

Lucio Frydman is part of a global team of science detectives leaving no stone unturned in their hunt for a weakness in the virus that causes COVID-19.

The Mystery of the Vanishing Crust

Using a novel technique, researchers uncover secrets hidden deep below the surface of our planet.

The scientists examined hundreds of basalt samples taken along the global ridges that contain recycled ancient oceanic crust in varying amounts. "Depleted" segments of the ridge received less than "normal" amounts of recycled crust, while "enriched" segments contained a larger proportion of recycled crust.

Stemming the Spread of COVID-19

A team of experts believes stem cells could be a route to a fast, effective therapy.

MagLab biomedical engineer Sam Grant is studying how stem cell therapies could be aimed against COVID-19.

    Magnetoelectric coupling at a transition between two spin states

    Materials with magnetoelectric coupling - a combination of magnetic and electric properties - have potential applications in low-power magnetic sensing, new computational devices and high-frequency electronics. Here, researchers find a new class of magnetoelectric materials controlled by spin state switching.

    Molecular magnetic building blocks

    This study reports the first transition metal compounds featuring mixed fluoride–cyanide ligands. A significant enhancement of the magnetic anisotropy, as compared to the pure fluoride ligated compounds, is demonstrated by combined analysis of high-field electron paramagnetic resonance (HF-EPR) spectroscopy and magnetization measurements.
