Materials for superconducting qubits

The connection between microscopic material properties and qubit coherence are not well understood despite practical evidence that material imperfections present an obstacle to applications of superconducting qubits. In a ...

Geneticists map the rhinoceros family tree

There's been an age-old question going back to Darwin's time about the relationships among the world's five living rhinoceros species. One reason answers have been hard to come by is that most rhinos went extinct before the ...

Martian snow is dusty, could potentially melt, new study shows

Over the last two decades, scientists have found ice in many locations on Mars. Most Martian ice has been observed from orbital satellites like NASA's Mars Reconnaissance Orbiter. But determining the grain size and dust content ...

How cells measure themselves

Ever since scientists discovered cells under the microscope more than 350 years ago, they have noted that each type of cell has a characteristic size. From tiny bacteria to inches-long neurons, size matters for how cells ...

Being social generates larger genomes in snapping shrimp

In an article scheduled to publish in PNAS, on June 7, 2021, a team of researchers led by Columbia University's Dustin R. Rubenstein, a Professor of Ecology, Evolution and Environmental Biology, found that within the same ...

How army ants' iconic mass raids evolved

Army ants form some of the largest insect societies on the planet. They are quite famous in popular culture, most notably from a terrifying scene in Indiana Jones. But they are also ecologically important. They live in very ...
