You’re standing at a bus stop, waiting for a ride that seems like it will never come. At first, you’re hopeful that it will be here any second. But as the minutes laggardly drag on, doubt creeps in. Should you keep waiting, or is it smarter to start walking or call for a ride?

“It’s a classic dilemma. “Do you persist with the belief that the bus is on its way, or do you cut your losses and move on to something else?” asks Joe Kable, a psychologist in the School of Arts & Sciences at the University of Pennsylvania. The question isn’t just whether you have the patience to wait, he says. “It’s about understanding when it pays off to stick with something and when cutting your losses is the better choice.”

Kable draws parallels to two competing ideas ...

Rethinking the Quantum Chip

New research demonstrates a brand-new architecture for scaling up superconducting quantum devices. Researchers at the UChicago Pritzker School of Molecular Engineering (UChicago PME) have realized a new design for a superconducting quantum processor, aiming at a potential architecture for the large-scale, durable devices the quantum revolution demands.

Unlike the typical quantum chip design that lays the information-processing qubits onto a 2-D grid, the team from the Cleland Lab has designed a modular qua...

Mars’ Infamous Dust Storms can Engulf the Entire Planet: A new study examines how

Dust storms on Mars could one day pose dangers to human astronauts, damaging equipment and burying solar panels. New research gets closer to predicting when extreme weather might erupt on the Red Planet.

Today’s weather report on Mars: Windy with a chance of catastrophic dust storms blotting out the sky.

In a new study, planetary scientists at the University of Colorado Boulder have begun to unravel the factors that kick off major dust storms on Mars — weather events that sometimes engulf the entire planet in swirling grit. The team discovered that relatively warm and sunny days may help to trigger them.

Heshani Pieris, lead author of the study, said the findings are a first step toward forecasting extreme weather on M...

Industry-funded Study Suggests Coffee really is the Fountain of Youth

CNC-Center for Neuroscience and Cell Biology researchers in Portugal report that regular, moderate coffee consumption (three cups per day) not only contributes to a longer life but also enhances the quality of those additional years by reducing the risk of major age-related diseases and maintaining better overall health.

Coffee consumption’s perception has shifted from potentially harmful to potentially beneficial over the last several decades. Scientific understanding of the underlying mechanisms by which coffee’s primary components, namely caffeine and chlorogenic acids, influence fundamental biological processes and are understood to have alertness, antioxidant and anti-inflammatory properties, though how these might be involved in aging remains unclear.
