COVID-19’s imaging features are variable and nonspecific, but the imaging findings reported thus far do show...

Rensselaer team finds solution to persistent problem facing potassium-metal batteries. Researchers demonstrate how they can overcome dendrites to create a metal battery that performs nearly as well as a lithium-ion battery, but relies on potassium – a much more abundant and less expensive element.

If you were to look inside a lithium-ion battery you’d typically find a cathode made of lithium cobalt oxide and an anode made of graphite. During charging and discharging, lithium ions flow back and forth between these two electrodes.

In this setup, if researchers were to simply replace lithium cobalt oxide with potassium cobalt oxide, performance would drop...

Some of the extremely low-density, “cotton candy like” exoplanets called super-puffs may actually have rings, according to new research published in The Astronomical Journal by Carnegie’s Anthony Piro and Caltech’s Shreyas Vissapragada

Super-puffs are notable for having exceptionally large radii for their masses – which would give them seemingly incredibly low densities...

The balance between weight gain and weight gain loss is predominantly determined by what you eat, how much you eat, and by how much exercise you get. But another important factor is often neglected… Published February 27 in the open-access journal PLOS Biology, research conducted by Kevin Kelly, Owen McGuinness, Carl Johnson and colleagues of Vanderbilt University, USA shows that it’s not just how many calories you eat, but WHEN you eat them that will determine how well you burn those calories.

Your daily biological clock and sleep regulate how the food you eat is metabolized; thus the choice of burning fats or carbohydrates changes depending on the time of day or night...
