Quantum Algorithms Conserve Time in the Calculation of Electron Dynamics

The calculations allow the electron densities and the changes after excitation to be determined with high spatial and temporal resolution. Here, the example of the lithium hydride molecule shows the shift of electron density from cyanide (red) to lithium (green) during a laser pulse. Credit: F. Langkabel / HZBScientists have examined the capacity of...

The Science Behind Honey’s Eternal Shelf Life

Honey - ancient liquid goldA multitude of factors-- its acidity, lack of water, and the existence of hydrogen peroxide-- function in absolute harmony, allowing honey to last forever.Modern archeologists excavating ancient Egyptian tombs have often discovered something unpredictable among the tombs' artifacts: pots of honey, thousands of years old and yet still completely preserved....

Dimethyl Ether Was Discovered in a Planet-forming Disc for the First Time

In a first for astrochemistry, astronomers have discovered dimethyl ether in a planet-forming disc. A precursor of larger organic molecules that can spur life, dimethyl ether is the largest molecule identified yet in a protoplanetary disc-- a rotating cloud of gas, dust, and ice that develops around a recently developing star and ultimately forms...
