Scientists observe ‘negative time’ in quantum experiments
Experimental physicist Daniela Angulo poses with a device in her physics lab at the University of Toronto. Scientists have long known that light can sometimes appear to leave a material before it enters it, but this effect can be interpreted as an illusion caused by how waves are distorted by the material. It has been ignored. Now, through innovative quantum…

Researchers observe nanoscale water formation in real time
Water bubbles coming out of palladium nanocubes. Observed with a transmission electron microscope. Scale bar corresponds to 50 nanometers. Credit: Vinayak Dravid/Northwestern University For the first time, researchers have witnessed hydrogen and oxygen atoms combining to form tiny nano-sized water bubbles in real time and on a molecular scale. The incident occurred as part of a new study at Northwestern…
