Scientists have created the highest resolution map of the dark matter that threads through the Universe – showing its influence on the formation of stars, galaxies and planets.
Even with regular brushing, teeth can become stained from genetic factors or consuming foods and drinks like tomatoes and coffee. Chemical whiteners can help, but they can also damage teeth in the process. So, researchers reporting in ACS Nano have designed a prototype teeth-whitening powder that is activated by the vibrations from an electric toothbrush. The system both brightened and protected teeth in lab demonstrations.
Together with an international team, researchers from the Molecular Physics Department at the Fritz Haber Institute revealed how atoms rearrange themselves before releasing low-energy electrons in a decay process initiated by X-ray irradiation. For the first time, they gain detailed insights into the timing of the process – shedding light on related radiation damage mechanisms.
Muons are particles used to study fundamental physics and to image large structures such as volcanoes, bridges and ancient buildings. But despite their apparent benefits to science – and even society more broadly – muons only have a half-life of around one microsecond. Now researchers at the University of Plymouth have suggested a means of overcoming that, using intense laser pulses to reduce the rate of decay and at least double the muon’s lifetime.
Avishesh Neupane, assistant extension professor of soil science in the College of Agriculture, Health and Natural Resources, conducted a laboratory experiment to see if adding the chemical element manganese to soil could help reduce nitrogen runoff in agricultural soil.
He published these results in Applied Soil Ecology.
Until this study, no research had directly tested how manganese affects nitrogen cycling under agronomically relevant conditions.
