force : any of the natural influences (as electromagnetism, gravity, the strong force, and the weak force) that exist especially between particles and determine the structure of the universe — Webster
Forces in the universe are based on four fundamental interactions. The strong and weak forces are nuclear forces that act only at very short distances, and are responsible for the interactions between subatomic particles, including nucleons and compound nuclei. The electromagnetic force acts between electric charges, and the gravitational force acts between masses. All other forces in nature derive from these four fundamental interactions. For example, friction is a manifestation of the electromagnetic force acting between the atoms of two surfaces, and the Pauli exclusion principle, which does not permit atoms to pass through each other. Similarly, the forces in springs, modeled by Hooke’s law, are the result of electromagnetic forces and the Exclusion Principle acting together to return an object to its equilibrium position. Centrifugal forces are acceleration forces that arise simply from the acceleration of rotating frames of reference — Wikipedia

A new technique has been developed allowing reliable atomic-resolution images to be taken, for the first time, of hybrid photoactive perovskite thin films - highly favorable materials for efficient photovoltaic and optoelectronic applications. These images have significant implications for improving the performance of solar cell materials and have unlocked the next level of ability to understand these technologically important materials.

They look like microscopic bottle brushes: Polymers with a backbone and tufts of side arms. This molecular design gives them unusual abilities: For example, they can bind active agents and release them again when the temperature changes. With the help of neutrons, a research team has now succeeded to unveil the changes in the internal structure in course of the process.

This November the newest member of the EU's Copernicus program, Sentinel-6 Michael Freilich, will take to the heavens from Vandenberg Air Force Base in California. The satellite is named after NASA's former Director of Earth Observation and is a radar altimetry mission to monitor sea-level rise, wave-height and windspeed.

Burnt orange daytime skies signal that the consequences of climate change are already here. But while we tend to focus on the death and destruction resulting from the growing frequency and severity of wildfires and other disasters, we often pay less heed to the ways their costs ricochet through the financial system, with the potential for widespread collateral damage.

A new normal is taking shape as a warming planet is changing hurricane behaviors and patterns. Research over the last decade has shown alarming trends resulting in more destructive hurricanes. Global trends suggest hurricanes are getting stronger, moving more slowly over land, and deviating farther north and south of the equator.
