Liquid water is confirmed to be present at depths of 10 to 20 km (6.2 to 12.4 mi) below the surface of Mars, based on a new analysis of data from NASA's InSight lander. [ 384 ] An Earth-sized, ultra-short period exoplanet called TOI-6255b is found to be undergoing extreme tidal distortion, caused by the close proximity of its parent star.
The quantum tunneling of water occurs when water molecules in nanochannels exhibit quantum tunneling behavior that smears out the positions of the hydrogen atoms into a pair of correlated rings. [1] In that state, the water molecules become delocalized around a ring and assume an unusual double top-like shape.
Molecular physics is the study of the physical properties of molecules and molecular dynamics. The field overlaps significantly with physical chemistry, chemical physics, and quantum chemistry. It is often considered as a sub-field of atomic, molecular, and optical physics. Research groups studying molecular physics are typically designated as ...
However, a great deal of current experimental work is devoted to synthetic systems such as artificial self-propelled particles. [ 8 ] [ 9 ] [ 10 ] Active matter is a relatively new material classification in soft matter : the most extensively studied model, the Vicsek model , dates from 1995.
Liquid water and ice emit radiation at a higher rate than water vapour (see graph above). Water at the top of the troposphere, particularly in liquid and solid states, cools as it emits net photons to space. Neighboring gas molecules other than water (e.g. nitrogen) are cooled by passing their heat kinetically to the water.
3 January: A free online index with metadata about over 200 million scientific documents is launched, OpenAlex. [1]The graphs show one visualization of recent developments of science overall based on this data (fewer papers may not be associated with decreasing success, priority, impact or activity).
Mar. 2—It may seem like a recent trend for more women to be entering STEM fields, but women have a long history of contributing to innovations in science, technology, engineering and mathematics.
Quantum physics is a branch of modern physics in which energy and matter are described at their most fundamental level, that of energy quanta, elementary particles, and quantum fields. Quantum physics encompasses any discipline concerned with systems that exhibit notable quantum-mechanical effects, where waves have properties of particles, and ...
