There is growing demand for smart materials that can change their physical properties in response to various external stimuli such as light, heat, pressure, magnetic fields and electric fields. One such physical property is the magnetic state of material complexes, which depends

England's public libraries are being quietly eroded, according to a major new study from the University of Sheffield. With physical collections shrinking and maintenance budgets falling in real terms, the research warns that libraries risk becoming unable to meet the diverse need

Dark matter accounts for 85% of the matter in the universe, but scientists still do not know what it is made of. A study, published in Physical Review Letters, by Rice University researchers proposes a detector design that could help search for axions, hypothetical particles that

Researchers from the Molecular Physics and Physical Chemistry departments of the Fritz Haber Institute have shown how two highly synchronized infrared (IR) laser beams can control molecules as they switch between different structural conformations. Their study provides a new wind

Short-lived sources of radio radiation in the sky, known as radio transients, can originate in the vicinity of supermassive black holes in the centers of galaxies. They are the result of processes that take place under extreme physical conditions. While most radio transients asso

Werner Heisenberg's famous uncertainty principle describes one of the most intriguing features of quantum physics: certain pairs of physical quantities describing a particle, such as position and momentum, cannot simultaneously be determined with arbitrary precision—not because o

Viscosity is one of the most fundamental physical properties used to describe how materials flow. It governs the movement of liquids, molten rocks and even slowly deforming regions deep inside the Earth. While scientists have long studied materials with low or moderate viscositie

When a human cell prepares to split into two daughter cells, it must first construct a tiny internal machine called the mitotic spindle—a structure of protein fibers that physically pulls chromosomes apart and deposits one set into each new cell. Get the spindle the right size an

Nature has invented countless types of pointy appendages, and scientists have long sought to explain what makes these structures so effective at puncturing other things. A new study models the key physical characteristics of puncturing tools to reflect their diversity in nature,

By combining approaches from two rapidly growing fields of quantum physics, researchers at Penn State and Saint Louis University have demonstrated that a novel specialized material can naturally enable a new way to study unusual physical phenomena known as non-Hermitian dynamics.

A new Tufts University imaging facility is doing something that most microscopy centers in the world cannot: allowing scientists to examine a butterfly wing, a living tissue or a microchip and reveal its physical structure, molecular chemistry and elemental composition across eve

A new study in PLOS Biology of 133 species of flies, mosquitoes and their relatives shows that most species fly in surprisingly similar ways. Physical and aerodynamic laws shape the evolution of their flight behavior more strongly than previously thought. Mosquitoes prove to be a
