Optomechanical control of molecular motion

Optomechanical control of molecular motion

Physics

By DIPC

At first glance, molecules seem too small and too chaotic to be controlled with light. Their atoms jiggle ceaselessly, driven by thermal energy, and their vibrations—tiny oscillations of chemical bonds—usually remain hidden in the background. But recent work has shown that we can, in fact, use light not only to measure these vibrations but also […]

Is space-time structure, substance or metaphor?

Is space-time structure, substance or metaphor?

Philosophy of sciencePhysics

By Invited Researcher

Author: Daryl Janzen, Observatory Manager and Instructor, Astronomy, University of Saskatchewan Few ideas in modern science have reshaped our understanding of reality more profoundly than space-time — the interwoven fabric of space and time at the heart of Albert Einstein’s theory of relativity. Space-time is frequently described as the “fabric of reality.” In some accounts […]

Plutonium has captured the attention of scientists since its discovery in the early 1940s. This enigmatic element has an important role to play in emerging energy technologies like nuclear batteries and reactors, but it also has complicated electronic behavior that causes some intriguing effects. Its electron structure contributes to unconventional entropic properties at low temperatures […]

Selective reduction and its reversibility: a crystal that <i>breathes</i> oxygen

Selective reduction and its reversibility: a crystal that breathes oxygen

A team of scientists has discovered a new type of crystal that can “breathe”—releasing and absorbing oxygen repeatedly at relatively low temperatures. This unique ability could transform the way we develop clean energy technologies, including fuel cells, energy-saving windows, and smart thermal devices. The newly developed material is a special kind of metal oxide made […]

Why didn’t the universe annihilate itself moments after the big bang? A new finding at Cern on the French-Swiss border brings us closer to answering this fundamental question about why matter dominates over its opposite – antimatter. Author: William Barter, UKRI Future Leaders Fellow, University of Edinburgh Much of what we see in everyday life […]

Kirigami, inverse design with no advanced computational tools

MathematicsPhysics

Kirigami is a traditional Japanese art form that entails cutting and folding paper (origami is just folding it) to produce complex three-dimensional (3D) structures or objects. Over the past decades, this creative practice has also been applied in the context of physics, engineering, and materials science research to create new materials, devices and even robotic […]

The light of someone’s life might not be just another person, but light in the literal sense. According to a recent study , every living system emits light without requiring external excitation due to a biological phenomenon known as ultraweak photon emission (UPE). In mice, UPE was linked to vitality as live mice emitted significantly […]
