Research team resolves decades-long problem in microscopy

Physics General News

18 April 2024

When viewing biological samples with a microscope, the light beam is disturbed if the lens of the objective is in a different medium than the sample. For example, when looking at a watery sample with a lens surrounded by air, the light rays bend more sharply in the air around the lens than in the...

Smoother surfaces make for better accelerators

Physics General News

18 April 2024

With every new particle accelerator built for research, scientists have an opportunity to push the limits of discovery. But this is only true if new particle accelerators deliver the desired performance—no small feat in a world where each new machine is a first of its particular kind. At each...

Research reveals a surprising topological reversal in quantum systems

Quantum Physics News

18 April 2024

In principle, one shouldn't compare apples to oranges. However, in topology, which is a branch of mathematics, one must do just that. Apples and oranges, it turns out, are said to be topologically the same since they both lack a hole—in contrast to doughnuts or coffee cups, for instance, which both...

Novel material supercharges innovation in electrostatic energy storage

Nanotechnology News

18 April 2024

Electrostatic capacitors play a crucial role in modern electronics. They enable ultrafast charging and discharging, providing energy storage and power for devices ranging from smartphones, laptops and routers to medical devices, automotive electronics and industrial equipment. However, the...

Skyrmions move at record speeds: A step towards the computing of the future

Physics General News

18 April 2024

An international research team led by scientists from the CNRS has discovered that the magnetic nanobubbles known as skyrmions can be moved by electrical currents, attaining record speeds up to 900 m/s....
