Optimality in self-organized molecular sorting

The eukaryotic cell is the basic unit of animals and plants. Through the microscope, it looks highly structured and subdivided in many membrane-bound compartments. Each compartment has a specific function, and its membrane ...

Experiment reveals new options for synchrotron light sources

Accelerator experts from the Helmholtz-Zentrum Berlin (HZB), the German federal metrology institute Physikalisch-Technische Bundesanstalt (PTB) and Tsinghua University in Beijing have used a laser to manipulate electron bunches ...

Machine learning aids in simulating dynamics of interacting atoms

A revolutionary machine-learning (ML) approach to simulate the motions of atoms in materials such as aluminum is described in this week's Nature Communications journal. This automated approach to "interatomic potential development" ...

Researchers produce beams of entangled atoms

Heads or tails? If we toss two coins into the air, the result of one coin toss has nothing to do with the result of the other. Coins are independent objects. In the world of quantum physics, things are different: Quantum ...

World's first video of a space-time crystal

A German-Polish research team has succeeded in creating a micrometer-sized space-time crystal consisting of magnons at room temperature. With the help of the scanning transmission X-ray microscope Maxymus at Bessy II at Helmholtz ...

High-throughput screening for Weyl semimetals with S4 symmetry

A new topological invariant χ is defined in systems with S4 symmetry to diagnose the existence of Weyl fermions. By calculating χ, the computational cost for searching Weyl semimetals is greatly reduced. Recently, Gao et ...

Quantum shuttle to quantum processor made in Germany launched

The quantum computer race is in full swing. Germany has long been one of the world leaders in basic research. An alliance between Forschungszentrum Jülich and the semiconductor manufacturer Infinion, together with institutes ...

Simply speaking while infected can potentially spread COVID-19

COVID-19 can spread from asymptomatic but infected people through small aerosol droplets in their exhaled breath. Most studies of the flow of exhaled air have focused on coughing or sneezing, which can send aerosols flying ...

New sensor paves way to low-cost sensitive methane measurements

Researchers have developed a new sensor that could allow practical and low-cost detection of low concentrations of methane gas. Measuring methane emissions and leaks is important to a variety of industries because the gas ...

New 'metalens' shifts focus without tilting or moving

Polished glass has been at the center of imaging systems for centuries. Their precise curvature enables lenses to focus light and produce sharp images, whether the object in view is a single cell, the page of a book, or a ...
