Charmonium’s onion-like structure is revealed by new calculations
Calculations by physicists in China and the US suggest that the charmonium meson has a distinct onion-like structure. The team used a simplified version of quantum chromodynamics (QCD) and extensive...

Low-frequency ultrasound triggers targeted drug delivery
Conventional medication is often limited by low drug effectiveness or intolerable side effects caused by the drug reaching parts of the body where it’s not needed. As such, there’s increasing interest...
View Article‘Poor man’s Majoranas’ offer testbed for studying possible qubits
Majorana particles could be an important component in quantum computers – if they exist. Using a new approach, physicists at QuTech in the Netherlands say they have now found fresh hints that...
View ArticleMatter-wave interferometry puts new limits on ‘chameleon particles’
A matter-wave interferometer has measured the effect of gravity on individual atoms at the highest precision to date. That is according to its creators in the US and Italy, who built their instrument...
View ArticleLiquid metal interfaces show large thermoelectric effect
The thermoelectric effect is much stronger at the interface of two liquid metals than it is in solid-solid or solid-liquid systems. This discovery, from researchers at the Ecole Normale Supérieure...
View ArticleInverse Mpemba effect seen in a trapped-ion qubit
The inverse Mpemba effect has been observed in a quantum bit (qubit). The research was done at the Weizmann Institute in Israel and suggests that under certain conditions a cooler trapped-ion qubit may...

Quantum-entangled photons are super-sensitive to Earth’s rotation
All in a spin: Two indistinguishable photons (red lines) are incident on a beamsplitter cube and become entangled. The two photons are then coupled into an optical fibre-based interferometer, which is...

Scientists create space plasmas at CERN
Producing plasma: A proton (far left) from the Super Proton Synchrotron (SPS) accelerator at CERN impinges on carbon nuclei (small grey spheres). This produces a shower of various elementary particles,...

Lung images reveal how breathing distribution differs between the sexes
Key differences Example EIT exams in a man (a) and a woman (b). The waveforms show the tidal variation of the EIT signal, while the images show the distribution of tidal impedance variation (the...
View ArticleSingle electrons follow structured chiral paths
Electrons have been sent along structured chiral paths by researchers in Germany. The researchers say their work, which is analogous to work done with photons in 2010, achieves chirality in...
View ArticleSpin-ice superconductors display magnetic nonreciprocity
Researchers in China have fabricated a new hybrid superconducting device from a special type of material known as an artificial spin ice (ASI). The innovative structure, which is made of asymmetric...

Fluorescent dye helps reveal the secrets of ocean circulation
Seawater located more than 2 km below the ocean’s surface drives the oceanic circulation that helps regulate the Earth’s climate. At these depths, turbulent mixing drives water towards the surface in a...
View ArticlePrimordial black holes contain very little dark matter, say astronomers
When the gravitational wave detectors LIGO and VIRGO observed signals from merging black holes with masses much higher than those of black holes that form from the collapse of stars, scientists were...

Portable camera expands the applications of gamma imaging
Gamma imaging is a nuclear medicine technique employed in over 100 different diagnostic procedures. Also known as scintigraphy, the approach uses gamma cameras to image the distribution of...
View ArticleSun-like stars seen orbiting hidden neutron stars
Astronomers have found strong evidence that 21 Sun-like stars orbit neutron stars without losing any mass to their binary companions. Led by Kareem El-Badry at the California Institute of Technology,...
View ArticleHow do electromagnetic waves carry information about objects they interact with?
As electromagnetic waves travel, they collect information about their environment. This property is widely exploited in a host of applications that rely on waves being deflected, scattered or reflected...
View ArticleX(3960) is a tetraquark, theoretical analysis suggests
A theoretical study has confirmed that a particle observed at CERN’s LHCb experiment in 2022 is indeed a tetraquark – supporting earlier hypotheses that were based on the analysis of its observed decay...

Shifting day-night cloud patterns may be making climate change worse
It is a curious fact of climate science that clouds can both cool the Earth’s surface and keep it warm. This apparent paradox occurs because during the day, clouds reflect shortwave sunlight back into...
