Retinal stimulation reveals colour never before seen by the human eye
A new retinal stimulation technique called Oz enabled volunteers to see colours that lie beyond the natural range of human vision. Developed by researchers at UC Berkeley, Oz works by stimulating...

Abnormal ‘Arnold’s tongue’ patterns appear in a real oscillating system
Synchronization studies: When the experimenters mapped the laser’s breathing frequency intensity in the parameter space of pump current and intracavity loss (left), unusual features appeared. The areas...
View ArticleTop-quark pairs at ATLAS could shed light on the early universe
Physicists working on the ATLAS experiment on the Large Hadron Collider (LHC) are the first to report the production of top quark–antiquark pairs in collisions involving heavy nuclei. By colliding lead...
View ArticleSupercritical water reveals its secrets
Contrary to some theorists’ expectations, water does not form hydrogen bonds in its supercritical phase. This finding, which is based on terahertz spectroscopy measurements and simulations by...

Dual-robot radiotherapy system designed to reduce the cost of cancer treatment
Researchers at the University of Victoria in Canada are developing a low-cost radiotherapy system for use in low- and middle-income countries and geographically remote rural regions. Initial...
View ArticleSuperconducting device delivers ultrafast changes in magnetic field
Precise control over the generation of intense, ultrafast changes in magnetic fields called “magnetic steps” has been achieved by researchers in Hamburg, Germany. Using ultrashort laser pulses, Andrea...
View ArticleSpeedy worms behave like active polymers in disordered mazes
Worms move faster in an environment riddled with randomly-placed obstacles than they do in an empty space. This surprising observation by physicists at the University of Amsterdam in the Netherlands...

Light-activated pacemaker is smaller than a grain of rice
The world’s smallest pacemaker to date is smaller than a single grain of rice, optically controlled and dissolves after it’s no longer needed. According to researchers involved in the work, the...
View ArticleSolar wind burst caused a heatwave on Jupiter
A burst of solar wind triggered a planet-wide heatwave in Jupiter’s upper atmosphere, say astronomers at the University in Reading, UK. The hot region, which had a temperature of over 750 K, propagated...
View ArticleCould an extra time dimension reconcile quantum entanglement with local...
Nonlocal correlations that define quantum entanglement could be reconciled with Einstein’s theory of relativity if space–time had two temporal dimensions. That is the implication of new theoretical...

Quantum transducer enables optical control of a superconducting qubit
Quantum transducer A niobium microwave LC resonator (silver) is capacitively coupled to two hybridized lithium niobate racetrack resonators in a paperclip geometry (black) to exchange energy between...
View ArticleNew research suggests gravity might emerge from quantum information theory
A new theoretical framework proposes that gravity may arise from entropy, offering a fresh perspective on the deep connections between geometry, quantum mechanics and statistical physics. Developed by...
View ArticleLayer-spintronics makes its debut
A new all-electrical way of controlling spin-polarized currents has been developed by researchers at the Singapore University of Technology and Design (SUTD). By using bilayers of recently-discovered...
View ArticleBrain region used for speech decoding also supports BCI cursor control
Sending an email, typing a text message, streaming a movie. Many of us do these activities every day. But what if you couldn’t move your muscles and navigate the digital world? This is where...
View ArticlePhotonic computer chips perform as well as purely electronic counterparts,...
Researchers in Singapore and the US have independently developed two new types of photonic computer chips that match existing purely electronic chips in terms of their raw performance. The chips, which...
View ArticleExoplanet could be in a perpendicular orbit around two brown dwarfs
The first strong evidence for an exoplanet with an orbit perpendicular to that of the binary system it orbits has been observed by astronomers in the UK and Portugal. Based on observations from the...
View ArticleFluid electrodes make soft, stretchable batteries
Researchers at Linköping University in Sweden have developed a new fluid electrode and used it to make a soft, malleable battery that can recharge and discharge over 500 cycles while maintaining its...
View ArticleAxion quasiparticle appears in a topological antiferromagnet
Physicists have observed axion quasiparticles for the first time in a two-dimensional quantum material. As well as having applications in materials science, the discovery could aid the search for...
