Carbon defect in boron nitride creates first omnidirectional magnetometer
A newly discovered carbon-based defect in the two-dimensional material hexagonal boron nitride (hBN) could be used as a quantum sensor to detect magnetic fields in any direction – a feat that is not...
View ArticleWhat happens when a warp drive collapses?
Simulations of space–times that contain negative energies can help us to better understand wormholes or the interior of black holes. For now, however, the physicists who performed the new study, who...

Magnetically controlled prosthetic hand restores fine motion control
A magnetically controlled prosthetic hand, tested for the first time in a participant with an amputated lower arm, provided fine control of hand motion and enabled the user to perform everyday actions...
View ArticleNew superconductor has record breaking current density
A superconducting wire segment based on rare-earth barium copper oxide (REBCO) is the highest performing yet in terms of current density, carrying 190 MA/cm2 in the absence of any external magnetic...
View ArticleDark-matter decay could have given ancient supermassive black holes a boost
The decay of dark matter could have played a crucial role in triggering the formation of supermassive black holes (SMBHs) in the early universe, according to a trio of astronomers in the US. Using a...
View ArticleAdaptive deep brain stimulation reduces Parkinson’s disease symptoms
Deep brain stimulation (DBS) is an established treatment for patients with Parkinson’s disease who experience disabling tremors and slowness of movements. But because the therapy is delivered with...

View ArticleAir-powered computers make a comeback
A device containing a pneumatic logic circuit made from 21 microfluidic valves could be used as a new type of air-powered computer that does not require any electronic components. The device could help...
View ArticleThermal dissipation decoheres qubits
How does a Josephson junction, which is the basic component of a superconducting quantum bit (or qubit), release its energy into the environment? It is radiated as photons, according to new experiments...
View ArticleShort-range order always appears in new type of alloy
Short-range order plays an important role in defining the properties and performance of “multi-principal element alloys” (MPEAs), but the way in which this order develops is little understood, making...
View ArticleConvection enhances heat transport in sea ice
The thermal conductivity of sea ice can significantly increase when convective flow is present within the ice. This new result, from researchers at Macquarie University, Australia, and the University...
View ArticleLight-absorbing dye turns skin of a live mouse transparent
One of the difficulties when trying to image biological tissue using optical techniques is that tissue scatters light, which makes it opaque. This scattering occurs because the different components of...
View ArticleAmbipolar electric field helps shape Earth’s ionosphere
A drop in electric potential of just 0.55 V measured at altitudes of between 250–768 km in the Earth’s atmosphere above the North and South poles could be the first direct measurement of our planet’s...
