While Rare, Why Do Batteries Sometimes Catch Fire and Explode?
Key Takeaways Scientists have gained new insight into why thermal runaway, while rare, could cause a resting battery to overheat and catch fire. In order to better understand how a resting battery might undergo thermal runaway after fast charging, scientists are using a technique called "operando X-ray microtomography" to measure changes in the state of charge at the particle level inside a lithium-ion battery after it's been charged.

Infrared aurorae discovered at Uranus
Infrared aurorae discovered at Uranus
Planetary scientists including UCL's Professor Steve Miller have detected the infrared aurorae of the ice giant Uranus after searching for more than 30 years, in a new study published in Nature Astronomy. On Earth, the Northern and Southern Lights (aurorae) occur as a result of the interaction between the stream of charged particles known as the solar wind and our magnetic field, which funnels the particles in our atmosphere around the poles.

In a surprising finding, light can make water evaporate without heat
A newly identified process could explain a variety of natural phenomena and enable new approaches to desalination. Evaporation is happening all around us all the time, from the sweat cooling our bodies to the dew burning off in the morning sun. But science's understanding of this ubiquitous process may have been missing a piece all this time.

Astronomers measure the distance between Earth and 200 galaxies
Astronomers measure the distance between Earth and 200 galaxies
In 2022, the James Webb Space Telescope captured an image of a cluster of thousands of galaxies. Astronomers have measured the distance to Earth of 200 of these galaxies. On July 11, 2022, the world saw the very first image taken by the James Webb Space Telescope (JWST). The image is now known as the "Webb Deep Galaxy Field" - a galaxy cluster named SMACS 0723, comprising over 7,000 galaxies! This image has proved an important target for the study of galaxy evolution, as this large number of very distant galaxies tells us a lot about how galaxies formed and evolved in the early Universe.

Interacting polarons
Interacting polarons
In physics, the complex processes in solids are often described in terms of quasiparticles. In ultracold quantum gases, these quasiparticles can be reproduced and studied. Now, for the first time, Innsbruck scientists led by Rudolf Grimm have been able to observe in experiments how Fermi polarons - a special type of quasiparticle - can interact with each other.

FNRS researcher Tárcius Nascimento Ramos publishes in the prestigious Journal of Chemical Physics
Knowing the energy of light absorbed by a molecule enables us to understand its structure, its quantum states, its interaction with other molecules and its potential technological applications. Molecules with a high probability of simultaneously absorbing two low-energy photons of light have a wide range of applications: as molecular probes in high-resolution microscopy, as substrates for data storage in dense three-dimensional structures or as vectors in medicinal treatments.
