Why pressure can make electric-car batteries last longer
University of Cambridge researchers found that keeping lithium-ion pouch-cell electrodes under a carefully controlled stack pressure could double their cycle life. Too little pressure encouraged cathode cracking, while too much promoted lithium plating, so the result is about finding a narrow engineering balance rather than simply squeezing a battery harder.
How heat-transfer fins help phase-change materials store energy faster
Three-dimensional simulations show that several well-spaced fins can melt a phase-change material more effectively than one large fin. The reason is not just extra conduction: liquid in the gaps starts circulating and transfers energy, while fins placed too close together can interfere with one another.

Euclid discovers the most ancient quasars: how redshift lets us see the early Universe
ESA's Euclid telescope has found 31 extremely early quasars, including the record-holder at redshift 7.77. Their stretched light shows how spectra and infrared observations let physicists study the young Universe.
Room-temperature quantum material controls quantum light on a chip
A Nature study reports a patterned gold-chip material that can sort and preserve selected quantum properties of light at room temperature, pointing to new photonic technologies without claiming a room-temperature quantum computer.
CERN sees a wake in quark-gluon plasma
CMS scientists at CERN have observed a diffusion wake left by fast quarks and gluons in quark-gluon plasma, giving physicists a new way to study matter that filled the Universe shortly after the Big Bang.

Why AI data centres use so much electricity
AI is rapidly increasing data-centre demand, but the physics is clearer than the headlines: electrical power runs the processors, and nearly all of that energy ultimately has to leave the building as heat.
Tiny infrared chip could spot heat leaks and gases more clearly
MIT researchers have made a chip-based infrared device whose tiny pixels can be controlled independently, potentially helping compact cameras detect heat leaks, gases and atmospheric pollutants.
Scientists recreate rotating black-hole wave physics without a black hole
A CUNY team has used a stationary ring of rapidly modulated electronic resonators to reproduce rotational super-radiance: a wave can gain energy from effective rotation and leave amplified.

Quantum computers model molten salt for fusion fuel
Oak Ridge National Laboratory, Cleveland Clinic and IBM have used a hybrid quantum-classical workflow to calculate how tritium interacts with FLiBe, a molten salt being studied for future fusion reactor blankets.
AI helps physics models predict rare extreme heatwaves
Researchers have combined fast AI weather forecasts with physics-based climate modelling so rare, dangerous heatwaves can be sampled more efficiently and studied with better statistics.

Attosecond microscope tracks electron tunnelling in space and time
An ultrafast scanning tunnelling microscope has followed electron wave packets over attoseconds and atomic distances, revealing a 500-attosecond response delay and a practical space-time limit for electron imaging.
Single trapped ion maps tiny electromagnetic fields above a chip
ETH Zurich researchers moved one laser-cooled beryllium ion through three dimensions to map electric and magnetic fields above a chip, detecting oscillating fields as small as 10 nanovolts per metre.
Quantum computer simulates quark string breaking with 104 qubits
A 104-qubit IBM processor has reproduced string breaking in a simplified particle-physics model, showing how quantum hardware could eventually help physicists calculate the formation of hadrons after collisions.
