Rare Particle Decay at CERN: What LHCb's One-in-Ten-Billion Result Means
What would count as evidence for something that happens about once in ten billion decays? LHCb's new result is a useful way into quarks, antiparticles and the problem of finding a small signal in a huge amount of data.
Is It Cheaper to Leave the Heating On All Day? The Physics of Heat Loss
A house is not a flask that stays warm once it has been heated. Follow where its energy goes, why reheating does not automatically erase a saving, and why advice for a gas boiler cannot simply be copied onto a heat pump.
What Is a Superconductor? Zero Resistance and New Research Explained
A superconducting coil can carry a large current without ordinary resistive heating. That is useful, but it does not make an entire machine energy-free. Start with resistance, then see what this week's research adds to a much harder question.

How Does the Large Hadron Collider Work? A Guide for Physics Pupils
The Large Hadron Collider gives particles energy, brings them into collisions and measures what comes out. Follow a proton around the machine to see how electric fields, magnets and detectors make that possible.
ATLAS Observes a Rare Way to Make Top Quarks at the LHC
ATLAS has identified a rare way of producing a top quark in earlier Large Hadron Collider (LHC) data. The useful questions are what a top quark is, what makes this interaction different and how researchers know the signal is there.

Why Are Fireworks Different Colours? The Physics Behind Bonfire Night
A firework display gives you two good physics questions: what makes the colours, and why do you see the flash before hearing the bang? Start with the simple explanation, then connect the display to photons and electron energy levels.
Do Solar Panels Work in Winter and on Cloudy Days? The Physics Explained
Yes, solar panels can generate electricity in winter and under cloud. The useful questions are how much light reaches them, for how long, and how much becomes electrical energy. Cold weather and low winter output are not the same thing.

Why Is There Condensation on My Windows? The Physics Explained
A wet window on a cold morning is a change of state happening in your home. Follow the water from the air to the glass, then see what temperature, ventilation and insulation each change.
ESA Hera Mission 2026: Can We Deflect an Asteroid?
NASA hit an asteroid with DART in 2022. ESA's Hera will examine the result up close. The useful physics starts with a collision, a change in momentum and the debris thrown out afterwards.
Can Light and Sound Exchange Energy? A New Optical-Fibre Experiment
An optical fibre can carry light and vibrations at the same time. New research shows a particularly strong interaction between them during a single pass. Here is what that means, starting with the waves you know from school.

NASA PRIMA Space Telescope: How It Differs from James Webb
NASA announced the next development step for PRIMA on 23 September. It is not a replacement for James Webb: it is designed to measure longer-wavelength infrared light and answer different questions.
How Do Heat Pumps Work in Cold Weather? The Physics of 300% Efficiency
A heat pump can supply more heat than the electrical energy it uses. The missing part of the explanation is an extra input: energy taken from outdoors. Here is how that still works when the air feels cold.

How Does Regenerative Braking Work? Electric Cars, Trains and Energy Recovery Explained
An electric car can charge its battery while slowing down. Follow the energy from the wheels to the battery, and discover why regenerative braking is useful but cannot recover everything.
BepiColombo Mercury Arrival 2026: Date, Mission and Why Reaching Mercury Is So Hard
Getting to Mercury is not simply a matter of pointing a rocket towards the Sun. BepiColombo has spent years reshaping its orbit so that it can stay beside a fast-moving planet instead of rushing past.

Why Does a Football Curve? The Physics of Free Kicks and the Magnus Effect
A football curves when an off-centre kick gives it spin. The spinning ball changes the airflow and pushes its wake sideways, so the air pushes back on the ball in the opposite direction. That sideways Magnus force continually changes the direction of the ball's velocity and bends its path.
Roman Space Telescope Launch 2026: UK Time, How to Watch and What It Will Discover
NASA is targeting Sunday 30 August for the launch of the Nancy Grace Roman Space Telescope. Here is the UK launch time, where to watch, how Roman differs from Hubble and Webb, and how it will use infrared light, gravitational microlensing and a coronagraph to investigate exoplanets, dark matter and dark energy.

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.
