Mathematical model sheds light on how exercise suppresses tumour growth
Physical exercise plays an important role in controlling disease, including cancer, due to its effect on the human body’s immune system. A research team from the USA and India has now developed a...
View ArticleVertical-nanowire transistors defeat the Boltzmann tyranny
A new transistor made from semiconducting vertical nanowires of gallium antimonide (GaSb) and indium arsenide (InAs) could rival today’s best silicon-based devices. The new transistors are switched on...
View ArticleExtended cosmic-ray electron spectrum has a break but no other features
A new observation of electron and positron cosmic rays has confirmed the existence of what could be a “cooling break” in the energy spectrum at around 1 TeV, beyond which the particle flux decreases...

Conditioning prepares aluminium-ion batteries for real-world use
Imagine a smartphone that charges faster, lasts longer and is more eco-friendly – all at a lower cost. Aluminium-ion batteries (AIBs) could make this dream a reality, and scientists are working to...
View ArticleSquishy silicone rings shine a spotlight on fluid-solid transition
People working in industry, biology and geology are all keen to understand when particles will switch from flowing like fluids to jamming like solids. With rigid particles, and even for foams and...

Quantum processor enters unprecedented territory for error correction
Researchers at Google Quantum AI and collaborators have developed a quantum processor with error rates that get progressively smaller as the number of quantum bits (qubits) grows larger. This...
View ArticleGenerative AI has an electronic waste problem, researchers warn
The rising popularity of generative artificial intelligence (GAI), and in particular large language models such as ChatGPT, could produce a significant surge in electronic waste, according to new...

Laser beam casts a shadow in a ruby crystal
Particles of light – photons – are massless, so they normally pass right through each other. This generally means they can’t cast a shadow. In a new work, however, physicist Jeff Lundeen of the...
View ArticleQuantum uncertainty and wave–particle duality are equivalent, experiment shows
The orbital angular momentum states of light have been used to relate quantum uncertainty to wave–particle duality. The experiment was done by physicists in Europe and confirms a 2014 theoretical...
View ArticleImmiscible ice layers may explain why Uranus and Neptune lack magnetic poles
When the Voyager 2 spacecraft flew past Uranus and Neptune in 1986 and 1989, it detected something strange: neither of these “ice giant” planets has a well-defined north and south magnetic pole. This...
View ArticleInner workings of the neutron illuminated by Jefferson Lab experiment
A cutting-edge experiment that probes the internal structure of the neutron has been done at Jefferson Lab in the US. An international collaboration used the CEBAF Large Acceptance Spectrometer...

View ArticleOptimization algorithm improves safety of transcranial focused ultrasound...
Transcranial focused ultrasound is being developed as a potential treatment for various brain diseases and disorders. One big challenge, however, is focusing the ultrasound through the skull, which can...
View ArticleSupramolecular biomass foam removes microplastics from water
A reusable and biodegradable fibrous foam developed by researchers at Wuhan University in China can remove up to 99.8% of microplastics from polluted water. The foam, which is made from a...
View ArticleSolar wind squashed Uranus’s magnetosphere during Voyager 2 flyby
Some of our understanding of Uranus may be false, say physicists at NASA’s Jet Propulsion Laboratory who have revisited Voyager 2 data before and after its 1986 flyby of this ice-giant planet. The new...
View ArticleCross-linked polymer is both stiff and stretchy
A new foldable “bottlebrush” polymer network is both stiff and stretchy – two properties that have been difficult to combine in polymers until now. The material, which has a Young’s modulus of 30 kPa...
View ArticleEntanglement entropy in protons affects high-energy collisions, calculations...
An international team of physicists has used the principle of entanglement entropy to examine how particles are produced in high-energy electron–proton collisions. Led by Kong Tu at Brookhaven National...
