Graphene switch combines logic and memory functions in a single device
Researchers at Manchester University in the UK have used graphene to make a new electrically-controlled switching device that supports both memory and logic functions. The device, which exploits...
View ArticleTuberculosis-specific PET tracer could enable more effective treatment
In 2022, more than 10.5 million people fell ill with tuberculosis (TB) and an estimated 1.3 million people died from this curable and preventable disease. TB is currently diagnosed using clinical...
View ArticleSpins hop between quantum dots in new quantum processor
A quantum computing system that uses the spins of holes in germanium quantum dots has been unveiled by researchers in the Netherlands. Their platform is based on a 1998 proposal by two pioneers of...

Icy exoplanet found to be potentially habitable
A research team headed up at the University of Montreal has discovered that the temperate exoplanet LHS 1140 b may have an atmosphere, could be covered in ice, and may even have an ocean of liquid...
View ArticleTwisted carbon nanotubes store more energy than lithium-ion batteries
Mechanical watches and clockwork toys might seem like relics of a bygone age, but scientists in the US and Japan are bringing this old-fashioned form of energy storage into the modern era. By making...
View ArticleSmashing heavier ions creates superheavy livermorium
Physicists have used a beam of titanium-50 to create the element livermorium. This is the first time that nuclei heavier than calcium-48 have been used to synthesize a superheavy element. The...

Sound waves move objects in liquid
Researchers in Switzerland have found a way of using sound waves to manipulate objects in disordered environments such as liquids. Instead of trapping the objects as conventional optical and acoustic...
View Article‘Event-responsive’ electron microscopy focuses on fragile samples
A new scanning transmission electron microscope (STEM) technique that modulates the electron beam in response to the scattering rate allows images to be formed with the fewest electrons possible. The...

First patients treated using minibeam radiation therapy
Spatially fractionated radiotherapy is a novel cancer treatment that uses a pattern of alternating high-dose peaks and low-dose valleys to deliver a nonuniform dose distribution. Numerous preclinical...
View ArticlePhysicists detect nuclear decay in the recoil of a levitating sphere
Physicists in the US have detected the nuclear decay of individual helium nuclei by embedding radioactive atoms in a micron-sized object and measuring the object’s recoil as a particle escapes from it....
View ArticleKirigami cubes make a novel mechanical computer
A new mechanical computer made from an array of rigid, interconnected plastic cubes can store, retrieve and erase data simply by stretching the array and manipulating the position of the cubes. The...
View ArticleOur world (still) cannot be anything but quantum, say physicists
Is the behaviour of quantum objects described by a simple, classical theory? Or can particles really be in a superposition of different places at once, as quantum theory suggests? In 1985, the...
View ArticleLiquid water could abound in Martian crust, seismic study suggests
An ocean’s worth of liquid water could be trapped within the cracks of fractured igneous rocks deep within the Martian crust – according to a trio of researchers in the US. They have analysed seismic...
View ArticlePhotonic orbitals shape up
Photons in arrays of nanometre-sized structures exhibit more complex behaviour than electrons in conventional solid-state materials. Though the two systems are sometimes treated as analogous,...

Quantum oscillators fall in synch even when classical ones don’t – but at a cost
The synchronized flashing of fireflies in summertime evokes feelings of marvel and magic towards nature. How do they do it without a choreographer running the show? For some physicists, though, these...

Wearable PET scanner allows brain scans of moving patients
Imaging plays a vital role in diagnosing brain disease and disorders, as well as advancing our understanding of how the human brain works. Existing brain imaging modalities, however, usually require...

Physicists reveal the role of ‘magic’ in quantum computational power
Two phases: In the entanglement-dominated phase (left), efficient quantum algorithms exist for performing computational tasks such as entanglement distillation and dilution. In contrast, the...
View ArticleQuantum dot liquid scintillator could revolutionize neutrino detection
Neutrino detectors contain up to tens of thousands of tonnes of liquid scintillator that emits a flash of light whenever it interacts with a neutrino. Such scintillators are typically organic compounds...
