Optogenetic therapy shows promise for vision restoration
Retinitis pigmentosa is an inherited degenerative condition that destroys photoreceptors in the retina and can eventually lead to irreversible blindness. In a clinical trial first, an international...
View ArticleDisordered environments around tumour cells can promote cancer spread
A new study showing how tumour cells behave when surrounded by a disordered microenvironment could help cancer researchers by providing a biophysics model describing how cancers spread within the human...
View ArticleFastest star in the Milky Way feels the rotation of our central black hole
At the centre of our galaxy lies a supermassive black hole, Sagittarius A* (Sgr A*), that’s more than four million times the mass of the Sun. Astronomers have now discovered the fastest-known star in...

Nuclear clocks finally see the light
Two independent teams have realized the first clocks based on transitions within atomic nuclei. The new nuclear clocks represent the culmination of more than 20 years of research and could become vital...
View ArticleCollisions between dipolar molecules ‘switch off’ at low energies
Researchers in the Netherlands have shown that they can turn off the dipole moment of molecules that are normally polar, drastically altering the molecules’ behaviour in low-energy collisions. The...

Titanium-polymer metamaterial floats in water
Open-cell metallic structures are widely employed in the aerospace industry and in biomedical applications that require materials to be extremely light as well as strong. In marine infrastructure,...
View ArticleExciton wavefunctions come into view
Physicists have experimentally reconstructed the quantum probability distribution of an exciton for the first time using super-fast spectroscopy. By simultaneously capturing the spatial and momentum...

Radiotherapy trials shape future treatments of brain metastases
At this week’s ASTRO 2026 meeting in Boston, MA, researchers shared the results of clinical trials addressing important and longstanding questions in cancer care. In a dedicated news briefing...
View ArticleScientists explain how a 300 TeV photon could reach Earth
On 9 October 2022, a gamma-ray burst called GRB 221009A sent an enormous amount of high-energy radiation toward Earth. The Large High Altitude Air Shower Observatory (LHAASO) detected thousands of...
View ArticleDNA computer settles in thermodynamic equilibrium
A DNA computer that calculates as it settles into thermal equilibrium has been unveiled in Ireland. Drawing together several earlier lines of research, Damien Woods and colleagues at Maynooth...
View ArticlePolymer-tuned perovskite creates high-efficiency underwater solar cells
Terrestrial solar cells rely on capturing a broad spectrum of sunlight, particularly the low-energy, long-wavelength red and infrared regions between 800 and 1150 nm. Emulating this concept underwater...
View ArticleHeavy water isotopes make weather predictions more accurate
Weather forecasting relies on many different types of data to make accurate predictions: temperature, humidity and wind data are all used to build an accurate forecast. Researchers have now found a new...
View ArticleSingle-photon measurements confirm Richard Feynman’s vision of quantum mechanics
Physicists have confirmed the two foundational postulates of Richard Feynman’s path-integral approach to quantum mechanics in a real-world experiment for the first time. This comes nearly 80 years...

Miniature microprobe enables internal imaging of smaller blood vessels than...
Cardiovascular disease is the leading cause of death globally, with atherosclerotic disease – caused by the build-up of fatty plaques in the arteries – responsible for around three-quarters of these...
View ArticleDirty magnetite nanoparticles keep cleaning up dyes
Each year, approximately 5000 tonnes of dyes (about 50 times the weight of a blue whale) are discharged into industrial wastewater. These dyes block light from reaching aquatic plants and animals,...

Einstein’s equivalence principle put to two new tests
A new quantum test of the weak equivalence principle performed on the China Space Station using cold atom interferometry is the most precise to date, yielding an uncertainty of 2.8 x 10-8 and a test...
View ArticleProton–oxygen collisions put cosmic-ray models to the test
Physicists at CERN have recreated the collisions that trigger cosmic-ray air showers in Earth’s atmosphere. Results from the ATLAS experiment on the Large Hadron Collider (LHC) show that none of the...
View ArticleMicrobes may survive at the Moon’s south pole
The Moon’s polar regions may be less hostile to microbes than previously thought. This is the new finding from researchers at NASA and the University of Maryland in the US who say that future manned...
View ArticleTiny biodegradable stars enhance drug delivery to the skin
Delivering drugs directly to the skin provides a targeted means of treating dermatological conditions while minimizing side effects. The approach is limited, however, by the stratum corneum – the...
