Phys.org / Contact lenses can repair themselves with just one hour of UV light exposure
Contact lenses are a great vision correction option for many, but if one of them gets damaged, there is little to do other than throw it away. A team reporting in ACS Applied Polymer Materials has a solution: special polymer ...
Phys.org / Hidden seismicity patterns before large earthquakes uncovered
When and where the next large earthquake will strike remains one of the most difficult questions in geoscience. Researchers from the GFZ Helmholtz Center for Geosciences led by Dr. Sadegh Karimpouli and Prof. Dr. Patricia ...
Phys.org / Espresso 'pucks' stop behaving predictably above certain pressures
When a physics student asked baristas at the Warsaw Coffee Conference what their biggest question for scientists was, the baristas said they wanted to know how to stop channeling during brewing.
Phys.org / Amazon fish reveal a synchronized survival tactic that could transfer to drone swarms
Some fish swim in synchrony. Others, it turns out, breathe in synchrony. This is true for arapaimas, an obligate air-breathing species living in the Amazon. A new study in Communications Biology, led by the Leibniz Institute ...
Phys.org / Honeybee metamorphosis map uncovers 842 active DNA switches that drive worker bee development
Researchers have identified "DNA switches" that become active as honeybee larvae grow into worker bees, offering new insight into the development of these important pollinators and the ecosystems they support.
Phys.org / Solid-state material turns visible light into high-energy UV at sunlight intensity, expanding solar energy potential
Two cups of warm water don't make one cup of boiling water. But in the quantum world, multiple low-energy photons can combine to produce a single, higher-energy photon.
Phys.org / Scientists create optical skyrmions using a two-century-old light phenomenon
Nanyang Technological University, Singapore (NTU Singapore) scientists have used a classic optical phenomenon known as the Poisson spot to create stable patterns of light called optical skyrmions, which are tiny, swirling ...
Phys.org / Local species trends may flag global extinction risk, global study finds
New research from the University of St. Andrews has shown that higher extinction risk is associated with a higher frequency of decreasing local prevalence of species, in an analysis of one of the most comprehensive long-term ...
Phys.org / Hidden dark force may slow cosmic structure growth, not speed it up
Dark matter is often portrayed as a cosmic loner, interacting with itself and the rest of the universe only through gravity. But what if dark matter particles also exert a hidden force on one another?
Phys.org / Corrected Pantheon+ analysis of supernovae challenges accelerating universe claim
Research led by the Tata Institute of Fundamental Research, Mumbai, along with Professor Subir Sarkar from the University of Oxford, questions the widely accepted argument that the expansion rate of the universe is accelerating ...
Phys.org / Scientists design a clay that can prevent fruits and vegetables from rotting too quickly
Avocados from Chile, bananas from Costa Rica, tomatoes from southern Spain, mangoes from Brazil. A large share of the fruit and vegetables we eat have traveled across the globe before they reach store shelves here at home. ...
Phys.org / Bird-derived gene tool inserts plant DNA 30 times more efficiently than CRISPR
In a rapidly changing climate landscape, the plants we rely on for food, textiles and more face a multitude of challenges, including rising temperatures, drought and disease. Caltech's Gözde Demirer, the Clare Boothe Luce ...
