Hot temperatures can dull blue morpho butterflies
Blue morpho butterflies have captivated the human eye for centuries. We even have one as an emoji on our phones. In a recent experiment, researchers at the Smithsonian Tropical Research Institute (STRI) documented for the first time that hot temperatures during development can reduce the brightness of their iridescence. At hot temperatures, such as those projected in future warming scenarios, the structures responsible for their iridescent color could change enough that common bird predators and other butterflies of the same species would likely see a color change.
The superconducting gap of an ultrathin nickelate defies expectations
Superconductors are materials that carry electrical current with zero resistance below a specific critical temperature. In conventional superconductors, the transition to superconductivity generally occurs at very low temperatures.
Quantum computer microscope is set to significantly improve electron microscopy
Electron microscopes are used wherever particularly small details need to be imaged. But from a strictly physical point of view, every electron in a conventional electron microscope represents a missed opportunity: If all you do is count electrons, any additional quantum information they carry remains unused.

New Monte Carlo method accelerates simulations of densely entangled polymer melts
Long polymer chains are everywhere: in synthetic materials, soft matter, biological systems such as chromosomes, and mathematical models of filaments and knots. When many such chains are densely packed, they form what physicists call a polymer melt. In this crowded environment, each chain is constrained by the others around it. These entanglements are central to the behavior of polymeric materials, but they also make the systems extremely difficult to simulate. As chain length increases, the time needed to obtain a new independent configuration grows very rapidly. For very large systems, conventional simulations can therefore become computationally prohibitive.
Romania has deployed four rock-filled barges in the Danube to redirect scarce river water toward the Cernavod nuclear power plant as severe drought conditions threaten cooling supplies. The intervention produced an unexpected 1.6-inch rise in the river level, despite forecasts predicting an equal decline.
Realistic solid-state model brings fractons in quantum spin liquids closer to detection
Quasiparticles arise from the complex interaction of many particles in solids; for example, we describe lattice vibrations in crystals as phonons. Fractons are exotic quasiparticles that occur at the vertices of magnetic domain walls between different spin orders. What makes them special is that they are virtually immobile and can only be displaced by other fractons. In theory, this limited mobility could be exploited to robustly store quantum information.

Turkey Chokes On $2.5-Bn Russian Trap: Erdogan's Plan To Sell S-400 To UAE Fails, F-35 Door Shut
Trkiye wants back into America's F-35 programme, but a $2.5 billion Russian purchase still stands in the way. Ankara reportedly explored transferring its largely unused S-400 air-defence systems to the UAE, potentially removing the biggest obstacle to an F-35 comeback. That escape route has stalled, with no completed transfer officially confirmed. The UAE faces its own dilemma: it operates US Patriot and THAAD systems, hosts American forces and has itself pursued the F-35. Taking Trkiye's Russian S-400s could import the same security and sanctions concerns that damaged Ankara's relationship with Washington. Russia adds another complication: Moscow has confirmed discussions with Trkiye over the system's fate, while contractual restrictions could affect any onward transfer. Meanwhile, the US State Department says Trkiye still has not met the legal conditions for F-35 access. One Russian weapons purchase continues to haunt Erdogan's stealth-fighter ambitions.
