The Hidden Wheel-Within
There is this old, eternal question: Why don't animals have wheels? In this perspective we show that they actually do. And they do so in a physically extraordinary way -- by combining incompatible elasticity, differential geometry and dissipative self-organization. Nature's wheel -- the ``wheel-within'' -- has been mysteriously concealed in plain sight, yet it spins in virtually every slender-body organism: in falling cats, crocodilians spinning to subdue their prey, rolling fruit-fly larvae, c…

1,000 Swiss glaciers already gone, and the melting is speeding up #Switzerland

1,000 Swiss glaciers already gone, and the melting is speeding up
Swiss glaciers lost nearly 3% of their volume in 2025, following a snow-poor winter and scorching summer heatwaves. The melt has been so extreme that some glaciers lost more than two meters of ice thickness in a single season. Scientists caution that the decline is destabilizing mountains, raising risks of rock and ice avalanches. Long-term monitoring efforts are now more critical than ever.

How researchers tracked the biggest hidden sources of forever chemical pollution in UK rivers
The amount of toxic "forever chemicals" flowing into the River Mersey in north-west England has reached some of the highest levels recorded anywhere in the world.

Wildfire paradox: Decreased burned area but increased human exposure. Study highlights growing risk and importance of proactive mitigation strategies. #climatechange #climatesolutions #climate

Scientists uncover wildfire paradox that’s putting 440 million people in danger
A massive global study uncovered a striking paradox: even as total burned land has dropped by more than a quarter since 2002, human exposure to wildfires has skyrocketed. Africa accounts for a staggering 85% of these exposures, while California stands out as an extreme hotspot despite its relatively small share of burned land. Climate change is fueling more intense fire weather, population growth is pushing communities into fire-prone landscapes, and the overlap between people and flames is gro…

Quantitative Nonlinear Optical Polarimetry with High Spatial Resolution
Nonlinear optical microscopy such as in the optical second-harmonic generation (SHG) modality has become a popular tool today for probing materials in the physical and biological sciences. While imaging and spectroscopy are widely used in the microscopy mode, nonlinear polarimetry, which can shed light on materials' symmetry and microstructure, is relatively underdeveloped. This is partly because quantitative analytical modeling of the optical SHG response for anisotropic crystals and films lar…

What happens when bees can’t buzz right? Nature starts falling apart
High heat and heavy metals dampen a bumblebee’s trademark buzz, threatening pollen release and colony chatter. Tiny sensors captured up-to-400-hertz tremors that falter under environmental stress, raising alarms for ecosystems and sparking ideas for pollination robots.

Machine Learning-Assisted Nano-imaging and Spectroscopy of Phase Coexistence in a Wide-Bandgap Semiconductor
Wide bandgap semiconductors with high room temperature mobilities are promising materials for high-power electronics. Stannate films provide wide bandgaps and optical transparency, although electron-phonon scattering can limit mobilities. In SrSnO3, epitaxial strain engineering stabilizes a high-mobility tetragonal phase at room temperature, resulting in a threefold increase in electron mobility among doped films. However, strain relaxation in thicker films leads to nanotextured coexistence of …
