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.

I was reading Lalo Schifrin's obit; - I hadn't realised he wrote so many of the scores for films I know; I bought his Black Widow album because I liked his music in Bullitt - but Cool Hand Luke, Dirty Harry, Kelly's Heroes, are all ones I grew up on.

These Kids Shoes Have a Hidden AirTag Compartment
Skechers recently started selling a line of kids shoes that have a hidden compartment under the insole for inserting Apple's AirTag item tracker....

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…

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 …
