The near deadlock on land has led to an alternative Ukrainian effort to win by economic means.
While Russia has stepped up bombing of Ukraine’s energy infrastructure
and residents of the country’s cities endure electricity outages,
Kyiv is still able to get power to the front,
its defences not obviously impaired.
And despite the regularity of Russian drone and missile attacks,
civilian morale appears not to have been significantly affected.

I was wondering when the question of international gold storage in New York would come up.

Massachusetts is about to see major savings from clean energy. A new analysis shows the state's SMART 3.0 solar-plus-storage program could save ratepayers $313 million annually by 2030.
The key? Pushing out inefficient natural gas plants, cutting reliance on fossil fuels during winter, and slashing 1.6 million metric tons of CO2 per year.

I consider Peter #Thiel to be a power-hungry and ruthless egomaniac with a religious streak, which he tactically brings to the fore in order to hide his true character. Thiel himself is a great danger to peace and freedom and to a future in which all people and all of creation can participate.
Thiel is a negative #monomaniac

Abstract: Light carrying transverse orbital angular momentum (T-OAM) in the form of spatiotemporal optical vortices (STOVs) is opening new degrees of freedom for structured light manipulation. Such spatiotemporal wavepackets hold significant potential for optical trapping, analog optical computing, studying photonic symmetry and topology, among others. Up to now, synthesizing of such vortices is limited in one dimension, either in temporal or spatial domain. In this work, we propose and experimentally demonstrate a two-dimensional flexible mesh of spatiotemporal optical vortices (M-STOV) with programmable intensity nulls, and analyze their diffraction patterns for detection. Furthermore, we extend the spectral range of M-STOV via second-harmonic generation while examining the transfer of OAM in this nonlinear process. This study establishes a foundational framework for designing higher dimensional spatiotemporal vortex fields and promises a high-capacity information carrier based on ST optical vortices.

Whitehouse propaganda minister Karoline Leavitt insisted,
“Everything I’m telling you is the truth backed by real, factual data,
and you just don’t want to report on it ’cause you want to push untrue narratives about the president.'”
The “real, factual data” that underpinned Leavitt’s statement was specious at best.
The actual inflation rate for September was 3%,
