Late in 2024, Elon Musk endorsed Germany’s far-right Alternative für Deutschland. We document that after this, Tesla sales rose by up to 30 percent in right-leaning districts relative to left-leaning ones [..] Divestment in second-hand markets shows no partisan differences, consistent with resale requiring a larger identity cost from Tesla’s image shock than non-purchase. Our lower bound-estimate for the overall loss in Tesla sales is [..] worth at least €241 million."

Abstract: Why kinetically stable oil droplets in water spontaneously acquire a negative charge remains one of the most vigorously debated questions in interfacial science. Here, we combine neural-network based deep potential molecular dynamics with a data-driven and information theory approach to probe the real-space electron density at an extended decane-water interface. While decane-water clusters show nearly symmetric forward and backward charge transfer (CT) and thus negligible net CT, the extended interface displays a systematic electronic asymmetry, yielding a net CT from water to the hydrocarbon phase producing an average surface charge density of $\sim0.006~e^{-}\,\mathrm{nm}^{-2}$ on the oil phase. This imbalance is accompanied by much larger intra-phase self-polarization, particularly within the hydrocarbon phase, demonstrating that collective many-body polarization dominates the interfacial electronic response. Structural analysis reveals an asymmetry between forward C--H$\cdots$O and backward O--H$\cdots$C motifs, providing a microscopic origin for a net CT from one phase to the other. Curiously, both the water O--H and decane C--H covalent bonds incur subtle contractions which originate from a response to the charge-separation layers at the interface. These features are fully consistent with the weak improper hydrogen-bonds forming at the oil-water interface that results in blue-shifts of the C-H modes.

Iran and Russia have a large interest in increasing polarization in Europe and will support extremists that are willing to attack Muslim or Jewish targets in Europe. Fear, distrust is in their interest. The US also has the explicit intention to weaken the EU. Dangerous times.

Even now, America can’t rally.
What has Trump done?
These are supposed to be the most American of days.
The United States had a historic showing at the Winter Olympics.
This year is the 250th anniversary of the nation’s founding.
And we are at war.
In normal times, each would summon national pride and unity.
But they’re happening together — the rally-around-the-flag effect should be supercharged.
It’s not.

Good to see the NDP in second with 18.9% of the vote in one of the by-elections last night.
The polarization between the Bloc and Liberals in Terrebonne is pretty stunning but at least there was a clear winner this time! The CPC got just 3% and the other three barely added up to 1% there!
The Toronto ridings were at least a little more spread out, but both remain solid Liberal seats with more than 60% of the vote.
I don’t like how the Liberals gained their majority, a first in Canadian history… but that’s the hand we are dealt. Time to work at it.
