Just six days ago Republican Sen. Lisa #Murkowski confirmed to NBC News that she won’t vote for Trump in the fall.
The Alaskan’s comments came on the heels of Republican Sen. Mitt #Romney of Utah also ruling out support for his party’s presumptive nominee. Speaking to reporters at the Utah Capitol, Romney said, “I…

Yet another Republican senator says he won’t endorse Trump in 2024
There are now three sitting Republican U.S. senators — and counting — who are not publicly backing Donald Trump's 2024 candidacy. The list might yet grow.

Football
This isn't bad #football from Ireland. Decent effort, and they improved the closing, but they are really lacking quality in midfield.
Very slow, predictable, and conservative passing that leaves the entire attack to the forwards - who arent at that level (few are).

Probabilistic and Maximum Entropy Modeling of Chemical Reaction Systems: Characteristics and Comparisons to Mass Action Kinetic Models
We demonstrate and characterize a first-principles approach to modeling the mass action dynamics of metabolism. Starting from a basic definition of entropy expressed as a multinomial probability density using Boltzmann probabilities with standard chemical potentials, we derive and compare the free energy dissipation and the entropy production rates. We express the relation between the entropy production and the chemical master equation for modeling metabolism, which unifies chemical kinetics an…

Evidence of enhanced thermopower from emergent local moments in flatbands of magic-angle twisted bilayer graphene
Recent experiments on magic-angle twisted bilayer graphene (MATBLG) indicate an unusual coexistence of heavy and light electrons, characteristic of Heavy-Fermion physics. Yet, these experiments lack direct evidence of the existence of local moments associated with the heavy electrons, a key component of Heavy-Fermion physics. Thermopower serves as a sensitive probe for measuring entropy and can, therefore, unveil the presence of local moments by assessing their impact on entropy. In this work, …

GTP before ATP: The energy currency at the origin of genes
Life is an exergonic chemical reaction. Many individual reactions in metabolism entail slightly endergonic processes that are coupled to free energy release, typically as ATP hydrolysis, in order to go forward. ATP is almost always supplied by the rotor-stator ATP synthetase (the ATPase), which harnesses chemiosmotic ion gradients. Because the ATPase is a protein, it arose after the ribosome did. Here we address two questions using comparative physiology: What was the energy currency of metabol…
