High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

High expression of the CDK inhibitor p21 correlates with a poor prognosis in non-small cell lung cancer (NSCLC) and, in non-transformed cells, p21 promotes quiescence after replication stress.

- Sodium/glucose cotransporter 2 inhibitors (SGLT2is), such as empagliflozin, show potential heart protection benefits in individuals with or without diabetes and can inhibit a key cardiac sodium current linked to congenital long QT syndrome type 3 (LQT3).
- Researchers used the whole-cell patch-clamp technique to study how empagliflozin affects late sodium current (late I) in various LQT3 mutations of the Nav1.5 channel.
- Empagliflozin specifically inhibited late I in certain mutations without altering channel kinetics, suggesting it could be an effective targeted treatment for patients with LQT3 mutations in the inactivation gate area.
Search for the Exclusive W Boson Hadronic Decays W^{±}→π^{±}γ, W^{±}→K^{±}γ and W^{±}→ρ^{±}γ with the ATLAS Detector.

October 2024
A search for the exclusive hadronic decays W^{±}→π^{±}γ, W^{±}→K^{±}γ, and W^{±}→ρ^{±}γ is performed using up to 140 fb^{-1} of proton-proton collisions recorded with the ATLAS detector at a center-of-mass energy of sqrt[s]=13 TeV. If observed, these rare processes would provide a unique test bench for the quantum chromodynamics factorization formalism used to calculate cross sections at colliders. Additionally, at future colliders, these decays could offer a new way to measure the W boson mass through fully reconstructed decay products.
