This Letter presents a search for highly ionizing magnetic monopoles in 262 μb^{-1} of ultraperipheral Pb+Pb collision data at sqrt[s_{NN}]=5.36 TeV collected by the ATLAS detector at the LHC. A new methodology that exploits the properties of clusters of hits reconstructed in the innermost silicon detector layers is introduced to study highly ionizing particles in heavy-ion data.

Limited data, however, exist on the associations with mercury exposure, particularly early in life.
Objective: We examined the association between prenatal mercury (Hg) exposure and TL and mtDNAcn in 1,145 Seychelles children, characterized by a fish-rich diet.
Z boson events at the Large Hadron Collider can be selected with high purity and are sensitive to a diverse range of QCD phenomena. As a result, these events are often used to probe the nature of the strong force, improve Monte Carlo event generators, and search for deviations from standard model predictions. All previous measurements of Z boson production characterize the event properties using a small number of observables and present the results as differential cross sections in predetermined bins.

Objective: To determine the associations between maternal fish intake (a rich source of the n-3 PUFAs), maternal or cord PUFAs with the prevalence of childhood asthma in a high fish-eating population.
Methods: We examined these associations between fish intake and PUFA concentrations with childhood asthma prevalence in the Seychelles Child Development Study Nutrition Cohort 2, a large observational study in a high fish-eating population.
