Now, a study hints at why we get so unraveled after hours of hard mental labor: a toxic buildup of glutamate, the brain’s most abundant chemical signal.

New records of < em > Triatoma huehuetenanguensis < /em > in an urban area of Southwest Mexico
J Vector Borne Dis. 2022 Jan-Mar;59(1):86-90. doi: 10.4103/0972-9062.331410.ABSTRACTThe recently described Triatoma huehuetenanguensis, has been reported in Mexico, Guatemala, Belize and Honduras. In Mexico, the species has been collected primarily in rural areas; it has the potential to colonize human dwellings, however, its contribution to Chagas outbreaks remains unclear. In 2021, T. huehuetenanguensis was first observed at Tuxtla Gutierrez city, Chiapas; then a collection for the species was performed. A total of 308 houses were inspected in the intra and peridomestic structures. Only 3 houses (0.97%) were infested. Tr...
