nTIDE December 2023 Jobs Report: People with disabilities maintain strong employment levels through end of year, staying at historic highs

In December 2023, people with disabilities in the US maintained their employment-to-population ratio near historic highs. The labor force participation rate for individuals with disabilities also remained steady around 40% throughout the last half of 2023. In contrast, those without disabilities experienced slight declines in both rates.

Ancestors of primates lived in pairs

A study published in PNAS found that 70 million years ago, primates' ancestors mostly lived in pairs, with only 15% opting for solitary lifestyles. This flexible pair-living ancestor likely offered benefits such as easier reproduction and thermoregulation.

Asbestos: the size and shape of inhaled nanofibers could be exclusively responsible for the development of pulmonary fibrosis

Research reveals that inhaling asbestos or similar nanofibers can lead to pulmonary fibrosis due to their inability to be fully encapsulated by macrophages. The study found that fibers over 15 microns in length cause leaked secretions harmful to alveolar walls, leading to repeated pulmonary lesions and potential fibroma development.
