Number of pediatric inpatient psychiatric beds in the U.S. did not increase 2017-2020 despite youth mental health crisis

A study published in JAMA Pediatrics found that US pediatric inpatient psychiatric bed capacity remained steady between 2017 and 2020, despite growing demand. The research also revealed substantial geographic variation in access to inpatient psychiatric care, with rural areas facing a severe shortage of beds.

Expanded child tax credit and food insecurity

A cohort study found that expanded child tax credit (ECTC) enacted substantially lowers food insecurity, whereas ECTC expiration significantly raises it. The monthly payment structure and lack of earnings requirements may play a crucial role in preventing food insecurity.

A galactic conspiracy disproven

An international team of astronomers has disproven a 'conspiracy' that stars and dark matter interact in inexplicable ways. By using advanced modeling techniques, they found that the similarity in galaxy density is due to how astronomers measured and modeled galaxies, rather than an actual interaction between stars and dark matter.
