Helping others shown to slow cognitive decline
University of Texas at AustinPeer-Reviewed Publication
The new study of more than 30,000 adults in the U.S. found that the rate of cognitive decline associated with aging fell by 15%-20% for people who formally volunteer their services or who help in more informal ways with neighbors, family or friends outside the home on a regular basis. This cognitive benefit was consistently observed when individuals devoted about two to four hours per week to helping others.

PLOSPeer-Reviewed Publication
In a survey study of more than 1,000 U.S. adults who were in committed, heterosexual relationships during the first year of the COVID-19 pandemic, parents were more likely than non-parents to report an increased desire for infidelity since before the pandemic, and were also more likely to report having actually cheated on their partner during the pandemic. Dr. Jessica T. Campbell of Indiana University Bloomington, U.S., and colleagues present these findings in the open-access journal PLOS One on August 13, 2025.

Discovery confirms early species of hominins co-existed in Ethiopia
University of ArkansasPeer-Reviewed Publication
The team found fossils of Homo that confirm the earliest evidence for the human lineage at 2.8 million years ago as well as evidence of Homo at 2.6 million years ago, solidifying the antiquity of Homo. Unexpectedly, the team also found evidence that Homo overlapped at the site with a different type of hominin, Australopithecus, at 2.6 million years ago.
