Putative signature of monogamy
A study suggests a putative gene-expression hallmark common to monogamous male vertebrates of some species, namely cichlid fishes, dendrobatid frogs, passeroid songbirds, common voles, and deer mice, and identifies 24 candidate genes potentially associated with monogamy.

Meaningful life tied to healthy aging
Physical and social well-being in old age are linked to self-assessments of life worth, and a spectrum of behavioral, economic, health, and social variables may influence whether aging individuals believe they are leading meaningful lives.
Research article published in PNAS
“Leading a meaningful life at older ages and its relationship with social engagement, prosperity, health, biology, and time use,” by Andrew Steptoe and Daisy Fancourt.

Reconstructing ocean warming history
A reconstruction of ocean heat storage since 1871 finds that oceans gained heat during the years 1921-1946 at the same rate as since 1990, and the findings on ocean circulation changes can help predict future patterns of warming and sea level rise.
