Staggering extent of human impact on planet revealed in new report

Humanity and the way we feed, fuel and finance our societies and economies is pushing nature and the services that power and sustain us to the brink, according to WWF’s Living Planet Report 2018. The report presents a sobering picture of the impact of human activity on the world’s wildlife, forests, oceans, rivers and climate, underlining the rapidly closing window for action and the urgent need for the global community to collectively rethink and redefine how we value, protect and restore nature.

Researchers find that a speaker’s clearly articulated style can improve a listener’s memory of what was said

Some conversations are forgotten as soon as they are over, while other exchanges may leave lasting imprints. University of Texas at Austin researchers Sandie Keerstock and Rajka Smiljanic want to understand why and how listeners remember some spoken utterances more clearly than others. They’re specifically looking at ways in which clarity of speaking style can affect memory.

Eat your vegetables (and fish): Another reason why they may promote heart health

Elevated levels of trimethylamine N-oxide (TMAO) — a compound linked with the consumption of fish, seafood and a primarily vegetarian diet — may reduce hypertension-related heart disease symptoms. New research in rats finds that low-dose treatment with TMAO reduced heart thickening (cardiac fibrosis) and markers of heart failure in an animal model of hypertension. The study is published ahead of print in the American Journal of Physiology — Heart and Circulatory Physiology and was chosen as an APSselect article for November.

Family tree of 400 million people shows genetics has limited influence on longevity

Although long life tends to run in families, genetics has far less influence on life span than previously thought, according to a new analysis of an aggregated set of family trees of more than 400 million people. The results suggest that the heritability of life span is well below past estimates, which failed to account for our tendency to select partners with similar traits to our own. The research, from Calico Life Sciences and Ancestry, was published in GENETICS, a journal of the Genetics Society of America. Continue reading “Family tree of 400 million people shows genetics has limited influence on longevity” →

Mothers who follow five healthy habits may reduce risk of obesity in children

Children and adolescents whose mothers follow five healthy habits — eating a healthy diet, exercising regularly, keeping a healthy body weight, drinking alcohol in moderation, and not smoking — are 75% less likely to become obese when compared with children of mothers who did not follow any such habits, according to a new study led by Harvard T.H. Chan School of Public Health. When both mother and child adhered to these habits, the risk of obesity was 82% lower compared with mother and children who did not.
