Elevated levels of trimethylamine N-oxide (TMAO)—a compound linked with the consumption of 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.

New research reveals that Aspergillus flavus, a fungus that produces carcinogenic aflatoxins that can contaminate seeds and nuts, has a multilegged partner in crime: the navel orangeworm caterpillar, which targets some of the same nut and fruit orchards afflicted by the fungus. Scientists report in the Journal of Chemical Ecology that the two pests work in concert to overcome plant defenses and resist pesticides.

A collective-risk dilemma experiment with members of the public in Barcelona has shown that people are more or less likely to contribute money to fighting climate change depending on their how wealthy they are.

Some of the most useful and versatile materials today are the metal-organic frameworks (MOFs). MOFs are a class of materials demonstrating structural versatility, high porosity, fascinating optical and electronic properties, all of which makes them promising candidates for a variety of applications, including gas capture and separation, sensors, and photocatalysis.

Water shortages are hitting some areas of the world hard, and with increasing global temperatures, more regions may be experiencing drought conditions.
