In the Caribbean, a large majority of people believe that climate change is a danger to themselves and their country. In the United States, only 44 percent do. Yet both places are increasingly vulnerable to powerful hurricanes and other climate-related disasters. Why the difference of opinion? Blame politics, say Vanderbilt University’s Elizabeth Zechmeister and Claire Evans. Their surveys show that because climate change is a partisan issue in the U.S., many don’t see it as a threat.
As drones proliferate, many companies are trying to figure out how they might reinvent package delivery. Researchers Constantine Samaras and Joshuah Stolaroff have analyzed how much energy different freight delivery methods use, and discuss how to use drones to reduce carbon emissions.
Maybe this Valentine’s Day you’re pondering the intangibles about your relationship. Are things going great … or if you’re honest, just kind of OK or not even that well? Psychologist Gary Lewandowski Jr. provides 15 questions, based on relationship science research, that will help you assess whether your partner is the right match for you.
