This month, we take a look at three new intriguing findings from researchers across the state. Read below for a look at studies related to speaking in the second-person, male contraceptive, and an “Iron Man” microbe that can extract rust from cobalt.
You’ can be quite persuasive
Sentences that employ the generic or impersonal second-person — where “you” really stands in for “everyone,” as in, “You should read Hour Detroit every month” — tend to resonate better with readers, according to a study recently published in the Proceedings of the National Academy of Sciences and led by University of Michigan psychology and linguistics professor Susan Gelman. Gelman and her co-authors analyzed 1,120 passages in 56 popular books that were highlighted by readers on Kindle, where readers can see what other readers have taken special note of. Passages with the generic “you” were 8.5 times more likely to be highlighted, the researchers found. “This study is a really nice example of how sensitive people are to even a subtle variation in perspective and language,” Gelman says.
The Pill for men in the pipeline?
A pair of Wayne State University scientists landed a $150,000 grant from a nonprofit group known as the Male Contraceptive Initiative to further their research into ways to render sperm infertile. OB-GYN professor Zhibing Zhang and geneticist James Granneman believe they have identified two proteins necessary for sperm to function properly and are investigating ways to interfere with that process so that both men and women can take equal responsibility for preventing unwanted pregnancies. “More and more, men are expressing the desire to participate in contraception with their partners,” says Heather Vahdat, executive director of the North Carolina-based funding group.
‘Iron Man’ cells may help reduce toxic waste
Geobacter, a hardy microbe found in sediment and soil, is capable of extracting rust from cobalt, possibly leading the way to reclaiming the scarce and dangerous metal widely used in high-tech batteries. That’s the findings of a research team led by Michigan State University molecular geneticist Gemma Reguera as published in the journal Frontiers in Microbiology. Reguera likens Geobacter to a Marvel superhero because it removes the rust by taking it on itself “like Iron Man when he puts on the suit.” Reguera next wants to investigate whether the microbe can reclaim cadmium, common in rechargeable batteries and solar cells, which is also polluting landfills and waterways.
