The gut bacteria of honey bees have acquired several genes that confer resistance to tetracycline, a direct result of more than five decades of use of antibiotics by American beekeepers and a potential health hazard for bee colonies, a new study by Yale University researchers show.
The genetic analysis of the gut bacteria, which are believed to help in bees’ digestion and ability to ward off parasites, suggests changing antibiotic use by beekeepers might be one factor in the mysterious colony collapse disorder afflicting bee populations. (more…)
What are the key ingredients to raising successful, self-sufficient offspring? A new life sciences study using 14 years of data on gray wolves in Yellowstone National Park indicates that cooperative group behavior and a mother’s weight are crucial.
“A female’s body weight is key in the survival of her offspring, and cooperation in the protection and feeding of young pups pays off in terms of the production of offspring,” said Robert Wayne, a professor of ecology and evolutionary biology at UCLA and co-author of the new research, published this week in the online edition of the Journal of Animal Ecology.

EAST LANSING, Mich. — Increasingly, U.S. firms are moving or considering moving their manufacturing operations back to domestic soil from overseas, finds a new study co-authored by a Michigan State University supply chain expert.
Fueling the trend are rising labor costs in emerging countries, high oil prices and increasing transportation costs, global risks such as political instability and other factors, said Tobias Schoenherr.
“Going overseas is not the panacea that it was thought of just a decade or so ago,” said Schoenherr, assistant professor in MSU’s top-ranked Department of Supply Chain Management. “Companies have realized the challenges and thus are moving back to the United States.” (more…)
International team of scientists finds adaptations to stress in oyster genome
When it comes to stress, oysters know how to deal. The tough-shelled mollusks can survive temperature fluctuations, toxic metals and exposure to air, and a new study of their genetic makeup is helping to explain how.
An international team of scientists, including the University of Delaware’s Patrick M. Gaffney, professor of marine biosciences, sequenced the genome of the Pacific oyster, Crassostrea gigas, in a Naturepaper published on Sept. 19. (more…)
Whether you’re a new blogger trying to gain some recognition for your blog or a seasoned veteran looking for something new to do, guest posting for other bloggers is one of the best things you can do to both expand your blog and improve your writing. It can be a little intimidating at first, trying to reach out to other bloggers and pitch topic ideas or submit articles, however there’s a lot to be gained from doing so.
1. Exposure: Writing for other blogs, big or small, exposes your writing to an entirely new audience. This is one of the major factors in helping your blog grow, because when someone reads your guest post and appreciates your writing style or the information you shared they will almost always click over to your blog to see what else you have to offer.
2. Links: Backlinks on other websites are what every blogger works so hard to gain because they offer another way for people to find your blog. Since most bloggers will allow their guest posters to put a link in the byline to their blog, it’s the perfect way for you to obtain a new link on the web. (more…)
Researchers from North Carolina State University have developed a new method for forecasting seasonal hurricane activity that is 15 percent more accurate than previous techniques.
“This approach should give policymakers more reliable information than current state-of-the-art methods,” says Dr. Nagiza Samatova, an associate professor of computer science at NC State and co-author of a paper describing the work. “This will hopefully give them more confidence in planning for the hurricane season.” (more…)
A new study finds that relatively early into tobacco addiction, teens experience many of the same negative psychological effects during abstinence as adults do, with a couple of exceptions. The data can inform efforts to improve the efficacy of quitting and withdrawal treatment programs.
PROVIDENCE, R.I. [Brown University] — Abstinence from smoking seems to affect teens differently than adults in a couple of ways, but a new study provides evidence that most of the psychological difficulties of quitting are as strong for relatively new, young smokers as they are for adults who have been smoking much longer.
“Adolescents are showing — even relatively early in the dependence process — significant, strong, negative effects just after acute abstinence from smoking,” said L. Cinnamon Bidwell, assistant professor (research) in psychiatry and human behavior at the Center for Alcohol and Addiction Studies. “Our study shows what those specific effects are. We chose a broad array” of factors to study. (more…)
EAST LANSING, Mich. — Witch hunts are common and sometimes deadly in the tea plantations of Jalpaiguri, India. But a surprising source – small groups of women who meet through a government loan program – has achieved some success in preventing the longstanding practice, a Michigan State University sociologist found.
Soma Chaudhuri spent seven months studying witch hunts in her native India and discovered that the economic self-help groups have made it part of their agenda to defend their fellow plantation workers against the hunts. (more…)
