ANN ARBOR, Mich.—Scientists have discovered a molecular assistant called Spy that helps bacteria excel at producing proteins for medical and industrial purposes.
Bacteria are widely used to manufacture proteins used in medicine and industry, but the bugs often bungle the job. Many proteins fall apart and get cut up inside the bacteria before they can be harvested. Others collapse into useless tangles instead of folding properly, as they must in order to function normally.

GAINESVILLE, Fla. — Taking an unauthorized photo of a patient and posting it on Facebook is a giant no-no for health-care providers, who follow strict federal guidelines protecting patient privacy.
But what if the patient is a little girl in Ecuador receiving a vaccine from an American medical student, who’s in the country on a medical outreach trip? Although taking photos of patients in developing countries and posting them on the Web may not be illegal, it’s not ethical, say researchers from the University of Florida.
It’s long been a common practice for health care providers to snap photos while volunteering their time in developing countries, generally to bring back evidence of the conditions patients face there. But reporting in the Journal of Medical Internet Research, UF College of Medicine researchers say providers should treat patients’ privacy with the same reverence no matter where the care takes place.

Sleeping Beauty’s kingdom was overgrown by vines when she fell into a deep sleep. Researchers at the Smithsonian in Panama and the University of Wisconsin at Milwaukee received more than a million dollars from the U.S. National Science Foundation to discover why real vines are overtaking the American tropics. Data from eight sites show that vines are overgrowing trees in all cases.
“We are witnessing a fundamental structural change in the physical make-up of forests that will have a profound impact on the animals, human communities and businesses that depend on them for their livelihoods,” said Stefan Schnitzer, research associate at the Smithsonian Tropical Research Institute in Panama and associate professor at the University of Wisconsin at Milwaukee.(more…)
When psychotherapy is helping someone get better, what does that change look like in the brain? This was the question a team of Canadian psychological scientists set out to investigate in patients suffering from social anxiety disorder. Their findings are published in Psychological Science, a journal of the Association of Psychological Science.
Social anxiety is a common disorder, marked by overwhelming fears of interacting with others and expectations of being harshly judged. Medication and psychotherapy both help people with the disorder. But research on the neurological effects of psychotherapy has lagged far behind that on medication-induced changes in the brain. (more…)

Washington, D.C.— Chemical compounds called manganites have been studied for many years since the discovery of colossal magnetoresistance, a property that promises important applications in the fields of magnetic sensors, magnetic random access memories and spintronic devices. However, understanding—and ultimately controlling—this effect remains a challenge, because much about manganite physics is still not known. A research team lead by Maria Baldini from Stanford University and Carnegie Geophysical Laboratoryscientists Viktor Struzhkin and Alexander Goncharov has made an important breakthrough in our understanding of the mysterious ways manganites respond when subjected to intense pressure.

*3.2 million-year-old human predecessor had arches in feet*
COLUMBIA, Mo. – Feet arches give humans a spring in their steps, shock absorbing abilities, and stiff platforms to propel themselves forward, allowing them to walk upright consistently. Now, researchers at the University of Missouri and Arizona State University have found proof that arches existed in a predecessor to the human species that lived more than 3 million years ago. This discovery could change scientists’ views of human evolution. The study is being published this week in Science.
Carol Ward, an MU researcher in the Department of Pathology and Anatomical Sciences at the MU School of Medicine, and William Kimbel and Donald Johanson, director and founding director of the Institute of Human Origins at Arizona State University, studied a 3.2 million-year-old fourth metatarsal of Australopithecus afarensis. A team from the Institute of Human Origins and National Museum of Ethiopia led by Kimbel discovered the fossil in Hadar, Ethiopia. The species is often referred to as “Lucy,” the nickname of the most complete fossil skeleton of the species to be discovered. (more…)
