Ecological forces structure your body’s personal mix of microbes

Environmental conditions have a much stronger influence on the mix of microbes living in various parts of your body than does competition between species. Instead of excluding each other, microbes that fiercely compete for similar resources are more likely to cohabit in the same individual.

This phenomenon was discovered in a recent study of the human microbiome – the vast collection of our resident bacteria, fungi, and other tiny organisms. (more…)

Americans Have Worse Health than People in Other High-Income Countries

WASHINGTON — On average, Americans die sooner and experience higher rates of disease and injury than people in other high-income countries, says a new report from the National Research Council and Institute of Medicine.

The report finds that this health disadvantage exists at all ages from birth to age 75 and that even advantaged Americans—those who have health insurance, college educations, higher incomes and healthy behaviors—appear to be sicker than their peers in other rich nations. (more…)

Global Research Team Discovers New Alzheimer’s Risk Gene

Scientists have discovered a rare genetic mutation that increases the risk of Alzheimer’s disease.

The international team, led by researchers at the UCL Institute of Neurology, studied data from more than 25,000 people and found a link between a rare variant of the TREM2 gene – which is known to play a role in the immune system – and a higher risk of Alzheimer’s.

The paper, which is published in the New England Journal of Medicine, has major implications for our understanding of the causes of Alzheimer’s and the authors believe it is potentially the most influential gene discovery for the disease in the last two decades. (more…)

Scientists from UCLA, Israel’s Technion Uncover Brain’s Code for Pronouncing Vowels

Discovery may hold key to restoring speech after paralysis

Diagnosed with Lou Gehrig’s disease at 21, British physicist Stephen Hawking, now 70, relies on a computerized device to speak. Engineers are investigating the use of brainwaves to create a new form of communication for Hawking and other people suffering from paralysis.

—Daily Mail (U.K.)


Scientists at UCLA and the Technion, Israel’s Institute of Technology, have unraveled how our brain cells encode the pronunciation of individual vowels in speech.

Published in the Aug. 21 edition of the journal Nature Communications, the discovery could lead to new technology that verbalizes the unspoken words of people paralyzed by injury or disease. (more…)

Tilting Cars on the Assembly Line: A New Angle on Protecting Autoworkers

COLUMBUS, Ohio – Letting autoworkers sit while they reach into a car’s interior could help prevent shoulder and back strain – but another solution might be to tilt the entire car so that workers can stand up.

That’s the finding of two recent studies, which tested two ways to protect autoworkers from injury.

Sitting on a cantilevered chair reduced the stress on the workers’ backs and shoulders for three common installation tasks. But a different strategy – tilting a car sideways on a carriage so that workers could access the interior while standing – reduced the stress for nine different tasks. (more…)

Female and Younger Athletes Take Longer to Overcome Concussions

EAST LANSING, Mich. — New research out of Michigan State University reveals female athletes and younger athletes take longer to recover from concussions, findings that call for physicians and athletic trainers to take sex and age into account when dealing with the injury.

The study, led by Tracey Covassin of MSU’s Department of Kinesiology, found females performed worse than males on visual memory tests and reported more symptoms postconcussion.

Additionally, high school athletes performed worse than college athletes on verbal and visual memory tests, and some of the younger athletes still were impaired up to two weeks after their injuries. (more…)

Study Shows Benefit of Gun Cabinets in Homes in Alaskan Villages

Installing a gun cabinet dramatically reduces unlocked guns and ammunition in the home, according to a study in rural Alaska villages where the residents are primarily Alaska Native people. Dr. David Grossman, Group Health Research Institute senior investigator and UW professor of health services, led the research published in the American Journal of Public Health March 8. Grossman is also a pediatrician and medical director for preventive care at Group Health.

Grossman’s research team included representatives from the Alaska Native Tribal Health Consortium, two Native health organizations (Yukon Kuskokwim Health Corporation and Bristol Bay Area Health Corporation), village tribal governments and faculty from UW Medicine’s Harborview Injury Prevention and Research Center. They identified households in six Alaska Native villages in the Bristol Bay and Yukon Kuskokwin Delta area of western Alaska. (more…)

Markerless Motion Capture Offers A New Angle On Tennis Injuries

COLUMBUS, Ohio – A new approach to motion capture technology is offering fresh insights into tennis injuries – and orthopedic injuries in general.

Researchers studied three types of tennis serves, and identified one in particular, called a “kick” serve, which creates the highest potential for shoulder injury. (more…)
