Honeybee hive sealant promotes hair growth in mice

2014-12-10
(Press-News.org) Hair loss can be devastating for the millions of men and women who experience it. Now scientists are reporting that a substance from honeybee hives might contain clues for developing a potential new therapy. They found that the material, called propolis, encouraged hair growth in mice. The study appears in ACS' Journal of Agricultural and Food Chemistry.

Ken Kobayashi and colleagues note that propolis is a resin-like material that honeybees use to seal small gaps in their hives. Not only does it work as a physical barrier, but it also contains active compounds that fight fungal and bacterial invasions. People from ancient times had noticed propolis' special properties and used it to treat tumors, inflammation and wounds. More recently, research has shown that the substance promotes the growth of certain cells involved in hair growth though no one had yet tested whether that in turn would result in new locks. Kobayashi's team wanted to find out.

When the researchers tested propolis on mice that had been shaved or waxed, the mice that received the treatment regrew their fur faster than those that didn't. The scientists also noticed that after the topical application, the number of special cells involved in the process of growing hair increased. Although they tried the material on mice that could grow fur rather than balding mice, the researchers note that hair loss conditions often result from abnormal inflammation. Propolis contains anti-inflammatory compounds, so they expect it could help treat balding conditions.

They add that further testing is needed to see if the beehive material affects human hair follicles.

Georgia State/CDC study: US taxpayers bear financial burden of smoking-related disease

2014-12-10
Cigarette smoking generates as much as $170 billion in annual health care spending in the United States, according to a new study co-authored by researchers at Georgia State University's School of Public Health, the Centers for Disease Control and Prevention (CDC) and RTI International. Dr. Terry F. Pechacek, a professor of health management and policy at Georgia State, was the senior author of the study, "Annual Healthcare Spending Attributable to Cigarette Smoking (An Update)," which was published Wednesday by the American Journal of Preventive Medicine. The study ...

New 'electronic skin' for prosthetics, robotics detects pressure from different directions

2014-12-10
Touch can be a subtle sense, but it communicates quickly whether something in our hands is slipping, for example, so we can tighten our grip. For the first time, scientists report the development of a stretchable "electronic skin" closely modeled after our own that can detect not just pressure, but also what direction it's coming from. The study on the advance, which could have applications for prosthetics and robotics, appears in the journal ACS Nano. Hyunhyub Ko and colleagues explain that electronic skins are flexible, film-like devices designed to detect pressure, ...

CWRU nursing school develops how-to exercise pamphlet for people with MS

2014-12-10
Fatigue and pain, along with other symptoms, prevent many people with multiple sclerosis (MS) from exercising. But a new how-to guide for a home-based exercise program, tested by researchers at Case Western Reserve University's nursing school and the Lerner Research Institute at the Cleveland Clinic, offers a way for people with MS to stay more physically active. The researchers developed a 24-week exercise program based on a series of pamphlets with varying levels of difficulty. The program helps inactive individuals start at a lower, shorter level of activity and gradually ...

'Smart windows' have potential to keep heat out and save energy

2014-12-10
Windows allow brilliant natural light to stream into homes and buildings. Along with light comes heat that, in warm weather, we often counter with energy-consuming air conditioning. Now scientists are developing a new kind of "smart window" that can block out heat when the outside temperatures rise. The advance, reported in ACS' journal Industrial & Engineering Chemistry Research, could one day help consumers better conserve energy on hot days and reduce electric bills. Xuhong Guo, Kaimin Chen, Yanfeng Gao and colleagues explain that researchers are pursuing smart windows ...

Theory details how 'hot' monomers affect thin-film formation

Theory details how hot monomers affect thin-film formation
2014-12-10
HOUSTON - (Dec. 10, 2014) - Like a baseball player sliding into third, a hot monomer skids in a straight line along a cold surface until it's safely among its fellow molecules. This is not what usually happens when scientists assemble monomers to make thin films for next-generation electronics, but the details remained a puzzle until a team led by Rice University got involved. Monomers are organic molecules that, in this application, form clusters and eventually complete layers. Researchers at Rice and the University of Maryland led by Rice theoretical physicist ...

New insight into cancer defense mechanism

2014-12-10
A Danish Research Team identified a molecular mechanism that ensures that when cells divide, the genomic material passes correctly to the resulting daughter cells: "The process, known as chromosome segregation, is vitally important because incorrect passage of the genomic material makes cells prone to develop into cancer cells," says Jakob Nilsson, associate professor at the Novo Nordisk Foundation Center for Protein Research. The new discovery depends on a protein called BubR1 which if mutated can cause cancer. The results have just been published in the scientific ...

How long can Ebola live?

2014-12-10
The Ebola virus travels from person to person through direct contact with infected body fluids. But how long can the virus survive on glass surfaces or countertops? How long can it live in wastewater when liquid wastes from a patient end up in the sewage system? In an article published Dec. 9 in the journal Environmental Science & Technology Letters, Kyle Bibby of the University of Pittsburgh reviews the latest research to find answers to these questions. He and his co-investigators didn't find many answers. "The World Health Organization has been saying you can put ...

New study measures methane emissions from natural gas production and offers insights into two large sources

2014-12-10
A team of researchers from the Cockrell School of Engineering at The University of Texas at Austin and environmental testing firm URS reports that a small subset of natural gas wells are responsible for the majority of methane emissions from two major sources -- liquid unloadings and pneumatic controller equipment -- at natural gas production sites. With natural gas production in the United States expected to continue to increase during the next few decades, there is a need for a better understanding of methane emissions during natural gas production. The study team ...

Study examines effects of family-friendly workplace policies

Study examines effects of family-friendly workplace policies
2014-12-10
A happy worker is a productive worker. That adage may be true, according to a new study from The University of Texas at Dallas. Two UT Dallas public affairs researchers found that family-friendly policies are beneficial for increasing productivity of employees in public organizations, and the authors said the finding likely lends itself to job satisfaction and commitment. The study, published in the Public Personnel Management, investigated the effects of family-friendly human resources policies in public organizations. Using the Korea Workplace Panel Survey data from ...

Students design workstations that accommodate groups and individual

2014-12-10
New school and office workspace designs created by a group of Penn State engineering students are intended to allow users to share space and materials while maintaining their own work areas -- a dual purpose the researchers say has been neglected. The research began in 2010 as a class project, according to Joseph M. Mahoney, former Penn State graduate student, now assistant professor of mechanical engineering, Penn State, Berks. "There's a lot of interest from an ergonomics perspective and workplace efficiency perspective of designing workstations for single users," Mahoney ...
