(Press-News.org) WASHINGTON, May 14, 2015 -- You might be eating your lunch out of one right now, or eating your lunch with one right now. Polystyrene containers and utensils are found throughout the foodservice industry. The products are recyclable, so why does so much of this material end up in a landfill, and why have so many cities banned its use? Sophia Cai has the answers in this week's Speaking of Chemistry.

Stanford University scientists have solved a long-standing mystery about methanogens, unique microorganisms that transform electricity and carbon dioxide into methane.
In a new study, the Stanford team demonstrates for the first time how methanogens obtain electrons from solid surfaces. The discovery could help scientists design electrodes for microbial "factories" that produce methane gas and other compounds sustainably.
"There are several hypotheses to explain how electrons get from an electrode into a methanogen cell," said Stanford postdoctoral scholar Jörg ...

ANN ARBOR, Mich. -- Parents often bring their school-aged children to check-ups or sick visits armed with questions. What should he put on that rash? What about her cough that won't go away?
But when children's temper tantrums or mood swings are beyond the norm, or they are overwhelmed by homework organization, do parents speak up?
Today's University of Michigan C.S. Mott Children's Hospital National Poll on Children's Health finds that many parents of children age 5-17 wouldn't discuss behavioral or emotional issues that could be signs of potential health problems ...

Social media messaging, screening and interventions offer new tools to help colleges prevent and reduce excessive drinking, according to a report authored by a Boston University School of Public Health researcher, working with a group of experts.
The report recommends that colleges use mobile technology to address heavy drinking on campuses as part of a comprehensive approach that includes consistent enforcement of drinking age and consumption laws, trained intervention specialists, and a crackdown on low-priced serving methods such as kegs and "happy hours."
"Low prices ...

New research finds that misdiagnoses lead to increased risk of incorrect antibiotic use, threatening patient outcomes and antimicrobial efficacy, while increasing healthcare costs. The study was published online today in Infection Control & Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America.
"Antibiotic therapies are used for approximately 56 percent of inpatients in U.S. hospitals, but are found to be inappropriate in nearly half of these cases, and many of these failures are connected with inaccurate diagnoses," said Greg Filice, ...

Practice may not make perfect, but visualization might. New research shows that people who imagined a visual target before having to pick it out of a group of distracting items were faster at finding the target than those who did an actual practice run beforehand. The findings are published in Psychological Science, a journal of the Association for Psychological Science.
"The idea that we can train our brains to work better is all the rage across society, but our research suggests that the human brain may benefit as much, or even more, from imagining performing a task, ...

HANOVER, N.H. - Opening the way for new applications of smart devices, Dartmouth researchers have created the first form of real-time communication that allows screens and cameras to talk to each other without the user knowing it.
Using off-the-shelf smart devices, the new system supports an unobtrusive, flexible and lightweight communication channel between screens (of TVs, laptops, tablets, smartphones and other electronic devices) and cameras. The system, called HiLight, will enable new context-aware applications for smart devices. Such applications include smart glasses ...

Singapore, 18 May 2015 - A seven-year scientific study has revealed that microbial communities in urban waterways has the potential to play an important role in cleansing Singapore's waterways and also act as raw water quality indicators.
The study found that canals designed to channel rainwater host microbial communities that could remove and neutralise organic pollutants in raw water. These organic pollutants are currently at trace levels in raw water - well below the United States-Environmental Protection Agency (US-EPA) drinking water standards - which is removed ...

In a letter to the Medical Journal of Australia published today, a Monash University-led team is asking for hepatitis C virus patients to gain improved access to drugs to prevent liver related deaths.
Hepatitis C virus (HCV) infection is a major public health burden in Australia, with estimates of 230,000 people chronically infected.
The research team are calling for the government to subsidise a new therapy which has high cure rates, known as direct acting antiviral (DAA) therapy.
Monash University Professor William Sievert said a delay in access to DAA treatment ...

Washington, DC (May 18, 2015) -- Patients faced with a choice of surgical options want to engage their physicians and take a more active role in decision-making, according to a study (abstract 567) released at Digestive Disease Week® (DDW) 2015. Further, those physicians must provide better support tools to help patients participate in the decision-making process. The study found that patients consult multiple sources (Internet, family, friends, doctors, etc.) and say that while doctors provide the most believable information, it was also the least helpful.
"In this ...

The historical past is important when we seek to understand environmental conditions as they are today and predict how these might change in the future. This is according to researchers from Umeå University, whose analyses of lake-sediment records show how lake-water carbon concentrations have varied depending on long-term natural dynamics over thousands of years, but also in response to human impacts over the past several hundred years. The study has been published in PNAS (the Proceedings of the National Academy of Sciences).
Environmental monitoring programmes ...
