Study shows gypsum wallboard does not keep out carbon monoxide

"Carbon monoxide (CO) poisoning is a significant U.S. health problem, responsible for approximately 500 accidental deaths annually, and a risk of 18 percent to 35 percent for cognitive brain injury 1 year after poisoning. Most morbidity and mortality from CO poisoning is believed to be preventable through public education and CO alarm use. States have been enacting legislation mandating residential CO alarm installation.

Ancient cycads found to be pre-adapted to grow in groves

The ancient cycad lineage has been around since before the age of the dinosaurs. More recently, cycads also co-existed with large herbivorous mammals, such as the ice age megafauna that only went extinct a few tens of thousands of years ago. Cycads that are living today have large, heavy seeds with a fleshy outer coating that suggests they rely on large bodied fruit-eating animals to disperse their seeds. Yet there is little evidence that they are eaten and dispersed by today's larger-bodied animals, such as emus or elephants.

Penn Medicine study shows survivorship care plans empower cancer patients

PHILADELPHIA – In 2005, the Institute of Medicine, surveying the outlook for the growing number of American cancer survivors, first described the idea of a survivorship care plan: a roadmap for the group of patients, today numbering nearly 12 million, who are beginning new lives as cancer survivors.

How untying knots promotes cancer

Researchers have long known that high levels of a specific protein in human cells are linked to tumor growth – but no one has fully understood how.

Now, a groundbreaking discovery by UC Davis graduate student Kateryna Feoktistova and Assistant Professor Christopher Fraser illuminates the way that the protein, eukaryotic initiation factor 4E (eIF4E), acts upon cancer-promoting messenger RNA molecules. When translated, this type of mRNA can trigger the runaway cell replication that results in malignancies.

New explanation for key step in anthrax infection proposed by NIST and USAMRIID

A new hypothesis concerning a crucial step in the anthrax infection process has been advanced by scientists at the National Institute of Standards and Technology (NIST) and the U.S. Army Medical Research Institute for Infectious Diseases (USAMRIID) at Fort Detrick, Md.

Multiple genes manage how people taste sweeteners

Genetics may play a role in how people's taste receptors send signals, leading to a wide spectrum of taste preferences, according to Penn State food scientists. These varied, genetically influenced responses may mean that food and drink companies will need a range of artificial sweeteners to accommodate different consumer tastes.

"Genetic differences lead to differences in how people respond to tastes of foods," said John Hayes, assistant professor, food science and director of the sensory evaluation center.

Chromosome 21 abnormality tells oncologists to treat pediatric ALL more aggressively

A recent study by members of the Children's Oncology Group reports results of a large trial showing that children whose leukemia cells have amplification of a portion of chromosome 21 may require more aggressive treatment for Acute Lymphoblastic Leukemia (ALL) than children without this gene amplification.

Appetite hormone misfires in obese people

Chevy Chase, MD—Glucagon, a hormone involved in regulating appetite, loses its ability to help obese people feel full after a meal, but it continues to suppress hunger pangs in people with type 1 diabetes, according to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).

Gestational diabetes tied to 7-fold increase in sleep apnea risk

Chevy Chase, MD—Women diagnosed with gestational diabetes are nearly seven times more likely to have obstructive sleep apnea than other pregnant women, according to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).

Gestational diabetes causes glucose levels in the bloodstream to rise above normal levels. This form of diabetes occurs during pregnancy, typically in the second trimester. Between four and eight of every 100 pregnant women in the United States develop gestational diabetes.

Social giving makes us happier

People usually feel good when they make a charitable donation, but they feel even better if they make the donation directly to someone they know or in a way that builds social connection. Research to be published in the International Journal of Happiness and Development investigates for the first time how social connection helps turn generous behavior into positive feelings on the part of the donor.

Landfill nation: What makes consumers less likely to recycle?

Consumers are more likely to toss a dented can or a chopped-up piece of paper into the trash than to recycle it, according to a new study in the Journal of Consumer Research that examines recycling habits.

"Although products that have changed shape are still recyclable, the likelihood of a consumer recycling a product or throwing it in the trash can be determined by the extent to which it has been distorted during the consumption process," write authors Remi Trudel (Boston University) and Jennifer J. Argo (University of Alberta).

When do consumers think a freebie is more valuable than a discounted product?

Consumers may value a free gift more than a deeply discounted promotional item, especially if it comes from a prestigious brand, according to a new study in the Journal of Consumer Research.

"Since consumers believe the value of a free product is likely to be consistent with the value of the purchased product, pairing a free product with a high-end product may very well increase perceptions of its value," write authors Mauricio M. Palmeira (Monash University) and Joydeep Srivastava (University of Maryland).

The blushing shopper: Does it matter what else you put in the basket with the anti-gas medication?

Buying certain products can be embarrassing. But a new study in the Journal of Consumer Research says shoppers should make more conscious choices about what to add to their shopping carts to alleviate the embarrassment.

When is controversy (not) good for building product buzz?

A little bit of controversy can be intriguing, but too much turns consumers off, according to a new study in the Journal of Consumer Research.

"Controversial topics can make consumers uncomfortable (since they worry about offending others) and therefore less likely to discuss them. Whether or not consumers are willing to discuss a controversial topic depends on a combination of their level of interest and comfort (or discomfort)," write authors Zoey Chen (Georgia Institute of Technology) and Jonah Berger (Wharton School of the University of Pennsylvania).

Ironic outcomes: Being specific, not flexible, helps consumers achieve their goals

Worried you won't meet your goal? According to a new study in the Journal of Consumer Research, you'll be more likely to succeed if you make specific plans to implement it.

"Consumers believe that flexibility increases their chances of achieving a goal. While this is sometimes true, relatively rigid structures can simplify goal pursuit by eliminating the need to make demanding choices, ultimately making a goal less difficult to achieve," write authors Liyin Jin (Fudan University), Szu-Chi Huang, and Ying Zhang (both University of Texas, Austin).
