In at least one respect, Capuchin monkeys are smarter than humans — they don’t assume a higher price tag means better quality, according to a new Yale study appearing in the open-access journal Frontiers in Psychology.

People consistently tend to confuse the price of a good with its quality. For instance, one study showed that people think a wine labeled with an expensive price tag tastes better than the same wine labeled with a cheaper price tag. In other studies, people thought a painkiller worked better when they paid a higher price for it. (more…)

Yale study: Forest emissions, wildfires explain why ancient Earth was so hot

The release of volatile organic compounds from Earth’s forests and smoke from wildfires 3 million years ago had a far greater impact on global warming than ancient atmospheric levels of carbon dioxide, a new Yale study finds.

The research provides evidence that dynamic atmospheric chemistry played an important role in past warm climates, underscoring the complexity of climate change and the relevance of natural components, according to the authors. They do not address or dispute the significant role in climate change of human-generated CO2 emissions. (more…)

For metals of the smartphone age, no Plan B

Many of the metals needed to feed the surging global demand for high-tech products, from smart phones to solar panels, cannot be replaced, leaving some markets vulnerable if resources become scarce, according to a new Yale study.

In a comprehensive analysis, a team of researchers from the Yale School of Forestry & Environmental Studies (F&ES) evaluated how all 62 metals or metalloids on the periodic table of elements are used in consumer products, and the extent to which each of those metals could be replaced if reserves dwindle or supplies become unreliable.

Despite Efforts for Change, Bangladeshi Women Prefer to Use Pollution-Causing Cookstoves

Women in rural Bangladesh prefer inexpensive, traditional stoves for cooking over modern ones — despite significant health risks, according to a Yale study in the Proceedings of the National Academy of Sciences.

A large majority of respondents (94%) believed that indoor smoke from the traditional stoves is harmful. Still, Bangladeshi women opted for traditional cookstove technology so they could afford basic needs.

“Non-traditional cookstoves might be more successful if they were designed with features valued more highly by users, such as reducing operating costs even if they might not reduce environmental impact,” said Mushfiq Mobarak, a co-author and associate professor of economics at the Yale School of Management.

Children who receive antibiotics within the first six months of life are at a significantly increased risk of developing asthma and allergies by 6 years of age, even without a genetic predisposition, new research by the Yale School of Public Health suggests. The findings are reported online in the American Journal of Epidemiology. (more…)
