Under the microscope, they look like they could be from another planet, but these microscopic organisms inhabit the depths of our oceans in nearly infinite numbers.
To begin to identify where, when, and how much oceanic plankton can be found around the globe, a group of international researchers have compiled the first ever global atlas cataloguing marine plankton ranging in size from bacteria to jellyfish. The atlas was published on July 19, 2013, in a special issue of the journal Earth System Science Data. (more…)
Structure of face may help predict expression of prejudice, researchers report
The structure of a man’s face may indicate his tendency to express racially prejudiced beliefs, according to new research published in Psychological Science, a journal of the Association for Psychological Science.
Studies have shown that facial width-to-height ratio (fWHR) is associated with testosterone-related behaviors, which some researchers have linked with aggression. But psychological scientist Eric Hehman of Dartmouth College and colleagues at the University of Delaware speculated that these behaviors may have more to do with social dominance than outright aggression. Hehman conducted the research while he was a graduate student at UD. (more…)
As sea ice in the Arctic continues to shrink during this century, more than two thirds of the area with sufficient snow cover for ringed seals to reproduce also will disappear, challenging their survival, scientists report in a new study.
The ringed seal, currently under consideration for threatened species listing, builds caves to rear its young in snow drifts on sea ice. Snow depths must be on average at least 20 centimeters, or 8 inches, to enable drifts deep enough to support the caves. (more…)
COLUMBIA, Mo. — Freedom of the press is viewed by many as a cornerstone of democracy. But can it actually help improve people’s lives and make them happy? Researchers at the University of Missouri have found that citizens of countries with press freedom tend to be much happier than citizens of countries without free presses. Edson Tandoc, Jr., a doctoral student in the MU School of Journalism, says that press freedom directly predicts life satisfaction across the world.
“We already know that having reliable, objective news sources can benefit democracy, but in this study, we found that press freedom also benefits communities by helping improve the overall quality of life of citizens and, in the process, by also making them happier,” Tandoc said. “People enjoy having an element of choice about where they get their news. Citizens of countries without a free press are forced to rely on the government for information, when what people really want is diversity in content where they are free to get the information they want from the source of their choosing.” (more…)
COLUMBUS, Ohio – Government regulators could more realistically assess the value of improving food safety if they considered the fact that consumers typically want to avoid getting sick – even if it means they have to pay a little extra for safer food, researchers say.
In the world of food regulation, cost-benefit analyses are a primary tool for assessing the societal benefits of mandating more stringent – and more expensive – processing practices. In most cases, regulators determine a dollar value associated with pursuing new rules by estimating how many illnesses and deaths the safer processing would prevent. (more…)
ANN ARBOR, Mich.— Brain scans showing neural reactions to pro-health messages can predict if you’ll keep that resolution to quit smoking more accurately than you yourself can. That’s according to a new study forthcoming in Health Psychology, a peer-reviewed journal.
“We targeted smokers who were already taking action to quit,” said Emily Falk, the lead author of the study and director of the Communication Neuroscience Laboratory at the U-M Institute for Social Research and Department of Communication Studies. “And we found that neural activity can predict behavior change, above and beyond people’s own assessment of how likely they are to succeed.

ANN ARBOR, Mich.—It’s common knowledge that newlyweds who yell or call each other names have a higher chance of getting divorced. But a new University of Michigan study shows that other conflict patterns also predict divorce.
