Nighttime smartphone use zaps workers’ energy
Using a smartphone to cram in more work at night results in less work the next day, indicates new research co-authored by a Michigan State University business scholar.
In a pair of studies surveying a broad spectrum of U.S. workers, Russell Johnson and colleagues found that people who monitored their smart phones for business purposes after 9 p.m. were more tired and were less engaged the following day on the job. (more…)
Southwest Regional Warming Likely Cause of Pinyon Pine Cone Decline, Says CU Study
Creeping climate change in the Southwest appears to be having a negative effect on pinyon pine reproduction, a finding with implications for wildlife species sharing the same woodland ecosystems, says a University of Colorado Boulder-led study.
The new study showed that pinyon pine seed cone production declined by an average of about 40 percent at nine study sites in New Mexico and northwestern Oklahoma over the past four decades, said CU-Boulder doctoral student Miranda Redmond, who led the study. The biggest declines in pinyon pine seed cone reproduction were at the higher elevation research sites experiencing more dramatic warming relative to lower elevations, said Redmond of CU’s ecology and evolutionary biology department.

Father’s Death Affects Early Adolescents’ Futures in Developing World, Says MU Anthropologist
Knowledge of effects could lead to better assistance for youths
COLUMBIA, Mo. – A father’s death can have long-term effects on a child’s later success in life and can be particularly harmful if the father passes away during a child’s late childhood or early adolescence, according to new research by a University of Missouri anthropologist. Recognizing the impact that a father’s death can have on adolescents could lead to improved counseling and assistance programs, especially for needy families in the developing world.
“Certain negative effects of a father’s death can’t be compensated for by the mother or other relatives,” said Mary Shenk, assistant professor of anthropology in MU’s College of Arts and Science. “The loss of a father can result in lower adult living standards for the bereaved children. Not only is a child emotionally affected, but the lack of a father’s earning power can cause children to get married younger or drop out of school in order to work.” (more…)
Ecologists Shed New Light on Effects of Light Pollution on Wildlife
Light pollution is often associated with negative effects on wildlife. Now, ecologists have found that by mimicking a perpetual full moon, the gas flares and electrical lighting along Scotland’s Forth estuary are helping shorebirds stock up on more food during the winter to fuel their spring migration.
The research is the first to use night-time light data from US military satellites to study animal behaviour.
Coasts and estuaries are among the most rapidly developing areas on Earth. Night-time satellite images of the planet show that except Antarctica, continents are ringed with halos of brightly-lit human development. But coasts are also key wildlife sites. Every year, millions of waterbirds arrive from the Arctic to overwinter on UK coasts, yet scientists remain largely in the dark about how these birds respond to the bright lights of coastal cities and industry.

Sharks: Bad Creatures or Bad Image?
EAST LANSING, Mich. — Historically, the media have been particularly harsh to sharks, and it’s affecting their survival.
The results of a Michigan State University study, appearing in the current issue of the journal Conservation Biology, reviewed worldwide media coverage of sharks – and the majority isn’t good.
Australian and U.S. news articles were more likely to focus on negative reports featuring sharks and shark attacks rather than conservation efforts. Allowing such articles to dominate the overall news coverage diverts attention from key issues, such as shark populations are declining worldwide and many species are facing extinction, said Meredith Gore, MSU assistant professor of fisheries and wildlife and the School of Criminal Justice.

The Bright Side of Death: Awareness of Mortality Can Result in Positive Behaviors, Say MU Researchers
COLUMBIA, Mo. — Contemplating death doesn’t necessarily lead to morose despondency, fear, aggression or other negative behaviors, as previous research has suggested. Following a review of dozens of studies, University of Missouri researchers found that thoughts of mortality can lead to decreased militaristic attitudes, better health decisions, increased altruism and helpfulness, and reduced divorce rates.
“According to terror management theory, people deal with their awareness of mortality by upholding cultural beliefs and seeking to become part of something larger and more enduring than themselves, such as nations or religions,” said Jamie Arndt, study co-author and professor of psychological sciences. “Depending on how that manifests itself, positive outcomes can be the result.” (more…)
Stress About Wife’s Breast Cancer Can Harm A Man’s Health
COLUMBUS, Ohio – Caring for a wife with breast cancer can have a measurable negative effect on men’s health, even years after the cancer diagnosis and completion of treatment, according to recent research.
Men who reported the highest levels of stress in relation to their wives’ cancer were at the highest risk for physical symptoms and weaker immune responses, the study showed. (more…)
