Bioluminescence may play a key role in successful foraging for southern elephant seals, a deep-sea predator, according to research published Aug. 29 in the open access journal PLOS ONE. The authors of the study, led by Jade Vacquié-Garcia, monitored the diving behaviour of four female southern elephant seals in the southern Indian Ocean that were also equipped with light detectors. The researchers found that increased bioluminescence was correlated with higher foraging...

Patients with anorexia have trouble accurately judging their own body size, but not others', according to research published Aug. 22 in the open access journal PLOS ONE. In the study, led by Dewi Guardia of the University Hospital of Lille in France, 25 patients with anorexia and 25 controls were shown a door-like aperture and asked to judge whether or not it was wide enough for them to pass through, or for another person present in the room to pass through. In previous similar...

Two parasitic wasp species show similar memory consolidation patterns in response to rewards of different quality, providing evidence that the reward value affects the type of memory that is consolidated. The full results are reported Aug. 22 in the open access journal PLOS ONE. The researchers, led by Marjolein Kruidhof of the Netherlands Institute of Ecology, tested how wasps store scents associated with situations of low reward (egg-laying into a inferior-quality host species that lays...

Approximately one in five prescriptions to elderly people is inappropriate, according to a study published Aug. 22 in the open access journal PLOS ONE. The authors of the study, led by Dedan Opondo of the Academic Medical Center in Amsterdam, conducted a systematic review of English-language studies of medication use in the elderly and found that the median rate of inappropriate prescriptions was 20.5%. Some of the medications with the highest rates of inappropriate use were the...

Managers and non-managers show distinctly different brain activation patterns when making decisions, according to research published Aug. 22 in the open access journal PLOS ONE. The authors of the study, led by Svenja Caspers of the Institute of Neuroscience and Medicine, Research Centre Jülich in Germany, used functional MR imaging to track the decision making process for managers and non-managers. Subjects were required to perform equally repetitive decisions, one form of...

Johns Hopkins scientists have developed a reliable method to turn the clock back on blood cells, restoring them to a primitive stem cell state from which they can then develop into any other type of cell in the body. The work, described in the Aug. 8 issue of the journal Public Library of Science (PLoS), is "Chapter Two" in an ongoing effort to efficiently and consistently convert adult blood cells into stem cells that are highly qualified for clinical and research use in place of human...

Specific gut bacteria may be associated with metabolic syndrome traits, as determined by a study of Pennsylvania's Old Order Amish population. The full results are reported on Aug. 15 in the open access journal PLoS ONE. The researchers, led by Claire M. Fraser of the Institute for Genome Sciences at the University of Maryland School of Medicine, chose the Amish as subjects for their study due to their close genetic relationships, similar lifestyles, and low prescription drug usage, among...

Given the option to commit spiteful acts, reducing the money payoffs of others at no cost to themselves, many people avoid acting spitefully, but those that do, consistently impose the maximum harm, according to research reported on Aug. 15 in the open access journal PLoS ONE. The authors, Erik Kimbrough of Simon Fraser University in Canada and Philipp Reiss of Maastricht University in the Netherlands, created an artificial auction market scenario, with participants "bidding" for objects...

Coping with climate change presents a number of challenges, but we may be able to get some hints from our ancestors. A study of tools from an archaeological site outside Jerusalem provides new information about land use patterns at the times of extreme climate change that may have helped the population adapt to their changing environment. The full results are published Aug. 8 in the open access journal PLOS ONE. The authors of the study, led by Richard Yerkes of Ohio State University and...

A novel methodology shows that Wild meerkats engage in nine separate learning processes during foraging, and this method may provide general insight into learning mechanisms for groups of animals and culture development. The full report is published Aug. 8 in the open access journal PLOS ONE. The researchers, led by William Hoppitt of the University of St. Andrews in the United Kingdom, presented wild meerkats with a novel foraging TASK to investigate the animals' learning mechanisms. They...
