Projecting the charisma of a newly hired Chief Executive Officer often leads financial analysts to make crucial errors in forecasting the company's future performance, according to a new study in the current issue of Organization Science, a journal of the Institute for Operations Research and the Management Sciences (INFORMS®).

COLUMBIA, Mo. – As soon as babies are born, they are susceptible to diseases and infections, such as jaundice and e-coli. For up to a month, their immune systems aren't adequately developed to fight diseases. Although these infections are often minor, they can lead to serious problems if left untreated. To help strengthen newborns' immune systems, University of Missouri researchers have pinpointed a group of depleted white blood cells, which might lead to an immune-strengthening vaccine.
Although physicians support the use of electronic health records, concerns about potential privacy breaches remain an issue, according to two research articles published in the January 2010 issue of the Journal of the American Informatics Association (JAMIA), in its premiere issue as one of 30 specialty titles published by the BMJ (British Medical Journal) Group, UK.
An international team of Canadian and Spanish scientists have found the first potential immunological clue of why some people develop severe pneumonia when infected by the pandemic H1N1 virus.
DURHAM, N.C. – Scientists seeking to understand how to make an AIDS vaccine have found the cause of a major roadblock. It turns out that the immune system can indeed produce cells with the potential to manufacture powerful HIV-blocking antibodies – but at the same time, the immune system works equally hard to make sure these cells are eliminated before they have a chance to mature.
BOSTON (December 15, 2009) – Although seen as a potential heart disease therapy, raising high-density lipoprotein (HDL) cholesterol levels by inhibiting activity of a transfer protein may not be effective, a new study suggests. Scientists at the Jean Mayer USDA Human Nutrition Research Center on Aging (USDA HNRCA) at Tufts University and Boston University School of Medicine found an association between low plasma cholesterol ester transfer protein (CETP) activity and increased risk of heart disease in the Framingham Heart Study population.
Leipzig: Species distribution models are of only limited use in predicting the future distribution of mammals. This is the finding of a study of the climate niches of 140 indigenous European mammals. The researchers analysed data on species distribution, climate, land cover and topography, as well as the phylogenetic information of the species. Judging by the large differences in climate niches even for closely related species, mammals seem to adapt fast to changing climatic conditions. This in turn makes predictions based on current distributions unreliable.
Extinct woolly mammoths and ancient American horses may have been grazing the North American steppe for several thousand years longer than previously thought. After plucking ancient DNA from frozen soil in central Alaska, a team of researchers used cutting-edge techniques to uncover "genetic fossils" of both species locked in permafrost samples dated to between 7,600 and 10,500 calendar years.
In 2006, a team of Spanish and American researchers found the fossil remains of a whale, 4.5 million years old, in Bonares, Huelva. Now they have published, for the first time, the results of the decay and fossilisation process that started with the death of the young cetacean, possibly a baleen whale from the Mysticeti group.
COLLEGE PARK, Md. – Improving the energy efficiency of Maryland homes heated by natural gas would generate a "hat trick" of economic and environmental benefits over the next 10 years, including more than 80,000 new jobs, savings of hundreds of dollars in average heating bills and a nine percent reduction in residential carbon emissions, concludes a new study by the University of Maryland Center for Integrative Environmental Research (CIER).
Ghent, 15 December 2009 - Scientists at VIB and Ghent University in Flanders, Belgium have found an unexpected ally for the treatment of septic shock, the major cause of death in intensive care units. By inducing the release of nitric oxide (NO) gas in mice with septic shock, researchers Anje Cauwels and Peter Brouckaert discovered that the animal's organs showed much less damage, while their chances of survival increased significantly.
The analysis of microfossils found in ocean sediment cores is illuminating the environmental conditions that prevailed at high latitudes during a critical period of Earth history.
Around 55 million years ago at the beginning of the Eocene epoch, the Earth's poles are believed to have been free of ice. But by the early Oligocene around 25 million years later, ice sheets covered Antarctica and continental ice had developed on Greenland.
Westchester, Ill. – A study in the Dec. 15 issue of the Journal of Clinical Sleep Medicine shows that being overweight or obese increases the risk for developing obstructive sleep apnea (OSA) in adolescents but not in younger children.
Westchester, Ill. – A study in the Dec. 15 issue of the Journal of Clinical Sleep Medicine indicates that significant associations exist between parent-reported insomnia symptoms and medical complaints of gastrointestinal regurgitation and headaches in young school-aged children.
DALLAS – Dec. 15, 2009 – UT Southwestern Medical Center researchers have provided the most extensive account to date of the unique observable characteristics seen in patients with an extremely rare premature aging syndrome.
The findings, reported online and in the December issue of the Journal of Clinical Endocrinology and Metabolism, suggest that patients with atypical progeroid syndrome (APS) should not be lumped together with those diagnosed with two similar but more well-defined accelerated aging disorders called progeria and mandibuloacral dysplasia (MAD).
