Jeff Blevins, associate professor and head of the University of Cincinnati's Department of Journalism, will present his research on Tuesday, April 9, at the 58th annual convention of the Broadcast Education Association in Las Vegas. Blevins' presentation, titled "Historical Amnesia in First Amendment Jurisprudence on Corporate Power and Electronic Media," suggests ...

Scientists have described small genetic changes that enable the H5N1 bird flu virus to replicate more easily in the noses of mammals. So far there have only been isolated cases of bird flu in humans, and no widespread transmission as the H5N1 virus can't replicate efficiently in the nose. The new study, using weakened viruses in the lab, supports the conclusions of controversial research published in 2012 which demonstrated that just a few genetic mutations could enable bird flu to spread between ferrets, which are used to model flu infection in humans. Researchers ...

London (08 April 2013). New research on patients' experiences of health services and how these relate to their expectations and satisfaction, published by the Journal of the Royal Society of Medicine, reveals that older people have higher expectations of their care and that they believe that their expectations are being met. The research questions prevailing stereotypes that characterise older patients as being satisfied with their care because their expectations are lower. Patients visiting their GP and hospital outpatient departments were surveyed before and after their ...

Mobile phone batteries that last longer, car batteries that enable you to drive further, storage that accumulates a lot of energy from wind and solar generators: many applications require better batteries. The research essentially focuses on three aspects here: researchers want to increase the energy density – in other words store more energy in a smaller battery. They are also looking to improve the discharging and charging speed by changing and controlling the material, shape and size of the electrochemically active particles and the structure of the battery electrodes ...

Philadelphia – Increasing the number of hours of sleep adolescents get each night may reduce the prevalence of adolescent obesity, according to a new study by researchers from the Perelman School of Medicine at the University of Pennsylvania. Results of the study show that fewer hours of sleep is associated with greater increases in adolescent body mass index (BMI) for participants between 14 and 18-years-old. The findings suggest that increasing sleep duration to 10 hours per day, especially for those in the upper half of the BMI distribution, could help to reduce the ...

Scientists from Cardiff University and the University of Barcelona have discovered new clues about past rapid climate change. The research, published this month in the journal Nature Geoscience, concludes that oceanographic reorganisations and biological processes are linked to the supply of airborne dust in the Southern Ocean and this connection played a key role in past rapid fluctuations of atmospheric carbon dioxide levels, an important component in the climate system. The scientists studied a marine sediment core from the Southern Ocean and reconstructed chemical ...

Alexandria, VA – For decades, scientists have used sophisticated instruments and computer models to predict the nature of droughts. With the threat of climate change looming large, the majority of these models have steadily predicted an increasingly frequent and severe global drought cycle. But a recent study from a team of researchers at Princeton University and the Australian National University suggests that one of these widely used tools — the Palmer Drought Severity Index (PDSI) — may be incorrect. The PDSI was developed in the 1960s as a way to convert multiyear ...

DURHAM, N.C. -- For more than 40 years, snowmelt and runoff from Morocco's High Atlas Mountains has been dammed and redirected hundreds of kilometers to the south to irrigate oases farms in the arid, sub-Saharan Draa Basin. But a new study by American and Moroccan scientists finds that far from alleviating water woes for the six farm oases in the basin, the inflow of imported water has exacerbated problems by dramatically increasing the natural saltiness of their groundwater. Researchers from Duke University in Durham, N.C., and Ibn Zohr University in Agadir, Morocco, ...

Researchers at Lund University in Sweden have discovered a new protein that controls the presence of the Vel blood group antigen on our red blood cells. The discovery makes it possible to use simple DNA testing to find blood donors for patients who lack the Vel antigen and need a blood transfusion. Because there has not previously been any simple way to find these rare donors, there is a global shortage of Vel-negative blood. The largest known accumulation of this type of blood donor is found in the Swedish county of Västerbotten, which exports Vel-negative blood all ...

Johns Hopkins scientists have found out how a gout-linked genetic mutation contributes to the disease: by causing a breakdown in a cellular pump that clears an acidic waste product from the bloodstream. By comparing this protein pump to a related protein involved in cystic fibrosis, the researchers also identified a compound that partially repairs the pump in laboratory tests. The mutation in question, known as Q141K, results from the simple exchange of one amino acid for another, but it prevents the protein ABCG2 from pumping uric acid waste out of the bloodstream and ...
