Twitter can give power to the people

2013-04-18
(Press-News.org) Twitter can easily teach people about social movements such as Occupy Wall Street and even entice them to participate, according to a new study by a Michigan State University education researcher.

The social networking site – which lets users read, send and group together 140-character messages known as tweets – can actually be a better source of information than traditional news sources and online search engines, Benjamin Gleason reports in the journal American Behavioral Scientist.

"Reading on Twitter about a particular topic will expose learners to multiple perspectives – far more than is possible by reading a newspaper or even doing a Google search," said Gleason, a doctoral student in MSU's College of Education. "Imagine how much more rich and complex our teaching and learning could be if learners brought such diverse ideas into the classroom."

Gleason has been following Occupy Wall Street Twitter posts since the protest movement began in New York City's Wall Street financial district in September 2011. He compiled a database of tweets – documenting whether each tweet linked to a photograph, video or website – to figure out how users specifically learned from them.

Users can "tag" tweets for grouping with a preceding "#" symbol, or hashtag. Gleason said tweets tagged "#OWS," for #Occupy Wall Street, contained a wide range of information about the movement.

Gleason was part of a previous study (led by Christine Greenhow, MSU assistant professor of education) that found Twitter has become a new literary format that is improving student learning.

Gleason said the research offers "powerful implications for formal and informal educational settings – the most critical being that using Twitter can complement formal teaching and learning."

He added that he wants to see how students could use Twitter to learn about a complex topic of their own choosing.

"Basically, how young people read and write on Twitter may be similar to, and different from, reading and writing in other literacy spaces," Gleason said. "The question is: how can we support the literacy practices that young people are currently engaged in – how can we validate the learning that's already happening?"

Bursts of brain activity may protect against Alzheimer's disease

2013-04-18
Evidence indicates that the accumulation of amyloid-beta proteins, which form the plaques found in the brains of Alzheimer's patients, is critical for the development of Alzheimer's disease, which impacts 5.4 million Americans. And not just the quantity, but also the quality of amyloid-beta peptides is crucial for Alzheimer's initiation. The disease is triggered by an imbalance in two different amyloid species — in Alzheimer's patients, there is a reduction in a relative level of healthy amyloid-beta 40 compared to 42. Now Dr. Inna Slutsky of Tel Aviv University's Sackler ...

Best and worst times to start a fire

2013-04-18
In the Kimberley region of Western Australia, there are two distinct seasons: a wet season between December and March and a dry season between May and October. Reversals in the direction of prevailing winds are the driving force behind the seasonal shift. If there are going to be bush fires in the area's tropical savannas, the best time is early in the dry season, when vegetation has dried enough to burn but is still wet enough that fires won't grow out of control. In April and May, fires usually burn themselves out within a few days. The worst time for fire is late in ...

Distant blazar is a high-energy astrophysics puzzle

2013-04-18
Blazars are the brightest of active galactic nuclei, and many emit very high-energy gamma rays. New observations of the blazar known as PKS 1424+240 show that it is the most distant known source of very high-energy gamma rays, but its emission spectrum now appears highly unusual in light of the new data. A team led by physicists at the University of California, Santa Cruz, used data from the Hubble Space Telescope to set a lower limit for the blazar's redshift (z ≥ 0.6035), which corresponds to a distance of at least 7.4 billion light-years. Over such a great distance, ...

Experts examine Mediterranean diet's health effects for older adults

2013-04-18
According to a study published in the Journals of Gerontology Series A: Biological Sciences and Medical Sciences, a baseline adherence to a Mediterranean diet (MeDiet) is associated with a lower risk of hyperuricemia, defined as a serum uric acid (SUA) concentration higher than 7mg/dl in men and higher than 6mg/dl in women. Hyperuricemia has been associated with metabolic syndrome, hypertension, type 2 diabetes mellitus, chronic kidney disease, gout, and cardiovascular morbidity and mortality. The MeDiet is characterized by a high consumption of fruits, vegetables, legumes, ...

Anesthesia increases success rates of turning breech babies, reduces delivery costs

2013-04-18
STANFORD, Calif. — When a baby is in the breech position at the end of pregnancy, obstetricians can sometimes turn the baby head-down to enable a safer vaginal birth. In the past, women were not given anesthesia during the turning procedure, which requires the physician to push on the woman's abdomen while monitoring the baby with ultrasound. But a new study from the Stanford University School of Medicine and Lucile Packard Children's Hospital shows anesthesia is cost-effective because it increases the likelihood the procedure will work. The turning procedure, called ...

First steps of synapse building is captured in live zebra fish embryos

2013-04-18
EUGENE, Ore. -- (April 18, 2013) -- Using spinning disk microscopy on barely day-old zebra fish embryos, University of Oregon scientists have gained a new window on how synapse-building components move to worksites in the central nervous system. What researchers captured in these see-through embryos -- in what may be one of the first views of early glutamate-driven synapse formation in a living vertebrate -- were orderly movements of protein-carrying packets along axons to a specific site where a synapse would be formed. The discovery, in research funded by the National ...

Outpatients, hospital patients face growing, but different problems with antibiotic resistance

2013-04-18
CORVALLIS, Ore. – A new study concludes that problems with antibiotic resistance faced by outpatients may be as bad as those in hospitalized patients, and that more studies of outpatients are needed – both to protect their health and to avoid inappropriate or unnecessary drug use. Antibiotic resistance is a huge and growing problem in both hospital and outpatient settings. Failure to select an effective antibiotic, without appropriate consideration for this resistance, can increase the risk of continued illness or death. While 126 million prescriptions a year for antimicrobial ...

Identified as responsible for breast and ovarian hereditary cancer 3 mutations at BRCA1 gene

2013-04-18
Researchers of the hereditary cancer research group at the Bellvitge Biomedical Research Institute (IDIBELL) and the Catalan Institute of Oncology (ICO) conducted a functional and structural study of seven missense variants of the BRCA1 gene concluding that three of these variants are pathogenic, linked to the risk of suffering breast or ovarian cancer. The study has been published in the journal PLoS One The classification of these three variants will improve genetic counseling of patients and families who have these mutations and will serve to personalize the treatment. Mutations ...

Key ingredient in mass extinctions could boost food, biofuel production

2013-04-18
Hydrogen sulfide, the pungent stuff often referred to as sewer gas, is a deadly substance implicated in several mass extinctions, including one at the end of the Permian period 251 million years ago that wiped out more than three-quarters of all species on Earth. But in low doses, hydrogen sulfide could greatly enhance plant growth, leading to a sharp increase in global food supplies and plentiful stock for biofuel production, new University of Washington research shows. "We found some very interesting things, including that at the very lowest levels plant health ...

News focus on aggression in ice hockey shifted from violence to safety rules, equipment

2013-04-18
Popular media perspectives on traumatic brain injuries (TBI) in sports like ice hockey has changed over time and may influence people's attitudes towards these injuries, according to research published April 17 in the open access journal PLOS ONE by Michael Cusimano and colleagues from St. Michael's Hospital, Toronto, Canada. The authors compared articles published in the Chicago Tribune, New York Times, Toronto Star and Vancouver Sun from 1998-2000 and 2009-2011. They found the Canadian newspapers discussed aggression in ice hockey equally during both these time periods, ...
