Shark migrations studied with underwater robot along Delmarva Peninsula

University of Delaware researchers are using an underwater robot to find and follow sand tiger sharks that they previously tagged with transmitters. The innovative project is part of a multi-year partnership with Delaware State University to better understand the behavior and migration patterns of the sharks in real time.

“In the past week our new, specially equipped glider OTIS – which stands for Oceanographic Telemetry Identification Sensor – detected multiple sand tiger sharks off the coast of Maryland that were tagged over the past several years,” said Matthew Oliver, assistant professor of oceanography in UD’s College of Earth, Ocean, and Environment. “This is the first time that a glider has found tagged sharks and reported their location in real time.” (more…)

Nearly 2 in 5 Tablet Owners Read Newspapers and Magazines on Their Device in August

Kindle Fire Owners Most Likely to Consume News According to comScore TabLens

RESTON, VA, October 17, 2012 – comScore, Inc., a leader in measuring the digital world, today released a study of tablet newspaper and magazine readership based on data from its comScore TabLens service. The study found that nearly 2 in 5 U.S. tablet owners read newspapers and/or magazines on their device in August, with 1 in 10 reading publications almost daily. Analysis of readership activities across platforms revealed that Kindle Fire users displayed the strongest propensity for reading newspapers and magazines on their device.

“Tablets are fundamentally redefining how people consume news and information, with the format more conducive to reading longer form content than PCs or smartphones,” said Mark Donovan, comScore SVP of Mobile. “In the case of online newspapers, tablets are now driving 7 percent of total page views, an impressive figure considering the relative infancy of the tablet space. Publishers that understand how these devices are shifting consumption dynamics will be best positioned to leverage this platform to not only drive incremental engagement among current subscribers but also attract new readers.” (more…)

New Insights into How Genetic Differences among Individuals Influence Breast Cancer Risk from Low-Dose Radiation

Berkeley Lab research could lead to new ways to ID women who have higher risk of breast cancer from low-dose radiation

Scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have identified tissue mechanisms that may influence a woman’s susceptibility or resistance to breast cancer after exposure to low-dose ionizing radiation, such as the levels used in full-body CT scans and radiotherapy.

The research could lead to new ways to identify women who have higher or lower risks of breast cancer from low-dose radiation. Such a predictive tool could help guide the treatment of cancer patients who may be better served by non-radiation therapies. (more…)

IBM and Oxford Survey: Getting Closer to Customers Tops Big Data Agenda

Less than half of organizations analyzing external data; only 43 percent looking at social media for deeper understanding about consumer preferences
Lack of advanced analytics skills for tackling unstructured data biggest challenge

ARMONK, N.Y. and OXFORD – 17 Oct 2012: A new global report released today by IBM and the Saïd Business School at the University of Oxford reveals that most Big Data initiatives currently being deployed by organizations are aimed at improving the customer experience. Yet, despite the strong focus on the customer, less than half of the organizations engaged in active Big Data initiatives are currently collecting and analyzing external sources of data, like social media.

One reason is that many organizations are struggling to address and manage the uncertainty inherent within certain types of data, such as the weather, the economy, or the sentiment and truthfulness of people expressed on social networks. In the survey, respondents questioned their ability to trust comments, reviews, tweets and other forms of freely offered opinions online. While uncertain, social media data still contains valuable information. Organizations need to embrace and manage data uncertainty and determine how to use it to their advantage. (more…)

Exercise May Lead to Better School Performance for Kids with ADHD

EAST LANSING, Mich. — A few minutes of exercise can help children with attention deficit hyperactivity disorder perform better academically, according to a new study led by a Michigan State University researcher.

The study, published in the current issue of the Journal of Pediatrics, shows for the first time that kids with ADHD can better drown out distractions and focus on a task after a single bout of exercise. Scientists say such “inhibitory control” is the main challenge faced by people with the disorder. (more…)

Purpose and Uses of the Relay Board for Electronics Hobbyists and Enthusiasts

A relayboard is effectively a board containing one or more relay switches. A relay switch is often used to switch a large amount of power on for a small operating energy; or to turn specific circuits on and off within an application.

Often the relay becomes the breaker point between a low and high voltage, or a low and high current, part of an application. The most obvious version of this usage is the RCD board used to insulate your home against electrical surges. The trip switches on the board are all relays – in effect making the RCD (otherwise known as a residual current device) one of the largest and most obvious relay boards in the country. (more…)

Graphene Membranes May Lead To Enhanced Natural Gas Production, Less CO2 Pollution, Says CU Study

Engineering faculty and students at the University of Colorado Boulder have produced the first experimental results showing that atomically thin graphene membranes with tiny pores can effectively and efficiently separate gas molecules through size-selective sieving.

The findings are a significant step toward the realization of more energy-efficient membranes for natural gas production and for reducing carbon dioxide emissions from power plant exhaust pipes.

Mechanical engineering professors Scott Bunch and John Pellegrino co-authored a paper in Nature Nanotechnology with graduate students Steven Koenig and Luda Wang detailing the experiments. The paper was published Oct. 7 in the journal’s online edition. (more…)

A joint effort of citizen scientists and professional astronomers has led to the first reported case of a planet orbiting twin suns that in turn is orbited by a second distant pair of stars.

Aided by volunteers using the Planethunters.org website, a Yale-led international team of astronomers identified and confirmed discovery of the phenomenon, called a circumbinary planet in a four-star system.

Only six planets are known to orbit two stars, according to researchers, and none of these are orbited by distant stellar companions. (more…)
