Study Highlights How Twitter is Used to Share Information After a Disaster

A study from North Carolina State University shows how people used Twitter following the 2011 nuclear disaster in Japan, highlighting challenges for using the social media tool to share information. The study also indicates that social media haven’t changed what we communicate so much as how quickly we can disseminate it.

“I wanted to see if Twitter was an effective tool for sharing meaningful information about nuclear risk in the wake of the disaster at the Fukushima Daiichi nuclear plant,” says Dr. Andrew Binder, an assistant professor of communication at NC State and author of a paper describing the work. “I knew people would be sharing information, but I wanted to see whether it was anecdotal or substantive, and whether users were providing analysis and placing information in context.

ANN ARBOR, Mich.— Popular firewall technology designed to boost security on cellular networks can backfire, unwittingly revealing data that could help a hacker break into Facebook and Twitter accounts, a new study from the University of Michigan shows.

The researchers also developed an Android app that tells phone users when they’re on a vulnerable network. They will present their work May 22 at the IEEE Symposium on Security and Privacy in San Francisco. (more…)

Majority of Egyptians Faults Brotherhood Fielding its Own Candidate

COLLEGE PARK, Md. – As Egypt prepares this week to elect its first president since the 2011 revolution, a new University of Maryland poll finds the Muslim Brotherhood’s candidate tied for fourth place. Researchers describe the race as fluid.

The poll confirms the strategic damage inflicted by the Brotherhood’s decision to field its own candidate, after saying it would not. Nearly three-quarters of those surveyed (71 percent) called the decision a “mistake.”

The poll also shows Egyptians approaching the race differently from Parliamentary elections, focusing more on personal trust and the economy over party affiliation. (more…)

New Study by WHOI Scientists Provides Baseline Measurements of Carbon in Arctic Ocean

Scientists from the Woods Hole Oceanographic Institution (WHOI) have conducted a new study to measure levels of carbon at various depths in the Arctic Ocean. The study, recently published in the journal Biogeosciences, provides data that will help researchers better understand the Arctic Ocean’s carbon cycle—the pathway through which carbon enters and is used by the marine ecosystem. It will also offer an important point of reference for determining how those levels of carbon change over time, and how the ecosystem responds to rising global temperatures.

“Carbon is the currency of life. Where carbon is coming from, which organisms are using it, how they’re giving off carbon themselves—these things say a lot about how an ocean ecosystem works,” says David Griffith, the lead author on the study. “If warming temperatures perturb the Arctic Ocean, the way that carbon cycles through that system may change.” (more…)

What Does Islam Say About the Fate of Non-Muslims?

EAST LANSING, Mich. — Since Sept. 11, it has become increasingly common to hear about Muslims who condemn all non-Muslims – or “infidels” – to hell, but this has never been a foundation of Islamic thought, argues a Michigan State University professor who recently published a first-of-its-kind book on non-Muslim salvation.

New Silicon Memory Chip Developed

The first purely silicon oxide-based ‘Resistive RAM’ memory chip that can operate in ambient conditions– opening up the possibility of new super-fast memory – has been developed by researchers at UCL.

Resistive RAM (or ‘ReRAM’) memory chips are based on materials, most often oxides of metals, whose electrical resistance changes when a voltage is applied – and they “remember” this change even when the power is turned off.

ReRAM chips promise significantly greater memory storage than current technology, such as the Flash memory used on USB sticks, and require much less energy and space. (more…)

Yahoo! Board Increases Share Repurchase Plan by US$5 Billion

SUNNYVALE, Calif. & HANGZHOU, China — Yahoo! Inc. and Alibaba Group Holding Limited today announced they have entered into a definitive agreement for a staged and comprehensive value realization plan for Yahoo!’s stake in Alibaba.

The first step is the repurchase by Alibaba of up to one-half of Yahoo!’s stake, or approximately 20% of Alibaba’s fully-diluted shares. The purchase price will be based on a valuation of Alibaba to be established through equity financings that Alibaba intends to undertake to finance the transaction, subject to a floor valuation of approximately US$35 billion. The agreement includes substantial financial incentives for Alibaba to raise the additional equity at a valuation higher than US$35 billion. At the minimum price and assuming the initial repurchase of the full 20% stake, Yahoo! would receive from Alibaba consideration of approximately US$7.1 billion, composed of at least US$6.3 billion in cash proceeds and up to US$800 million in newly-issued Alibaba preferred stock.
