Reappraisal Defuses Strong Emotional Responses to Israel-Palestine Conflict

Reappraisal is a widely-used cognitive strategy that can help people to regulate their reactions to emotionally charged events. Now, new research suggests that reappraisal may even be effective in changing people’s emotional responses in the context of one of the most intractable conflicts worldwide: the Israeli-Palestinian conflict.

“Negative intergroup emotions play a crucial role in decisions that perpetuate intractable conflicts,” observes lead researcher Eran Halperin of the New School of Psychology at the Interdisciplinary Center in Israel. (more…)

Business Promotional Products Explained – What They Are and How They Are Used

Business promotional products are any items that may be used to promote something about a business. That might be the whole brand – or it might be a specific product or message from within that brand.

Promotional items may be anything at all, as long as they are either directly branded or used in a way that has immediate relevance to a promotion or campaign. Such a promotion or campaign can be targeted for immediate return (as in a product launch) – or it can be a long term promotion, like getting workers within a company to wear branded protective clothing when they do a job.

Flexing Fingers for Micro-Robotics: Berkeley Lab Scientists Create a Powerful, Microscale Actuator

Berkeley, Calif., Dec. 2012 — Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California, Berkeley, have developed an elegant and powerful new microscale actuator that can flex like a tiny beckoning finger. Based on an oxide material that expands and contracts dramatically in response to a small temperature variation, the actuators are smaller than the width of a human hair and are promising for microfluidics, drug delivery, and artificial muscles.

“We believe our microactuator is more efficient and powerful than any current microscale actuation technology, including human muscle cells,” says Berkeley Lab and UC Berkeley scientist Junqiao Wu. “What’s more, it uses this very interesting material—vanadium dioxide—and tells us more about the fundamental materials science of phase transitions.” (more…)

Environmental Cost of Agriculture: Soil Determines Fate of Phosphorous

Brazil’s soybean yields have become competitive with those of the United States and Argentina, but the soil demands a lot of phosphorous, which is not renewable. In the United States, meanwhile, historical applications of the fertilizer have polluted waterways. What accounts for these problems? It’s the soils, according to a new study comparing agriculture in the three countries.

PROVIDENCE, R.I. [Brown University] — Just 20 years ago, the soils of the Amazon basin were thought unsuitable for large-scale agriculture, but then industrial agriculture — and the ability to fertilize on a massive scale — came to the Amazon. What were once the poorest soils in the world now produce crops at a rate that rivals that of global breadbaskets. Soils no longer seem to be the driver — or the limiter — of agricultural productivity. But a new Brown University-led study of three soybean growing regions, including Brazil, finds that soils have taken on a new role: mediating the environmental consequences of modern farming.

Slinky Science Inspires African School Children

A University of Exeter physicist has inspired hundreds of African school children to engage with science during a whirlwind outreach tour to Malawi.

Professor Pete Vukusic used simple interactive demonstrations including slinky springs, glass prisms, light sticks and iridescent butterflies to enthral large classes of pupils and teachers in underprivileged rural schools.

The charismatic lecturer combined use of the demos and an interactive and engaging teaching style to explain fundamental and modern science principles to students who are used to formal instructional teaching methods. Professor Vukusic hopes his visit will both help to inspire science learning in these schools and help their teachers adapt to more modern techniques that engage young people more effectively.

The Teacher’s Apple

A decade ago, electronics and cell phones in the classroom were considered little more than a distraction. Today, new devices such as tablet computers and smartphones are changing this perception. Educators are finding innovative ways to supplement their lectures with the newest technology, and students are beginning to see their devices as essential components of their college experience.

Naturally, major device manufacturers are now battling for dominance in the field. Below, we explore how Apple is winning the battle for education technology and what gives them the edge over the sizable competition in the market. (more…)
