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…)

Got Food Allergies? Thanks to UCLA, You Can Test Your Meal on the Spot Using a Cell Phone

Are you allergic to peanuts and worried there might be some in that cookie? Now you can find out using a rather unlikely source: your cell phone.

A team of researchers from the UCLA Henry Samueli School of Engineering and Applied Science has developed a lightweight device called the iTube, which attaches to a common cell phone to detect allergens in food samples. The iTube attachment uses the cell phone’s built-in camera, along with an accompanying smart-phone application that runs a test with the same high level of sensitivity a laboratory would. (more…)
