However unlike the Green Revolution 30 years ago, there is virtually no more tillable-land available to grow rice. Future gains must be made solely by improving rice yields, and on top of that, there's an imperative to use fewer harmful chemicals as fertilisers and for pest control.

The Smithsonian geared the 60 videos towards junior high schoolers and above, and they are usually a minute in length. The videos answer those questions kids, and sometimes adults wonder like " Does Stress Turn Your Hair Gray?" or "Why Do Songs Get Stuck in My Head?"
Idén kom i ren desperation. Att lösa världens klimatproblem genom att spruta ut svavelpartiklar högt upp i atmosfären - det ska man göra i absolut sista ögonblicket.

Textuality is often thought of in linguistic terms; for instance, the talk and writing that circulate in the classroom. In this paper I take a multimodal perspective on textuality and context. I draw on illustrative examples from school Science and English to examine how image, colour, gesture, gaze, posture and movement—as well as writing and speech—are mobilized and orchestrated by teachers and students, and how this shapes learning contexts. Throughout the paper I discuss the issues raised by a multimodal perspective for the conceptualization of text and learning context, and how this approach can contribute to learning and pedagogy more generally. I suggest that attending to the full ensemble of communicative modes involved in learning contexts enables a richer view of the complex ways in which curriculum knowledge (and policy) is mediated and articulated through classroom practices.
