Very interesting book by Calestous Juma, buy it or download for free. Highly recommended for students interested in the future of Africa and food security.
"African agriculture is currently at a crossroads, at which persistent food shortages are compounded by threats from climate change. But, as this book argues, Africa faces three major opportunities that can transform its agriculture into a force for economic growth: advances in science and technology; the creation of regional markets; and the emergence of a new crop of entrepreneurial leaders dedicated to the continent's economic improvement."
Follow this for the latest news about food production and demand around the world. Who needs to make up interdisciplinary problems when we have real ones for our students to grapple with?
“How much water does it take to produce 1 kg of rice?" It's a good question. Did you know that "around onequarter to one-third of the world’s developed freshwater resources are used to irrigate rice (which, it must be remembered, is the staple food for almost half the world’s population)". Follow the link to see how they came up with that figure.
Have you seen John and Hank Green's Crash Course videos? They're cute, entertaining and accessible introductions to various topics in biology (Hank) and History (John).
This one covers Biological Molecules, which are also covered in our next Teaching Tool, "Plants, food and human health: You are what you eat?" (which should be out soon!).
Very thorough summary of best practices for growing Arabidopsis. What size pots? What temperature? How much light? With photos and references. Good resource for student researchers!
Don't forget to share this one with them too:
The top 10 ways to kill Arabidopsis, by Sean May at NASC.
Tips and trouble shooting for quantitative and qualitative immunoblotting. Sample harvesting, Protein extraction, Detection, Quantitative western blot etc ...
Do you like blood oranges? Do you know why they are red, and why the redness of a single variety varies from year to year? Nice story here, and nice video!
If you or your students like to take photos of plants [or plant cells, or plant research(ers)], consider adding them to the flickr Fascination of Plants Day group. Flickr is a free, easy-to-use social repository for photos. You can retain full rights, or you can post them under a creative commons license so that others can use for non-profit purposes....
This is a very nice short essay on what it means to be a teacher. Added bonus for those of us who are linguistically challenged: the origins of the words "pedagogy" and "education" (Greek and Latin origins, but meaning what?).
"Documenting phenological patterns can be a straightforward and cost-effective strategy for engaging students in the science of observation with little need for additional equipment or supplies."
and
"Finally, we advocate for including creativity in the reward structure of college-level biology........ If we truly want to cultivate a nation of problem-solvers, we must allow students opportunities to wrestle with real problems and be rewarded for conceiving creative strategies for solving them. Our students have shown us they are ready for the challenge."
How do you feel about tweeting in the classroom? If your answer is either "?" or "I hate it", you might want to read this very good article. John Hawks, Professor of Anthropology at University of Wisconsin, shares some compelling ideas on how Twitter can enhance the student learning experience, as well as a primer on how to tweet, twetiquette, and links to stories by other fans of classroom tweeting.
Share this with your students when they're getting ready to practice writing like a scientist - it might not help them write better, but it'll help them realize that they're not alone in finding it a challenge!
On Sunday, Cornell University’s corpse flower (Amorphophallus titanum), a gigantic Sumatran plant that reeks of death, bloomed. It was one of only 140 such plants to bloom in cultivation in recorded history.
If you missed this Plant Cell 2011 review about calcium-regulated gene expression, here's your second chance. It's open access, and very well-written. Have a look if you're interested in calcium as a second messenger, or, if you're not, have a look and maybe you'll change your mind!
This interesting article from the African Technology Development Forum (ATDF) discusses the meaning of "food sovereignty" versus "food security".
Proponents of food sovereignty say, "Food sovereignty is the right of each nation to maintain and develop its own capacity to produce its basic foods respecting cultural and productive diversity. Food sovereignty is a precondition to genuine food security"
But is it? How does international trade affect farmers in developing economies? When you buy your green beans imported from Kenya, what effect are you having?
To ask the question another way, is North Korea food-secure? Why or why not?
This paper raises some very interesting questions and is sure to lead to stimulating class discussions.
We are big fans of the BIO fortified blog (and their GENERA database). You've probably seen the term "Agent Orange Corn" kicked around - what's that all about? Steve Savage explains, and explains again in the comments section. Good reading, and fascinating issues, both scientific and social.
Opening line:
Mark Twain once said, “A lie can travel half way around the world while the truth is putting on its shoes.”
Two articles, from Nature Jobs and the Chronical for Higher Education, on what lies ahead for today's students. How are higher education institutions addressing the twin concerns of short-term contracts and unreasonable time expectations? What are the long-term prospects for students just starting their careers?
Tomorrow is Darwin's birthday (12 Feb), and we are only three months away from Fascination of Plants Day (18 May).What great opportunities to share your passion for DNA, genetics, plants and careers in science! If you are not already participating, check out the FoPD website to hook up with an organization that is, or start your own event (http://www.plantday12.eu/).
Here are some resources to help you talk about DNA and plants.
Check out Peggy Lemaux's and Barbara Alonso's "DNA for Dinner" materials. There are a LOT of very clever ideas here including hands-on games for groups as well as simple solo activities. For example, you could print out and laminate this PDF file (http://ucbiotech.org/dnafordinner/lesson2/handout_2.5/index.html), cut out the sequences and let people figure out how to assemble a genome by matching overlapping sequences. We really like the fruit and vegi family poster shown above, available here (http://ucbiotech.org/dnafordinner/lesson1/handout_1.2/index.html), which you could hang behind a table full of real fruits and vegetables so that people can take a close look at the plants they eat. The site also has suggestions for plant family activities.
If you need some motivation to participate in public outreach, here are a few thoughts about what works (start from 6 minutes in if you want just the outreach spiel) (http://ed.ted.com/on/XBSQKCCl). Giving anyone a flower to dissect and draw really works!
If you are talking to older students about career paths, here's a post talking about the hot job market in statistical genetics, a good albeit challenging career path
Strigolactones are hormones that are involved in shoot branching, and their secretion into the soil both stimulates colonization by mycorrhizal fungi, and germination of Striga and other parasitic plants. This new Nature paper (subscription required) shows how the strigolactone hormones are transported out of the plant cells, with far-ranging implications.
The 2009 video "Naturally obsessed; the making of a scientist" is available here to watch for free. If you're talking with your students about careers in science, share this with them. There is more to being a scientist than just career prospects, right?
