Maize as Food

Corn is prepared and consumed in a multitude of ways. Ground and pounded, the meal may be boiled, baked or fried, cooked with water to provide a thick mush or dough, or a thinner consistency to provide gruel, porridge or soup. The whole grain may be boiled or roasted and it may be fermented. Tamales are produced by steaming the dough. Cornbread is made by mixing the meal with wheat flour. Immature cobs, preferably sweet corn, are boiled and eaten as corn on the cob, or the grain may be removed and eaten as a vegetable, or it may be canned. More mature cobs are roasted.

Last week we talked about how corn or maize came to be one of the most important cereals in the world. This week, a look at the maize as food.

Maize

Some facts about corn:

  • An ear of corn averages 800 kernels in 16 rows.
  • A pound of corn consists of approximately 1,300 kernels.
  • 100 bushels of corn produces approximately 7,280,000 kernels.
This week, a look at what we call corn and what much of the world calls maize.

What are you looking at? Scientists find out

We see with the brain, not the eyes; images that pass through our pupils go no further than the retina. From there image information travels to the rest of the brain by means of coded pulse trains, and the brain, being highly plastic, can learn to interpret them in visual terms.

Ever wonder that your brain sees? We may know sooner that later, as Japanese researchers have reproduced images of things people were looking at by analyzing brain scans.

This week a look at how the brain, well, looks at things.

Building a Better Bee

Bees, like ants, are a specialized form of wasp. The ancestors of bees were wasps in the family Crabronidae, and therefore predators of other insects. The switch from insect prey to pollen may have resulted from the consumption of prey insects that were flower visitors and were partially covered with pollen when they were fed to the wasp larvae.

Bees are adapted for feeding on nectar and pollen, the former primarily as an energy source, and the latter primarily for protein and other nutrients. Most pollen is used as food for larvae. Bees play an important role in pollinating flowering plants, and are the major type of pollinator in ecosystems that contain flowering plants.

In early 2007, abnormally high die-offs (30-70% of hives) of European honey bee colonies occurred in the US and possibly Québec; such a decline seems unprecedented in recent history. This has been dubbed "Colony Collapse Disorder" (CCD).

This week, we look at research from UC Davis (go Aggies!) on building a better bee that may be resistant to CCD.
