Strawjet: Invention of the Year, 2006

Invent Now 2006 Modern Marvel of the Year (links all broken by History Channel, so links were removed, – when will we finally have people in charge of websites that understand basic usability fundamentals?):

The Strawjet is a farm implement that processes straw (wheat, flax, sunflower, tobacco, hemp, etc.) in the field (after the plant has been harvested) into a mat, similar to a large bamboo window blind. This is used to construct composite building panels in much the same way as fiberglass or carbon fiber; however, the Strawjet uses a binder made from paper pulp, clay and cement rather than plastic resin.

Update, 2013: strawjet.com. Also I added this webcast from 2009

Read (except they broke all the links so you can’t) about more finalists in the History Channel and Invent Now Inventor contest:

  • Dr. David L. Cull, Hemoaccess Valve System
  • Kristin A. Hrabar, Illuminated Nutdriver
  • Dr. Sundaresan Jayaraman, Wearable Motherboard (Smart Shirt)
  • Robert C. Kelly, Resc-hue Lite Line

Drinking Soda and Obesity

Scientists in food fight over soda (bozos at CNN deleted the webpage):

Biologically, the calories from sugar-sweetened beverages are fundamentally different in the body than those from food.

The main sweetener in soda — high-fructose corn syrup — can increase fats in the blood called triglycerides, which raises the risk of heart problems, diabetes and other health woes.

This sweetener also doesn’t spur production of insulin to make the body “process” calories, nor does it spur leptin, a substance that tamps down appetite, as other carbohydrates do, explained Dr. George Bray of the Pennington Biomedical Research Center in Baton Rouge, Louisiana.

“There’s a lack of fullness or satiety. The brain just seems to add it on,” said Dr. Louis Aronne, a Weill-Cornell Medical College doctor who is president of the Obesity Society.

As with so much life science the “answers” are not clear (Medical Study Results Questioned – Why Most Published Research Findings Are False). The article presents arguments from those who disagree about the link between drinking soda and the dramatic rise in obesity in the USA.

Bannanas Going Going Gone

Can This Fruit Be Saved? by Dan Koeppel, Popular Science:

The banana as we know it is on a crash course toward extinction. For scientists, the battle to resuscitate the world’s favorite fruit has begun…

. It also turns out that the 100 billion Cavendish bananas consumed annually worldwide are perfect from a genetic standpoint, every single one a duplicate of every other. It doesn’t matter if it comes from Honduras or Thailand, Jamaica or the Canary Islands—each Cavendish is an identical twin to one first found in Southeast Asia, brought to a Caribbean botanic garden in the early part of the 20th century, and put into commercial production about 50 years ago.

That sameness is the banana’s paradox. After 15,000 years of human cultivation, the banana is too perfect, lacking the genetic diversity that is key to species health. What can ail one banana can ail all. A fungus or bacterial disease that infects one plantation could march around the globe and destroy millions of bunches, leaving supermarket shelves empty.

A wild scenario? Not when you consider that there’s already been one banana apocalypse. Until the early 1960s, American cereal bowls and ice cream dishes were filled with the Gros Michel, a banana that was larger and, by all accounts, tastier than the fruit we now eat.
