And no, I don’t just mean by recycling their coke cans! I still don’t like science much, but this story’s pretty cool:

Teen Finds Way to Decompose Plastic Bags in Just 3 Months!

by Kenny Luna, North Babylon, NY

If ordinary plastic bags would rot away like banana peels there’s no doubt a host of environmental problems would be solved, the fate of the turtle above included. And one 11th grader from Canada set out to make that dream come true as part of his school science project. A wildly successful endeavor he figures will make them decompose in just 3 months.

But how did this extraordinary young scientist named Daniel Burd pull it off?

Well, he decided the fact that they do, eventually, decompose after 1,000 years on their own meant there must be something out there causing it, and postulated that it might well be naturally occurring microorganisms behind it.

So he set about with the good old-fashioned scientific method as his guide, searching for the microorganisms, rarely found in nature, that actually do make plastic decompose.

Ultimately, he identified two strains of bacteria that work together to pull it off, with Sphingomonas serving as the primary decomposer with help from Pseudomonas.

And according to Burd, industrial application should be easy, “All you need is a fermenter . . . your growth medium, your microbes and your plastic bags.”

As many folks know, the simplest solutions are usually the ones that work best. And this kid has clearly come up with a potentially world changing idea.

girl suspended for highlights in her hair

One of the very first posts I ever wrote for this blog was about dress codes. At the time, in Dress codes at school and at work, I asked people’s opinions about dress codes and was fairly comfortable with my school’s policy. I wrote about it again when a student (and her family) sued her school about Tigger and Winnie the Pooh socks.

Now I am glad that my school isn’t as restrictive as Desert Wind School in Socorro, TX. There, an 8th grader is missing prom and graduation because of highlights in her hair. Not purple highlights. Not 5 foot long extensions. Just highlights. And I think she looks pretty cute!

This is from a TV station in El Paso:

Desert Wind School student Denise Guerrero, 14, knew it was against school policy to highlight her hair and she also knew the consequences: if she didn’t remove the highlights, she would miss out on her prom, class field trip, graduation ceremony and soccer games.

“Because I couldn’t be with my friends. I missed out on a lot of things,” said Guerrero.As KFOX reported, Guerrero was assigned to in-school suspension or SAC a month before the end of the school year because she has blond highlights in her hair. She was also told she couldn’t participate in any school activities.Her parents filed a grievance with the Socorro Independent School District. They disagree with the school’s policy and they state other students and teachers color or highlight their hair at Desert Wind School.

But her family disagrees:

“According to their policy, highlights are a distraction. Why isn’t it a distraction by teachers, only by the students,” said Rafael Magallanes, Guerrero’s stepfather.

The principal responded to the grievance and echoed what district officials had told KFOX before. They say the dress code only applies to students and it is applied equally, fairly and thoroughly for all students.Just one week before the end of year activities at Desert Wind, Guerrero discovered the school would not amend the policy. She was told her hair had to go back to her natural color if she wanted to participate in school events. Guerrero said she stood her ground because she felt the policy is not fair. She knew she would be sacrificing events and memories she will never relive.”Soccer, my favorite sport, which I couldn’t get in because of a policy which couldn’t be changed, that’s what hurt me the most,” said Guerrero.Guerrero’s parents could have continued with the grievance process but this year was Denise’s last.

But the point is, what’s too much restriction for a public school? Banning profanity is one thing. Banning blond is just stupid.  It could be worse.  She could have hair like THIS:
