Just like everything nowadays, fireworks are bad for you.

Explosions, strange chemical combinations, danger, all that sort of thing.

So what can we do about it, while retaining some semblance of Fourth of July fun?

This article tells all.

At the end, of course, it admits that fireworks are not that bad a pollution problem compared to all the others we already have ... but every little bit helps.

The research began by asking whether certain promiscuous gay men were able to have sex with AIDS carriers without getting the disease themselves.

The AIDS virus, like other disease carriers, needs a foothold in the body in order to invade cell and do its destructive work. A certain gene pattern, carried by the aforementioned gay men, made this foothold possible.

By removing that gene pattern, scientists were able to run successful experiments on mice. When they were injected with HIV they did not get the disease.

Even people who already have AIDS may be helped. By injecting cells with the new gene pattern into the body, they may be able to overwhelm the existing AIDS-carrying cells and reduce the impacts of the disease.

Further research will, of course, be necessary but this is a very promising field of inquiry.

Top Gear magazine of the UK pitted a BMW M3 against a Toyota Prius for fuel economy.

An easy win for the Toyota, right?

Turns not, no, not if the Toyota is driven as fast as possible. If you're trying to get the most performance out of your car, it's better to drive the performance car.

In their test, the Toyota got 17.2 miles per gallon and the BMW 19.4.

So if you want to drive fast, don't buy an economy car. You'll get just as bad economy and have less fun.

The hilarious video is at the link.

Earlier, we mentioned technology that used microbes to convert biological junk like wood chips into an oil-like substance that was both non-polluting and usable in today's gas tanks.

Today we talk about invasive species like Kudzu, that grow like crazy and choke up native plants, and how they can be used as fuels.

Put this all together and tomorrow's fuels of the future look pretty exciting.

Now if we can just get through the present ...

Well, if you have a big enough back yard, that is. Two electric motors propel the beast, and you can roll around your yard, creating the same vertiginous effects as a coaster.

The project is in development, and there's video at the link.

One of the amazing things about Pixar is that they deliberately seem to seek a challenge. Who would want to see a film, however brilliant, about a fish looking for his son? A rat chef? Or, in their latest venture, a trash-collecting robot who can't even talk?

Well, I did, and the odds are you will too.

There are too many reviews of Wall*e out for me to detail the plot, but I'll mention a few things I think others have missed.

First, one of the few flaws of the plot is that I think I liked the dystopian world of the shiny BuyNLarge ship better than the dystopian, trash-strewn, worn out earth. Why would you want to leave the glittering ship for that?

Second, Andrew Stanton said the film wasn't meant to be political, even though it was about BuyNLarge Corporation taking over the world. I think his critique of our society is much more about lifestyle choices like getting fat and becoming a sedentary nation of TV watchers and computer users. The sequences where people on the ship were made to ignore the telescreen and see each other were great. "Hey, I didn't even realize this ship had a pool!" was a great line.

BuyNLarge is an obvioius Wal*Mart parody although I wonder if we would ever trust Wal*Mart to take over space exploration and public transport.

It's amusing that even though we have a dystopian future where things don't quite work out as planned, once we are in the ship all the technology works flawlessly.

No question, Pixar has created a brilliant, hilarious hit with heart, again. Go see it!

We covered this about a week ago, but this article has more detail on how environmentally friendly biofuels from genetically engineered bacteria will work.

"By swapping natural genes in yeast and bacteria for synthetic ones, scientists have tricked the microbes into producing hydrocarbons—creating, in essence, billions of tiny refineries to turn simple sugars into environmentally friendly diesel, gasoline, jet fuel and biocrude."

This looks like an exciting breakthrough - fuel that works just like gas or diesel in a car, but is non-polluting and based on renewable resources.

We do live in interesting times and sometimes, unlike the Chinese proverb, that's GOOD news.

Traditionally, a nightclub is a giant energy sucking machine, with its powerful sound system and thousands of watts worth of flickering lights.

Club4Climate decided to change this - up to 60% of the energy used by the club comes from spring-filled floors set up to generate power!

It's a cool idea but looks a little hypocritical - that remaining 40%, after all, comes from good old fashioned generators.

I still admire the idea, but the promoters could be a shade less sanctimonious about it. Perhaps that's why Friends of Earth refused a donation -- they claim the Club encourages international flights.

License agreements, those annoying blocks of text that go on forever, and that you have to agree to in order to use the software you've purchased or downloaded, are a staple of modern life.

So how many people read them? One developer decided to find out, by offering "consideration" to anyone who read the agreement. After 3,000 downloads of the software, someone finally emailed the special address in the agreement.

He was promptly mailed a check for $1,000.

I assume the offer is now closed :-(.
