Dispersants used on BP Spill contain chemicals associated with cancer: new report

bp-chemical-dispersant

What a non-surprise.

Many of us sounded the alarm as soon as we learned of BP’s plans to dump huge quantities of the chemical dispersant Corexit into the Gulf in an attempt to break up the oil slick. Experts were concerned, seeing as how the chemical had never been used in such quantities before, nor in such a manner — until the federal government made them stop, BP was blasting the stuff directly into the source, seeking to disperse the oil before it even reached the surface.

Well, now Earth Justice has completed a report on the chemicals that were used in the different blends of dispersant, and it appears that at least some of those fears were well-founded…

Dolphins now conch fishing

dolphingeniousfis

Dolphins are very smart creatures.

Researchers from Murdoch University have been watching bottlenose dolphins in Shark Bay, Australia develop an ingenious way to fish. First witnessed by researchers in 2007, a dolphin will use a conch shell to trap and scoop up fish. The dolphin will then proceed to pour the fishies into its mouth as if they were the bottoms of a chip bag. The remarkable part is that this behavior seems to be becoming more widespread, marking it as a trend learned…

Brazil builds $127 billion “Offshore City” to harvest oil in the deep sea

brazil-offshore-oil-city

Brazil is set to start gathering oil in new places.

Want to get a feel for how crazy the post-peak oil fossil fuels industry is getting? Here’s as good an example as any: Brazil’s state-owned oil company Petrobras is about to embark on an unprecedented oil-gathering mission. It’s about to attempt to extract 30 billion barrels of oil from reserves that are locked in deepwater sub-salt fields at least 60 miles off the coast and up to five miles underwater. In order to get at the incredibly hard-to-get oily good stuff, Brazil is spending an estimated $226 billion — and $127 billion will be spent on exploration and production alone.

The product of that venture is already taking shape: a veritable floating “offshore city” has sprung up over 100 kilometers (62 miles) off the coast of Brazil, and it will lead the effort to drill into the deep sea sub-salt…

Researchers identify food price tipping point linked to rioting

Rising food costs are a key reason behind rioting.

There’s no doubt that rising food prices in a specific area can lead to rioting. We have plenty of current and historic examples of that. But some interesting new research highlighted in Technology Review shows that once average global food prices cross a certain threshold a tipping point is reached after which “almost anything can trigger a riot, like a lighted match in a dry forest.”

Check out this graph which plots the UN Food Price Index against the dates of riots around the world…

How fake money saved Brazil

real

Brazil has faced hyperinflation in the past.

Twenty years ago, Brazil found itself in the grips of hyperinflation. Its inflation rate hit 80% a month, and the country was in financial free fall.

Economists at the Catholic University in Rio came up with an unlikely – but ultimately successful – plan to rescue the country. And would you believe it, the plan calls for fake money..

90 percent of US net users don’t know about ‘crtl-F’

FFFFFFFFFFFFFFFFf

Did you know about using Control-F?

Dan Russell, one of Google’s anthropologists, conducted a largeish survey of user behavior and discovered that 90 percent of American Internet users don’t know that crtl-F will let them search documents including Web pages. I recently discovered that a smart and technologically literate friend had never heard of alt-tab for application switching; alt-tab being my single most used key combo!

It strikes me that we could probable come up with a list of ten (or even three) things you could teach to the people around you the next time you sit down to help them with a technology problem, “three things every technology user should know.”
