Stealth sharks to patrol the high seas

More controversially, the Pentagon hopes to exploit sharks’ natural ability to glide quietly through the water, sense delicate electrical gradients and follow chemical trails. By remotely guiding the sharks’ movements, they hope to transform the animals into stealth spies, perhaps capable of following vessels without being spotted. The project, funded by the Defense Advanced Research Projects Agency (DARPA), based in Arlington, Virginia, was presented at the Ocean Sciences Meeting in Honolulu, Hawaii, last week

Read the Tom’s Dispatch article for a bigger picture look, excellent paragraph here, one can’t help but wonder…

To support letting inventive minds roam free outside normal frameworks is in itself an inspired idea. But I bet there’s no DARPA-like agency elsewhere in the government funding the equivalent for education 2025 or health 2025 or even energy independence 2025. To have this happen, I’m afraid, you would have to transform them into Northcom war games.

I do not believe that throwing money into research solves all problems, but I wonder what would happen if the US of A did not spend all its spare cash and (up to the eyeballs) in debt on defense. The incredible amounts of money spent on defense makes many people rich, keeps many companies afloat, creates many jobs, etc. But so would massive amounts of government funding on pretty much any other, more worthwhile venture.

Benzene Levels in Soft Drinks Above Limit – Yahoo! News

WASHINGTON – Cancer-causing benzene has been found in soft drinks at levels above the limit considered safe for drinking water, the Food and Drug Administration acknowledged Wednesday.
Even so, the FDA still believes there are no safety concerns about benzene in soft drinks, or sodas, said Laura Tarantino, the agency’s director of food additive safety.”We haven’t changed our view that right now, there is not a safety concern, not a public health concern,” she said. “But what we need to do is understand how benzene forms and to ensure the industry is doing everything to avoid those circumstances.”

The admission contradicted statements last week, when officials said FDA found insignificant levels of benzene.

In fact, a different study found benzene at four times the tap water limit, on average, in 19 of 24 samples of diet soda.

The formation of benzene in soft drinks is from the reaction of ascorbic acid (aka Vitamin C) and benzoate salts, notably sodium benzoate which is used as a preservative. As the FDA letter states:

We learned that elevated temperature and light can stimulate benzene formation in the presence of benzoate salts and vitamin C, while sugar and EDTA salts inhibit benzene formation.

Is this a pressing concern? First of all, exposure modeling done by the EPA indicates that 93% of all benzene exposure is through inhalation (cigarette smoke, indoor offgassing, that wonderful refueling smell!), with 7% exposure through oral ingestion. So, potentially elevated levels in this 7% fraction are not likely to greatly increase exposure. In addition, the 5 parts per billion level for drinking water is set based on an assumed daily consumption of 2 liters per day (Source – USEPA), a safety factor up from the actual estimated 0.9-1.2 L per day measured consumption. Assuming the average amount of benzene in soda (mainly diet, mind you) is 4 times that of drinking water, a 500 ml dose of diet soda per day is required to equal the dose from drinking water, which mind you, only counts for 7% of the total bezene exposure. So in a sense, a person drinking 2 servings of diet soda per day would exceed the exposure from drinking water at the federally regulated level, and knock the socks off the California standard of 0.13 ppb in water. This will increase his/her known oral exposure. The total exposure to benzene of that individual, however, would not go up significantly because the overwhelming majority of the exposure still occurs through the nose, not through the mouth.

The issue here, and benzene is just the symptom, is that consumers know much more about their drinking water than they do about their manufactured food products, and that is not good for the consumer or for the industry because in the absence of knowledge and full disclosure, both parties are vulnerable. Which is why attempts to limit consumer knowledge hurt everyone.

Conclusion Please don’t stop drinking soda because of this, I am sure you can find plenty of other reasons to limit your soda consumption… Drink lots of filtered tap water, it’s the best!! And, I can assure you that most tap water is tested thoroughly, it’s zero calories and cheap!

Big Melt Threatens India’s Water — Bagla 2007 (112): 1 — ScienceNOW

The massive glaciers of the Himalayas, which hold one of Earth’s largest reserves of snow and ice, have dwindled by one-fifth in the past 4 decades. A team of Indian geologists and remote sensing experts published the alarming news this week–a grim warning that if the trend continues, it could jeopardize the fresh water supply of more than 500 million people in India

Well, still early news, the worst case scenarios come to pass if there is not enough rain during the monsoon to replenish the glaciers. Here’s a concise Yahoo Answers page compiled by an 18 year old Nicaraguan

All states will have increased rainfall except Punjab, Rajasthan, Tamil Nadu where it will decrease. Extreme precipitation will increase, particularly along the western coast and west central India.

Excerpted from the Stern report… My reading of the Stern report leads to the conclusion that global warming will increase water availability in the subcontinent, but also lead to more extreme rainfall and flood events, increased run off, more soil erosion, landslides, etc. Increased glacial melting will add to this mess. So, I don’t really like the conclusion this science article seems to come to. South Asia is not going to run out of fresh water anytime soon, it’s just going to have a hell of a time dealing with it!
