A team of researchers has engineered a live form of salmonella that can deliver a vaccine. The modified bacterium eliminates all the things you don’t want in salmonella, the leading cause of food-borne illness. It’s also designed to destroy itself so that it’s not released into the environment. In the petri-dish experiment,

An Exercise in Trend Recognition
For this edition of Future Imperfect, Sven Johnson has been grasping towards something which may or may not be there to grasp.
If you spend any amount of time straining through global news and pop culture, you’ll probably have had a similar sense of unseen patterns waiting to be discovered. But, Sven asks, what exactly occurs the moment before trend recognition? Continue reading An Exercise in Trend Recognition
Grr! Arrgh! Nearly-extinct predators make a comeback
Horror writers in search of a plot need look no further: a weasel-like predator known as the fisher is making itself right at home in your Northeast or Midwest suburbs! The mixture of eco- and morality tale make it the perfect story device, given that they were almost wiped out by trappers and foresters in the last century, but reintroduced to prey on porcupines. The New York Times describes a householder’s encounter with a fisher that tried to eat her German shepherd’s face:
“I had never seen anything like it,” Ms. Beaudry recalled. “I didn’t know what it was. It kind of looked like a fox. But it was very, very ratty looking and had fangs and claws. It was creepy looking, but not that big.”
More animals-out-of-place news: The Caribbean monk seal, extinct. The Chinook salmon, endangered in the U.S., is thriving so well in Chile and Argentina that it could disrupt freshwater and marine ecosystems. And there’s thumbnail-sized quagga mussels clogging up the Colorado River. What other displaced creatures might be cast in near-future fiction?

The Wire
Personally, I won’t believe it till I hear some guy on cable screaming about it at the top of his lungs. But how about a nanowire-mesh “paper towel” that can clean up 20 times its weight in oil, and recycle the gunk for future use? It might filter and purify water, too.
The new material appears to be completely impervious to water. “Our material can be left in water a month or two, and when you take it out it’s still dry,” [MIT materials scientist Francesco] Stellacci said. “But at the same time, if that water contains some hydrophobic contaminants, they will get absorbed.”

Making Our Future as Better Ancestors
It seems to be the custom for new Futurismic posters to introduce themselves. I don’t see race, sex, age, residence, politics, or preferences. But people tell me I’m a 53-year-old white guy who lives in Arizona, leans to the left, and likes fiction, history, journalism, science, The Loud Family and The New Pornographers, and I believe them.
The birth of yet another niece puts me in mind of Samantha Powers’ recent commencement advice: “Be a good ancestor.” One way to do that might be to start treating the environment as part of the economy, by putting a dollar value on it. A report to the U.N. Commission on Biodiversity estimates that humans do at least $78 billion worth of damage each year, “eating away at our nature capital” through deforestation and pollution. Sobering to consider that about 40% of the world economy is still based on biological products and processes.
In light of the likely first contact with an uncontacted seminomadic Amazon tribe on the borderlands of Brazil and Peru, we probably need to factor cultural diversity into the equation, too. There’s something poignant and human about that AP photo of tribespeople firing arrows at an aircraft.
Think about all our ancestors have done for us. The origin and purpose of Stonehenge is no longer a total mystery, according to recent investigations: it served as a cemetary for at least 500 years beginning 5,000 years ago. It may have functioned for 20 or 30 generations as the resting place of a ruling dynasty. At least 300 surrounding homes made it one of the largest villages in northwestern Europe.
Ancestor-worship as big business? If that’s not old enough for you, consider a 375-million-year-old ancestor called the placoderm fish, with a fossil embryo attached with an umbilical cord. It’s the oldest known instance of live birth. Now think what our moms put up with, bringing us into the world. [Image by Danny Sullivan]
