When the bacteria—which had been safely isolated from the space crew—returned to Earth, scientists injected them into mice.
They found the space-faring bacteria caused death quicker and more often than Earth-restricted organisms.
The findings are concerning for future astronauts who will embark on
longer space missions farther away from Earth-based medical help,

...When the bacteria returned to Earth, genetic sequencing showed that 167 genes and 73 proteins had been altered.
One protein, called Hfq, helped control more than a third of the
altered genes. Hfq regulates RNA—the code of bacterial life—during
stressful events. When activated, the protein previously had been shown
to strengthen several types of pathogens.
An technique called scanning electron microscopy also showed some Salmonella were starting to form biofilms, a protective slime layer.
On Earth, biofilms can grow on ship hulls and clog pipes, costing
industry billions of dollars. Biofilms also worsen some diseases and
reduce the effectiveness of many antibiotics.
Actually there are 2 Phycodurus eques in the picture. Photographed last January at the Birch Aquarium at Scripps. Sorry for the poor quality image but I have not got the knack of taking pictures through glass. I heartily recommend visiting the aquarium if you are in the La Jolla area. The Sea of Genes exhibit was very well done.
The strike has gone on for almost 2 months. What are people doing with the garbage? Some are dumping it in the parks, others with friends and relatives in nearby municipalities. We are fortunate to have a garage and a few garbage cans to stockpile away from the house. But if we were back in our old apartment in Kits we'd be screwed (particularly with the flow of dirty diapers we're generating). Some people we know are burning stuff in their fireplaces. I'm sincerely curious about how people are managing their garbage & recycling pileup.
A Vancouver woman and three of her neighbours are out $40 after being tricked by a bogus trash collector.
Tara Wohlberg told CBC News a man with a van full of garbage knocked on her door at 5 p.m. Thursday and offered to take her garbage away for $20.
She said she collected up a bag of her own trash and three from her neighbours and paid the man a total $40 to take it all away.
But the next morning, her garbage had been returned to her alley and "the rats, crows and raccoons had an all-nighter with my fish skins and cat litter," she said.
I have a soft spot for Ann Roddick - I was in grad school taking environment & business courses during the ascendancy of the Body Shop model of corporate responsibility. She cared a lot about the world in which she lived, & she will be missed.
It's starting to look alarmingly like the pursuit of biofuels will be the next poster child for the Law of Unintended Consequences - up there with thalidomide and turning cattle into cannibals. Borneo's forests have been under siege for some time by the agricultural industry, transmigrants, and the mining industry. Demands for "environmentally friendly" energy might just drive the last chainsaw to the last tree. I'm starting to think these guys have a point.
Despite government claims pristine jungles are escaping the effects
of the "green solution" to the energy crunch, the boom is threatening
the survival of animals like the endangered orangutan and turning the
country into a major global warming contributor, environmentalists say...
plantations have long been a staple of the economies of tropical
Indonesia and neighboring Malaysia. Oil made from the red, spiky
apple-sized fruit is used to make a vast range of products, from soap
to chocolate to lipstick.
But concern over pollution
from the burning of fossil fuels in Europe and the United States has
led to a new use for the oil - mixing it with diesel to make a cleaner
burning and cheaper fuel to put in cars.
EU parliament this year announced a renewed push to meet sustainable
energy targets, including mandating using biofuels to supply at least
10 percent of transport fuel needs by 2020.
by government tax breaks, many of Indonesia's largest conglomerates as
well as foreign companies are investing millions in expanding
plantations and refining facilities on Borneo, which has one of the
richest ecosystems in the world and is one of the only remaining homes
of the orangutans.
TORONTO — Publicly-funded religious schools would be allowed to teach creationism and other theories, says Progressive Conservative Leader John Tory.
Speaking to reporters at the a Jewish day school in Thornhill, Ont., on Wednesday, Mr. Tory defended his plan to bring Jewish, Islamic and other religious schools into the public education system.
“They teach evolution in the Ontario curriculum, but they also could teach the fact to the children that there are other theories that people have out there that are part of some Christian beliefs,” Mr. Tory said at the Kamin Education Centre.
While I could understand him supporting creationism within a course of religious instruction, the linking of ID or creationism to evolution in a science curriculum should cost Tory the election.
In clarifying his remarks yesterday, Mr. Tory said: "The Ontario
curriculum teaches evolution and that is the curriculum that would have
to be taught in the faith-based and all other schools that receive
public funding. There are other theories that can be taught as part of
religious instruction ... But the curriculum is the curriculum."
I'll take it at face value. I suspect that this is just a gaffe, rooted in some eagerness to pander a bit to his religious voters, and he spoke without thinking.
"Public reaction was favorable to the news that a glass of wine a day can help prevent heart attacks," Peavy said. "Of course, most people figured that eight glasses of wine a day must be better than one. And many Americans reacted well to the news that eggs probably wouldn't kill them outright. Aside from that, they've pretty much ignored every word we've ever said concerning just about everything."
Because the experts' advice was barely followed, the mass resignation is expected to have little impact on the lives of most Americans.
"Go ahead, America," Peavy said. "You don't need us. Watch all the topsoil go down the Mississippi. Transport your children in baskets on top of your SUV deathmobiles. Keep playing with your cute and cuddly pal, the atom. Press your nose against the TV screen for even more educational 3rd Rock From The Sun enjoyment. Use plentiful gasoline to burn book- readers at the stake. Don't eat anything but sugared pork lard. Do whatever you want."
