Star will explode in gamma ray burst, dooming all life

Filed under: Science

We're doomed! The Mayans were right about that whole "world ending on Dec. 21, 2012" thing!

Okay, probably not. Inevitably, though, this star will explode into a supernova. That's just fine, given that it's too far away for such an event to pose a threat. If it collapses in a particular type of supernova called a gamma ray burst, though ...

Scientists build a big machine in a deep, dark Minnesota hole

Filed under: Science

"It's dark as a dungeon, way down in the mine" goes the well-worn working class folk ballad. At the long-dormant Soudan mine in the Iron Range--the scene of dramatic strikes and bloody clashes in the early 20th century--physicists from Stanford, MIT and the UofM have been looking for a piece of history that is darker still: the "dark matter" that is said to make up 25% of the universe.

Minnesota's Abby and Brittany Hensel, conjoined twins, make Newsweek

Filed under: Science

I still remember the day I walked in on my wife staring raptly at the TV screen. I followed her gaze and was stunned to see a girl who appeared to have two heads. In fact, it was conjoined twins Abby and Brittany Hensel, two of the most remarkable people in Minnesota.

I was reminded of this today as I flipped through the new issue of Newsweek and saw a picture of the Hensel twins in a swimming pool. They were mentioned at the tail end of an article called Reality's Believe It or Not. Here's the part of the article concerning the Hensel twins:

You hear a lot of mixed emotions from the stars of these shows—none of whom, by the way, is paid to appear. Abby and Brittany Hensel allowed the world to watch them take their driving test, even while the conjoined twins—they have two heads but one set of arms and legs—decided who would control the gas (Abby) or the blinker (Brittany). "Abby and Brittany Turn 16" is handled with great care, the girls are given plenty of time to talk about their anatomy in nonsensational ways. They explain that they made the film "so people wouldn't have to always stare and take pictures. Cause we don't like it when they take pictures … so they just know who we are and stuff." But as the film progresses, you see that any time the twins leave their Minnesota town, people blatantly photograph them, leaving the girls feeling "violated," according to their mother, Patty. She gets teary in the documentary when she explains how she doesn't want her girls to grow up like circus performers, and she hasn't let the girls speak to the media since the movie debuted two years ago. Watch the movie now—it's still in heavy rotation on the Discovery Health network—and you can see why they'd shun the spotlight. It's hard to shake the creepy, voyeuristic feeling you get when you watch the girls make pottery or brush each other's hair. The narrator explains that they are, "in nearly every sense, perfectly normal teenagers." But we know we're watching precisely because they're not.

Burnsville resident responsible for Celine Dion's "magic baby"

Filed under: Science

Christopher Roller has proof of paranormal activities: the magic tricks of David Copperfield. "David admits he's using godly powers--that's paranormal," Roller writes in a lawsuit filed last month in U.S. District Court. "Paranormal events are occurring on planet Earth by David Copperfield and probably by most illusionists (magicians)."

The Burnsville resident is seeking $1 million from the James Randi Educational Foundation. The Amazing Randi--best known for exposing spoonbender Uri Geller as a fraud on The Tonight Show in 1973--has long offered a $1 million prize for anyone who can provide evidence of any "paranormal, supernatural, or occult power or event." No one has ever successfully claimed the money.

This binge brought to you by Ambien

Are you cackling at today's stories about the middle-of-the-night adventures being reported by Ambien users? According to the Washington Post, Minnesota researchers have compiled numerous reports of people eating, talking, walking, and wreaking havoc while asleep. Other stories tell of people waking up surrounded by empty Doritos bags and half-eaten loaves of bread. The New York Times story on the study described a woman who gained 100 pounds before she was willing to consider her family's bizarre claims about her nighttime eating.

Our mild January: Winners and losers in the wild kingdom

Filed under: Science

February 1 marked the tenth anniversary of the coldest temperature ever recorded in Minnesota. The minus 60 degree reading (measured in the Arrowhead town of Tower) produced a weird sort of provincial glee. If memory serves, one enterprising television reporter demonstrated the extremity of the cold--and presumably, the hardiness of Minnesotans--by spraying water in the air; the droplets froze solid before they hit the ground. Even though you probably watched the spectacle from the comfort of the couch, you couldn't help but feel a little bad ass for living here.

What a difference a decade makes. In the wake of the warmest January on record, there is not much to boast about. And aside from the occasional snowmobile or SUV dropping through thin lake ice (oh, and the prospect of calimitous global climate change), there really wasn't much to gripe about either.

One more way profits trump science in drug trials

The author of the highly literate and widely lauded 2003 book, "Better than Well: American Medicine Meets the American Dream," Carl Elliot is well positioned to comment on pharma's ceaseless search for new maladies--which can, of course, then be treated profitably. In today's Slate, Elliot, who is a professor at the University of Minnesota's Center for Bioethics, has co-authored a terrific piece on the mechanics and dangers of allowing researchers conducting clinical drug trials to hire their own for-profit overseers.

Playing Twister in Minnesota

Filed under: Science

Here at City Pages, we get a lot of junk emails from companies hoping to hype a product. Once in a crescent blue moon, one comes along that strikes our fancy.

According to the SATT (Site Assessment of Tornado Threat) software 3.0 utilized by VorTek LLC out of Huntsville, Alabama, the most tornado-prone spot in Minnesota is less than a half-mile west of State Highway 111 and approximately three-fifths of a mile north of U.S. Highway 14 near Nicollet. From 1950 through 2004, a whopping 54 tornado track segments have touched down or passed within 20 miles of that point, including two F3's and three F4's.

The sixth wave of extinction: the Minnesota edition

Filed under: Science

Among biologists, other scientists and anyone else who bothers to pay attention, it's no secret that plants and animals are vanishing from the earth at an appalling pace. The sixth wave of extinction, as the trend is referred to, is occurring far more rapidly than five extinction waves that preceded it. By some estimates, approximately 40 species of plants and animals disappear from the earth every day. There is scant mystery as to the cause: a nasty invasive species, the savvy ape, has crowded the globe, gobbled up most of its resources, and fouled its water and air.

Global warming is a hoax! Those moose are just pretending to die

Filed under: Science

For anybody interested in Minnesota's native fauna, one of the most disturbing trends of recent times has been the dramatic collapse of the state's once-robust moose population. The numbers tell the story. In 1985, the moose herd in northwest Minnesota was estimated at approximately 4,000 animals. The most recent surveys place the count at fewer than 300.

For about a decade, researchers have struggled mightily to find an explanation for the spike in mortality rates. To do so, they placed radio collars on some 152 animals, collected road kills, and performed about 160 autopsies. The conclusion? In a nutshell, the moose are dying off because of climate change.

WSJ on the environmental damage wrought by Katrina

Filed under: Science

There's a superb story by Ken Wells in last Friday's Wall Street Journal titled "Oil, Saltwater Mar Louisiana Coast, Threaten Future." Here are some salient excerpts:

[A]t least 193,000 barrels of oil and other petrochemicals were blown or driven by tides across the fragile marshy ecosystems and dense urban areas of the Plaquemines and St. Bernard Parishes, southeast of New Orleans.... The spills... approach the scale of the famous 1989 Exxon Valdez tanker spill, which dumped 240,000 barrels of crude oil....

Coastal Louisiana's wetland produces a third of the nation's commercial seafood--about a billion pounds of fish, crab and oysters annually--the most in the lower 48 states.... The mixture of sewage, rotting vegetation and oil... has been devastating to aquatic birds. More than 5 million migratory birds, including a number of rare and endangered species, make use each year of the Louisiana estuary's marshes, swamps, bays and bayous. Coastal Louisiana also harbors the largest nesting population of bald eagles in the lower 48....

Coastal Louisiana holds the earth's seventh largest wetland and is America's largest estuary, containing 30 percent of all U.S. coastal marshes... Yet the state's coastal ecosystem is less well known than places such as Chesapeake Bay, whose fishery production it dwarfs. It receives far less adulation than the Florida Everglades, though it shelters far more species of wildlife, fish, and birds.

Some scientists... are convinced that the conditions of the wetlands of the St. Bernard and Plaquemines Parishes contributed to the number of oil spills [at least 40, ten of which are major] during Katrina. One example: Pipelines originally buried under the marsh 20 years ago had become more vulnerable to Katrina's surges as the landscape changed... [T]he Plaquemines Parish president says he heard of cases where "the force of the storm surges forced a lot of pipelines to the surface, snapping them like sticks of dried spaghetti."

Who says the papers never print any good news?

This report on the nation's youth from today's Washington Post:

Study: Half Teens Had Oral Sex

Slightly more than half of American teenagers, ages 15 to 19, have engaged in oral sex, with females and males reporting similar levels of experience, according to the most comprehensive national survey of sexual behaviors ever released by the federal government.

The report today by the National Center for Health Statistics shows that the figure increases to about 70 percent of 18- and 19-year-olds.

The research suggests that abstinence programs have shifted kids' sexual practices to non-intercourse activities. In fact, a quarter of all "virgin" teens have engaged in fellatio or cunnilngus.

In a detail that only a Marxist or a guidance counselor at Edina High could explain, oral sex is most popular among white teens whose families are in the uppper income brackets.

New Orleans: what's in the water?

Filed under: Science

Bodies, fuel, heavy metals, industrial chemicals, bacteria, gasoline from cars and up to 6,000 gas storage tanks in the city, garbage, sewage.

--list of contaminants from WWL-TV live webcast

Searchers were armed with proof of what many holdouts had long feared: The floodwaters are thick with sewage-related bacteria that are at least 10 times higher than acceptable safety limits. The muck contains E. coli, certain viruses and a type of cholera-like bacteria....

The danger of infection wasn't limited to the New Orleans area. The bacteria is feared to have migrated to crowded shelters outside the state, where many evacuees are staying. Four deaths - one in Texas, three in Mississippi - have been attributed to wound infections, said Tom Skinner, spokesman for the CDC.

--Associated Press

Toxicologists and public health experts warned yesterday that pumping billions of gallons of contaminated water from the streets of New Orleans back into the Gulf of Mexico - the only viable option if the city is ever to return to even a semblance of its former self -would have a crippling effect on marine and animal life, compromise the wetlands that form the first line of resistance to future hurricanes, and carry deleterious consequences for human health throughout the region....

The waters now swilling around the streets and neighbourhoods of New Orleans will probably end up either in the Mississippi River or in Lake Pontchartrain, just to the north of the city, where they are likely to react with the oxygen in the water and deprive all living creatures, starting with the fish, of the means to life.

"We're looking conceivably at zero-dissolved oxygen, which will lead to the death of fish and other organisms," Dr Zeliger said. "If the migratory birds who pass through the area find any fish to eat, they will be contaminated so the birds will start dying in large quantities ... Reptiles and snakes are going to be driven out of their nests and habitats, which has implications for human safety. We're going to see water moccasins [a highly venomous snake], which are nasty critters, and alligators threatening people."

--The Independent (London)

As engineers began pumping out the Big Easy this week, creating small but visible wakes of water behind street signs and tree trunks, the water they're moving carries a volatile mix of everything imaginable - from household paints, deodorants, and old car batteries to railroad tank cars, sewage treatment plants, and landfills. While state officials stop short of calling it a toxic soup, at least so far, federal environmental officials call it catastrophic....

Meanwhile, a warehouse explosion along the river in New Orleans and an oil spill several days after the hurricane passed through have added to the challenge. "Everywhere we look there's a spill," said Mike McDaniel, secretary of Louisiana's Department of Environmental Quality, in the state's first major assessment of hurricane Katrina's environmental impact. "There's almost a solid sheen over the area right now."

--Christian Science Monitor

Tests of water covering New Orleans showed excessive levels of E. coli bacteria and lead, federal officials said Wednesday, providing the first confirmation that the floodwaters caused by Hurricane Katrina are posing health risks for emergency response workers and residents who have remained in the city.

While neither substance has been blamed for any deaths, a spokesman for the Centers for Disease Control and Prevention said state and local officials had reported three deaths in Mississippi and one in Texas from exposure to Vibrio vulnificus, a choleralike bacteria found in saltwater that poses special risks for people with chronic liver problems.
