President Obama signs indefinite detention bill into law

The National Defense Authorization Act (NDAA), signed by President Obama into law Dec. 31, contains a sweeping worldwide indefinite detention provision.

?The statute is particularly dangerous because it has no temporal or geographic limitations, and can be used by this and future presidents to militarily detain people captured far from any battlefield,?? said ACLU executive director Anthony D. Romero.

The ACLU believes that any military detention of American citizens or others within the United States is unconstitutional and illegal, including under the NDAA. In addition, the breadth of the NDAA?s detention authority violates international law because it is not limited to people captured in the context of an actual armed conflict as required by the laws of war, according to the ACLU statement.

Column: Another reason you can't go home (AP)

Nearly a quarter of the major college football programs dotting the landscape will kick off next season with a new boss in charge, including a dozen that just couldn't wait to ring out the old one.

Those schools have already played, or will play, their bowl games with either an interim coach or the newly appointed coach on hand. Small wonder so many teams looked so confused.

At Texas A&M, to cite just one example, interim coach Tim DeRuyter, who had been defensive coordinator and took over for the fired Mike Sherman, accepted the head coaching job at Fresno State even before he coached the Aggies to a win over Northwestern in the Meineke Car Care Bowl last Saturday.

So maybe it's a good thing the A&M players didn't get too attached to DeRuyter, since they'll be coached next season by Kevin Sumlin, who, coincidentally, bailed on his kids at Houston just ahead of their bowl.

There's too much money and too little loyalty to go around in college football these days, unless you happen to be a "student-athlete." Then there's no money, but plenty of loyalty expected on your end of the bargain ? something Tennessee freshman DeAnthony Arnett is likely to be reminded of in the next few days.

Arnett's request for a transfer, as well as Tennessee's response so far, differs from dozens of similar cases only in the details.

After being one of the top-ranked prep receivers in the country, the Saginaw, Mich., native committed to the Volunteers and last fall caught 24 passes as a freshman.

By all accounts, he was happy with his coaches, staff and teammates and the feelings were mutual. Then he asked to be released from his commitment at Tennessee so he could transfer to Michigan or Michigan State and be closer to his ailing father, who's undergone two surgeries since Arnett returned home for winter break and might need a third.

Tennessee initially said it would not release Arnett to play at either Big Ten school ? meaning he would have to sit out at least a season before playing for either ? but offered to do so if Arnett chose to play at one of the Mid-American Conference schools in the state ? Central Michigan, Western Michigan or Eastern Michigan.

Though school officials won't take the matter up again until Tuesday at the earliest, a spokesman for Tennessee said Monday the decision wasn't likely to change. Despite making free agency possible for coaches, doing the same for players is currently the game's worst nightmare.

"While our policy is not to release student-athletes to schools we compete or recruit against, there are a number of schools to which we will release DeAnthony that will keep him near his family, allow him to play Division I football, and afford him the opportunity to receive a quality education," he said.

Tennessee looks heartless, but the school is simply playing by the unwritten rules of the game.

While the major programs can't do anything to slow the comings and goings of coaches, they can draw the line with players. That's why you'll almost never see a kid who played for one of the schools in a Bowl Championship Series automatic-qualifying conference playing the following season for a different one.

And to be fair, while the Vols haven't scheduled a game against any Big Ten school in 10 years, and none are on next season's schedule, either, they did compete against the two Michigan schools to recruit Arnett a year ago and again this year, when they got a verbal commitment from another top-ranked Michigan native, Dan O'Brien.

A member of Arnett's family told the Saginaw News that Arnett wouldn't return to Tennessee or comment until the situation is resolved, but he's got precious little leverage.

Arnett is still technically on scholarship and the letter of intent he signed requires him to complete at least one year of schooling at Tennessee, a requirement he may try to meet by taking online classes offered by the school during the spring.

If Arnett is successful, either he or the school he chooses could petition the NCAA for a waiver, which would allow him to play somewhere else next season. Otherwise, the same family member told the newspaper, he may have to pay his own way to attend college, sit out a year, lose a year of eligibility ? or some combination of the three.

"The people at Tennessee know he's not coming back. The coaches know, the players know, the administrators know. No matter what happens, Dee can't go back right now, not the way the situation is," the family member said. "They know that. We've been talking back and forth. They understand."

If the Vols don't, they certainly should, since there is a precedent close to home. Though Tennessee struggled to a disappointing 5-7 season under coach Derek Dooley, the team caught a small break when offensive lineman Alex Bullard joined the team this season.

Bullard, from suburban Nashville, transferred in from Notre Dame after the death of his father so he could be closer to the rest of his family. Irish coach Brian Kelly released him from his scholarship, and the NCAA granted him a waiver to play immediately.

Weighing the Positives

Image: Mehau Kulyk/Photo Researchers, Inc.

It seems like every few months a new study points out the inefficacy of yet another wide-scale cancer screening. In 2009 the U.S. Preventive Services Task Force sug?gested that many women undergo mam?mograms later and less frequently than had been recommended before because there seems to be little, if any, extra benefit from annual tests. This same group recently issued an even more pointed statement about the prostate-specific antigen test for prostate cancer: it blights many lives but overall doesn?t save them.

More recently, researchers at the Dartmouth Institute for Health Policy and Clinical Practice announced that just because a mammogram (almost 40 million are taken every year in the U.S.) detects a cancer does not mean it saves a life. They found that of the estimated 138,000 breast cancers detected annually, the test did not help the vast majority of the 120,000 to 134,000 women afflicted. The cancers either were so slow-growing they did not pose a problem, or would have been treated successfully if later discovered clinically, or else were so aggressive that little could be done about them. Chest x-rays for lung cancer and Pap tests for cer?vical cancer have come under simi??lar criticism.

Individual cases dictate what tests and treatment are best, of course, but one factor underlying all these tests is a bit of numerical wisdom that, though well known to mathematicians, bears repeating: when one is looking for something relatively rare (not just cancer but even for, say, terrorists), a positive result is very often false. Either the ?detected? life-threatening cancer is not there, or it is of a sort that will not kill you.

Rather than looking at the numbers for the prevalence of the above cancers and at the sensitivity and specificity of each of the tests mentioned, consider for illustration cancer X, which, let us assume, afflicts 0.4 percent of the peo?ple in a given population (two out of 500)
at a certain time. Let us further assume that if you have this cancer, there is a 99.5 percent chance you will test positive. On the other hand, if you do not, we will assume a 1 percent chance you will test positive. We can plug these numbers into Bayes? theorem, an im?portant result from probability theory, and get some insight, but working directly through the arithmetic is both more illustrative and fun.

Con?sider that tests for this cancer are administered to one million people. Because the prevalence is two out of 500, approximately 4,000 (1,000,000 x 2/500) people will have it. By assump?tion, 99.5 percent of these 4,000 people will test positive. That is 3,980 (4,000 x 0.995) positive tests. But 996,000 (1,000,000 ? 4,000) of the people tested will be healthy. Yet by assumption, 1 percent of these 996,000 people will also test positive. That is, there will be about 9,960 (996,000 x 0.01) false positive tests. Thus, of the 13,940 positive tests (3,980 + 9,960), only 3,980/13,940, or 28.6 percent, will be true positives.

If the 9,960 healthy people are sub?jected to harmful treatments ranging from surgery to chemotherapy to radi?ation, the net benefit of the tests might very well be negative.

The numbers will vary with different cancers and tests, but this kind of trade-off will always arise in that nebulous region between psychology and mathe?matics. A life saved because of a test, though not that common, is a much more psychologically available outcome than the many substantial, yet relatively invisible, ill effects to which the test often leads.

Monkey business: Thieves swipe primate from California zoo

By the CNN Wire Staff

updated 3:49 AM EST, Sat December 31, 2011

STORY HIGHLIGHTS

  • Banana-Sam is 17 years old and has been in the zoo's care for years
  • His keepers warn that he needs a special diet and the company of his own kind
  • Common squirrel monkeys can give a nasty bite that can quickly become infected

(CNN) -- Concern was growing Saturday for the welfare of a much-loved male squirrel monkey stolen from an enclosure at San Francisco Zoo in California.

Zoo workers discovered the theft Friday morning, when they found a back perimeter gate had been breached and two holes cut in the mesh fence of the squirrel monkey exhibit.

The missing monkey, known as Banana-Sam to his keepers, is 17 years old, over 12 inches tall and weighs about 2 lbs.

But his keepers warn that while he looks very cute, he is not a pet -- and can deliver a nasty nip.

"He has extremely sharp teeth and will definitely bite if provoked, which can cause infections right away," the zoo said.

Primate curator Corinne MacDonald told CNN affiliate KTVU she was very worried about Banana-Sam's well-being.

"Stress can actually kill a monkey that small," she said. "They are highly social animals and should not be alone, and he's got cage-mates here that he's lived with almost all his life that are his friends, so to speak, that he needs to be with."

The monkey needs a specialized diet to stay healthy and is fairly elderly for his species, making him more vulnerable, the zoo says.

Police are investigating the theft, but surveillance cameras at the zoo did not capture it on film.

What motivated the thieves to swipe the monkey is not clear. While common squirrel monkeys are not endangered, they can be found at pet trade markets -- which is illegal in California, the zoo says -- or medical research institutions.

"I just want the animal back. I don't really care why they did it," MacDonald said.

An unknown person was quick to set up a fake Twitter account in Banana-Sam's name, following in the path of a cobra that escaped at New York's Bronx Zoo in March. The snake's mock Twitter account, with humorous tweets on its supposed whereabouts in New York City, swiftly attracted a large online following.

Under the handle @SF_BananaSam, the "monkey" is now tweeting his way round San Francisco.

"Went to monkey bars in Golden Gate Park playground, left disappointed. #nobananadaiquiri" one post reads.

Another says: "I'm a funny-looking vegan who ran away from home and who people follow on Twitter. IN other words, A NORMAL SAN FRANCISCAN."

Anyone with information on Banana-Sam's whereabouts is urged to call San Francisco police.
