Of the roughly 30 species of parrots now breeding in the United States, only monks colonize in colder climates, and thus are “the only ones in New York City,” said Stephen Pruett-Jones, a professor of ecology and evolution at the University of Chicago, who has studied them in Hyde Park for 25 years.
The first published citing of the species (Myiopsitta monachus) in the wild in America was in New York in 1967, he said. Newspaper accounts put them in Chicago the following year, and in Florida in 1969.
By 1970, there was the odd parrot sighting in New York: a few at Riis Park, a handful in the Rockaways, some more on Staten Island. A nest, but no birds, was found in Central Park, in a broken floodlight behind the Metropolitan Museum of Art.
Their locations were pinpointed, but it was less clear how they got here. No biologist believes they flew here on their own.
Some take Ms. Lynch’s view: They escaped from the airport. Others see less swashbuckling beginnings: Owners sick of their rasping cries set them free. Marc Morrone, who owns Parrots of the World, a pet store in Rockville Centre, on Long Island, says neither explanation is valid. The airport story is an “old wives’ tale,” he said, because shipping containers do not tend to break, and the birds make “wonderful” pets, so why would anyone set them free?

or rabbis, the first question is: Is it kosher? Certainly, there are many Jewish legal hurdles test-tube meat would have to clear before a definitive answer could be reached. A central point of debate is the origin of the cells, which some say would have to come from a kosher—that is, cloven-hoofed, cud-chewing—animal. “As a general principle, something derived from a nonkosher animal is not kosher,” says Rabbi Menachem Genack, head of the Orthodox Union’s Kosher Division.
Others, such as Rabbi Carl Feit, chair of the biology department at Yeshiva University, say cultured meat could still be kosher even if the donor animal isn’t. Feit points to the Jewish legal principle of nullification, which states that a trace amount of a forbidden substance can be fully absorbed into an acceptable one without rendering the second treif, or forbidden. If, for example, a piece of meat falls into a glass of milk, the milk is still considered kosher as long as the meat is not more than one-sixtieth of the mixture.
A primary application for many smartphone users is photography. Photo quality has improved a lot and most people aren't terribly demanding, but physics limits what a camera can do. Panasonic is exploring what a communication enabled camera can do with the Lumix CM1 - what if a smartphone was more along the line of a high end pocketable camera.
It is unlikely to have a huge market - for most people it is probably a bad idea. But something like this may be just the thing for those who find smartphone photography lacking and recognize the best camera is the one you are carrying.
The mere suggestion that the league's booming popularity could ever be vulnerable to a slowdown would be scarier outside of league headquarters. The companies who do the most business with the NFL operate in industries that have been disrupted by competitors and new technology. Those companies are clinging to the NFL and their massive fanbase as they were a lifeboat.
The NFL, as it stands, props up TV networks, who have been broadsided by Netflix, among others. If viewership dipped, they would no longer be able to hike up affiliate fees to local stations, which give them a dual revenue stream, along with advertising, and are almost directly tied to football. Those inside the industry say this sort of chain reaction could—no exaggeration—cause the downfall of the entire television industry. Television networks would have to find something that could possibly deliver 17 million viewers on on a consistent basis. Spoiler alert: They can't. The power the league has over broadcasters was clear when CBS took their popular Thursday Night comedy lineup and pushed it aside as if they were cable access shows. "The Big Bang Theory" is now on Mondays. The NFL anchors Thursday nights. And Sundays.
Everyone agrees that if the NFL took a hit, there's no logical replacement. The Pro Bowl, the league's afterthought of an All-Star game, draws better ratings than nearly all baseball and basketball playoff games.
We’ve known for some time that multi-tasking is bad for the quality of cognitive work, and is especially punishing of the kind of cognitive work we ask of college students.
This effect takes place over more than one time frame — even when multi-tasking doesn’t significantly degrade immediate performance, it can have negative long-term effects on “declarative memory”, the kind of focused recall that lets people characterize and use what they learned from earlier studying. (Multi-tasking thus makes the famous “learned it the day before the test, forgot it the day after” effect even more pernicious.)
People often start multi-tasking because they believe it will help them get more done. Those gains never materialize; instead, efficiency is degraded. However, it provides emotional gratification as a side-effect. (Multi-tasking moves the pleasure of procrastination inside the period of work.) This side-effect is enough to keep people committed to multi-tasking despite worsening the very thing they set out to improve.
On top of this, multi-tasking doesn’t even exercise task-switching as a skill. A study from Stanford reports that heavy multi-taskers are worse at choosing which task to focus on. (“They are suckers for irrelevancy”, as Cliff Nass, one of the researchers put it.) Multi-taskers often think they are like gym rats, bulking up their ability to juggle tasks, when in fact they are like alcoholics, degrading their abilities through over-consumption.

What is a minimal set of identifiers that you can uniquely identify someone with? What is the average? One can imagine categories - those that are based on physical attributes, those based on experiences, and so on... It can make an interesting party game.
