The wage gap between college-educated workers and those with just a high school diploma has been growing — and accelerating. But the education gap is also doing something unexpected: clustering workers with more education in cities with similar people
. "This effectively means that college graduates in America aren't simply gaining access to higher wages. They're gaining access to high-cost cities like New York or San Francisco that offer so much more than good jobs: more restaurants, better schools, less crime, even cleaner air." Most people are aware of the gentrification strife occurring in San Francisco, but it's one among many cities experiencing this. "[Research] also found that as cities increased their share of college graduates between 1980 and 2000, they also increased their bars, restaurants, dry cleaners, museums and art galleries per capita. And they experienced larger decreases in pollution and property crime, suggesting that cities that attract college grads benefit from both the kind of amenities that consumers pay for and those that are more intangible." The research shows a clear trend of the desirable cities becoming even more desirable, to the point where it's almost a necessity for city planners to lure college graduates or face decline.Read Replies (0)

In the wake of two potentially deadly accidents, the CDC yesterday announced the temporary closure of both the anthrax and flu research labs
at the agency's Atlanta headquarters. The New York Times reports:
In one episode last month, at least 62 C.D.C. employees may have been exposed to live anthrax bacteria after potentially infectious samples were sent to laboratories unequipped to handle them. Employees not wearing protective gear worked with bacteria that were supposed to have been killed but may not have been. All were offered a vaccine and antibiotics, and the agency said it believed no one was in danger. “We have a high degree of confidence that no one was exposed,” said Dr. Thomas Frieden, the C.D.C. director. Credit David Goldman/Associated Press In a second accident, disclosed Friday, a C.D.C. lab accidentally contaminated a relatively benign flu sample with a dangerous H5N1 bird flu strain that has killed 386 people since 2003. Fortunately, a United States Agriculture Department laboratory realized that the strain was more dangerous than expected and alerted the C.D.C. ... The anthrax and flu labs will remain closed until new procedures are imposed, Frieden said. For the flu lab, that will be finished in time for vaccine preparation for next winter’s flu season, he said.Read Replies (0)

As reported by National Geographic, intelligence in chimpanzees appears to be strongly heritable
, according to research led by William Hopkins, a primatologist at the Yerkes National Primate Research Center in Atlanta, Georgia, who examined both genetic and environmental factors for a group of related chimpanzees with varying measured intelligence:To find out how much of that variability is due to genetics, Hopkins and his team assessed the cognitive abilities of 99 captive chimpanzees. They used a battery of 13 tests measuring various manifestations of intelligence, such as how the animals dealt with the physical world, reacted to sound, and used tools.
The group of chimps tested had an expansive family tree, ranging from full siblings to fourth and fifth cousins. This allowed the researchers to calculate how well scores on cognitive traits aligned with genetic relatedness. Two categories of tasks were significantly heritable: those related to spatial cognition, such as learning physical locations, and those that required social cognition, such as grabbing a person's attention. Some chimps are quite clever, making kissing sounds or clapping their hands to draw an experimenter's attention, Hopkins said. "This one is a real measure of intelligence and innovative behavior."

Watches that do more than tell the time have been around for a long time
. (And in fiction, James Bond, Dick Tracey, and Michael Knight all had notably high-tech watches.)
The new smart watches from Samsung and LG, without a phone connected via Bluetooth as backhaul, can still serve to show the time and to serve as alarms (and Samsung's can measure your pulse, too), but all the magic features (like searching by voice via the watch) do require a connection. They can't play MP3s
or take pictures
on their own, and they don't have built-in GPS
. Even so, compared to the polarizing Google Glass, the new breed of smart watches are wearables that probably are an easier sell, even if this far the trend has been to replace watches with smart phones. (Android Wear has gotten a lot of attention, but Microsoft has their own upcoming
, and Apple almost certainly does, too
.) Are you interested in a smart watch, and if so, what uses do you want it for? If they have no appeal to you now, are there functions that would make you change your mind on that front?Read Replies (0)

Scientific American reports that Wichita Falls, Texas
has taken an unusual step, precipitated by the years-long drought that Texas has faced: it's using treated sewage for drinking water
. From the article: To launch what it calls its "Direct Potable Reuse Project," the city pipes water 12 miles from its wastewater treatment plant to this treatment facility where it goes through microfiltration. A pump pulls water through a module filled with fibers that removes most of the impurities. Then it is forced through a semi-permeable membrane that can remove dissolved salts and other contaminants. The process, called reverse osmosis, is used by the U.S. military, in ships and in the manufacture of silicon chips. The water then gets blended with lake water before going through the regular water treatment system. ... At 60 cents per 1,000 gallons, it's far cheaper than any other source of water, [Wichita Falls' public works director Russell] Schreiber said. ... He said there have been few complaints so far. A glass of the finished product, sampled at a downtown restaurant, tasted about average for West Texas.

The Washington Post reports that, "In a 3-2 vote along party lines Friday, the FCC greenlit a plan to spend $2 billion over the next two years
on subsidies for internal networks. The move also begins a process to phase out some subsidies under the federal program, known as E-Rate, for services and equipment that are on the decline, such as pagers and dial-up Internet service." That sounds like a lot of money, and it is, but as usual in politics it's the result of a messy process:The original plan called for spending $5 billion on WiFi over five years, in line with a push by the Obama administration to bring next-gen broadband and WiFi to 99 percent of students over the same period. Those funds would have partly come from savings as a result of transitioning away from supporting legacy technologies. The proposal would also have eliminated an existing requirement that E-Rate funds be spent first on broadband services before being applied to WiFi. In past years, the cost of broadband service meant that money was rarely left over for upgrading WiFi connections. But the FCC's proposal was ultimately scaled back late Thursday amid Republican objections that the E-Rate program can't afford the changes. The final proposal's two-year, $2 billion commitment accounts for the money the FCC has already set aside for WiFi upgrades, but it does not commit the FCC to funding WiFi upgrades at that same rate for the following three years.
