Russia urges quick missile defense deal with US (AP)

MOSCOW ? Russia's foreign minister says a deal with the United States that would assuage Moscow's concerns about its missile defense plans is still possible, but time is running out.

Sergey Lavrov reaffirmed Wednesday that Moscow will take retaliatory action if moves by Washington to deploy missile shield components around Europe pose a threat to Russia.

The U.S. says its planned missile shield is aimed at deflecting potential missile threats from Iran, but Russia believes that the missile shield will eventually become powerful enough to undermine Russia's nuclear deterrent.

Moscow agreed in 2010 to consider NATO's proposal to cooperate on the U.S.-led missile shield, but the talks have run into a deadlock over how the system should be operated. Russia has insisted that it should be run jointly, which NATO has rejected.

Fruit flies watch the sky to stay on course

ScienceDaily (Jan. 17, 2012) ? Insects, equipped with complex compound eyes, can maintain a constant heading in their travels, some of them for thousands of miles. New research demonstrates that fruit flies keep their bearings by using the polarization pattern of natural skylight, bolstering the belief that many, if not all, insects have that capability.

"If you go out in a field, lie on your back and look up at the sky, that's pretty much what an insect sees," said Michael Dickinson, a University of Washington biology professor. "Insects have been looking up at this view forever."

Dickinson is the senior author of a paper providing details on the findings, published Jan. 10 in the journal Current Biology. The lead author is Peter Weir, a doctoral student at the California Institute of Technology.

The researchers noted that insects such as monarch butterflies and locusts maintain a constant heading while migrating thousands of miles across continents, while bees and ants hunting for food successfully find their way hundreds of feet back to the nest without a problem. That has led scientists to believe that the animals must possess a compass of sorts.

To assess how insects orient themselves, Weir and Dickinson examined the behavior of Drosophila melanogaster, a species commonly referred to as a fruit fly, in outdoor lighting conditions in a specially designed "arena" atop a building tall enough to be higher than treetops and other visual landmarks.

The researchers used a light-cured glue to attach the insects to a metal pin, which was then placed within a magnetic field that allowed the flies to move and rotate naturally but held them in place. Digital cameras tracked flight headings.

During the hour before and the hour after sunset, the headings of flies relative to the position of the arena were recorded for 12 minutes. The arena was rotated 90 degrees every three minutes, and when natural light was not altered by optical filters some of the flies compensated for the rotations and maintained a consistent heading.

When the arena was covered with a circularly polarizing filter, eliminating natural linear polarization light patterns, the flies did not shift their heading significantly in response to arena rotations.

The results indicate Drosophila has the ability to coordinate eye and brain functions for rudimentary navigation using light polarization patterns, the researchers concluded. The flies are able to hold a straighter course under normal polarization patterns than they can when those patterns are shifted.

The next step in the research is to try to determine why the flies select a particular heading.

"It's been very hard to study these processes because animals such as butterflies and locusts used in previous studies are not standard lab models," Dickinson said. "We know something about the processes, but not that much."

Demonstrating that fruit flies can navigate using cues from natural skylight makes it easier to use genetics research to better understand the complex capability and exactly how it is implemented in the brain.

For millennia, seafarers have depended on the sun to know their position in the world, but often the sun is not visible. Polarization vision solves that problem, Dickinson said, because if there's even a small patch of clear sky in a fruit fly's very broad range of view then the natural light patterns can provide location information.

He noted that fruit flies "achieve remarkable functionality" with limited resources in their brains. There are 300,000 neurons in a fruit fly's brain, and it would take 300,000 fruit flies to reach the equivalent number of neurons in the human brain.

"A lot of our research is focusing on how the fruit fly brain is multitasking in space and time to achieve remarkable effects," Dickinson said.

The research is funded by the National Science Foundation and the National Institutes of Health.

The Future Is for Fools

Image: Illustration by Chris Whetzel

As a tech columnist, I?m often asked to speak about the future of technology. Well, sure. Who doesn?t want to know what the future holds? Yet I?d be in much better shape if I were asked to predict the future of politics or bass fishing. Because nothing changes faster, and more unpredictably, than consumer technology.

Everybody who takes a stab at these kinds of predictions inevitably winds up looking like an idiot. Surely you?ve seen these things go around by e-mail: ?I think there is a world market for maybe five computers,? said the chairman of IBM in 1943. ?This ?telephone? has too many shortcomings to be seriously considered as a means of communication,? went an 1876 Western Union internal memo. ?Who the hell wants to hear actors talk?? asked Harry M. Warner (one of the Warner Brothers) in 1927.

It?s not predictions in general that will get you into trouble, though. The danger lies in predicting that things can?t be done or will never work. Those are the forecasts that will make you look shortsighted.

In general, it?s much safer to predict things that will happen. If you?re right, you?ll look like a genius. Take Jules Verne, whose articles and stories described electric submarines, TV news, solar sails, ?phonotelephote? (video calling), ?atmospheric advertisements? (skywriting) and ?electronic control devices? (tasers).

Or Arthur C. Clarke?s ?newspad? (iPad), Ray Bradbury?s ?thimble radios? (earbuds), Isaac Asimov?s pocket calculators and George Orwell?s security cameras.

And if you?re wrong, well, who can blame you? After all, if you predict something that hasn?t come true, you can always cover yourself by adding ?yet.?

So the first rule of making tech predictions is this: make predictions about things that will come to pass, not about things that won?t.

Here?s the second rule: history is going to repeat itself. Experience has shown, over and over again, that certain trends are virtually inviolable.

For example, black-and-white formats always go to color: photographs, TV, movies. So back in 1970 you could have confidently predicted the proliferation of color newspapers.

In addition, analog formats always go digital. Audio, video, photos. So in 1990 you could have safely predicted the dawn of digital TV and e-book readers.

We know that Internet access is becoming more ubiquitous, and more gadgets are getting online. Thus, you?re safe describing a future where things that currently aren?t generally online will be, like cars, kitchen appliances and clothing.

If you insist on predicting the demise of things, stick to extrapolating from obvious trends. Look at the way recent college graduates live and assume that they are the future. They don?t subscribe to printed newspapers. They don?t sign up for home phone service. They film with phones or still cameras instead of camcorders. They download their movies.

They expect to get everything on demand?songs, books, magazines, newspapers, TV shows, movies?and you?d be foolish to bet against that trend.

But what about specific products? Is there any way to predict what we?ll be carrying in our pockets in 2020? Can anyone see the next iPhone, iPad or Wii?

Probably not. If they could, electronics companies wouldn?t release flopperoos like Microsoft Zune, the BlackBerry PlayBook and the Iridium satellite phone.

In the end, it?s a blessing we can?t predict the future of tech?because it means we?ll keep trying. If we don?t know if something will succeed or fail, we?ll keep innovating. We?ll heed the words of Alan Kay: ?The best way to predict the future is to invent it.?

Hose laid for fuel transfer at iced-in Alaska town (AP)

ANCHORAGE, Alaska ? Crews have begun transferring 1.3 million gallons of fuel from a Russian fuel tanker to the iced-in western Alaska city of Nome.

Stacey Smith of Vitus Marine says the offloading began around sundown Monday. Vitus is the fuel supplier that arranged to have the Russian tanker Renda and its crew deliver the fuel.

Earlier, crews laid two hoses for the transfer along a stretch of Bering Sea ice.

Jason Evans, board chairman of the Sitnasuak Native Corp., says crews on Monday hooked the hoses to a pipeline 550 yards from the tanker.

The city of 3,500 didn't get its last pre-winter barge fuel delivery because of a massive storm.

Without the Renda's delivery, Nome would run out of fuel long before the next barge delivery is possible.

Veteran Spanish politician Fraga dies at age 89 (AP)

MADRID ? Manuel Fraga Iribarne, a blunt-talking politician who founded Spain's ruling conservative party and ignited divisive reactions as the last surviving minister from Gen. Francisco Franco's right-wing regime, has died. He was 89.

Spanish news agency Europa Press said Fraga died late Sunday of heart failure at his Madrid home, citing a family member.

In a career spanning 60 years, Fraga served as Franco's information and tourism minister and as Spain's interior minister after the dictator died in 1975. But the job he coveted most ? being Spain's prime minister ? always eluded him.

Still, his influence on the country remained lasting.

Most Franco ministers quickly faded into obscurity after democracy was restored in 1978, but Fraga soldiered on. He helped write the country's post-Franco, democratic Constitution that was passed in 1978.

Although he repeatedly failed to be elected prime minister, he nudged Franco loyalists toward the political center, founded what is now the Popular Party and groomed Jose Maria Aznar to replace him as leader of the Spanish right in 1989.

In the post-Franco years, he ran his native Galicia region with a tight grip for 15 years and then settled into a seat in the Spanish Senate.

To the Spanish left, Fraga was a reviled and outspoken reminder of a right-wing regime that kept Spain isolated from Europe and the rest of the world for decades. In Galicia, critics say, he ruled despotically, manipulating a conservative political culture based on patronage to stay in power.

Defenders, however, note that Fraga promulgated a Franco-era law that did away with media censorship ? seen as a hint of change in the hardline regime. As tourism minister, Fraga worked to open up Spain to the outside world and bring in cash-laden visitors. A famous tourism slogan ? "Spain is different" ? which morphed into a popular Spanish saying was coined under Fraga's watch.

He is also credited with transforming northwestern Galicia ? traditionally one of Spain's poorest, most backward regions ? by building modern roads, bridges and other infrastructure, much of it paid for with EU funds. He boosted tourism and promoted Galicia's separate language and culture during his reign as president there from 1990 to 2005.

In a 2001 press luncheon, Fraga offered no apologies for his part in Spain's four decades of dictatorship.

"One cannot choose the period of history in which one lives," Fraga said, before quickly changing the subject.

Fraga was born Nov. 23, 1922, in the northwestern town of Villalba. He married Carmen Estevez in 1948 and they had five children. She died in 1996.

After distinguishing himself in academics and earning a law degree, Fraga held several midlevel positions in the Franco regime until he was promoted to minister of information and tourism in 1962.

In September 2011, 60 years after beginning his career, Fraga announced his retirement from politics, saying he would not seek another term in the Senate.

Fraga was noted for his rapid-fire yet mumbling style of speech and an impetuous streak, exemplified when he once snipped the cord of telephone in his office when it would not stop ringing.

Contemporary Spanish history is full of images of Fraga as well as his famed one-liners.

As interior minister in the first post-Franco government, but prior to the restoration of democracy, Spanish media reported that Fraga blurted out "La calle es mia!" ? "The streets are mine!" ? as he put down street demonstrations by labor unions, communists and others. Fraga later denied having said this.

In 1966, Fraga engaged in a famous effort at damage control when four American hydrogen bombs fell on the southern Spanish village of Palomares after a mid-air collision between a B-52 bomber and a refueling plane.

None of them exploded, but radiation was strewn when the plutonium-containing detonators on two of the bombs exploded. These two and a third bomb that had also hit the ground were found within a day.

But the fourth bomb had fallen into the sea and eluded recovery for 75 days.

While crews were frantically searching for it, Fraga ? a portly man in baggy swim trunks ? joined U.S. Ambassador Angier Biddle Duke in taking a much-publicized swim off Palomares' beach to show it was safe to go into the water.

New facility for animals in Bucks

QUAKERTOWN, Pa. -

There's a new home for animals in Bucks County.

The Bucks County SPCA has opened a new facility in Quakertown, Richland Township.

The building has been in the works for five years, and was completely funded by donors.

The new building includes a barn and allows the organization to expand their capabilities to help animals, large and small.

There's also an education room for community classes.

This is the second facility in Bucks County for the SPCA.

Officials said it with ease the burden of their current shelter.??

"A second shelter gives us the space to be flexible when we have a large influx of animals all at once," said Anne Irwin.

The current shelter will remain open once the new facility is officially up and running.??? Animals will be able to make the move in February.
