The CBC's reposting of this Canadian Press report on the changing political balance deserves to be reposted. The past decade's ascent of the NDP from third-place national opposition party (fourth if you include the regionally-concentrated Bloc Québécois) to Official Opposition making inroads in Conservative areas is a fascinating story.

(The NDP's ascent has strongly negative implications for the Liberal Party, especially if the apparent shift of voters from the Liberal Party to the NDP is sustained.)

The Canadian Press Harris Decima survey indicates that the NDP have 34 per cent of popular support, compared to 30 per cent for the Conservatives.

With a margin of error of 2.2 percentage points, support for the two parties could be equally split.

Still, the poll indicates that the New Democrats have become competitive in traditional Tory areas.

Among rural Canadians, the poll suggests the New Democrats have 31 per cent support, compared to 35 per cent for the Tories.

The NDP appear to have the support of 36 per cent of urban and suburban men, a number that has risen steadily since February.

Meanwhile, the Conservatives are seeing their support in that demographic appear to hover around 29 per cent, down from close to 40 per cent four months ago.

As well, the New Democrats appear to have supplanted the Liberals as the natural party among women, said Allan Gregg, chairman of Harris Decima.

"Remember this is a party that a decade ago, half the electorate said they would "never" vote for," he said.

Ella Davies' BBC Nature report about humpback whale sociability makes me think.

A BBC/National Geographic film crew have recorded rare footage of humpback whales intervening in a killer whale hunt.

[. . .]

"To be honest we weren't expecting to see anything - it was our very first day out on the boat," said Victoria Bromley, a researcher with the crew that witnessed the scene.

Working from a whale-watching boat from Monterey Bay Whale Watch, the team set up to film in an area known for sightings of gray whales.

Every year female gray whales travel north from the birthing waters off the coast of Mexico to the nutrient rich waters of the Bering Sea with their calves.

Along the route, they are targeted by orcas, which co-ordinate their attacks - aiming to separate the defenceless young from their mothers.

To minimise their risk from the predators, gray whales swim in relatively shallow water but at Monterey Bay the whales must swim over the Monterey Canyon that in places can reach two miles deep.

The film crew arrived at the scene of the hunt following a tip off call from a sister boat.

Using a camera mounted on the boat, Ms Bromley told BBC Nature: "we saw a lot of grey shapes in the water and quickly realised they were humpbacks."

According to the crew the additional whales were not just observers of the hunt but were actively involved.

The humpbacks at Monterey Bay were trumpeting, diving and slapping their pectoral fins against the water.

"It didn't seem at all like they were confused… they were definitely there with a purpose," said Ms Bromley.

Shortly after the crew arrived the orca successfully caught their prey. The mother whale fled the scene but the humpbacks remained.

"I have never seen anything like this before," said marine biologist Alisa Schulman-Janiger who accompanied the filmmakers.

Mrs Schulman-Janiger has studied California killer whales since 1984 and is currently the director of the American Cetacean Society/Los Angeles Chapter's Gray Whale Census and Behavior Project.

After the attack, two humpback whales moved into the area where the calf was last seen alive. They continued to make trumpeting calls, rolled in the water and slashed their tails aggressively at killer whales that came near.

Michael Balter's ScienceNOW is another interesting data point.

Three years ago, a stone-throwing chimpanzee named Santino jolted the research community by providing some of the strongest evidence yet that nonhumans could plan ahead. Santino, a resident of the Furuvik Zoo in Gävle, Sweden, calmly gathered stones in the mornings and put them into neat piles, apparently saving them to hurl at visitors when the zoo opened as part of angry and aggressive “dominance displays.”

But some researchers were skeptical that Santino really was planning for a future emotional outburst. Perhaps he was just repeating previously learned responses to the zoo visitors, via a cognitively simpler process called associative learning. And it is normal behavior for dominant male chimps to throw things at visitors, such as sticks, branches, rocks, and even feces. Now Santino is back in the scientific literature, the subject of new claims that he has begun to conceal the stones so he can get a closer aim at his targets—further evidence that he is thinking ahead like humans do.

The debate over Santino is part of a larger controversy over whether some humanlike animal behaviors might have simpler explanations. For example, Sara Shettleworth, a psychologist at the University of Toronto in Canada, argued in a widely cited 2010 article entitled, “Clever animals and killjoy explanations in comparative psychology,” that the zookeepers and researchers who observed Santino’s stone-throwing over the course of a decade had not seen him gathering the stones, and thus could not know why he originally starting doing so. Santino, Shettleworth and some others argued, might have had some other reasons for caching the stones, and the stone throwing might have been an afterthought.

In the new study, published online today in PLoS ONE, primatologist Mathias Osvath of Lund University in Sweden—author of the earlier Santino paper—teams up with Lund University primatologist Elin Karvonen to report new observations of Santino’s behavior during 2010. Santino’s first attempts to throw stones during 2010 came during the May preseason. As a zoo guide led visitors toward Santino’s island compound, the chimpanzee began to engage in a typical dominance display: screeching, standing on two feet, and carrying a stone in his hand. The guide and the visitors retreated before Santino began hurling the stones, and then advanced again for a total of three approaches. When the people returned about 3 hours later, Santino advanced toward them, holding two stones, but he did not act aggressively, even picking up an apple from the water surrounding the island and nonchalantly munching on it. But when Santino got within close range, he suddenly threw one of the stones. (It didn’t hit anyone.)

The next day, Santino again threatened visitors with stones, but the group again backed away to avoid being hit. Santino was then observed pulling a heap of hay from inside his enclosure and placing it on the island close to where the visitors approached. He put several stones under the hay and waited until the group returned about an hour later. Then, without performing a dominance display, Santino pulled a stone from under the hay and threw it. Later, he pulled a stone that he had apparently hidden behind a log and tried to hit the visitors with that, as well.

Over the course of the summer, Osvath and Karvonen observed repeated episodes of this behavior, and also recovered stones that Santino had hidden under hay or logs, racking up 114 days of observation. They recovered a total of 35 projectiles that Santino had apparently concealed: 15 under hay heaps, 18 behind logs, and two behind a rock structure on the island. The researchers conclude that Santino deliberately engaged in deceptive concealment of the stones, and that this was a new, innovative behavior on his part: Before 2010, Santino had never put stones under hay piles or behind logs.

Geocurrents' Asya Pereltsvaig reports on news that Japan is apparently altering its policy on the Kurils, hoping that a partition of the Kurils between Japan and Russia on north-south lines, giving Japan the islands nearest Hokkaido--Shikotan and the Habomai islet groups--and letting Russia keep the northern islands. This is an attempt at compromise, true, but I don't think it'll work out for the reasons Pereltsvaig highlights. Me, as I noted in 2010, Japan is the only defeated Second World War country still claiming territory lost in 1945; there's something off about that. IMHO.

The idea to negotiate the return of Shikotan and the Habomai group as a first step in the resolution of this long-standing diplomatic impasse belongs to the then Prime Minister Yoshiro Mori, who proposed it to Russian President Vladimir Putin in March 2001. However, negotiating the return of two rather than all four islands at once met with resistance in Japan, because of fears that such an arrangement would result in Moscow retaining control of Etorofu and Kunashiri indefinitely. Such concerns prompted Mori’s successor Prime Minister Junichiro Koizumi to seek a comprehensive resolution to the dispute before the two sides conclude a peace treaty, but Putin ultimately dismissed the suggestion. The revival of the idea to negotiate over just two islands coincides with Putin’s return to the presidency yesterday, as the president-elect expressed a certain degree of willingness to resolve the issue in an interview with foreign media outlets in March of this year. However, other Russian media outlets, such as Fontanka.ru, claim that “no Russian president will ever relinquish the Kurils to Japan” and cite sources in the Kremlin as saying that “Japan missed its historical chance to solve this territorial problem already in 1996 when President Boris Yeltsin met with the Japanese Prime Minister Ryutaro Hashimoto in Krasnoyarsk”.

Tumblr's lostmuskrat linked to Winslow Wheeler's Foreign Policy article about the existential failings of the F-35. The cause of significant pricetag-related issues in Canada, it's all the more problematic for the country that's actually building it.

How bad is it? A review of the F-35's cost, schedule, and performance -- three essential measures of any Pentagon program -- shows the problems are fundamental and still growing.

First, with regard to cost -- a particularly important factor in what politicians keep saying is an austere defense budget environment -- the F-35 is simply unaffordable. Although the plane was originally billed as a low-cost solution, major cost increases have plagued the program throughout the last decade. Last year, Pentagon leadership told Congress the acquisition price had increased another 16 percent, from $328.3 billion to $379.4 billion for the 2,457 aircraft to be bought. Not to worry, however -- they pledged to finally reverse the growth.

The result? This February, the price increased another 4 percent to $395.7 billion and then even further in April. Don't expect the cost overruns to end there: The test program is only 20 percent complete, the Government Accountability Office has reported, and the toughest tests are yet to come. Overall, the program's cost has grown 75 percent from its original 2001 estimate of $226.5 billion -- and that was for a larger buy of 2,866 aircraft.

[. . .]

A final note on expense: The F-35 will actually cost multiples of the $395.7 billion cited above. That is the current estimate only to acquire it, not the full life-cycle cost to operate it. The current appraisal for operations and support is $1.1 trillion -- making for a grand total of $1.5 trillion, or more than the annual GDP of Spain. And that estimate is wildly optimistic: It assumes the F-35 will only be 42 percent more expensive to operate than an F-16, but the F-35 is much more complex. The only other "fifth generation" aircraft, the F-22 from the same manufacturer, is in some respects less complex than the F-35, but in 2010, it cost 300 percent more to operate per hour than the F-16. To be very conservative, expect the F-35 to be twice the operating and support cost of the F-16.

[. . .]

The F-35 isn't only expensive -- it's way behind schedule. The first plan was to have an initial batch of F-35s available for combat in 2010. Then first deployment was to be 2012. More recently, the military services have said the deployment date is "to be determined." A new target date of 2019 has been informally suggested in testimony -- almost 10 years late.

If the F-35's performance were spectacular, it might be worth the cost and wait. But it is not. Even if the aircraft lived up to its original specifications -- and it will not -- it would be a huge disappointment. The reason it is such a mediocrity also explains why it is unaffordable and, for years to come, unobtainable.

[. . .]

The design was born in the late 1980s in the Defense Advanced Research Projects Agency (DARPA), the Pentagon agency that has earned an undeserved reputation for astute innovation. It emerged as a proposal for a very short takeoff and vertical-landing aircraft (known as "STOVL") that would also be supersonic. This required an airframe design that -- simultaneously -- wanted to be short, even stumpy, and single-engine (STOVL), and also sleek, long, and with lots of excess power, usually with twin engines.

President Bill Clinton's Pentagon bogged down the already compromised design concept further by adding the requirement that it should be a multirole aircraft -- both an air-to-air fighter and a bomber. This required more difficult tradeoffs between agility and low weight, and the characteristics of an airframe optimized to carry heavy loads. Clinton-era officials also layered on "stealth," imposing additional aerodynamic shape requirements and maintenance-intensive skin coatings to reduce radar reflections. They also added two separate weapons bays, which increase permanent weight and drag, to hide onboard missiles and bombs from radars. On top of all that, they made it multiservice, requiring still more tradeoffs to accommodate more differing, but exacting, needs of the Air Force, Marine Corps, and Navy.
