Mice See New Hue With Added Gene

Thursday, April 12th, 2007

Providing a kaleidoscopic upgrade to creatures that are largely colorblind, scientists have endowed mice with a human gene that allows the rodents to see the world in full Technicolor splendor.

The advance, which relied on imaginative tests to confirm that the mice can perceive all the hues that people see, helps resolve a long-standing debate about how color vision arose in human ancestors tens of millions of years ago. That seminal event brought a host of practical advantages, such as the ability to spot ripe fruit, and unveiled new aesthetic pleasures — autumn foliage, magenta sunsets and the blush of a potential mate, among them.

The work also points to the possibility of curing some of the millions of colorblind Americans — and even enhancing the vision of healthy people, allowing them to experience a richer palette than is possible with standard-issue eyes.

“It opens up huge doors to understanding how color vision evolved and where it can go,” said Brian C. Verrelli, an evolutionary geneticist who studies color vision at Arizona State University and was not involved in the work, published today in the journal Science.

Mice, like most mammals, have limited color perception, equivalent to that of people with red-green color blindness. Their eyes have two kinds of color detectors, or “cone” cells, each sensitive to a different part of the spectrum.

Unable to differentiate between reds and greens, they see the world as a blend of blues and yellows, with gray overlays added by black-and-white-registering “rod” cells.

By contrast, most people — along with Old World primates and South and Central American female monkeys — have three kinds of cones. That gives birth to the vibrant world of reds and a vast repertoire of related colors.

Climate Change: Natural Wonders Of The World Face Destruction

Thursday, April 12th, 2007

Science Daily From the Amazon to the Himalayas, ten of the world’s greatest natural wonders face destruction if the climate continues to warm at the current rate, warns WWF.

Released ahead of the International Panel on Climate Change’s (IPCC’s) Second Working Group Report, a WWF briefing — Saving the world’s natural wonders from climate change — reports on how the devastating impacts of global warming are damaging some of the world’s greatest natural wonders.

They include the: Amazon; Great Barrier Reef and other coral reefs; Chihuahua Desert in Mexico and the US; hawksbill turtles in the Caribbean; Valdivian temperate rainforests in Chile; tigers and people in the Indian Sundarbans; Upper Yangtze River in China; wild salmon in the Bering Sea; melting glaciers in the Himalayas; and East African coastal forests.

Novelist Kurt Vonnegut dies at age 84

Wednesday, April 11th, 2007

– A free thinker who expanded many of our minds. May we be blessed with more like him.

– In 2005, he characterized the Bush administration as, “upper crust C-students who know no history or geography“.   That made me smile. 

———————————

NEW YORK — Kurt Vonnegut, the satirical novelist who captured the absurdity of war and questioned the advances of science in darkly humorous works such as “Slaughterhouse-Five” and “Cat’s Cradle,” died Wednesday. He was 84.

Vonnegut, who often marveled that he had lived so long despite his lifelong smoking habit, had suffered brain injuries after a fall at his Manhattan home weeks ago, said his wife, photographer Jill Krementz.

The author of at least 19 novels, many of them best-sellers, as well as dozens of short stories, essays and plays, Vonnegut relished the role of a social critic. He lectured regularly, exhorting audiences to think for themselves and delighting in barbed commentary against the institutions he felt were dehumanizing people.

“I will say anything to be funny, often in the most horrible situations,” Vonnegut, whose watery, heavy-lidded eyes and unruly hair made him seem to be in existential pain, once told a gathering of psychiatrists.

A self-described religious skeptic and freethinking humanist, Vonnegut used protagonists such as Billy Pilgrim and Eliot Rosewater as transparent vehicles for his points of view. He also filled his novels with satirical commentary and even drawings that were only loosely connected to the plot. In “Slaughterhouse-Five,” he drew a headstone with the epitaph: “Everything was beautiful, and nothing hurt.”

070411 – Wednesday – Surgery day

Wednesday, April 11th, 2007

I’m departing in the next few minutes to have an athroscopy proceedure done on my right knee. I damaged it in November in New Zealand. I’ll be back in a few hours and hobbling about for the next week or so. I had this done on the left knee about ten years ago and it went well.

Wish me luck, dear readers.

Cheers.

Later.   it all seemed to go well.   I’m sitting here now in a pain reliever induced fog (smiling a lot) and goofing off.   Won’t be much serious intellectual stuff possible until at least tomorrow.   Until then, I’m in Dilbert-land.

Cheers!

UK schools are dropping teaching the Holocaust

Tuesday, April 10th, 2007

– This is utterly amazing. If the holocaust happened, and I believe it did, then why should anyone fear to teach it? But, in the UK, teachers are choosing to not teach about it to avoid offending Muslim students who’ve been taught otherwise. Amazing.

Coral Reef Collapse Spells Danger For Millions

Tuesday, April 10th, 2007

Science Daily Island communities that depend on coral reef fisheries could face a hungry future, according to new research from the University of East Anglia, the Centre for Environment, Fisheries & Aquaculture Science (Cefas), and Simon Fraser University in Canada, published in Current Biology.

The report on island coral reef fisheries reveals that over half (55%) of the 49 island countries reviewed were being exploited unsustainably. Fish landings are currently 64% higher than can be sustained. In order to support this level of exploitation, an additional 75,000 km2 of coral reef would be needed – an area 3.7 times greater than Australia’s Great Barrier Reef. These figures will nearly triple by 2050, given current human population growth projections.

Katie Newton, of the University of East Anglia’s School of Biological Sciences, undertook a survey of the landing catches of 49 island nations across the Pacific, Indian and Atlantic Oceans.

“Millions of people are dependent on coral reef fisheries. We are facing a global crisis among communities which have limited alternative livelihoods or major food sources,” she said.

070410 – Tuesday – more Kim Stanley Robinson

Tuesday, April 10th, 2007

I know I wrote just the other day about the fact that I’m reading a book, Sixty Days and Counting, by Kim Stanley Robinson. It’s a great book and an excellent finish to his trilogy on the global climate change crises.

When I wrote last time, I quoted a section from his book and I said that I hoped he’d forgive me for the transgression. Well, I’m afraid his book is just too good and I’m going to do it again. I expect his book company lawyers will be knocking on my door any day now.

The following is a discussion, from the book, between the newly elected President’s science advisory staff, led by Charlie, people from the Intergovernmental Panel of Climate Change and people from the World Bank. They are not seeing eye to eye about the world’s problems and it makes for interesting reading. When I was reading this, I just wanted to stand up and shout, “Yes!”

Enjoy:

——————————————

This meeting with the Intergovernmental Panel on Climate Change, a UN organization, might be a good venue for exerting some pressure. The IPCC had spent many years advocating action on the climate front, and all that while they had been flatly ignored by the World Bank. If there was now a face-off, a great reckoning in a little room, then it could get interesting.

But the meeting, held across the street in the World Bank headquarters, was a disappointment. These two groups came from such different world-views that it was only an illusion they were speaking the same language; for the most part they used different vocabularies, and when by chance they used the same words, they meant different things by them. They were aware at some level of this underlying conflict, but could not address it; and so everyone was tense, with old grievances unsayable and yet fully present.

The World Bank guys said something about nothing getting cheaper than oil for the next fifty years, ignoring what the IPCC guys had just finished saying about the devastating effects fifty more years of oil burning would have. They had not heard that, apparently. They defended having invested 94 percent of the World Bank’s energy investments in oil exploration as necessary, given the world’s dependence on oil – apparently unaware of the circular aspect of their argument. And, being economists, they were still exteriorizing costs without even noticing it or acknowledging such exteriorization had been conclusively demonstrated to falsify accounts of profit and loss. It was as if the world was not real – as if the physical world, reported on by scientists and witnessed by all, could be ignored, and because their entirely fictitious numbers therefore added up, no one could complain.

Charlie gritted his teeth as he listened and took notes. This was science verses capitalism, yet again. The IPCC guys spoke for science and said the obvious things, pointing out the physical constraints of the planet, the carbon load now in the atmosphere altering everything, and the resultant need for heavy investment in clean replacement technologies by all concerned, including the World Bank, as one of the great drivers of globalization. But they had said it before to no avail, and so it was happening again. The World Bank guys talked about rates of return and the burden on investors, and the unacceptable doubling of the price of the kilowatt hour. Everyone there had said all of this before, with the same lack of communication and absence of concrete results.

Charlie saw that the meeting was useless. … The bank guy was going on about differential costs, “and that’s why it’s going to be oil for the next twenty, thirty, maybe even fifty years,” he concluded. “None of the alternatives are competitive.”

Charlie’s pencil tip snapped. “Competitive for what?” he demanded.

He had not spoken until that point, and now the edge in his voice stopped the discussion. Everyone was staring at him. He stared back at the World Bank guys.

“Damage from carbon dioxide emission costs about $35 a ton, but in your model no one pays for it. The carbon that British Petroleum burns per year, by sale and operation, runs up a damage bill of fifty billion dollars. BP reported a profit of twenty billion, so actually it’s thirty billion in the red, every year. Shell reported a profit of twenty-three billion, but if you add the damage cost it would be eight billion in the red. These companies should be bankrupt. You support their exteriorizing of costs, so your accounting is bullshit. You’re helping bring on the biggest catastrophe in human history. If the oil companies burn the five hundred gigatons of carbon that you are describing as inevitable because of your financial shell games, then two-thirds of the species on the planet will be endangered, including humans. But you keep talking about fiscal discipline and competitive edges in profit differentials. It’s the stupidest head-in-the-sand response possible.”

The World Bank guys flinched at this. “Well,” one of them said, “we don’t see it that way.”

Charlie said, “That’s the trouble. You see it the way the banking industry sees it, and they make money by manipulating money irrespective of effects in the real world. You’ve spent a trillion dollars of American taxpayers’ money over the lifetime of the bank, and there’s nothing to show for it. You go into poor countries and force them to sell their assets to foreign investors and to switch from subsistence agriculture to cash crops, then when the prices of these crops collapse you call this nicely competitive on the world market. The local populations starve and you then insist on austerity measures even though your actions have shattered their economy. You order them to cut their social services so they can pay off their debts to you and your financial community investors, and you devalue their real assets and then buy them on the cheap and sell them elsewhere for more. The assets of that country have been strip-mined and now belong to international finance. That’s your idea of development. You were intended to be the Marshall Plan, and you’ve been the United Fruit Company.”

One of the World Bank guys muttered, “But tell us what you really think,” while putting his papers in his briefcase. His companions snickered, and this gave him courage to continue: “I’m not gonna stay and listen to this,” he said.

“That’s fine,” Charlie said. “You can leave now and get a head start on looking for a new job.”

The man blinked hostilely at him. But he did not otherwise move.

Charlie stared at him for a while, working to collect himself. He lowered his voice and spoke as calmly as he could manage. He outlined the basics of the new mission architecture, including the role that the World Bank was now to play; but he couldn’t handle going into detail with people who were now furious at him, and in truth had never been listening. … So Charlie wrapped it up, then gave them a few copies of the mission architecture outline, thick books that had been bound just that week. “Your part of the plan is here in concept. Take it back and talk it over with your people, and come to us with your plan to enact it. We look forward to hearing your ideas. I’ve got you scheduled for a meeting on the sixth of next month, and I’ll expect your report then.” Although, since we will be decapitating your organization, it won’t be you guys doing the reporting, he didn’t add.

And he gathered his papers and left the room.

To Fortify China, Soybean Harvest Grows in Brazil

Tuesday, April 10th, 2007

– I’ve been pointing out for some time that as China’s ability to feed itself begins to falter due to increasing population, eating higher on the food chain as a result of growing affluence, desertification and diminishing water supplies, they will inevitably draw from their huge balance of trade surplus funds and simply go out into the world market and buy what they need with impunity. It makes sense – who wouldn’t?

– But, while it makes sense for them, it is inevitably going to wreak havoc with the affordability and availability of food supplies for the rest of the world with a special emphasis on the world’s poorer nations. And this, in turn, will lead to social unrest and increasing political fundamentalism as no one likes to starve quietly.

——————————-

RONDONÓPOLIS, Brazil — For more than 2,000 years, the Chinese have turned soybeans into tofu, a staple of the country’s diet.

But as its economy grows, so does China’s appetite for pork, poultry and beef, which require higher volumes of soybeans as animal feed. Plagued by scarce water supplies, China is turning to a new trading partner 15,000 miles away — Brazil — to supply more protein-packed beans essential to a richer diet.

China’s global scramble for natural resources is leading to a transformation of agricultural trading around the world. In China, vanishing cropland and diminishing water supplies are hampering the country’s ability to feed itself, and the increasing use of farmland in the United States to produce biofuels is pushing China to seek more of its staples from South America, where land is still cheap and plentiful.

“China is out there beating the bushes,” said Robert L. Thompson, a professor at the University of Illinois who is a former director of agricultural and rural development at the World Bank. The goal, he said, is “to ensure they have access to long-term contracts for minerals and energy and food.”

070410 – Tuesday – A great example of local activism

Tuesday, April 10th, 2007

I’ve added a new website, G.R.I.T., to the list of websites that I like and support on this Blog. You will find the list of these websites along the right side of your browser screen if you scroll down.

G.R.I.T. stands for Governmental Responsibility, Integrity and Truth. It is a website focused on issues having to do with local government here in the Western Washington Sky Valley area.

For those of you who follow this Blog from a distance, this may seem to be of remote interest but I encourage you to have a look. Local governments in any and all parts of the world could be much improved if their local citizens focused on and tracked the behavior, decisions and rational of their elected representatives with the same fervor and passion that these folks do. I guarantee you that very little happens in the town of Sultan, Washington, that is not closely examined, discussed and debated thanks to these people and the entire area is much the better for it.

U.S. Southwest Drought Could Be Start of New Dust Bowl

Monday, April 9th, 2007

The unprecedented drought that has gripped the southwestern United States isn’t almost over, researchers say, it may have only just begun.

That’s the consensus of all but 1 of the 19 climate models used as the basis for this week’s upcoming report from the Intergovernmental Panel on Climate Change (IPCC), according to a new analysis.

Richard Seager, a senior research scientist with the Lamont Doherty Earth Observatory, and co-authors report their findings today in the online advance version of the journal Science.

Based on the climate models, the U.S. Southwest and parts of northern Mexico could become as arid as the North American Dust Bowl conditions of the 1930s, the study authors report.

“If these models are correct, the levels of aridity of the recent multiyear drought [will] become the new climatology of the American Southwest,” the team writes.
