Nanotechnology Extends the Life of Moore’s Law

“Daniel Edelstein of I.B.M. Research is leading a team’s work in the use of self-assembling nanotechnology.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. 4) Until now, as chips became smaller, they also became faster in about the same proportion. It’s still true for transistors, but it’s no longer true for the wires used to connect transistors — and that slows performance gains. Daniel Edelstein, a program manager and fellow at I.B.M. Research, says, “We’re running out of steam.”
Mr. Edelstein is leading a team of researchers from inside and outside I.B.M. in developing a new way to solve the problem: using “self assembling” nanotechnology to make better insulators, raising performance. In this case, self-assembly involves creating so-called airgaps, vacuums a few nanometers wide that keep the billions of tiny copper wires in a chip from touching one another, instead of putting down a layer of insulating material and trying to align it effectively at the nanoscale. It’s more efficient, and it means that I.B.M. won’t need to spend $50 million on photolithographic equipment.
. . . While the technique is not quite done being tested, John E. Kelly III, I.B.M.’s senior vice president for research, says that “there is no question in our minds this is going to work,” and that I.B.M. will move to it by 2009, first for an existing high-end processor or a next-generation chip, then across its fabs.
Mr. Kelly says Mr. Edelstein has a “unique” ability to solve problems and work across the company to commercialize new technologies. In the last decade, he has led two other important breakthroughs, most notably the use of copper for the wires inside chips, replacing aluminum.
Each time, Mr. Edelstein has done it by working with a small group of two or three scientists to explore out-of-the-mainstream approaches to problems. He also goes beyond research, getting to know the manufacturing team to help him understand what it takes to get a novel technique into I.B.M.’s existing manufacturing process.

Hoosiers Were Right to Be Behind the Times

I am a Hoosier by birth and upbringing, and I am not ashamed to admit it, in spite of the fact that “hoosier” is a pejorative in some circles.
Until recently, in Indiana we swam against the tide, in rejecting Daylight Savings Time. It never made sense to me that in order to take advantage of sunlight, the government needed to mandate that the clocks be changed twice a year.
Why couldn’t those who want to use the hours of sunlight differently, simply adjust their own schedules, for example, by getting up earlier or later?
Well the article quoted below, suggests that us Hoosiers may have been wiser than we knew.

(p. D1) For decades, conventional wisdom has held that daylight-saving time, which begins March 9, reduces energy use. But a unique situation in Indiana provides evidence challenging that view: Springing forward may actually waste energy.
Up until two years ago, only 15 of Indiana’s 92 counties set their clocks an hour ahead in the spring and an hour back in the fall. The rest stayed on standard time all year, in part because farmers resisted the prospect of having to work an extra hour in the morning dark. But many residents came to hate falling in and out of sync with businesses and residents in neighboring states and prevailed upon the Indiana Legislature to put the entire state on daylight-saving time beginning in the spring of 2006.
Indiana’s change of heart gave University of California-Santa Barbara economics professor Matthew Kotchen and Ph.D. student Laura Grant a unique way to see how the time shift affects energy use. Using more than seven million monthly meter readings from Duke Energy Corp., covering nearly all the households in southern Indiana for three years, they were able to compare energy consumption before and after counties began observing daylight-saving time. Readings from counties that had already adopted daylight-saving time provided a control group that helped them to adjust for changes in weather from one year to the next.
Their finding: Having the entire state switch to daylight-saving time each year, rather than stay on standard time, costs Indiana households an additional $8.6 million in electricity bills. They conclude that the reduced cost of lighting in afternoons during daylight-saving time is more than offset by the higher air-conditioning costs on hot afternoons and increased heating costs on cool mornings.
“I’ve never had a paper with such a clear and unambiguous finding as this,” says Mr. Kotchen, who presented the paper at a National Bureau of Economic Research conference this month.

Greenspan on Leapfrogging in India

(p. 316) India is fast becoming two entities: a rising kernal of world-class modernity within a historic culture that has been for the most part stagnating for generations.
This kernal of modernity appears to have largely leapfrogged the twentieth-century labor-intensive manuafacturing-for-export model embraced by China and the rest of East Asia.

Government Supported Biofuels Increase Global Warming

Source of graph: online version of the WSJ article quoted and cited below.

(p. A4) While the U.S. and others race to expand the use and production of biofuels, two new studies suggest these gasoline alternatives actually will increase carbon-dioxide levels.
A study published in the latest issue of Science finds that corn-based ethanol, a type of biofuel pushed heavily in the U.S., will nearly double the output of greenhouse-gas emissions instead of reducing them by about one-fifth by some estimates. A separate paper in Science concludes that clearing native habitats to grow crops for biofuel generally will lead to more carbon emissions.
The findings are the latest to take aim at biofuels, which have already been blamed for pushing up prices of corn and other food crops, as well as straining water supplies. The Energy Department expects U.S. ethanol production to reach about 7.5 billion gallons this year from 3.9 billion in 2005, encouraged by high prices and government support. The European Union has proposed that 10% of all fuel used in transportation should come from biofuels by 2020.
Some scientists have praised biofuels because growing biofuel feedstock would remove gases that trap the sun’s heat from the air, while gasoline and diesel fuel take carbon from the ground and put it in the air. However, some earlier studies didn’t account for one hard-to-measure factor: the decision by farmers world-wide to convert forest and grasslands to grow feedstock for the new biofuels.
. . .
[One] study’s funding came from the National Science Foundation and the University of Minnesota’s Initiative on Renewable Energy and the Environment, . . . The other paper relied on funding from various indirect sources, including the Hewlett Foundation and the Agriculture Department.

Federal Subsidies for “Those Who Choose to Live Far from a City”

Source of graphic: the online version of the Omaha World-Herald article quoted and cited below.

(p. 1A) WASHINGTON — Opponents of federal air travel subsidies make two points: that subsidized airports are relatively close to regular commercial air service and subsidized flights are used by only a few people a day.
Both are true in Nebraska.
For example, U.S. taxpayers spend nearly $1.4 million a year so that fewer than two dozen travelers a day, on average, can fly out of Grand Island rather than drive the 100 miles to Lincoln.
Taxpayers also chip in $748,635 annually to maintain two daily flights from Alliance to Denver, even though only about a half dozen people a day board the planes.
. . .
(p. 2A) Groups such as Taxpayers for Common Sense and Citizens Against Government Waste say that although the subsidies might have made sense 30 years ago, to prevent communities from losing air service overnight, people know what they’re getting into today if they choose to live far from a city with regular air service.
It’s a matter of prioritizing public spending, said Steve Ellis, vice president of Taxpayers for Common Sense.
“People have the right to food and clean water,” Ellis said. “We don’t need to make sure it’s a chicken in every pot and air service in every community.”

Global Warming Hits the Arctic (But Skips the Antarctic?)

A New York Times article spent nine paragraphs on the damage to the Arctic from global warming. At the top of the article is a substantial photo showing shrinking ice around Canada’s Northwest Passage.
Then at the end of the article, there is a tenth paragraph, consisting of the following single sentence:

(p. A6) Sea ice around Antarctica has seen unusual winter expansions recently, and this week is near a record high.

Global warming is an important issue. So in judging the truth and severity of global warming, why is the shrinking of ice in the arctic, worth so much more attention than the expanding of ice in the antarctic?
(In fairness to the NYT, given the overwhelming politically correct pressure to be onboard the global warming bandwagon, especially among NYT readers, one might argue that what made the article notable was not that it lacked objective balance, but that the NYT had the courage to include the final sentence at all.)

Seniors Want Independence and to Live in Familiar Surroundings

“Climbing stairs is a challenge for George Allen.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. A1) WASHINGTON — On a bluff overlooking the Potomac River, George and Anne Allen, both 82, struggle to remain in their beloved three-story house and neighborhood, despite the frailty, danger and isolation of old age.
Mr. Allen has been hobbled since he fractured his spine in a fall down the stairs, and he expects to lose his driver’s license when it comes up for renewal. Mrs. Allen recently broke four ribs getting out of bed. Neither can climb a ladder to change a light bulb or crouch under the kitchen sink to fix a leak. Stores and public transportation are an uncomfortable hike.
So the Allens have banded together with their neighbors, who are equally determined to avoid being forced from their homes by dependence. Along with more than 100 communities nationwide — a dozen of them planned here in Washington and its suburbs — their group is part of a movement to make neighborhoods comfortable places to grow old, both for elderly men and women in need of help and for baby boomers anticipating the future.
“We are totally dependent on ourselves,” Mr. Allen said. “But I want to live in a mixed community, not just with the elderly. And as long as we can do it here, that’s what we want.”
Their group has registered as a nonprofit corporation, is setting membership dues, and is lining up providers of transportation, home repair, companionship, security and other services to meet their needs at home for as long as possible.
Urban planners and senior housing experts say this movement, organized by residents rather than government agencies or social service providers, could make “aging in place” safe and affordable for a majority of elderly people. Almost 9 in 10 Americans over the age of 60, according to AARP polls, share the Allens’ wish to live out their lives in familiar surroundings.
. . .
(p. A18) The first village in the Washington area is expected to be on Capitol Hill. When it opens for business on Oct. 1, annual memberships will be $750 for a couple and $500 for an individual.
Among those eager to join are Marie Spiro, 74, and Georgine Reed, 78, who share a rambling house that they insist they will only leave “feet first.” Between them, Ms. Spiro, an emeritus professor of art history and archaeology, and Ms. Reed, a retired designer of museum exhibits, have already endured three knee replacements and an array of other ailments.
Ms. Spiro describes huffing and puffing while grocery shopping; Ms. Reed is increasingly reluctant to visit friends across town. Both women, who are childless, would already welcome help with meals, transportation and paperwork. If they need home care, Capitol Hill Village will be able to organize that.
“I’ve never had to rely on other people, and I never wanted to,” Ms. Spiro said. “But I’d rather pay a fee than have to ask favors.”

Wal-Mart Designs Health Care Around the Needs of Consumers

“Alicia Ledlie, senior director of health business development for Wal-Mart, said walk-in medical clinics would look like the mockup behind her, in a warehouse in Bentonville, Ark.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. C4) Moving to upgrade its walk-in medical clinic business, Wal-Mart is set to announce on Thursday plans for several hundred new clinics at its stores, using a standardized format and jointly branded with hospitals and medical groups.
. . .
Walk-in medical clinics are a growing industry, with numerous competitors that include big-box retailers, drugstores and even grocery chains around the country. Industry executives say 1,500 to 1,800 clinics will be open by the end of the year.
Propelled by the drugstore chains CVS and Walgreens, by far the biggest sponsors of the clinics to date, more than 700 clinics have opened in the last 15 months. But the business model is unproven so far.
Few, if any, clinics are profitable, according to industry analysts, and only a handful have broken even on daily operations. Most have been open a year or less, and executives say it takes up to three years for a clinic to become profitable enough to recover start-up costs.
Medical societies are inclined to be skeptical of the clinics. The American Academy of Pediatrics opposes them, saying they add to fragmentation in the health care system.
Dr. Edward Zissman, a pediatrician in central Florida, said he had qualms about hospitals that hook up with the clinics. “Putting their name on a product that I don’t think has the highest quality,” he said, “is going to cost them dearly with physicians.”
The American Academy of Family Physicians and the American Medical Association have set forth principles for clinics to observe, including sending patients’ medical record to their doctors and finding doctors for patients who do not already have them. Most states require varying degrees of physician supervision of the clinic nurses. Clinic operators say they are complying.
Many patients have said they like the convenience of the walk-in clinics’ weekend and evening hours, the short waiting times to see a nurse practitioner, and the posted price lists for a limited menu of care like tests and prescriptions for sore throats and ear infections and seasonal flu shots.
. . .
“The clinics are the latest big example of how you could think about consumers and what their needs are, rather than a health care system exclusively designed around the needs of providers,” said Margaret Laws, director of an innovations program at the California Health Care Foundation, an independent group that finances health policy research.

Hitler’s Critique of American Materialism

Here are some musings by Hitler, in which he compares Germany under Hitler’s National Socialism, with America. The musings are dated August 1, 1942, and are quoted in the article cited below:

(p. 3) I grant you that our standard of life is lower. But the German Reich has 270 opera houses – a standard of cultural existence of which they over there have no conception. They have clothes, food, cars and a badly constructed house – but with a refrigerator! This sort of thing does not impress us.

“Isn’t This a Teeny-Weeny Bit of Socialism?”

(p. 12) FROM the very beginning of the nation’s modern social welfare system — even before Michael Moore began to explore the issue — there was a tension in it: What should the government be expected to provide? What should be left to the individual? How much government is too much?
The questions were asked even in 1935, not exactly a time to instill confidence in the resilient power of private markets. Senator Thomas Pryor Gore, Democrat of Oklahoma, put it bluntly when Frances Perkins, the secretary of labor, testified on Capitol Hill that year about President Franklin D. Roosevelt’s plan for a new program called Social Security.
”Isn’t this socialism?” Senator Gore demanded. When Ms. Perkins denied it, he asked again: ”Isn’t this a teeny-weeny bit of socialism?” In recent days, on Capitol Hill and on the campaign trail, a new version of that debate has been flaring, this time around an issue that the New Dealers decided (perhaps wisely) to put off for a later date: health care.

Active Volcano in Antarctica: Another Cause for Melting Ice

Source of graphic: online version of the NYT article quoted and cited below.

(p. A8) Here is another factor that might be contributing to the thinning of some of the Antarctica’s glaciers: volcanoes.
In an article published Sunday on the Web site of the journal Nature Geoscience, Hugh F. J. Corr and David G. Vaughan of the British Antarctic Survey report the identification of a layer of volcanic ash and glass shards frozen within an ice sheet in western Antarctica.
For Antarctica, “This is the first time we have seen a volcano beneath the ice sheet punch a hole through the ice sheet,” Dr. Vaughan said.
Heat from a volcano could still be melting ice and contributing to the thinning and speeding up of the Pine Island Glacier, which passes nearby, but Dr. Vaughan doubted that it could be affecting other glaciers in West Antarctica, which have also thinned in recent years. Most glaciologists, including Dr. Vaughan, say that warmer ocean water is the primary cause.
