McCain on Iran
John McCain made a major speech last week asking the world's leading corporations to stop investing in Iran. That will be followed by an even bigger speech asking them to stop investing in Barack Obama...

Obama: The Fights: Let's Face It, He Wins 'Em
“…during a Senate vote Wednesday, Obama dragged Lieberman by the hand to a far corner of the Senate chamber and engaged in what appeared to reporters in the gallery as an intense, three-minute conversation.
While it was unclear what the two were discussing, the body language suggested that Obama was trying to convince Lieberman of something and his stance appeared slightly intimidating.
Using forceful, but not angry, hand gestures, Obama literally backed up Lieberman against the wall, leaned in very close at times, and appeared to be trying to dominate the conversation, as the two talked over each other in a few instances..."
On wing-nut blab jockey Mike Gallagher’s radio show today, former House Majority Leader Tom DeLay (R-TX), who is currently facing charges of money laundering and conspiracy to launder money, launched a fringe attack on Sen. Barack Obama (D-IL) by claiming that he is a Marxist. “I have said publicly, and I will again, that unless he proves me wrong, he is a Marxist,” DeLay declared.
Gallagher couldn’t agree more, saying “That’s what he is”…
From a Commenter named “Hunter” on Daily Kos:
“Unless he proves me wrong, Tom Delay lures children into his van with candy, gasses them to death with bug spray, and uses their powdered bones as an aphrodisiac when making love to all the animals at the San Antonio Sea World.”
A Few Obama-Positive Quotes
“I face this challenge...with limitless faith in the capacity of the American people. Because if we are willing to work for it, and fight for it, and believe in it, then I am absolutely certain that generations from now, we will be able to look back and tell our children that this was the moment when we began to provide care for the sick and good jobs to the jobless; this was the moment when we ended a war and secured our nation and restored our image as the last, best hope on Earth. This was the moment - this was time - when we came together to remake this great nation so that it may always reflect our very best selves and our highest ideals.”[Senator Barack Obama]
"[Dr. King’s] appeal was rooted in the larger context of nonviolence. His stated purpose was always to redeem the soul of America… To see Dr. King and his colleagues as anything less than modern founders of democracy - even as racial healers and reconcilers - is to diminish them under the spell of myth. Dr. King said the movement would liberate not only segregated black people but also the white South. Surely this is true."
[Taylor Branch, “The Last Wish of Martin Luther King”]
"Americans are going to have to choose between the Obama and McCain.
It's a choice between the Hillary-defeater or the Wal-Mart greeter."

Gold Nanoparticles Go Couture
Marino wool is about to go high-fashion.
By adding nanoparticles made of pure gold and silver to fine Marino wool, researchers in New Zealand have created a rainbow of unexpected colors intended for high-end, couture fashion designers.
They unveiled the first scarf dyed with gold nanoparticles last week at the Nano Science and Technology Institute convention in Boston.
"We want to create a fashion icon, like Louis Vutton or Gucci, where the logo will speak for itself," said James Johnston, the lead researcher from Victoria University in New Zealand.
"You could say that you are clothed in pure gold or silver," said Johnston.
The dyed wool is not gold or silver in color, however. When dyed with gold nanoparticles, wool, or just about any other fabric for that matter, ranges from purple to yellow and everything in between.
Silver nanoparticles create bright yellows, greens and oranges.
The researchers can even combine and mix colors to create new ones. Varying the amount of gold or silver nanoparticles determines the shade's intensity.
The color of the wool depends on the type of precious metal used, the size of the nanoparticles, and in some cases, their shape.
Spherical gold nanoparticles about 10 nanometers across create a red wine color. As their size increases to 100 nanometers, the color turns red, then purple, blue, and finishes off in various shades of gray.
"Silver nanoparticles are a bit trickier," said Johnston.
Sizes and shapes determine the color of silver nanoparticles, which can be spheres, triangles, round plates or even prisms. They can be shades of green, yellow or orange.
Besides the cachet that comes with clothing yourself in precious metal, Johnston also claims that the process is environmentally friendly, an advantage over traditional dyes.
The wool is also fade-free, handles abrasion well and eliminates static electricity, said Johnston. The gold nanoparticles never wash out.
Besides, "it's very soft and has a nice appearance with a subtle color," he added.
Precious-metal nanoparticles are not new. Gold nanoparticles have been used unwittingly for centuries in red stained-glass windows and are being explored for their potential medical benefits.
Over the last decade, silver nanoparticles have been added to everything from socks to teddy bears for their antibacterial properties, despite recent findings that suggest their leakage into water systems.
Precious-metal-dyed wool isn't for the everyday buyer, and a gold- or silver-dyed wool sweater will be at least several times more expensive than the average wool sweater. Johnston estimates that a scarf made of the wool, which was displayed at the conference "hot off the loom," will cost between $200 and $300.
"It's the difference between a BMW and a Toyota," said Johnston.
While Johnston won't mention which specific fashion designers he is in talks with, he hopes that the first precious metal dyed garments will appear in a year or so.
"This is very interesting research," said Kevin Conley, a nanotechnology researcher at Forsyth Technical Community College who attended Johnston's presentation but was not involved in the work.
"I think this will put a smile on people's faces and help advance nanotechnology," said Conley.

115-Year-Old's Brain Was Sharp Until the End
A Dutch woman who was the oldest person in the world when she died at age 115 in 2005 appeared sharp right up to the end, joking that pickled herring was the secret to her longevity.
Scientists say that Henrikje van Andel-Schipper's mind was probably as good as it seemed: a post-mortem analysis of her brain revealed few signs of Alzheimer's or other diseases commonly associated with a decline in mental ability in old age.
That came as something of a surprise, said Gert Holstege, a professor at Groningen University, whose findings will be published in the August edition of Neurobiology of Aging.
"Everybody was thinking that when you have a brain over 100 years, you have a lot of problems," he said in a telephone interview on Friday.
He cited a common hardening of arteries and the build up of proteins associated with Alzheimer's disease as examples.
"This is the first (extremely old) brain that did not have these problems."
Van Andel was the oldest living person in the world at the time of her death in 2005 in the Dutch city of Hoogeveen, according to the Guinness Book of World Records.
In 1972, the then 82-year-old Van Andel called the University of Groningen in order to donate her body to science. She called again at age 111 because she worried she might no longer be of interest. At that time Holstege began to interview her, testing her cognitive abilities at ages 112 and 113. Though she had problems with her eyesight, she was alert and performing better than the average 60- to 75-year-old.
Dr. Murali Doraiswamy of the Center for Aging at Duke University, not associated with the study, said it is unusual and valuable.
In the first place there are few "super-centenarians" -- people 110 and older -- alive at any one time, a slim proportion of the world's population and a scant number even compared to those who reach 100 years.
As a result, he said, there are few chances to study brains as old as hers.
"It's very rare to be able to do not only a post-mortem, but also be able to have tested her two, three years before she died," said Doraiswamy.
"For a scientist, getting the opportunity to study someone like that is like winning the lottery."
Doraiswamy, an Alzheimer's expert, said that the proportion of brains with some buildup of proteins associated with the disease increases with age. As a result, experts theorize anybody who lives long enough will get them eventually.
When Van Andel died, the director of the elderly home where she was living declined to give a cause of death, pointing to her extremely advanced years.
Holstege said she died of cancer.
"She died from stomach cancer, and you and I can also die from stomach cancer," he said, adding that her case demonstrates that very old people die of diseases, not simply old age.
"It is very important to treat the elderly as normal people, as if they are 50 or 60."
He noted that Van Andel was operated on at age 100 for breast cancer and survived 15 more years.
When she was born in 1890, she weighed only 3.5 pounds, and her mother expected her to die in infancy. Van Andel's husband died in 1959. She had no children.
Longevity was in her genes, as all her siblings lived past 70, and her mother died at the age of 100.
Asked what advice she would give to people who want to live a long time, she once quipped: "Keep breathing."

Tree Grown From 2,000-Year-Old Seed
Just over three years old and about four-feet tall, Methuselah is growing well. "It's lovely," Dr. Sarah Sallon said of the date palm, whose parents may have provided food for the besieged Jews at Masada some 2,000 years ago.
The little tree was sprouted in 2005 from a seed recovered from Masada, where rebelling Jews committed suicide rather than surrender to Roman attackers.
Radiocarbon dating of seed fragments clinging to its root, as well as other seeds found with it that didn't sprout, indicate they were about 2,000 years old -- the oldest seed known to have been sprouted and grown.
Sallon, director of the Louis L. Borick Natural Medicine Research Center at Hadassah Medical Organization in Israel, updates the saga of Methuselah in Friday's edition of the journal Science.
One thing they don't know yet is whether it's a boy or girl. Date palms differ by sex, but experts can't tell the difference until the tree is six or seven years old, Sallon said.
She hopes there's a chance to use it to restore the extinct Judean date palm, once prized not only for its fruit but also for medicinal uses.
The researchers have had a look at the plant's
DNA, however, and found it shares just over half its genes with modern date cultivars.
"Part of our project is to preserve ancient knowledge of how plants were used," Sallon said in a telephone interview. "To domesticate them so we have a ready source of raw material."
Her Middle Eastern Medicinal Plant Project is working to conserve and reintroduce plants to the region where they once lived.
"Many species are endangered and becoming extinct. Raising the dead is very difficult, so it's better to preserve them before they become extinct," she said.
The oldest documented seed to be grown previously was a 1,300-year-old lotus, Sallon said.

Pink Grapefruit Juice Most Nutritious
Pink grapefruit juice provides more nutrients per calorie than any other 100 percent fruit juice, according to a new study that analyzed several juices commonly found in major U.S. markets.
The pucker-inducing pink drink just edged out orange juice, which also ranked high, but soundly beat white grapefruit, pineapple, prune, grape and apple juices, which rated in that order, with non-citrus juices like apple falling behind high vitamin C content varieties.
Author Gail Rampersaud, a researcher at the Institute of Food and Agricultural Sciences at the University of Florida, told Discovery News that pink grapefruit juice "is an excellent source of vitamin C," providing an entire day’s recommended amount in a single 8-ounce glass.
"It also provides potassium, folate, thiamin and magnesium, as well as certain carotenoids that can be converted into vitamin A in the body," she added. "Pigmented grapefruit juices, such as pink or ruby, also contain lycopene, a carotenoid that gives pigmented grapefruit its rich color."
Carotenoids are color-giving substances found in orange and yellow fruits and vegetables. They are also present in dark green leafy veggies. Prior studies suggest these compounds may help to prevent cancer and other diseases.
For the recent research, Rampersaud focused only on common 100 percent fruit juices. This left out tomato juice, which is primarily marketed as a vegetable juice, and cranberry juice, which most often is sold as cranberry juice "cocktail," with less than 30 percent actual cranberry juice or within a blend of other juices.
Pomegranate, blueberry, cherry and other rich juices also usually come in blends, so they were eliminated for the same reason.
She used six different methods to calculate each juice’s nutrient density, which is defined as either nutrients provided per calorie or the ratio of the amount of a nutrient in foods to the energy provided by these same foods.
One method, for example, involved calculating the average recommended daily value amount for certain known nutrients based on 2,000 kilocalories, or units used to express the energy-producing potential of food. Nutrients included proteins, fats, sugars, numerous vitamins and minerals and other components.
Findings are published in the current issue of the Journal of Food Science.
Rampersaud explained that citrus juices ranked high "because they generally have higher amounts of a wider variety of nutrients compared to the other juices included in the analysis, coupled with the fact that the citrus juices are lower in calories."
In recent years, the U.S. Department of Health and Human Services has urged consumers to focus on nutrient dense foods and beverages to avoid excess calorie intake.
Adam Drewnowski, director of the Center for Public Health Nutrition at the University of Washington, has conducted several related studies.
He told Discovery News that Rampersaud did "a very impressive job."
Drewnowski added, however, that current nutrient density methodologies do not allow for inclusion of phytochemicals and antioxidants, which are substances that, like carotenoids, may also end health benefits.
Earlier studies have found that very dark juices like pomegranate and blueberry, even in blends, provide high amounts of these compounds.
A food to wash down with all of that juice might be spinach, which Drwenowski said is "the most nutrient dense food," along with broccoli and red peppers, which also provide substantial nutritional bang per calorie buck.
