The Central Museum of the Great Patriotic War is dedicated to the Soviet victory in World War II. But on a recent afternoon, American military musicians made up half the band playing the national anthem at the opening of an exhibit telling the story of Joseph Beyrle, one of the few men to fight the Nazis in both the U.S. and Russian armies.

A 19th-Century Mathematician Finally Proves Himself

, , , ...

by Laura Sydell

Charles Babbage, the man whom many consider to be the father of modern computing, never got to complete any of his life's work. The Victorian gentleman was a brilliant mathematician, but he wasn't very good at politics and fundraising, so he never got the financial backing to finish any of his elaborate machine designs. For decades, even his fans weren't certain whether his computing machines would have worked.

But Doron Swade, a former curator at the Science Museum in London, has proven that Babbage wasn't just an eccentric dreamer. Using nothing but materials that would have been available to Babbage in the 1840s, Swade and a group of engineers successfully built Babbage's Difference Engine — and a version is now on display at the Computer History Museum in Mountain View, Calif.

I have seen it in person and it is amazing to see it work and it work very well and the results are accurate

Interesting fact:
It weights 5 tons (cast iron, steel and bronze) woven together from 8,000 distinct parts

Al-Qaida Victims Are Overwhelmingly Muslim: Study

, , , ...

By Kevin Whitelaw

Al-Qaida leaders frequently claim they don't target Muslims, but the victims of the terrorist group's attacks have been overwhelmingly non-Western, according to a new study.

Between 2004 and 2008, only 15 percent of the 3,010 people killed in 313 confirmed al-Qaida attacks were Westerners, according to the report by the Combating Terrorism Center at the U.S. Military Academy at West Point.

The figures are even more striking in recent years -- only 2 percent of the victims were Western between 2006 and 2008. The remaining 98 percent were inhabitants of Muslim-majority countries.

The report is squarely aimed at persuading Muslims around the world that al-Qaida's violence is indiscriminate. Researchers, for example, relied solely Arabic press accounts to assemble their data on casualties.

"This allows researchers to avoid accusations of bias associated with Western news outlets or U.S.-based datasets," the report says.

And at least some Arabic media outlets have already taken note. The Kuwaiti newspaper al-Jarida printed the study's findings under the headline "The Land of Islam is burned with the Terrorism Fire of al-Qaida Organization. Muslims Victims 98 % Foreigners 2%."

U.S. intelligence agencies believe that al-Qaida is still actively plotting to strike in Western countries, but it has become more difficult for them in recent years.

In 2004 and 2005, Al-Qaida did manage to stage attacks in London and Madrid that killed a number of Westerners. But more recently, it has struggled to strike outside of Muslim-dominated nations.

There were no Western fatalities from the group's attacks in 2006, while half of the 12 deaths in 2007 and 2008 came in an attack on a Marriott Hotel in Islamabad, Pakistan, according to the report.

"Al-Qaida has acknowledged that assailants should be patient and wait for the right time to carry out attacks (in martyr videos and announcements), but this report shows there is scant evidence of prudence or effort to limit violence," the report concludes. "Irrespective of al-Qaida's justifications, if history provides a glimpse into the future, the group and its associates will pose the greatest threat to fellow Muslims."

When was the last time you actually set pen to paper and mailed off a personal letter to someone? It's probably been awhile — and the man to blame is Ray Tomlinson.

Back in 1971, Tomlinson was a young engineer at the Boston firm of Bolt, Beranek and Newman — known today as BBN Technologies. He'd been given a task: Figure out something interesting to do with ARPANET, the newborn computer network that was the predecessor of the modern-day Internet.

Flu Attack! How A Virus Invades Your Body

, ,

by Robert Krulwich

It starts very simply. A virus, just one, latches on to one of your cells and fools that cell into making lots more. Lots, lots more, like a million new viruses. This animation shows you how viruses trick healthy cells to join the dark side.

David Bolinsky and his team at XVIVO designed this animation for a research company called Zirus (and we thank Zirus for letting us play with their pictures). Bolinsky says what you see in the video actually happens much, much faster in real life — in a fraction of a fraction of a second. So this is a very slow motion version of cellular activity.

And for those of you who were wondering, yes, the designers did add color. Proteins, DNA, organelles, and the teeny things inside a human cell are so small, and the insides of cells are so dark, that for all practical purposes, they are colorless.

So the copying molecule isn't really pink. But once you decide to colorize, pink is just as accurate as maroon or yellow.


One Last Thing

In our video we ask, if a flu virus inside your body can multiply by the millions within seconds, why don't we topple over and die quickly?

Here's a better, longer answer than the one in the video. First, some new viruses get caught in mucus and other fluids inside your body and are destroyed. Other viruses get expelled in coughs and sneezes. Second, lots of those new viruses are lemons. They don't work that well. Some don't have the right "keys" to invade healthy cells so they can't spread the infection. And third, as the animation shows, your immune system is busy attacking the viruses whenever and wherever possible.

That is why most of the time, after a struggle (when you get a fever and need to lie down), your immune system rebounds, and, in time, so do you.

Bionic Eye Opens New World Of Sight For Blind

by Jon Hamilton

October 20, 2009

Stem cells and electronics can help restore vision to people who've been blinded by retinal diseases, scientists reported in Chicago at Neuroscience 2009, the annual meeting of the Society for Neuroscience.

Diseases of the retina cause blindness by damaging the cells that line the back of the eye, where images of the world are normally transformed into nerve impulses that go to the brain.

Tips For Preventing Swine Flu

, , , ...

by Linton Weeks

NPR.org, April 27, 2009 · As it investigates recent incidents of swine influenza in humans, the U.S. Centers for Disease Control and Prevention is stressing prevention.

The agency has posted several Web pages dealing with swine flu, including a list of what you can do to forestall this — or any — infectious disease.

The CDC recommends taking these everyday precautions:

• Avoid contact with people if you, or they, are sick.

• Stay at home — from work, school or other public activities — when you are ill.

• Shield others from your coughs and sneezes by using a tissue.

• Wash your hands often.

• Keep your hands away from your eyes, nose or mouth.

• Maintain healthful habits — get ample sleep and exercise, drink fluids, eat well.


Currently, there's no vaccine for humans that prevents swine flu, though scientists are currently working on one. But there is a vaccine for some forms of swine flu in pigs.

Which suggests one more precaution particular to this outbreak: Avoid unnecessary contact with live pigs. (It's safe to eat pork, but not pet a pig.) But that alone may not roadblock the spread of swine flu this time around. In pigs, this virus is causes a respiratory illness that's highly contagious, but usually not fatal.

As seen with bird flu, people coming into contact with infected animals occasionally become sick themselves — but the virus usually stops there. Rarely have humans infected other humans with bird flu — or swine flu. With the current swine flu outbreak, the swine flu virus has transformed, appearing to increase its ability to spread between humans.

"We've seen swine influenza in humans over the past several years, and in most cases, it's come from direct pig contact. This seems to be different," said Arnold Monto, a flu researcher with the University of Michigan told the Associated Press. "I think we need to be careful and not apprehensive, but certainly paying attention to new developments as they proceed."

At this point, the CDC and other government organizations are focusing on getting the message out to individuals about how to respond to the threat of influenza. Public health officials are monitoring the various cases and conducting epidemiological research on the virus.

"If the outbreak turns into a full blown epidemic," says Andrew Pekosz, an associate professor at the Bloomberg School of Health at Johns Hopkins University, "the government will have the right to place limitations on travel and gatherings of groups of individuals." Schools may be closed or sporting events canceled, Pekosz says, and officials will implement quarantine procedures for hotspots of cases and begin distribution of antiviral drugs.

All these steps, Pekosz says, are necessary "to limit the epidemic and slow virus spread."

Jeanne Matthews, an assistant professor at the Georgetown University School of Nursing and Health Studies, says health officials are "so dependent on whether it appears that community containment might halt person to person contact. This is a new strain. I don't think we know enough about this flu to have a sense of when that should be."

When It Comes To Shampoo, Less Is More

,

by Allison Aubrey

Morning Edition, March 19, 2009


Americans love to shampoo. We lather up an average of 4.59 times a week, twice as much as Italians and Spaniards, according to shampoo-maker Procter & Gamble.

But that's way too often, say hair stylists and dermatologists. Daily washing, they say, strips the hair of beneficial oil (called sebum) and can damage our locks.

Shampoo Is Big Business

The current trend of frequent shampoos may have started on May 10, 1908, when the New York Times published a column advising women that it was OK to wash their hair every two weeks. At that time, once a month was the norm.

Decades later, TV marketing campaigns began to convince us that daily washing was the thing to do. A 1970s Faberge ad for Farrah Fawcett shampoo is one example.

"All you have to do is watch her running in slow motion on a beach with her hair flopping gracefully in the wind," says Steve Meltzer, a former ad executive. The idea was, "Wash your hair with this stuff, and you, too, can be like Farrah Fawcett," Meltzer says.

Madison Avenue sold people on the idea that they could shampoo their way back to beauty.

Ads also convinced us that daily hair washing is healthy. Remember the Breck girls? Or how about Christie Brinkley's body-building for hair ad with Prell?

Skipping Shampoos Is, Well, Un-American

Americans took easily to the idea that we should shampoo frequently. And lots of us find it disgusting to shampoo any less than once a day. Take some fitness-conscious college students from Georgetown University, for example. When I told them about the old-time advice to wash once a month, they almost gagged.

"That is way too little hair shampooing," laughs Jane Caudell-Feagan.

"If I don't shower every day, my hair gets greasy, so I think it's completely heinous," says her friend Ashley Carlini. After a workout, they say, it would be disgusting not to wash your hair.

Eco-Conscious 'No-'Poo' Movement

Given our cultural propensity to lather up frequently, it may be shocking that in some eco-conscious circles of society, some people are giving up shampoo.

"There's a lot of people doing this no-shampoo movement," says 20-something blogger Jeanne Haegele. She writes a blog called LifeLessPlastic.

In an attempt to buy fewer items with plastic packaging, Haegele recently went three months without using any shampoo. Instead, she washed her hair with baking soda twice a week and conditioned it with a vinegar rinse.

She says her hair didn't smell, and her friends were very supportive. "Maybe they were secretly wondering why I smelled like a jar of pickles," she says jokingly.

She ended the no-'poo experiment after developing a bad case of dandruff, but Haegele says she might try it again.

She recalls the biggest surprise was that her hair didn't get very greasy. For now, she's using shampoo bars a few times a week.

Dermatologist Recommends Shampooing Less

Experts say Haegele's observations are not flaky. As she washed less, her sebaceous glands began producing less sebum oil.

"If you wash your hair every day, you're removing the sebum," explains Michelle Hanjani, a dermatologist at Columbia University. "Then the oil glands compensate by producing more oil," she says.

She recommends that patients wash their hair no more than two or three times a week.

There's also a lot of variation among hair types. African-Americans and people with curly hair can go even longer between washes compared to folks with straight hair.

So, it seems, less is more. And maybe our grandmothers were on to something after all.
