The Brains Behind a NASA Satellite

Not the chip from this story, but another CAMBR processor. Note the intricate layout of teeny, tiny circuits.

Not the chip from this story, but another CAMBR processor. Note the intricate layout of teeny, tiny circuits.

Riddle me this: How many University of Idaho microprocessors does it take to equal the computing power of 17,000 Intel quad core processors?

Answer? Just one, my friend.

And because it is designed to operate in space, in runs on only 120 watts of power, slightly more electricity than is used by your average light bulb.

The Center for Advanced Microelectronics and Biomolecular Reserach (CAMBR) is a research center located an hour and a half north of Moscow in Post Falls, Idaho. Besides creating biomolecular sensors with nanotechnology capable of detecting disastrous diseases such as MRSA, CAMBR is one of the leading providers of advanced processors for NASA space missions.

This particular chip was created for the GeoSTAR satellite mission designed to observe hurricanes and other major storm systems across the United States in order to better understand and predict them. And by observing, I mean pointing a ton of antennas and hardware capable of scanning much more than what the visible eye can see.

In fact, the satellite is designed to operate 588 antennas in perfect synchronization. This incredible task is the reason the new microprocessor was required.

The processor was created in a race against the clock, going from preliminary design to testing in less than seven months. Creating any piece of new technology in that time frame would be difficult, but CAMBR upped the ante by incorporating two new technologies. One the center had simply never used before, and the second was actaully pioneered by the facility.

Microprocessors typically receive power from the edges of the chip where it connects to the rest of the computer’s infrastructure. Because power is lost as it travels across the chip, they tend to suck up a lot of it in order to get electricity to the components in the middle. The CAMBR team solved this problem by implementing a technology that uses small half-spheres spread out over the chips entire surface to evenly distribute the power.

The second technology involved the use of IBM facilities capable of laying down circuits only 90 nanometers thick - about the width of a human hair. While private companies have been able to make chips with circuits this small for some time, none of them had to make their chips impervious to the hazardous radiation found above the Earth’s atmosphere.

Finding away around that conundrum was a CAMBR first and a technology that recently received a $1.6 million grant to develop further. The funding agency was the Defense Advanced Research Projects Agency/Space and Naval Warfare research program. So look for the chip to be defending our country from advanced weaponry in the future.

Watching the Clouds… in Greenland

One of the research buildings at Summit Station, Greenland.

Several weeks ago, Professor Von Walden made several contributions to VandalScience while traveling to Summit, Greenland. His posts spoke of -26 degree Celsius temperatures, cramming into a C-130, research buildings on skis and details on his visit to the future research site.

Today, the Spokesman-Review printed a story written by Becky Kramer about his research plans. The piece does an excellent job outlining the scope of his five-year project and the reasons for conducting the research. Here are a few choice excerpts.

“Associate geography professor Von Walden and colleagues at two other universities want to know if Greenland’s cloud cover is getting thicker. The answer could have important ramifications for rising sea levels.

‘We know that clouds are important in polar zones. They trap heat,’ Walden said. ‘If the cloud properties are changing over time, as a result of climate change, that could dramatically affect the amount of energy that returns back to the ice sheet from the atmosphere.’

The initial work will establish baseline cloud conditions, Walden said. After four years, the researchers hope to continue the work through additional grants.”

So, in short, Von Walden and his associates are going to observe many properties of the clouds, atmosphere and climate at the highest point in Greenland. Several instruments will be operating year-round to take measurements of temperature, precipitation, cloud thickness, energy transfer rates and even the motion of individual particles in the cloud down to the millimeter.

By itself, this data won’t solve the climate change mystery. However, when the data is added to climate change models in conjunction with many other observational projects, the result will be a much clearer and more accurate view of future weather.

There are many who debate whether or not the Earth is really warming. Still others argue that while the climate is changing, humans have little or nothing to do with the phenomenon. However, I don’t think anyone will argue that doing the research to find the answers is a bad idea. Projects such as these are crucial for gaining a better understanding of our environment and all of our futures.

Fighting Gridlock With Science

Monday, September 28th, 2009

The next time you’re sitting in your car smack dab in the middle of a massive gridlock traffic jam, don’t curse the other drivers. Instead, curse the city planners who didn’t attend their summer school.

Though many traffic issues are simply unavoidable, improvements to traffic flow can be made through research and understanding of patterns and use.

In fact, since 2000, the University of Idaho’s National Institute for Advanced Transportation Technology (NIATT) has trained engineers across the country to fight gridlock via two innovative programs. Those innovations have been recognized with a national education award.

The Institute of Transportation Engineers recently presented NIATT with the 2009 Transportation Education Council Best Innovation in Education Award for its Traffic Signal Summer Workshop and Mobile Signal Timing Training (MOST) course. These educational efforts are intensive immersion workshops, the former features five days hands-on learning during a summer course and the latter uses computer-based workshops with new simulation technologies.

The Traffic Signal Summer Workshop ran from 2000 to 2007 and gave more than 80 students from more than 30 universities from around the U.S. and Canada the chance to get hands-on experience with traffic control systems. The program’s innovation came in the form of a controller interface device (CID) that allowed field hardware to be integrated with simulation software. The resulting simulation setup gave students in the lab experience with actual transportation system devices.

Since its invention, the CID has been improved to connect commonly used traffic simulation models with most widely used traffic controllers. The CID’s usefulness has led to the sale of more than 130 of the devices to more than 40 different groups across the country.

Eliminating traffic jams across the country; just one more way the University of Idaho is helping to make the country a better place to live.

Water on the Moon

Thursday, September 24th, 2009

Today researchers report in the journal Science that they have discovered water on the Moon!  Now, when they say they have discovered water, don’t start thinking about rain, rivers, or lakes.  We’re talking about microscopic amounts of water.  Nevertheless,  there is enough of it that, with the proper technology, we could extract it for the use of astronauts exploring the Moon.

Water on the Moon is a huge discovery.  Ever since the days of Apollo, we have thought that the Moon didn’t even have these microscopic traces of water.  The Apollo astronauts brought Moon rocks back to Earth with them, and they were analyzed to high sensitivity in laboratories here on Earth.  It is these analyses that led to the idea that the Moon was totally devoid of even microscopic traces of water.  Unfortunately, the containers these samples were returned in weren’t sealed properly due to the lunar dust getting stuck in the seals.  So  even if the samples did originally have some water molecules, it is possible that they escaped before they got to the laboratories.

The evidence for water on the Moon is piling up.  The most recent find is by NASA’s Moon Minerology Mapper (M3) instrument which orbited the Moon on India’s Chandrayaan-1 spacecraft. M3 carried a spectrometer that observed an absorption band in the infrared at 3.0 microns — a spectroscopic absorption that could only be produced if the spectrometer was looking at water molecules.  Data from two other missions, EPOXI and Cassini, corroborate this finding.

So where does this water come from?  After all, if you poured a cup of water out on the lunar surface, it would promptly evaporate.  Preliminary speculation is that water is actively being formed on the Moon by the interaction of hydrogen in the solar wind and oxygen in the lunar surface rocks.

Burning Rubber for Newton

Wednesday, September 23rd, 2009

As an aerospace engineer and constant reader of breaking science news, I sometimes forget that it is just as important to teach the basics as it is to push the boundaries of new frontiers.

But Professor David McIlroy remembers.

McIlroy teaches a class called “Physics in  Your Everyday Life,” which strives to demonstrate basic properties and laws of physics in easy to understand, everyday examples.

Yesterday morning in the Kibbie Dome’s parking lot, McIlroy demonstrated Newton’s laws of motion with the help of his 1972 Dodge Charger touting a 440 cubic inch engine. The classic muscle car burned some rubber in the name of Newton.

Newton’s First Law states that an object at rest will stay at rest unless acted on by an outside force. When the Charger’s tires spin out, it means the amount of friction between the tires and the road is not enough to move the car forward.

To demonstrate how traction - or the coefficient of friction - affects the tires, McIlroy launched the car from normal asphalt, wet asphalt and asphalt with sand sprinkled on top. As the traction got progessively worse, the car’s tires spun more and it took longer for the car to accelerate.

Afterward, McIlroy proved that sometimes less is more by using some restraint and accelerating with a lighter touch.

You can see some photos of the event in today’s edition of the Moscow-Pullman Daily News.

Global Cooling?

Tuesday, September 22nd, 2009
Someone with a spare glove and a sense of humor lives in Moscow, Idaho.

Someone with a spare glove and a sense of humor lives in Moscow, Idaho.

Here’s a report from Europe that really surprised me.

Mojib Latif of the Leibniz Institute of Marine Sciences at Kiel University, Germany - one of the lead authors of the United Nations Intergovernmental Panel on Climate Change (IPCC) recently announced he believes the world is going into a couple decades of global cooling.

If you’re unfamiliar with the IPCC, it is the international body of scientists who put out a report on global climate change every five years. And each of their past few reports have unequivocally stated that the Earth is rapidly heating, we are the cause of the change and that the world is on a disaster course that could culminate in global devastation by 2100.

But something has been happening to the weather over the past few years that none of them saw coming.

“The strong warming effect that we experienced during the last decades will be interrupted. Temperatures will be more or less steady for some years, and thereafter will pickup again and continue to warm.”

That was part of the message Latif delivered to more than 1500 of the world’s top climate scientists in Geneva during a recent conference. And he’s not alone. More and more climate change scientists are beginning to report a recent cooling trend and predicting that it will last a decade or more.

But you don’t hear a peep from the national media about this. Some people would argue that it is because they don’t want to look like fools, having preached global annihilation for the past 10 years. Others would argue that because the new data doesn’t stir sensationalist headlines, it just doesn’t make for good news. Whatever the reasons, I’m actually glad that this is being ignored.

If these headlines got out in the same large and loud ways the national media has previously shouted research on global climate change, the general public would get the wrong message. They’d see this as evidence that scientists are wrong, that science is a sham and that nobody really knows anything. All faith would be lost in the scientific community - at least where global climate change is concerned.

What the general public - and the national media - often fail to understand is that science is a process and is always based on the assumption that what you think is wrong. A researcher makes a best guess or assumption about the way the world works, and then goes to try to disprove the theory. If the theory holds up again and again, then it becomes accepted as truth.

At least until someone disproves it.

This report on global cooling is no different. The best and brightest minds the world has to offer are trying to create their best guess as to what the future holds for the world’s climate. Along the way, they constantly test their theories, make changes, update models and put new information into the calculations. Add to the equation the fact that the weather is hugely unpredictable and the result is simply a best guess, especially when it comes to the short term, and you’re bound to get some irregularities.

We all know the weather trends in the places we live. I know - based on prior experiences - that it is going to get really cold this winter and then warm up again when spring comes. But I have no clue what the weather is going to be like tomorrow. Or even next week. Logic tells me that because it is most likely going to become winter in a few months, that next week will be colder than this week.

But it doesn’t have to be.

In much the same way, predictions that the Earth will be much warmer in 200 years does not mean that the world has to be warmer next year. There are just too many variables involved on a short-term basis.

Nonetheless, some people will cite this cooling trend as evidence that global warming is a sham and that scientists are wrong.

Maybe they are.

But we’re talking about hundreds of people who are much, much smarter than I am, who have devoted their lives to the study of climate change. If their best guess is that our pollution is causing the world to warm up at dangerous levels, then I’m going to listen.

And if by some chance they’re wrong, what’s the harm in cleaning up our act and putting less pollution in the world?

Decaf and Nuclear Waste, Together at Last!

Friday, September 18th, 2009

Professor Chien Wai in his lab.

I know what you’re thinking. There’s no way that decaf and nuclear waste go together in any way that could possibly be beneficial, let alone harmless.

But there is.

It turns out that the same basic principles used in the decaffienation of coffee beans and the extraction of alpha acids from massive amounts of hops can also be used to extract usable enriched uranium from the ashes of low-level radioactive waste. The discovery of this process by Chien Wai is just one of several inventions from the University of Idaho that has been licensed to private companies.

In this case, the buyer was international nuclear giant AREVA. They’re taking the technology and constructing a recycling plant near Richland, Washington that will immediately start working on 32 tons of incinerator ash currently sitting around at the nearby enrichment plant.

Curious about the details? Well, read on my friend.

Low-level nuclear waste includes common, everyday objects like air filters, gloves and lab coats that slowly become contaminated during their use anywhere that uses radioactive materials. The most common producers of this type of waste are nuclear energy plants, uranium enrichment plants and hospitals, among others. The sheer volume of this waste is difficult to deal with, so many institutions are allowed to burn it, reducing its volume by 90 percent.

But it turns out that nearly 10 percent of that waste is usable enriched uranium meaning that there is currently about $5 million worth of nuclear fuel just sitting around in the Washington desert.

And nearly 40 years ago, Wai decided to go get it.

The process of decaffeinating coffee beans involves supercritical carbon dioxide. We all know CO2 as a gas or bubbles in our soda. But raise the temperature and pressure just a little bit, and the gas takes on the properties of both a liquid and a gas. It can move directly into a solid object like a gas and dissolve chemicals and compounds like a liquid.

But because CO2 cannot directly dissolve metals, a binding agent called a ligand must be introduced to the equation. Once the ligand is applied, the supercritical CO2 flows through the waste, dissolving both the ligand and the metals bounded to it. Then, when the CO2 is returned to normal pressure, it becomes a gas and evaporates, leaving behind only the extracted metal; enriched uranium in this case.

So in the end, tons of enriched uranium that was previously harmful to the environment will be extracted and reused for energy. The formerly radioactive ash pile will be easier to manage and the whole process is environmentally friendly. No solvents are used, no acids applied and no organic waste is left behind.

If all goes according to plan, the recycling plant will get through the waste in Richland and begin taking in similar waste from other sites around the country. Tons of formerly dangerous waste will no longer be harmful, tons of usable nuclear fuel worth millions of dollars will be recovered, the plant will provide jobs for the community, money will be made for the state of Washington and the University of Idaho, and similar plants will be built around the world.

If you’re looking for global impact, look no further than the technologies coming out of the University of Idaho.

Curious for even more details? See the University of Idaho’s press release, AREVA’s press release or the Idaho Alumni Magazine article on page 20 of the PDF.

Capitalizing on Innovation

Thursday, September 17th, 2009
President Duane Nellis.

President Duane Nellis.

It’s not everyday that you hear someone say an institution should not be afraid to make money.

But during a meeting of the faculty of the University of Idaho yesterday afternoon, that is exactly what President Duane Nellis said. In times of economic recession and deflating budgets, it is up to the university to seek sources of funding outside of the state government. This point was punctuated by his announcement that the state of Idaho would likely be asking for a mid-year return of funds it provided for the fiscal year.

So where should the university turn? Capitalism. The free market. Our own ingenuity.

The University of Idaho is a breeding ground for great ideas that could earn the university additional dollars. But for whatever reason, there is typically a stigma attached to marketing inventions born from a campus. After all, don’t the taxpayers help fund the research that produces these potentially lucrative ideas? Shouldn’t they get some of the money?

Well, yes. And they do. When the university receives funds, it helps it accomplish its mission, which is to serve the entire state of Idaho.

This fact is not lost on President Nellis, nor on Governor Butch Otter.

A press release was issued yesterday announcing the Governor’s Innovation Summit that will highlight Idaho’s creative entrepreneurs and hopefully promote the leveraging of future high-tech innovations.

“We need to find better ways to unleash the potential of the great minds we have at Idaho’s colleges, laboratories and businesses,” Governor Otter said in the press release.

I couldn’t agree more. What are your thoughts?

Stay tuned for highlights of some of the innovative technologies that have been transformed into licenses and business from the University of Idaho’s laboratories.

Idaho’s Eagle Eye

Wednesday, September 16th, 2009

Last night I watched the movie Eagle Eye where a massively complex artificial intelligence system hijacks any electronic device connected to the nation’s network in any way, shape or form in an attempt to assassinate the President and his entire line of successors.

The movie plot is obviously out of this world (right?!?!) but it fits amazingly well with some exciting news recently reported about a University of Idaho faculty member located in Boise.

Rick Allen works with GIS technologies (using satellite data for research) from the Research and Extension center at Kimberly, Idaho. Specifically, he develops computer programs to model and measure various aspects of agriculture using satellite data.

Allen and two of his colleagues, Bill Kramber  and Tony Morse from the Idaho Department of Water Resources, created a method that uses infrared images to measure evapotranspiration rates, which can be used to determine how much water a field is using.

Evapotranspiration is the combined amount of water evaporating from the soil and from the leaves of the crop. Higher rates appear cooler on infrared images and point to fields using high amounts of water.

So why is this important?

“It is so powerful because we know that every field has its own behavior, its own characteristics, its own rate of development,” said Allen in a NASA video about the project. “We are now able to pinpoint water consumption on a field by field basis, which has never been possible before. We are convinced that over the next 20 or 30 years, we will have millions of people in developing countries impacted with a more sustainable food supply brought by better management of water. And that water management is going to be propelled by the use of satellite technology.”

The work is so important that the project won the prestigious national innovations in American Government Award from Harvard University’s Ash Institute for Democratic Governance and Innovation. Of the 700 projects that were nominated, only 6 were selected.

The satellite data used in the process comes from NASA’s LandSat satellites, which can map areas as large as 6.4 million acres - 10,000 square miles - and get readings on individual fields as small as 40 acres.

Thankfully, this is a far cry from Big Brother peering into my living room window from space. So long as they keep these technologies to wonderful uses such as this, I say bring on the Eagle Eye!

Ever Heard of Norman Borlaug?

Tuesday, September 15th, 2009
Norman Borlaug

Norman Borlaug

Have you ever heard of Norman Borlaug? One of four Americans to ever win the Nobel Peace Prize? A man who single-handedly saved up to a billion lives around the world?

If the answer is no, don’t worry, you’re not alone. I’d never heard of him either.

Until today.

Borlaug passed away Saturday night. I’m slightly ashamed to say I’d never heard of the father of the Green Revolution; the man Penn and Teller called history’s “greatest human being.” So I’m taking the time to talk about his accomplishments and the issue he devoted his life to: saving the world from hunger.

In the 1960’s many politicians and scientists were warning of a world famine. India’s population was growing faster than their food production, as was the case in several countries. Borlaug’s solution was to introduce a new strain of wheat that produced much higher yields to countries that traditional farmed rice, lentils and cassava. He also advocated the use of synthetic fertilizer and modern irrigation systems.

The result? India and Pakistan make enough food to feed themselves. The world’s food production over the last half-century rose 170 percent while using only 1 percent more land. Billions of people may have been saved from starvation without losing innumerable natural land preserves to agricultural production.

Borlaug attempted to take his same successes to Africa where the food crisis has never been solved. However, his efforts were blocked by environmentalists and interest groups both home and abroad.

Why? Some supported taking the money needed to bring high-yield crops to Africa and instead applying it to efforts intended to reduce global warming. Some claimed the increased use of synthetic fertilizers would bring ecological disaster to Africa. Still others advocated it would be best for Africa to maintain the use of their traditional methods to grow local, traditional crops.

One, is it better to make the world potentially slightly cooler 100 years from now or unquestionably feed tens of millions of malnourished people now? Two, synthetic fertilizers only replace chemicals already found in soil. It is the use of pesticides - which Borlaug despises - that wreaks havoc on the environment. Three, is it ecologically better to bring in new methods and technologies to fully develop land already in use or to slash-and-burn countless acres of natural wilderness?

Here are some telling quotes from a great article from The Atlantic Monthly.

“Waggoner calculates that India’s transition to high-yield farming spared the country from having to plough an additional 100 million acres of virgin land — an area about equivalent to California.”

“As the former Indian diplomat Karan Singh is reported to have said, ‘Development is the best contraceptive.’ In subsistence agriculture children are viewed as manual labor, and thus large numbers are desired. In technical agriculture knowledge becomes more important, and parents thus have fewer children in order to devote resources to their education.”

“Though some mythology now attributes the Dust Bowl to a conversion to technological farming methods, in Borlaug’s mind the problem was the lack of such methods. Since then American farming has become far more technological, and no Dust Bowl conditions have recurred. In the summer of 1988 the Dakotas had a drought as bad as that in the Dust Bowl, but clouds of soil were rare because few crops failed.”

“Borlaug’s reaction to the campaign was anger. He says, ‘Some of the environmental lobbyists of the Western nations are the salt of the earth, but many of them are elitists. They’ve never experienced the physical sensation of hunger. They do their lobbying from comfortable office suites in Washington or Brussels. If they lived just one month amid the misery of the developing world, as I have for fifty years, they’d be crying out for tractors and fertilizer and irrigation canals and be outraged that fashionable elitists back home were trying to deny them these things.’”

Thanks to the TierneyLab Blog for bringing this issue to my attention.

Here’s to the life of one of the world’s greatest humanitarians. May his passing help promote the dreams of his life.
