A report in this week’s journal Nature looks at how thawing ground up North might
impact global warming. Amy Mayer spent some time in Interior Alaska with
scientists at Eight Mile Lake:

Permafrost is ground that’s supposed to be frozen all the time. But for decades it’s been
thawing in places.

When that happens, carbon gets released—potentially contributing to the greenhouse
effect.

Ted Schuur’s a biologist at the University of Florida but he spends his summers doing
experiments near Healy, Alaska.

I tagged along during some field visits.

I met Schuur when we were both living in Fairbanks. He lives far away now, but loves
Alaska. You only work here year after year if you do. Summer field work is brutal – tons
of mosquitoes and you work all the time because the sun doesn’t set.

Pretty soon, we’re there.

“This has to be one of my more photogenic field sites that I ever worked at.”

Tundra surrounds us. We’re just north of the Alaska Range. I can see the snow-capped
peaks. We change into rubber boots, pick up our packs, and, after a few steps, we’re on
the tussocks.

Alaskans often say walking on tussocks is like balancing on basketballs. It’s not easy. If
your feet slip off, they get wet. Schuur’s tall and used to this, so he goes faster than me,
and with less bumbling.

Soon, we’re balancing on lumber instead. Schuur and his group try to protect the areas
where they work with narrow boardwalks.

“When we first came out here, we put these boardwalks that we’re walking on now, big
10 feet pieces of lumber – they’re like 2x6s or 2x8s. But we don’t really want to walk on
the tundra because we come here a lot and you’d end up with a trail in no time and
destroy vegetation.”

Schuur knows trudging across the tundra damages it and he tries to minimize that harm.
But in order to answer his questions about the potential greenhouse effect from thawing
permafrost, he has to dig in.

Schuur saws into the tundra with a bread knife.

“It’s very satisfying. It’s like cutting a big cake – though this is a cake with lots of roots in it.”

He cuts up the plants and packs the roots and the tops into jars.

“We’re going to measure respiration of plants.”

Schuur uses a machine to scrub out the carbon from the air that’s in the jars. The plant
tops and roots will continue to respire carbon dioxide until they die. Later, he’ll use fancy
equipment to “date” the carbon that’s left.

He needs the age of the carbon because when he finds older carbon he knows it’s only
recently escaped the frozen ground. That makes it extra in the system.

At first, Schuur learned, new carbon coincides with more plant growth that uses up the
addition. That means no greenhouse effect.

But, later, the permafrost keeps thawing, more old carbon becomes available, and plant
growth just can’t keep up. That means, carbon dioxide ends up in the atmosphere from
the thawing permafrost – just like it does from burning coal or gasoline.

The thawing may ultimately be a bad thing, but to understand and explain it further,
Schuur wants to document it – or even cause some. Next, he says…

“As strange as it seems, I would love to thaw permafrost on a large scale,
experimentally.”

The dilemma, of course, is that causing a thaw means contributing to – in a small way –
a process that might damage or destroy the ecosystem. But we all emit carbon dioxide,
just by driving.

“Even as I do that and I do an experiment where I melt out a little bit of the permafrost, I
think we’re generating this information that’s helping society answer these huge
questions.”

Schuur says the amount of tundra he’d sacrifice is tiny relative to the whole circumpolar
region, where tons of carbon waits in ground that is frozen now but could eventually
thaw.

Uncovering the Baby Mammoth

The National Geographic Channel is airing a documentary called “Waking the Baby Mammoth” this Sunday. The discovery of an intact baby mammoth carcass is also the cover story of the May edition of the National Geographic Magazine. Lester Graham has more on that:

Transcript

The National Geographic Channel is airing a documentary called “Waking the Baby Mammoth” this Sunday. The discovery of an intact baby mammoth carcass is also the cover story of the May edition of the National Geographic Magazine. Lester Graham has more on that:

(National Geographic) “This is the story of a nomadic reindeer herder, an extinct baby wooly mammoth, and a team of scientists on a quest to learn her secrets…”

One of the scientists on that quest is Dan Fisher. He’s a paleontologist at the University of Michigan.

This nearly 40,000 year carcass is the most complete baby mammoth ever discovered. The scientists named it Lyuba.

Fisher flew to Russia two years ago to get his first look at the mammoth, an animal that’s been extinct for thousands of years.

“It’s overwhelming really to feel the privilege of getting to be that close to something that does hold so many answers to questions many people have.”

Graham: “This was a fascinating find, but I wonder how much has it added to our knowledge of that period.”

“What it tells us about the period is that it was really a wonderful time to be a mammoth – to be a large mammal – on the open steppes of the high north.”

(National Geographic) “For paleontologists this is a time capsule from the Ice Age. When Lyuba lived, the mammoth steppe was at its peak. It was rich with vegetation that sustained millions of woolly mammoths for hundreds of thousands of years.”

An autopsy of the baby mammoth revealed a lot about where she died – 40,000 years ago a dry grassland. Today it’s a frozen tundra in Siberia.

Dan Fisher says the well-preserved carcass still had traces of what Lyuba ate.

“It’s remarkable that we can take evidence that’s with us today, that’s at our fingertips and generate from that new understanding that can give us perspective on big questions like extinction and climate change, issues that we certainly will have to continue to face as we deal with other endangered species and with the future of our own civilization and planet.”

Fisher says the mammoth remains help add to our understanding of a related animal still around today, the elephant. And they help us better understand our impacts on other endangered species.

And Fisher says learning more about the climate 40,000 years ago can help us understand one other thing.

“We want to, of course, understand the Earth’s climate system better and one of the ways we can test the computer models that help us to project patterns of climate change into the future is to essentially try them out on the past. The past is essentially the training wheels for learning to refine these models. So, information from Lyuba and other mammoths can help us to develop a better understanding of how the Earth’s climate system works.”

(National Geographic) “Dan Fisher and his colleagues will continue to unravel Lyuba’s secrets and to search for reasons why mammals went extinct at the end of the Ice Age.”

The National Geographic program indicates research continues to reveal a lot about Lyuba’s life, and her death, which the scientists begin to piece together in the documentary.

Scientists are asking citizens to pay attention to plants this spring. They want you to report everything from leaf buds to blossoms. Scientists want those observations from right in your backyard to better understand how climate change is affecting plants and trees. Sadie Babits liked the idea and signed up:

You know, I found it really isn’t hard to be a citizen scientist.

I’m on the website for Project Budburst. It’s a nationwide effort to get people out into their backyards to track spring flowers. All I have to do is to pick a plant or tree to keep an eye on and then report my findings.

I’m thinking I’ll check out the lilac trees in my neighborhood here in Portland. But before I head out, I need some advice.

So I called Sandra Henderson. She’s busy these days directing Project Budburst at the University Corporation of Atmospheric Research.

“Hey Sadie.”

I reach Henderson at her office in Boulder, Colorado.

What advice do you have for me, a first citizen scientists observing phenology?

“The ideal thing to do is get a sense of when lilacs in your case in Portland, Oregon are expected to have different pheno events.”

Good thing I looked up phenology before calling Henderson. Basically it means nature’s calendar – the timing of when cherry blossoms bloom or a robin builds a nest.

And these life cycles of plants and animals are sensitive to changes in climate.

“Plants provide a wonderful context for understanding changes to the environment and they certainly respond to changes in temperature and precipitation, things that climate scientists are very interested in.”

Scientists can’t be in everyone’s backyard. That’s where volunteers come in. Last year some five thousand people across the country reported their observations to Project Budburst. That information now is the foundation for an online database that includes everything from dandelions to ponderosa pines.

So after walking through our neighborhood and seeing a lot of trees that have already flowered, I’ve decided that these lilac trees outside of our house are perfect for watching because they haven’t flowered yet and there are leaf buds all over the branches. And here’s a branch and the leaf buds are huge and they are just starting to unfurl.

Now that I’ve found my lilac tree to watch, I can report today’s findings.

Really that’s it. Scientists are finding out a lot of interesting things. For example, forsythia in Chicago are blooming a week earlier. These simple observations will eventually create a snapshot of how climate change is affecting plants across the U.S.

Science Funding in a Tanking Economy (Part One)

The recession is hitting more than banks and homes these days. State budget cuts and no increases from the federal government are straining research labs and scientists. Adam Allington reports the effects might not be as obvious or immediate as the house foreclosures and the credit crisis, the effect on science jobs and innovation might be just as bad:

The recession is hitting more than banks and homes these days. State budget cuts and no increases from the federal government are straining research labs and scientists. Adam Allington reports the effects might not be as obvious or immediate as the house foreclosures and the credit crisis, the effect on science jobs and innovation might be just as bad:

At first glance there’s not much in Dale Dorsett’s lab beyond the usual – you know, grad students in white lab coats, centrifuges, test tubes.

Even though his lab is relatively small, his costs are not.

He takes me toward a locked room in the back of the lab containing a single microscope.

“It’s a laser scanning confocal microscope, which is essential for part of our work. That cost – $350,000 – now you know why we keep it locked.”

Dale is a molecular biologist at St. Louis University. He studies a genetic disorder that affects about one in ten-thousand humans.

Well, that is, when he can.

These days Dorsett says he spends more of his time filling out grant applications than he does on his research.

And he’s not the only one in this pickle. Winning grants for research is getting tough.

“The problem becomes when it gets so competitive that even really deserving projects, or very productive scientists who are doing really good work can’t get funded and that’s the situation we’re in right now.”

Funding from organizations like the National Institutes of Health and the National Science Foundation has been slipping for years. It’s a big problem.

It used to be about 30% of grant applications were successful. Now, that success rate has slipped into the teens.

And even those researchers who do get funded say grant preference is often given to projects that produce immediate results – which just isn’t the way most science works.

“I’m conservative because otherwise the lab would go under.”

Kristen Kroll runs a lab studying stem cells at Washington University.

“I would love to be more aggressive about what we go after, which connections we try to make to other models. I think I’ve curbed what we could be doing to a point where what we are doing is sustainable in the current funding climate.”

Kroll says there is such a back log of quality grant applications on file at the NIH and NSF, grant reviewers aren’t even separating wheat from chaff any more they’re separating wheat from wheat. So a lot of good research just doesn’t happen.

And in a world economy the U.S. isn’t the only player in the market for innovation. Other countries could gain an advantage in science.

James McCarter is the Chief Scientist for Divergence, a St. Louis-based biotech company.

“The emergence of India and China, in addition to Japan and Korea and Europe. There are sizeable countries out there now that are serious in these spaces and are making serious investments and have the talent.”

Now,you might be thinking, won’t that big stimulus package send wave of cash into the coffers of government research agencies – problem solved right?

Not so much. While a billion dollar shot in arm might be welcome news for some labs, many advisors worry that the long-term effect might actually exacerbate the funding crisis.

John Russell is the Associate Dean for Graduate Studies at Washington University. He says, a big pile of cash all at once does nothing for ongoing research that can take years to complete.

“One of the concerns about a big bubble is that if it’s just a bubble is that it takes five years to train somebody so it needs to be more spread out I think to be effective.”

Russell warns universities considering a building and spending spree to plan carefully, so current projects don’t reach beyond future budget realities.

Stimulus Package to Boost Research?

The government’s stimulus package is pouring billions of dollars into research for health, energy, and basic science. Rebecca Williams reports the new money will be helpful, but it’s not clear whether it’ll last:

There’s 10 billion dollars for health care research, 3 billion for other science funding, and that’s just the beginning.

Sam Rankin says it’s a positive change. He chairs the Coalition for National Science Funding.

“This administration and the current Speaker of the House have been very adamant about how important science is and that they want to fund science because they realize it’s an economic driver.”

There’s a catch. The stimulus money is a one-time thing.

But this week, President Barack Obama indicated his budget will mean steady money for health care and energy technology.

“We will invest 15 billion dollars a year to develop technologies like wind power and solar power, advanced biofuels, clean coal, and more efficient cars and trucks built right here in America.”

That makes scientists hopeful, but we won’t know the details of the budget until sometime in April.

Science Jobs Scarce (Part Two)

It’s the best of times and the worst of times to start a science career in the
United States. Researchers today have access to tools and techniques that
have accelerated the pace of discovery to new highs. But as record numbers

ready to absorb them. Adam Allington traces the supply and demand for

It’s the best of times and the worst of times to start a science career in the
United States. Researchers today have access to tools and techniques that
have accelerated the pace of discovery to new highs. But as record numbers
of PhD’s graduate, many young scientists are finding a job market that is not
ready to absorb them. Adam Allington traces the supply and demand for
young scientists in a faltering economy:

Briana Gross is in her second year of a post-doctoral fellowship at
Washington University, she’s studying genetic adaptations of wild rice.

She’s been applying for college faculty jobs for the past two years. This
year she says she’s gone all-out.

“I’ve applied for I think 36-38 jobs, 3-4 of those positions have been cancelled
completely due to hiring freezes. I’ve had two interviews.”

These days there’s a glut of qualified talent. Between too many doctoral
grads and cutbacks, it’s tough to find a position.

One recent job interview did little to bolster Gross’s confidence for the
future.

“While I was waiting to meet with the dean, one of the financial administrators came buy
and kind of joked about how I couldn’t possibly be interviewing for a position because
there was no money available to hire anyone at the university. So, if that’s happening
this year, next year is going to be really rough.”

So, how’d we end up with too many scientists for the jobs out there? Well,
the answer goes back to an event scientists simply call “the doubling.”

In 1998, President Clinton doubled budget for the National Institutes of
Health, which had the effect of drawing in all kinds of new talent and
investment for science and research.

The problem came later when that funding went flat – precisely at the same
time all those new PhD’s were entering the job market.

“You know, its like you push a bunch of people into the pipeline and then there’s been
chocking off of the U.S. pipeline.”

Kristen Kroll is a professor of developmental biology at Washington
University; she employs two post-docs in her lab.

“What we’ve done is we’ve convinced a whole generation of U.S. post-docs and graduate
students not to go into academic science.”

Young PhD’s see the uphill battle for jobs and scarce grant money and
wonder if its worth the struggle.

And it’s not just post-docs who are feeling the pressure these days—junior
faculty are spending more of their time in the lecture hall and less time in the
lab.

David Duvernell teaches biology at Southern Illinois University at
Edwardsville.

“We try to maintain an active research program at SIUE, at the same time we’re teaching
our 2 or 3 courses a semester.”

Duvernell says SIUE enrollment in freshman-level biology courses has
nearly doubled, but state support has not.

“And where the students are losing out is that then we have less time to spend in research
labs, where we train students individually and give them an experience that will
ultimately make them employable and competitive for graduate and professional
programs.”

University administrators point that historically only about 30% of all post-
docs land a faculty job, with the rest going into the private sector. Except
these the private sector is shedding jobs even faster than the universities.

Jared Strasburg is a 4th-year post-doc from Indiana University. He says if he
hasn’t found a faculty job by August, he’ll have to consider something else.

“Academia is long hours, it’s a lot of work, But, I never felt like if I put in those hours
and worked really hard that I wouldn’t be capable of getting a position and getting
funding necessary to do the work that I was interested in. Needless to say now that
proposition looks a lot more tenuous.”

In recent years some universities have taken steps to curb the number of
graduating PhD’s.

But as the number of unemployed post-graduates rises, some say the whole
system for training scientists needs to be updated to jive with the modern
economy.

As fewer and fewer scientists actually work in universities, some say more
focus needs to be placed on careers outside of academia.

Making the shift from fossil fuels to cleaner energy will be a long-term, expensive effort. But, there is the opportunity for jobs, energy independence and reducing the greenhouse gases that cause climate change. This week a report from the Brookings Institution proposes a way to help get us there: Energy Discovery-Innovation Institutes. These institutes would take a big picture view of the change and help researchers and businesses avoid pitfalls and false starts along the way. Lester Graham spoke with a supporter of the idea, Gary Was. He’s the Director the Phoenix Energy Institute at the University of Michigan:

Gary Was: Energy is a very complex topic. It’s a social issue as much as it is a
technological issue. In addition to the technological challenges of coming up with
new energy sources and proving energy efficiency, we also have a lot of social issues
involved as well. The business sector is heavily involved. Economics is a big issue.
Social behavior and social preferences are big factors in our energy use patterns and
our habits.

Lester Graham: Give me an example of that.

Was: Well, one example is plug-in hybrid electrics. There’s a lot of questions to
how these plug-in hybrids are going to function, and whether they’ll be successful. A
lot of that depends upon people’s preferences. The idea of plugging in, when you
can plug in, how long you have to plug in, how complicated or how difficult it is –
can make a big difference. We’ve seen examples of that with diesel. In Europe, half
the cars are diesel powered. We have the same technology here. There are no diesel
powered cars here. It’s a social issue, not a technological issue.

Graham: Steven Chu, the new Energy Secretary, has spent a good deal of his career
in research. What do you expect his reaction will be to your suggestion of tying
together this energy research?

Was: I think it will be quite positive. Dr. Chu has a background both in the
academic setting as well as in the National Laboratories, and I think he appreciates
well the capabilities of each institution. The meat of this whole proposal, and of this
whole concept, is that the National Laboratories alone, or universities alone, or
industry alone – the three principal research institutions in the US – really aren’t
prepared to handle a challenge of this breadth, and depth, and complexity. And that
we need a new paradigm. We need a new way to be able to take basic science,
accelerate it into development, and push it through technology, transfer it to the
private sector. None of these institutions alone can do that really highly successfully.

Graham: What is this going to do require? Is this government money to get this
launched? Is this going to be another scientific layer of bureaucracy when we get
finished? How do you handle this to make sure it’s effective?

Was: One of the problems we have with energy in the country is that, overall,
regardless of these institutes, this institute concept, its terribly underfunded – in terms
of its comparison to the impact on the economy. The energy business is a 1.5 trillion
dollar business in the US. It’s comparable to healthcare. In healthcare, there is
approximately ten times the amount of federal funds going into research than there is
in energy. So in comparison to the impacts on our lives, it’s underfunded by almost
a factor of ten.

Graham: If we’re to invest in these kinds of institutes, and invest in more research
into energy and how we use it, what kind of return might we see on our tax dollars
that we shovel over to you guys?

Was: Well, that’s a very good question. These discovery institutes, these will be
regionally situated, and each one might be on the order of 200 million dollars a year
funding, and so the entire price tag would be maybe 5 billion dollars. So what do
you get for 5 billion dollars? We expect that the transformation will be much more
rapid, it will be with fewer false starts, and left turns, or dead ends, and it will be
much more efficient than we’re able to do right now. Right now, the system is such
that technology advancements tend to sort of diffuse through society in an uncharted
and undirected way. The objective here is to sharpen that diffusion so that we can
pull these technologies out, translate them into useful products much more quickly.

Graham: Gary Was is the director of the Phoenix Energy Institute at the University
of Michigan. Thanks for coming in.

Was: Thanks very much.

Thousands of scientists from around the world will be hob-knobbing in Chicago starting today. They’re going to be celebrating the 200th birthday of Charles Darwin and how he changed science forever. But they won’t be just celebrating –- they’ll be thinking through one of the biggest environmental problems we all face:

The group’s called the American Association for the Advancement of Science, and they’re putting on their annual meeting – one of the biggest science meet-ups in the world.
This time around there’s plenty of attention on the science of climate change.

The group doesn’t mince words on the issue.

Here’s CEO – Dr. Alan Leschner.

“The last five or more years has been a period of, frankly, denial by the US government about the need to address the problem of global change and its consequences for the world. Now , we think there’s a big opportunity, particularly with the new science appointments made by President Obama to be able to address these kinds of issues in a focused and coherent way.
Scientists there will present work on whether biofuels really help cut carbon emissions, what kind of food crops are best for the climate, and whether we’re losing fish species because global warming.”

And to headline the whole thing – former Vice President Al Gore’s dropping in later this week.

The numbers and types of songbirds
are dropping dramatically in many areas of
the country. A lot of people are trying to
get a better count on the number of birds
that are still around. Stephanie Hemphill recently went with researchers
on one of the more ambitious bird count projects:

The jumping off point for this trip is a tiny airport with a grass runway in
northern Minnesota, about 20 miles from the Canadian border.

We fly for 15 minutes, over trees and swamps as far as the eye can see. Down
below we get a glimpse of a moose. And, later, a pair of rare trumpeter swans
in their nest.

The helicopter sets down in what’s known as a floating bog. Its runners are
sitting in six inches of water.

We jump out in knee-high boots and rain jackets, and douse with DEET to try
to keep the mosquitoes away.

I’m following Heidi Seeland, a graduate student who seems to know her way
around a bog.

We’re in knee-deep water. Then it’s thigh-deep Pretty soon it’s waist-deep. I try
to step on a clump of sphagnum moss. But it sinks. It holds onto my boot, and
I’m sitting in water.

Heidi helps me up, and we catch up with the others.

They fan out on different points of the compass. I follow Matt Etterson. He’s an
ornithologist, a bird expert. We slog through the bog for nearly half an hour.
Etterson is aiming for a piece of higher ground, where the trees are a little
taller, better for nesting.

Suddenly he stops. He’s found the spot he was looking for. He sets his watch
for 10 minutes and pulls out a notebook.

Etterson cocks his head this way and that, jotting the names of the birds he can
hear, and the time he hears them. He doesn’t pay any attention to the mosquito
biting the back of his neck. He just listens and takes notes.

“We had a couple of hermit thrush — that’s the singing to the north of us. A
veery called a couple of times to the west of us. A Nashville warbler, and a
couple of western palm warblers, and that was about it. It was pretty quiet
otherwise,” Etterson said.

We trudge through the muck for another 20 or 30 minutes and he repeats the
process.

It’s two hours later, and the three researchers meet at the helicopter landing spot
and compare notes. They’re excited about Etterson’s veery and Nashville
warbler. The others heard a Connecticut warbler and a Lincoln’s sparrow.

They would have been really happy if they’d heard a golden-winged warbler.
It’s one of the most threatened of bird species. The number of golden-winged
warblers has declined by some 80% during the last 50 years.

Today’s trip is an experiment to see how well it works to count birds in remote
places, using a helicopter.

It’ll take five years to finish the bird count here. Then, in 10 or 20 years, they’ll
do it all over again, to see how the birds are faring.

There’s a lot of confusion about global
warming. Is it real or not? Are the ingredients

use all safe? Even if they’re not, there’s a

Your Health.’ Lester Graham talked with Michaels,
who says companies today base their approach on the
tactics of big tobacco. The tobacco companies
successfully obscured the connections between
smoking and lung cancer for decades.

David Michaels: “Companies know that by putting off the scientific debate for as many years as
they can, they can keep doing the work that they’re doing and not be disturbed. It works.”

Lester Graham: “We hear about Bisphenol-A in plastics, of course we hear about mercury in fish,
phthalates, even something like dioxin – industry scientists say ‘we’re safe, these are in minute
quantities’ or ‘the jury is out on just how dangerous this chemical is’. If they are dangerous, why
doesn’t the government make that determination and phase these products out?”

Michaels: “Well, right now, the Bush administration has absolutely abdicated its responsibility to
protect the public’s health and the environment. It’s not even a question of phasing them out, the
Bush administration has turned a blind eye, and said ‘we’re not even going to think about those
chemicals’. I’m hoping that as public consciousness of this increases, we’ll have more demand on
regulatory agencies to do something.”

Graham: “You’re very critical of the Bush administration in the book, saying scientific review
boards are stacked with industry officials. Why, or how, does the scientific community continue to
allow that?”

Michaels: “Well, the scientific community doesn’t have the power to stop it. But the scientific
community has me furious about this. And over and over again, not just individual scientists, but
mainstream science organizations, like the American Association for the Advancement of Science,
have issued statements, have passed resolutions complaining, criticizing the Bush administration.
But that’s all we can do. Congress has to stop it. And, the American public has to stop it.”

Graham: “The members of the Bush administration often point out, ‘hey we can’t make knee-jerk
reactions, over some single study, or even a small group of studies, we really need to rely on
sound science, this needs more review’. And it sounds like common sense to many of us.”

Michaels: “Well, when I hear the Bush administration call for ‘sound science’, I see what they’re
doing is calling for something that sounds like science, but isn’t. Bisphenol-A is a great example.
There are well over 100 studies showing that this causes endocrine disorders and reproductive
disorders in laboratory animals. And there are less than a dozen studies that say it doesn’t cause
it. The question we have to ask is: should we be exposing our babies, our children, ourselves to
potentially toxic chemicals that we don’t know that they’re safe?”

Graham: “And Bisphenol-A is, of course, used in plastics, in liners of canned foods, and so forth.
It’s a product that we come across a lot.”

Michaels: “Not only that, the studies are right now that 90% of us have Bisphenol-A in our body.
We can tell that from studies where we’re are excreting it in our urine. So, it’s out there are we’re
being exposed to it. We don’t know what the effects are, but since it causes harm in animals, why
should we be exposing ourselves to it?”

Graham: “You note that journalists are often the victims of their own determination to get both
sides of the story. What are you suggesting? That journalists ignore industry when it questions
studies or scientific method? That would assume that corporations are always bad actors.”

Michaels: “No, but I think it’s very important to note, for example, when an industry scientist
criticizing the study, to note, for example, that, you know, that this criticism is being paid for by the
industry. But the other criticisms, which are, you know, are independent, often paid for by the
government through grants to universities, are independent, and therefore have a lot more validity.
We have example after example, in the book, and all through the medical literature, of companies
that essentially create studies that provide the results they want. In my reviewing it, I’ve never
found a study which disagrees with what the sponsor wanted them to hear. It’s just overwhelming.”
