4Opportunity
- a renewed commitment to education in
mathematics and science American students will
move from the middle to the top of the pack in
science and math over the next decade for we know
that the nation that out-educates us today will
out-compete us tomorrow. And I don't intend to
have us out-educated. - President Barack Obama
- National Academy of Sciences 146th Annual Meeting
- Washington DC, April 27, 2009
5Opportunity and a Challenge
6- Almost a third of ordinary Americans say human
beings have existed in their current form since
the beginning of time, a view held by only 2
percent of the scientists. - Only about half of the public agrees that people
are behind climate change, and 11 percent does
not believe there is any warming at all.
7- According to the survey, about a third of
Americans think there is lively scientific debate
on both topics in fact, there is no credible
scientific challenge to the theory of evolution
and there is little doubt that human activity is
altering the chemistry of the atmosphere in ways
that threaten global climate.

9The Arc of Biology 19th 20th Centuries
- In the early 20th century biology emerged from
natural history and physiology around the
question What is life? - Biologist Jacques Loeb (1859-1924) helped to
shape modern biological research through his
emphasis on reductionism, experiments, and the
engineering ideal.
10The Arc of Biology Understanding and
Controlling Life
- RNA Interference (RNAi) - An ancient evolutionary
mechanism for silencing gene expression - An innate and adaptive response that protects a
cell from foreign genes by targeting invading
gene messenger RNAs
11The Arc of Biology To Improve the Quality of
Human Life
Practical application of RNAi in agricultural and
medical biotechnology
- Resistance to papaya virus
- Therapeutic RNAi macular degeneration
2006 Nobel Prize in Physiology and Medicine to
Fire and Mello
12The Arc of Biology What is Life?
- Theoretical Constructs in Biology
- All living things are made from cells, the
chemical factories of life CELL BIOLOGY - All life is based on the same genetic code
organized as DNA or RNA GENETICS - All forms of life evolved by natural selection or
genetic drift EVOLUTION - All life is connected to form ecosystems ECOLOGY

Make the United States the most attractive
setting in which to study and perform research so
that we can develop, recruit, and retain the best
and brightest students, scientists, and engineers
from within the United States and throughout the
world.
36What is Learning?
- Learning is the creative process by which new
knowledge is discovered.

38Opportunity
- This is how we will lead the world in new
discoveries in this new century. But I think all
of you understand it will take far more than the
work of government. It will take all of us. It
will take all of you. And so today I want to
challenge you to use your love and knowledge of
science to spark the same sense of wonder and
excitement in a new generation. - President Barack Obama
- National Academy of Sciences 146th Annual Meeting
- Washington DC, April 27, 2009
39- Scientists must find new ways to engage with the
public. One cannot just exhort we all agree you
should agree with us. Its a much more
interactive process thats involved. Its time
consuming and can be tedious. But its very
important. - Alan I. Leshner,
- American Association for the Advancement of
Science
40Opportunity
- I want to persuade you to spend time in the
classroom, talking and showing young people what
it is that your work can mean, and what it means
to you. - President Barack Obama
