SCIENCE AND LAW
Neuroscience in the Courts--A Revolution in Justice?
New imaging tools that show the brain in action raise the prospect that the courts might someday be able to reliably assess whether a witness has lied during pre-trial statements or whether a candidate for probation has a propensity to violence. But if human actions ever could be explained by a close analysis of the firing of neurons, would a criminal defendant then be able to claim that he is not really guilty but simply the victim of a "broken brain"?
Barbara Jacobs Rothstein and David Heeger.
That is the sort of question judges and lawyers may have to grapple with in the courtroom in the future--and at a seminar organized by AAAS, 16 state and federal judges got an intriguing preview of the emerging issues. The seminar, held 29 to 30 June at the Dana Center in Washington, D.C., was co-sponsored by the Federal Judicial Center and the National Center for State Courts, with funding from the Charles A. Dana Foundation.
Experts told the judges about brain-scanning technologies such as functional magnetic resonance imaging (fMRI) and positron emission tomography (PET). They heard about the formation of memory and whether it may be possible to distinguish true memories from false ones. They also heard about the possible neurological bases for violent and antisocial behavior.
The judges broke into teams to consider several hypothetical case studies, including whether a brain scanner that proved capable of identifying a propensity to violence should be used in jail assignments for convicted felons or to help decide whether a job applicant is suitable for employment. In general, the judicial reaction was cautious, with much talk about how to define "propensity" and whether such judgments can ever be made in isolation.
There was lively discussion about fMRI, a technology that can produce real-time images of people's brains as they answer questions, listen to sounds, view images, and respond to other stimuli. Some studies have shown that several regions of the brain, including the anterior cingulate cortex, appear to be active when a person is lying. Two private companies already are marketing fMRI "lie detection" services to police departments and U.S. government agencies, including the Department of Defense, the Department of Justice, the National Security Agency, and the CIA.
But David Heeger, a professor of psychology and neural science at New York University, cautioned the judges that fMRI is not a suitable lie detector now and may never fill the bill, even though it has the potential to outperform the traditional polygraph. In key studies, research subjects were instructed to lie and tested in settings where they knew there would be no serious consequences for lying. Moreover, the anterior cingulate cortex and other brain areas implicated in lying appear to play roles in a wide range of cognitive functions. So it is difficult to draw a specific link between activity in these brain regions and lying, critics say.
Such issues are of more than academic interest to the judges. Under the U.S. Supreme Court's Daubert ruling in 1993 and two subsequent rulings, trial judges have a gatekeeping responsibility in determining the validity of scientific evidence and all expert testimony.
"We judges are often at a point where we have to make very important decisions at the cutting edge of the juxtaposition of law and science," said Barbara Jacobs Rothstein, director of the Federal Judicial Center and a federal judge for the Western District of Washington state.
As science gains a better understanding of the physical basis in the brain for certain behaviors, some specialists argue that concepts such as free will, competency, and legal responsibility may be open to challenge. Against that backdrop, they say, it is important that judges be educated and informed about the scientific status of such neuroscience methods as imaging studies.
"I think law generally is behind the curve of science," said Stephen Spindler, a state judge in Indiana. "We don't get to deal with these things until someone springs them upon us. Law is reactive, not proactive, and we're getting a preview of what we can expect, maybe not tomorrow or next year, but coming down the pike."
The judicial seminar continues the effort by AAAS to bring together specialists from diverse fields to talk about the implications of neuroscience. Mark S. Frankel, the head of AAAS's Scientific Freedom, Responsibility and Law Program, said another neuroscience seminar for judges will be held 7 to 8 December at Stanford University in California.

Science, AAAS Assess “State of the Planet”
The ability to address the critical environmental issues of our time--such as climate change, the health of Earth's oceans, and sustainability--is often checked by uncertainty and misunderstanding among policy-makers and the public. Now Science and AAAS have published a new volume that is designed to provide a state-of-the-art assessment of the complex, interrelated challenges that will shape our environmental future.
"Science Magazine's State of the Planet 2006–2007" [Island Press, June 2006, 201 pp.; $16.95 soft/$32 hard; ISBN: 1597260630] provides a clear, accessible view of scientific consensus on the environmental threats confronting Earth. The new volume includes three dozen essays and news stories, written by some of the world's most respected researchers, policy experts, and science journalists.
"Science Magazine's State of the Planet 2006–2007"
In the book's introduction, Science Editor-in-Chief Donald Kennedy notes that resources essential to life on Earth are closely connected to the health of the environment. The quality of fresh water depends on the condition of watershed forests. Agriculture depends on the vitality of surrounding ecosystems that are home to bees and birds. Climate change affects the distribution of plants and animals in the wild.
"To the editors of Science, these relationships--and the changes in them as humans continue to alter the world--comprise the most important and challenging issues societies face," Kennedy writes. "Without scientific understanding, those who will make policies in the future will be forced to do so without the most essential tool they could have."
The new book is a compilation of articles previously published in Science and recently updated, plus three new summary essays by Kennedy. The articles were chosen and assembled by editors at the journal.
At the heart of the book is a landmark 1968 essay in Science, "The Tragedy of the Commons," by the late Garrett Hardin, formerly a professor of human ecology at the University of California at Santa Barbara. ("The Commons" is a term that describes the environment shared by all of life, and on which all of life depends.) Other essays in the new book originally were published in Science in November and December 2003 as part of a series called "The State of the Planet."
The new book features an international roster of top environmental scholars. One of the essays, "The Struggle to Govern the Commons," won the 2005 Sustainability Science Award from the Ecological Society of America. It was written by Thomas Dietz, director of the Environmental Science and Policy Program at Michigan State University; Elinor Ostrom, co-director of the Center for the Study of Institutions, Population and Environmental Change at Indiana University; and Paul C. Stern at the Division of Social and Behavioral Sciences and Education at the U.S. National Academies in Washington, D.C.
Among the other contributors:
- Martin Jenkins from the World Conservation Monitoring Centre of the United Nations Environment Programme in Cambridge, U.K., writing on the prospects for biodiversity. Jenkins is co-author of the "World Atlas of Biodiversity";
- Hajime Akimoto, director of the Atmospheric Composition Research Program at the Frontier Research Center for Global Change in Yokohama, Japan, writing on global air quality;
- Robert T. Watson, chief scientist and director for Environmentally and Socially Sustainable Development at the World Bank, writing on climate change and the Kyoto Protocol; and
- Joel E. Cohen, an award-winning researcher, prolific author and head of the Laboratory of Populations at Rockefeller University and Columbia University in New York, writing on population.

AAAS Testifies on Stem Cell Research
AAAS CEO Alan I. Leshner recommended to a U.S. Senate panel that federally funded science should explore the broadest possible range of stem cell research, including techniques that require the use of early-stage human embryos.
Leshner, the executive publisher of Science, was among those who testified on a bill co-sponsored by U.S. Senators Rick Santorum and Arlen Specter, both Pennsylvania Republicans, to promote stem cell research that does not require the use of human embryos.
Such research is important, Leshner told a subcommittee of the Appropriations Committee on 27 June. But, he added, the most promising avenues to date appear to be derivation of stem cells from early-stage embryos at in vitro fertilization (IVF) clinics or created by somatic cell nuclear transfer. "The alternatives that are now being developed are, in fact, intriguing," Leshner said, "but we really don't know what their ultimate utility will be, and each has potential problems or complications."
Specter said he backs research on alternative stem cell methods, while continuing to push for a vote on legislation he has co-sponsored with Senator Tom Harkin (D–IA) that would authorize federally funded research on new stem cell lines derived from the microscopic embryos left over in the IVF process. President George W. Bush issued a directive in 2001 that federal dollars could be used for research only on embryonic stem cell lines already in existence at that time.
