"Flawed Statistics in Murder Trial May Cost Expert His Medical License," by Eliot Marshall. Science, 22 July 2005, page 543. The concept of the independence of two events is a central tenet in many statistics classes, and a British doctor may soon lose his license due to his misapplication of this principle. In the 1999 trial of a woman accused of killing her infant son, child abuse expert Roy Meadow presented an inaccurately small probability that two infants in the same family will die suddenly of unexplained natural causes. Meadow derived the statistic himself using the death probability of a single infant, but he incorrectly assumed that two interfamilial infant deaths would be independent of one another. The woman was convicted and spent three years in prison before the decision was reversed. While some fault Meadow for abusing his position as a doctor and delivering evidence outside his field of expertise, others think his current role in the case is simply that of a scapegoat.

"Harvard Researchers Discuss Systems Biology," by John Russell. BioIT World, 21 July 2005. BioIT World experiments with posting an entire interview with two scientists to follow up on a shorter report. The topic is the efforts by Harvard Medical School researchers Jeremy Gunawardena and Aneil Mallavarapu to create a new modeling language for systems biology. Gunawardena, a "selfprofessed mathematician (Ph.D. in algebraic topology)," is director of The Virtual Cell Program in the School's Department of Systems Biology, and in the interview he explains that they are "focusing on biochemical modeling, and we're using it to build fairly simple models called ODE (ordinary differential equations). You represent species as concentration or the amount of species as variables. We want to expand and use the language to describe other types of models like partial differential equations, and we're working on what it will take to write stochastic models. Right now we're just doing biochemistry, but there's nothing in the language that limits it to that."  Annette Emerson
"U math institute bugs its way to record grant," by Mary Jane Smetanka. Star Tribune, 20 July 2005. The occasion for this article is the awarding by the National Science Foundation (NSF) of a nearly $20million grant to the Institute for Mathematics and its Applications (IMA) at the University of Minnesota. The renewal grant constitutes a 77 percent increase in NSF funding for the IMA. The IMA is one of six USbased mathematics research institutes funded by the NSF; the foundation also contributes funding to a math institute in Canada. The IMA specializes in bringing together mathematicians with researchers from other areas of science and engineering and also with people from industry. Throughout its 25year history, the IMA has shown how mathematics can make substantial contributions towards the solution of practical problems in science, engineering, and technology. The article discusses an IMA "success story" in which mathematicians, biologists, and engineers began a collaboration that has led to the development of a sixlegged robot whose gait is based on that of insects. The hope is that such robots might be able to assist on, for example, future space missions. In other media coverage, IMA director Douglas Arnold was interviewed on Minnesota Public Radio's "All Things Considered" program on 21 July 2005.  Allyn Jackson
"The professor's days are numbered," by Keith O'Brien. The Boston Globe, 18 July 2005. O'Brien writes about Dan Rockmore, professor of mathematics at Dartmouth College. Some of the article is about Rockmore's teaching: He tries to keep math interesting and he says "I think it's a tragedy when people get turned off by mathematics or quantitative kinds of approaches very early in life," and part deals with numbers, especially prime numbers. Rockmore has written a recently published book Stalking the Riemann Hypothesis: The Quest to Find the Hidden Law of Prime Numbers.  Mike Breen
"Geheimnisse, die sich in Zahlen verbergen", by George Szpiro. Neue Zürcher Zeitung, 17 July 2005. This installment of Szpiro's monthly column on mathematics discusses a recent article from the Ramanujan Journal. How large can the numerator of a fraction become if a selection of the fractions 1/2, 2/3 ... N/(N+1) are multiplied or divided by one another?  Allyn Jackson
"Math and Science Are a Scream for Students in a Course on RollerCoaster Design," by Jamie Schuman. The Chronicle of Higher Education, 15 July 2005, page A20.
"DataPoint: Steady strides." Random SamplesPeople, Science, 15 July 2005, page 379. This short item reports that 333 women received doctorates in mathematics in the U.S. in 200304, which is an alltime high. The number represents onethird of all U.S. math doctoratesalmost double the fraction from 25 years ago. To those who say that women aren't suited for higher mathematics, Ellen Kirkman, a mathematics professor at Wake Forest and lead author of the survey on which the article is based, says, "We would not be seeing this increase if women did not have the ability or the stamina to pursue math degrees." The survey is in the August issue of Notices.  Mike Breen
"9YearOlds Said Better in Math, Reading," by Darlene Superville. Guardian Unlimited, 14 July 2005. The performance on a 2004 national math test improved for many age groups and for minorities. Nineyear olds scored 241 in mathematics (out of 500) compared to 232 in 1999. Nine and thirteenyear old minority students earned their highest marks in the history of the exam. The test, given by the National Assessment of Educational Progress, is voluntary. It was taken by 28,000 students during the 200304 school year.  Mike Breen

"Take it to the limit," by Dana Mackenzie. New Scientist, 9 July 2005. This article discusses a revolution that has taken place in the science and engineering of communication codes. These codes "have nothing to do with spies or security," the article explains. Rather, the codes are used to ensure efficient and reliable transmission of information over communication channels; communication between spacecraft and the Earth is cited as a prime area where such codes play a vital role. Communication channels always have some amount of noise, which causes errors in the information transmitted. There are ways of correcting these errors, but they add to the cost of the transmission. In the 1940s, Claude Shannon developed a notion that is now known as the "Shannon limit", which, as the article describes it, is "a formula for how much information you can send with essentially perfect fidelity at a given signaltonoise ratio." The problem was, Shannon's work gave no indication of how to create codes that give results close to the Shannon limit. For decades engineers struggled along with codes that gave far less than optimal results. It was only in the 1990s that some littleknown research was rediscovered that allowed the creation of new codes, called turbo codes and lowdensity parity check (LDPC) codes, which operate essentially at the Shannon limit.

"Teaching Qubits New Tricks," by Charles Seife. Science, 8 July 2005, page 238. Quantum computers would revolutionize computing: For example they could quickly factor the large numbers that current encryption methods are based on. A trait they share with traditional computers is the need for error correction. Physicist Ray Laflamme and colleagues have shown mathematically that quantum error correction techniques that had appeared to be different are actually the same. This could make quantum error correction more efficient and help people understand the limits of quantum information. Peter Shor said that the result is very nice but, "Whether it's a giant leap or just a substantial step forward remains to be seen." The research is published in the Physical Review Letters.

"A Book With a Theory of Everything?," by John Allen Paulos. ABC News, 3 July 2005. Paulos reviews a new book, The Road to Reality: A Complete Guide to the Laws of the Universe, by Roger Penrose. He describes the 1,100page, detailpacked tome as more like a mathematical physics text than a book of popular science, as the author focuses "on the facts and theories of modern physics and the mathematical techniques needed to arrive at them" in the attempt to explain the laws governing our universe. In the end Paulos describes the book as "truly magisterial" but one which will be best appreciated by those who have considerable background in the subjects.  Annette Emerson

"Gender Divide: Educators worrying more than in the past about shortage of women in such hardscience fields as engineering," by Laura Giovanelli. WinstonSalem Journal, 3 July 2005. "Summer camps geared toward girls have been set up all over North Carolina and the country as educators work to attract more women to engineering and other mathrelated fields," this article reports. One of these camps is the setting for the article, which discusses the phenomenon of low representation of women in mathematics and science. One of the teachers in the camp noted that even when girls display mathematical ability, they often lack confidence in that ability. "Even at 12, some girls have already decided what they're not good at," the article says. The camps are dedicated to building up girls' confidence in mathematics so that they continue to study the subject throughout high school and beyond.  Allyn Jackson
"Renaissance's Man: James Simons Does The Math on Fund," by Gregory Zuckerman. Wall Street Journal, 1 July 2005, page C1; "Mr. Simons, a worldclass mathematician who runs Renaissance Technologies Corp., is creating a buzz in the hedgefund world because he is about to launch a fund that he claims could handle US$100 billionabout 10 percent of all assets managed by hedge funds today. It will have a minimum investment of US$20 million, and is aimed at institutional investors, according to early marketing materials," writes Zuckerman. The article discusses Simons' wildly successful company, which he built after an outstanding but brief career as a mathematician. Together with mathematician SS Chern, Simons developed the socalled ChernSimons invariants, which have been important in theoretical physics. For his work in geometry Simons received the AMS Veblen Prize in 1976. He taught at MIT, Harvard, and SUNY Stony Brook and also served as a codebreaker during the Vietnam War before switching to money management. Simons' company closely guards the secrets to his success. Of the new hedge fund, Zuckerman writes: "The fund will use complex quantitative models, developed by the 60 or so mathematics and physics Ph.D.s on staff". Although Simons rarely talks with reporters, he did talk with Joseph Nocera for the IHT article (which originally ran in the New York Times.  Allyn Jackson
"What Don't We Know?" Science, 1 July 2005, pages 75102. In celebration of its 125th year of publication, Science has published 125 unanswered scientific questions. Included in the questions are the seven Millennium Problems (the solution of each earns the solver one million dollars). Charles Seife writes about the P = NP? problem on page 96 in "What Are the Limits of Conventional Computing?". The other six problems are listed at the bottom of pages 101 and 102. There is an error in the description of the Riemann Hypothesis, however.  Mike Breen

"Tilt! If Highrise Buildings Were Designed More Like Ships, Would They Float Upright During An Earthquake?," by Dana Mackenzie. Discover, July 2005, pages 3637. If an earthquake causes the ground to behave like a fluid, could "buoyant" buildings survive the melee without capsizing like a ship in a storm? Using computer models of floatation principles spelled out by Archimedes in the third century, mathematician Chris Rorres is developing answers to this question. By testing the angle at which different shapes will tilt in liquid, Rorres obtained a measure that can predict whether an object will collapse following an earthquake. Other scientists point out that Rorres' model may not be directly applicable: Postearthquake soil may not act like a true liquid and constructing buildings according to the requisite ratio may present other risks. Still, Rorres' work represents a promising idea in preventing earthquake destruction.  Lisa DeKeukelaere
