Alumni Dr. George Thurston '73 will present on Asthma and Diesel Air Pollution

Diesel Air Pollution and
Asthma in New York City

Presented by
Dr. George D. Thurston '73
Dept. of Environmental Medicine
NYU School of Medicine
Nelson Institute of
Environmental Medicine

Friday, October 2, 2009
12:00 PM
Barus & Holley
Room 190
Brown University
182 Hope Street
Providence, RI

Presented by the Superfund Research Program - www.brown.edu/sbrp

Childhood asthma is at near epidemic proportions in parts of New York City, affecting as many as one quarter of all elementary aged children in certain under-served minority neighborhoods of the city. There is also an increasing body of evidence indicating that living near to traffic is associated with increased respiratory problems in children. Exposure to fine particles from diesel vehicles is suspected as a likely causal agent in these associations between traffic and asthma, but there is only limited information relating personal exposures to diesel particles and health for individual children. This seminar introduces both the asthma problem in New York City and the recent evidence regarding asthma and diesel air pollution, and then presents recent in-press results of a study conducted by NYU in the South Bronx that has directly tested the relationship between childhood asthma symptoms and personal exposures to diesel particles. Options available to control diesel emissions in New York City and elsewhere are also discussed.

Professor Allan Bower publishes new book, Applied Mechanics of Solids


Professor Allan Bowers new book, Applied Mechanics of Solids, comes out today, October 1, 2009.

Applied Mechanics of Solids summarizes the physical laws, mathematical methods, and computer algorithms that are used to predict the response of materials and structures to mechanical or thermal loading.

Topics include: the mathematical descriptions of deformation and forces in solids; constitutive laws; analytical techniques and solutions to linear elastic and elastic-plastic boundary value problems; the use and theory of finite element analysis; fracture mechanics; and the theory of deformable rods, plates and shells.

Over 400 practice problems are provided on a companion web site, as well as demonstration finite element codes in MAPLE and MATLAB. The text is intended for advanced undergraduate or graduate students, as well as practicing engineers and scientists. It will be particularly useful to readers who wish to learn enough about solid mechanics to impress their teachers, colleagues, research advisors, or managers, but who would prefer not to study the subject in depth.

An electronic version of the text can be accessed at http://solidmechanics.org and its also available from Amazon.

Audio Insights: Nanovis developing nanosurface technology


Listen to audio excerpts from a recent highlight interview with Professor Thomas Webster talking about his start-up company Nanovis.

Nanovis' leaders say, depending on the type of conventional implant, up to five percent can become problematic because the body rejects it, recognizing it as a foreign object because its smooth surface doesn't match the rough surface features of human tissue. However, the nanosurfaced implants Nanovis is developing feature a "roughness" that mimics human tissue, allowing the body to "accept" them. Webster says the nanosurfaced implants decrease infection, reduce the growth of scar tissue and promote the growth of healthy tissue. Listen

Using the same core idea of mimicking the natural roughness of human tissue, Nanovis is developing nanosurface technology for orthopedic, spinal, dental, cardiovascular and soft tissue implants. Listen

"It's a pretty exciting time for me as a researcher and a pretty exciting time for this mysterious sounding field of nanotechnology. There's actually real world application for this field—not just the nano iPod!" laughs Webster. "There are actual medical devices and real clinical treatments that can benefit from nanotechnology."

Testing nanomaterials for safety

"Scientists are preemptively testing the potentially ill effects of the tiny molecules and even atoms engineered at the scale of one billionth of a meter or smaller."

Carbon nanoparticles appear to be benign when fed to fruit fly larvae, but adults exposed to the nanoparticles in powdery form are not as lucky. Research led by David Rand and Robert Hurt show two varieties of carbon nanoparticles stuck to the flies, impeded them from climbing and ultimately caused them to die.

Tissue engineering research at Brown

Codirector of Brown University’s Center for Biomedical Engineering, Jeff Morgan leads a team of scientists who have developed novel ways of forming individual cells into living tissue. Some day, their techniques, in combination with stem-cell technology, could cure or lessen the suffering of diabetes and other debilitating diseases.

Strictly speaking, Morgan is a tissue engineer –– one of a substantial number of scientists around the world who are learning how to create groupings of cells that mimic the function of tissues or organs. Formed in the laboratory, these tissues can be transplanted into living creatures. Research is still largely confined to experimental animals –– but success so far in mice and rats holds great promise for humans.

Morgan’s advance is his unique method of growing and assembling individual cells into larger clusters –– what he calls the potential “building blocks” of tissues and organs that could be produced on demand.

Alumni develop sleep analyzer

In 2003, three Brown University undergraduates, Eric Shashoua, Ben Rubin and Jason Donahue, sat in a school cafeteria and mused about their grogginess after an all-night study session. They knew that the stress of exams played a role, but they started wondering about the science of their exhaustion.

Little did they imagine that their discussion would eventually lead to the founding of Zeo, maker of the first direct-to-consumer sleep device that analyzes nighttime sleep patterns. Zeo's product, the Personal Sleep Coach, uses a soft headband loaded with sensors to monitor brain waves. The data are sent wirelessly to a small device on a nightstand; from there they can be uploaded to the MyZeo.com Web site. MyZeo.com then analyzes the data and e-mails back a strategy and suggestions for improving the next night's sleep.

However, once these three would-be entrepreneurs decided to create a science-based aid for the estimated 70 million Americans suffering from chronic sleep disorders, they realized they were lacking a key ingredient: an investor--or several--to fund their research and development.

Initial fundraising began in the cafeterias at Brown. "We literally went table-to-table to talk about our innovation and get people interested in contributing," Shashoua recalls. Those discussions led to introductions to wealthy Brown alumni, experts in sleep research and so-called "angel investors."

Indo-US Science and Technology Forum collaborates with Brown


Created in March 2000, the Indo-US Science and Technology Forum (IUSSTF), established under an agreement between the Governments of India and the United States of America functions to synthesize collaborative research and promote substantive interaction among government, academia and industry. The overall goal of IUSSTF is “to provide opportunities, to exchange ideas, information, skills and technologies, and to collaborate on scientific and technological endeavours of mutual interest that can translate the power of science for the benefit of mankind at large.” (http://indousstf.org/

This Forum has a specific biomaterials area in which Brown University and Indian Institute Technology (ITT) Kanpur (along with other affiliated schools and companies) had a competitive proposal accepted in November 2008.  Co-Coordinator Bikramjit Basu of ITT Kanpur most recent visit in Phase I of this project was to fellow coordinator Thomas Webster at Brown University.  This July 2009 visit included many collaborative meetings and a talk on the biomaterials research in Dr. Basu’s lab.  The goals of these types of visits are to facilitate collaboration and increase their outreach potential.  A core deliverable of the project is to “train the next generation of scientists in the international interdisciplinary arena.” (http://www.iitk.ac.in/indo_us_biomaterials/)  

Dr. Basu explains, “This collaboration depends on the two way visits between researchers in the US and India.”  It is clear that these visits help researchers develop concrete projects. The dialogue between the different institutions and researchers allows for sharing of research results and a better understanding of the challenges faced by each group.  The biomaterials area specifically faces the unique challenge of bridging the gap between traditional biology and materials engineering.  The next steps for this project include working to integrate more industrial partners and medical professionals into the research collaborations.

Breuer collaborates on bat research

An excerpt from a recent Forbes article:
Researchers at Brown University are three years into another Air Force grant, this a five-year, $6 million grant shared among five other universities, to understand perhaps the most impressive fliers of all--bats.

Unlike insects and birds, bats have long thin fingers that reach through their wings, and their wings are made out of an extraordinarily stretchy membrane. This allows them to twist and shape their wings in ways that other creatures can't, and so maneuver quickly and accurately through tight spaces like caves. They can take off almost vertically from the ground and they can take off hanging upside down.

"Nature does many, many things we don't know how to do in engineering," laments Kenneth Breuer, an engineering professor at Brown and the principal investigator on the Air Force grant.

Breuer and his Brown colleague Sharon Swartz, an evolutionary biologist, put bats in wind tunnels and study how they move their wings during takeoff, flight and landing. Using lasers that illuminate tiny particles in the air flow created by the bats' wings, the researchers study the turbulence created.

Bat research highlighted in Forbes on June 26, 2009.

Nanoparticles eliminate bacterial infection on prosthetic

Infected implants now have a foe. Brown University researchers have created a nanoparticle that can penetrate a bacterial-produced film on prosthetics and kill the bacteria. The finding, published in the International Journal of Nanomedicine, is the first time that iron-oxide nanoparticles have been shown to eliminate a bacterial infection on an implanted prosthetic device.

Hydrodynamics of Microorganisms

Professor Powers' article, Hydrodynamics of Swimming Mircoorganisms, was accepted this week in Reports on Progress in Physics.
Preview the article here: http://dl.getdropbox.com/u/652169/reviseLaugaPowersv3.pdf
Abstract.
Cell motility in viscous fluids is ubiquitous and affects many biological processes, including reproduction, infection, and the marine life ecosystem. Here we review the biophysical and mechanical principles of locomotion at the small scales relevant to cell swimming, tens of microns and below. At this scale, inertia is unimportant and the Reynolds number is small. Our emphasis is on the simple physical picture and fundamental flow physics phenomena in this regime. We first give a brief overview of the mechanisms for swimming motility, and of the basic properties of flows at low Reynolds number, paying special attention to aspects most relevant for swimming, such as resistance matrices for solid bodies, flow singularities, and kinematic requirements for net translation. Then we review classical theoretical work on cell motility, in particular early calculations of swimming kinematics with prescribed stroke and the application of resistive-force theory and slender-body theory to flagellar locomotion. After examining the physical means by which flagella are actuated, we outline areas of active research, including hydrodynamic interactions, biological locomotion in complex fluids, the design of small-scale artificial swimmers, and the optimization of locomotion strategies.

In addition, some of his recent work was highlighted on the NSF news page:
Scientists studying how marine bacteria move have discovered that a sharp variation in water current segregates right-handed bacteria from their left-handed brethren, impelling the microbes in opposite directions. This finding and the possibility of quickly and cheaply implementing the segregation of two-handed objects in the laboratory could have a big impact on industries like the pharmaceutical industry, for which the separation of right-handed from left-handed molecules can be crucial to drug safety.
