VU Inside: Dr. William Fissell’s Artificial Kidney
Vanderbilt University Medical Center nephrologist and associate professor of medicine Dr. William H. Fissell IV, is making major progress on a first-of-its kind device to free kidney patients from dialysis. He is building an implantable artificial kidney with microchip filters and living kidney cells that will be powered by a patient’s own heart. “We are creating a bio-hybrid device that can mimic a kidney to remove enough waste products, salt and water to keep a patient off dialysis,” said Fissell. Fissell says the goal is to make it small enough, roughly the size of a soda can, to be implanted inside a patient’s body.

Neanderthal DNA has subtle but significant impact on human traits
Since 2010 scientists have known that people of Eurasian origin have inherited anywhere from 1 to 4 percent of their DNA from Neanderthals. The discovery spawned a number of hypotheses about the effects these genetic variants may have on the physical characteristics or behavior of modern humans, ranging from skin color to heightened allergies to fat metabolism...generating dozens of colorful headlines including “What your Neanderthal DNA is doing for you” and “Neanderthals are to blame for our allergies” and “Did Europeans Get Fat From Neanderthals?” Now, the first study that directly compares Neanderthal DNA in the genomes of a significant population of adults of European ancestry with their clinical records confirms that this archaic genetic legacy has a subtle but significant impact on modern human biology. “Our main finding is that Neanderthal DNA does influence clinical traits in modern humans: "We discovered associations between Neanderthal DNA and a wide range of traits, including immunological, dermatological, neurological, psychiatric and reproductive diseases,” said John Capra, senior author of the paper “The phenotypic legacy of admixture between modern humans and Neanderthals” published in the Feb. 12 issue of the journal Science. The evolutionary geneticist is an assistant professor of biological sciences at Vanderbilt University. Some of the associations that Capra and his colleagues found confirm previous hypotheses. One example is the proposal that Neanderthal DNA affects cells called keratinocytes that help protect the skin from environmental damage such as ultraviolet radiation and pathogens. The new analysis found Neanderthal DNA variants influence skin biology in modern humans, in particular the risk of developing sun-induced skin lesions called keratosis, which are caused by abnormal keratinocytes. In addition, there were a number of surprises. For example, they found that a specific bit of Neanderthal DNA significantly increases risk for nicotine addiction. They also found a number of variants that influence the risk for depression: some positively and some negatively. In fact, a surprisingly number of snippets of Neanderthal DNA were associated with psychiatric and neurological effects, the study found.

VU INSIDE:  Cotton Candy and Artificial Blood Vessels
Vanderbilt University mechanical engineer Leon Bellan is working to create artificial human capillary blood vessels using cotton candy and gelatin. His goal is for researchers to use these man-made capillaries to help keep artificial organs and other tissues alive, which could dramatically impact the field of regenerative medicine. VASCULAR TOOLBOX Bellan’s lab is hoping these artificial capillaries will be a part of what he calls a ‘vascular toolbox’ to help researchers sustain multiple types of human tissue. “If you want to build thick tissue you need this vascular network, this sort of internal plumbing to help keep the cells embedded within alive,” said Bellan. “This vascularization issue is a hurdle for lots of areas of tissue engineering, so we feel our research can have far-reaching benefits.” HOW IT WORKS Bellan’s lab focuses on the smallest blood vessels in the human body, the capillaries. His unique ‘cotton candy’ technique allows them to build channels that match this size. “Our lab basically makes unique materials based on this sacrificial cotton candy approach that we’ve developed where we embed cotton candy or cotton candy-like materials within gelatin and then remove the fibers to make an intricate 3D channel system,” said Bellan. When the gelatin is poured over the cotton candy, the materials do not blend together because Bellan figured out a way to dissolve the cotton candy on command. “When the jello has set, we change the PH and then the fibers dissolve,” said Bellan. 1/10 THE SIZE OF A HUMAN HAIR Bellan’s lab grows endothelial cells with the goal of implanting them into the artificial channels. But, like real capillaries, the artificial blood vessels are miniscule, about 1/10 the size of a human hair. This makes the next step of lining the artificial channels with real human cells extremely challenging. “We’re essentially trying to fit a 10 micron suspended cell within a 10 micron channel,” said Bellan. “What we’re trying to work out right now is how to get the cells into the channels without clogging.” NEXT STEPS The next step in the research is to see if Bellan’s artificial capillaries will be accepted by real tissue. “We need to see if we can get a real vascular network to integrate with our artificial capillary network inside these tissue-engineered constructs.” BIG PICTURE Bellan’s big picture dream is to use his artificial capillaries to help keep artificial organs alive. “Instead of having to wait for a donor for an organ, you would actually build the organ seeded with the patient’s own cells.” Though it may sound like science fiction today, Bellan says his lab is making progress. AFFORDABLE SCIENCE Bellan wants the process of researching and making artificial capillaries to be affordable. “We use gelatin not for any particular reason other than it is cheap and cells love growing on gelatin. It’s a basic, easy material to work with.” The cotton candy machines used in Bellan’s lab are essentially adapted toys. “Instead of paying thousands or millions or tens of millions of dollars for a piece of equipment, we pay $40.” Bellan says this mentality turns research into reality. “We want our research to be scalable and economically viable. Because it’s one thing to show that you can do it, it’s another thing to show that you can do it in a way that makes sense.” DR. COTTON CANDY Bellan has been surrounded by cotton candy for most of his career. So what does he really think about the pink stuff? “I think it’s actually kind of disgusting to eat, but I don’t mind being associated with cotton candy forever. Hopefully I’ll do something else that’s interesting and unique in the future as well, but I’ll take cotton candy for now.” This project was supported in part by National Institutes of Health grant R00 EB013630.

Ultrathin device harvests electricity from human motion
Imagine slipping into a jacket, shirt or skirt that powers your cell phone, fitness tracker and other personal electronic devices as you walk, wave and even when you are sitting down. A new, ultrathin energy harvesting system developed at Vanderbilt University’s Nanomaterials and Energy Devices Laboratory has the potential to do just that. Based on battery technology and made from layers of black phosphorus that are only a few atoms thick, the new device generates small amounts of electricity when it is bent or pressed even at the extremely low frequencies characteristic of human motion. “In the future, I expect that we will all become charging depots for our personal devices by pulling energy directly from our motions and the environment,” said Assistant Professor of Mechanical Engineering Cary Pint, who directed the research. The new energy harvesting system is described in a paper titled “Ultralow Frequency Electrochemical Mechanical Strain Energy Harvester using 2D Black Phosphorus Nanosheets” published XXX online by the journal ACS Energy Letters.

Biologist reaches into electric eel tank, comes out with equation to measure shocks
The shock from a young electric eel feels like accidentally touching a horse fence. A big one is more like getting tasered by nine of the devices at once. Vanderbilt University researcher Ken Catania knows because he stuck his arm into a tank with small eel 10 times because it was the only way to get accurate measurements of the circuit created by animal, arm and water. Measuring the shock from those interactions allowed him to solve an equation that he can extrapolate to measure the power released bigger eels, which can grow to 8 feet or longer. Catania, Stevenson Professor of Biological Sciences, studies the neurobiology of predators and prey and last year proved the validity of a controversial 200-year-old account of eels leaping out of Amazonian waters to shock horses. But documenting their leaping ability left him wondering about the resistances and current for each component of an attack. “It was definitely a good lesson in how efficient the electric eel would be at deterring a predator,” said Catania, who worked with a 16 inch-long juvenile eel he affectionately named Finless. “Eels are essentially batteries immersed in water, and I wanted to solve the question of how powerful those batteries are. What’s the internal resistance of the battery? What’s the resistance of the water? My past research left out the last variable: my arm.” To close the circuit and get the measurement, he created a device that used copper wire to conduct the electricity from the shock to his arm back to the water, one of the methods documented in his paper “Power Transfer to a Human during an Electric Eel’s Shocking Leap.” It will be published in the Sept. 25 issue of Current Biology. Catania said the research reminded him that there’s always something more to learn about electric eels, even though they’ve been studied for 200 years. “They’re so much more sophisticated than we possibly could have imagined,” he said. “This animal can generate hundreds of volts, but they’ve also evolved to very efficiently deliver that electricity.” Media Inquiries Heidi Hall, (615) 322-NEWS Heidi.Hall@Vanderbilt.edu Get more research news from Vanderbilt at http://vu.edu/research-news Follow Vanderbilt on Twitter: https://twitter.com/vanderbiltu, on Instagram: http://instagram.com/vanderbiltu and on Facebook: https://www.facebook.com/vanderbilt.

Tiny mechanical wrist gives new dexterity to needlescopic surgery
With the flick of a tiny mechanical wrist, a team of engineers and doctors at Vanderbilt University’s Medical Engineering and Discovery Laboratory hope to give needlescopic surgery a whole new degree of dexterity. Needlescopic surgery, which uses surgical instruments shrunk to sinvasive surgery. The needle-sized incisions it requires are so small that they can be sealed with surgical tape and usually heal without leaving a scar. A research team headed by Associate Professor of Mechanical Engineering Robert Webster has developed a surgical robot with steerable needles equipped with wrists that are less than 1/16th of an inch (2 mm) thick. The achievement is described in a paper titled “A wrist for needle-sized surgical robots” presented last month at the International Conference on Robotics and Automation in Seattle. The new device is designed to provide needlescopic tools with a degree of dexterity that they have previously lacked. Not only will this allow surgeon-operators to perform a number of procedures such as precise resections and suturing that haven’t been possible before, but it will also allow the use of needles in places that have been beyond its reach, such as the nose, throat, ears and brain. “The smaller you can make surgical instruments the better...as long as you can maintain an adequate degree of dexterity,” said Professor of Urological Surgery S. Duke Herrell who is consulting on the project. “In my experience, the smaller the instruments, the less post-operative pain patients experience and the faster they recover.” For the last six years, Webster and his colleagues have been developing a surgical robot that uses “steerable needles.” This is a system of telescoping tubes that are made out of nitinol, a “memory metal” that retains it shape. Each tube has a different intrinsic curvature. By precisely rotating, extending and retracting the tubes, an operator can steer the tip in different directions, allowing it to follow a curving path through the body. Vanderbilt University applied for a provisional patent on the design in May. Team members would like to test the system by using it for “transnasal” surgery: operations to remove tumors in the pituitary gland and at the skull base that traditionally involve cutting large openings in a patient’s skull and/or face. Studies have shown that using an endoscope to go through the nasal cavity is less traumatic, but the procedure is so difficult that only a handful of surgeons have mastered it. “It should be useful for a number of other operations as well,” said Webster. “We think once we give this tool to surgeons they will find all kinds of applications we haven’t thought of.” By the end of the summer, they hope to have completed the control software and the interface that allows the surgeons to operate the device. They are actively looking for a commercial partner who will take the new instrument through the FDA approval process including initial clinical trials. “Our best case scenario is that the system could be available to surgeons in four to five years,” Webster said.

Using virtual reality to help teenagers with autism learn how to drive
Using virtual reality to help teenagers with autism learn how to drive. Surveys indicate that about 30 percent of adolescents with ASD either drive or want to drive. That is why Weitlauf, who is an assistant professor of pediatrics at Vanderbilt University Medical Center and part of the Vanderbilt University Kennedy Center, is collaborating with a team of Vanderbilt engineers to develop a special adaptive virtual-reality driving environment for individuals with ASD. Although there is no single accepted treatment for ASD, there is growing agreement that individualized behavioral and educational interventions can have a positive impact on the lives of these individuals and their families, she explained. There are a number of off-the-shelf driving simulators available, but none have the capabilities built into the Vanderbilt VR Adaptive Driving Intervention Architecture (VADIA). Not only is it specifically designed to teach adolescents with ASD the basic rules of the road, but VADIA also gathers information about the unique ways that they react to driving situations. This will allow the system to alter driving scenarios with varying degrees of difficulty to provide users with the training they need while keeping them engaged in the process. Ultimately, it may also help screen individuals whose deficits are too severe to drive safely. The research setup consists of an automotive-style bucket seat, steering wheel, brake and gas pedals in front of a large, flat screen display on a height-adjustable table. The black box sitting directly below the screen is an eye-tracker that keeps track of where the driver is looking. Participants don a headset containing electrodes that read the electrical activity of their brain (EEG) and they are hooked up to an array of physiological sensors that record the electrical activity of the driver’s muscles (EMG), electrical activity of the heart (ECG), galvanic skin response, blood pressure, skin temperature and respiration. The elaborate monitoring allows the researchers to determine if the driver is engaged or bored by the simulation. The simulator portrays a city with four different districts – downtown, residential, industrial and arboreal – that is ringed by a freeway. It is programmed with four basic types of driving scenarios: turning, merging, speed and laws. Speed scenarios involve those that require the driver to change their speed, such as entering or leaving school zones, street maintenance areas and changes in posted speed limit. Laws scenarios involve obeying traffic signs, such as stop and yield. The software includes a number of factors that can be changed to increase or decrease the degree of difficulty involved. It can vary the speed and aggressiveness of the autonomous vehicles the driver encounters. It can vary weather conditions from sunny, overcast and rainy. It can also alter the responsiveness of the brake pedal, gas pedal and steering wheel to mimic the effect of slippery or dry pavement. The system is designed to give drivers immediate feedback when they make mistakes. In its basic, performance mode, the simulator reacts when the driver makes a performance error such as exceeding the speed limit or failing to stop at a red light. The simulation stops and a text message is displayed on the screen and repeated audibly that explains the mistake and corrective steps the driver can take to avoid it. In its second mode, the simulator not only reacts to performance errors, but it also reacts when the driver fails to pay attention to important elements in the scene, such as stop signs, other vehicles and pedestrians. These objects are marked in the computer and if the eye tracker determines that the driver has not looked at such an object for a period the researchers have determined as adequate, the simulation stops and issues an explanatory error message. This would definitely be a good teaching aide for driving, without a doubt,” confirmed 16-year old Brandon Roberson, an adolescent with Asperger syndrome who has been participating in the studies. He has his learner’s permit and would like to drive by himself. “Going out and doing what I want to do is something I have never been able to do because I have not been able to drive.” To learn more about this research, click here: http://news.vanderbilt.edu/2016/07/using-virtual-reality-to-help-teenagers-with-autism-learn-how-to-drive/ Follow Vanderbilt on Twitter: https://twitter.com/vanderbiltu, on Instagram: http://instagram.com/vanderbiltu and on Facebook: https://www.facebook.com/vanderbilt.

The Human Advantage: A New Understanding of How Our Brain Became Remarkable
“People need to drop the idea that the human brain is exceptional,” said Vanderbilt University neuroscientist Suzana Herculano-Houzel. “Our brain is basically a primate brain. Because it is the largest primate brain, it does have one distinctive feature: It has the highest number of cortical neurons of any primate. Humans have 16 billion compared with 9 billion in gorillas and orangutans and six-to-seven billion in chimpanzees. It is remarkable, but it is not exceptional.” In her popular science book The Human Advantage: A New Understanding of How Our Brain Became Remarkable (MIT Press: March 2016), Herculano-Houzel explains how human brains grew so large, even larger than the brains of gorillas and orangutans, whose bodies are larger than ours. Her answer is surprisingly simple. It is the invention of cooking. “Our big brains are very costly. They use 25 percent of all the energy the body needs each day,” Herculano-Houzel said. “Cooking allowed us to overcome an energetic barrier that restricts the size of the brains of other primates.” Take the case of the gorilla. It must spend at least eight hours per day foraging and eating to support its body and brain. The human brain is three times larger than that of the gorilla. If a gorilla had a brain the size of a human, it would have to spend an additional one and a half hours a day finding food. So there simply aren’t enough hours in the day for the gorilla to support a bigger brain. Likewise, if humans ate like any other primate, we would have to spend nine and a half hours per day eating – every single day. That’s where cooking comes in. “By cooking, I mean cutting, dicing, smashing –all types of food preparation,” Herculano-Houzel said. “Take a single carrot. If you eat it raw, it will take 10 to 15 minutes of vigorous chewing and your digestive system will only capture about one third of the calories. But, if you cut the carrot up and cook it for a few minutes, it takes only a few minutes to consume and your body gets 100 percent of the calories.” The origin of cooking, as Herculano-Houzel defines it, dates back about 2.5 million years ago with the development of the first stone tools. Among other things, these stone tools were man’s first food processors, allowing our ancestors to slice and dice and mash their food. Evidence for the controlled use of fire appears about 400,000 years ago. “Those early tool makers had brains about the same size as gorillas. But, beginning about 1.8 million years ago, the brains of our ancestors began growing steadily, tripling in size over the next 1.5 million years,” said Herculano-Houzel. “It’s amazing that something we now take for granted, cooking, was such a transformational technology which gave us the big brains that have made us the only species to study ourselves and to generate knowledge that transcends what was observed firsthand; to tamper with itself, fixing imperfections with the likes of glasses, implants and surgery and thus changing the odds of natural selection; and to modify its environment so extensively (for better and for worse), extending its habitat to improbable locations.” Follow Vanderbilt on Twitter: https://twitter.com/vanderbiltu, on Instagram: http://instagram.com/vanderbiltu and on Facebook: https://www.facebook.com/vanderbilt.

The tale teeth tell about the legendary man-eating lions of Tsavo
An analysis of the microscopic wear on the teeth of the legendary “man-eating lions of Tsavo” reveals that it wasn’t desperation that drove them to terrorize a railroad camp in Kenya more than a century ago. “Our results suggest that preying on people was not the lions’ last resort, rather, it was simply the easiest solution to a problem that they confronted,” said Larisa DeSantis, assistant professor of earth and environmental studies at Vanderbilt University. The study, which she performed with Bruce Patterson, MacArthur Curator of Mammals at The Field Museum of Natural History in Chicago, is described in a paper titled “Dietary behavior of man-eating lions as revealed by dental microwear textures” published online April 19 by the journal Nature: Scientific Reports. “It’s hard to fathom the motivations of animals that lived over a hundred years ago, but scientific specimens allow us to do just that,” said Patterson, who has studied the Tsavo lions extensively. “Since The Field Museum preserves these lions’ remains, we can study them using techniques that would have been unimaginable a hundred years ago.” In order to shed light on the lion’s motivations, DeSantis employed state-of-the-art dental microwear analysis on the teeth of three man-eating lions from the Field Museum’s collection: the two Tsavo lions and a lion from Mfuwe, Zambia that consumed at least six people in 1991. The analysis can provide valuable information about the nature of animal’s diet in the days and weeks before its death. DeSantis and Patterson undertook the study to investigate the theory that prey shortages may have driven the lions to man eating. At the time, the Tsavo region was in the midst of a two-year drought and a rinderpest epidemic that had ravaged the local wildlife. If the lions were desperate for food and scavenging carcasses, the man-eating lions should have dental microwear similar to hyenas, which routinely chew and digest the bones of their prey. “Despite contemporary reports of the sound of the lion’s crunching on the bones of their victims at the edge of the camp, the Tsavo lion’s teeth do not show wear patterns consistent with eating bones,” said DeSantis. “In fact, the wear patterns on their teeth are strikingly similar to those of zoo lions that are typically provisioned with soft foods like beef and horsemen.” The study provides new support for the proposition that dental disease and injury may play a determining role in turning individual lions into habitual man eaters. The Tsavo lion that did the most man eating, as established through chemical analysis of the lions’ bones and fur in a previous study, had severe dental disease. It had a root-tip abscess in one of its canines—a painful infection at the root of the tooth that would have made normal hunting impossible. “Lions normally use their jaws to grab prey like zebras and buffalos and suffocate them,” Patterson explained. “This lion would have been challenged to subdue and kill large struggling prey. Humans are so much easier to catch.” The diseased lion’s partner, on the other hand, had less pronounced injuries to its teeth and jaw—injuries that are fairly common in lions which are not man eaters. According to the same chemical analysis, it consumed a lot more zebras and buffalos, and far fewer people, than its hunting companion. The fact that the Mfuwe lion also had severe structural damage to its jaw provides additional support for the role of dental problems in triggering man-eating behavior, as do a number of reports of man-eating incidents by tigers and leopards in colonial India that cite similar infirmities, the researchers pointed out. “Our data suggests that these man-eating lions didn’t completely consume the carcasses of their human or animal prey,” said DeSantis. “Instead, people appear to have supplemented their already diverse diet. Anthropological evidence suggests that humans have been a regular item on the menu of not only lions, but also leopards and the other great cats. Today, lions seldom hunt people, but as human populations continue to grow and the numbers of prey species decline, man eating may increasingly become a viable option for many lions.” The study was funded by Vanderbilt University, the Brown Fund of the Field Museum of Natural History and National Science Foundation grant EAR1053839.

Amal Clooney calls Vanderbilt grads to “be courageous”
Human rights attorney Amal Clooney gave her first-ever graduation speech to Vanderbilt’s graduating class of 2018. Clooney’s career as an international human rights attorney places her in the same circles as the most successful people in the world, and she’s asked them to share their secrets. It’s not their advanced education – although that helps, she told Vanderbilt University’s 2018 graduates. It’s not their families, age or ambitions. It’s their character, she said, and particularly their courage. In a Senior Day speech Thursday that brought a packed Memorial Gymnasium to its feet, Clooney took the crowd through historic examples of courage, including Vanderbilt Distinguished Alumnus and civil rights era icon Rev. James Lawson. She shared the stories of her own clients today, who include a journalist jailed for reporting corruption by Azerbaijan's president and an advocate for sexual violence survivors who herself was enslaved by the Islamic State. “We need young people with the courage to say, ‘This is our world now, and there are going to be some changes,’” Clooney said. “My generation is counting on you.” Chancellor Nicholas S. Zeppos awarded Clooney the 2018 Nichols-Chancellor’s Award, created and endowed by Vanderbilt Law School graduate Ed Nichols and his wife, Janice, and given those who exemplify the best qualities of the human spirit. “(Clooney) is, by any measure, one of the world’s foremost international human rights lawyers,” Zeppos said. “She’s taken on the most challenging cases, combining her brilliance with painstaking attention to detail and a deep and abiding belief that the law can accomplish good things.” Clooney, who is donating her honorarium to the Clooney Foundation for Justice, continued the feeling of celebration, encouraging graduates to take a moment to enjoy their accomplishments and then demonstrate what they care about through their careers and the choices they make each day. "Be courageous. Challenge orthodoxy. Stand up for what you believe in,” she said. “When you are in your rocking chair talking to your grandchildren many years from now, be sure you have a good story to tell." The Oxford and New York University graduate said she began her working life as a corporate lawyer earning $200,000 a year. Her yearning to make a difference led her to give that up for a $20,000 a year job as a judicial clerk at The Hague, which launched her current career. “My advice isn’t that you have to be Gandhi or Mandela or Martin Luther King or that you should be a human rights activist or get jobs where the salary decreases at every turn,” she said, then quoted poet Robert Frost. “There will be moments in your life where two roads diverge in the wood, and when that happens, be courageous.” Clooney wrapped up with a quip that brought roars of laughter: “When I told people I was coming to Vanderbilt, I kept being told the same thing: ‘You know, it’s the Harvard of the South.’ Having spent time here, I’d say that Harvard is the Vanderbilt of the North.” Follow Vanderbilt on Twitter: https://twitter.com/vanderbiltu, on Instagram: http://instagram.com/vanderbiltu and on Facebook: https://www.facebook.com/vanderbilt.

Vanderbilt Advances "Organ-on-a-Chip" Research
Have you or someone you know had a bad reaction to medicine? Ever wonder if chemicals in your dry cleaning or bathroom sprays are really safe? A team of Vanderbilt researchers is working on a radical new way to test drugs and toxins. It all starts with an organ on a chip! MORE INFORMATION: • http://news.vanderbilt.edu/2012/07/microbrain/ • Big picture look at "human on a chip" research: http://news.vanderbilt.edu/2013/05/john-wikswo-at-tedx/ • http://www.nih.gov/ Vanderbilt researchers make progress in a multi-million dollar research project to develop a "microbrain" on a chip." Take a millionth of a human brain and squeeze it into a special chamber the size of a mustard seed. Link it to a second chamber filled with cerebral spinal fluid and thread both of them with artificial blood vessels in order to create a microenvironment that makes the neurons and other brain cells behave as if they were in a living brain. Then surround the chambers with a battery of sensors that monitor how the cells respond when exposed to minute quantities of dietary toxins, disease organisms or new drugs under development. Creating such a "microbrain bioreactor" is the challenge of a new $2.1 million research grant awarded to an interdisciplinary team of researchers from Vanderbilt University, Vanderbilt University Medical Center, and the Cleveland Clinic. The grant is one of 17 that are being issued by the National Center for Advancing Translational Sciences at the National Institutes of Health as part of a $70 million "Tissue Chip for Drug Testing" program. The five-year program is a cooperative effort on the part of NIH, the Defense Advanced Research Projects Agency and the FDA. The reason for microfabricating organ simulators containing small populations of human cells -- generally known as organ-on-a-chip technology -- is to bridge the formidable gaps that exist between the tools that researchers currently use to develop new drugs -- cell cultures and animal and human testing. These gaps not only add substantially to the difficulty and expense of developing new drugs but also contribute to the large number of experimental drugs that aren't effective or have unacceptable side effects when they are finally tested on people. The brain is a particularly difficult target for drug development because it is surrounded by three barriers that protect it from molecular or cellular intruders. The most formidable of these is the blood-brain barrier (BBB). It surrounds the blood vessels that service the brain and allows the passage of compounds that the brain needs while simultaneously blocking the passage of other types of molecules, both foreign and domestic. The two other barriers protect the neurons from contaminants in the cerebral spinal fluid and protect the cerebral spinal fluid from contaminants in the blood. Not only do these barriers block potentially harmful molecules, neuroscientists have also discovered that they occasionally alter the chemistry of some of the compounds that they let through. "Given the differences in cellular biology in the brains of rodents and humans, development of a brain model that contains neurons and all three barriers between blood, brain and cerebral spinal fluid, using entirely human cells, will represent a fundamental advance in and of itself," said John Wikswo, the Gordon A. Cain University Professor and director of the Vanderbilt Institute for Integrative Biosystems Research and Education (VIIBRE), who is orchestrating the multidisciplinary effort. Wikswo and his collaborators argue that this new type of brain model should provide new insights into how the brain receives, modifies and is affected by drugs and disease agents. By replicating the forms of chemical communication and molecular trafficking that take place in the human brain, the device will allow them to test the effectiveness of various drug and nutritional therapies designed to prevent both acute injuries like strokes and chronic diseases like obesity and epilepsy, as well as uncovering the potential adverse effects of experimental drugs. The basic microbrain bioreactor involves the integration of several technologies that have been developed and tested independently.

Nanotechnology and the Concrete World: Small Science for a Big Future
Dr. Florence Sanchez, Associate Professor in the Department of Civil and Environmental Engineering at Vanderbilt University (www.cee.vanderbilt.edu) specializes in the study of interfacial interactions (chemical and mechanical) and mass transport processes coupled with chemical reactions as applied to advanced, cement-based composites and environmental systems. Professor Sanchez's research interests include multi-scale experimental characterization (mechanical, chemical, and physical across nano to macro length scales) and computational modeling (molecular dynamics modeling and coupled reactive mass transport modeling) of the nano-engineering, performance, and durability of cement-based composites. Dr. Sanchez is the recipient of a National Science Foundation (NSF) CAREER award in 2006. From 2009 to 2010, she served as Chair for the American Ceramic Society's Cements Division. She is currently a member of the Transportation Research Board Task force on Nanotechnology-Based Concrete Materials (AFN15T), the RILEM technical committee on Reinforced Concrete in the Context of Nuclear Waste Management (TC 226-CNM), and the American Concrete Institute's committee on Materials Science of Concrete (ACI 236) and subcommittee on Nanotechnology of Concrete (ACI 236D). Civil engineering infrastructures include concrete structures (e.g., buildings, dams, bridges, waste treatment plants, waste disposal sites, and nuclear power plants) whose long-term performance and function are critical. The deterioration of these structures with time increases maintainance costs and adversely impacts their operating conditions and increases the risk to public safety. Concrete degradation is one of the most important problems faced by civil infrastructure (ASCE, 2009) and is a large burden on the US economy. Conventional cement-based materials suffer from numerous deficiencies such as lack of ductility, low tensile strength, poor impact resistance, low electrical conductivity, and concerns over long-term durability.
