CRIME

Police charge student for art vandalism Julie Heffler

THE DAILY COUGAR Shocking the Houston Police Department and art critics alike, UH student Uriel Landeros has been charged with two thirddegree felonies, criminal mischief and felony graffiti, after allegedly defacing Picasso piece “Woman in a Red Armchair” at the Menil Collection on Friday. A video posted on YouTube last week shows Landeros walking up to the painting, spraying on an image and walking away. According to the man who shot the video, an anonymous source, Landeros claimed to be honoring Picasso’s work by spraying “conquista,” Spanish for “conquest,” and a picture of a bull onto the painting. Crime Stoppers, the organization that identified Landeros, is calling upon Houston residents for their help in capturing the University student.

“Landeros is described as a white male, standing 5’8”, weighing 180 lbs. Anyone with information about the location of Uriel Landeros is asked to call Crime Stoppers,” Crime Stoppers wrote in an email. Vance Muse, the communications director at the Menil Collection, recounts the steps taken by the museum once the crime was discovered. “(The graffiti) was spotted instantly. Luckily, we have a conservation lab, a world-renowned lab, right down the hall. The painting was removed and rushed down there where it now undergoing study, treatment and repair,” Muse said. “Our Chief Conservator, Brad Epley, has (not been) talking to the press because he has been so intent on restoring this piece.” Muse said he is thankful that despite the incident, “Woman in a PICASSO continues on page 3

Remotes rife with disease Research team surveys hotels, find the dirtiest items Channler Hill

THE DAILY COUGAR Recent Conrad N. Hilton College of Hotel and Restaurant Management graduate, Katie Kirsch, a recipient of the Summer Undergraduate Research Fellowship program for summer 2011, took her opportunity head on. Sparking a collaborative effort between two additional schools, Purdue University and the University of South Carolina, Kirsch and a

researcher from each school sampled swabs from various surfaces in hotel rooms in South Carolina, Indiana and Texas. According to the study, one hotel was sampled from each state, while three hotel rooms were sampled from within the particular hotel, ending with a sample size of nine. The hotel rooms were all average-sized, containing two queen beds, and in each hotel room, samples were taken from 19 areas. GERMS continues on page 2

RESEARCH

Disabled use mind control Professor creates movement device that can be operated through thoughts Alexandra Doyle

THE DAILY COUGAR Jose Contreras-Vidal, a professor of electrical and computer engineering at UH, is working on a revolution in the realm of bionic robotics. He is working to give the disabled the gift of mobility, not through wheelchairs or joystick controlled apparatus, but through a set of robotic legs modified to function under the direction of the brain itself. The Rex Bionics Robotic Exoskeleton is a contraption that fits around each leg and the torso, along with two armrest extensions and a joystick. The user is strapped and braced into the device, which is capable of walking up stairs and is stable enough that it cannot be unintentionally knocked over with a person inside of it. Contreras-Vidal has been working to harness the electrical impulses of the brain and translate them into commands for the REX machine. “Think about a symphony; it’s a collection of instruments and players that synergistically work to produce a musical piece,” Contreras-Vidal said. “The brain consists of multiple areas, all somewhat specialized — just as the musical instruments

— and the concerted actions of the ensemble results in in a neural symphony leading to cognitivemotor actions and movements.” According to Contreras-Vidal, the major way in which his work differs from other research is that it focuses on the lowest frequencies of the neural impulses of the brain to decipher those associated with motion. Another major difference is the use of electroencephalography instead of intracranial electrodes or receivers that must be implanted surgically into the brain. Contreras-Vidal said this was an unconventional approach. “It was thought to be very hard, if not impossible, to ‘read the brain’ using EEG with enough accuracy to develop neural interfaces. Our work has not been simple,” Contreras-Vidal said. Contreras-Vidal’s accomplishments with REX come on the heels of his research on developing a brain-to-computer interface at the University of Maryland. He was awarded a Research and Development Award for the School of Public Health. This award-winning research included moving a cursor on a screen when subjects thought about moving it, giving great implications not only for the realm of medicine but also for that

of video games and virtual gaming communities. Contreras-Vidal decided against trying to wrestle with intracranial electrodes because of the issues associated with the technology. “There are still many unknown and known problems with invasive methods based on intracranial electrodes. Some of these problems are associated with the surgical risk, motion of the electrodes, biocompatibility, degradation of signal integrity,” Contreras-Vidal said. “There is much interest and federal funding in understanding why intracranial electrodes fail, because this represents a road barrier for clinical use.” According to Contreras-Vidal, his “NeuroRex” carries none of the risks associated with intracranial electrodes and still responds to thought. On June 13, the Massachusetts Institute of Technology Enterprise Forum of Texas hosted a series of lectures on “New Innovations in Medical Robotics” at the Methodist Hospital Research Auditorium where Contreras-Vidal unveiled his work with Eugene Alford. Alford is a patient who is paralyzed from the waist down. He REX continues on page 3
