ScienceDaily (Feb. 16, 2012) —
Anqi Zou never thought she would thank video gamers for showing her the way to exciting discoveries in molecular biology. But here she is, acknowledging that the technology she uses to show the inner workings of cells was originally perfected to create realistic images on gaming screens worldwide. No matter. Sam Cho and his students are using graphics processing units -- also called GPUs or graphics cards -- to explore the biomolecular processes in the cell and take on challenges, including a cure for cancer.
"We have hijacked the same technology that creates the detailed gaming scenes on your computer screen to perform molecular-dynamic simulations," Cho said.
Zou is helping Cho push the limits of GPU-optimized cell simulations. This Mathematical Business and Computational Science major is comparing the data provided by GPU and non-GPU simulations.
"Because of the powerful computational ability of these GPU devices that are usually used for gaming, I couldn't help registering for Dr. Cho's GPU programming course," she said. "Halfway through the semester, I was much impressed by the computational performance of the GPUs, and I approached Dr. Cho about working on a research project related to GPU programming."
For his most recent published study, Cho, an assistant professor of physics and computer science, simulated the folding and unfolding of a critical RNA molecule component of the human telomerase enzyme. This enzyme lengthens DNA strands during cell division. It's what makes tumors continue to grow.
Knowing how human telomerase works could lead to cancer therapies that essentially obliterate tumors, Cho said.
His research findings appear in the Journal of the American Chemical Society.
Now, Cho and his research assistants are looking at a much larger cell system -- the bacterial ribosome -- to see what they can uncover through GPU-optimized molecular dynamic simulations. The graphics cards were donated by Nvidia, the company that invented the GPU; Cho developed a new GPU programming course so he could teach Wake students how to use the cards.
The benefit of the GPU-optimized simulations is that they are much quicker to perform. The ribosome simulation, for example, would take more than 40 years on a standard computer. Using GPUs, Cho and his students will see results in a few months.
The end goal is to map the ribosome's functions so researchers can develop antibiotics to specifically kill bacteria.
And that would be an amazing accomplishment, thanks in large part to videogamers, Cho said.
"If it wasn't for gamers who kept buying these GPUs, the prices wouldn't have dropped, and we couldn't have used them for science," he said.
Translation - Portuguese Videogames levam a novos caminhos para tratamento de câncer e outras doenças (13/02/2012)
Anqi Zou nunca pensou que iria agradecer à jogadores de videogames por lhe mostrarem o caminho rumo à incríveis descobertas na biologia molecular. Mas aqui ela está, reconhecendo que a tecnologia que usa para mostrar o funcionamento interno das células foi originalmente aperfeiçoado para criar images reais que aparecem nas telas de jogos no mundo inteiro. Não importa. Sam Cho e seus estudantes estão usando unidades de processamento gráfico -- também chamadas de GPUs ou placas de vídeo -- para explorar os processos biomoleculares nas células e buscam também desafios, incluindo a cura para o câncer.
"Nós reutilizamos a mesma tecnologia que cria as complexas cenas de jogos na tela do seu computador para realizar simulações dinâmicas moleculares", diz Cho.
Zou está ajudando Cho a ir até os limites da simulação de célula otimizada por GPUs. Este Centro Matemático e Computacional importante está comparando os dados provenientes das simulações, tanto as que vem das GPUs quanto as que não vem.
"Por causa da poderosa capacidade computacional dessas GPUs que são geralmente usadas em jogos, eu não pude resistir e me registrei no curso de programação em GPU do Dr. Cho", ela disse. "Durante o semestre, eu fiquei muito impressionada com a performance das GPUs, e então conversei com o Dr. Cho a respeito de trabalhar num projeto de pesquisa relacionado à programação delas."
No seu estudo mais recente, Cho, um professor assistente de física e ciência da computação, simulou o dobrar e o desdobrar de uma importante molécula RNA que compõe a enzima telomerase, presente no corpo humano. Essa enzima alonga as fitas de DNA durante a divisão das células. É isso que faz os tumores continuarem a crescer.
Conhecer o funcionamento da enzima telomerase pode levar à terapias de câncer que podem eliminar os tumores, disse Cho. Suas descobertas aparecem no jornal da American Chemical Society.
Agora Cho e seus assistentes estão observando um sistema de célula bem maior -- o ribossomo bacteriano -- para ver o que podem descobrir atráves de simulações moleculares utilizando GPUs. As GPUs foram doadas pela NVidia, empresa que inventou a placa de vídeo. Cho desenvolveu um novo curso de programação em GPU então ele pôde ensinar aos alunos da universidade de Wake Forest como utilizar as placas.
A vantagem de usar simulações com GPUs é que elas são muito mais rápidas. A simulação do ribossomo, por exemplo, demoraria mais de 40 anos num computador comum. Usando GPUs, Cho e seus alunos verão resultados em poucos meses. O objetivo final é mapear as funções do ribossomo para que então os pesquisadores possam desenvolver antibióticos para eliminar bactérias específicas. E isso seria um feito fantástico, graças (em grande parte) aos jogadores de videogames, Cho disse.
"Se não fosse o fato deles terem continuado a comprar essas GPUs, os preços não teriam abaixado tanto, e nós não poderíamos tê-las usado para a ciência", disse ele.

Bio
I'm starting my career as a freelancer translator, as I studied English for many years here. I've studied for about 3 years, and finished an advanced english course at CENEX - UFMG, Brazil.
Looking forward to work with translations, especially IT and computers. I have also degree in Computer Networks at Centro Universitario UNA.
