Gamers beat algorithms at finding protein structures Today's issue of Nature contains a paper with a rather unusual author list. Read past the standard collection of academics, and the final author credited is... an online gaming community. Scientists have turned to games for a variety of reasons, having studied virtual epidemics and tracked online communities and behavior, or simply used games to drum up excitement for the science. But this may be the first time that the gamers played an active role in producing the results, having solved problems in protein structure through the Foldit game. According to a news feature on Foldit, the project arose from an earlier distributed computing effort called Rosetta@home. That project used what has become the standard approach for home-based scientific work: a screensaver that provided a graphical frontend to a program that uses spare processor time to solve weighty scientific problems. This is typically an energy minimization problem. Starting with algorithms, ending with brains

Five fingers of evolution - Paul Andersen In his talk, Paul Andersen explains the five causes of microevolution. Research one example for each cause in the human population. Use the following population simulator to simulate microevolution: Run the simulation using the default settings.

In at least one case, scientists turned a prickly biochemical problem into a game and found that the gamers could typically beat the best computer algorithms out there. But all that work was done on cases where we already knew the answers, which was how we were able to measure the gamers' success. Now some researchers have taken this approach one step further and created a hybrid project that mixes volunteers with lab-coated workers. 37,000 enthusiasts were given the chance to take on algorithms in designing new RNA molecules. And once the gamers had a chance to vote on the best designs, the winning designs were sent to a lab, synthesized, and tested. A consortium of researchers at Carnegie Mellon, Stanford, and Seoul National University put together what they called a Massive Open Laboratory. At least, energetically stable based on calculations.

Diseases - Manual - Activity 3, page 1 At a Glance Focus: Students investigate the growth of bacteria in the presence of antibiotics and use the results to explain a case of antibiotic-resistant tuberculosis, presented in an Internet-based interview. Major Concepts: The re-emergence of some diseases can be explained by evolution of the infectious agent (for example, mutations in bacterial genes that confer resistance to antibiotics used to treat the diseases). Objectives: After completing this activity, students will be able to explain how antibiotic treatment results in populations of bacteria that are largely resistant to the antibiotic and describe inappropriate and/or questionable uses of antibiotics. Prerequisite Knowledge: Students should be familiar with bacterial growth and with evolution by natural selection. Introduction In 1943, penicillin was introduced as the "magic bullet" for curing many infectious diseases. The primary reason for the increase in antibiotic resistance is evolution. Materials and Preparation 1.

Believe in Ohio STEM videos The Believe in Ohio program invites high school and college students, their instructors and the community to take a virtual field trip into the innovation economy of the future that is being built in Ohio through a series of six, free, regionalized, online courses. What this course is about and why is it important? Our nation is being challenged on an unprecedented level to maintain its historic prosperity. In the face of this challenge, over the last decade, the State of Ohio and its regions have been building Ohio’s innovation economy of the future. Today, the State of Ohio offers great promise for students who want to build a prosperous future for themselves by developing an entrepreneurial mindset, working hard, and applying what they are learning to develop the new products and services and jobs of the future.

Making Makers | Learning Labs Together, Kids Learning Code, Maker Kids, TIFF and Toronto Public Library, have developed comprehensive, maker curriculum for educators who work in formal and informal learning environments with the objective of increasing Toronto youth access and engagement with advanced technology and digital tools! Our workshops and activities allow youth to create something with purpose, driven by their own vision and also empower teachers to be makers. We are hosting Train the Trainer Symposiums wherein the educators can learn how to run and modify activities by doing them.
