Video Games That Make the World Better

Many new video games are interactive, educational, and enriching. And they might even improve your gas mileage.
Each year, video games offer more challenging and natural experiences, from motion-controlled action to augmented reality. And each year the games are becoming more popular—not only as a form of entertainment but as a medium for education or even as a therapeutic agent for keeping people’s minds sharp. So what lies ahead? In March, DISCOVER and the National Science Foundation gathered a panel of experts at the South by Southwest Interactive Festival in Austin, Texas, to discuss the future of video games. Amos Zeeberg, the managing editor of DISCOVER’s Web site, moderated the wide-ranging conversation.
Tiffany Barnes is a computer scientist at the University of North Carolina at Charlotte who uses video games as a teaching tool in her college classroom. Jim Bower is a computational neuroscientist at the University of Texas Health Science Center at San Antonio; he is also the founder of Numedeon, the company that created Whyville, a popular online virtual world where children can play educational games and engage in social activities. Lucy Bradshaw, general manager of the video game developer Maxis, is the executive producer of Spore and many other titles. Anne McLaughlin is an experimental psychologist at North Carolina State University, in Raleigh, and the director of the Gains Through Gaming Lab, where she is researching ways in which popular video games can be used to improve elder cognition.
Why have video games become such a pervasive form of entertainment as well as such an enticing tool for education? What is it about the medium that makes it so powerful?
Anne McLaughlin: Play is a very natural place to go for learning experiences. In video games there’s a structure of achievement and reward, and that can be felt in a simulation where you’re trying to understand what the underlying system is, figure out how the gears work, so you can control where the simulation is going. You’re starting to see that more and more, in things like the achievement system that exploded on Xbox Live and has now cropped up in Facebook games. That reward structure makes them different from any other type of activity.
Tiffany Barnes: I think the interaction is the most important part of the games. When I do something in a game and see the effect, that’s where I get to make a new concept, learn something or see something new, explore a curiosity. And that’s the important part that enables learning. There’s not only the motivation of a reward structure, but also an ability to see how other people are doing and compete with them—or maybe cooperate. I think Rock Band is a great example of that, where we can gain more points by everybody’s being in the zone and working together: If someone’s not doing so well, I can rescue him by being really awesome myself.
Lucy Bradshaw: The other thing Rock Band offers is the ability for people of different levels to all play together. I personally would love to see that in more games.
McLaughlin: That’s an excellent point. What I find exciting about the new technology is that it’s blurring the lines between real life and game playing. You can play video games with a cell phone, a computer. I think it’s more and more active. And if you can get generations to interact and be active, well, that seems a lot better than sitting in front of the television.
Bradshaw: Picking up on that, there’s been this wave of communities and MMO [massively multiplayer online] games that take on roles and hierarchical structures. There are mentors who teach other players how to make the games. There are creators, there are modders [who modify existing games]. I mean, the landscape of gamers has changed so dramatically in just the last 3, 5, 10 years because games are looking at the latest technology and utilizing it. There are tweets that come from games: from your characters, from the games themselves, and from the development teams as they make them. There’s an entire social network and platform that Facebook has really adapted.
So is there something fundamentally different about video games that makes them unlike other forms of play?
Jim Bower: We look at this thing and we think it’s new. It’s not. This is something we’ve made in our own image. This thing has flexibility, it’s visual, it’s got auditory, its got an Internet that connects humans together. This is just us.
What are other things primates do? They’re hierarchical, right? They’re social. So what we’re seeing in the evolution of the Internet as well as the gaming/video/whatever-it-is industry is that we’re slowly relearning ourselves. And so, in designing games and play, it turns out play is the core part of how primates learn.
What we’re doing here is trying to capture how humans really learn, how humans really interact, and how humans really build their societies. And in fact it’s not new at all. It’s very old. The problem is, for the last 600 years we’ve been doing it wrong. We haven’t had the technology to do it right.
An early criticism of video games was that they were socially isolating and creatively stifling. Is there any validity to that?
Bradshaw: I don’t think so. If you look at games from the past, kids were really controlling this meta-game of a community of players who interacted with one another and created different roles to play in the meta-game. There were games in which the captains knew the subject matter and they taught other players how to make content or modify things. So I think inherent in video games, and something that we have deliberately built into them, is this ability to extend beyond the box.
Barnes: To the comment that games erase individuality: I think that any person who would say that is playing hardly any games at all. Because not only do we have many different types of games, we are also getting more and more games that can actually help ?you achieve your own goals. We’re starting to have games for exercise, games for meeting other people. You can set your own goals with games now, so they’re just a whole different kind of medium. So someone who says you’re going to lose your individuality with games is just not playing games.

Bower: A very clear trend in the gaming world, and something we set out explicitly to do in Whyville 11 years ago, is to actually involve the individual, allowing you to express yourself and brand yourself with learning. So one of the things you’re seeing, I think, is that smart games—games that involve your actually being able to learn something that gives you an advantage in the social structure —are becoming the more interesting and powerful games. The point is, when games are built assuming that humans have a two-minute attention span, players stay there for about two minutes. The games that drive longer involvement, and The Sims is a good example, are ones that—guess what?—involve your actually having to be intelligent and learn something to play them

The Trillions of Microbes That Call Us Home—and Help Keep Us Healthy

The human body is a habitat for a huge range of harmless and beneficial microbes, which may be the key to fighting disease without antibiotics. 

In the intensive care nursery at Duke University Medical Center, doctors and nurses attend to premature infants in rows of incubators surrounded by ventilators and monitors. As new parents holding packages of breast milk watch their tiny babies, neo­natologist Susan LaTuga makes her rounds, checking vital signs and evaluating how the infants tolerate feeding. She consults with nurses, dietitians, and pharmacists about the course of the day’s treatment for the babies, some of whom weigh as little as one pound and were born as much as 17 weeks early.
At the end of her shift, LaTuga stops at a freezer and inspects stool samples from some of the infants that are at the center of a remarkable new study. Across the Duke campus, technicians are waiting to analyze them with a powerful gene sequencer capable of penetrating the hidden world of the billions of microorganisms growing inside each infant.
LaTuga is one of several medical researchers at Duke working with microbial ecologists to study the development of the human microbiome—the enormous population of microbes, including bacteria, fungi, and viruses, that live in the human body, predominantly in the gut. There are 20 times as many of these microbes as there are cells in the body, up to 200 trillion in an adult, and each of us hosts at least 1,000 different species. Seen through the prism of the microbiome, a person is not so much an individual human body as a superorganism made up of diverse ecosystems, each teeming with microscopic creatures that are essential to our well-being. “Our hope is that if we can understand the normal microbial communities of healthy babies, then we can manipulate unhealthy ones,” LaTuga says.
The Duke study is just one of many projects begun in the past five years that use genetic sequencing to explore how the ­diversity of the microbiome impacts our health. Two of the largest efforts are the Human Microbiome Project, funded by the National Institutes of Health, and the European Union’s Metagenomics of the Human Intestinal Tract. Although these groups have only just begun to publish their findings, it is already clear that the micro­biome is much more complex and very likely more critical to human health than anyone suspected. Understanding and controlling the 
diversity of our germs, as opposed to assaulting them with anti­biotics, could be the key to a range of future medical treatments...

20 Things You Didn't Know About... Nanotechnology

How it might kill us, how it might save us, and how it was used in the smallest ever marketing stunt
1  Get small. A nanometer is about the width of a strand of DNA; if you design, build, or use functional systems smaller than 100 of these, you’re a nanotechnologist.
2  By that definition, we have been doing nanotech for centuries. For instance, the colors in medieval stained glass windows result from nanocrystals created in the heating and cooling of the glass.
3   Size matters. At the nano scale, materials take on unusual properties. Their color, transparency, and melting point often differ significantly from those of larger clumps of the same stuff.
4  Nanoscale bits of metal oxide, carbon fiber, or metal blends can detoxify hazardous waste: Their extreme solubility and chemical reactivity help them zero in on the nasty stuff.
5  This approach is already being used at sites in a dozen states, mostly to clean groundwater fouled by solvents, metals, and petroleum.
6  Brighter colors! Richer flavors! Less spoilage! Those are some of the reasons why companies are dumping nanoparticles into hundreds of products, including cosmetics, sunscreens, and food.
7  Analysts say the global market for manufactured goods using nanomaterials could hit $1.6 trillion by 2013.
8  Uh-oh. Studies show that nanoparticles can work their way into the bloodstream, penetrate cells, and get past the blood-brain barrier. Research has linked such particles to lung damage; the brain may be affected too.
9  But if those particles don’t kill us, they just might save us. Scientists at U.C. San Diego have designed a fluorescent nanoparticle that glows inside the body, making it easier to image tumors and organ damage.
10  Yale researchers have created plastic nanospheres that encapsulate proteins called cytokines, which stimulate the immune system’s killer T-cells. An injection of those spheres could help fight disease and infection.
11  And in a University of Southern California lab, nanotubes have been used to create synthetic neurons (pdf).
12  The USC team is trying to assemble these neurons into functional networks, which would bring us closer to assistive brain implants.
13  In 1989, using an atomic force microscope, IBM engineer Don Eigler became the first person to move and control a single atom.
14  Eigler and his team later used 35 xenon atoms to spell out “IBM,” thus performing the world’s smallest PR stunt.
15  Atoms? Big whoop. Researchers at Princeton and U.C. Santa Barbara can control the spin of a single electron, trapping it in a “corral” created by applying voltage to minuscule electrodes.
16  But they’re not playing cowboy. The breakthrough could lead to powerful quantum computers that store and manipulate data in the spin of individual electrons.
17  Not to be outdone, Stan­ford scientists used scanning tunneling microscopy and holograms to write information within the interference patterns formed by electron waves on a copper sheet. The letters are less than a third the size of Eigler’s “IBM.”
18  Government researchers have created arrays of chromium nanodots that can store magnetic data with unprecedented uniformity. One goal: drawing more complex integrated circuits on silicon chips.
19  For the rodent who has everything. Georgia Tech scientists made piezoelectric generators out of nanowires and attached them to tiny hamster jackets. When the critters ran, the generators created electricity.
20  Zhong Lin Wang, co-inventor of the jacket, envisions a shirt that charges your cell phone as you stroll, or an implanted device for measuring blood pressure that’s powered by your own heartbeat.
